AT&T Pixel Pro bootloader has finally been unlocked
XDA Senior Member sirhc has finally shared how he managed to unlock the bootloader in his AT&T Pixel 7 Pro. While it involves a few strings attached, it is still worthy of your attention. Initially, the XDA developer had a carrier-unlocked AT&T Pixel 6 Pro with a SIM card inserted. He then chose to switch over to an eSIM on another device (A). While the physical SIM was still in his Pixel 6 Pro (registered to AT&T), the phone number got transferred to his device A. To test it, he pulled out the physical SIM from his Google Pixel 6 Pro and insert it into the Google Pixel 7 Pro and factory reset the phone. Once the device booted up after the reset, he found out that the OEM Unlock Toggle wasn’t greyed out. He then enabled this toggle, booted his smartphone to Fastboot, and executed the Fastboot flashing unlock command. And the bootloader on his AT&T Google Pixel 7 Pro was unlocked.

Whether this was a bug from Google’s end or the carrier isn’t ascertained yet. If this was indeed a server-side bug, then there is no concrete evidence that it has been patched yet. Now is your perfect window of opportunity to have a shot at unlocking your Pixel 7 Pro. Before you do so, you should remember that it could nullify the warranty and reset your smartphone, so have a backup beforehand. Source
