I have a Pixel 6a with GrapheneOS. Runs great for years, except for one or two apps that require an "official" Android.

Anyway, I now need to get the battery replaced, because apparently they are dangerous and Google pays for the replacement. Unfortunately, the replacement process requires the stock android to be installed. Meaning, I would need to backup the whole phone, reinstall stock android, then restore everything - and hope the whole ordeal works out.

That makes no sense. If there is a recall program for safety, surely they have to accept whatever software is on there? It's not relevant to the hardware repair
