This happened to me. My phone was acting strange so I restarted it. After unlocking, it said 'Phone is Starting' for longer than usual. Then it said 'Factory Resetting', and shut down.
It opened up a weird bootloader-like screen asking me whether to factory reset, or try again. I selected try again, which took the phone into a 'Phone is Starting' loop that never ended.
I ended up going to https://pixelrepair.withgoogle.com/ and factory resetting from there.
This is what you should probably do to avoid this happening to you. (Everything I know about this is from what happened to me, and the article I linked, so idk if this will actually help)
- If you're not using multiple users, do NOT enable it and make sure it's disabled.
- If you are using multiple users, consider disabling it.
Also, BACK UP YOUR PHONE
Google makes it difficult to create backups, but it's really important. Even if you're very lazy, doing one at least every few months is worth it. You never know when your phone will fall into a lake, or delete itself because Google doesn't know how to make phones
- If it's not already enabled, turn on Google's automatic backup, at the very least for apps.
- Make sure your password manager / 2fa apps are backed up.
- Make sure your photos are backed up. Google photos is the only option by Google to back them up, so if you don't want to use that, you copy them to your PC or any other external storage.
- Some apps, like Signal, WhatsApp, or Aegis aren't backed up by Android's normal app backups, so you might have to turn on backup app by app.
- For some apps (like Signal), backups are just saved to a folder on your phone so make sure you move them to external storage.
- I don't think files on Android are backed up at all, so copy any important files to external storage.
- If you have contacts saved on device (not linked to a Google account), copy them too.
Also, please tell anyone you know that has a Pixel about this.
Rant
This situation has been handled horribly by Google. This is a serious bug; wiping your entire phone isn't something that can be shrugged off as a minor issue. Even in the best case scenario where someone has a full backup and loses nothing, you can lose access to your phone for hours or days.
There are articles about this bug going back to the 17th. Google could've put out warnings, Stopped rolling out Android 14, Added a warning when enabling multiple users, or Mentioned they're working on fixing it.
What have they done? Nothing. According to the article, they haven't even acknowledged it in the bug tracker. If they even just warned people, I probably wouldn't have lost anything.
I didn't have any backups for photos (I know, my fault), but luckily I send most of the important ones to my girlfriend or family so I hope I'll be able to get them back soon.
Also just want to mention how bad backups on Pixels are. The fact that there is no way to back up your phone onto a PC or something and you can only do it with a Google account is ridiculous. Backups don't work for some apps for seemingly no reason. Why are photos only able to be backed up with Google Photos, and not as part of the normal backup? Why is there no backup at all for files?
I won't be buying a Google product ever again.
The article I linked mentions work profiles, but I'm gonna be honest, I have no idea what a work profile is, or how it's related to Multiple users, so I can't say anything about that.
