Thread: Garmin eTREX 20 working as an eTREX 30

boot.bin is just an extremely small firmware. On most devices it even shares the same loading address with fw_all.bin.
But be careful with patching it, as boot.bin contains the bootloader and, sometimes, the x-loader and it flashes them on some conditions. If the bootloader or the x-loader crashes then the device is 'bricked' and can't be recovered without unsoldering the flash chip. So if boot.bin crashes while flashing the bootloader or the x-loader, it corrupts them and bricks the device. That's why we should be careful while patching boot.bin.
