Updating FNIRSI IPS3608 Firmware on macOS
FNIRSI’s IPS3608 firmware updater assumes Windows. Here’s the macOS workaround: the bootloader exposes a FAT12 disk with unusual 2048-byte sectors, so a normal Finder copy silently fails. This walks through reading the raw image, patching it with mtools, and writing back only the changed sectors — plus a Python script that automates and verifies the whole thing.
