7dutch My phone is a Pixel 6a. The phone is still without files.
The screen now keeps moving on logo so does not stand still. Restarted multiple times and i can go to
the bootloader,rescue mode etc.
Honestly the Matrix channel will likely provide the most-expert advice, as @treequell suggested, and they might be able to not just get you going again but also collect data about what happened.
That said, if the phone has no data you care about, personally I would try "factory reset" before sideloading an OTA image, if only because it's easier and faster. But that will work only if the problem is in the user-data filesystem; if the problem is in the system side then I believe only an OTA image or wiping the device entirely would work. For me the recovery mode menu includes "Wipe data/factory reset", so if you can get into recovery mode and really don't mind wiping your data you could try it.
