I tried wiping my old Lenovo tablet using the following methods but none work
Factory reset through the phone
Erase all data using Google's Find my Phone
'wipe data/factory reset' -> 'Yes -- delete all user data' reset using the bootloader
So I installed ADB through android-tools on my latest Manjaro Cinnamon as well as android-udev and tried the following but they don't work either.
$ recovery --wipe_data
/system/bin/sh: recovery: not found
127|shell@android:/ $
$ wipe data
Wiping /data
Error opendir'ing /data 'Permission denied'
Done wiping /data
shell@android:/ $
$ adb shell am broadcast -a android.intent.action.MASTER_CLEAR
Broadcasting: Intent { act=android.intent.action.MASTER_CLEAR }
Broadcast completed: result=0
The device won't load as fastboot nor is there an option to fastboot under recovery or developer tools. So 'adb reboot bootloader' or 'fastboot' devices does nothing either. No root access option in developer tools either. So:
$ su
/system/bin/sh: su: not found
127|shell@android:/ $
and
$ adb root
adbd cannot run as root in production builds
$ rm -rf /data/*
rm failed for -rf, No such file or directory
So I don't know how to proceed and feel like I am out of options. Can someone help me please?
mountand to flash userdata partition. Thank you. Will revert back soon – Corinthea Dec 31 '20 at 13:34mountbecauseadb rootwon't work prior to it. And flashing the partition won't work because the tablet does not have a fastboot mode – Corinthea Dec 31 '20 at 13:57
