I have the very same issue - at least the error message is exactly the same - but for me I can:
use the phone just fine as my primary user
reproduce the crash 100% of the time by switching to any other user on the phone; after a few moments I get the error message “Factory data reset” and “restarting…”.
However:
I have an FP3
for me it started about 2 weeks ago and I haven’t done anything that I wouldn’t normally do when the crash happened the first time.
my SIM card is maybe 4 months old; I just removed it but the issue stayed the same.
I use an SD card for many months, formatted with exfat by the “add SD card” wizard; I just ran chkdsk /R (locate bad sectors) but all looks good.
Not sure how to do a backup that could be restored after a factory reset, but if all else fails, the factory reset will likely be my only option.
I added the bug report shortcut to the power button menu for the primary user; I’m guessing the secondary user can’t be a developer. And now what?
The only observation that may or may not be helpful is that the phone was really getting sluggish in the month(s) before, especially when using the second user. I got “system UI is not responding” every once in a while. Note that this was annoying, but not a problem. I assume it’s got to do with me using memory heavy apps.
FYI: FP have responded on the Factory Reset Loop post confirming that they’re treating this issue as a priority (assuming that the issue on that thread is the same cause as the one here; which seems likely).
I have followed the suggestion made in this conversation: Stock fp3+ factory reset loop - #125 by amoun and disabled my Google Play Services. After that I can change user without problems. However, on my primary user I do get a lot of errors because a lot of apps (phone, texts, etc) do not work correctly without Google Play services.
Hi pdw!
I will NEVER ever disable Google Play Services again.
I’ve a hardbricked galaxy s2 because of that…
(and also softbricked my FP2 but fortunately I was able to solve the problem in time)
I tested to disable Google Pay Services in primary user. I could switch to secondary user without problems. I checked Google Play Services, they are activated and all seems fine.
Switching back to primary user, activating GPS again, and switching to secondary shows the same error as before.
So, activated GPS in primary user profile does not harm this user but the secondary one. Seems strange to me
The solution for the bootloop issue without a sec. User is to deinstall Play services updates not to deactivate the app completely. Did anyone test this?
Deinstall recent Google Play Services updates
Go to Settings > Apps & Notifications > See all XX apps
Find Google Play Services
Tap the 3-vertical-dot button in the top right corner
As far as I understood the faulty update was already taken back by google, so the problem is fixed now for those who weren’t struck by the update and those who were able to deinstall it.
Have you deactivated updates within the play store? If yes my understanding is that this is no longer needed and I think there is a new GServices version out, which is not the one that was causing the issues…
