Since the OS image had zyxdl modified, I first needed to figure out the checksum zyxel p-320w the firmware update file. And zyxel p-320w, I re-soldered the chip afterwards. See my previous posts for more details on the programmer that I used to read and write to the flash chip. First, I could simply set a breakpoint on this conditional branch zyxel p-320w change the zyxel p-320w contents so that the recovery image is never loaded.

The checksum field itself is set to 0xFFFFFFFF at the time of calculation, and the checksum is calculated over the entire firmware update file, except for the board ID string at the very end.
