I then wanted to flash gapps, so I enabled recovery reboot in the developer options in the settings, I pressed the power button and I chose to reboot into recovery.
The phone just reboots normally.
Please note that root access has not been destroyed, I can access files that require root, it is just that the recovery reboot does not work, and now I am stuck with a ROM that I just wanted for testing purposes. Didn't expect that it would lock me in
Any help appreciated.
