[Moto G6 Plus Questions & Answers] Doughboy9:
Hi all,

after downloading and applying the latest update in LineageOS, the phone fails too boot (claims the system is unbootable). After a few attempts at booting slot a it reverts back to slot b, and boots the older version of LineageOS. Is there anything I can do to get updates working, without having to wipe all data?
