@jrgood78 I have had this on other devices after an INCELL screen replacement, more recently a OP 6T. The screen works in Android but not on UT. You could try going back to Android, making sure everything works, then reinstalling UT and see if the screen is picked up.

BTW, INCELL is a type of screen that is cheaper and more hard wearing than more expensive OLED screens. They are not as vibrant colour wise than OLED screens and if the fingerprint reader is under the screen, that usually won't work with n INCELL screen replacement.

@KJU Just to point out, Ubuntu Touch is the name of the mobile operating system that you have installed and given good account.

UBPorts is the charitable foundation that helps develop and finance Ubuntu Touch through donations and sponsorship.

@ResuWen Check the end of this thread on XDA-Developers forum. There is a media fire link that works.

@E-Z-Tux You don't need to power up the device. You log in to the software fix tool with a Lenovo account or a Google account. Select Tablets. Select use the serial number to recover. Enter the serial number of the device. Download the ROM. Ensure the tablet is powered off. Follow the onscreen instructions to recover the device, which involves holding volume up and volume down and plugging in the USB cable plugged into the PC when told to do so. Then leave the device alone till it reboots.

@E-Z-Tux You don't need to have USB debugging enabled. If you have the serial number of the device (sticker on back of tablet or on box) you can recover to Android.

@MadDino it elevates the command. I have had to use it installing UT on other devices.

@MadDino Put the unzipped folder on your desktop. Attach the phone to the PC in fastboot mode. Open a terminal in the unlock folder. Run the command ./unlock.cmd. Note the ./ in front of the command.

@E-Z-Tux All is not lost. You need to charge the device up. Put it on charge for a day. If it fails to boot after that then you can use the Lenovo Software Fix Tool to recover Android to the device (requires a Windows PC).

@MadDino I have used Windows 11 to unlock the bootloader and install UT my ASUS devices. It is not the easiest phone to install UT onto. The build number won't make a difference unlocking the bootloader, but when you unlock the bootloader use this (quote from devices page):

"The port is based on Android 9 firmware (WW-16.2017.2004.063) and Lineage 16 vendor image. Current Recovery will be replaced with Ubports Recovery!"

I think you are experiencing difficulties with the ASUS drivers. On Windows uninstall the drivers, reboot the PC, install the drivers and try again. If that fails try disabling driver signing which is a bit of a messy workaround. I found that one of the Windows updates messed with the drivers and uninstalling them and reinstalling solved it.

@MadDino The build number should not make a difference. Try running it in an administrative command prompt and run the command with ./ In front.

@MadDino Start the device up and the bootloader should be unlocked.

@Balrong Uninstalling core apps is not advised as there is an issue reinstalling them. I would run the device through the installer again and leave the wipe data box unticked to resolve.

@MadDino Check here. Download the unlock.rar file (link still works). You don't need to root the device for UT. Follow these instructions and you need a Windows PC:

*DATA WILL BE WIPED SO MAKE A BACKUP

1. Download this zip(you already have) and you'll get 2 folders 'unlock' and drivers
   https://drive.google.com/open?id=1YpezCedaRWGDS9WW7UaXXyyBod0Bk5qp
2. Install the drivers and go the 'unlock' folder
3. Reboot your phone to fastboot mode by pressing volume up + power on at the same time.
4. Connect it to pc and open unlock.bat in 'unlock' folder
5. Done*

@rocket2nfinity fastboot reboot fastboot will put you to fastbootd and you cannot unlock the bootloader from there.

@hlbkv said:

but on connection it gets back to the generic gear icon.

That's normal restarting the Network Manager.

You can reinstall through the installer leaving the "wipe data" unticked which will retain all your data and take about 10 minutes or in updates change the channel to development and then back again.

@shengchieh It usually means the "OEM unlock" toggle in Developer options has not been set to enable. Other scenarios include old versions of ADB and fastboot on the PC, if in the US, no token .

@hlbkv Have you tried a reinstall?

@hlbkv Is it the TB-X306F or X? I haven't experienced this on Focal or Noble and I am running on Stable. I have seen this on other devices running development and it usually happens after sleep. Have you tried resetting it using network manager?

sudo systemctl restart NetworkManager

What is the device?

@shengchieh are you in the USA? The US devices seem to behave issues unlocking the bootloader. If not, have you enabled developer mode and enabled OEM unlocking there? Edit: I see you have, but double check. If you have downgraded the Android version it automatically relies the bootloader.
