I repeat, DO NOT attempt to flash manually modified bootloader partitions to your Pixel! Including other "unknowns" like the DPM partition or the devinfo partition, which follow the same structure as the bootloader partitions!

These files not only have their own hashes that you need to watch out for, they are signed using Google's private keys which we cannot legally obtain!

Attempting to flash a manually modified bootloader WILL BRICK your phone. And as we just learned, attempting to flash a manually modified DPM will cause your phone to become unresponsive for a scary amount of time before EUB mode functions.
