I did my search before posting this, so I'm sorry if this has been already resolved but I couldn't find solution to this.
I've a Kindle HDX 8.9 64GB wifi model, it was rooted installed SU, installed safestrap on it and had google play store and gapps working on it., I was too busy so left it device as it is and never used it. Recently got free and noticed it was downloading update. I remembered reading that update breaks Root so switched off device as I panicked and then turned it on in airplane mode. I came here and saw what could be done to prevent update. Tried firewall with IP tables that didn't help as download of update resumed after I turned airplane mode off. Then I did more search did below changes
I renamed otacerts.zip to otacerts.zip.old in /etc/security/
I renamed com.amazon.dcp.apk to com.amazon.dcp.apk.old in /system/app/
along with above changes I made changes suggested in this thread http://forum.xda-developers.com/showthread.php?t=2678600
"edit build.prop
ro.build.version.number=999999999"
After doing all these changes, update stopped and started giving me error of unable to check update. I was all happy. Started using device normally and everything was fine till I rebooted device and that's when it messed up.
Tablet starts normally with Kindle fire logo and then comes Safestrap menu with options to continue or go into recovery. I clicked continue as usual and it just sits there with grey screen. Doesn't do anything at all from there on. I rebooted again and was able to go into recovery mode but I never took backup (I know dumb of me) so there was nothing I could do there. I tried to turn on adb sideload in recovery but it kept attempting to turn on but never did. When kindle is in grey screen its been detected on Laptop. In device manager device is detected 2 places as shown in picture attached, One under other devices with shows android device with yellow triangle on it and also under portable devices as MTP usb device. Though I'm unable to see it detected in file system. I've kindle drivers already installed.
I'm not sure renaming those files messed my system up or changing build prop messed it up. But I'm unable to find solution to fix this mess.
I would really appreciate help as I'm in pretty tight position here. Device can't be returned to amazon as I'm in India now. So only option I got is to repair it somehow or its $500 down the drain
UPDATE : ADB detects Kindle as emulator-5554 device. May be its a good sign? :\ again any help would be appreciated.

try rebooting the device and go into safestrap recovery and when you hear the driver try to load in windows go to device manager,it should be listed as mtp under portable devices,uninstall that driver do not reboot,,unplug device and then plug it right back in it should try to load the driver as kind fire hdx but fails,when it is done check device manager for the kindle fire with the triangle on it and click update driver,then click browse my computer for driver software,then click let me pick from a list of device drivers on my computer,then scroll down until you see kindle fire click it and then click ADB ANDROID user interface and the click next,if a box pops up saying something about drivers might not be compatible just click yes to install,when its done you will have kindle fire in device manager and in adb it should say what ever you device is and then RECOVERY after in adb then you can push the files needed

I have bought a second-hand Galaxy Tab which will not keep changes in settings or any uploaded files or IDs after switch off and restart.
This means I cannot root it, as any uploaded files with Odin are lost on restart.
Can anyone help me please? I have tried all the usual resets to no avail.

Hmm, I thought this might intrigue the experts, but to no avail.
Where the hell do I go for an answer to this problem: rooting cannot be done as flashed files will be lost on reboot.

Hi. Thanks for getting back.
I have gone up and down the forums for ideas. (for over 3 days now).
The story so far:
I have tried to flash the overcome .tar file for my model using odin 1.83, but get a red box and a Fail! : error 0X140005. I followed the Overcome guide VERY carefully, got the yellow COM box, put the right file in the right box, but when I hit the start button, it fails.
I can boot into "Download". I have tried restore after wiping the cache.
With normal power up, the OS seems to work partially, in that I can do all the things I want to do, but all the settings, WiFi passwords, uploaded files etc disappear on reboot, and any uninstalled programmes re-appear. It seems that it won't permanently write to, or erase from, "long term" memory.
Before this,I have done a full cache wipe and factory restore but no difference.
Thoughts:
a) I am wondering if a previous occupant has tinkered with it and messed up the memory partitions? is it all RAM?
b) As it is stuck, it is stuck with USB debugging disabled. this will be maintained on reboot: could this interfere with Odin?
Any suggestions would be very, very gratefully accepted.
FG

Dude i ask this in another forum you posted, did you use odin to install recovery or not? if you did then just boot into recovery and wipe all - then flash galaxytab or any flashable roms that way.

As I said in the second paragraph: I tried to use odin to install recovery, but got the big red square. The file did not transfer.

No your second paragraph said you flashed overcome. Not recovery
So if odin is not installing recovery can you boot into fastboot? Power off then press power n volume down then go to fastboot mode and install recovery that way. Check this thread for info. . http://www.galaxytabforums.net/forum/galaxy-tab-10-1-general-discussions/1044-my-galaxy-tab-10-1-wont-power-up.html
Then flash a cwm flashable ROM

hi again; well no success so far.
- I downloaded and installed SDK (software development kit: for other noobs like me)
- I downloaded and installed recovery.img, and installed the google USB drivers from the extras
- I checked that the fastboot.exe, adb.exe (android debug bridge) and recovery.img were all in the platform tools folder.
- got into "download":- odin mode
- plugged in the tab and tried to launch "adb start-server" from cmd screen
(I was in the right directory at the command line), but no cigar: nada.
- I went back and did the PDAnet routine, but still no joy, no devices shown
there were no error messages either, which made me think the usb was not communicating with the tab.
To try this out I used Kies to transfer a photo file to the tab, and viewed on the tab it after disconnecting, so tranfers do take place.
Sure enough, after rebooting, the file was gone, like all the other settings and changes made in the past.
I also tried adb when the tablet was on and I had checked usb debugging. In this case, adb recognised the device and returned the serial number.
It does not do this when in cwm mode as it will not remember to keep debugging on when I power down.
Any other ideas anyone? can I switch debugging on from the command line before I try to recover?
FG, (now getting a sore head and worrying if I have p***d my money up the wall.)
Funny, when things get really tough, the helpers disappear.
Still no solution.
Oh dear: silence again.

AFAIK you won't get a response in ADB when the tablet is in download mode but you should when the tablet is in CWM recovery mode.
If it were me I'd odin a stock factory recovery to the device and a stock factory rom for it. Then i'd boot into stock recovery and do the factory reset to see if that cleans things up. You should probably link to the source of the files you're downloading as well as provide specific model of your device so people can verify that you're flashing the right files.
I'm totally confused by your steps here
you went to odin mode and used adb? or did you go into fastboot and adb the recovery?
step by step here
a quick overview of it is to get your tab into ODIN mode and use ODIN to reload a copy of the stock image to your tab. This erases all of your previous data but you can reinstall those later. But at least it gets you back to a working tab - Note this is for the 7510 - the wifi tab
1) Download this file - MEGAUPLOAD - The leading online storage and file delivery service
2) extract the file
you should have the following
a file called GT-P7510_USB_Driver_v1_3_2360_0-Escape - this file is the USB driver for your PC, if you don't have the driver installed already, run this
a folder named Odin3 v1.85 - this contains the ODIN executable file
a folder named KME Odin - which contains 2 files - android_fastboot_emmc_full_p4_16G_32G.pit" and a "P7510XABKME_P7510UEKME_HOME.tar"
3) Power down the tab
4) press POWER and Volume Down at the same time until it powers up and you should see 2 logos - USB and triangle (note the retail wifi version might show 2 different logos, android on right and bag on left - left is recovery and right is Odin/download)
5) press volume down to move the selection to the triangle (or the icon on the right)
6) press volume up to lock in selection. You are now in ODIN/download mode
assuming all your drivers are installed to your PC, plug in the tab via the USB to your PC
run the ODIN executable
only Auto-reboot and F.reset Time should be ticked
after a minute, the ID:Com box should turn yellow -if not you may have driver issues (try this driver http://drivers.softpedia.com/progDo...SB-Driver-for-Windows-x86-Download-96692.html)
7) tick PDA and click the PDA button and navigate to the KME Odin folder and select "P7510XABKME_P7510UEKME_HOME.tar"
8) select the PIT button and navigate to the KME Odin folder and select the "android_fastboot_emmc_full_p4_16G_32G.pit"
9) Select START
it should start writing the image to your tab and once done, should reboot you back into stock
in case you want to go ahead and flash 3.2 -
use this pit file - http://forum.xda-developers.com/attachment.php?attachmentid=784889&d=1321486916
and use this for the PDA http://hotfile.com/dl/135008863/06c...EKMM_P7510XABKMM_P7510UEKMM.rar.html?expire=1
if it asks you for Password for the 3,2 file use : sampro.pl
when resorting to odin and first booting up, you might get asked for a password, the way around this is to
a) power off,
b) press power n volume down until you get 2 icons left is recovery right is download.
c) press volume down to select recovery icon then volume up to lock it, you should then see the recovery menu
d) then use volume buttons until wipe data/factory reset is highlighted press power to do it
e)after its done wiping, select reboot n you should be ready
Now the key thing here is installing the right drivers - after installing teh driver, connect the tab and see if the drivers are installed - go to your pc control panel and check if you get a triangle with an exclamation point. If there is, right click on it and select update driver, then manually choose device - navigate through and find the Android or samsung device (cant remember the name off the top of my head)
if you get stuck, report on which part you got stuck on - currently it seems like you're mixing and matching different steps so it is a little confusing

- I went back and did the PDAnet routine, but still no joy, no devices shown
there were no error messages either, which made me think the usb was not communicating with the tab.
To try this out I used Kies to transfer a photo file to the tab, and viewed on the tab it after disconnecting, so tranfers do take place.
Sure enough, after rebooting, the file was gone, like all the other settings and changes made in the past.
I also tried adb when the tablet was on and I had checked usb debugging. In this case, adb recognised the device and returned the serial number.
It does not do this when in cwm mode as it will not remember to keep debugging on when I power down.
Any other ideas anyone? can I switch debugging on from the command line before I try to recover?
FG, (now getting a sore head and worrying if I have p***d my money up the wall.)

Hi again, sorry to confuse you but I was following your suggestions in post #7 of this thread. when I got to step 5 of that post, I got no response from the device: installed PDAnet to get over the driver issue. and no joy.
When trying to install .tar or PIT files I get a big red box, even though the yellow COM box looks good.
When trying the data erase/ factory reset option in the "Download" mode, I get the error message "Can't access to /system/csc/XEU/system.
Steps 7/8/9 in your post above do not work: I have tried them a few times.
Sorry, I have run out of options, and thank you for your help.
Okay guys here's the dealio-
I recently got my transformer prime and I *loved* it. It came pre-loaded with the .21 version of ICS, which can't be rooted as of now so I downgraded to stock .15 with a modified ViperMod and then rooted and installed CWM. Next, I installed the Gummy custom ROM onto my prime (still .15). Well, I started to experience some weird -probably ROM related- issues and I ended up deciding to flash back to stock. ...BIG MISTAKE on my part I found out! I used the modified ViperMod to flash back to the stock .15 and it ran through the process but stopped at the ASUS boot logo with the little loading circle going around and around and around. First I let it sit for a VERY long time-stuck on boot. Then, I tried turning it off and back on-stuck on boot. Next, I tried pushing down the little recovery button-stuck on boot. I tried booting into CWM, but obviously, since I flashed back to the stock .15, all I get is the android guy laying in his side with the red triangle.
I am really really hoping that this is not a hard brick because the error that people are describing is the tablet stuck in the screen with "EeePad" in the middle and then getting something about an "unrecoverable bootloader error". My tablet boots past the EeePad screen and there is no error message-just the endless loading circle.
I am hoping that one of you smart guys could have a clue on how to revive my tablet. Any help would be greatly appreciated, and maybe I can buy you a beer if you bring my baby back to life
Here is a picture of what it looks like (circle is still spinning):

so you can get into recovery? I saw you said you tried to flash cm9 again. if you caught in a bootloop, jemaine made a zip file you can flash to get you out of it. you have to search for it though in developement section. does your computer still recognize your prime when you hook it up to your computer? you may need to adb commands into prime.
good luck getting it back running.

I no longer have cwm installed, it is just the stock recovery so I cannot install any .zip's. Also, when I plug the tablet in wile its on the Asus loading screen, the computer DOES recognize it. Maybe there is some way to get into it and reflash?
Any suggestions guys?

When you say your pc can see the prime can you see it with adb? If not go here:
http://forum.xda-developers.com/showthread.php?t=1426502
Once you have adb figured out you should be able to reflash recovery. See this thread:
http://forum.xda-developers.com/showthread.php?t=1576937
I used method 2. You will need to push the blob file to your prime using adb. Hope that helps.
Won't turn off and stuck on Boot screen PANIC!!!!
I'm running CM9 nightlies on my 64gb TF201 and have had no issues with it. I'm using GooManger and Teamwin for recovery and have not had any issues in that department either. Until now.
So 2 days ago a nightly was released that I flashed with out issues. The updated ROM however wanted to open the virtual keyboard when I started typing so I decided to revert back. I did this by just flashing an earlier released nightly. It went through the process and then restarted. The boot screen came on and then never left. If I try and turn it off it just restarts. I can't get it into recovery but I can get into fastboot. However I don't have a little Android symbol just the wipe data and USB. I don't have a backup on my computer that I can push through. I flashed CWM recovery through fastboot in hopes of then being able to get into recovery but with no luck. I used transformerprimerecovery.zip followed all the instructions got an "OK" and "finished" on CMD. At the same time the little progress bar on the TF showed that it did something but no change with my condition.
When I'm connected with fastboot it doesn't show up on my computer as I found to be expected. In device manager Android Phone is listed and when I click on it ASUS Android Bootloader Interface shows up stating device is working properly. If I open CMD and type "cd" it just replies C:\users\Josh>. I tried to wipe data to see if it would and it said it did but still no change. I've been reading for the past two days and haven't found the same set of problems yet. I've found similar issues but not all together.
Please if anybody has a suggestion for me I would be most Thankful. I've not had any luck with my searches
Thanks

I haven't been able to try this yet for I seem to be having ADB issues. SDK is updated and current and I have the latest universal driver setup. I show up in device manager but not in the CMD prompt.

I seem to be falling further down the rabbit hole. I mentioned above that I was able to flash CWM recovery via fastboot was not able to access it. I tried the same process with TeamWin recovery. It just stated that the specified path could not be found. So I'm losing features now.

When you are trying to flash anything in adb or in fastboot, put the file in the same folder as those .exe files. Manytimes it is a typing mistake on the path that kills you. Also remember to add the.zip at the end of the file name if applicable.

No luck. I've tried rearranging all the files associated with adb and fastboot I can think of. I've opened the CMD window from about every file as well as from the start menu and I can't get CMD prompt to recognize the tablet. The tablet allows me to get to the point where it states that it is "starting fastboot USB download protocol". Device manager shows Android Phone > ASUS Android Bootloader Interface. And when I remove the device it shows it listed as "fastboot device". I'm stumped on getting into CMD and can't do anything until I do. It just stays on the boot screen until I force it off. And if I'm not holding down the volume up button when I do it, it just recycles on. I've found post regarding the boot screen locked on but everybody has been able to fix it through a properly functioning fastboot/ADB.

The command window should be opened from the same window (folder) you have adb.exe or fastboot.exe in otherwise it isn't going to work unless you have the exact path which is easy to kame a mistake on. I would try the following:
If your not on twrp I would fastboot install it first.
Install universal naked driver
Download and unzip nvflash file
In the folder window where adb.exe is, press and hold shift, and right click and select open command prompt here.
Now do adb devices
You should see you device
put you rom in the same folder and push it to the table
reboot to recovery and install
first off, i just wanted to state, before i get ripped into, i have spend the last 1.5 days reading everything i can find on any forum that comes back with search results for my issue. i've tried numerous drivers, different PC's, even a Linux Live CD system.
I cannot get my PC (win 7, 32 bit) to see my TF201 via ADB.
It is installed in the device manager with the "universal naked driver 0.7", and shows up as "Asus Transformer Prime ADB Interface". But whenever i try to connect via ADB to run the fix in this thread - http://forum.xda-developers.com/showthread.php?t=1514088 - i cannot see the device.
I have tried all of the mount/unmount options in CWM. nothing is working for me.
is there anyone that has run into this? And if so, have you found a resolution?
sorry if i'm coming off as the typical noob here, but i really have put in time researching the issue and attempting other fix-it routes before posting up a help thread.
Thanks!!

Update****
I was able to get it out of the boot loop, so that it will boot to the splash screen. well following instructions i've found online, when in CWM, i connected through ADB and pushed a copy of cm9.zip up to the internal storage.
yet, whenever i choose "install from zip" in CWM, it never finds the zip file.
i have done it a few times now and it says it copies up completely, but never actually shows up.
syntax i'm using: adb push cm9filename.zip "/sdcard/cm9filename.zip"
it takes about two minutes and gives me confirmation that it pushed x amount of bytes of data for the file, and says its done. I then go back to the tablet in CWM and choose install from sdcard, and it says there are no files.
I'm about ready to throw this thing in the trash and be done with it......
First of all make a small text file and zip it up for a test file that wont take long to push.
Now type adb push test.zip /data/media/
look if the file is showing where you go to install a rom.
If it is showing then push the rom to the same place then install it

I am having the same exact problem. It started when I tried to restore my stock backup that I made using CWM 5.8.2.0 coming from the CM rom. I am stuck in the CWM recovery screen and cant get ADB to see the TF Prime. I just get error: device not found. How did you manage to push a zip if ADB wasn't seeing your device? I have been looking for a fix for the last week now.

the problem is whenever it try to fastboot it just keeps saying waiting for device. I can put my TF prime in fastoot mode when I power on while holding down on vol it just goes right to CWM recovery and any adb command gives me no device found and I tried APX mode (holding vol up during power on) and tried to use NVFlash but that just gives me an error device not recognized. I have all the drivers installed. I used the naked drivers .7 and have cleared out all the old drivers too.

No, you hold Vol down + power then when the first screen with sentences appears you release everything DON'T touch anything, after 5 secondes you will end in a screen with three icons, with volume down youu select the usb icon in the middle, then volume up.
This procedure works even on locked devices except that in this case you don't have the usb icon, only the factory reset and cold reboot ones. So it's impossible you don't obtai this screen, it's hardware coded.
It is confusing but just keep trying till you get it!! Once there go to the TWRP site they have the file and the fastboot commands all set in a guide.
I have exactly the same problem than you.
I had the fastboot/adb connection (I used to push the rom by adb), but i tried to install a wrong version on gapps. Since then, I'm stock in the recovery mode without adb/fastboot connection.
If you find a solution for that, pleaze post it !!

I have a blind N10 on bootloader that is it doesnt show anything on fastboot mode but it does go there. I researched and found other people with similar problem http://rootzwiki.com/topic/37629-bootloader-fastboot-weirdness/ . However they managed to unlock the device by clicking the vol+ once and then power key as I also saw on youtube videos. IT WORKED. and then it went downhill. it got stuck on bootloop. SO i tried to go into fastboot again and it went and then pressed vol+ twice to go into recovery and there was a android with "!" red sign on middle.
and of course it won't boot. So I tried to use the Wugs toolkit, put it on back to stock with bootloop option. and it started to do its work, but got stuck at the sending bootloader (1280KB) sign for more than 10-15 mins. I pressed the power button and it failed that step saying too many links and wugs kit continued the process got stuck again and then completed and my device still goes to fastboot, but cant go into recovery anymore I think as it shows blank screen. Please mind that I am still blind on the screen and nothing comes. my only way of knowing it goes to fastboot is through cmd line. PLEASE HELP, dont wanna brick this.
Is there any way to ODIN it. I cant find online any ODIN insturctions? help help
I cant even turn it off now! Its always going to fastboot. Please help

I think that's a good thing, if you can get to Fastboot then I would say to forget about the toolkits and just download the latest Google MantaRay image from here https://dl.google.com/dl/android/aosp/mantaray-jwr66y-factory-3d8252dd.tgz
Make sure your Android SDK is updated, unzip the downloaded file once and copy the contents to your Fastboot folder, shift/right click inside your fastboot folder and select "open command window here" then type "fastboot devices" and make sure your device id is shown, after that just type in your cmd window "flash-all.bat" and let it do its magic. If everything goes well by the time it completes you will have a factory restored Nexus10 and then you can start the hacking all over again.
Good Luck! and remember when in doubt, just ask.

Hi ricco333
thanks for the reply. I have updated the SDK and tried to run the command as you mentioned. However it is the same thing. Its getting stuck at sending bootloader. I am attaching a screenshot here. it stays there until i press ctrl+c. then it tries to continue and gets stuck again at sending boot. which is the second screenshot.
Is there any other way to restore factory image. i thought samsung devices had ODIN system. Thanks again for the reply.
Try connecting the Nexus to a different USB port, also try another USB cable, as a last resort I will go as far as using a different PC, based on your screenshots it is being recognized but my guess is that it is having a problem writing the new partitions.
Erik
Also try re downloading the stock images...
Maybe you have a corrupted file.
Have you tried using the Nexus 10 Toolkit?

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:

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.

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.
**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 1: 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)
Note 2: If you encounter problems installing Windows drivers in Windows 10, google how to install unsigned drivers in Win10
I apologize for not being able to post links, but I believe the required software is not particularly hard to find.
Hope I have helped! Happy playing with the commands and whole process! I will continue to help as much as I can :good:

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, I appreciate your comment. I was really enthusiastic to read that you are working on a pure Stock Android 6.0 ROM for this device! Will definitely be waiting for that!
Thank you again!

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

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:)
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

Hi all!!
This is for all the people who managed to softbrick (or hardbrick) their Lenovo Tab 3 8' (TB3-850F) tablets!

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:
