[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.

I don't know about the camera, because I never use mine. Ill try to do some research on it.
If I remember correctly, it seems that spacemoose1 had a fix for the cd rom issue. Might wanna try posting in that thread. If you get an answer, bring it back over here and ill include it in the first post.

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.

I'm from Vietnam and I cant download the KhasMek rom via the host gunsforgeeks.com.
Could you guys please re-upload for me these rom [link belowed] on another hosts such as megaupload, duckload, mediafire ...

Just out of curiosity, why do you want to do it?
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!

I have no idea where to find the stock kernel. I need to do this because ever since I flashed CWM my auto rotate does not work.

After unlocking bootloader, the first boot takes a while, 30min more or less. Anyway, I suggest you to follow this guide which is kept updated: https://forum.xda-developers.com/yotaphone-one/help/guide-everything-to-yotaphone2-t3547194

Thanks a lot.:good:

Excellent manual!
I have small comment:
Step 2 - It's better change Original yotaphone flasher on YotaFlasherReworked.zip - it's from that theme.

*UPDATED**UNLOCK TOOL (4-2019) for ALL Versions of BLU R1-HD

BLU R1-HD bootloader unlock script tool, and TWRP install tool.
Download is a zip file, unpack it to somewhere you will remember. Run the dirty-cow-tool.bat // mtk-su-tool.bat
The included files and folders are set to hidden, in effort to keep them safe from accidental delete.
Must have adb+fastboot + drivers installed and setup prior to using tool
Easiest method to install adb + fastboot on windows is with "15 second adb + fastboot install TOOL"
LINK==>ADB+FASTBOOT
It is for windows
In linux :
"sudo apt-get install android-tools-adb"
"sudo apt-get install android-tools-fastboot" Some fastboot commands were missing when i used this one ie "fastboot flashing get_unlock_ability"
"sudo apt-get install fastboot" worked better when I tried. ( i used that command as a check before doing the unlock, so it was needed only for that check)
Using Tool
On Windows?
Unzip the downloaded file to a new folder, open new
folder and click on "dirty-cow-tool.bat". // "mtk-su-tool.bat"
Do the steps in order (1-2-3-4) to be unlocked, then
Step (5) to get to second page where step (1) is root
The rest is optional
On Linux?
Unzip downloaded file to new folder folder .
Open folder. Then open R1-Linux-tool-v2 folder
Open terminal from that folder and type
" . R1-HD-TOOL.sh "
Same order of steps (1,2,3,4) step (5) for extra
Steps (1 on second menu) for superSU root.
Second menu steps (2,3,4,5,6,7,8) are optional.
**Linux Note**
The tool uses "fastboot flashing get_unlock_ability" as one of the methods to check before doing the unlock.
The version of fastboot that installed with "apt-get install android-tools-fastboot" did not recognize
this command. But "apt-get install fastboot" updated some version and then the command was recognized.
******OTHER NOTES****
--- this has been mentioned in the general thread and the modified v17 thread, but It has come up again so I wanted to make note of it.----
--- The newest blu versions (V7.4.2 and V17) Have made changes to "toolbox" and this effects things like "adaway" and "titanium backup"
--- The suggested fix is to install busy-box. I have had success with the version from play store, some prefer to use f-droid version. Either one will do. Install it and open the app. From in the app you need to do an install.
CHANGE LOG
V1:. Initial release : removed
V2:. : fixed typos preventing proper function
V3:.: switch file verification to md5 check instead of "ls-l" comparison.
V4: current version: add extras page, add SU flash, de-bloat script, Added Fm Radio, Added pre-loader roll back
V5: Fixed wrong loop "goto" line that made preloader rollback do "MTK_BLU Debloat v2" instead
V6: Added manual pause to script for mods that need recovery (Extra's 5) . Added redundent recovery flash command .
Few reports of recovery "not Sticking" and needed to run the flash commands manually one by one. Maybe the redundent
flash will make it survive. If still having problem with recovery "staying install" try manually flashing
here is link to the steps needed. FLASH RECOVERY
V7 Improved logs Added line to make batch run as sub-process so if error occurs , will not close
V7.1 : Updated the fm radio install zip and include the needed selinux mode changer app
V8: fixed dependency of needing to be unzipped to location w/o spaces in name. (when used from location with spaces, tool used to fail to push needed files).
.. added more time to allow dirtycow to "spawn" its root shell. Recent testing has shown sometimes it takes longer than the 60 seconds allowed in the script. Now it is looped 3 times.
V9 Added full path to abd push lines for recovery flash files. included fastboot.exe file to address some version issue where user s version would not output text file I coded into script for a verification ( included file is called by script, no need to do anything different with it)
V10: Moved zip file to included folder to help preserve locations when unpacked, added device check before running tool; So tool not used on wrong device, Rearranged order of operations on extra's page. (recovery installed options) Push files while in android before rebooting to recovery( should improve reliability for multiple reports of not automatically installing options for some)
******I have received some reports that some devices are reporting "ro.build.product =R1_HD and not "BLU_R1_HD" like mine, so the added device check is blocking tool from starting If this happens to you , you can make edit to the .bat file like below.
Change this line
Code:
:next_check
find "BLU_R1_HD" "%~dp0workingproduct.txt"
To this
Code:
:next_check
find "R1_HD" "%~dp0workingproduct.txt"
it is line #23
V11: Updated device model verification lines
MTK-SU: Replaced all dirty-cow part with New MTK-SU binary(elf) from @diplomatic

Credits to @Diplomatic for his work on the Mtk_su that I used used to make this tool work again after Dirty-Cow was patched.

Items planed to be addressed in next release:
--Add few more file integrity checks to the extra's page
--Add copy log to clipboard option so it is easier to post log entry if needed-------*********----already-_added to github copy of batch file
--Add a verification step that checks what recovery is installed( to prevent trying to do steps on extra's page with stock recovery)
--Possibly move to a "fastboot boot recovery" instead of "adb reboot recovery" for the same reason as above
--Add wget or similar to the extra's items so initial "TOOL" size is smaller (not that 40-50MB is big, but to some it may be )
--Add additional "selinux mode changer apk" for fm radio install rather than just the note that says it needs to be found.

Works great on OEM 6.6, thanks for the tool!

So I got the one-click-root.sh done, maybe. Can some linux users go over it, make sure I didn't do anything stupid? I don't exactly have a device to check it with atm, and I am not pro with scripting, barely novice, so it is a pretty basic conversion of the batch file. Still, it might work . Just would like a few eyes on first.
https://github.com/theredbaron1834/Scripts/blob/master/one-click-root.sh
Also, I looked at dirty-cow-tool.bat. However, wow, more an advanced batch file, and I am not sure what the first half does, so not sure how to convert . However, it seems if anyone does get it, the eqiv of goto for linux is funtions. simple cheatsheet:
Code:
function stuff {
echo "this stuff is run via the function"
{
stuff #goes to stuff and runs function

thank you for your input.
As far as the begining of the batch, It is adding a few folders to the "path" variable so help ensure the "adb push" commands find the files it is trying to push. Then it sets some folder "flags" to hidden so that the files the batch needs don't get accidentally moved or changed. Then the large section with mostly "echo" that is to set up the "simulated" G.U.I.
The lines of just "::::::::::" are simply used to help with reading the batch file. i use them to seperate functions. They are not needed.
The lines with only 2 "::" are standard windows comment / remark line entries
The lines with 1 ":" are the beginning line of the loop/ function == the line that "goto *" searches for

Does Works to unlock 7.4.2?

Does Works to unlock 7.4.2?

It is supposed to. It is the same base codes used from original script, and that one was confirmed to work. I Do not have first hand use of V7.4.2 so it is only confirmed through other users.
The dirty-cow being used has been patched by google in Dec but blu has not rolled out the patch. So there is no reason for it not to work.

edit:
I have the linux version ready.
-the first step, (ADB Push) is ready. including md5 file checks
-step 2 is ready= running dirty-cow with md5 check before final writing to mmcblk device
-step 3 is ready unlocking bootloader = including check if unlock is done, but need to fix the "unlock_adility" check
I can make to file to compare and grep the line needed, but cannot "sed" the extra information or do a > < comparison
-step 4 is ready .--flash twrp
Finished 90% of tool.
still need to tweek the log feature.
I ran tests on the lop back to menu and test ran
1. push files for dirty-cow and md5 check . then made push fail to verify the check method was valid ==pass
2. run dirty cow commands and md5 verification on resulting file. ==pass
3.unlock bootloader --- I ran it (needed to fake the already unlocked check) it works == pass
4 . flash twrp --installed both version i have, both install fine ===pass
5 extra menus -- ran . install su-----debloat---rebloat--- add fm radio--- preloader roll back =====all pass
(bootloader roll back needs manual intervention to re-enter fastboot during the boot loop that is unavoidable)
6. instruction ====not written yet
7. exit yes it closes == pass
8. logs --- needs completeing

I just loaded this on my OTA updated 7.4.2 device. I would note that the batch file does not actually create the /sdcard/Download folder so you might need to go into the terminal and actually create this on your sdcard... also worth noting that this batch file **requires** an sd card in the device to do any of the loads in the "5" menu.

no it does not.
the /sdcard is the internal memory and the Download folder is already there.
you might be having issues but the folder is already part of normal system

Fair enough, my restore didn't have /sdcard/Download and I made an assumption that /sdcard was my mounted card. Thanks for the insight.

OOPS
found typo on V4 of tool. batch files sets variables for "return", from loop functions. And two returns were set to same label9, so if you had tried to do extra's menu option #8. "ROLL Back Preloader" , instead it was running option # 5. " MTK_BLU Debloat v2"
fixed and still reading and re-reading to search for errors.
This looks bad.
The reason I put together this tool was I felt it was important to make a way to minimize the problems usually associated with android modifications. By making "typo's" a thing of the past, and I found them in my own script.
re-posted V5 combined with linux V2--

Ok. After you have completed upto twrp install. You can do the options on #5. It is all programed and automatic. What is does is put zip files onto the phone and reboots phone into recovery, then recovery installs them.

I get up to the recovery installation, but then I can not access such recovery on the phone, If I turn it on with power+vol up, it takes me to the default factory recovery by blu.
And If I try to the super su step with the phone on, it resets it, and get it to the screen with the dead android, while the script just shows the ADB DETECTED message.
In case it's needed, my R1 HD is running on

You missed a step in the process.
As tool finishes the recovery install it comes to a "pause" in the script, you need to hold the volume up button on phone "before" pressing button on pc keyboard to continue.
If phone does a normal reboot at this point then the system will replace the newly installed recovery with the stock one.
Giving you the situation you have now.
This step I cannot control, you must press volume button on phone to get the boot menu, and directly boot into recovery to ensure that the install sticks.

This step I cannot control, you must press volume button on phone to get the boot menu, and directly boot into recovery to ensure that the install sticks.

When tool says Hold button , keep it held. Then continue the script. Phone should reboot to the boot menu. Then let go of volume
Some phones do not accept the fastboot reboot command, on those phones need to hold power to shut off. Then volume and power together to come on, release power when screen come on

[GUIDE] [MAGISK] Root stock Oreo B520 B521 B562

DISCLAIMER: I will not be responsible of any issues you could face following this how-to. You do it at your own risk!​
Here is a guide to root Honor 8 B521 Oreo. I did this on FRD-L09C432B521. Even if i think the "easy method" should work with other iteration of the phone (L02, L19, ...), I am not sure ramdisk is the same for all so test it if you feel lucky and please report if it works or not.
Requirements:
- Honor 8 running Oreo
- Unlocked Bootloader
- adb and fastboot installed on your computer (https://forum.xda-developers.com/android/software-hacking/alpha-adb-fastboot-installer-windows-t3637255 (Hit the thanks button)
Long method: (should work for all honor 8)​
1 -- Visit http://pro-teammt.ru/firmware-database/ and search your exact build (FRD-L09C432B521 for me). If you have several phones listed for your build, click the name of the build on the left. This will open an xml file on the first line of which you will see the exact model it is for.
2 -- Once you know which firmware is yours, click on "filelist". This will list the files for this build and theirs url. Copy the link pointing to "update.zip" (http://update.hicloud.com:8180/TDS/data/files/p3/s15/G3109/g1699/v159456/f1/full/update.zip for me). Decompress it wherever you want.
3 -- Download and run Huawei Update Extractor (Hit the thanks button) . Untick "verify header checksum" in "settings" tab.
4 -- In the "extract" tab, click on "..." and select "update.app" in the previously "update.zip" decompressed folder.
5 -- Files from "update.app" should now be listed. Find "ramdisk" and right click on it. Choose "extract" and you will be able to save the file wherever you want. Copy this file on your phone.
6 -- On your phone: Go to Magisk thread (Hit the thanks button) and download the latest magisk manager. Install it. Grant permission to the manager to access your storage in phone settings > applications.
7 -- Run Magisk Manager, it will ask you if you want to install the zip. Select "Yes". It will now ask if you want to flash the zip or to patch a boot image, choose this last one. Point to the ramdisk img you previously copied on your phone. Magisk manager will now patch it and create a new "patched_boot.img" file. Copy this on your computer.
8 -- On your computer: Open a command prompt where you copied "patched_boot.img". Enter the following commands:
adb reboot bootloader (your phone will reboot in bootloader mode)
fastboot flash ramdisk patched_boot.img
fastboot reboot
9 -- Your phone will now reboot and be rooted. To unroot, repeat the process (8) with your stock ramdisk (the one extracted with Huawei Update Extractor)
Easy method​
If your build is FRD-L09C432B521, FRD-L02C432B521, FRD-L04C567B520 or FRD-L09C432B562, you can use these already patched ramdisk.img.

On your computer: Open a command prompt where you downloaded "patched_RAMDISKL09B521.img" (or L02/L04 ramdisk) .
Enter the following commands:
adb reboot bootloader (your phone will reboot in bootloader mode)
fastboot flash ramdisk patched_RAMDISKLXXBXXX.img (the exact name depends of the ramdisk you downloaded)
fastboot reboot
Your phone will now reboot
Go to Magisk thread (Hit the thanks button) and download the latest magisk manager. Install it.
You now got root. To unroot, repeat the process with stock ramdisk.

You can indeed use twrp but as it is not completely functional yet, some people don't use it. Besides, Open Kirin suggest to flash their rom with fastboot so it limits the interest of having twrp.

Hallo! Is it possible to root my FRD-L09 Honor 8 Oreo this way too? And after then can I flash/install a Stock Version with Emui 5 Android 7 Nougat and then un-root again? I need my device unrooted, because of SkyGo App (Germany) doesnt work with rootet Devices ...
If theres another way to downgrade without these operations, please let me know and maybe show me the steps for that?! Thank you so much!

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.
https://forum.xda-developers.com/showthread.php?t=1622425
Flashing Bootloader Steps
-------------------------
1. generate your SBK from cpuid
2. put tab in APX by holding reset (small pinhole bottom right side)
and pushing power for 3-4 sec. - then release reset approx 1 sec. later
the screen should be blank and power button should be lit - plug in USB to PC.
2. Run A501 A.bat - when finished reboot tab to recovery (win 7 and under
right click on A501 A.bat and select Run as Administrator)
3. run Recovery(power and volume-) ->WIPE -> "Advanced wipe ->System (only)and swipe to wipe.
4. unplug USB and reboot tab to APX
5. plug in USB afer it is in APX mode -> Run A501 B.bat (win 7 and under
right click on A501 B.bat and select Run as Administrator)

Step 4: Download the files to install the bootloader
- http://www.mediafire.com/file/o7m2ouwo6zuod4d/A500-Bootloader-Nvflash.zip/file
Step 5: Follow the instructions in "how to.txt"
Step 6: Download a rom and flash in twrp
This tutorial is based of
https://forum.xda-developers.com/showthread.php?t=2450119 thread so big thanks to KaijiKun .
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
Uploaded: 2015-04-05 17:40:14
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.

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.
