General Noob Root and ROM update Questions - Nexus 7 Q&A, Help & Troubleshooting

So I am new to the whole Root and ROM Android arena. And I came up with a few questions that hopefully you guys can help me with.
1. I read people saying they lost their ROOT after an update from 4.1 to 4.2 or 4.2.1 to 4.2.2? How did this happen for them?
Do you have to Un-root and flash to stock before updating to a different build (Such as 4.1 to 4.2 or 4.2.1 to 4.2.2)?
2. Right now I am using a custom ROM on Android Version 4.2.2.... if a new Custom ROM with a new android version released (Let's say 4.2.3) can I flash from one Rom to the other with just wiping Cache/Factory wipe and Dalvik Cahce or is there something else I would need to do because of the Android version update?
Sorry those two questions above are very similar but I wanted to ask them both ways.
3. If I were to get bored of the Custom ROM I am currently on. Are there any Best Practices "rules" I should know about when switching from one custom ROM to another?
4. Last if I am on a custom ROM with a nightly build..... is it more common to update to every nightly build that releases? Or is it more common people to only pick and choose choice nightly build versions. And if people do update to every new Nightly build.... can you update too much and destroy your device?
Sorry guys I know these seem like very basic questions..... and Yes I did search the forums. However while I found some very basic answers nothing went into great depth in explanation. All the answers seemed to be very vague.

does anyone have some suggestions on where to find these answers?

1. If you are on stock, rooted, and you update versions of the OS, you are essentially UPDATING the /system partition. That is how you lose 'root' when upgrading. If you modify any system files while rooted, you have to either revert to stock or change those modified files back to the original before running the update.
2. Just run FACTORY RESET in your custom recovery and flash the new custom rom. No need to wipe any caches (/cache is wiped during a factory reset anyway). It doesnt matter what version to what version. Sometimes new versions might require new bootloaders, but you will be bombarded with that information here if that becomes the case.
3. See number 2. Its the same thing. backup your apps with Titanium Backup, do a Factory Reset in custom recovery and flash new rom....done.
4. doesnt matter. you can update as much or as little as you like. some people prefer stability over new shiny, but then others are just crack-flashers....and will literally flash ANYTHING posted to see what happens

Thanks I really appreciate the response. :good: You'd be surprised how many "Tiny Parts" of answers you get from searching. Very rarely the whole answer you need.
I am glade to hear that Question 2 only requires you to just factory rest. From the misinformation gathered on other forums... I was starting to think you had to flash back to stock before updating to another Custom ROM Build.

@20mmrain
You've probably looked at a number of posts by confused newbs. For better or worse, this site is nothing like a moderated wiki, so you find treasure mixed in with trash.
Rooters fall into four broad classes:
(a) Those that "root & modify" stock ROMs
(b) Those that abandon stock and use custom ROMs and kernels
For each of the above cases, there are diligent and careful users who make full (nandroid) backups... and lazy idiots who do not. It is almost always the lazy idiots you observe coming in here in a panic, independent of whether they are in class (a) or (b).
Beyond that, newbs taking approach (a) seem to perpetually labor under the false impression that their modified versions of a stock ROM should be able to be upgraded by the OTA process - when in fact that there is absolutely no reason to believe that. The OTAs carefully check hundreds of different files before they perform any changes; if even a single one of them has been altered, the OTA aborts without making any changes.
It is *possible* that if none of those hundreds of files are changed that an OTA will succeed on a "nearly stock" ROM. When this happens though, it is quite typical that:
- the "su" binary (part of a root kit) in either /system/bin or /system/xbin gets its' setuid permissions reset by a recursive permission-setting command in the OTA
- the custom recovery can possibly be overwritten by the new stock recovery.
Folks tend to refer to either of the above as "losing root". True in principle, but they are trivially fixed up - if the user actually understands how Android rooting works. (With fastboot, you simply reflash the custom recovery, boot into that and reflash the same root kit originally used).
It's too bad that folks who put together rooting guides seem to neglect putting an emphasis on making backups. They give you both security and freedom.
Bottom line: whatever you choose to do, make nandroid backups. You don't need to keep them all on the tablet - but for convenience reasons, you should have at least one known good ROM as a backup available to be restored.
good luck

Wow that is a really in-depth explanation and that is exactly what was looking for! Since I have been working in the IT world for years I will say with pride that I am an individual who believes in safety first and always back up any important project I am working on! So I am happy to hear I made the right decision there.
I guess a great deal of my questions also stem from working in a windows based world for so long ....that I am still learning Linux/android.
Right now I do keep a nandroid backup on my nexus 7 but only one. How backups do you have? And do you just keep the rest on a thumb drive?

At the moment I have 6 on the tablet - all generated in the last 60 days. Two in the last two days (one a rooted stock/jdq39, another a cm10.1 nightly). Plus recent TiBu market app & data backups. 32 GB model, so I have plenty of room.
That doesn't reflect any particular strategy or goal. I hook it up to a PC every once in a while and at that time either copy off any backups worth saving or delete them. Most of the those I have on the PC will eventually be deleted as well without ever being used. You could use a USB key if you want to. Really you only need to keep one on the tablet - mostly as a convenience in case you wedge your daily driver ROM with some random mod: you can restore a working ROM right from your tablet rather than having to find a USB key or return to your PC to get the tablet booting again.
There is one type of ROM backup that I think is very useful to keep a permanent copy of - a pure stock ROM. The reason for that is that any radio images (tilapia) or bootloader upgrades that are *sometimes* delivered by OTA can be trivially installed by:
- make a backup of the current ROM
- restore a pure stock ROM backup (including the stock recovery! ***)
- take the OTA
- ***soft-boot a custom recovery and make a backup of the NEW stock ROM (including its' recovery!)
- hard-flash the custom recovery to the tablet
- restore the backup from the first step above.
Doing things this way is the safest possible way to install either a bootloader or a radio image. Not only that, but for folks that prefer to mod stock ROMs, it gives them a backup archive of /system to recover arbitrary (stock) files from.
*** soft-booting a recovery is the most convenient way to capture a stock recovery as part of a nandroid backup. I.E.
Code:
fastboot boot recoveryimagefile.img
If you hard-flash a custom recovery before you make a nandroid backup of a stock ROM, you lose the opportunity to get a copy of the stock recovery along with the rest of the stock ROM.
good luck

Asus Transformer EPIC NOOB GUIDE.

In the process of updating information for ICS update and custom ROMs, please hold tight!
A lot of folks have been coming in with newly purchased TF101's lately, which is AWESOME, it means the community will go on longer than the expected life of the device probably, since the TF201 and TF700 have come out and are seeking to replace our beloved TF, this is good news that people still buy the OG Transformer.
That said, there have been the same problems posted by new users, over and over, and sure there are guides for just about everything. But why not one on..just...EVERYTHING?
Here we go, troubleshoot problems and learn your device, the noob way! The EPIC TF101 THREAD BEGINS!
All the typical disclaimers apply, if you mess your stuff up, it is your fault not mine. I did not discover any of these methods, develop any of these tools, or do anything else but compile it all in one epic post. This should be everything you need to know as a noob, I do not take credit for anything, except for making it all easily accessible to those who are unwilling/unable to spend the hours searching that I did. In other words, I did a lot of work for you, but others had done the work for me first. Full credit to them.
What is ROOTING? And why do it?
So you bought a new TF, and you want to root it? Or you want to know what rooting is, for that matter? Rooting is a method of obtaining what is called 'Root Access' to your device, giving you control of it. The 'Root' is the parent directory of your device's internal memory, where the system files are stored. Generally this is kept from your access, you will need to get your device 'rooted' in order to change the system. Once rooted, you will have an app installed called 'Superuser' which will selectively grant applications permission to alter or access your root directory. This method differs on every device, but don't worry- we have a very easy device to root.
VERY IMPORTANT! Do NOT use any of the tools here WHILE YOUR DOCK IS PLUGGED IN!! All these are for use with the TF101 unit BY ITSELF! Please don't brick your device or mess something up by trying it with the dock plugged in!
There have traditionally been several ways to accomplish this for our device, as new applications and tools are developed to make it easier it has gotten to be a very simple process. Which method you use will depend on what SBK version (Secure Boot Key) Transformer you have, and also that model's firmware version. Your firmware version can be located by going to Settings>About Tablet. Current version is 8.6.5.21 (TF101) or 8.6.6.23 (TF101G). When either firmware version (also referred to as the 'stock ROM' sometimes) can be used, it will be listed similar to '8.6.x.19', where x can be 5 or 6 for TF101 or TF101G, respectively.
KNOW YOUR SBK VERSION
As a TF owner looking to mod your device, you need to know that there are multiple SBK versions, primarily SBK1 and SBK2. There may possibly be other versions to come even. All you need to know is, that as of right now, SBK1 is the only model that can utilize a tool called NVFlash to UNBRICK your device if you mess it up too badly, and it is difficult to tell which SBK version you have. In order to find out, there are a few tools out there- one of them is for mac only, called SBKDetect found here
http://forum.xda-developers.com/showthread.php?t=1232612
Another is primarily for Linux, but saavy Windows users can always boot from a Linux live CD on their machines to use it, called SBKDetect v2, here;
http://forum.xda-developers.com/showthread.php?t=1290503
The other way, if you are like me, and don't have Linux-abilities at the time of this writing (I'm working on that), you can always just GO FOR IT and try to flash a modded ROM via NVFlash. If you are SBK1 it will succeed. If not, it will fail. No harm done. Of course that means skipping ahead of a lot of learning first, so it is not advised IMO. It also means that if you DO have an SBK1 tablet, you just wiped all your data. It is not absolutely necessary to determine which SBK you have in order to root and mod your device.
A hit-or-miss way of detecting your SBK version is by looking at your device's serial number, located on the bottom of the device on a sticker. It will take the form of:
B70KAS638075
The ONLY digits you need to know are the FIRST THREE. Older models are SBK1. Manufacturing started at Bxx, and has gone to Cxx this year. All Cxx serial numbers will be SBK2. In fact it was in the middle of the B70 manufacturing that they changed the SBK version, so if you are B60, B50, B40 etc..you are sure to be SBK1. If you are B80, B90, C10, etc, you are sure to be SBK2. B70 owners, it's a coin toss. You must use one of the other methods to determine it.
The only thing that differs between SBK1 tablets and SBK2 tablets is the use of NVFlash. SBK2 cannot use NVFlash, so if you end up botching both your recovery and your ROM, and cannot boot into either, then you are SCREWED, so I would suggest reading everything before attempting to mod your device if you are an SBK2 owner.
NVFlash and APX mode
This was an early method used to root and flash recovery/roms, and is still a very useful application to have saved on a disk somewhere in the event that you own an SBK1, as it renders your tablet practically unbrickable. It can be found here;
http://forum.xda-developers.com/showthread.php?t=1123429
To use it you must enter APX mode on your TF101. This is tricky and confuses many users. The procedure is;
1. Press and hold volume UP and POWER buttons at the same time (it doesn't matter if the TF101 is on or off, if it is on, simply wait until it shuts off before proceding).
2. HOLD these buttons for approximately SIX SECONDS.
3. Plug TF101 into PC and listen for it to chime that it has detected it, it should load drivers and device will be listed in Right Cick>Computer/Properties/Device Manager/USB Universal Serial Bus Controller (or similar) as NVIDIA, not as ASUS.
4. If it does not, power on the TF and try again until it does.
NOTE: This is the only way to know if it is in APX mode as the screen remains powered off completely.
Once in APX mode now you can use NVFlash tool, place the system, boot, and recovery .img files into the root of the folder you extract NVFlash into and execute the download.bat file. If at any point the flash fails, this likely means you are SBK2.
ADB Mode
This stands for Android Debugging Bridge. This is not to be confused with APX mode, which is a separate thing entirely. To learn more about your device's ADB mode, see this excellent thread here;
http://forum.xda-developers.com/showthread.php?t=1071584
Another quick guide for ADB can be found here:
http://www.droidforums.net/forum/droid-hacks/6865-how-use-adb-all-commands-options.html
(sorry for the off-site link, trying to keep it as xda pure as possible!)
Razorclaw Root Tool
Razorclaw is by far my favorite method of rooting for the TF, it can be found here;
http://androidroot.mobi/2011/11/14/introducing-razorclaw-v1/
It does not matter what SBK version you have to use Razorclaw, that is why I prefer this method of rooting.. HOWEVER, it does require you to be using an older firmware version though. If you are on version 8.6.x.21 or above, you cannot use razorclaw. It works best on firmware 8.6.x.19. You simply install the app and follow the instructions (Root me nao!). It is a one click, native rooting tool.
If you are not on this firmware version and razorclaw will not work, there are options. You can either roll back your firmware version, the method is located here;
http://forum.xda-developers.com/showthread.php?t=1417006
If you are unsuccessful or want to try another way, you can use Nachoroot or ViperMOD.
Nachoroot Root Tool
This is one of the newer root tools, it is for all firmwares and all SBK versions, and can be found here;
http://forum.xda-developers.com/showthread.php?t=1427838
Nachoroot uses the ADB (Android Debugging Bridge) via a command prompt or terminal, all necessary drivers must be installed.
I cannot personally get this method to work because my PC will not install the drivers properly, and since I don't need the tool any longer, I must admit I've never used it, thus my bias towards Razorclaw. So, if you are having similar driver issues, rolling back firmware and using RC might be quicker and more painless.
ViperMOD Root Tool
ViperMOD is another method, similar to and related to Nachoroot, in that it uses the PC to root your TF101 and will need the appropriate drivers installed. The main difference being that this method will install Superuser as well. The other major difference is that while Nachoroot is done with a command dialogue, ViperMOD is done with a much simpler command interface (choose a number from a list of options rather than typing out commands). Interestingly enough, both of these methods work on both the TF101 and the TF201, and both methods appeared about the same time (posted on January 4th 2012). ViperMOD and Nachoroot represent the most recent methods for gaining root on the TF101. ViperMOD is unique that it has a feature to unroot your device as well, though you will need to have the stock ROM and recovery files available to completely return to stock. Find out more about ViperMOD here;
http://forum.xda-developers.com/showthread.php?t=1427125
I also cannot attest to the use of ViperMOD personally, I have used other methods, but many users have reported it quite simple to root with.
A quick breakdown;
Razorclaw, Nachoroot and ViperMOD will ONLY ROOT your device. No data will be wiped and you will have to install recovery later. In the case of Nachoroot, you will have to download superuser from the market, Razorclaw and ViperMOD installs it for you.
NVFlash WILL WIPE EVERYTHING! So understand that it will rewrite your TF101 internal memory competely and install a rooted ROM (or whatever you tell it to) on your device, as well as a boot and recovery image.
REGARDLESS OF THE ROOTING METHOD YOU CHOOSE, PLEASE READ THAT METHOD'S INSTRUCTIONS VERY CAREFULLY!!!
[Q]How do I know if I am rooted?
[A] Simply check within your app drawer for the superuser application (or download it from the market if using Nachoroot), to verify it works, download titanium backup and begin a batch backup and see if it asks permission, and if the batch completes. If you are not rooted, either try your first method again or try an alternate method.
Tip: Immediately after rooting you should back up your system with Titanium Backup, skip ahead to that section to learn how before moving on.
Recovery Mode
The stock recovery mode on the TF101 shows one of two screens; a green android in the middle of the screen with gears turning inside it, or the same android with a yellow triangle with an (!) inside it instead. The gears obviously mean it is working (flashing firmware), the (!) means something has gone wrong (no file found, flash failed). To enter recovery mode, you need to press and HOLD Volume DOWN and POWER when the device is powered OFF. As soon as the screen comes on, RELEASE THE POWER BUT HOLD THE VOLUME STILL. You will see white letters appear in the upper left corner of the screen, it is now okay to release the Volume DOWN button and quickly (within 5 seconds) press the Volume UP button to enter recovery mode. There are also applications, such as Reboot to Recovery, available on the market, that will allow you to reboot your device with one click into recovery mode without having to toggle your power/volume buttons.
About Stock Recovery Mode
The stock recovery mode is absolutely required to install official Asus OTA (Over The Air) updates. Unless your device is unrooted with a stock recovery mode, you will not be able to install any OTA updates, this includes ICS!! It can also be used to install (or RE-install if it were) your STOCK ROM (only official, digitally signed files will be accepted by the stock recovery to flash over the firmware, no modded roms will work). The method for doing this is outlined in the link for rolling back your firmware version above but I will summarize;
Recovery mode searches your external SD card ROOT DIRECTORY(and the internal memory's cache directory, but this is not useful for any practical reason for you) for these Asus files. The files must be named either;
EP101_SDUPDATE.zip
or
XX_user-epad-Z.Z.Z.ZZ.zip (X = firmware region stamp, WW, US, DE, etc, and Z - firmware version, 8.6.5.19, 8.6.6.21 etc)
I personally find the second configuration to work best. If stock recovery finds a file named appropriately and signed with the proper digital signature it will install it, and you will see gears turning. Otherwise; (!). Remember, it has to be on the SD card in the ROOT, not in a folder or it won't find it.
CWM Recovery Mode
ClockWorkMod Recovery mode replaces your stock android recovery mode, and gives you control of;
Flashing (installing) ROMs, recovery, themes and app packs, patches, kernels and more
Wiping cache, dalvik cache, system, data, etc
Backup and Restore features
Advanced features you probably won't need like fixing permissions and mounting partitions etc.
The important thing to know is if you want to be able to change ROMs right from your device, you need this. In order to install it on the TF, you can use an app called RecoveryInstaller, located here;
http://forum.xda-developers.com/showthread.php?t=1346180
It is a one-click app just like Razorclaw, download and a single click will install CWM for you, though it may be an older version it will work fine to install the most recent version, directly from CWM once you enter it the first time. You will need to give it superuser permission as well. The newest CWM for the TF101 is called ROGUE XM and it is available here;
http://forum.xda-developers.com/showthread.php?t=1446019
Simply place the newest version on your SD card where you can find it, and use the 'install from SD card' option to navigate to the new version file and select it, which will flash the recovery..then you will need to reboot.
CWM Recovery can also be installed when flashing your device from NVFlash, and the NVFlash versions of ROMs almost always contain the most recent versions of the CWM recovery as well, thus making an NVFlash a one-step procedure (flashes both ROM and recovery at same time). The risk of the one-step procedure is if you are using corrupted images or something unexpected occurs you may end up BOTCHING both recovery and ROM at the same time..of course- if you are SBK1 anyways, just reflash it with a different ROM and it will be fixed.
Once you have installed the latest CWM recovery now you will want to start flashing ROMs and Kernels. I will not be posting links to the custom ROMs and Kernels because there are too many of them, that will be your homework.
Custom ROMs
We are blessed to have some great devs working on our humble TF101. That said, the procedure to flash a ROM through CWM is simple;
1: Download desired ROM and place into your external SD card somewhere you will be able to find it, it doesn't matter.
2: Boot into recovery and go to Backup and Restore and make a backup file. This is commonly referred to as a 'Nandroid' backup, and will backup everything from your ROM to your Kernel to user files.
3: Once backed up, proceed to factory reset and wipe cache partition and dalvik cache, located in the 'advanced' menu.
4: Install from SD card, navigate to your directory and find your ROM (ONLY FLASH THINGS THAT ARE MADE SPECIFICALLY FOR THE TF101! Be sure it is compatible with your device!) and select it, scroll to yes...read and follow instructions. Tapdance and sing ABC's while making some breakfast- and you are done!
5: Reboot device
Please be sure to flash only files that are meant to be flashed via CWM, as some ROMs will also have an NVFlash version, which will not work in CWM.
The Stock ROM currently provided with the TF101 is Android 3.2.1, which is called Honeycomb (HC) which is exclusively for tablets, we are all awaiting the release of Android 4.0 commonly known as Ice Cream Sandwich (ICS) which will merge the operating systems used on phones and tablets. Asus has said it will be out soon, so don't ask when it is coming! To learn more about the different Android versions, read this;
http://en.wikipedia.org/wiki/Android_version_history
I would suggest also to anyone wanting to modify their Android device to understand the history of Android itself and what it is, here;
http://en.wikipedia.org/wiki/Android_(operating_system)
Kernels
The kernel is the underbelly, the brain of the ROM. The kernel is what tells the hardware what to do when you interact with the software of the ROM. Most ROMs, I dare say almost every ROM unless specifically noted, does NOT come with it's own kernel but uses the kernel you have installed now on the device, unless it is a stock ROM, in which case most of them DO have kernels included. You want to be sure if what you are flashing has a kernel included or not, and you can always go back to another kernel version if you like, but understand that the OS will behave differently with different kernels. For example, if you wish to enable certain functions at the kernel-level, like overclocking, voodoo sound, etc, then you have to flash a customized kernel.
If you flash a custom kernel, then report your bugs to the developer of the kernel, not the ROM, as most bugs are produced by the kernel.
The procedure to flash a kernel is the same as with flashing a ROM, though you need not factory restore your device before installing, although every developer will agree that it is probably best to have what is called a 'clean install', where you would factory reset the device, flash your ROM, and flash your Kernel, and then restore your apps and information. How do you do that you say?
Titanium Backup
Titanium Backup is an app that is pretty self explainitory- it backs up all system files, data (this includes contacts, settings, call logs, etc) user apps, basically saves your state ON TOP of your ROM, where as the CWM Backup (commonly called a 'Nandroid') is the FULL ROM, Titanium Backup will only restore your settings and apps ON TOP of the ROM once installed. Therefore, you can backup all apps, safely factory reset. Install a clean ROM and Kernel together and then restore your data on top of them. This keeps your user files from either being accidentally overwritten or otherwise interfering with the installation of the ROM/Kernel whatever else you wish to flash.
IF YOU SKIPPED AHEAD READ THIS
Titanium Backup can be found on the market for free, if you like it, buy the paid version.
To backup and restore, simply press the settings softkey and choose 'batch' and select the appropriate action with caution. Press the 'RUN' button for the action of your choice and you will be prompted with a checklist of apps and data to run the batch on. Select which files you want or select all if it is your first time using the app and confirm the action. You will need to give Titanium Backup Superuser permission and make sure you have 'Unknown Sources' checked as well as 'Debugging Mode' checked in your settings/applications menu.
Ok, now go back to 'Recovery Mode' section and keep reading..
Also understand that if you are moving from a version that you have backed up in which apps will not be useable in the version you are moving to, the will not work either. For example, if you flash an ICS ROM and then save the ICS-only apps with titanium backup, and then try to move back to honeycomb or gingerbread (if you have a phone like I do) these apps will likely not install or if they do will FC (force close) constantly. Similar things can happen with user data, call logs from one dailer might not be compatible with an older version etc, so expect there to be instances where you have to selectively install apps one at a time to see if it causes bugs, testing the device for buggs, and uninstalling the app/data before proceding with your restore if it does.
Return to Stock
EDIT: While the below represents a review of how we used to unroot, I have now learned that merely flashing the stock ROM provided by Asus on their website will flash the recovery as well, and that there is a minor difference between the recovery img that came on the device stock versus the recovery img that comes loaded in the Asus firmware packages. If nothing else, the graphics are different, but I suspect that there could be other changes as well. To best unroot the device, simply watch and follow the video in the link.
Outdated info;
So, you played around, and you decided it was time to go back stock for that update, or maybe you just liked it better, or you wanted to give it to your grandma but knew Revolver was above her head- whatever the reason, you want to start fresh. The procedure requires you to get the Stock recovery image and a stock ROM. Luckily the stock ROMs are available on Asus' website, the recovery image isn't as easy to find, it is located here;
http://theunlockr.com/2011/11/28/how-to-unroot-and-remove-cwm-recovery-on-asus-transformer/
(Note: The recovery file is not region-specific, therefore it does not matter what version TF101 you have, it is one of the few 'universal' files for this device.
CAUTION: Unrooting with this procedure will only rewrite your system files on the system partition, if you have files located in your root directory that are user-created files that are not part of the system, these files will remain after unrooting, though you will not be able to view them as they are in the root directory, if you root the device again they will be visible. If selling your device or returning for an exchange and you are unrooting it, make sure to manually delete any files/folders that you created in your root directory and do a factory restore with CWM before flashing over your recovery.

Procedure:
Click HERE to watch my UNROOTING How-to video.
There should also be a distinction made here between unrooting and breaking root access, while breaking root access will prevent you from having root access to your device, it does not return your device to stock. For example, deleting your superuser application and su binary files can 'break your root' as it is referred to. Yet, in order to effectively unroot your device, you should return the device to it's 100% stock configuration. If you are giving the tab to your grandma or little sister, breaking root is probably enough. If you want to return the device or sell it on XDA, you should probably return to stock completely.
Now that you have read all of this (hopefully) here is the shortcut you wished you had;
My HOW TO ROOT video (Part one)
So, now you are a BUTTFLIPPIN' PRO, you can root, you can flash recovery mode, ROMs, even Kernels, and you can flash stock files from your SD card so you can unroot and return to stock if you want. What if something goes wrong? What if you want to expand your knowledge?
Well this is what we all fear, this section will attempt to address possible outcomes of bad flashes, corrupt ROM images, bad recovery images, etc. as well as help you diagnose your problem and determine whether you need an RMA or to ask for help in the forum.
[Q] My screen won't come on! Help!
[A] In order to determine what the problem is, first try to power on normally, if that does not work try to power on with the USB device plugged into a PC, if you hear it connect you unfortuntely likely have a screen malfunction. If not, try to enter APX mode and listen for notification of connecting to your PC, if still no notification, try charging your tablet overnight and see if it is over-discharged, mine did this once and scared the CRAP out of me, I thought it was bricked, after 10 minutes of fooing with it a battery warning finally popped onto the screen for 1 second before shutting off again. Repeat the previous steps after 24 hours of charging (if TF does not power on on its' own). If none of these solutions work, try powering on and listening for the camera to 'click', if you do not hear this, then it is very likely you have a brick or malfunctioning device.
[Q] My dock drains very fast..why?
[A] This is a problem with old firmware and certain docks. The docks themselves were manufactured with hardware that prevents the updated firmware from being installed in the dock itself, which results in being unable to change the battery consumption configuration. The dock was originally designed to keep the TF awake so that a quick key press would wake it easily, but this resulted in battery drain, when Asus updated the firmware they realized some docks simply needed to be RMA'd. To test yours;
1. Make sure you are updated to the latest firmware for the dock (in Settings?About Tablet), latest firmware is EP101-0213.
2. In Settings>Screen make sure "MobileDock Battery saving mode" is checked.
3. Press the power button on the TF101 to turn the screen off, then press a key on the keyboard (not the mouse buttons).
If any key wakes the TF, then you have the defective dock and must be RMA'd. However if it does not wake, and you still have severe drain, try to resolve it by shutting off background services and checking to see if drain is bad without the dock as well. If it is still draining, as mine has done previously, contact Asus for an RMA.
[Q] My dock is making a strange squealing sound??
[A] Yes, I received one that did this myself, and returned it to the store I purchased it. As far as I could tell it only presented an annoyance, but others reported the issue and suspected that it might have been connected with some people's battery drain issue, so I returned mine as you probably should as well.
[Q] My screen has light bleeding around the edges..is this common?
[A] Unfortunately, yes, light bleed on these devices is far too common. You can try to return the device and get a better one, depending on the severity of the light bleed, and unfortunately it seems every device has it's quirks, you may end up with one that doesn't have much light bleed but has another problem..
[Q] My case creaks, is this normal?
[A] Yes, unfortunately, the plastic backplate has notches that are supposed to affix into the bezel, and sometimes these come loose. However, some people have reported being able to 'snap' it into place again within the bezel, others had to remove the bezel and backplate partially to resolve the issue- others just ignore it as it is only cosmetic.
[Q] My Transformer won't charge! Help!
[A] There could be a few reasons for this experience- the connector is a proprietary connector, and the wires inside can be easily tangled and snapped according to user experience- to verify that the cable works try plugging the device while powered on into the PC and listen for audio confirmation. If your cable is working, but the tablet doesn't seem to charge, you can try to plug in the dock to see if the led on it lights up (unfortunately the TF unit has no charging indicator except for when powered on). The charging adapter itself sometimes has connection problems inside it, and some users have reported success in simply enclosing the charger in a ziplock bag and placing it in the freezer for several hours. I don't know why this works for some, but it does. If it doesn't for you, however, you may need to order a new power adapter from Asus, or you can make your own here;

[Q] My TF keeps booting and booting but never loads into my ROM..
[A] This is called a 'bootloop', and depending on how far it loads can tell you the severity of the boot loop. First thing to do, is to attempt to boot into recovery. Unless you have an SBK1 tab, this is going to be the only way you will be able to stop this. If not, you have a soft-brick. Eee Pad logo loads and reboots after this, then you have a problem with the ROM itself not wanting to boot (corrupt image, files missing, etc), and usually reflashing your previous ROM without wiping will cure the issue. Sometimes the issue is within the ROM, settings that lock up your device while initializing. If it makes it to the boot animation and reloads, there is a possibility that it is a setting within a kernel if you have a custom kernel installed, try another one, if you aren't running a custom kernel it could be user settings and a factory restore may resolve the issue, and if that fails try another ROM. If the TF will not go into recovery mode and reboots within 5-10 seconds from powering on, you might have a major problem with your system in which case only NVFlash is likely to help.
[Q] I keep getting FC's and bugs..(OR) Do I need to wipe to install...?
[A] Making sure you wipe the correct partitions before you flash new software is vital to making sure it functions properly. This is your necessary wiping procedure, although always best to have a clean install as previously stated;
Nature of the flash| Wipe cache? Wipe Dalvik? Factory Reset?
Clean ROM Flash = YES YES YES
Kernel Flash = YES YES NO
App Pack Flash = YES YES NO
Theme Flash = YES NO NO
ROM Re-flash = NO NO NO
Recovery Flash = NO NO NO
Nandroid Restore = NO NO NO
(Will work on getting this more graphlike after dinner )
Of course always better safe than sorry, and unless you are trying to preserve user apps and data while flashing a kernel or theme then it is always best to reinstall everything after a clean wipe to avoid orphan files and other messy possible errors.
[Q] I can't get into recovery! Help!
[A] The only time you really need to start worrying about not being able to get into recovery is if your ROM also will not load, and vice versa. Since you can simply use the RecoveryInstaller app to fix your broken recovery, similarly if your TF will boot into recovery mode but NOT into the ROM you simply flash (or re-flash) your previous ROM to restore your OS. For this reason, when wishing to update BOTH ROM and recovery, DO NOT FLASH BOTH AT ONCE WITHOUT CONFIRMING THE FIRST FLASH WORKED!
My general rule is to flash my recovery mode first, and then flash my ROM, this is true whether going forward in versions or rolling back to older versions. This way, as soon as you are done flashing and restart (simply holding Volume DOWN as it reboots on its own is enough to initiate recovery mode, be sure to then press Volume UP), you will know if your flash was a success and can rest easy as you flash your ROM, if done the other way around you have to boot into your OS to confirm the flash worked and then reboot back into recovery. If your recovery flash fails, simply allow the OS to load, load recovery installer again and try again.
In the case in which your ROM or recovery will not load, again, your only hope is that you are an SBK1 device and can restore your device via NVFlash.
[Q] Help! My buttons (volume, power) don't work!
[A] Unfortunately this has been discussed quite a bit, sometimes it is related to poor manufacturing, or user damage, or even a poor RMA service. In this case you have only two options- you can try to RMA it, or you can try to tear down the TF101 yourself to try and repair it. It isn't advisable if you can get it repaired under warranty, but if not, you can find discussion with photos of a teardown of the unit here;
http://forum.xda-developers.com/showthread.php?t=1109928
[Q] How do I edit the files in my root directory?
[A] The File Explorer app provided by Asus by design will not allow you to access the root directory, you must use an app, like Root Explorer. In order to change or delete files directly from this app, you will need to make sure the root is mounted as R/W (readable/writeable) as opposed to R/O (Read Only), there will be an option to 'mount R/W' if it is mounted currently as R/O, and vice versa.
[Q] How do I remove Asus' Pre-Installed apps (Bloatware)?
[A]While you can simply delete the app file with your Root Explorer, this may not delete all user data. You could download a tool called Root Uninstaller from the Android Market, or you can use the functions in Titanium Backup to run batch uninstalls, or just 'deselect all' and delete one at a time.
[Q] How do I get back my Asus or Google apps after flashing a modded ROM?
[A]GApps and Asus apps generally are not included with many custom ROMs for copyright reasons, but GApps can be found here;
http://goo-inside.me/gapps/
Asus apps can be found in Gnufabios' package 'Asus Removed Apps' that can be acquired through his Revolver Parts package if you are running that ROM, or can be downloaded here if not;
http://www.gnufabio.com/revolver/dls/
Or you can always make a Titanum Backup of your valued system apps before you flash your ROM. You can then do what I do, find the Titanium Backup folder on your internal and rename it 'TitaniumBackupStockApps' and move it to your SD card, then backup your user apps, rename THAT folder 'TitaniumBackupUserApps' (you may even want to date it or name which ROM it came from, this is your choice), and remove that from your internal memory. You could then do the same with user data, if you decide to do that separately. To flash them back, simply replace the folder and rename it to the 'TitaniumBackup' as it was originally, or, if the folder already exists you can simply copy over the contents, run the batch, then delete the contents and copy the user data contents over as well. This is a great way to keep your apps and data organized and backed up safely. You should make sure this stays up to date and delete old backups after 2 to 3 iterations.
[Q] Can I run Linux?
[A] Yes, look here;
http://forum.xda-developers.com/showthread.php?t=1364095
[Q] How do I install themes?
[A] Depending on the ROM and Launcher you are using, some of the theming options can be built in and accessed in settings menus inside the Android UI (User Interface). However, there are other themes that change files within your root directories and these files will generally need to be installed either via CWM or via ADB. The themes' developer should have clear instructions on installing it.

Nice job Luna.
+1 on the vipermod. That is what I used and it was extremy simple.
ViperMOD..the one thing I have no experience in on this device it seems; I did a crash course, seems it was actually based right off of Nachoroot, just a cleaned up command prompt interface, and interestingly works on TF101 and TF201. Perhaps that is why I never used it- the post is located in the Prime forum section

Hi Luna
I tried to follow the Return to Stock instructions you listed but there seems to be some problems.
I know these problems are not your fault but maybe you know of another alternative which is as easy to follow as well?
I need a WW Version of the packed stock Rom but neither US nor WW are available due to the mediafire problem.
And the recovery is called 8239USrecovery so I assume I can't use it with my WW version?
Return to Stock
So, you played around, and you decided it was time to go back stock for that update, or maybe you just liked it better, or you wanted to give it to your grandma but knew Revolver was above her head- whatever the reason, you want to start fresh. The procedure requires you to get the Stock recovery image and a stock ROM. Luckily the stock ROMs are available on Asus' website, the recovery image isn't as easy to find, it i located here;
http://theunlockr.com/2011/11/28/how...s-transformer/
Place both files on your SD, but make sure the ROM file is in root (they can both be in the root it doesn't matter) and then use CWM to flash the recovery image, then WIPE EVERYTHING before rebooting into recovery mode again to confirm you have stock recovery in place, and allow it to flash stock ROM. Double check that you are unrooted by downloading superuser and installing it and seeing if it allows you root access (it should not).

About Stock Recovery Mode
The stock recovery mode is absolutely required to install official Asus OTA (Over The Air) updates. It can also be used to install (or RE-install if it were) your STOCK ROM (only official, digitally signed files will be accepted by the stock recovery to flash over the firmware, no modded roms will work). The method for doing this is outlined in the link for rolling back your firmware version above but I will summarize;

So theoretically this stock recovery mode will allow us to recover to a stock Asus signed ROM in case the main ROM get damaged? for example if rooting goes wrong or any other reason?
I have an SBK2 TF101, and I don't want to install CWM for the moment but want to have root, and don't want to brick my pad.
Outstanding post. Thanks a lot...

The recovery mode can be used regardless of region or firmware version, and if you are unable to locate the firmware files due to mediafire and megaupload etc. being down, simply retrieve them from Asus' website here;

Yes, if you retain your stock recovery mode then it will be able to flash your firmware in the event that your ROM gets messed up for whatever reason, so long as you use the Stock signed copies of your firmware from Asus (i.e. the official files), recovery mode as stated will only flash official Asus files, they are digitally signed by Asus and without the signature recovery mode will fail.
And to put you at ease, the likelihood of anything going wrong while rooting is much smaller than flashing custom ROMs or recovery mode. Rooting is fairly fail-safe if you follow directions well.

I am asking because, as mentioned earlier, I only need to root for now without going the whole mod thing, because at the moment I am still not convinced that an android tablet suits me, so in case I still don't like it I want to be able to restore the stock ROM without going more into modding CWM and risking a brick.
So, in the case I root then later decide that I want to unroot, it is enough to put the signed stock Asus firmware on the SD card and boot into recovery mode, and it will be unrooted? why is it then that most unrooting guides does this with a special repacked zip file? why not just stock asus zip?
sticky!

First, you should know that if you do not install CWM and flash a custom ROM, you will never actually know what you can do with an android tablet
But to answer about why others use special zips, unrooting with the Asus file actually does not delete anything on your system partition, it will simply rewrite all the system files, if there are other files that are unrelated to the rooting process leftover in your system partition those files will remain after unrooting. That is what the unroot zip files do usually, is they delete everything and reformat the system partition before installing (instead of just overwrite installing) to avoid leaving orphan files. But these orphan files usually do not impact your system (the entire system has been rewritten anyway) and for sake of argument your TF is unrooted, as you no longer have root access. To avoid leaving anything in your system after unrooting you should factory restore and delete all user apps/data with something like titanium backup before installing the stock firmware over your old rooted ROM. I will think of how to add this to the OP to make it more clear.
Basically though, if you unroot you will want to manually remove any files that are in your system partition (root directory) that were not there when you first rooted your TF or flashing the stock ROM will simply leave those and overwrite the other folders/files.
Just to throw something in here about that. Vipermod does have an unroot setting in it's commands.
Or using terminal emulator or adb
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
reboot

I bought a used A500 that was already rooted.

I bought it and it appears to have ICS because the Android version is 4.0.3 but that is all I really know right now. I expect that it was never updated OTA though because the guy I bought it off had it for 2 months and he was not the one who rooted it. I was going to leave it as is because I bought it for my 10 year old daughter...but the camera takes very blurry, kind of grainy looking pictures.
I am not afraid to root because I had a Samsung Fascinate and I loved the custom roms I downloaded to it. It had been over a year since i had the Fascinate so i am a little rusty when it comes to all if this. My problem is not knowing where to start with this A500 because I am unsure what has already been done to it.
The guy who sold it to me said he did a factory restore, but when I ran the check root app it does state that it's rooted and I figured it was because there is a app called superuser on the device. I don't know what kernal it has. I don't know if it has a bootloader and/or the version number. I don't know if it has CWM and/or the version. number.
What is the best way to proceed? By the way, the tablet is very clean with absolutely no scratches anywhere. Not a bad buy for $175 with a leather case...
Setting > About tablet. That should tell you quite a bit of info about it no?
download the acer recovery app , it will tell you what Bootloader you have and what recovery
Thanks for the replies! When I get home I will check. I don't want to brick the thing. I ordered a micro SD today and I will get it in 2 days so there is no hurry for me to proceed. Is it worth it to keep it rooted? Is the OTA ICS good enough? I don't think my daughter cares if the tablet is overclocked but if the roms are much better than stock than I would keep it rooted and then download a preferred rom.
Vintage144, in another post you specified that there is a Acer recovery beta...will I need that or would I just get the one from google play? Also when I find out which version of recovery and bootloader I have...I am not sure what to do with the information. Could AfterOta help me accomplish what I want if my goal is to try and fix her camera issue...either by going back to stock or updating the kernal and rom.
I don't want to seem like a noob but my only rooting experience was with my Fascinate which I did everything from stock. Now that I am not coming from stock, I am unsure where to go with what I have. It's like trying to get to a goal but not sure what step to start at. If I was starting from stock I could follow some of the threads here but it's not stock.
What info will I need to post here to let you guys know what is in my A500? I know that the Android version is 4.0.3 , what else will I need to post?
well the beta copy I believe is at thors tegra forum , but its by euclids brother (thats his name on xda) anyway if you've upgraded your BL it will tell you version you have and might give you accurate Recovery as well, if the device is only for your daughter and she's too young to really do anything I would stick with a stock rom and realistically I would upgrade the boot loader , why be left behind?
Theres no reason to root if you dont plan on doing anything major with it,that being said you wont be able to get a newer Boot Loader or custom recovery without it, and custom recovery is well worth the effort!
You guys are the pros so I will take your advise. I don't mind it being rooted and if there are some really nice roms I expect my daughter would like the different looks...it would seperate hers from others.

Damn auto correct!!!
You're already running an older custom rom...
You have root - your words not mine...
You can download another custom rom, put it on the sd card/ internal memory and reboot into recovery. You need to wipe cache, dalvik cache and do a data wipe(factory reset) after which you can install zip from sd card. Go to the rom zip file you put there and install...
Wait until it boots...
I don't know if you're running the new ICS bootloaders or not.
BEFORE FLASHING - make a nandroid backup. If things go bad then you can go back and restore the tab to before the flash...
It's worth getting your CPUID and keeping it safe somewhere and you might think about installing the ICS bootloaders (I'd do it just to be sure I have them) but thats you're choice...
Good luck...

Probably want to hold off on flashing roms a second.
He's running an HC Bootloader. I'm 99% sure of this. Reason, RA Revamped 3.16 doesn't work with ICS Bootloaders. So you can install an ICS Rom, but, it has to be an ICS Rom for the HC Bootloader. And the performance under HC BL is not near as good as ICS BL.
I would do like UltraMag mentioned as far as install steps and such. It's how we install roms.
Check this thread;
http://forum.xda-developers.com/showthread.php?t=1622425 (steps 1-6)
, and install an unlocked ICS Bootloader and a CWM 7 or 7.2 recovery. Then install one of the Roms made for the ICS Bootloader.
I know AfterOTA will do some of this for you. But this thread gives a good idea of what's going on.
Thanks for your help. I will be getting my micro sd card on Friday. In the mean time I will do a bunch of reading about the things you guys told me to do...again thanks a lot. I really appreciate the help.
I am the kind of person that really wants to know what I am doing...I don't expect all the answers, I just don't want to brick this device.
Forstir9,
Moscow Desire is a great dev on this board, his information about updating the bootloader is dead on. I recommend reading the entire OP in that thread, and then re-read section listed as Automated Flashing Tools, it really helps tremendously if you are a person familiar with root, but not extremely dynamic with making these changes.
I've rooted several BN Nooks and my A500 many many times and love it. I had the Honeylicious ROM that you listed prior to what I'm currently running. KYJ had a great HC ROM with that one! Personal preference currently for me on the ICS ROM is FLEXREAPER from Civato, poster of the referenced article from MD above, you can find that ROM info here: http://forum.xda-developers.com/showpost.php?p=22964651&postcount=1 Lots of cool features and step by step directions, which are what UltraMag69 listed in their post. There are many many different options though and I recommend reviewing several and then settling in on one when you find the one that fits your (or your daughter's) preferences best.
If you enjoy doing this and playing with the tablet your daughter may not keep it and may end up getting something different, because you may have too much fun with it...good luck, have fun, don't be scared to try things and ask questions (after you read first), and most importantly BACKUP BACKUP BACKUP...
Good luck,

Let me get this straight then.
1) boot into recovery and make a nandroid backup.
2) within that backup I should be able to find the CPUID on my sdcard...I will want to write this down and the write it down again somewhere else...out this number on my phone and computer...pretty much don't lose this number.
3) follow steps 1-6 from the link that Moscow Desire posted.
I am going to go with the Flexreaper rom...should I go with the extreme one or is there another Flexreaper rom that isn't extreme?
4) I think the 6 steps above will install a ICS bootloader
5) find and install the newest recovery
I only have 2 questions
How many of these steps does the Afterota app get Rid of?
Should I use the Acer recovery app to install the bootloader and/or the recovery?

First off. Thanks for thinking I am the "God" of the 501". Yeah, I know it pretty well.
Second, Ultramag, is is one of my right hand men. So I suggest you heed his advice well. I always trust his judgement. Am sure he has puled my arse out of the wringer a few times. Well, maybe not, but you get the picture. Some of us on XDA, support each other. That's how it is. I just noticed the bootloader version, And being one who likes flashing experimental code, well, I noticed.
So;
1. ALWAYS make a recovery backup. Then, restore it to make sure it works. (lots of people don't do this and they get fubar'd later).
2. UID. Seriously. Ok, the link on the many ways to get it. You don't want to get it, well... your;e pretty much fubar'd
http://forum.xda-developers.com/showthread.php?t=1624645
3. He has the normal, and one with a kernel you can overclock. Your choice. Really, if you don't OC, then you run the same as the original. Please don't ask me the names of Civatos roms. The extreme will be fine for you. Just don't overclock it if you don't want to. Only difference is the kernel. Not the OS.
4. Yes.
5. For recovery, I would say CWM 1.7.2. Should work for you. 1.7.0 is also ok. Publick recovery is ok too.
6. Never ran After OTA. But hear it is good when you already have ICS.
Forget AcerRecovery. You will already have bootloaders and recovery installed.
MD
Know I'll probably get a bashing out of this but there's a V1.7.3 recovery on the site that must not be named (cough, tegraowners, cough) that supports the Aroma installer - on Thor's ICS rom anyway...
Just thought I'd throw that in too...
I am ready to do a backup...it's asking me what I want to backup...it has a (X) next to the following...
Boot
System
Data
Cache
Flexrom
Is this correct the way it is?
EDIT: ignore this post I didn't see page 2 -_-
Sorry that I didn't post this in Friday...but I really want to thank everyone for their help. It went very easy and it want too much different than my fascinate.
The camera still takes grainy pictures and a few apps has sounds issues but she really likes the rom a lot.
Thanks again for the help.

New Device, System, Operator ?'s

Hi all!
I did try searching, might be too simple...
New to Android, etc...
Windows and Toshiba taught me to always download original files and archive them for later recovery, drivers, etc... to factory recovery years later when needed.
Now with this...
I think I was at JRN84D (4.1) when purchased on vacation, took OTA update to JRO03D (4.1.1).
At Google, ONLY JRO03D is available.
? Should I hunt around to find and archive JRN84D (or ask for someone else's archive PM) or will JRO03D always be THE factory recover baseline for this device?
?If they replace JRO03D with something else, will those always be then considered the factory baseline? (Or should I keep a progression of images?)
?I think since this is flashed, that my OE file (JR84D) is truly gone forever, since JRO03 is flashed 'over' it, and I can never really factory recover to 'out of the box' state - am I right?
(Trying to get my ducks in a row to start trying Mskip's package...)
THANKS
As long as you have the net Mskips tool will download a stock rom and flash it for you anyway

ROM/ DISK Drive devices.Failure rate .
There is a huge difference in A Tablet os then the tradition installation of windows. Windows is a compiled bunch of software running on a Disk drive.. High Failure rate.
Android Tablet phone/ devices. These are firmware running on a non destructible ROM CHIP. if you are totally stock..and never change that. There is a pre made so to speak backup built in.. This will restore your device to its original state.
You can download the latest firmware os / kernel from gogle as i see you have found already. Be SURE you have and know how to use the tools to flash the software in case of a non boot situation.. I would not count on the install tools mentions above.. FASTBOOT ADB AND BOOT-LOADER COMMANDS .... If you really want to learn about android and understand arm devices more . Lots of information with a google search..
So what im saying is a Un rooted tablet have a very low almost near software error rate. (A QUICK RESTORE WILL FIX EASLY)
If you are not root and you mess up your tablet simple fix.
If you root your tablet and install a custom recovery.. Then you need to save the tools to install the recovery the recovery files. The Boot-Loader files and the ROM. YOU are using or want to use.. Could be stock ROM CUSTOM ROM. if you use a custom kernel you need this as well.
You should also first boot into the CUSTOM Recovery MADE A NANDROD BACKUP... This will be your ticket to restore the device quickly and easy.
I know this is alot of vague information but it kinda touches what your asking..
Good luck .. Guys feel free to fill in the blanks and correct my mistakes.. OOPS Erica makes no mistakes right .. hehe
THX all - I've , let's see - unlocked, rooted, flashed a new rom, restored 'factory' rom, unrooted and relocked - whew!
I think there is a real problem with terminology for OE roms - both by users and the OE. My device says factory or factory state in it somewhere - but that is clearly not what it means. It means current factory or something like that - and that it will never be back to the out-of-the-box factory state. Apparently, I can only ever get back to the cleared-of-user, current 'factory' state.
Anyway, I've a recovery method and the current rom stored for the future.
Is there a site that store earlier roms?

[Poll]Should I root My Samsung Galaxy Note 10.1 ?

Should I root My Samsung Galaxy Note 10.1 ?
Model : GT-N8000
Country : Malaysia
BTW will root cause the Tab to become slow ?
Do I need stock recovery to get OTA ?
As always if you have to ask then the answer is no .
You root when apps or mods require root only .
Root voids warranty ..
This is not the Tab forum do not use any firmware or mods from here on a Tab .
Do I need stock recovery to get OTA
Yes stock and original with no root for OTA .

If you are happy with your Note, than it's not necessary.
I rooted mine, because it was still on 4.0.3, and that is the reason for the many bad reviews on the internet.
After upgrading to 4.1.2, it was like a whole new tablet.

So that I will try and root but BTW just asking is HighXXXXXXXX CMW Recovery good or Darkman Recovery Good ?
TWRP is only for stock rom right ?
There are many benefits to root. All the flashable files here require it.
But technically you will void your warranty.
However there are ways to get back to stock and "unroot" so mostly no one will know the difference if you have to return it.
Both recoveries are good, but HighOnAndroid supported a couple ROMs that Darkman didn't, though I'm not sure this is still the case

You will need to flash the HighXXXXXXXX CMW in ODIN to get root and cwm. You can then flash either darkman recovery with CWM, TWRP recovery or stay as is..
TWRP recovery isa modified recovery like the other 2 and requires root to use. If you look around you'll find the stock recovery too.
I root my tab with Darkman Recorvey is easy then I tot . Thx you guys .

Yes! Rooting is the way to go. There are ways around the warranty issues.
My main reason for rooting is for these essential apps:
Titanium Backup
Ad Blocker
Mobile ODIN
Triangle Away
ROM Toolbox Pro
and many more apps that have useful extended capabilities once rooted.
Some Con's of rooting
1) good mobile app no longer works after rooting.
So if u use good mobile for checking corporate emails, rooting device will break this.
2) there will be some overhead for you to upgrade device when any new firmwares are released. If u are a very busy professional, then this is an overhead you can live without.
3) there are and there always will be chances that you may brick your device.
4) I think u legaly void warranty on device by unlocking it. (I am assuming u want to root to load different firmware)
I am not discouraging.. just givin you other side of the coin.

Sorry to bump a three month old thread, but would anyone know whether the Lotus Traveler app used for syncing corporate email and calendar works after rooting? Good is trash, so I'm not surprised it wouldn't work. There's not much of a downside finding out for myself by rooting my Note 10.1 because I intend to keep flying stock on my Note 2; but I thought someone might save me the time and trouble.

For Lotus Traveler - I have no idea. I am unlucky enough to have Lotus Domino for our corporate e-mail and I hate it with a passion.
I have installed and configured Aqua Mail to connect to our Domino server (IMAP) and I can confirm that it works perfectly after rooting. You just need your IT guys to ensure that you have web access enabled. I set mine to check for mail every 15 minutes, if it's more urgent than that then why is it an email anyway.
Rom Noob tips, from a noob, please feel free to correct, add or expand on any points
General rooting options
Titbits
- rooting under normal circumstances shouldnt slow your system, in fact most devs i believe will attempt to make their roms bring out the best performance from that particular tab/phone you may own, throught software optimizations, in cojunction with working as best as it can with your specific hardware, although, sometimes you may have a N8013(american wifi version), the dev may have the n8000(3g version).......n810 is the european wifi version...................weve been mixing and matching rom versions here, i.e. using a n8000 rom on a n8010 hardware, ive done it, as far as i know, no adverse effects, well at least no obvious signs of em
- Usually, the process of flashing a rom will first involve rooting your tablet, and then flashing a recovery, which replaces the official one that may already be on your tab, the official one is usually pretty limited in what you can do, the custom RECOVERY is flashed because it gives you these options, but not limited
-factory reset
used when, flashing new rom, best to use the recovery when ever you wanna factory reset, i dont know if this was a oje of, or just specific to my situation, but ive used the android factory reset on my tf201 asus prime, after having rooted, custom recovery and been running a custom rom for some time, and it soft brick, since thats happenened ive been shy to do it on any android device, which is cool, as the custom recovery is a beatiful thing.......maybe someone can expand on or correct that suspicion
- wipes
cache- wipe your app cache
Davlik - someone gonna have to chime in there
factory/data reset- brings back your android back to its original state, wipes your data, that means, all apps installed, all settings changed
format - allows you to format the different seperate sections of your android rom, example of the different sections would be......kernel, os, sd hardrive ........
nandroid - the best part of a custom recovery in my opinion, the ability to completely back up your rom, settings, apps, homescreens, widgets......essentially, restoring your android EXACTLY where you left off, the few seconds before, it takes to boot into recovery and start the backup procedure..........you can also backup and restore only certain sections of your rom, so you may decide to back up just the kernel, or you may decide to restore, JUST the kernel from a FULL previous backup (that is, all sections backed up, minus, the sd hardrive,
Unless you specifically FORMAT the sd card, it usually wont be touched......id advice caution and reading up, before making a decision to format sd harddrive, with a custom RECOVERY, that may not know the requirements to your android device, i.e. a custom kernel ported from another android device from another company....plus, formatting sd harddrive is not really a thing done all the time, not unless you are thinking about starting from scratch, i mean, REALLY fresh, disclaimer:this would wipe any files you have stored on your android devices, specifically, documents, pics, vids so on so forth
- stock rom
the original android OS shipped with the device
- stock based rom
tweaked stock rom, speed, battery other mods
-CM (CynogenMod)
third party rom, built from the ground up, kinda....there are other different flavors of third party roms, CM is one of them
-when flashing a new rom, it is strongly advised by most devs to wipe cache/davlick and factory reset....before flashing, this helps avoid any conflicts with the previous rom and the new rom......at this point, if you were to reboot, rather then flash the rom, you would have essentially reset the rom to its original state, that means re-entering your wifi, changing settings, installing apps, generally a pain in the ass, if you find your self having to do it to many times in a short period.....titanium backup(root) is your friend, does a good job at backing up your apps and wifi.....havent figured out how to backup the settings i change in the android setting
https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup
-quick boot
https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot
This free app, is a life saver when your new rom doesnt give you the option to reboot into your recovery, sometime found in hold power button/restart/recovery.......just more quicker then the manual way......especially when your having to google up the hardware method because you've not done it in a while and forgotten......which i believe is power off/hold volume down key/then press hold power button/wait for samsung logo/then let go of all buttons and reapettedly press volume up key untill the recovery shows up.......if you end up in DOWNLOAD mode, hold power to switch off, and repeat the process, changing the volume key, its one or the other, one takes you to the recovery, the other to download mode......so just reverse the volume keys, same method, just up instead of down
- supersu/superuser
installable app, that hands out root permission to apps that ask for root, if you dont expresly give persmision, using a supersu app, the app asking for root permission most likely will not work.... .....this app is installed as part of the rooting process
- afwall+ (free)
third party wifi/3g firewall, requires root........allows you to control what apps are able to use your wif/3g......i think its a passive firwall, as in, it uses very little of your resources, in the way it operates
https://play.google.com/store/apps/details?id=dev.ukanth.ufirewall
- rom flashing
sometimes, if you have already flashed a custom rom, and the dev has released the next version of his custom rom, as long as no drastic changes have been made between the two versions, you are able to flash the new version over the old version, keeping all your settings/apps/homescreen/widgets.......although a cache and davlik wipe is usually suggested if doing so
ive forgotten half of what i was originally going to write, so ill just leave it there before i rack my brains .......goodluck whatever you decide
Yes :good:
if it was me?
yea i would do it. it brings life to an old tablet. the 80XX tablets were abandoned by samsung. there are custom roms for Oreo the latest Android OS for N8000. i have a 8020 but no custom roms at the moment.
Good been waiting a whole 5 years for a reply .

[Q] Can't update after deleting stock apps

I've been trying to update from 4.1.2 to 4.2.2, but I deleted some stock apps and now the update is failing. I've tried flashing it manually and OTA, and various other things, but nothing has helped so far. Has anyone else had this problem?
The OTAs are for use with [size=+2]unmodified[/size] factory ROMs.

I figured that out when I tried to update. I can't flash it either, so your post doesn't really help.

My post tells you that you have the wrong expectation about what OTAs are capable of... and that you are probably the 200'th dude to come in here and say
"Wahhh! The OTA doesn't work on my heavily modified stock ROM!".
If you want it to work without exerting any mental effort, return the /system, boot, and recovery partitions back to 100% pure stock corresponding to whatever release your original ROM was based upon, and run the update. Then re-flash your recovery and re-perform all your /system mods, starting with a flash of the same root kit you started with.
Note that the the update you are contemplating also includes a bootloader update - performed the safest way possible (signature checking performed by the existing boot loader). Doing it the manual way (via fastboot) is quite dangerous, even for experts. If you have a 3g version there is also a radio update which also should not be attempted in any other way than via a pure stock OTA install including use of a stock recovery.
Make a full Nandroid backup before you begin anything - and get a copy of that backup off of the tablet as well as a failsafe measure. If you screw things up moving forward, at least you will be able to start over from where you are right now.
If you have been operating using best practices, you should already have a nandroid backup of the pure-stock /system & boot images. TWRP allows you selectively restore individual partitions. Few users seem to know how to actually make a backup of stock recovery partitions, but you can get that out of oldblue910's archive site - find the link in the OTA thread.
good luck

He's telling you the plain and simple truth. Want the OTA- as it stands, you're out of luck. Either return to stock and then flash the OTA, or flash the 4.2.2 factory image. That's it. Nothing more. That anyone even bothered to answer this uselessly redundant thread is a miracle in and of itself.
