@demise7625 I thought I bricked my pixel 2 xl until yesterday. I tried installing android 8 from flash.android.com since I read somewhere that it might help but it failed while flashing and the device was stuck on fastboot screen. I tried flashing android 9,10,11 after that but it kept failing. I gave up thinking I bricked the device. However, yesterday I managed to flash android 9 manually using a different computer (older). The only thing I did differently is I ran fastboot flashing unlock_critical
this time. So either that helped or there was some problem with the computer.
After that I simply followed ubports installer instructions and everything worked seamlessly. So I would suggest try these, it might help:
- Try
fastboot flashing unlock_critical
-> flash android 9 -> run ubports installer - Try a different computer and use a usb-a to usb-c cable.
I also remember reading that someone managed to get it work by using a usb dock insead of directly plugging into the laptop's usb port.
Sorry for the long answer, just logging my case hoping it might help someone in the futurej
