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.

#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.

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
Hi,
I am really desperate! I turned on my rooted Asus MeMO Pad 7 ME176CX after several months of no use, but apps/services won't load (loads of error messages, all apps/services stopped etc.) like it was obsolete or screwed up. So I unrooted it and the issue got worse!
There is a Asus demo app in the notification bar that disables WIFI and software reset and says to plug in the power adapter (no difference, it won't go away).
1) I copied the necessary files to my memory card (to get rid of the Asus demo app as per other threads) but once I insert the memory card, even though it is recognized, it says no files present.
2) I did a hard reset with Vol - (or +, tried both) and Power but nothing happens (no recovery screen, it just stays black).
3) I removed the battery & waited 10 mins, no difference.
4) I formatted a card to FAT32 and copied the cleardata.zip unzipped files from Asus then rebooted pressing just Power but it just reboots normally like the card is not inserted.
Now basically the tablet shows a few apps (Calendar, Gallery etc.) and nothing else.
I cannot connect to wifi, bluetooth does not work, the memory card says no files present, vol + power does not work, cleardata trick did not work, I cannot send it back under warranty (ex-rooted) ... what else can I do??????
Many thanks!
Reboot into Droidboot (Volume Down + Power IIRC, could be up), boot the Temporary TWRP (http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096), flash ROM
After a few experiments gone wrong I have now bricked the tablet for good (erased all data).
I can ONLY go from the dead droid to 'Android system recovery' which shows:
- reboot
- apply update from ADB
- wipe data
- wide cache
After 'wiping' the only option available is 'Apply update from ADB', so I installed ADB on my Mac and downloaded a few ROMs from the Asus site (even though their page says ME176C not ME176CX, but there is no ME176CX page there).
If I run adb devices from the terminal I see nothing. Only if I select 'Apply update from ADB' on the tablet I see the device from terminal, I believe it opens a bridge to the computer only with this option running. The command 'fastboot devices' never shows anything regardless.
I run 'adb sideload update.zip' (tried with several ROMS) but it always fails AFTER the transfer (either with messages 'status 0' or 'end of footer not 0xFFFF' etc.).
So now I am stuck with adb sideload never working, is there anything else I can do????

Well, theres quite a lot of options do recover your tablet, before doing anyhing, if you have access to adb, then you should do: download .17 rom and extract it, after extracting go to META-INF\com\google\android\updater-script and open it with notepad, and remove the first 2 lines, then save, and make the zip file (rename it to update.zip {careful not to make the file "update.zip.zip"}), then put the zip file in adb folder (for me its C:\\adb) and do adb push update.zip /sdcard/ (make sure adb is working) after it finishes pushing, go to bootloader (if not there already) and run temp recovery (twrp or cwm), and then install the zip, then clear dalvik and cache, and reboot, if first reboot doesnt work, reboot again, if it still doesnt work, install update.zip again. Hope i helped, if u have any questions tell me :3
=====
edit
=====
if you really cant get out of recovery theres still a way of fixing your tablet (same problem happend to me today and its fixed), if you already did all the steps above on the download .17 and extracting and changing the file of updater script then its already almost done, to access the bootloader you need to shutdown your tablet, press Power, Vol+ and Vol- at same time, it will go to fastboot, copy the file "droidboot.img" from the update.zip and place it in the adb folder (for me its c:\\adb), then do "fastboot boot droidboot.img" and it should download the img to the tab and boot to droidboot (you need to do this a few times, because 5/1 only 1 goes to bootloader), after booting to droidboot you can easily recover from there, on bootloader you have adb access, which means you can push the update.zip to the tablet (with update.zip in adb folder already, do on cmd, "adb push update.zip /sdcard/") after pushing go to temp recovery and install the update.zip normally after installing. format cache and dalvik, and reboot, if its stuck on logo, shutdown and reboot, if still doesnt work install the update once more by turning your device off and go to bootloader normally, (it works now, because it has the software now, (to enter bootloader press press power + vol-), and load temp recovery and reinstall). i hope i helped
I need some urgent advice. I was following this guide https://forum.xda-developers.com/le-2/how-to/guide-unlocking-rooting-restoring-to-t3515555 to backup stock recovery and boot. I did not want to flash twrp and su, so I skipped to wipe Dalvik/Cache, did that, and reboot from twrp.
Then the phone stuck in boot logo, I've waited at least 12min, nothing. So I tried to restart from stock recovery as stated in the guide, no good.
Basically I skipped step 16-20:
Download and install Minimal ADB and Fastboot: http://forum.xda-developers.com/show....php?t=2317790
Download latest official TWRP, place file in ADB installation folder, and rename to "twrp.img": https://twrp.me/devices/leecole2.html
Download SuperSU 2.78 (stable): https://download.chainfire.eu/1001/
Boot up phone and plug into computer
Settings > scroll to bottom to "About phone" > touch "Build" 7 times to enable developer options
Developer options > toggle "OEM unlocking" and "USB debugging" so that they're both enabled
When "Allow USB debugging?" window pops up on phone, check "Always allow..." box and hit OK
In Minimal ADB installation folder, hold Shift and right-click "Open command window here", then type:
Code:
adb reboot bootloader
Once in fastboot:
Code:
fastboot oem unlock-go
fastboot boot twrp.img
If password screen comes up, tap "Cancel" button
If it asks, tap "Keep Read Only" button (probably doesn't matter, but whatever)
Wipe > Format Data
Make backups (I suggest boot, recovery, and system since this will allow you to return everything to stock later on)
Mount > Enable MTP
Copy entire TWRP folder from internal storage to your computer
Copy SuperSU zip from your computer to root of internal storage
Reboot > Bootloader
Code:
fastboot oem unlock-go
fastboot flash recovery twrp.img
Hold Vol+ and Pwr until boots into TWRP
Swipe to Allow Modifications
Install > select SuperSU zip > swipe to flash
Wipe Cache/Dalvik
Reboot (first boot will take a little while, so be patient)

Hi, unfortunatelly I have the exactely same problem.
I boot to TRWP > wipe Format Data > did backup and restart.
Then my LeEco Le 2 X527 stuck on the booting LeEco logo. I've tried to Pwr+Vol Up and selected all the checkboxes to do stock factory reset but it didn't help.
Also, it seems I cannot use ADB, fastboot and TWRP any more, because after the Wipe the device is unauthorized
Did I brick the phone? Please help dear professionals!
Update:
I found that I can still boot to the bootloader by holding Pwr+Vol down. After that I was able to normally use "fastboot oem unlock-go" and
"fastboot flash recovery twrp.img" to flash the TWRP. After I installed the LineageOS and GAPPS and phone boot up successfully!

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.
Yow how do you enter Fastboot on the tablet and i haved tied avery button on the tablet and i dont see the fastboot option

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

so what exactly do i have to type at the command prompt to run twrp?,ive put the twrp img file in the same folder as the adb stuff.
3.) start command shell (cmd) in the fastboot instalation folder on your PC and check for the device connection with the command:
"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!!!
