[SPRINT] Sprint Tablet Owners Thread (Root, ROM, Flash to stock, CWM Recovery)

UPDATES STOPPED: MORE IN-DEPTH THREAD POSTED OVER IN DEVELOPMENT FORUM WITH UPDATED INFORMATION.
http://forum.xda-developers.com/showthread.php?t=1275031
There have been a number of threads regarding working with the Sprint tablet. Due to the lack of support for it, I've complied various items from all across the information tubes to help your get the full use of your Sprint tablet.
I've compiled the instructions from various sources across the internet. If I've failed to reference an item, let me know and I'll correct it.
Something to keep in mind - Heimdall and Odin use different drivers. You WILL NEED to swap between them each time you swap programs. It's unfortunate, but it's necessary.
Flash back to stock (EA24) with Odin
1) Download the files from here
2) Open Odin, and select PDA
3) Choose the appropriate .tar file.
4) Make sure repartition is UNCHECKED!
5) Press start.
6) When the process is finished, the Odin program will say Pass, then Reset.
Install Gingerbread on your Tab
1) Download this file
2) Rename it to update
3) Place it on the root of your SD Card (not in a folder)
4) Boot into recovery and choose "apply update.zip"
Install Rooted Gingerbread on your Tab
1) Download the rooted GB file.
2) Open Odin, and select PDA
3) Choose the appropriate .tar file.
4) Make sure repartition is UNCHECKED!
5) Press start.
6) When the process is finished, the Odin program will say Pass, then Reset.
Root your Sprint Galaxy Tab on FROYO
1) Download SuperOneClick
2) Enable USB Debugging
3) Connect your Tab to the PC
4) Run SuperOneClick
5) Select Root
6) You're rooted!
If you're on Gingerbread, see this thread
Heimdall (needed to flash kernel with CWM)
1) Download Heimdall and unzip
2) Download Microsoft C++ 2010 Redistributable Package
3) Put the Tab in download mode (Vol Down + Power)
4) Connect it to your PC
5) Navigate to your Heimdall folder and run zadig.exe
6) Choose Options>List all devices>Samsung USB Composite Device
7) You'll receive a prompt about the driver, accept to install.
Kernel with CWM Recovery for FROYO
1) Download the zip file here
2) Unzip the file. You will need the file named zimage only.
3) Open Heimdall Frontend
4) Select Browse under Kernel and navigate to the file you downloaded in step 1 and select it
5) Press Start
6) The Tab will reboot, but will freeze on the Samsung logo. Turn it off and boot into recovery (Vol Up + Power)
7) CWM Recovery will attempt to back your tab up, but will fail. Don't fret.
8) Do a factory reset in CWM Recovery and reboot
9) You'll freeze on the Samsung logo again Turn it off and boot into recovery.
10) CWM Recovery will back your Tab up successfully.
11) You now have a CWM backup. Reboot.
12) Your auto rotate is broken.
13) Download the rotation file
14) Put it in /system/lib/hw and change the permissions to match the other items.
Heimdall/CWM instructions compiled and cleaned up from here
Flashing ROMs
1) Keep in mind that the dev may suggest a specific kernel. See kernel instructions (step 1-5 above)
2) Put the ROM .zip file on the root of your SD Card
3) Choose install .zip from SD Card in CWM Recovery
4) Select the ROM .zip file
ROMs for the Sprint Galaxy Tab
1) Honeycomb - in early stages (Dev - spacemoose)
2) Better than Life - FROYO (Dev - oldmacnut)
3) Future Echoes - GB - (Dev - oldmacnut)
4) MIUI Port - (Dev - oldmacnut)
Finally, each of these steps involves the potential of rendering your device useless. Take care with each step. If you're not 100% comfortable with the process, post your questions. Hopefully, other Sprint owners will take note of the thread and use it.

I rooted a couple weeks ago and finally flashed cwm the other day, i wish this had been posted then! Nice job.

question, when i install cwm when i turn on usb mode it shows up as a cd rom on my pc, is that normal?

From what i've read, that is a known side effect, it happened to me too. Also my camera and screen auto rotation are broken. I know there's a solution to the screen rotation issue, but still looking for the solutions for the other two issues.

mounting the sd card
Yes I can confirm that spacemoose had a fix for the mounting of the sd card instead of showing up as a cdrom. I use it. I'll post it. Thanks spacemoose1!!!
Perform the following while tab is connected to pc via usb
1) open cmd prompt
2) cd to "adb.exe" directory (usually the android sdk tools directory)
3) adb shell
4) mount -t vfat /dev/block/mmcblk1p1 /mnt/sdcard
5) echo /dev/block/mmcblkp1 > /sys/devices/platform/s3c-usbgadget/gadget/lun1/file

Thanks, I gotta figure out how to do this.

Reflash the stock kernel.

Thanks so much for this topic. A lot of Sprint-centric instructions have been scattered around the forums and consolidating it in one place is enormously helpful.
Thanks!

[Q] Rooting help needed!

I am trying to root my new Nexus 4 and I am stumped. I am trying to follow efrant's instructions: http://forum.xda-developers.com/showthread.php?t=2010312
I successfully completed part D and now am trying to work through part E. I am stuck at step 3 of E: I downloaded SuperSU v 0.98 (is that really the one to get?) and I'm supposed to put that in /sdcard. Where is /sdcard? There is no SD Card in a Nexus 4. Is this a hidden folder somewhere? Do I have to make it? How can I see that folder? I am using a Mac and the Android File Transfer program window shows no sdcard folder anywhere.
Also: Why does another unlock guide talk (http://forum.xda-developers.com/showthread.php?t=2018179) about pressing "Build Number" seven times? Why doesn't efrant's guide mention this?
I don't follow this part at all. How do I put that damn file where it needs to be?

Just download the N4 toolkit. Will do everything you want.

When you plug the phone into the computer /sdcard is the folder that comes up. Just place it in there.

Do it the proper way and download ADB drivers
http://forum.xda-developers.com/showthread.php?t=1514942 (enable USB debugging)
set up ADB environment
adb reboot bootloader
fastboot oem unlock
unlock bootloader on phone
download clockwork recovery or TWRP (i suggest TWRP)
put the .img file of recovery into your /platform-tools/
fastboot flash recovery <name-of-file>.img
then boot into recovery and there you can flash your ROM, gapps, kernel.
In the long run, IT WILL PAY OFF because eventually YOU will be faced with a problem with your phone and you won't be able to recover your phone because you dont know basic fastboot or adb commands all simply because you wanted to use a toolkit. People are already asking on how to use adb / fastboot in Q&A, we can reduce the clutter by not having people use toolkits and actually learning how adb / fastboot works when it isn't a very complicated thing to do at all

As stated in my original post, I am using a Mac. Not a PC. Therefore I don't use ADB, nor any other drivers. I also do not see, as stated before, any sdcard folder. I don't, I repeat, don't see it.

Can't write on internal SD card after root

After having rooted (with nexus 10 toolkit v1.3.0) my nexus 10 and flashed AOPK Nexus 10 (WIP) Task650 & Ktoonsez (1-4) rom, I'm unable to upload to, change or move any files or folders on my internal SD card. I installed Root Explorer and changed from Mount R/O to Mounted as r/w. Access is granted by Super SU. I also tried to change permission settings, unfortunatedly without any success. There appeared the following message:
"Warning
Permissions change was not successful. Please note that some file systems (e.g. SD card) do not allow permission changes."
Is there a possibility to change these permissions in order to be able to create and move files and folders on my SD card?
Thanks for taking your time to help me with my issue!
Anzirothu

1. Clear cache
2. Clear dalvik
3. Fix Permissions
forgot something ?

Thank you for your reply, Patrik!
1. done.
2. done.
3. Fix Permissions - How? With cwm? I did fix permissions with cwm recovery, but the problem persists...

Just so we are clear, when you say "upload to, change, or move" are you meaning you cannot copy a file from your computer to your Nexus 10? Or just that you cant arrange stuff through root explorer from within the tablet itself?

Neither copying from PC to Nexus nor arranging stuff through root exlorer from within the tablet itself. I can't even download an email attachment and put it to the SD card. The card seems to be locked.

I had that problem once but I dont remember what caused it or what exactly I did to fix. I think I just did a complete wipe by locking and unlocking the bootloader and then installing a new ROM again.

I think I did this too (unroot, lock bootloader, then root and unlock bootloader) and then installed the same rom again. I will try it this time with another rom.
Isn't there really no other solution to get access to my SD card again??
Thx for your help!

Are you using a toolkit to unlock and root? If so them maybe it is not doing something right and it messing up a permissions somewhere. It could also be a driver problem on your PC with being unable to copy a file to the tablet.

Thank you for your help!
I am using the nexus 10 toolkit V1.3.0. Right now I'm trying to intall twrp recovery with a fully wiped sd card. No easy task fot me being a noob...

In ClockWorkMod, make sure that /data is mounted
Then download the Android SDK: http://developer.android.com/sdk/index.html
I usually put all the files just in C:/android-sdk-windows
Once you have it all there open up the SDK Manager and download all the additional files needed. You probably only need to download "Android SDK Tools" and "Android SDK Platform-tools", but I always download the other files for whatever version of Android I am running, in our case Android 4.2. That way I have them if I need to do something else.
Once downloaded, open the Android-sdk-windows/platform-tools directory. copy:
adb.exe
adbWinApi.dll
adbWinUsbApi.dll
fastboot.exe
to your base C:/Android-SDK-Windows directory.
Now open command prompt from Start -> run
type: cd C:/Android-SDK-Windows
type: "adb devices" and it should list your tablet. It will actually say something with your devices serial number and then "Recovery" after it, showing your tablet is in recovery. If you dont see this then you either dont have your tablet mounted right from in the Recovery, ClockWorkMod is stupid, or you dont have working adb drivers.
Now copy the ROM you want to flash to C:/Android-SDK-Windows
Then type: "adb push blahblahblah.zip /data/media/0"
That should push the ROM to the root of your SD card. Give it time, it takes a while to push a ROM file. Once it is done, flash the ROM.
That *should* put it in the right spot where it looks like it is on your "internal storage" (what you see when navigating files within the ROM). If you dont see the ROM in clockworkMod then keep navigating back to the root of your internal storage and then open up "data", then "media", then "0" and you should see it. If you still cant find the ROM, push it again but just use "/data/media" as the location.
I just did all these steps myself to verify I remembered it all correct and I was able to successfully copy a ROM and find it on my tablet to flash by doing everything I just listed above. SO you should be good to go if you follow all those steps properly. I know it looks like a lot of work, but it really isnt and will go quite fast. Most of it is just the setup for getting ADB and Fastboot ready to use.
For a ROM to install, I would recommend to someone new like you either of these:
http://forum.xda-developers.com/showthread.php?t=2071082
^^^^^ That one is pretty close to the stock ROM with a few fixes and a couple extra features
or: http://forum.xda-developers.com/showthread.php?t=2071082
^^^^^ This one is pretty much CyanogenMod 10.1, but built by a different guy and not pulling every new thing from CM, just the "cherry picks" of features. It tends to be a bit more stable and less buggy than the real CM10.1 nightly's
And for a kernel you can flash and forget you will want to try this one:
http://forum.xda-developers.com/showthread.php?t=2098157
^^^^^ To flash that you will want to do a similar thing as how you pushed the ROM to your device. Only this time you will copy the kernels' "boot-r4.img" file into your android-adk-windows directory and use the command: "fastboot flash boot boot-r4.img"
While I enjoy the KTManta kernel more, it does require a bit of tweaking to get running perfect. Which is one of the things I like about it because of all the options to tweak. But for someone just learning this stuff that would be a bad thing, so Franco's kernel is much better than stock and doesnt require you to adjust anything once it is flashed to your tablet.

Unroot Att I337UCUAMF3

I used the following to root my device now I would like to unroot please help.
UPDATE: This root method also has been verified to work with AT&T Galaxy S4 on MF3!
It involves an external microSD card that must be formatted in exFat format (you can do this easily on Windows by right-clicking and selecting format, you should be able to choose exFat as for format type), download and unzip the script, then copy all the files to your microSD card.
Download root script for VRUAME7 (Verizon)
Download root script for MF3 (AT&T)
Next, go ahead and download Terminal Emulator app from Play Store, open and type:
cd /mnt/extSdCard
./pwn
./script.sh
Once that’s done, simply download/install SuperSU from the Play Store, let it replace the Superuser app and also update the binaries. Reboot and you should have root!

SuperSU has a full unroot option, just male sure you remove busybox and check in your /syst/bin folder for any extra files. There's a thread somewhere you can search for.

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

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.
https://forum.xda-developers.com/showthread.php?t=1622425
Flashing Bootloader Steps

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.
