Dear All,
So here goes the first unofficial ROM (thanks to Ukrainen) for Penta IS709C. Its a Jellybean 4.2.2. and even though is still in very early phase of testing, sharing it for others to try. I am not a developer but if you find any issues, please let me know and I'll forward them to the developer...
Use it at your own risk. All your existing data will be lost and I am not responsible if you brick your device (however will try and help you bring it back to the state you purchased it in, but no guarantees)
This is what you need to do:
1) Download the zip file from here: https://docs.google.com/file/d/0B5T-ylTRyyKdczY3Y1A1VTZXUms/edit?usp=sharing
2) Extract it to your desktop or any other loaction on your PC/ Desktop you prefer
3) In the folder 'CustomRom4.2.2forPentaIS709C', right click on RKtool.exe and click run as administrator (on Windows 7, figure out your self for any other OS)
4) Put your tab in flash mode [switch it off, press and hold the menu button (middle button of the 3 buttons below the camera) and then insert the usb cable already connected to your PC]
5) Your PC will install its drivers automatically, it auto driver installation fails...go to device manager on your PC and you'll find your device in other devices. Right click on it, click on update driver software, click browse my computer...and then point to the drivers section of folder 'CustomRom4.2.2forPentaIS709C'.
6) After driver update Click on EraseIDB of RKtool.exe window and wait for it to complete
7) Click on Run (You need not do anything after this step, just sit and enjoy)
8) Your tab will reboot once the above step is completed and the recovery system will do some formatting.
9) It will reboot once again and within next 5-10 min you'll have a working Android 4.2.2. on your PentaIS709C.
If you want CWM Recovery (thanks to Fun_), after completion of above steps (i.e. update to 4.2.2) download the zip file from here: https://docs.google.com/file/d/0B5T-ylTRyyKdcUlBMVFab3ZIY1U/edit?usp=sharing, unzip it, put yoour tab in flash mode, open RKtool.exe, uncheck all the boxes except for recovery, point the path for recovery to the recovery.img of unzipped CWM folder and click run. Your tab will reboot after completion, do a manual reboot if tab is hanged at boot logo for more than 5 minutes and you'll have the CWM recovery on your device.
Enjoy....
Known issues:
1) Camera is not working....
2) With the tab in portrait mode, if we touch and hold any icon, the screen gets inverted...
I deserve a thanks if I've helped you ever.... Please click thanks if you agree...
All the best

I need some serious help... I think I bricked my Nextbook Premium 7. I compiled a custom ROM and forgot to included a launcher. Didn't realize it until after I flashed it. My tablet is stuck in a bootloop and only way to shut it down is with the reset [pin hole] button. Power button does nothing except start it up. I have already tried to put the stock update.img on an external SD hoping it would boot from there, but it did not. I am not sure what to do next, I have looked all over google and xda. Please help!
Thank you in advance!
Do you have a custom recovery installed? Did you try installing it threw fastboot files and cmd prompt on computer?
Please hit the thank you button if i helped!

There ins't a custom recovery installed, this device flashes by detecting an update.img and askes to install it. It doesn't get past what would be considered the kernel screen. This tablet doesn't work like a standard android phone. There are no hard buttons except the power button, so attempting to get into any recovery is not possible. It also doen't boot enough to add any files to it.
Sounds like your screwed. Sorry.....

Ok, just bricked my Nextbook 7
Here is how I flashed a firmware without access to recovery:
If you are in a bootloop, Connect USB and Power.
Press and hold pin on back until you hear windows try to detect a device but the screen is off.
Download this: http://arctablet.com/assets/tools/Fi..._Tool_v1.4.zip
Install the driver from the drivers folder.
3. Installing the drivers on the computer
Following the tablet entering in recovery mode, the computer should now show it has found a new USB device and prompt for a device driver. Select the appropriate driver in the driver directory from the Rockchip Flash Tool 1.4 package.
It will then install the driver for RK29 Device
4. Sending the firmware to the tablet
The flashing tool should display a green square around the number 1 in the lower left area of the Windows application.
Select the firmware file to flash using the button in the top right area of the application. Select the update.img file from here:
http://www.multiupload.com/NQHSNZJSO2
Then push the Upgrade button to transfer the selected firmware to the tablet.
The firmware will be copied to the tablet, a progression counter will go from 0% to 100% on this step, followed by a verification.
You are done, let the tablet reboot and update itself. It should take a few minutes for the flash process to finish.
This procedure has been successfully tested on Windows XP 32 bits for flashing a bricked NextBook 7 Premium YF1011 (but should work on others)
Help !!
Please help, got the tablet yesterday NEXT7P12 YF091211085 by flashing the official site was a brick, the tablet will not turn on, the computer does not see it.
screen moved after installing rom
Hi, i don't know if I'm on the right place but if anyone can help me, please I haw the Nextbook 7 premium and have instaled costum rom on it, but after rebooting my screen position has moved from right to left 2 cm and from up to down 1 cm , so my screen is moved I don't know why I have try to install 3 other rom and factory firmware but the screen is still moved or should I say cut. Any ideas? please I have try to google it but no luck...
I no longer have my np7 but I did try just about every ROM for it. Never have I had or seen an issue like this, and in truth I can't think of what the issue may be.
There are different np7 variants and some don't play nice with custom ROMs (built sept 2012 and older lose WiFi) so you might have a model that can only use one software due to hardware/firmware change.
There never was much development for the np7 here, I think finlessbob and others are still working on it at freaktab.com maybe see if they can help

I've heard this works for other people. With my phone it doesn't. When I plug it in, it doesn't show an unknown device. I've already downloaded and installed MT65xx Preloader and tried out a VCom, but still nothing. I've been going at it for a week, so if anyone's got an answer, advice would be great. Thanks!

Hello to you all!Warning:
Code:
[COLOR="Red"][SIZE="4"]Your warranty is now void. I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed.
Please do some research if you have any concerns about all contained in this tutorial
before you follow it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.
But since i'm a nice dude i will try to guide you anyway:)[/SIZE][/COLOR]
In this tutorial we will learn how to:
- achieve root on our L7 II (Both single and dual-sim, so P715/P710 and all the derivated phones from them) by LG running a Custom Rom or Stock KK Rom.
FOR THIS FOLLOW ALL STEPS.
- unbrick/flash to a specific firmware using Lg Flash Tool (In this tutorial there are only 2 KDZ files stock JB for P710 and P715. If you want to recover from a brick or want a different KDZ file you can find them over here: http://lg-phone-firmware.com/)
FOR THIS FOLLOW STEP 1 AND STEP 2 (install all drivers including adb and download the files that are needed at Step 2).
- flash with CWM (There are 3 methods I describe. Use the one that suits you the best. You can flash any *.zip that is suitable for your device.)
FOR THIS FOLLOW STEP 5.
Save your data you need, you will lose all data so backup with Titanium Backup or a program you like the info you need.
ALL DOWNLOADS ARE AT THE BOTTOM OF THE POST!
This tutorial will be split in steps as the following:
1. Preparing the Windows machine with the right drivers and software.
2. Reverting back to Jellybean Stock Rom.
3. Rooting on Stock Rom (Jellybean).
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
5. Flashing KitKat or a Custom Rom through CWM.
6. Flashing Root through CWM.
So let's start the job.
1. Preparing the Windows machine with the right drivers and software.
Uninstall everything related to LG from Control Panel (Drivers, PC Sync etc).
Restart your PC.
Download and unrar the archive "LG Drivers.rar".
Install both files inside and restart your computer.
Download "adb-setup-1.4.2.exe" and install it (answers should be y y y and install the drivers when prompted).
Download "Framaroot-1.9.1.apk".
Download "LG Flash Tool 2014.rar".
Download "Free LG P710.rar"
Download "P710 Stock KK.zip". -> Stock KK image with Stock KK kernel in it made from the original V20 KDZ (Open Europe).
Download SuperSU
*Download "P715 Stock KK.zip" and "LG P715 (JellyBean).kdz" if you are running a dual-sim version of the phone.
*Download all the files you need!
From now on I will consider you have this files and I will just call their names when to use them.
2. Reverting back to Jellybean Stock Rom.
Open the back cover of your phone and pull the battery out. Wait about 10 seconds. Put the battery back in.
While HOLDING (keep pressed) the VOLUME DOWN BUTTON insert the USB Cable in the phone (you need to have your USB cable inserted in an USB 2 port from the back of your PC).
When you see the yellow screen with emergency mode stop pressing the button.
Unplug the USB from the phone and then plug it in again.
Unrar "LG Flash Tool 2014.rar" and open "LGFlashTool2014.exe" with right-click Run As Admin.
*If you cannot open this program you need to install "VC_RedistInstaller.exe". You are missing some libraries of visual C++*
*IF YOU HAVE ANOTHER PHONE (another LG or P715) DO THE SAME INSTRUCTION AND REPLACE JUST THE KDZ FILE ON "Select KDZ File" TO THE ONE YOU DOWNLOADED AND IS SUITABLE FOR YOUR OWN DEVICE.
Move PhoneMode from DIAG to EMERGENCY. Select KDZ File: you have a file called "V10J_00.kdz" in the same folder as the tool. Select that. Press CSE Flash (CAUTION!!! This will reflash the phone and YOU WILL LOSE ALL YOUR DATA SO BE WARNED).
Another screen will open and press START.
Another screen will open once again press OK.
At a point you will get an error like "Offline BLA BLA". DON'T DO ANYTHING DO NOT PRESS OK.
Wait until your phone reboots and then you can close this tool.
Remove USB cable.
IMPORTANT STEP:
Pull out the battery. Wait 10 seconds put it back. While holding VOLUME DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo and stop pressing POWER. Keep pressing the other 2 until you see android robot doing things. Wait until the phone boots.
CONGRATZ you are on JELLYBEAN (Or the KDZ you chose).
3. Rooting on Stock Rom (Jellybean).
When you see the welcome screen just fast forward everything.
Go to system settings->security->tick Unknown sources->OK.
Go to system settings->developer options->OK->tick USB debugging->YES.
With an SD card reader or with your USB connected as Media Sync (MTP) copy the "Framaroot-1.9.1.apk" to your SD Card.
Using the phone's FILE MANAGER go to external_SD and click the Framaroot you just copied. Run it using Package Installer Just Once and Install.
When finished press OPEN. At the first choice choose Install SuperSU and then press on "Gandalf". You will get Success. Press OK and reboot.
You will see SuperSU in you apps.
YAY! IT'S DONE.
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
*SAME FILE YOU NEED FOR LG P715
Earlier you have download "Free LG P710.rar" and in the first step you installed ADB. We will use that now.
Unrar the "Free LG P710.rar" and place the 2 files ON THE ROOT (only on root) of the SD card using device mounted in MTP mode or SD card reader. Put back the card if you use the second option.
WARNING!!!
This can mess up you device so just do what i say step by step!
Plug the USB Cable in the Phone once again and use MTP connection mode.
Click Start+R type CMD and press ENTER.
Run the Following with copy paste to CMD.
Code:
adb devices
You will see your device.
*IF YOU CANNOT MAKE YOUR DEVICE BE RECOGNIZED IN "adb devices" do this:
Install this: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=ro
Open terminal and continue with the steps down below.
Code:
adb shell
You will see something ending with $.
Code:
su
Unlock the dvice if it is locked and your phone will ask for superuser permission press GRANT.
Code:
dd if=/storage/external_SD/APPSSBL.bin of=/dev/block/mmcblk0p5
This will copy the unlocked bootloader to the bootloader partition.
Code:
dd if=/storage/external_SD/recovery.img of=/dev/block/mmcblk0p17
This will copy the CWM to recovery partition.
Code:
reboot recovery
This will reboot your phone in CWM if you followed all steps correctly.
GREAT SUCCES we have an unlocked bootloader and CWM.
Close your CMD.
Unplug USB.
5. Flashing KitKat or a Custom Rom through CWM.
*IF YOU WANT TO FLASH ANOTHER ZIP FILE OR YOU ARE ON P715 JUST USE THE ARCHIVE YOU NEED AS REFERENCE, NOT "P710 Stock KK.zip". CHOOSE THE FILE THAT IS MOST SUITABLE OR YOU THINK IT'S BEST FOR YOU
I made "P710 Stock KK.zip" you downloaded. This is the stock image for KK Open Europe. Here you can either flash mine or search for a Custom Rom for your device. Either way you will follow the exact same steps but with a different archive. I will take for reference the "P710 Stock KK.zip".
Plug USB in.
You Navigate using Volume Up Button (UP) and Volume Down Button (DOWN). The Power Button is OK.
Do this:
- Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
- Go to "mounts and storage" and do the following: "format /cache" and "format /system" everytime with YES as second option. Press "go back" once.
- Go to "advance" and then "wipe dalvik cache" and YES. Press "go back".
Here you have 3 options.
OPTION 1.
Use an SD card reader copy the Zip file to the root of the SD card or copying using CWM. Using CWM you navigate with Volume Up and Volume Down to "mounts and storage" press POWER BUTTON (OK). Go to "mount USB storage" and your SD card will appear in windows and you can copy. After that you press "go back" 2 times to get to the main menu.
Go to "Install zip" and then "choose zip from sdcard". Search for the zip file and press OK then go to "YES" and press OK. Wait until done.
Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
OPTION 2.
Copy the file using adb push. Open a CMD window in Windows (Start+R type CMD press ENTER). Copy this:
Code:
adb push
With the space. After space go where you downloaded the zip file highlight it and drag it in the CMD. Leave a space after that and type /sdcard (without space after).
Wait until done and close CMD.
After you copied the file to your sdcard go to "install zip" -> "choose zip from sdcard" -> search for the "P710 Stock KK.zip" press OK then go to "YES" and your installation will beging. Wait until it is done. Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
NOTE: In the zip i made i don't know why i couldn't sideload it but usually you do not have to copy to SD card to flash something. You can sideload it. All you have to do is:
-Go to "install zip" -> "install from sideload"
On your computer open a CMD and copy this :
Code:
adb sideload
Copy with space and after what you copied grab the zip you want to flash and drag it to CMD. Hit ENTER. Sideload will send the zip to phone and process of flashing will start. After it is done reset to factory again.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
CONGRATZ YOU ARE NOW ON KITKAT. I HONESTLY THINK THAT YOU SHOULD GO FOR THIS CUSTOM ROM OVER HERE BECAUSE IT IS LIKE 10 TIMES BETTER THAN THE STOCK KK. TO INSTALL JUST DOWNLOAD THE ZIP FILE FROM THERE (V2) AND FOLLOW THE TUTORIAL WITH JUST REPLACING THE ZIP WITH THE OTHER ZIP.

6. Flashing Root through CWM.
On some ROMS root will not be there. To avoid this we will flash the SuperSU zip.
To get to recovery you have 2 ways:
- From you ROM connect USB as MTP or in a way that ADB recognizes it (device gets detected by adb devices) type adb reboot recovery.
- Close your phone. At the same time press VOLUME DOWN + HOME BUTTON + POWER BUTTON. When you see the LG logo stop pressing POWER BUTTON. Keep the others 2 until you are in CWM.
Install the SuperSU zip with one of the ways you learnt at step 5.
You are rooted now.
Hope everything worked out fine for you and you are happy. Have a really nice day.

Does P713 have NFC?
This method actually works for dual sim too,you just have to use P715 kdz's.

Yeah it does. Maybe this weekend I will mod it. It is usefull for recoverying from soft bricks also just Step 1 and 2.
it was great till i get stuck on boot loop ,,, now how to solve ?
thanks for the useful guide.
I have a problem though, I cannot go after kdz extraction.
LG Tools stops with an cryptic error like [009.400.120.120.120]PC????? and looking at the log it seems there are troubles in unpacking the kdz file.
I have tried with different roms but still the same.
Does anyone has the same problem ?

I can't really understand you. The point of this guide is to get root on kitkat so flashing with lg flashtool will not work if you want kit kat rooted. I tested that V10J on my own l7 2 (p710). Also if you flashed Jellybean did you press CSE Flash not Normal Flash?

Ok do that step again. Flash with that tool using the image i provided. After the last ok. Even when you get the offline error don't touch it until phone reboots. If you get bootloop do this.
1. Pull out battery. Wait 10 seconds. Push battery back in.
2. While holding POWER DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo then stop presing POWER. You will get to see android guy doing stuff. Then tell me if it's ok.

Don't forget to press the thx button it's in the right . I will add this to the tutorial I didn't need it but who knows.
I managed to do the "root" step, but somehow cannot proceed with the next step.
When I check "USB debugging", the phone doesn't connect to the computer for some reason. I tried multiple computers, with no luck. The "adb devices" says just empty "List of devices attached".
If I disable the USB debugging, the phone gets connected just fine, if I enable it again, it gets stuck on "Connected as installer", and doesn't connect as MTP....
Any idea how to fix this?
Do you have drivers installed? Also when you press MTP cancel if your phone wants to install anything.

I tried everything, without luck. I ended just using terminal emulator to copy the files on phone directly (might be cool to add this to your tutorial, as someone else can also have this problem). So, now I'm on Amigas ROM - makes a HUGE difference! Thanks, looking forward for some other custom ROMs for this phone..

Strange huuummm. I don't know. Yeah i will add Terminal Emulator also in weekend. Never happened to any of my phones before... Maybe driver conflict on your PC or something like that.

Good morning,
I think i just need a ROM or a Backup.
I installed the systel recivert TWRP with flash tool, it works but missing the OS.
With flash tool:
I used those files: logo.bin, lk.bin, MBR, preloader.bin, secro.img, MT6582_Android_scatter.txt, boot.img, recovery.img, system.img
But i didn't have any files for: ebr1, ebr2, cache, usrdata
A the TWRP seems to work, i think i can simply flash a zip file on the SD-card.
Thank you four your interest !
ps: I was invited to type the captcha and it was very very very very difficult to read (i tried more than 20x).

*removed link because not passed limit yet*
Hey shanti, I too have been stupid and managed to remove my system. I was trying to navigate TWRP (so much more used to CWM with previous devices) and accidentally erased the system instead of backing it up. Is it possible to flash this with fastboot? I did managed to back up the boot files, just not the system, and I don't have a external SD card (I might be able to swap the one off my mums phone though at some point).
Thanks
Will
PS. If it helps, I use Arch Linux (32 bit) because my laptop chargers broken I'm using my spare PC, and also the phone is the Medion variant (LIFE P4502 from Aldi)
EDIT: Buying SD Card today
Can somebody help me to make cm11 port? Thanks
Were can i find chinese supersu? I instaled from google but really have problemy with SD, lost settings after reboot, and other problems

Hello,
Is this Original firmware, and how to do it?
Thanks for helping me.
Still need original ROM for Medion P4502
Can someone tell me where and how to recover my phone?
It doesn't connect to my network provider (I tested 3 differents Sim cards), and he also change his MAC address at WIFI connection.
I need original ROM and how to put it back (how to do).
Please help me as I don't want to send it back to Medion service (3th time), as they didn't do anything.
A friend has the same phone.
Is it possible to make a copy of his ROM (and how) to put it back on mine?
Thanks for helping me.
No answer, so phone send back to Medion repair service.
Hope this time it will return in good conditions ...
Please help!

Hi Dromadore,
Did you end up to fix you bootloop issue? Can you please share your findings with me as I am desperately looking for a solution?
Cheers,
Hi all!!
This is for all the people who managed to softbrick (or hardbrick) their Lenovo Tab 3 8' (TB3-850F) tablets!
All you will need link, at the end of the post. I don't know for how long it will be up, but you can use it for now.
By the way.... Should you find something useful here... please hit the thanks button in the end
A. Unbrick
This requires flashing a clean stock rom. You will need:
a. stock rom for the TB3-850F (Google is you friend )
b. Sp Flashtool (you can download from their official site). From there, also download the MediaTek USB VCOM drivers and Driver Auto Installer v1.1236.00 (or any latest version).
Steps:
1. Install the windows drivers you downloaded
Note : If you encounter problems installing Windows drivers in Windows 10, google how to install unsigned drivers in Win10
2. Open the folder you extracted SP Flashtool and run it as administrator.
3. Unzip the rom file you downloaded.
4. Inside the folder of your unzipped rom file, look for a file similar to XXXXXXXXXX_scatter_file.txt
5. Load this in the SP Flashtool (click downlad tab, then scatter loading, load this file in there. It should load your rom you will see some colours, etc...
The tricky part:
Assuming you have correctly installed the drivers:
1. turn off the device (well if bricked it is turned off all ready) just make sure, and in SP Flashtool click options and 'with battery'.
2. Click the green download button on SP Flashtool.
3. Hold down the Vol down key on your device and connect it to a usb port.
4. If you see a red line and continue to yellow, all is probably good! Don't let go of the vol - button until yellow line reaches 100%
B. Root and TWRP recovery
This requires that you have or download:
a. platform tools (adb and fastboot)
b. a twrp.img (image file) for the lenovo TB3-850F copied to external SD Card and platform tools folder (google is... useful )
c. latest supersu.zip (flashable) copied to an external SD CARD
d. busybox.apk
Steps:
1. Grab tablet, go to settings ---> about tablet ---> click version number 7 times to enable developer options
2. From settings again click developer options and enable OEM Unlocking and usb debugging
3. Navigate in the platform tools folder. While holding SHIFT right click and select open commandline here (or similar)
4. Connect tablet to PC and in the command line issue: adb devices
If a weird number shows up and says device on the left you are all good to continue.
5. Now on the command prompt again issue: adb reboot bootloader
Your tablet should now reboot to fastboot (big Android, laying down)
6. Issue command: fastboot oem unlock (also check tablet screen for confirmation)
Wait a little bit and reboot your tablet. (should work with holding the power key down for a little longer than 10 seconds. If not hold down volume key and power button for the same amount of time - tested and working)
**At this point it is ESSENTIAL to leave the tablet to fully boot. The bootloader unlock triggers a FACTORY RESET which you must leave to complete and set up your tablet from the beginning.
** It is also ESSENTIAL to complete the boot and set up cycle because, after the automatic factory reset you will need to RE-ENABLE developer options and usb debugging. Once you are done continue to 7.
7. In the platform tools folder copy the twrp.img (you should have downloaded earlier, check upwards... )
8. Open the command line again and type:
a. adb reboot bootloader
b. fastboot boot twrp.img
** This will load up TWRP recovery only for this boot time.
****BE EXTRA CAUTIUS TO -NOT- ALLOW twrp to make modifications. Essential! Should you do otherwise go back to how to unbrick your tablet.
9. Choose install, and install supersu.zip.
10. Choose reboot to system and allow complete boot cycle! Essential!
11. Your tablet should now be rooted. However to succesfully flash the twrp recovery you need to have Busybox installed. Download as .apk and install it (at the time of writing this I believe Busybox 54 is the latest version).
12. Once installed back to the windows terminal and issue:
a. adb reboot bootloader
b. fastboot boot twrp.img
ONCE AGAIN - DO -NOT- ALLOW twrp to make modifications!!!!!
13. From you external SD Card install twrp.img, select recovery when prompted.
14. Reboot to system and enjoy!!!!
Note : Install an app that makes it easy to boot to recovery. (I personally use root essentials - Trying the combination keys did nothing for me, or just poped up the chinese options menu. That does not mean the recovery has not been installed correctly. Booting to recovery from rootessential menu, boots straight to twrp)
All you will need and credits:
https://drive.google.com/drive/fold...ourcekey=0-SDvJaXtWWk-TY9B53ct8dw&usp=sharing (thanks button, thanks button, thanks button!!! )
Results:
(it is in Greek, but you get the idea )
Hope I have helped! Happy playing with the commands and whole process! :good:
Lastly, if you get stuck at any point, you can either use this thread or PM me for further advice, explanation and/or any kind of assistance.
Note: Special thanks to @MotoJunkie01 for actually taking the time to further help people on this thread, as unfortunately I do not currently have the time to do so myself. It is worth checking out @MotoJunkie01 's threads also. There, you can find very useful and updated information.

Thank you for the encouragement. I am in hopes that we can eventually get a dedicated device forum for the tb3-850f. I truly believe this tablet has the potential for plenty of future development.
@r&xp I love you so much, I was in the same predicament as you and you helped get my tablet running again. Just wanted to mention, I had to hold volume down when plugging in the USB for the SPFT step instead of volume up. THANK YOU AGAAAAAAAAAAIN <3

Glad it worked for you. Isn' t it like a really good feeling when you actually see your bricked device boot correctly for the first time after you had almost deemed it unusable???
(also... a... small request... could you please click on that thingy... you know... that ehhh... thanks button??? :angel::angel:)
Just an update, since damaging my TB3-850F, I have since ordered another unit from Office Depot which is due to be delivered Monday or Tuesday. Once it arrives, I'll finish my TWRP flashable stock 6.0 ROM for this device and start back on the modified stock ROM.

Thanks for the comment!!! :silly:
Glad it worked for you. Isn' t it like a really good feeling when you actually see your bricked device boot correctly for the first time after you had almost deemed it unusable???
(also... a... small request... could you please click on that thingy... you know... that ehhh... thanks button??? :angel::angel:)

Looking forward to it. I picked mine up from walmart just yesterday for using as a google maps/car media center
My Lenovo Tab 3 replacement finally arrived in the mail. I'll be picking up where I left off on compiling both unmodified stock and custom stock-based ROMs for this tablet.
On my modified stock based ROM, I'm considering the implementation of Substratum (Root Ver) for theming, but I would like to get the input of other device owners first. So far, I have debloated, deodexed and zipaligned the OS. I am including the modified/patched boot image with SuperSU v2.79 SR3 binaries installed for systemless root, Nova Launcher, Pixel Icon Pack, BusyBox v1.26.2 binaries pre-injected in /su/xbin/, and Kernel Adiutor-Mod installed in /system/apps/ for user defined adjustments to the stock kernel and governors.
You guys please give me input on what you would like included in the ROM. Thanks

I had a Lenovo Tab3 that bricked during the initial set up and this saved me for having an expensive paperweight! The process worked like a charm. You ROCK!

Try again to get TWRP installed to your /recovery partition or, alternatively, try to simply boot into TWRP from fastboot with the fastboot boot twrp.img command. It is common for members to experience some difficulty in installing custom recovery on this device. It has been my experience that most members are successful the second time around.
Thanks MotorJunkie!! But mine after was saved from brick from this thread, i was rooted it also by your instructions from other thread.. Now the gps from GoogleMap doesn't determine the location (even the location already turned on ) ... Plus i couldn't check the systemupdate ( it says connection network failed even i was connecting to wifi already) ...
What should i do, or do you know how to fix it?

System updates (OTAs) won't install on rooted operating systems. To install an OTA, you must have unmodified stock /boot, /system, and /recovery partitions installed. On the GPS issue, go to Settings, Apps, and ensure Google Maps has been granted location access permission.
Hi ...
I followed this guide but during the unbricking' I unplugged the device from USB (since I could not see any input on device or indication in SP Flash Tool).
Now the device will not turn on at all (previously I would see the Lenovo Logo splash screen but then it would just stay at this screen. Now i do not see anything).
When I plug into computer by USB, it causes my computer to freeze up (Windows 10).
Any ideas or is this now completely bricked? (hard bricked).

It sounds like a hard brick. I can't speak for the OP, @r&xp on this, so you may want to get his advice. Have you tried the OP's methods of using your hardware buttons for forcing the device into adb/fastboot recognition? I think this is your only chance of recovering it. By it not powering on, from my experience, a bootloader or bootloader dependent partition has been corrupted, thus hard bricking the tablet.

Hello, I'll weigh in on this one. There are multiple threads above the TB3-850F on this forum and also another forum.
I initially followed a different thread and instructions which caused my problem. Notably do not allow TWRP write access !!! This mistake caused the soft-brick.
Anyone following any other advice about TB3-850F or downloading any other image BEWARe. Only follow the advice in this thread by r&xp:
https://forum.xda-developers.com/android/help/lenovo-tab-3-8-tb3-850f-unbrick-root-t3598727
Following this advice I now restored original image and then rooted in just a few hours.. Thank you r&xp for the good advice. :laugh:
