I selected Android 12 and Lineage 19.1 as those have been out for awhile, and less likely to be buggy.
Should I go ahead and upgrade to Android 13 and try Lineage 20?
What does the error message mean?
The tablet says:
E:signature verification failed
E:error: 21
Install from ADB completed with status 2.
Installation aborted
Update: Apparently Error 21 means the bootloader is locked? I found these instructions to unlock the bootloader (which I think I've already done, it just didn't demand that I format anything).
- Connect the device to a Wi-Fi network.
Did this!
- Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
Did this too!
- From within the Developer options menu, enable OEM unloc.
- Power off the device, and boot it into download mode:
Did this too!
- With the device powered off, hold Volume Down + Volume Up and connect USB cable to PC.
- Now, click the button that the onscren instructions coorelate to “Continue” and/or “Unlock Bootloader”.
- Your device will reboot, you may now unplug the USB cable from your device.
My device did not reboot when I selected continue. It just took me to a new screen with the download stuff. My tablet did reboot after command "Heimdall print-pit"
- The device will demand you format userdata, please follow the onscreen instructions to do so.
My s6 lite did not demand I format anything. However, I later entered recovery mode and formated from there. Maybe this is where I went wrong?
- Run through Android Setup skipping everything you can, then connect the device to a Wi-Fi network.
Why do we need wi-fi enabled? We are flashing and sideloading through a USB cable?
- Re-enable Development settings by clicking the “Build Number” option 10 times, in the “Settings” app within the “About” menu, and verify that “OEM Unlock” is still enabled in the “Developer options” menu.
Mine never needed to be re-enabled. It remained unlocked.....
The instructions above differ from the instructions I previously used as found on the Lineage website:
