Ok, so here's what I did. I was hungry and annoyed about a previous project (buying Google Play gift card with cryptos to pay for ChatGPT with fake google account, Google needed to "verify" my purchase of the gift cards...). Anyway, I had installed ChatGPT in my main User Profile, but under the work profile in that User Profile which I created with Shelter. I was holding my baby and talking to my wife while mindlessly going through Shelter and setting all the apps to autofreeze when I hit the widget on the home screen (because I hate invasive apps like everyone else here). Well, then I had the bright idea to make it show all the system apps in the work profile and then set those to freeze as well. I did most of them, and then I tested it. My phone froze. The display now blinks my wallpaper for half a second then goes black for two seconds and does this over and over.
Here's what I have done to try and remedy it:
I've tried getting in with ADB. I cannot get into the phone. I do not think I have USB debugging enabled.
I have tried Safe Mode, it still just blinks even though I can see Safe Mode at the bottom when it blinks.
I have flashed the latest OTA update to try and reset some of the system settings. The update was successful but after reboot, it still just blinks the screen. No change.
I haven't made a backup recently, so I'm really hoping I can find a solution. Obviously I still know my PIN, and the phone itself is in good shape (Pixel 8 Pro). Any comments saying I'm an idiot are welcome as long as you also pair it with a potential solution besides factory reset. Thank you for any and all help. I love GrapheneOS, even if the security is so airtight I can't get into my phone when I do something dumb.
