Hello.
I have been putting custom roms on android forever , but this was my first time trying GSI and of course the first time when I`m stuck! TWRP is working, but I can't flash a rom, GSI didn`t work out and none of "stock rom" works either.
I`m just hoping maybe someone has some image of what I can try to flash or have been in a similar situation and know how to get out of it.
Any other ideas are welcome too.
Thanks.

If you don't have a backup, you can rescue your tablet using Lenovo's LMSA tool.

This version of TWRP works on the Lenovo TB-X505F (wifi).

For the TB-X505X, see this thread. For the TB-X605F/L, see this thread.

For the TB-X606F/L, see this thread. The X606F/L is the second gen M10 and it uses a Mediatek SOC.

Working:
AFAIK, everything is working including:

• data decryption
• MTP

Known issues:

• time not adjusting for Daylight Saving
• OTA (for a workaround see this post)

Installation
It is recommended that you also install Magisk. This will ensure TWRP remains your default recovery.

Step-by-step guide

1. download TWRP to your PC (see the Download section below)
2. download magisk.apk to your MicroSD or OTG device. Get the latest Magisk apk file here. Rename the filetype from apk to zip (for example Magisk-v22.0.zip)
3. if your bootloader is already unlocked, go to step 4. To unlock bootloader:
   • on tablet: go to Settings->System->About and press "Build number" 7 times to enable Developer Options.
   • on tablet: go to Settings->System->DeveloperOptions. Turn on: "OEM unlocking" and "USB debugging".
   • connect tablet to your computer. Tablet will ask for permission to "Allow USB debugging". Tick "always allow" and select "OK".
   • backup any files you want to keep to an external device (MicroSD/OTG/computer), because the next step will wipe all your photos, files, google account etc on the tablet.
   • Now unlock the bootloader:
     

     adb reboot bootloader
     fastboot oem unlock-go
     fastboot reboot

4. flash the twrp image:
   

   adb reboot bootloader
   fastboot flash recovery twrp.img

5. if you haven't loaded Magisk yet, go to step 6. If you have already loaded Magisk, you can just reboot and you're finished:
   

   fastboot reboot
   adb reboot recovery

6. load Magisk (step one): reboot to recovery. Do not reboot into the system, because it will over-write TWRP with stock recovery. If that happens, go back to step 4 and start again. When you issue the reboot command (below), you have to immediately press the button combination to reboot to recovery (TWRP). Here are the steps:
   • issue the reboot command:
     

     fastboot reboot

   • immediately press and hold all three buttons (Pwr+VolUp+VolDown). The tablet might reboot twice. Release all the buttons when you see the TWRP screen, or hear your PC acknowledge that ADB is connected.
7. load Magisk (step two): flash Magisk. In TWRP:
   • select "Install"
   • use "select storage" to locate device you stored magisk.zip on.
   • press the OK button
   • select the Magisk zip file
   • swipe to confirm Flash
   • when Magisk is finished, hit the "Reboot System" button
8. finished!

If you prefer to use button combos, rather than fastboot/ADB commands:

• Vol Down + Power = fastboot mode
• Vol Up + Vol Down + Power = recovery mode

hi, thanks.
i did like the guide says
i 'v got an error
failed to mount /sdcard no such file or diretrory SDCARD_ROOT not mounted
any idea?
any gsi rom for the x505f?
thank you

 

[Yahoo Mike]

i 'v got an error
failed to mount /sdcard no such file or diretrory SDCARD_ROOT not mounted
any idea?

Might be the format of the sdcard. How is it formatted? Try reformatting with a different format type. Either NTFS or exFAT should work.

Also re-seat the sdcard. It might be misaligned.

Or try another sdcard - maybe the card is faulty.

I just posted the v3.5.1 update to twrp.

It's also changed to landscape mode, as many of you requested.

Thank you at all for work.

Unfortunately, this TWRP 3.5.1-0 doesn't work anymore on latest stock update TB-X505F_S001142_210804 and some below versions too (flash tried before and after update).

After fastboot oem unlock-go successfuly, I followed all @beamingbadger steps and all is okay to this stage:
Sending 'recovery' (31830 KB) OKAY [1.016s]
Writing 'recovery' OKAY [0.355s]

But fail: auto reboot on system after fastboot reboot recovery. And via holding all 3 buttons and release on Lenovo splash screen, I get the stock recovery
No way to solves this issue.

Update is planned?

Thanks for help.

It works. I just re-tested it.

fastboot reboot recovery has never worked on these devices.

Make sure you are not rebooting into Android after you flash twrp. Unrooted Android will re-install stock recovery (and delete twrp). If you accidently reboot to Android before installing Magisk, then you'll have to reflash twrp and try again.

I know the 3-button reboot is tricky. But keep trying and you'll get the hang of it.

Update is planned?

It's probably time for an update - especially with A12 GSIs coming out. I'll have a look this weekend.

 

[Yahoo Mike]

There's a new image on the OP: twrp-X505F_11.img. It is version 3.6.0.

This image should be compatible with Android 12. I haven't tested it on A12, only on stock ROM (A10). Let me know if there are any issues.

Okay, I will try again (and again) with hardware buttons only.
I had no idea that fastboot reboot recovery doesn't work on these devices, specially when it has always worked on all the others (many times, including another tablet model of the same brand). Thanks for the warning; I could have spent many time to trying this again for nothing!

Thank you!
> And thanks again for update!

Hi all im trying install TWRP but something is wrong...
I download platform-tools for adb ...

After i type adb reboot bootloader my lenovo reboot to fastboot and after that i type fastboot flash recovery twrp.img and i get < waiting for any device > ???

"
C:\adb>adb reboot bootloader
* daemon not running; starting now at tcp:5037
* daemon started successfully

C:\adb>fastboot flash recovery twrp.img
< waiting for any device >

"
*** All good now i install the usb drivers on device manager (windows 10) and all working perfect. ***

Thanks for the great work.

Yall running android 12? how and how does it run? id be fine with android 10, but lenovo thought to replace the multitasker and it only works right if you use the stock launcher. i have to have a gesture to get it working with nova.

 

[Einheit-101]

The tablet booted fine exactly once with Magisk and TWRP and after that it refuses to boot anymore and instead directly boots into fastboot. My guess is Magisk ****ing things up again, as usual.

Lenovo Rescue Assistant recovered the device, i will now try again and reboot multiple times to see what exactly crashed the tablet.

Hey All,

So i've just got one of these tablets and have spent a couple of days trying to root it now, is there any updates or new threads/solutions out there for this yet please?

hi,
i had the same problem, fixed by flashing also the boot not only the recovery.
fastboot flash boot twrp.img
fastboot flash recovery twrp.img
work for me
p.s
be sure that you flash the correct system.img (i used Havoc-OS-v2.5-20190527-vvBuild-phhgsi_arm64_ab.img - work perfect)

 

[ae01]

the solution with the lmsa worked!
the lmsa unbricked my device, then i flashed the twrp , flashed the magisk , and then the tablet booted rooted.
thanks a lot yahoo mike.

An important step to unlock bootloader is to update to Pie, otherwise I get

> fastboot oem unlock-go
FAILED (remote: 'unknown command')
fastboot: error: Command failed

NOTE THAT THIS GUIDE IS ONLY APPLICABLE IF YOUR DEVICE IS RUNNING ANDROID 9.0 (PIE). If your device shipped with Android 8.0 (Oreo), you must upgrade because the Oreo bootloader does not allow a permanent unlock.

@Yahoo Mike can you update the first post?
