Issues after updating from 6.2 to 6.3 on Google Pixel 6a (bluejay)

A couple of weeks ago I installed iodéOS on my device, but I recently received the update to version 6.3 and since then, after rebooting the operating system to fastboot, it no longer works. The device has the bootloader locked and now it won’t let me boot into fastboot mode.

Now, both my Windows and Linux computers only recognize the device when I plug in the cable and press the power button, and it shows up as “Pixel Recovery ROM”.

I’ve tried with different cables and three different computers — I even formatted one of them just for this purpose, testing with Windows 10, Windows 11, and Linux Mint.

Key combinations to boot into bootloader, recovery, and other modes have no effect, and the device is never recognized as fastboot or adb. Did I just lose my smartphone? Has anyone else had the same issue? Thanks!
