I just bought a Pixel 7 pro, just for installing GrapheneOS.
After several failed attemps to install via WebUSB (cause I had no standard Android with plain Chrome browser, nor a Windows PC, and Chromium on Ubuntu does not support WebUSB), I finally succeded to install via the good old command line.
So far so good.
I verified that the install is ok with Auditor, that "successfully performed strong paired verification and identity confirmation".
on reboot, my device shows a red "You device is corrupt" warning and waits for confirmation before booting.
I don't think this is the intended result, as, as far as I understand, the main point of restricting GrapheneOS to Pixels is to allow verified boot with a custom ROM.
So... is this expected ? If not, what can be my problem and how should I proceed to correct this ?
Thanks in advance
