Your other option prior to your first visit was to load LineageOS, but that would also have resulted in a wipe.

It would have given you time, however, to find a technician with more experience with this model.

On the other hand, the battery problem was physically dangerous, and that should have some bearing.

Yep I almost did that first but decided against it because I didn't want to get stuck with no phone in case something went wrong with the process. At that time I was technically on-call for work too.

The store owner told me they serviced a bunch of 4a devices and had lots of experience. They were also suggested by Google as an official repair center with good reviews.
