I want to restore factory android on my Nexus 7 2012 WiFi.
I'm following the official guide.
I start the device in fastboot mode by executiong:
adb reboot bootloader
This works well.
But when I run any command that uses
fastboot the execution gets stuck, eg:
$ fastboot oem unlock < waiting for any device >
The same issue with
I also noticed that if I run
it doesn't list the tablet. However it gets listed if I run the same command after entering Recovery Mode (I have TWRP recovery).
More details/preconditions: I used to have CianogenMod on the device but I smashed it by mistake (I removed Android in recovery mode instead of simply wiping the data). I can't find the CianogenMod image anymore on LinageOS site (there is only Nexus 2013 available) so I'm trying to install at least what is available.
