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

Flashing Instructions:
This is a fiddly process so some perseverance might be required. It will work in the end. From user reports it seems to work most smoothly on the 32bit version of Windows XP.
Instructions:
- Firmware must be flashed using a Windows application called LiveSuite.
- Once downloaded, and before attaching your tablet to your PC, run the file 'LiveSuitPack_version_1.09_20111101.exe' from within the Livesuit folder. This should install a new device on your system (VID_1f3a_PID_efe8). This device may show with an exclamation mark in Windows Device Manager, this doesn't matter and can be ignored.
- Now download the firmware image you want to install. After decompressing the archive you will end up with a .img file (e.g. 'sun4i_crane_xxx.img'). This is the firmware/ROM image that you are going to flash (or copy) to the tablet.
- Without attaching your tablet to your PC run 'LiveSuit.exe' from within the Livesuit folder. You should get an application with 6 icons.
- You will be asked if you want to be guided through the process, select no.
- Click on the leftmost icon (a cube), browse to your downloaded firmware image, and select it.
- Now attach your tablet to your PC by USB cable whilst holding down the volume+ button on the top. Straight after attaching the cable, and whilst still holding down the volume+ button, start pressing the tablet power button repeatedly. This (slightly frenzied) procedure puts the tablet into update mode.
- After a few seconds you will be asked if you want to perform a forced firmware update. Select yes. You will be asked if you're sure. Select yes.
- The update will start. You can release volume+ at this point.
- The update should take approx 3 minutes to complete. You will see a % complete progress bar during the process and will get a dialog saying OK when it's done.
- Turn your tablet on and you will have the new firmware.

thanks for reply
my device is china MT6572 with android 4.2.2
I have use a very very very superb tool named "MtkDroidTools v2.48" and bricked my newly purchage tablet.
1. I click on root and happy thing is that tablet got rooted. wow
2. I have created backup from this tool and after few minutes, many *.img backup files are created on my pc and my tab's sdcard. wow again
3. After restarting the tab it restarting again & again and not booting. really a "heart attacking wow".
I have tried following steps
1. In default "android stock recovery 3e" trying to restore backup files and got message "installation aborted" everytime. same message from using "adb sideload command"
2. creating a scatter file from this tool and load backup in "SP_Flash_Tool_v5.1343.01" tool. but no any tool connect my tab. it says no device.
3. only "adb sideload" from stock recovery has the way to connect to the pc. but I don't know which kind of files are used at there??
During the backup process a log file created by MtkDroidTools has attached for details information.
then plz tell me. what I do for get again a "relaxed wow"??
Load scatter file and back up files in SP Flash tool. Power your tablet off, hit download button in SP Flash tool then connect tab to pc.
If you have the preloader driver installed SP flash tool should connect and start flashing firmware to phone. Do you hear the connecting sound when you connect powered off tablet to pc? If not, you may need to press and hold Vol Down, Vol up, or menu button while connecting tab to pc.
Hope this helps and good luck!

Ok, no need to hit a combo of buttons, only 1 button you need to press while connecting tab to PC. Please retry following the directions from my last post again
Yes, preloader will only show for a few seconds in device manager before it turns off. Preloader is only for reflashing firmware. When it enables itself, it is looking for the SP FT (or other firmware flashing programs) to be there to catch it, if not preloader shuts itself off.. Your download of SP Flash Tool should have included the needed preloader drivers. Then you load files in SP FT and hit download button then connect tab to PC.

Thank you very very very very much. Finally I have got a wow.
After many efforts, I resolved the tablet booting issue. It is possible due to only your valuable suggestion.
steps are here:
1. connect tab to pc & installing preloader usb drivers.
2. getting VID & PID of tablet usb connection.
3. modifying "SP FT settings files" with new values of my tab.
4. creating a scatter file from droid tool & load in SP FT.
5. Flashing backup to the tab successfully.
You are such a genius. I have been wasted a lot of time since a week for getting the right answer. During this period I had connected to many android experts at many sites. but no satisfaction answer.
And u are really amazing. You have got the real problem in only three conversation. really great.
Well I m a windows expert. If u feel any technical problem regarding servers or windows, ask me, I will try my best.
I am launching a website soon named "GeniusPepoleofWorld.com". Many technical experts & genius people will listed there in different categories like Android experts, Windows experts, Linux Experts, Robotics Experts, Electronics xtra xtra. I want to add you at top there in Android Expert list. Now site is under constructions. I want to know your name & personal mail-id like gmail etc. When I will finish my site, I will inform you.
One more thing I want to know that "what is the use of stock recovery & adb sideload, which files types are used with it?"
Plz plz reply this with your name and mail-id.
Thanks a lot again

I am happy to hear it worked for you. Nice job Raj! I am just passing on the knowledge I learned here on XDA (Thank @rua1 he made MTK DroidTools and without that tool alot of folks with MTK devices wouldn't have root, stock firmware back up files, or working recovery
Anyhow, as for your last 2 questions. Stock recovery is used for flashing officially signed update files from your device manufacturer (If they were to make an update that is lol) This is how all android devices are able to accept ota updates, they download the file to phone/tablet then reboot into recovery and then it flashes the downloaded file to the device.
Adb sideload allows you to connect the device to a PC and then upload a firmware file to device to be flashed via recovery instead of downloading it directly to the phone. This is useful if you had an officially signed stock firmware file for your device stored on your pc. Some custom recoveries also allow you to use adb sideload but since you have stock recovery you would be restricted to using only officially signed files.
Say for instance you were not able to get your device to boot properly, you would just need to boot tablet into recovery mode and then choose adb sideload. At this point you would connect tab to PC and then put your firmware file in the same folder you have adb.exe in. (Let's call the firmware file "firmware.zip" in this example) Then open command prompt in same folder that adb.exe is in and type "adb sideload firmware.zip" this would push the firmware.zip file to the device then flash it for you.
Since you were able to use MTK Droidtools to get root then make a back up, you should be able to also use it to make a custom recovery for your device too. When you made the back up, it will usually make 2 back ups, one on your pc that you use SP FT to flash files and restore your device then it also makes a back up on your devices sd card that is flashed through custom recovery to restore your device. This would make restoring your device pretty easy if you need to do so again and it will also allow you to restore without needing a PC to do it.
Hope this helps!

I've got the exact same problem with my phone... My phone, Celkon A15 (Indian brand) also has the same chipset number and while trying to root using MTKdroids tool, I have managed to get it in the boot looping stage.
I'm just curious on how you managed to get the pre-loader installed for this? I CAN NOT get the SP Flash tools to detect my phone for the life of me. Also, when I load my scatter file, it has the "PRELOADER" section in RED... and when I try to upload the preloader.bin from my backup files, it says... "Load file "*path name*" fail!"
I am still struggling to understand how the SP Flash tool works and if it would be able to get my phone alive again (well it did help you out, so I am bit optimistic).
Please HELP!

Hi
1. First you have connect your device to pc.
2. you have to open the device manager and keep your eyes on a new hardware found at device manager, when you start up your device.
3. Preloader will only show for a few seconds in device manager before it turns off.
3. install preloader drivers.
4. open SP Flash tool and load scatter file and set path for your backup files.
5. Click download button and reboot your device.
6. Software will catch your device and finally backup will be restored to your device.
I too have got same problem, i have infocus m2 with mt6582, i rooted with kingroot n used mtk droid tools for backup.after backup i tried to modify boot img and install cwm using mtk tools but now it wont boot up, nor it enters recovery mode, i tried to flash stock boot and recovery img through sp flashtool but its giving error (2004), plz help me plzzzz....
so my stock dell venue 8 3840 would just load into a black screen, so I decided to follow the instructions aOSS_A195.pdf (can't submit links) to attempt to unbrick it
Starting from step A. Flash A195 image to the tablet I was doing quite well A.12 Double click file “P802_flash_device_wifi_only.bat” or “P802_flash_device_lte.bat” in SW image folder. The following CMD window will show up, and begin to flash OS system image. At this step the Cmd couldn't find the tablet so after several attempts to fix it and failed attempts at googling the problem I made the poor decision to skip this step and go to.
Step: B. Rooting and bootloader unlocking process using OTA package this step was going fairly well up to 5) Select recovery (3rd item from list), and use volume down button to navigate to it and select it by pressing power button. Upon clicking recovery the screen showed nothing but the usb symbol restarted several times and it would only go to the usb symbol no more bios menu or anything.
So I'm starting to panic a little at this point so I decide ok let me start back over at step A. Flash A195 image to the tablet. Ok good I have the bios menu back maybe I can get to the recovery screen from this one... Nope permanent usb screen again ****... Ok no problem I'll just go back to step A. Flash A195 image to the tablet and it will fix it again.... Nope permanent usb screen that I can't get to go away this time. So no what am I screwed can it be fixed?
I do not particular care about rooting it I just want it to function stock would be fine with me. Any help will be greatly appreciated.
Update after several more redos of step " A. Flash A195 image to the tablet" I finally got it to stop showing the USB and go back to the droidboot screen. I'm afraid to try to access recovery again in fear that I will once again get stuck with the eternal usb symbol. So please advise me on the best course of action I should take from here.
http://opensource.dell.com/releases/Venue_8_3840_Merrifield/
before do step A12, copy 4file( adb.exe fastboot.exe adbwinapi.dll adbwinusbapi.dll) ( http://opensource.dell.com/releases/Venue_8_3840_Merrifield/developer-edition/FlashTool/fastboot/ ) and paste into the extracted image folder, after this, run the .bat file
thanks huynhlam, that got me a little further with step a12. Now I've run into a new issue though. Just get waiting for device. I've tried reinstalling all the drivers but it seems to only be detected properly when its off.
When its on the driver has a explanation mark next to it and it says "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)".
From my understanding it needs to be on during step a12 but I can't get it to do anything other then waiting for device at the moment any advice?
i'm done with windows 7 x64 , if you are runing on higher windows version eg : windws8 ,i hear something about install the driver ... like this http://forum.xda-developers.com/showpost.php?p=62068965&postcount=2 or google eg : https://learn.sparkfun.com/tutorial...abling-signed-driver-enforcement-on-windows-8
Also on windows 7 64x
maybe your driver issue, try uninstall driver, disable driver signature and re install driver.
Hello there,my Wave 8 HD+ stuck in android boot logo. I downloaded the wave8hd_20151105_v1.8 update thru wireless update and install, it says error in installing:
E:error in /mnt/internal_sd/adupsfota/update.zip
(Status 7)
Installation aborted.
My tablet is now in recovery mode and cant move highlight due to no volume buttons available,i can only select the "reboot system now" option.

I did use the software Rockchip Batch Tool v1.7 provided by Bluewave in their website,install the 33GT driver for my tab(Tab can now be seen by my PC and download the correct firmware update(using my serial number at the back of said tablet) still provided by Bluewave,but still error in upgrade..
i just want to know how to change the highlighted option in recovery mode so i can wipe/factory reset my Tablet disregarding the said update..
there is an option in recovery mode "recover system from back up" but i could not choose to highlight and select the option..
any alternatives for the volume button??Btw,the firmware provided by Bluewave is in ".img" format,not "zip"..
thank you so much for your reply..

hello, jho_zep, thank you so much for your reply, i am now able to move the highlight to select using my mouse, but still when i try to update from ADB, it tells me to send package to the device etc.. and i also tried to press the power button, it wont reboot the system, it would only shutdown the system.. another thing, i still cant get rid of the system update. " installing system update" then error comes in, my android is down.. i tried wipe date/ factory reset, still nothing.
Thanks in advance
Do you already solve your problem? because I have now the same problem as this.
I have pressed the wireless update then it restarted and it says an Error status 7.
I don't know what to do and how to deal with this problem.
can you help me?
My nextbook tablet rk3026 has a partition named metadata that holds the recovery boot commands. You could possibly try to wipe it and do a factory reset. I don't think it actually gets mounted so you would need to find a file the same size as the partition and dd to it. Or back up your system with rockchip flash tool then using a hex editor replace all data in metadata image with zeros. Obviously be careful. Here is a tool download with included guide credits to finless at freaktab(not sure if he is here at xda) for posting it.
http://freaktab.com/forum/developme...p-your-rk-device-rom-with-the-new-rk-2-1-tool
as always BACKUP and know if you don't do it correctly you may get a brick.
thank you for the response Destructos. but that solution won't help for my freakin weird tab 33gt HD+.
I get frustrated now
Problem solved
first thing to do is make sure that you have already installed the rkchip_usb driver in your computer.
What are the requirements?
1st of course your Tablet and Cable Connector
2nd Finless ROM Flash Tool v1.37
3rd Rokchip BatchTool v1.7
4th the update image/firmware for your Bluewave 8 HD+ that is downloadable from their official website
Steps:
1. off your tablet and connect it to the computer
2. open the Finless Rom Flash, uncheck all the boxes
3. turn ON your Tablet (be attentive) and while the blue screen is starting you may NOTICE that the ROM FLASH TOOL detected your device, it says "RKAndroid Mass Storage USB". when you have read that, press immediately the "Reboot Flash mode" and your device will in black screen. but ROM Flash tool still detected your device as "RKAndroid Mass Storage USB "
4. Open the Batch Tool, (you must know how to use it) find your image, then you will notice that the CONNECTED DEVICES below have color green, in that case you may now Click UPGRADE. wait for a minute and booooom, you device is functionable again.
have a feedback if it is helpful.
P.S.
before I go to that steps, when I am stuck in RECOVERY MODE of my device, I Click the Recover from BACKUP then my tablet restarts and it turns to BOOTLOOP and repeatedly saying NO COMMAND.

Why is it, when I do this, my tablet can't be detected by the software? I'm stuck on recovery mode. When it's on the blue logo, still does nothing.
I can only see my device when I look for it on Device Manager under Android Phone. Why is that? It doesn't show the "Other Devices". I've installed the driver but to no avail, still fails me. Please help. Thanks!
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.

Good guide. This tablet has temperamental steps involved with custom recovery and root. This guide gives a good outline of those steps. Here is a link to my thread for Stock Android 6.0 firmware for this tablet for members who need a stock ROM.

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.

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

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:
