Yes, the restarts are because if system-ui restarts 3 times in a row the system is rebooted. There are two ways to fix it, the first is the recovery initrd, which will trigger the warranty void warning and open mode. The second is trying to uninstall it quick (over SSH or otherwise), try plugging in a USB cable into a PC and booting up. I'm not sure if R&D mode would help, never tried it on Harmattan Code: flasher --enable-rd-mode --set-rd-flags=no-lifeguard-reset
flasher --enable-rd-mode --set-rd-flags=no-lifeguard-reset
