Hi everybody!
I am a branded SGS owner and due to my operator I am forced to use Android 2.2 (not even the 2.2.1 update is available) so I decided to flash the Voodoo ROM to stop the lag and as you may guess - I wasn't able to do it. My problems started with rooting the phone so I could give super permissions to ROM manager and use the CWM recovery to flash the phone. I was unable to do it by flashing it manually because of the "E:signature verification failed" error. Later, I managed to root the phone using the SuperOneClick application. Now, the problem is I cannot boot to CWM recovery - I always get the default Samsung recovery so I am unable to toggle the signature verification. I goggled intensively and if I'm not mistaken, there seems to be no existing solution to this combination of problems, so I'm asking for your help because I was very close to throwing a good phone out of my car's window all due to bad software!
I had smilar problem on my Folio 100.
1. Root SGS with SuperOneClick
2. Download Root Explorer.apk
3. Download recovery. img
4. Copy it to /data directory(if you find another data directory inside copy recovery there)
5. Connect SGS to ADB
6. Type "adb shell"
7. After that type "su"
8. Finally, type "cat /data/recovery.img >/dev/block/mmcblk0p7"
9.Now, go to recavery and install rom you want
DON'T WIPE DATE AND CACHE BEFORE INSTALLING

I bartered for a cheap chinese tablet this past weekend. It is an Ematic EGM003BL with Jellybean 4.2.2. I got it with the intention of trying to install the google play store and other related apps.
I have a tiny bit of experience with hacking android, mainly I managed to install Cyanogenmod on my wife's old Nook Color.
So at this point I have the tablet with a barebones install of 4.2.2.
I used SRSroot to root the tablet but it said that the tablet was already rooted. If I tried to click on the build number in the About tablet setttings, it told me that I'm already a developer.
I also installed Rom Manager, clockwork on the tablet (side loaded I think).
I downloaded the appropriate Gapps package from the goo link. I copied the gapps package to the device and that is where I'm at.
I really can't use Rom Manager to doanything because the tablet is an unsupported device.
I searched for info on installing the Google Play store and related apps on unsupported devices and the main results show how to install it on a rooted kindle fire.
The key that those instructions show is to put the tablet into recovery mode but I can't seem to do that.
When I turn on the tablet while holding the volume down button, I get a display on the screen shown in the attached picture.
use cmw or twrp to installing gapps from recovery

I have the clockwordmod rom manager program installed on the tablet but because its an unsupported device, it won't allow me to make a recovery. So I'm not sure where to go from there.
Were you able to find any solution for this. I have chinese tabled and want to install Google Apps on it. What is the process and/or way to do that.
Have a good root but no Gapps

After many hours of searching and trying different solutions I have actually got mine rooted and booted up with the procedure below:
thanks DVD2955
Forum thread: Is the Ematic Genesis tablet from Walmart rootable?
Update: The following is for your information I can not be held liable if you "Brick" your tablet as this worked for me, but try at your own risk!!
Read this page: Universal Root
Use this utility: Root_with_Restore
Then download the GAPPS from the above link and extract and find the folder "SYSTEM"
Open a dos command prompt window.
Now connect your tablet via USB and be sure that you have it set for USB DEBUGGING in the system / development
DO NOT TURN IN USB STORAGE.
Go to the folder where you extracted the download "Root_with_Restore" go to the folder 'STUFF' and from the command box type " adb device " you should see your tablet connected.
Run the "BAT" file from "Root_with_Restore" [I do not remember for sure but I know that "Other" did not work so I choose the option above it.]
Then find where you extracted the GAPPS system folder and type: adb push <if needed type in the full drive+folder listing>system /system : now wait.. you should see allot of screen messages. till you get a message saying complete.
Unplug the USB cable and turn off your tablet.
Turn on your tablet... this may take longer than in the past.. but you should have a working "GOOGLE PLAY STORE" once your system comes up.
It fails at the push for GAPPS
From my folder where ADB is located I run this command in the CMD window:
adb push C:\gapps\system /system
it returns this:
Push: c:\gapps\system/addon.d/70-gapps.sh -> /system/addon.d/70-gapps.sh
failed to copy 'c:\gapps\system/addon.d/70-gapps.sh -> /system/addon.d/70-gapps.sh' : Read only file system.
Need clarification whether mounting the sysem folder and setting permissions to rw will correct the failure. I am not the expert and have only rooted and modded Coby Kyros, Craig and Pandigital tablets.
Hello, I get just today a GoClever Tab r76.2 to reset the forgotten pin from the locksreen. Device was used mainly for Pou and Facebook, so there was no root, no usb debugging, my PC was not set as trusted device, just like from the store with PIN set. Installed system is Android 4.1
Because it took me whole morning and I found a lot of answers that "it cannot be done, you have to factory reset" I want to show you my steps to make this process easier for people in need. This method shouldn't erase any data from your device but always remember to have a backup
It is based on the following tutorial: http://forum.xda-developers.com/showthread.php?t=2601933 , but still it was not enough for me so I want to provide more details.
Step 1.
The very important thing is to install drivers for the device. To make this process the easiest I get my old, good Asus netbook with Windows XP installed. You can install it also on VirtualMachine, it is not very mandatory but my next steps will be based on this configuration.
There is a need for two types of drivers: Rockchip drivers to flash the memory and ADB Drivers.
1.1) Rockchip drivers can be found in the thread linked above, I am providing mirror at the bottom of this thread. Just doubleclick on the exe, accept the risk and install, that's all for now.
1.2 ADB drivers are provided in the second package attached. To install adb drivers go to recovery.
To switch tablet to the Recovery Mode you have to switch it off (not reboot), turn it on, just when the BootScreen will appear tap Vol+ until you will see opened Android Robot with exclamation mark. What's interesting, when you double click Vol+ this time you can switch to Android Recovery menu and factory reset the device
In device manager (Win+R, type: devmgmt.msc and press ENTER) install drivers for Tab r76 device manually, by providing direct location to the .ini file from the folder.
Leave tablet in Recovery.
Step 2.
People from some Russian Android forum prepared package with pre-configured adb for rockchip devices. Just download attachment 2.1, extract it, install, open Command Line and "cd" to directory with adb.exe, very useful.
Step 3.
Now we will root the device and install CWM. Download file from the attachment 3.1, unzip it and run "RK29Update.exe", don't click any button (especially the one called "Erase", it will brick your device), don't change any setting, your tablet will be not found at the moment. This package belongs to the author of the original tutorial.
Step 4.
In command line enter "adb devices" to check if your tablet is visible, you should see something like "0123456789ABCDEF recovery", if yes enter "adb reboot bootloader" and press enter. Tablet will reboot, the screen will remain black, system will install the Rockchip driver, RK29Update.exe will find the device (IF NOT just reboot to recovery again and reboot to bootloader from adb again, driver installation might interrupt this process), press Run button in the application it will flash the device with root patch and CWM, device will reboot to CWM recovery.
Step 5.
Download attachment nr 5.1 (original source: http://forum.xda-developers.com/showthread.php?t=2437946) and put the zip to the SD card (card has to be compatible with the device - most secure solution is having FAT32 filesystem), put it to the tablet, install zip from external source (not sdcard, it's internal memory).
After reboot of the device ("restart system now" option in main page of CWM) your device should welcome you without screen locked by any security possible and your settings should remain untouched.
From now everybody should be able to reset it's PIN in the easy way Have fun

Root & TWRP Lenovo Tab 2 A8-50F (MT8161)
Ok so this is a in depth tutorial on obtaining root and installing twrp for the device in the title. Anything in "quotes" eg, type in cmd "adb devices" quotes should be ignored. This guide is for those who know what root is and know there way around windows and Linux. If you did something wrong i am not liable and maybe you should have read things before trying.
EDIT: for those of you who want to root in one or two clicks i have added support for this device in the ZEUS TOOLKIT wich will root without installing custom recovery.. LINK >> http://forum.xda-developers.com/showthread.php?t=2644166
REQUIREMENTS/DOWNLOADS:
-Windows PC & Linux (Ubuntu. virtual box would be fine although i have my pc dual booting both os's)
-Driver Signing Disabled on Windows 7 and above
-Device Drivers
-SpFlash Tool (including scatter file)
-Adb Tools
-TWRP + SuperSU Files
-Insecure Boot.img
LINK FOR ALL REQUIRED FILES >> DOWNLOAD << DOWNLAOAD AND EXTRACT TO DESKTOP
Downlaod all of the above and extract/move everything to a folder which for this guide i will assume will be called ROOT on your DESKTOP
SOME READING:
The Lenovo Tab 2 A8-50F is a rather locked down device with the ability to reflash the stock rom on every reboot if required. In this guide you can only do things in a specific order to be able to get it rooted and stop the stock recovery reflashing. It took me a few times of (soft)bricking my device before i could get it sorted to a stable rooted system with twrp installed. TWRP recovery was not built from source by me personally (it was obtained from a russian website) although i have had to modify the TWRP image as it was boot looping but its sorted and working now. So roughly this is how things are going to go, we will use SpFlash tool to readback the system partition, then use linux to modify a file in the system.img the use SpFlashtool to refalsh the modified system.img. Then we are going to unlock the bootloader and then flash an insecure boot.img along with twrp and then root using chainfire's latest binarys.
THE GUIDE:
STEP 1 - installing the drivers
For this i will assume you you have already got adb driver installed if not please google it i personally used googles generic adb driver.
Please make sure you have disabled driver signing for windows "GO HERE". Now open device manager and right click on your pc's name at the top of the list and select add legacy hardware > click next > check "install the hardaware that i manually select from a list (advance)" and click next > highlight "show all devices" and click next > click "have Disk" > click "browse" > browse to the desktop\root\MTK Drivers all windows\ and choose the folder to match your windows installation and then choose the 32bit or 64bit driver file depending on your windows install > click open > click ok > highlight "MTK USB PORT" > click next > click next > if a warning pops up click install anyway > click finish. Your drivers are now installed for spflash tool to recognise your device.
STEP 2 - backing up system partition
Make sure your device is truned off and disconnected from your computer. Open SPFlash Tool form "Desktop\ROOT\SPFlash_tool\flash_tool.exe" > click "scatter-loading button > browse to "Desktop\Root\ and open MT6735_Android_scatter.txt > click the readback tab > click add > double click the entry which is now listed >browse to "Desktop\Root" and in the filename box type "system.img" > click save > check "HEX" > for region select EMMC_USER > for start address type "0xb000000" > for length type "0x74000000" > click ok > click readback. now with your device turned off connect the usb and the SPFlash tool will begin to backup your system partition to "Desktop\Root\system.img" wait until its finished and continue to the next step.
STEP 3 - editing the system.img
Now we have the system.img transfer it via usb (or whatever means) to your ubuntu machine place system.img in your ~/Home/ folder eg. ~/Home/System.img now open a terminal by pressing CTRL + T > type "mkdir output" press enter > now type "sudo mount -t ext4 -o loop system.img output/" press enter > type your sudo password > press enter > type " cd output" press enter > type "sudo mv recovery-from-boot.p recovery-from-boot.bak" press enter > type "cd" press enter > type "sudo umount output/" press enter. The system.img has now been modified and can be transfered back to windows. Goto next step.
STEP 4 - unlocking bootloader
With device booted to android and usb debugging enabled open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot bootloader". Your device will now reboot into fastboot mode when it displays "fastboot mode in the bottom left of the screen type into cmd "fastboot oem unlock" > press enter > screen will change and ask you to confirm do this by pressing vol+ > wait and when a screen with three boot options appears DO NOTHING and go to next step.
STEP 5 - flashing insecure boot.img
Now you should have the ability to flash the boot. Type into cmd "fastboot flash boot boot.img" the device will let you know it is done and when it is done flashing just type into cmd "fastboot reboot" and let the device fully boot and goto the next step.
STEP 6 - flashing modified system.img
now open SPFlash tool again it should have remembered the scatterfile if not reload the scatter file. In the main window of the download tab make sure ONLY system is checked then in the location colum click the space in line with system and browse to your modified system.img and click open. At this point before doing anything make sure your device is turned off and not connected to the computer in any way. Now click Download in SPFlash tool then connect your device via usb while turned off and the tool will begin flashing the system.img wait until it is finished and a green tick appears in flash tool and if your device does not boot automatically then unplug it and reboot it wait until it fully rebooted and goto next step. You can close flash tool for now.
STEP 7 - flashing TWRP recovery
with your devfice now booted with a custom boot and system image open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot bootloader" > press enter your device will boot into fastboot mode again when it has type "fastboot flash recovery recovery.img" > press enter > when its done type "fastboot reboot" > press enter now wait for the device to fully boot and goto next step
STEP 8 - flashing Supersu by Chainfire
Now your device has rebooted it will be missing the super user app and all binary's so open file explorer on your computer and copy the SuperSU-v2.46.zip from the ROOT folder on the desktop to the download folder on your device after doing that open cmd prompt and type "cd C:\Users\robert\Desktop\ROOT\adb" > (replace "robert" with your username) press enter > type "adb reboot recovery" > press enter. Your device will now reboot into TWRP recovery check the little box and swipe the arrow at the bottom to continue now touch install > touch Download > touch SuperSU-v2.46.zip and finally swipe to install. when it is finished reboot. Hey presto one rooted device with a fully working twrp. reboot and download busybox from play store and install as some programs like system app remover need some binarys from busybox.
After following the above steps you will have a fully rooted device wich can be backed up via twrp and flashed via twrp. now i have figured this out, i think its someone elses turn to build a rom for it preferably Cyanogenmod Thanks for reading this guide and all the best luck with your new rooted device. please remember to click thanks.
Have you found a way to root it without the need for Linux?
Hi
I would like to know if this guide will work for MT-8735
Thanks in advance,
Dimitris
Anyone found a way to root MT8735 version A8-50L or A8-50LC?
The files seem to be missing...
Any help would be much appreciated. I used the guide fine up until the Step 5.
Now I'm a bit stuck.

I used something called Kingroot along with the info and files found here https://forums.lenovo.com/t5/Androi...-to-root-TAB2-A8-50-WiFi-version/td-p/2181021 to help me root without using linux. There is a ROM listed there. If you use Kingroot.apk, you'll have to run it 2 or 3 times to get the ROOT to stick, then you can enable debugging, and oem unlocking in dev options. Afterwards, you can use fastboot to unlock the bootloader and once that's done, use the SP Flash tool to download Max Choen's rom to the device, install SuperSU and Busybox and your gravy!!!
what files? that post does not have any files provided and could someone upload the files that are missing from the post so we could also use them?

If you guys read the entire post in the link I sent you might be able to get where I got. I'm not a dev and not much for writing tutorials but my process went,
1. KingRoot
2. Unlock boot loader
3. Flash twrp via fastboot or flashify
4. Factory reset
5. Reinstall King root and re root.
6. Format and partition memory card
7. Install apps2sd
8. Install Xposed
9. Install obb to SD module
10. Enjoy tablet with 64gb of space with tons of large data games installed!!!! (Note that this step requires you own a 64 gig memory card)

I will post it in the morning, I think it's on my wife's laptop. The link I posted USED TO lead you to a post that had the files I mentioned and the process I followed. Now they are just suggesting you simply root using Kingo... Which is fine and dandy but does not give you the ability to format your memory card. I will post my recovery image for yall in the morning. You would just have to use KingRoot and then flash TWRP using Flashify once you have a successful root. Then you can format your card and install apps2sd of your choice and xposed with the obb2sd module! That's what I got going on, got TONS of large data games on the tablet cause I installed a very fast 64gb memory card, and BIGGITY BAM!!!! Turned this little budget tablet into something decent for the kiddos! Just wish we could do something about that terrible 1gb of memory, but hell, I was able to get this far so I'm pretty happy!:laugh::good:

Here it is!
Had some things to take care of first. Got a wife and kids to care for before I do my geek stuff. This is not a flashable zip! You must unzip the .img file and use Flashify after a successful KingRoot.
P.S. all credit goes to the original creators of this build of twrp I originally obtained in This Very XDA post we are conversing in! All I did was download this file, I am not a dev andi do not take credit or responsibility for any of the files I've used to root this device! Cheers!!!!
Okay... Thanks. I have SuperSU installed and working. TWRP installed and working, but I haven't unlocked the bootloader.
Will this prevent me from installing xposed framework, do you know?
And the which apps, by which developers, do you install to move apps to SD card?
Thanks for your help!

I am using Link2SD, Xposed OBB2SD module. That's about it. Not sure if bootloader unlocking is even necessary for anything.

Can you flash supersu from stock recovery or do i have to flash twrp first?
I used KingRoot (ver 4.8.2) to root my Lenovo Tab2 A8-50F Tablet.
I used KingRoot as part of a SuperTool. The SuperTool, using a batchfile script, also removed KingRoot after the tablet was rooted and then installed SuperSU.
The SuperTool (April 6, 2016 version) was created by xda's RootJunky for the Amazon Fire 7 5th gen tablet, using KingRoot and SuperSU, but it rooted my Lenovo Tab2 A8-50F Tablet, uninstalled KingRoot and installed SuperSU, all with only a couple of mouse clicks.
Even if you are already rooted with KingRoot, you can use this tool to uninstall KingRoot and install SuperSU. (Just run the tool, let it re-install KingRoot, don't run KingRoot but hit Enter on the SuperTool to then uninstall KingRoot and install SuperSU).
Lenovo Tab2 A8-50F Tablet info:
Model Number: Lenovo TAB 2 A8-50F
Android version: 5.1
Kernel version: 3.10.65
Build number: A8-50F_S000037_151023_ROW
Software version: A8-50F_151023
Hardware version; LenovoPad A8-50F
The SuperTool batch file script rooted the tablet with KingRoot and then uninstalled KingRoot and installed SuperSu.
I have since installed ES File Manager, Titanium Backup, Link2sd on the tablet. Root is totally working. Rooted with only a couple of clicks!
Just enable Developer options on Lenovo Tab2 A8-50F (by tapping tablet Build Number 7 to 10 times [Settings, About Tablet, Build Number (tap 7 to 10 times)]), enable USB debugging on Tablet in the Developer options settings.
Connect Tablet to Windows 10 with a USB data cable (I used the USB 2.0 port). When screen message on the Tablet mentions connections, make sure it is in the MTP mode.
Extract RootJunky's SuperTool Zip file to the Windows 10 desktop.
Run RootJunky's SuperTool (Amazon-Fire-5th-gen.bat) You may have to read the instructions on the pages below and install adb drivers. Pick option #6 Root. Choose Option #3: version 5.1.2. This will run a script that installs KingRoot, allows you to run it manually, and then removes KingRoot and installs SuperSU.
Press enter and KingRoot will be installed on the Tablet from the SuperTool. (approve any messages that appear on Tablet screen) Now don't touch the PC SuperTool until the Tablet is rooted.
Open KingRoot on the Tablet and run it. You may have to run KingRoot several times and the Tablet may reboot. Just keep running KingRoot until the Tablet is rooted. After KingRoot reaches 100%, then press ENTER on the PC.
The SuperTool will now uninstall KingRoot and install SuperSU on the Tablet.
Choose NORMAL SuperSU install on the Tablet when prompted. When SuperSU is installed, reboot the Tablet. Disconnect data cable.
After reboot the Lenovo Tab2 A8-50F Tablet is rooted. There will be a request by SuperSU to upgrade. Approve it. You can now install Titanium Backup, Link2sd, ES File Manager, etc. Your Tablet is rooted. As easy as that. THANKS ROOTJUNKY!!!

Hi,
The link does (no longer) work, can you please update it?
Thanks!
I tried when it was stock and it didn't work, then have put a couple different ROMs and it doesn't work. I does connect so I would think it's not a provision issue but something internally maybe? Currently I have Ephemeral Mate 9 rom. I checked the internet on the phone while the laptop is connected and it is working on the phone just fine. Is there something I can check with Root Explorer or SQLite Editor? I have a nexus 6 that works fine so maybe there is a value I can compare and see if something needs to be changed.
Did it wooooo hoooooo!!! Found an article and followed step by step and it worked great. I guess the custom rom doesn't have it baked in.
a. Setup ADB and fastboot drivers on your PC
b. Download TWRP recovery for your device
c. Download stable version of Systemless SuperSU [HERE]
Instruction
1. Flash TWRP recovery image
2. Flash Systemless SuperSU in TWRP recovery
3. While still in TWRP recovery, select Mount and check system. Make sure you allow changes.
4. Connect your phone to your PC and issue the below commands:
adb shell
echo "net.tethering.noprovisioning=true" >> /system/build.prop
adb reboot
5. Now, install Terminal Emulator app from the Play Store and launch it.
6. In Terminal Emulator, enter below code one by one:
su
settings put global tether_dun_required 0
exit
7. Now, open SuperSu, scroll to the bottom and tap on Full unroot. You do not need to patch you back to the stock recovery. If it hangs, just reboot and try doing it again.
You have now unlocked tethering and being an unrooted device, you can continue to use Android Pay. And, to get OTA update on your Nexus phone, do the following.
