I’ve got a second-hand Pixel 1 last week, I unlocked, installed TWRP and rooted yesterday, but I unrooted today because some reasons.
I did a wrong decision, I erased the phone by System Settings, and locked it.
After I locked it, when I boot it, it only have Google logo flash for about 0.1second then gone. I tried to flash the factory images from Google, but it requires unlock to flash it.
I even can’t unlock it now because I can’t get into the System to turn on “Allow unlock OEM loader”, so it got failed. I used fastboot OEM unlock and fast flashing unlock, they both doesn’t work.
I don’t really want to send the phone back to Google US because I doesn’t live in America, so it’s not really easy and really expensive to send it, and I also really need this phone because the battery of my old phone is almost dead. And the Google Support Team in my country/region says that I can’t send to the repair center locally because they only accept Pixel 3/3XL/3a/3aXL/4/4XL
Thanks the suggestions from you guys!
