Nandroid backup question

i just flashed a rom and forgot to backup nandroid.
but i backed it up straight away after flashing it , will it be ok?
also how does all this nandroid backup thing work what does it really do,
last time i flashed a rom i still got that backed up if it will be any use.
thanks

A Nandroid backup backs up the entire state of your phone apart from its SD card. You should do one when you have a fully working (and rootable) phone, so that if you screw up flashing it in future you can get back to a working phone with it set up how it was before.
It's not enough just to do the backup, you need to ensure that you can restore from it too. I had to do a restore recently and realised I couldn't use fastboot because I didn't have the right SPL (part of the bootloader) installed. Luckily the recovery image I had let me manipulate it via adb etc. I learned a lot of things the hard way and I suspect I came very close to having a bricked phone.

I don't understand..hopefully I don't mess up my phone, when do I have to restore.nandroid

When flashing a ROM goes wrong (usually unlikely), you can end up with a phone that won't boot. If you do a nandroid backup before you Flash, you have a backup of your entire phone's state before you flashed. There are ways to restore Nandroid backups (or flash other images) even if your phone won't boot normally. You really have to research this and make sure you have everything right before you flash any ROM.
If you don't understand these concepts, you probably shouldn't be flashing ROMs. Just use the official updater provided by HTC in your country.

how can i restore nandroid then if my phone gets messed up thats the main question

Google is your friend. Seriously, there are thousands of resources on this around the web - frankly if you are not willing to do the research into this, just don't flash any ROMs. Doing so is only for technically minded people who know how it all works or are willing to go off and learn about it thoroughly. It doesn't sound like that is you.
This stuff isn't easy, for the same reason flying a 747 isn't easy: it shouldn't be attempted by novices.
I can't just explain it in a couple of sentences.

Can someone help me with this whole root business?

Hey guys, got my mytouch 4g on opening day and I loveeeee every part of it. Coming from an unlocked iphone. I've been reading about flashing roms, kernels, visionary, terminal, and things like that and I have NO idea what any of those mean nor what to do. I really hate the bloatware that comes on my phone and I'd love to learn everything behind rooting. I've been reading around but I can't really seem to understand this stuff!
any help would be appreciated,
thank you

Ok to flash a rom you first need to root your phone, to root your phone follow this very simple guide: http://forum.xda-developers.com/showthread.php?t=858021
then when you reach the flashing portion of that tutorial download the iced glacier rom from: http://forum.xda-developers.com/showthread.php?t=844594, then flash it by following the previously mentioned tutorial.
the iced glacier rom is pretty much the same as the default rom that came with the phone, without all the bloatware plus a few aesthetic differences.
enjoy

Okay I'll help you out. Flashing roms is like upgrading from 3.x firmware in iphone, to 4.0. Different roms offer different things. Ex-iced glacier rom. It is still stock rom but without the bloatware that T-Mobile put in. So each rom offer different things and different features if you will. The cyanogenmod rom is highly sought because of its stock froyo. Froyo is just the os. The mytouch has froyo but it has espresso instead of stock. Espresso with sense ui (mytouch 4g) allows things like automatic speakerphone if you put your phone face down while on a call. Little features like that are what make different os desirable. Keep in mind that sense ui slows down phone and can make buggy.
Terminal. Terminal emulator is like command prompt for windows.you can have your phone perform certain functions or change files through terminal emulator. Like if you downloaded a file and you wanted it to run through terminal emulator, all ud have to do is type in the path, then the file, and it will do its thing. Kind of like when you jailbreak an iphone and wanna change the Alpine and root login since its the default username, you would have to use terminal (assuming you have) I too came from iphone world.

Visionary allows you to "jailbreak" your android phone. You can customize it greatly like the iPhone should you have the right files and edit the right folders. Visionary gives you the administrator access you need to write to the actual system on the phone allowing you to do anything to your phone.

And mods. Mods are moderators in xda. They regulate forums which I'm sure you know. These types of topics go into "general" or "Q&A" forums. Android development gets filled with software, mods, roms, anything that will progress the development of the phone, not questions. Just letting you know for future references as the moderator will probably tell you as well

First, if you have questions (usually thoughts starting with who, what,where, when, why or how) they should be posted in the Q&A section, and I'm sure when the mod logs in it will be moved.
Second, there are at least 4 guides in this section outlining how to root. If you're trying to follow one of the particular guides and have a question do NOT start a new thread, ask your question in the guide and the OP will often answer your question or work with you (especially grankin01 he's really good about it). Also if the person who wrote the guide is busy the community is generally willing to help you with your issues as well.
Third, if you don't want to flash a custom rom and are just concerned with getting rid of bloat, you can (after following a rooting guide and attaining S-OFF) install Titanium Backup. Titanium Backup will allow you to uninstall system applications. I used it to remove about 15 programs Tmo put on there that I don't want/need (ie. game demos, demo video, etc)
Fourth, I'm not trying to be a ****. just trying to show you the error of your ways. I realize you're pretty new so welcome to the community.

Kernel = the core of an operating system. Android runs linux so it's referring to the linux kernel within the operating system. Different kernels are compiled with different options making them able to act differently at a deep level within the operating system. (ie. allowing overclocking)
nandroid = a snapshot of your system essentially. It allows you to back the system up to a precise period in time. This is done through the system's recovery, and is highly encouraged to be done before you take any steps which could cripple your phone (ie. flashing a new rom)
Titanium Backup = A program on market which allows for the removal of protected system applications. You can also make backups of individual applications (recommended before removing)

no worries man I totally understand! I'll make sure to post in author's threads as well thanks. thing is when I see people with their sigs saying kernel and rom and backup I get so confused

It's cool man none of us here knows everything... in the future though consulting google may answer all your questions. BUT if it doesn't feel free to ask away. we just ask that it's posted in the correct section to avoid clutter.

spazmenos ... please be very very careful. I'm sure you're doing the right things by asking lots of questions (and you should!) but I'd be worried that you would turn your phone into a very expensive paperweight. If you have any friends IRL that have root-ed android phones before, perhaps you could sit with them and go through it?

Nandroid is a backup of EVERYTHING. System configuration, call logs, text messages, everything. Say you flash a rom, rom causes problems, nandroid brings everything back to the way it was, providing you can get into recovery mode that is. Recovery mode lets you swap out roms ie. Flashing
Titanium backup is the single most needed app. You can do a backup of just about any app. You can delete apps as well. You don't want bloatware? Titanium backup is the app to do it. Before you delete ANYTHING nandroid backup. To do this download rom manager. Must be rooted first. Click on flash recovery, HTC mytouch 4g. Then make a backup of current rom. To see if it worked, click on reboot into recovery. If you see a bunch if options your good. If you see a red triangle, reflash clockwork. After you see the options they will have fastboot, recovery, image circ, etc. Recovery is where all the magic happens

Please post questions in Q&A section. Thank you

do you have to have perma-root to make a nandroid backup? I ran visionar and then tried to make a nandroid of the current OS in clockwork mod, and it said SU wasn't detected?
EDIT: I had to root it like three times with visionary, but it seems to have worked now.

As always if you have to ask then the answer is no .
You root when apps or mods require root only .
Root voids warranty ..

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.

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 .

General Noob Root and ROM update Questions

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

Everything!

This is the question that pisses me off every time I see it. Not because the OP asked it,,,but because no one ever really gives a good answer. Rather they give what they do. There are many devs out there who spend a crap load of time making TWRP and it would just be nice if they spoke up and ended this debate. Is it system_images, vendor_image, boot, and data? Some say no Vendor_image because that causes problems. Others say backup everything,,,well why backup everything and take up all that space if you dont need to? I backed up everything and got stuck in a bootloop when I restored. I have been doing android since day one and never seen so many answers to one question. Can just one TWRP dev speak up and give us a definitive answer, or do they not know as well?

This is the question that pisses me off every time I see it. Not because the OP asked it,,,but because no one ever really gives a good answer. Rather they give what they do. There are many devs out there who spend a crap load of time making TWRP and it would just be nice if they spoke up and ended this debate. Is it system_images, vendor_image, boot, and data? Some say no Vendor_image because that causes problems. Others say backup everything,,,well why backup everything and take up all that space if you dont need to? I backed up everything and got stuck in a bootloop when I restored. I have been doing android since day one and never seen so many answers to one question. Can just one TWRP dev speak up and give us a definitive answer, or do they not know as well?

This X 1,000!
I've made different backups checking off different things to back up and I'm terrified of having to restore something! Let's just say I'm extra careful of any mod I flash in case I fu-- something up! Haven't had to restore a backup yet and will be shaking when I have to. I have read so much about it, but there is no clear answer and much of it is confusing. And maybe it's the blond girl in me but I remain confused about the A and B partitions - something else I need to read up on.
Wish TWRP devs would have an official message on what to back up and restore! :good:

exactly right! Plus I LOVE the people who say well just back up what they do and it was a fluke that it worked for them. I am like you now, I am very careful what mods I use because I know I will have to start over from scratch and redo my phone. For me I just use TWRP for flashing zips now thats all.
