Quick question on the guides to root the N7

I just got an N7 32GB tablet, very nice. I plan on rooting this device. Mine still on 4.2.1. What guide you guys recommend, both seem good so I'm undecided.
Thanks

Do you know how to use adb/fastboot ? if you know you can use that to easily root the N7.
Here's the link on how to use adb/fastboot to unlock and root the Nexus 7.
If not, then use this toolkit by following the link below:
http://forum.xda-developers.com/showthread.php?t=1766475
Download the program and install it.
After that, watch this tutorial first once and then start rooting with the toolkit.

IMPORTANT NOTE: You must unlock your Nexus 7's bootloader in order to proceed with the rooting process. As a result, everything in your tablet will be erased. So backup what you can and put it back later.

I would recommend using adb fast boot method, it is very simple if you follows it correctly, I will give you full instructions on how to unlock boot loader and root
ALL DATA WILL BE LOST , BACKUP EVERYTHING
I RECOMMEND USING TWRP CUSTOM RECOVERY
Getting started
In order to root Android 4.2 the following three requirements must be satisfied beforehand:
The Android SDK, which you can download from Google Developers
A custom recovery like ClockworkMod (CWM) or Team Win Recovery Project (TWRP)
SuperSU, which you can download from CF-Root
There are no major differences between the two, but TWRP is more touch-oriented thanks to larger buttons. CWM is also available in a touch-compatible variant, but it has much smaller buttons. It's a matter of personal preference between the two though, but you have to choose one.
Before starting the process I urge you to perform a backup, as all data might be lost afterwards. You can copy the contents of the SD card to a safe external location such as cloud storage service or computer hard drive.
Setting the Stage
The first step that needs to be performed after all the files are downloaded is to install the Android SDK. Afterwards open the Android SDK Manager and select the following two items:
Android SDK Platform-tools -- it contains the required programs to install Android 4.2 Jelly Bean
Google USB Driver -- it contains the necessary drivers for the Nexus device
Then you should create a folder in an easily accessible location within the command line. In this example I will use a folder named "Root" in my C:\ drive in Windows. The path name will therefore be: "C:\Root".
From the folder where Android SDK Platform-tools is installed (in my case it is "C:\Program Files x86)\Android\android-sdk\platform-tools") copy the following files to the previously created "Root" folder:
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
fastboot.exe
The following files must also be copied to the "Root" folder:
CWM-SuperSU-v0.97.zip -- SuperSU file
The custom recovery that you previously downloaded for your specific device (please see below)
For my 8 GB nexus 7 wifi(codename "grouper") I will use TWRP with the name "openrecovery-twrp-2.3.1.0-grouper.img".
You can easily find the codename for your devoice by looking into Google
The custom recovery file differs for each device, please make sure you download the correct file
In order to make the process smoother for instance the SuperSU file can be renamed to "root.zip" and the custom recovery to "customrecovery.zip". It's a matter of convenience, but for accuracy I will stick to the original naming for this guide.
If the previous steps are completed you must have the following six files in your "Root" folder:
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
fastboot.exe
CWM-SuperSU-v0.97.zip -- SuperSU file
The custom recovery. In my case it is "openrecovery-twrp-2.3.1.0-grouper.img"
From there, you can proceed to install the drivers for "fastboot mode". To install them, follow these steps:
Power off your Nexus device.
Press and hold Volume Up and Volume Down then press and hold the Power button; the device will now enter "fastboot mode".
Go to Device Manager (Computer -> Properties -> Device Manager in Windows 7/8) and identify the device; for me it shows up as Android 1.0.
Right click Android 1.0 and select "Update Driver Software," then select "Browse my computer for driver software".
Select "Let me pick from a list of device drivers on my computer," then click "Next".
From "Have Disk..." option go to the folder where you have Google USB Driver installed (for me it's "C:\Program Files .(x86)\Android\android-sdk\extras\google\usb_driver") and select "android_winusb.inf".
Out of the three options select "Android ADB Interface" and validate any future warning window to install the driver.
Final preparations
Everything is prepared in order to start the installation process, but in order to do so a command window must be opened. Windows Key + R opens "Run"; type in "cmd" and the command window appears. Typing "cd C:\Root" and pressing Enter sets the "Root" folder as the working directory. Pressing the Shift key and right clicking inside the "Root" folder will also deliver the same result.
The device must be turned on in "fastboot mode" which I have explained at step no.2 during the driver installation process, and obviously plugged-in to the computer. You then have to type in the following commands while in "fastboot mode":
fastboot devices -- this is just for verification purposes; if there is no listed device then the drivers have been improperly installed and steps 1 through 7 must be redone.
fastboot oem unlock -> you have to accept the prompt in order to continue -- this command will unlock the bootloader, but it will also erase the data on the device which is why a backup is necessary.
fastboot reboot-bootloader -- this will reboot the bootloader.
fastboot flash recovery openrecovery-twrp-2.3.1.0-grouper.img -- this will flash the custom recovery --please use the specific file and name for your particular Nexus device!
fastboot erase cache -- this will erase the cache -- might not be necessary but it's just as a precaution.
fastboot reboot -- this will reboot the device.
After Android 4.2 is loaded and running the SuperSU file must be copied from the "Root" folder to the internal storage (shows up in Windows Explorer as a Nexus device). A simple copy and paste will do the trick here.
Then you have to power off the Nexus device and enter "fastboot mode" again. Use the Volume Up and Volume Down keys to navigate until you can select "Recovery Mode". After the power button is pressed the device will reboot in the new custom recovery.
Rooting your Nexus device
If you have ClockworkMod installed, you have to perform the following steps:
Select "install zip from sdcard"
Select "choose zip from sdcard"
Select "0" (zero) folder
Select "CWM-SuperSU-v0.97.zip"
Select "Yes - Install CWM-SuperSU-v0.97.zip"
Select "Go Back"
Select "reboot system now"
If you have Team Win Recovery Project installed, you have to perform the following steps:
Press "Install".\
Select "CWM-SuperSU-v0.97.zip" -- for me it's in the "0" (zero) folder
Swipe to confirm flash
Press "Wipe cache/dalvik" (just as a precaution)
Swipe to wipe
Press "Reboot System"
After Android 4.2 loads your device can run apps with elevated privileges (meaning it's rooted). A SuperSU app is installed in order to allow root requests, so please use your judgement on which apps you grant access.
If you experiences any problem, please reply and I will look into it.

Way to wordy and not easy to follow
Basically:
Boot into recovery (yes i know you don't properly have one)
Get Android SDK from HERE
Once downloaded/installed.
Navigate to the "Platform-tools" folder, where you should see ADB/FASTBOOT
Hold shift, right click and "open command prompt here"
type fastboot devices
(if your device is listed, move on)
Unlock your bootloader
type fastboot oem unlock
Download THIS(supersu)
Download TWRP from HERE
Place the SuperSU download file on your SD CARD (Nexus has a virtual SD, place it there)
Place the recovery in the "Platform-tools" folder with your ADB/FASTBOOT files.
Reboot to fastboot again (Power and volume down)
fastboot devices
if listed continue:
fastboot flash recovery openrecovery-twrp-2.4.1.0-grouper.img
Reboot back into recovery (which should now be twrp) (POWER AND VOLUME DOWN)
Then from TWRP menu choose "Install"
Find the 2 files you downloaded and placed on SD card
Install them using TWRP.
Reboot
Profit.

Well... I liked it... for a guy with only 2 posts to his/her name to explain (perhaps in TOO much detail) how to root takes b**ls:!
Keep it up, naman14... but be a little more judicious in what you include (and choose to exclude) in your walkthrou's.
Writing instructions is art in itself... and requires practice. Succinct and pithy is the way to go.

Thank you all, the last thing i ever rooted was my sprint htc hero a yr or so ago

Updating and Rooting Android 4.3

When I tried to update my rooted Nexus 7 under 4.2.2 through the 4.3 OTA, I ran into an infinite booting loop, blocking at the colored cross.
But I managed to get through with a manual 4.3 update and another 'personal' rooting procedure.
Here are the steps I used to exit that loop, reinstall the official Android 4.3 and root the Nexus 7; I believe they could also be applied to a Nexus 4 or Nexus 10:
1) Downloaded the Official Android 4.3 from Google servers on my laptop: https://developers.google.com/android/nexus/images
2) Uncompressed the chosen file (.tgz) with a tool like WinRar
3) Updated Android SDK with SDK Manager; If you don't have it: http://developer.android.com/sdk/index.html with Java JDK: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
4) Told my system where the fastboot command was located: Added %SYSTEMROOT%\System32;C:\Program Files\Android Developer Tools\adt-bundle-windows-x86_64\sdk\platform-tools; to the PATH (you may need to adapt this to your computer Operating System - mine is Windows 7 64 bits): Computer -> Properties -> Advanced System Settings -> Environment Variables -> System Variables -> Path -> Edit -> your path at the end after an added delimiter character: ;
5) Opened a command prompt and changed the directory to where I decompressed the .tgz Google file
6) Connected the Nexus to the USB port on the laptop and kept it connected until the end of this procedure
7) Nexus was stuck on the colored cross sign
8) Powered it off
9) Booted on the Bootloader: Powered on while pressing volume key down
10) Chose Recovery mode: volume key down then power
11) Stuck on 'no command': that was the tricky part
12) Exited 'no command': powered while pressing volume up for a few seconds, then quickly released both keys. You may need to do this a few times before succeeding.
13) Checked the connectivity with the Nexus: "fastboot devices" from the command prompt. You should see your device id.
14) Flashed Android 4.3 on the Nexus: launched "flash-all.bat"
15) Rooted the Nexus by following the last 2 steps of my Universal Rooting Procedure: http://forum.xda-developers.com/showthread.php?t=2184233:
step 9) CWM Recovery: located here: http://www.clockworkmod.com/rommanager
step 10) Rooting Step: SuperSU, UPDATE-SuperSU-v1.45.zip is located here: http://download.chainfire.eu/343/SuperSU/UPDATE-SuperSU-v1.45.zip
And that's it!

How to dual boot: ONLY FOR GALAXY S2
Warning: This procedure doesn't really work anymore. It only works with Android 4 (Ice Cream Sandwich) and Siyah Kernel v 5.0.1. Later versions of either won't work. Consider this guide archived, and use it at your own risk.
If you want to test B2G from time to time but continue using Android as your main OS and you have a Samsung Galaxy S2, you can choose to install B2G in a separate partition (which is already present on the phone) and choose where to boot into when your device starts.
Prerequisites
In order to dual boot Android and B2G, you have to meet these prerequisites:
You have to have built B2G for the Galaxy S2
You have to download the Siyah kernel v. 5.0.1 for the Galaxy S2
You need the tool simg2img, that you get automatically if you build B2G following the guide on MDN
You need the heimdall tool, best if version 1.3.1 as you may encounter problems with version 1.3.2
One-time operations
There are several operations to do in order to get a working dual boot. The following ones need to be done the first time only.
In order to use heimdall without requiring root access, you should create a file called android.rules (the portion of the name before the .rules extension is arbitrary) and place it in /etc/udev/rules.d. The file should contain a line line the following:
Code:
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666"
In order to activate this rule, you should restart udev:
Code:
sudo service udev restart
and then unplug and replug in the phone. The above rule will also allow adb to access the SGS2 without requiring root privlidges.
Flashing the Siyah kernel
The Siyah kernel is mandatory for the dual boot, because it is this kernel that manages it. Once you have downloaded and decompressed the tar file, you'll be left with a file named zImage. In order to flash it on your phone you have to follow these steps:
Switch off your phone
Reboot in download mode (press together volume down + home + power buttons and then, when asked, volume up button)
Use heimdall to flash the kernel with the following command (your phone needs to be connected to your PC):
heimdall flash --kernel /path/to/zImage
Once the kernel is flashed the phone will reboot.
Preparing the B2G rom environment
Once you've installed the Siyah kernel, it's time to use its functions to prepare the environment to install your B2G image in the secondary partition. Follow these steps:
Switch off your phone
Reboot in recovery mode (press together volume up + home + power buttons)
In the CWMR Touch interface, go to dual-boot options -> Wipe 2ndROM data/cache -> Yes - Wipe. This operation will take some time
Once the operation is finished, select Go Back and then reboot system now to reboot your phone. If you check, inside the internal SD card of your phone you'll now have a .secondrom directory with inside two files named cache.img and data.img.
B2G update operations
The following operations need to be done every time you build a new version of B2G.
In order to simplify command line instructions, it's advised to copy all needed files in a same folder of your choice. These are the files that need to be copied inside the folder:
Code:
simg2img, found in B2G/out/target/product/galaxys2/system/bin/
system.img, found in B2G/out/target/product/galaxys2/
userdata.img, found in B2G/out/target/product/galaxys2/
Once you have all the files in one place, do the following:
Create a data.img file out of the sparse file userdata.img. You can do it with the following command:
Code:
simg2img userdata.img data.img
Put the data.img file on your phone's .secondrom folder. You can do this either by enabling file storage mode on your phone and connecting it to your PC or, if you have USB Debug active, you can use adb:
adb push /path/to/data.img /sdcard/.secondrom/data.img
Switch off your phone
Reboot in download mode (press together volume down + home + power buttons and then, when asked, volume up button)
Use heimdall to flash B2G firmware inside the second partition:
heimdall flash --hidden system.img
Once the flash is finished, your phone will reboot and at boot time you can boot into your second rom (the B2G one) by pressing the home button during the bootloader countdown. If everything has gone right, once you've finished booting B2G you'll have a black screen on your phone. You now have to install Gaia.
Note: Depending on how you want to test B2G, you may not want to put a new data.img file on the phone every time you update B2G, as it will wipe all of your preferences, installed applications and in general pretty much everything you've done while using B2G.
Boot operations
The following operations need to be done every time you boot inside B2G.
Unfortunately, there's no simple way to put Gaia inside the system.img B2G image, and it get lost when you switch off your phone, so you'll need to install Gaia again every time you boot inside B2G. To install Gaia, type the following on a console after you've booted your phone inside B2G (so you have a black screen) and have connected your phone to your PC:
cd B2G/gaia
GAIA_DOMAIN=foo.org make install-gaia
After the upload of Gaia is completed, on your phone's screen the B2G interface will appear.

trying to bring my brothers A500 to life in 2019

Hey together,
I really hope someone out there is still using a A500 Tablet and may be able to help me fix a weird issue i encounter on every ROM i tried so far.
I installed the ROMs mentioned in this Thread: https://forum.xda-developers.com/iconia-a500/general/2018-a500-upgrade-threaddownloads-to-t3832293
And all of them come with the Same Problem for me.
If i try to open the Google PlayStore or something else that wants me to login into a Google Account it just says: "There was a problem communicating with Google Servers" "Try again later"
anyone knows of this issue ? All the fixes several Google searches gave me did not help to fix that issue for me on any of the ROMs.
help would be highly appreciated
kind regards
Finn

Hi,
have you read the tips? It says:
"- Google play will not work right if you do not format your data partition to f2fs. (You can do this in recovery)"
Have you tried it?

First my thanks to the forum key members for providing answers to queries and to all the key contributors of SW/ROMS in this forum. I followed the procedures from this forum to Flash / upgrade my Acer Iconia A500 on 4.0.3 ICS that was sitting in a trunk for the last few years. Summary of steps I tried out.
STEP 1: Install the Acer device drivers listed in the links in this forum on your Laptop/Computer even if by default your Windows 10 OS (assuming you are on Win10 like me) is able to recognize the A500 connected to the USB port.
USB_Acer_1.00.0524_A30HA31HA32H_A.ZIP
STEP 2: ROOTING the Acer A500.
1. The tablet should be already upgraded to stock ICS for A50x (or stock ICS A10x/A510 for other tablets).
2. On a tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch ON. If you do not see this menu, then click 7 times of the Android Build No. listed under settings and come back to the menu above to enable USB Debugging.
3. Connect the tablet to the computer (Before connection it is recommended to update the driver for a tablet from here: A10x, A50x, A510).
4. Since most of the discussions regarding flashing A500 were from 2011, the earlier Gingerbreak method for rooting did not work.
I downloaded the following file from this forum to root my tablet.
ICS_rooting_A10x_A5xx.zip
5. Open the directory with the unpacked archive. Execute file: for windows - runit-win.bat; for Linux - runit-linux.sh.
The root is received!
Note: The McAfee Antivirus software started tagging a file 'mempodroid' within this ZIP file Tools folder as a virus or malicious file. This rooting method uses the 'mempodroid' exploit which is detected as a VIRUS by McAfee and Qurantined. So restore from Qurantine and check list of files are still present in the folder. If not verify 8+8 files in folders again.
As per inputs in this forum, I restored the files quarantined and then suppressed McAfee SW for the duration of my upgrade activities on my laptop and was able to successfully extract all the files in the ZIP file to a local folder on the laptop. This ZIP file has adb and fastboot - two key programs useful for rooting your A500 apart from SU or superuser base file used in step 2. The file to run is the BAT file runit-win.bat if you are on windows. At the end of this step your tablet should be rooted. You may check by installing the RootCheck app from Google Playstore.
Step1a: Install a File Manager app from the Google playstore. This will help you extract the CPU ID and convert it with the SBK tool to get the SBK number/string. important steps SBK tool was available in file - SBCalc_v1.1.ZIP available in this forum.
STEP 2b: SUPERUSER and SUPERSU installation
1. Install SuperUser.apk first.. (IMP - Its available in this forum. Its like a base version for superSU to install over. If you do not install SuperUser.apk, then each time you try installing SuperSU, you would get an error message about a SU file being incompatible.)
2. Then install an older version of SuperSU downloaded from the website - filename -> eu.chainfire.supersu_v2.65-265.ZIP . Newer versions will not work. U got to install an older version as new version seems to be a paid SW.
3. Next Open SuperSU app on your tablet and let it update itself a couple of times each time opening and closing the app after the upgrade.
4. Remove SuperUser.apk file as now its no longer needed.
5. Now that you have ROOT access and SuperUSer access
6. Install Titanium Backup. File name in this forum- update-recovery-TWRP-rev2.0-beta4.ZIP . This will help you to flash/upgrade ROM software on your tablet.
Twrp 2.8:
http://www.mediafire.com/file/e7wpny5f39vw3pc/update-recovery-TWRP-rev2.0-beta4.zip/file
Compressed Archive (.ZIP)
File size: 4.91MB
Uploaded: 2018-08-14 21:40:26
https://www.mediafire.com/download/e7wpny5f39vw3pc
STEP 3: Install an Unlocked Bootloader i.e. unlocked bootloader Skrillax v9 - file name in this forum BabSector.rar or A500-Bootloader-Nvflash.ZIP
Once you have reached this step, you now have the basic tools needed for the final ROM upgrade of the tablet.
I did get error message after the reboots that happened after Unlocking the Bootloader. Someting about a LNX partition not being okay or some such msg. Each time I just WIPED the Cache and selected similar options to wipe System, Data, User, Dhelvic cache (spelling incorrect) etc. Since you have not installed the final OS or ROM for your tablet yet, no harm in deleting these partition data. Actually its recommended to wipe, format in f2f formats etc. all of which is possible using the TWRP Recovery software you installed in step 2. Choose Recovery menu option each time the tablet boots or gives errors.... using the volume rocket and power buttons. More info -> Go through this thread and install unlocked bootloader.

Step 6: Download a rom and flash in twrp
This tutorial is based of

Bootloader unlock files:
http://www.mediafire.com/file/o7m2ouwo6zuod4d/A500-Bootloader-Nvflash.zip/file
STEP 4. Downloaded file omni-4.4.4-20150210-a500-IconiaHD.ZIP as I was not sure version omni 5.1.1 was as stable as Omni4.4.4 reading all the threads in this forum.
First rename the downloaded OMNIROM file as update.zip .
OmniRom 4.4.4
http://www.mediafire.com/file/ghd72j3g618kk9g/OMNIROM-5.1.1-Tegraowners_ROM_v13t2.zip/file
File size: 244.66MB

STEP 5: Install another tool adb_fast.ZIP. This tool is also available in this forum.
Note:You need to copy the update.zip file to your computers folder where this tool adb_fast is installed. In mine it was C:\Program files (x86)\Minimal ADB and Fastboot folder. This adb_fast file creates an application shortcut on your computer desktop. Clicking on the short cut launches adb and fast boot programs I mentioned at the beginning.
STEP 6: Copy the file to the SD card (16GB) of your tablet.
Run the adb_fast tool from your desktop shortcut. This will open a Command Prompt type black screen window where you can enter the code as given below. Note you may need to see how your SD card is listed in a file manager in your computer
Code:
adb push update.zip /mnt/sdcard/update.zip --- NOTE: this creates mnt folder on internal storage and I had to then move the file using TWRP recovery tool installed in step 2, to the SD card.
adb push < ------- is the push command.
rom.zip < ------- is the name of the Rom zip file.
/sdcard < ------- is the location your pushing the Rom to.
E.) Reboot tablet with Power+Down Arrow i.e. This will start the Upgrade process for the tablet to OMNIROM 4.4.4
-- Power Button + UP VOLUME pressed... then release Power button after LED lights.
-- System will boot to commmand prompt
STEP 7: Install GAPPS using pico gapps short version and Wipe Data/Factory reset ----------------?>and wipe cache partition?
Reboot after 1st reboot
G.) https://opengapps.org/ to install a minimal version of Google Apps on the tablet.
File name -> pa_gapps-modular-mini-4.4.4-20150410-signed.ZIP
Root tablet again and install SuperSU if you need it
other info.
You can use TWRP to flash the OmniROM on the tablet or you can use the following in worst case senario to do the same.
Code:
fastboot devices
fastboot flash update.zip -- check if syntax is ok from threads in this forum
fastboot reboot-bootloader
copied below from other threads ---->
I find that a large amount of complaints in developer threads are due to people not properly wiping before a flash.
Of course there is times when a 'dirty' flash is fine, but if you're ever not sure, wipe as cleanly as possible.
fastboot allows for about the cleanest of wipes by the way. And each partition can be done separately too.
Code:
fastboot erase system
fastboot erase data
fastboot erase cache
can all be done individually, but to do these all in one command
Code:
fastboot erase system -w
If possible I recommend to do these steps before flashing a ROM, and now that you know you can do this all within fastboot mode i suggest to try it out, its quick and painless!
Don't forget to wipe your kernel too! (fastboot erase boot)
~Important~ If your device uses an emulated SD card (as in no removable micro SD but an SD partition on phone)
Then be careful wiping data/userdata as this will erase all contents of internal SD - you are forewarned!
ADB= Android Debugging Bridge (ADB)
[TOOL]Minimal ADB and Fastboot [2-9-18]
https://forum.xda-developers.com/showthread.php?t=2317790&page=12
First a short explanation:
Fastboot, like ADB, is a tool to communicate from PC to Android phone. There are times when it is a must to use, and times when it is just helpful.
ADB is used within your recovery or within your OS, but when you are in bootloader mode and need to communicate with your phone then you need fastboot.
And you may ask why would i ever need this?
Well many reasons. Main one is knowledge, learning the ins and outs of fastboot, like learning ADB, can get you out of many jams.
And if you want to unlock your bootloader this is done through fastboot. Granted HTC's unlock is... well crap, but for a Nexus this is how its done.
One other reason I have to stress is learning for safety reasons, This is about the safest way possible to flash firmware to your phone (ie Radio, Hboot, Recovery)
Lastly you may want to know the limitations,
There are many of course, this isnt JTAG, it will not resurrect a hard brick, but it often save peoples phones from 'soft bricks' and lots of time when know how and when to use it.
Think of fastboot as the program that takes over when ADB cant be used, it works with firmware more than software.

What Does Root Give Me?
1. Full control over your system
2. Ability to alter system files. You can replace many parts of the "Android Core" with this including:
o Themes
o Core apps (maps, calendar, clock etc)
o Recovery image
o Bootloader
o Toolbox (linux binary that lets you execute simple linux commands like "ls") can be replaced with Busybox (slightly better option)
o Boot images
o Add linux binaries
3. Run special apps that need more control over the system
o SuperUser (lets you approve or deny the use of root access to any program)
o Task Manager For Root (Lets you kill apps that you otherwise could not kill)
Tether apps (like the one found at [android-wifi-tether.googlecode.com])
4. Backup your system
o You can make a folder on your SDCARD and backup all of your .APK files to your SDCARD (helps if an author decides to "upgrade" you to a version that requires you to pay to use the version you just had)
5. Relocate your (browser/maps/market) cache to your /sdcard
6. Relocate your installed applications to your /sdcard
7. Reboot your phone from the terminal app easily (su <enter> reboot <enter>)
Turn the rotation lock off.
-------------------------------------------------------
SUMMARY - Regardless of version, rooting is the same... next
** Unlock the bootloader.
** Fastboot flash a Custom Recovery (TWRP).
** Download to the Tablet, Chainfire's SuperSU root updater .zip
** Boot into the previously fastboot flashed Custom Recovery, and flash the SuperSU updater .zip.
** Reboot - you're rooted.
-------------------------------------------------------
PS. I tried to maintain a log in Notepad during my upgrade. Unfortunately did not write detailed instructions and link to required files. Above is a summary of what worked for me.

Can not root

First my thanks to the forum key members for providing answers to queries and to all the key contributors of SW/ROMS in this forum. I followed the procedures from this forum to Flash / upgrade my Acer Iconia A500 on 4.0.3 ICS that was sitting in a trunk for the last few years. Summary of steps I tried out.
STEP 1: Install the Acer device drivers listed in the links in this forum on your Laptop/Computer even if by default your Windows 10 OS (assuming you are on Win10 like me) is able to recognize the A500 connected to the USB port.
USB_Acer_1.00.0524_A30HA31HA32H_A.ZIP
STEP 2: ROOTING the Acer A500.
1. The tablet should be already upgraded to stock ICS for A50x (or stock ICS A10x/A510 for other tablets).
2. On a tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch ON. If you do not see this menu, then click 7 times of the Android Build No. listed under settings and come back to the menu above to enable USB Debugging.
3. Connect the tablet to the computer (Before connection it is recommended to update the driver for a tablet from here: A10x, A50x, A510).
4. Since most of the discussions regarding flashing A500 were from 2011, the earlier Gingerbreak method for rooting did not work.
I downloaded the following file from this forum to root my tablet.
ICS_rooting_A10x_A5xx.zip
5. Open the directory with the unpacked archive. Execute file: for windows - runit-win.bat; for Linux - runit-linux.sh.
The root is received!
Note: The McAfee Antivirus software started tagging a file 'mempodroid' within this ZIP file Tools folder as a virus or malicious file. This rooting method uses the 'mempodroid' exploit which is detected as a VIRUS by McAfee and Qurantined. So restore from Qurantine and check list of files are still present in the folder. If not verify 8+8 files in folders again.
As per inputs in this forum, I restored the files quarantined and then suppressed McAfee SW for the duration of my upgrade activities on my laptop and was able to successfully extract all the files in the ZIP file to a local folder on the laptop. This ZIP file has adb and fastboot - two key programs useful for rooting your A500 apart from SU or superuser base file used in step 2. The file to run is the BAT file runit-win.bat if you are on windows. At the end of this step your tablet should be rooted. You may check by installing the RootCheck app from Google Playstore.

Hi sukasis, i was unable to root the tablet. I download all and run the runit.win.bat (trying normal, as admin, and open a cmd as admin and then navigate to the bat to execute).
- It say device connected
- Then push 7 files correctly
- Executing of the main script. (it freeze here a lot of time)
Then error: protocol fault (no status)
The file "su" isn't created
Not getting root!
I try in USB 3.0 and 2.0 same error.
I have windows 10.
I uncheck the Debugging mode and it's bring another error, so i believe the connection is good because in debug mode can push files.
I don't know whate else i can do.

Update Pixel Experience GSI ROM on Samsung S20 Series

Hello everyone !! I am currently using the Pixel Experience ROM as my daily driver and I came across the task of updating the ROM without losing any of my data. The ROM has an updater in the settings and allows you to install OTA updates, but for me that has not worked. Whenever I try to install OTA updates and I reboot my updated phone, it gets stuck on the boot logo. I came across a solution to this which is to manually flash the updated GSI ROM without wiping any of your data beforehand. I decided to make a YouTube tutorial on how to do that. If you have any questions please din't hesitate to ask !! I'll be happy to help !!
Pre-requisites
- Unlocked bootloader
- TWRP Recovery
YouTube Step by Step Tutorial
Downloads
Pixel Experience Latest Version: https://github.com/ponces/treble_build_pe/releases
Platform Tools for Windows and Mac: https://mega.nz/folder/LXBkjKha#2zqvR2EXg5gfupPe-xEZJQ
How to Update Pixel Experience GSI ROM on Samsung S20 Series
1. Turn off your phone
2. Connect your phone to your computer via USB cable
3. Press both power + volume up buttons at the same time until you see the TWRP logo
4. Once you boot into TWRP, click on "Reboot" and then click on "Fastboot"
5. Go to your computer and download the platform tools folders that I left above
6. Go to the website linked above and download the latest version of Pixel Experience
7. Extract both the platform tools file and the pixel experience file
8. Open a new command window or terminal window on your computer
9. Go to the extracted platform tools folder and choose the "Platform Tools (Name of your OS) folder
10.Look for the "fastboot" file and drag it into a new terminal window
11. Leave a space and type the word "devices"
12. Hit enter
13. If you see a bunch of random numbers followed by the word "fastboot" your computer has recognized your phone
14. Go back to the "Platform Tools (Name of your OS)" folder and once again, drag the "fastboot" file into the terminal
15. Leave a space and type the words "erase system"
16. Hit enter
17. When the process is finished you should see the words "finished" and "total time" in the terminal
18. One last time, drag the "fastboot" file to the terminal
19. Leave a space and type "flash system"
20. Go to the pixel experience folder you previously downloaded and extracted from the website
21. Drag the "PixelExperience.....img" file over to the terminal window
22. Hit enter and wait for the file to be flashed (this might take a while)
When flashing is finished you will again see the message "finished" and "total time" in the terminal
23. Go back to your phone
24. Click on "Reboot"
25. Click on "System"
26. Wait for your phone to restart
You should now have the latest version of Pixel Experience without losing any of your data !!
ENJOY !!!
