I have root and recovery on my ascend Ascend D1 (u9500) (NOT Quad!)
First i followed steps 1-7 here:
[not allowed to post link since i have to few posts]
ht tp : / / johnnyparanoia.blogspot . se/2012/06/how-to-root-huawei-ascend-p1-u9200.html
In step one i chose ("just the tools...")
To get ClockWorkMod Recovery i had to experiment a bit. Note that i believe that using CWM might hinder the possibilities to install official updates from Huawei.
How i did i wrote in a comment to the blog post previously mentioned.
I managed to install recovery (ClockWorkMod Recovery v5.8.4.5) after a lot of messing around.
First i installed Android Control (to c:\AndroidControl)
I downloaded cwm_touch_recovery_viva_beta.img and put it in c:\AndroidControl
Then i went into the phones download mode (or whatever it is called) by:
a: Turning off phone and wait a while
b: Hold Volume down and connect usb cable from computer
Now a new device shows up called Blaze. No driver could be identified. (in W7x64)
I Selected it in Device Manager and forced it to use "Android adapter ADB Interface" (I selected: Update driver software / Browse my computer... / Let me pick from a list... / Mobile phone (I think it was) / Android adapter ADB Interface).
I had the driver availible there. This might be from installing HiSuite earlier.
Now i started the command prompt (cmd) and went to c:\AndroidControl.
Then i ran the commands:
"fastboot devices" (to confirm that the device was identified. If no device is found an error will be thrown.)
"fastboot flash recovery cwm_touch_recovery_viva_beta.img"
"fastboot reboot"
Baseband version is: "IMC1202_20120620_PENTA"
Kernel version is: 3.0.8-00028-gf1d0793 [email protected] #1
Build number is: U9500-1V100R001C00B215
Kurbits!
Actually I did tried hard to follow your steps but it dostn't work. Luckily, after a long day trying i'm now successfully got my D1 a CWM (ClockWorkMod Recovery v5.8.4.5).
However, still i can't ROOT it, i've been tried the UnlockRoot but no chance. Can you tell me how you have it ROOTED?
I plan to flash an international version but the process always aborted. Is there any trick to do it? The CWM always look for UPDATE.ZIP while the firmware that I've downloaded has only UPDATE.APP
Do you have any suggestions on how this can be accomplished?
Thanks!

Hi. So you have tried steps 1-7 from ht tp : / / johnnyparanoia.blogspot . se/2012/06/how-to-root-huawei-ascend-p1-u9200.html [not allowed to post link since i have to few posts]
Where does it go wrong? I´ll qoute the steps for reference only.
The url referred in step one is: h ttp://w ww.mediafire.com/?7pdfh11ue8ykyk6
Step 1 - Download ...just the tools here - b113 b115 root u9200[Nixing] Tools Only and extract to your desktop.
Step 2 - Enable USB debugging on your phone - Settings -> Developer options -> USB debugging and plug it into your PC
Step 3 - Run hwadb.exe and let it finish.
Step 4 - Run ubl.exe and wait for it to finish.
Step 5 - Disconnect your phone from your PC and Reboot.
Step 6 - Check to see if Superuser has been installed on your phone.
Step 7 - If you find Superuser in your menu, Congratulations your phone is rooted

I got it to work without problem. If you can specify where it goes wrong could you post a screenshot of what happens or be more specific about which step that does not seem to work.
Kurbits!
Thanks for the reply. I've successfully rooted it now but not with the steps in the URL u provided. What I did was tried to fix the permission and root it via CWM.
Anyway, what I really wanna do now is to flash it with international firmware offered in Huawei download page for D1. But the thing is that the firmware is come with UPDATE.APP instead of UPDATE.ZIP and I did try to rename it but no chance, always aborted.
Do you have any idea how to get it done?
Cheers

the automated process from this thread did not work on my D1, but this manual process did:
download mempodroid and su from
http://forum.xda-developers.com/showpost.php?p=21756513&postcount=1
follow all instructions in that post up to the mempodroid command (1st 4)
execute mempodroid with these args instead (copied from the ubl.exe tool posted by the OP)
Code:
./mempodroid 0xd734 0xad9f sh
execute the rest of the commands from the mempodroid root post (up to the adb reboot)
Hey did you try the Bin4ry method? its so simple and took me seconds to root!
I am on the quad but im sure it should work through this restore method!

Reflashing U9500 to stock / Upgrading HUAWEI firmware
I have been searching these and other forums for a while trying to determine how to (a) update my CWM & rooted U9500 to the newest huawei build (221), and (b) return the phone entirely to stock (remove root & CWM). The main issue with either is that with CWM installed I couldn't figure out how to install Huawei's firmware UPDATE.APP files retrieved from their website. Here's how I got that to work:
I used the current firmware from Huawei: U9500-1,Android 4.0,V100R001C00B221,General Version (I can't post links)
Extract the HUAWEI zip and copy the dload folder (containing UPDATE.APP) to a micro sd card
Download split_updata.pl & crc binary from modaco.com forum (google "Repacking UPDATA.APP")
Run the split_updata.pl script with the path to UPDATE.APP as a command line argument. It should extract a bunch of unknown files to the output directory.
unknown_file.7 (should be 5697536 bytes) is the official recovery partition. This is what you will replace CWM with. You can rename it to recovery.img, or just use the created filename when flashing.
Boot phone in download mode:
* Power off
* Hold POWER & VOLUME DOWN buttons
* Release both when Huawei logo appears
* Phone should not continue booting or enter CWM
Run fastboot devices and make sure something is listed (mine only printed a bunch of question marks, but it worked fine)
Run fastboot flash recovery recovery.img
Run fastboot reboot
After the phone boots up normally, go to settings -> storage -> software upgrade -> sd card upgade and click confirm.
This will reboot into the official recovery image and start the upgrade process. This will also remove CWM, root/superuser, and any other changes to the OS you have made.
If you were just looking to upgrade, you can reflash CWM and/or root the phone again. If you were looking to return to stock, you can then reboot into Android and run the factory reset option.

You need to correctly install the drivers for both adb and fastboot.
It would be a nightmare on a 64bit Windows system, but it's quite easy on Linux/MacOS systems.

Hello guys,
I am pretty new to this stuff. I have just got LG P500 early this year, my friend helped me root this phone with CyanogenMod (7.1.0-RC1-Thunderg-KANG) and the Build number was SonyGenMod v1.2 Final. Not sure if this information is needed but I really want to go back to normal settings or the best settings as I don't really know how to root/unroot or update stuff.
I just want to use the updated version of Android Market. Right now, it is very annoying that I can't go online on WIFI because I can't update apps or go in Google Play. As it comes up with some errors.
Again, I'm pretty new to this stuff. I am not experienced so I need a clear step on how to fix this situation. I need your help if possible. Not sure if this is the right place to ask. Feel free to move this thread.
Model: LG P500
Android Version: 2.3.5
Baseband Version: V07u-000-000-MAR-23-2009
Mod Version: CyanogenMod-7.1.0-RC1-Thunderg-KANG
Build number: SonyGenMod v1.2 Final
Please let me know if you need any other information to solve this.

Firstly, forget about unrooting because nobody would dare to unroot any Custom ROMs. Or if you really wanted to unroot, install a LG P500 stock Android firmware.
And I guess you've wiped data/cache/dalvik-cache in recovery in order to get correct functioning of the ROM. Not doing that would arise problems.
Android Market (now, Google Play) updates itself when an internet connection is active in phone. I'm not sure about your Wi-Fi problem, its better to ask that in your device-specific forum.
If you really need to start from beginning :
- Enter recovery, Wipe Data/cache/dalvik-cache/battery stats
- And install the CyanogenMod ROM again (Assuming you know how to install)

Reboot phone and update Superuser from Market.
These rooting instructions works fine on LG Optimus One, it can have some problems while updating superuser, kept force closing, but after restart, it will work fine.
If something went wrong when trying to flash a recovery image, for example when flashing CyanogenMod or ClockWorkMod. It happened to me several times so I tried to learn to revive it without reflashing the original firmware. Note: This tutorial works only if recovery is the only one broken. (If the ROM itself is broken, then that's a subject for another tut.) In this case, the most logical thing to do is just reflash the recovery image. So how do you do it in fastboot mode? Here's how:
Symptom
You tried flashing a custom recovery like ClockWorkMod or Thunderg, or you flashed an incorrect ROM, and when you rebooted, it showed this screen:
Code:
fastboot mode started
udc_start()
and the phone stays there. When you plugin the phone to your computer's USB, it is detected and the screen has this display:
Code:
fastboot mode started
udc.start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
You will need
1) Your PC and your USB cable for the phone
2) USB drivers for your phone (use B2C from LG).
3) Android SDK (download from here)
4) Java, required to run the SDK (but right now I am not sure if this is required to run fastboot!)
5) ClockWorkMod or AmonRa Recovery.
Here's what to do
1) Assuming phone is turned on in fastboot mode, plug it in to the USB of your PC. You will know that it is detected if you see the the lines "suspend", "reset" and whatnot on the phone's screen.
2) Extract the recovery image from the zipfile downloaded from step#5 above (e.g. LGp500-recovery-v12.img). Place the image file in the same folder where fastboot.exe is (usually in the tools\ folder in the SDK). For your convenience, rename the img file as recovery.img
3) Fire up your command prompt and cd to the directory where fastboot.exe is located. Then type the following command:
Code:
fastboot erase recovery
Once you get the confirmation that it was successful, type this:
Code:
fastboot flash recovery recovery.img
Once you get the success confirmation, reboot the phone, or you can also type (optional):
Code:
fastboot reboot
The phone will reboot itself, and with any luck you should be able to go back to your same old Android bootscreen. Note that no settings were modified here, so this is extremely useful for those who do not want a clean slate after a fastboot nightmare.
Also, note that if this is successful, you can now boot to recovery with the usual button-combos, thus enabling you to flash ROMs and other recovery zips.
Note: On some SDK versions, fastboot may not be included. For your convenience, I have attached the fastboot binary I got from my downloaded SDK. I have also attached AdbWinApi.dll which some user reported is missing in the SDK. Place the DLL in the same folder where fastboot.exe is located.

Good day! Sorry for my English.
I'm flash MTS firmware and my Mediapad now with locked fastboot.
I tried to flash official firware from Huawei site.
I put folder dload with update.zip and unlmt.cfg in root of sdcard and start flashing.
After this I saw yellow android and message something "Syncronize bla-bla-bla" (this message was some seconds)
Then came message to reboot.
After reboot I saw: "Image verify failed! Please update to the authorized image."
I tried to flash many official and unofficial firmwares, but get one result - "Image verify failed! Please update to the authorized image." I used sdcards 2,8,32 gb
If I press Power and Volume+ I get this message.
If I press Power and Volume- I get locked fastboot.
Also this message came if no sdcard in device.
I can't flash other recovery, because fastboot is locked
I can't boot system and use my device.
Help please.
Solved
1. Attach device to Linux computer via USB
2. Press both volume keys about 30 seconds
3. fdisk -l with root user
4. See in file huawei_partition.xml from official firmware zip
5. Use dd command for flash images sbl*.mbn boot.img recovery.img to partitions accordance id from huawei_partition.xml and fdisk -l
6. reboot and flash dload using stock recovery.

This method can use for unbrick.
good info
I'm still new to springboard/mediapad but if this really allows raw flash access the method should be in an unbricking guide or developer FAQ!!!

My device was currently experiencing anything like you, ie fastboot mode locked due to failed flashing, and now can not do flashing via fastboot or flashing normal use file "dload" on sd card
Can you explain in greater detail the step flashing in linux, I tried to use ubuntu. but I do not understand using the dd command.
I've come to the step $ fdisk-l
and the device is read as / dev/sdc2
please explain the next step ...
whether the file "update.zip" should be extracted in the folder "home" when running the dd command?
Hi ,

Intel Android Devices Root / Temp CWM Session
CLICK HERE DONATE NOW : AND MAKE MY LIFE EASIER BY HELPING BUY ME AN UNLOCKED DEVICE
Tethered Temporary CWM Recovery Session :
Note : This is a Temporary CWM Recovery Session for some Intel Devices with locked bootloaders, This recovery is not installed to the devices and has to be launched from a computer ( tethered ) each time you need to access the CWM Recovery. . .
WARNING : This Temporary CWM Recovery Session is for some Intel Devices with locked boot loaders , it is not intended for installing custom roms as if the devices has a locked bootloader the device will fail to boot the unsigned images
Intel Fastboot Tethered Temporary Recovery Session Launcher download :
IntelAndroid-FBRL-01-17-2015.7z
Changes :
Fixed recovery.fstab generation should work for almost every device i can't guarantee for all devices if device uses some funky mounting point or a block device other than /dev/block/mmcblk1xx but after reviewing more than 50 different recovery.fstab from various fastboot.img i think i covered all the common intel devices.
If needed you can always include your own custom recovery.fstab in the recovery.zip
fstab generation automatically marks reserved / hidden partitions fs_types as emmc to prevent recursive mount loops this has the added benefit for devices that use traditional mount points for boot / recovery they are now able to be backed up too.
fixed adb on devices that don't have adbd as a service in fastboot.img init.rc
Note : WORKING
backing up to external storage / internal storage
unsigned .zip installation
adb root shell
you tell me
Note : KNOWN BUGS
installing using adb side-loading of zips doesn't work and breaks adb
you tell me
Generic Instructions for use better instructions coming later just wanted to get the thread up :
notes :
make sure you have downloaded and installed the adb / fastboot drivers for your device . . .
make sure you have enabled developer options / adb debugging under settings on your device . . .
make sure you have download the latest : UPDATE-SuperSU-vX.Xx.zip and place it on your internal or external_sd
1 : download and extract IntelAndroid-FBRL-01-17-2015.7z some where on your computer.
2 : double click the launcher.bat file to start , type " ACCEPT " case sensitive without quotes to continue
check that the tool is reporting as either :
DEVICE STATUS: ADB-ONLINE
DEVICE STATUS: FASTBOOT-ONLINE
If " DEVICE STATUS: UNKNOWN " please check your cable connection and driver installation under Windows Device Manager
If " DEVICE STATUS: UNAUTHORIZED " please check if your devices is displaying an authorization prompt be sure to check Always allow from this computer and then press ok
3 : select the trigger to launch the Temporary CWM Recovery Session support fastboot oem triggers are :
T1 oem startftm ( very few devices support this command , but its the original used so )
devices supported : coming soon
T2 oem backup_factory ( limited devices support this command )
devices supported : coming soon
T3 oem stop_partitioning ( should work on alot of kitkat builds )
devices supported : coming soon
4 : after selecting the trigger your device should reboot in to fastboot and begin to copy files to your device
note : if your device hangs at the waiting-for-device screen and you see droidboot CMD Waiting on your devices double check that the fastboot driver installed correctly.
note : if you see unknown oem command the trigger isn't supported by your device.
5 : The temporary cwm recovery session should be started at this point select install zip from the recovery menu using vol up / vol down to navigate and power to select
6 : select install zip from sdcard / external_sd depending on where you placed the file and select the UPDATE-SuperSU-vX.Xx.zip you downloaded earlier
7 : confirm the installation
8 : after install completes reboot your device
note :
some devices have limited space under /system and the supersu app wont install
if you don't see the supersu app on your device attempt to install it from the playstore
more than likely the su binary installed correctly but there want enough room on the device for the app.
This recovery uses the CWM Recovery @vampirefo built for the Dell Venue 8 3830 NoModem original thread : Dell Venue 8, CWM, unsecure boot/recovery

T3 don't be in a rush! It says failed but then will load anyways. Wait for it! Use the very first link here. To root ¿ well when in recovery, flash superuser zip. Wait for it! Reboot from the cwm menu. In windows you can leave the device on normal and when you execute the launcher bat it'll put the tab in its proper mode. Just choose T3 and flash super user zip and then reboot.
it's android. i am using a windows 7 machine...
it boots into droidboot and just sits at cmd waiting.... i waited about 10 minutes. i am missing a step. can someone create a youtube video to follow by? i am willing to donate 10 bucks. thanks

Sorry I didn't get back sooner , the issue is the fastboot driver installed as an adb driver seems to happen to most Intel devices.
Anyways with the device booted into droidboot open windows device manager select the adb device and right click and update driver software. Select browse my computer. select let me pick. then select the bootloader driver .
No donation required gotta get back to playing with my little girl i'll add pics later.
ok thanks man, pics will help me, i'm not too bright.
i will try that. as the device is waiting on droidboot, i will open device manager, and load the driver (where can i download this driver?)
Thanks for trying to help me guys. I give up. Too hard.
Yes! I did it! the social concepts step was what i was missing... thanks man i am rooted
Perfect!!

I follow all the steps and I sucessfull root my device (Dell Venue 8 HSPA+ 3830-A30P)
Tks!!!
Here is full rooting method which i share with you from Dell Venue 8 3840 Manual. I hope this is easiest and result-oriented method:
Download and install the Intel Phone Flash Tool Lite on your PC. Also download the venue_3840_droidboots.zip.
Run Intel Phone Flash Tool as administrator and connect Dell Venue 8 to PC using OEM USB cable.
Browse and choose venue_3840_droidboots.zip file.
Select ‘1-502_droidboot_and_firmware.xml‘ from the drop down menu and click on start.
Reboot Dell Venue 3840.

1. Phone Flash Tool
- Install USB drivers (if on Windows)
- Install Phone Flash Tool Lite
- Run PFT, open "Dell_Venue_8_7840_Lollipop_5.0.2_qs_rd_opensource-blankphone-userdebug-1397.zip"
- Select "flash-DD0_BB.xml" and flash it
- Tablet will restart in bootloader, flashing isn't done yet, so wait
- Sometimes it can be hard to get the progress bar past 4% before things fail. Just keep trying if this happens, it'll randomly work.
2. Tethered Recovery ("IntelAndroid-FBRL-07-24-2015.7z")
- Unpack the system image (from "system.zip") to a convenient directory
- With tablet still in Bootloader mode, open app, select CWM mode, then T4
- Phone will restart in CWM once everything loads
3. Flash system
- Go to the mounts / format area, format "/system" and then unmount it
- Insert Micro SD card and mount it
- Format "/external_sd"
- On computer, type "adb push <path-to-system.img> /external_sd/", wait for it to finish
- When finished, type "adb shell" to enter the device shell (make sure the prompt is "~ #" to make sure you are root (or type "whoami" at the prompt to confirm root)
- (If not root, restart to bootloader and trigger the tethered recovery again. You should be root this time.)
- Type in "dd if=/external_sd/system.img of=/dev/block/by-name/system" and wait for it to finish
- When finished, type "exit" on your computer to close the shell
- Reboot the device (to bootloader)
4. Flash boot
- Back on the computer, type in "fastboot devices" to confirm the tablet is connected
- Type "fastboot flash boot <path-to-boot.img" in order to flash the boot
5. Reboot
- On the device, tell it to boot normally
- Wait. It's a first-boot so it's gonna be a bit slow as the cache is built and whatnot
6. Enjoy!
7. (Optional) Root using the Update-SU.zip using the tethered mode again.
I noticed that it won't take any updates so this leaves you vulnerable to the Stagefright bug. It also sometimes boots to the bootloader and waits to you to select normal boot. Sorry. (Anyone know how to help?)

Any news? I'm stuck at 5.0.2. I wonder if it's possible to port cyanogenmod.
Hey there! Super helpful tutorial and most helpful so far that I found! However, my tablet just goes black after I press Normal Boot and just stays that way. Also when performing ADB Shell (Mac) for some reason it stays in the shell for few seconds and goes back. Any ideas why that might be happening? On top of that I can only enter the shell command really quickly so I have no idea when it finishes copying system.img across... Any help would be appreciated!
Hi guys,
does this method flash the 7840 with a 5.0.2 image or with a 5.1 one?
Thanks
I tried and I can reply to myself: it restores a clean 5.0.2 image ...
EDIT: xposed framework work perfectly on 5.0.2 . I'm perfectly happy with it now
Guys, please disable Driver Signature before installing ANYTHING on your PC to mod, change or rescue your DELL 7840
Intels Platform Flash Tool wont flash ( ifwi error ), and tethered recovery wont upload through bootloader
took me a while to realise itself, even though i did it many many times, after not doing for couple of years, i almost forgott that you need to allow unsigned driver installatino before
have grait ****,
Iko
What if you can't boot into fastboot mode? When I try to boot into fastboot, the screen only shows a battery logo with a question mark inside. I saw that there's a fix for this problem on Intel processor devices like the Zenfone and Del Venue 8 3840 using xFSTK Downloader. But that requires dnx_PRQ.bin and droidboot.img.POS.bin, which I don't Dell ever released. Any solved this problem before?
Flash tool wont detect tablet
So i would love to try this out, im new to this whole thing and have the problem that the flashtool cant find my device
Any Tips ?
I'm unable to get further then 3%, at best. my tablet starts and shows USB icon, nothing more.
anybody has solved this ever ? has unbricked this model ? I have searched everywhere, not found any one person who solved this with usb ICON showing.
please help, if you know how to .
Intel Flashing
You need to use 'On Demand Flash" option from Intel Flash Tool. Start flashing from computer and continue on your device.
For Venue 7840
- Unplug
- Power off
- Press and hold both Volume keys
- Plug USB cable
- Release keys
It will start loading automatically
I've use Intel Flash Tool Lite 5.3.2

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.

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:
