#If U Successfully unlocked ur Bootloader then,
place the recovery image in the same directory as fastboot.
Open a terminal on your PC and reboot the device into fastboot mode by typing
adb reboot bootloader
or by using the hardware key combination
(press & hold Volume down and power button When phone is off)
#Once the device is in fastboot mode, verify your PC sees the device by typing
fastboot devices
If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine.
#Flash recovery onto your device by entering the following command:
fastboot flash recovery your_recovery_image.img
where the latter part is the filename of the recovery image.
Once the flash completes successfully, reboot the device into recovery to verify the installation. Boot to recovery instructions: Hold Volume Down & Power simultaneously. On the next screen use Volume Down to scroll to recovery and then use Volume Up to select.

I successfully installed twrp recovery system but I can't do any backup, the system reboot in the process...

It's not my fault.... seems a bug of twrp
XT 1068 UK
TWRP 2.8.0.1 Back up fails to both internal and external SD.
When external selected, backup starts but after 10 to 30 seconds it reboots the device. It starts to back up files and then just reboots. If I don't select compress backup, then it starts to backup more files before it reboots. Seems to be time related. Also tried unplugging while backing up and same issue.
Folders get created in all cases for external SD but data files. Not sure where the log files would get stored. Suspect they don't get created as the system reboots during the backup

[Q] Corrupt Bootloader

Please help!
I am currently trying to root my TF701t on Jellybean but I appear to have corrupted my bootloader. I can boot into the bootloader and do a system wipe and boot Andoid, but when I select the RCK option I end up with the Android image on its back.
I have downloaded CWM 6.0.4.6 and tried to apply the recovery.img file via Minimal ADB and Fastboot command prompt only to be greeted with "cannot load "recovery.img" Result too large".
To be clear the system boots normally and fuctions perfectly - this is strictly a bootloader issue which has been unlocked successfully.
Any help would be greatly appreciated and apologies in advance if either the solution to this has been posted elsewhere or I have not given you the information you require to help.
Many thanks,
East
You need to fastboot recovery from the bootloader.
When you reboot into the bootloader do not select RCK. RCK is the recovery, I don't think the default one can do anything, you just get the android on it's back.
So it should be reboot into bootloader and then don't touch your tablet.
Then from your pc fastboot flash recovery recovery.img
Make sure you are also on a 4.3 bootloader before you fastboot flash CWM 6.0.4.6.
The instructions above are correct
To flash a recovery you need to have the fastboot.exe file and cwm recovery.img file in the same folder.
Right click + shift on the folder they are in and choose open command prompt here
Boot into the Bootloader by either booting with the Power and Volume Down Buttons held down until you get the 3 icons or by typing the following into the command prompt.
Code:
adb reboot bootloader
Then type the following commands to flash the recovery image:
Code:
fastboot flash recovery recovery.img
fastboot reboot-bootloader
Start the recovery by making sure the RCK icon is highlighted (use volume down to move) and push volume up to select.

In Windows 7 you can just navigate to the folder with explorer and in the address bar type cmd and hit enter
Opens a command prompt in the correct folder
Doh!
Thank You
Well.......this is very embarrassing.
I have rooted and installed custom roms on my last 3 phones including the my new Nexus 5 without any problems at all. I simply followed the instructions posted by the developers. At the same time I used to take the piss out of the other posters who raised queries because they hadn't followed the instructions. What do I do? Exactly that.
Please accept my apologies sbdags as it is your rom I am installing and thank you to You & Sleeepy2 for posting polite and prompt replys without having a go at me for not following your instructions.
Problem solved I am now rooted!
Thank you again.

So I had unlocked my bootloader. rooted, and install TWRP, I tried installing cm11 which was in my sdcard, I factory reset, but when I when to look for the zip file it didn't come up in my ext_sdcard.... I did made a backup on twrp, but I don't have an os currently install, Idk how to boot into my recovery, I have the fastboot drivers install and when I put the phone in fastboot mode and run adb shell I get error: device not found.

To boot to recovery:
Power off device
Press and hold Power + Volume Down
As soon as the LG logo appears, quickly release Power and press and hold Power again until you see a screen titled "Factory data reset"
Use volume keys to scroll down to "Yes". Press Power to select
Do the same as before one more time
You will then boot in to recovery
As for TWRP:
Make sure you're using the latest version.
Up towards the top of the TWRP Install page there is a line with a gray background the starts with "Storage:". Press it and then select Internal storage or external sdcard. Now press "Ok" at the bottom of the screen. Now browse to the folder where your zip is.
Now for your fastboot ADB thing. The adb executable cannot communicate with a device in fastboot mode. That's what the fastboot executable is for. Where you used "adb devices" you should have used "fastboot devices". ADB is for when your device is booted in normal device mode or in recovery mode and the recovery supports USB debugging. Unfortunately you can't boot to recovery thru fastboot.

Thank you for your help, i was able to bot into recovery and flash my back up.... and then i was able to install cm11.

Red Status bar for TWRP (OSPREY). FIXED!!!!

The TWRP red status bar is a small problem and easy to fix. It is caused mainly because you haven't accepted the 'Write permission" dialog box in the startup. In my case, I couldn't flash anything onto my phone and showed the message "FAILED" so i had done the following steps:
Before going into this. You have to make a backup of the files and apps on your phone. A working custom/stock ROM
Minimal ADB and Fastboot must be installed and the latest Motorola Drivers should also be installed.
1. Get a stock recovery, follow this link to get that: https://www.gammerson.com/2015/08/download-and-flash-stock-recovery-in-moto-g-3rd-gen.html
2.After flashing the stock recovery you have to boot onto your recovery. You will see the "No command" window. There you have to press Volume up+power button simultaneously for 5 or more times.
3.Click on Wipe data/factory reset.
4.After that boot onto your custom/stock rom. Finish the initial startup on your phone. Make sure that USB Debugging and USB Tethering is ON(Hotspot settings)
5.Now boot into fastboot mode.
6.Download the latest TWRP from: https://forum.xda-developers.com/devdb/project/?id=11051#downloads and paste into the Minimal ADB folder which can be found in C://Program Files (x86)/Minimal ADB and Fastboot
7.Now in the cmd window. Type the following codes:
adb devices
which will show whether your device is properly connected to the PC or not
fastboot flash recovery twrp.img
and voila TWRP will prompt you for the "Write Permission" once again, properly read it and swipe for confirmation. xD

I have done all the steps but For some reason twrp is not installed and i still have the stock recovery. Please help
That's because the above only boots TWRP to root but does not install it. To install TWRP, when in booted with TWRP, you need to transfer the TWRP img to the tablet storage and then install it while in TWRP.
it is important to show the pathway to the file TWRP-3.0.2_TB-X103F-beta.img in the command line, like:
C:\Users\Public\Documents\My Videos\TWRP-3.0.2_TB-X103F-beta.img
Sorry for this newbie question.
Which part of the above rooting steps is rooting my tablet, what is TWRP doing and why do I need to install the SuperSU app?
During my first try I didn't boot the TWRP image rather I flashed it. But that didn't help at all.
After booting the TWRP image I was able to flash the SuperSU app.
The stock recovery is still in use.
Thanks in advance.
Read the steps carefully and follow the steps, it is a tested successfull strategy. To get deep knowlege about the background processes, please read the threads elsewhere in Web.

Hi everyone. I just want to clarify something about this procedure There's a lot of people being confused on how to get into FASTBOOT on some things, and that's stopping them getting anywhere from the beginning.
The Lenovo TB-X103F tablet doesn't have a way of booting directly into FASTBOOT. Turning the tablet On while holding either volume key and the On button doesn't do it directly. . . . . Firstly, there's 3 buttons on the tablet, I call them VOL- VOL+ PWR (again, that's just to clarify things 100%)
here's what must be done (well it's this way on the 3 I have on my desk, so I assume all TB-X103F tablets are the same) . . . . .
1) Turn the tablet off completely.
2) Press & hold the VOL+ button (the middle of the 3 buttons).
3) Press & hold the PWR button, release the PWR button as soon as anything appears on screen - Keep holding VOL+ button.
4) After about 8 seconds the familiar green android lay down will appear. Then, your recovery menu will appear.
5) Release the VOL+ button anytime now.
6) Press either VOL button to select BOOTLOADER on the menu (Bootloader is the same as FASTBOOT on this menu, that's where the confusion lies for many users).
7) Got Bootloader selected? now press PWR and let the tablet reboot itself.
8) it will show the LENOVO logo, and appear to be stuck - it isn't It's in Fastboot mode.
9) Plug in your USB to PC cable, and it'll install appropriate drivers on the PC (hopefully eh?).
10) Once the drivers are installed, test it by getting a Command Prompt in your ADB/FASTBOOT folder on your PC . . . .
11) type the command FASTBOOT DEVICES It should show you that your device is connected, if it shows no devices then either it didn't install the drivers, or something
else is wrong (there's about 30 things that can have gone wrong here, too many to go through in this quick guide).
12) The tablet will stay in FASTBOOT/BOOTLOADER mode until you turn it off (or the battery goes flat lol). So stay calm, there's no rush
I've mentioned about there being no rush, because if you choose ADB connecting from the recovery menu, it disconnects automatically after about 5 minutes -
This is Important to know because it can disconnect while you're pushing/pulling files from the tablet, and cause really nasty problems. Bad design eh?
But we're in Fastboot mode, so nothing to worry about like that

Successful root
It was hard, but I had finally had done it. I had figured it out it is easier just to go to the command prompt (I ran it under admin) and "cd C:/adb" (where you installed the adb fastboot software) while having the TWRP image file being placed there. I only wished that I had done it sooner. And for those who are new to the custom recovery it can be overwealming, but with patience and going through the files in the file explorer to find your main storage would lead you to the SuperSU file and successfully root your device.
I flashed TWRP...now what? I can't find any instructions on how to reboot into TWRP. I got into some sort of Chinese menu (PWR + VOL-) but I'm pretty sure this is the device test menu.
So I did the "fastboot oem unlock-go" command and adb said ok but my tablet just went to a black screen and won't turn on now and I'm not sure why. I also heard the Windows USB disconnect sound when i did it.
Would this work with the TB-X104F running 8.1?
Since a few months my tablet is stuck with the 'password changed, wait....' message. I had hoped that I could overcome this with the steps mentioned here. But unfortunately not
I can't start it anymore, so I'm not sure if it is in developers mode or not. Also, plugging the device in my mac didn't let it download the drivers.
Too bad, because when it was working it was a great tablet, now it's just a expensive drawer filler

"fastboot devices"
fastboot shows notting
lenovo seems to have killed these tablets from the old lady next doors experience.. no wifi, no adb, no fastboot, no qualcomm, just unknown device, which loads NOTHING, no drivers work!!!

Yes, this is called a soft brick.
You can solve the problem by doing the following:
-Your bootloader should be unlocked, and I think you've already unlocked it since you were trying to flash a custom ROM.
-You need to have a STOCK ROM of your exact phone model, this is different from TWRP backup, search google for your phone model's stock rom and download.
-You should have Fastboot and ADB installed on your pc.
-boot to fastboot mode (volume up+power, then navigate to fastboot mode).
-connect your phone to pc with USB cable
-open the folder where you have downloaded the minimal adb and fastboot, and open cmd window there with right lick or click cmd-here.exe
-now type fastboot devices, and there should be an alphanumeric code. This means your device is connected. If it is not showing up, try downloading 'minimal adb and fastboot tool' and clicking cmd-here.exe.
-In the stock rom file, there will be a file called 'firmware', and inside it there should be these files: 'system.img' 'recovery.img' 'cache.img' 'userdata.img' 'boot.img'
-Copy all 5 of these, then go to the folder where you have adb and fastboot, go inside that folder( to the place where you have all the adb and fastboot files like adbWinApi.dll). Now paste the 5 files here.
-open cmd window again, and type the following:
1) fastboot erase boot
2) fastboot flash boot boot.img
3)fastboot erase system
4)fastboot flash system system.img
5)fastboot erase recovery
6)fastboot flash recovery recovery.img
7)fastboot erase cache
8)fastboot flash cache cache.img
9)fastboot erase userdata (this may be called data, if fastboot shows an error message, type data instead)
10)fastboot flash userdata userdata.img
and you are done, this should enable you to restore your phone.
If you are unable to access your bootloader, try flashing your stock ROM with SP Flash tool (if you have a mediatek device). You have to have your stock ROM downloaded on your pc. Connect phone to pc via usb, open SP Flash tool, select your firmware file in the topmost box, and in the box beneath that, select the file ending in scatter.txt from your firmware file. Uncheck 'preloader' if it shows up on your screen, then click 'download'. Do not disconnect your phone during the process. When it is finished, there will be a green tick, and you should be able to restart your device.
