My FP4 is insisting on a factory reset, but crashes partway through it. I’m trying to get past that by reflashing it with the latest OS, but “fastboot flashing unlock” says it’s not allowed, presumably because I haven’t enabled it from Settings… which I can’t get into because of the bootloop.
(I think the whole thing may have been triggered by getting my first phone call or text after switching to an ESIM; it started soon after that, and also I get “com.android.phone” stopping, even within the bootloop.
I was using a Debian Linux system (similar to Ubuntu). I don’t think it’s a bug in the script; the phone is (correctly) refusing to let fastboot reflash it, because I haven’t enabled that through the “Settings” app on the phone. The problem is that I can’t get to the settings app, because the phone crashes while booting, at some stage earlier than making apps available.
I’ve now spoken to Fairphone’s helpdesk and they’ve arranged for me to ship it back for “repair” which I presume means some kind of reset that I can’t do myself.
