constantine99 Hello I have a pixel 6a with Grapheneos 6 months ago and when I connected my device to the car for charging. When the device turn on was reseted and I lost all my data
That's terrible! Can you say a bit more about what happened? How low was the battery when you plugged it in to the car? What sort of car charger was used? Was the engine started before or after the phone was plugged in to the car? Do you recall what was displayed before/during the reset? Did you get any red-text warning about the device state being corrupt, or did it just power on blank?
constantine99 I dont have a backup anyone know how can I restore my phone?
Unfortunately, based on the description so far it might be the case that the former contents of the phone are permanently gone.
