I have seen through a web search that there were older discussions abut this, that is how I got here. NIB, unlocked Pixel7a from amazon. Fully, freshly, updated to the gills. Tried to install Graphene Lynx. Went well up to restart and locking bootloader, then went into boot loop with a trouble code : g.co/ABH. What I have been able to identify is that usb connectivity has been lost specifically with the pixel. I have tried three different cables, including the cable that came with the device, and two different ports. All three cables, and both ports work with other devices, I tested them through the course of troubleshooting and the pixel remains in the bootloop whether it is connected to the laptop or not. So somewhere in the process, after flashing the device, and upon restarting, USB connectivity at the device is being lost. There is another code, ID: 003f1ade I have 32gb of ram and over 1 tb of free drive. Thanks in advance
