Yeah, MKII splash screen is pretty easy to change with my ICC Comms program already, using the recore button & USB script to replace the default image. And yes, my units all have WiFi root terminal access with Y-MODEM file upload and download - so I've got a few options.

What you are after though is a CAN recording of firmware 8R29-14D017-AC being loaded into a MK1 low-series FDIM by IDS... That's what I meant about re-inventing the wheel (since you need to upload the entire firmware, I would only be re-inventing the IDS firmware upload process - also, I don't think Forscan can do this, .PHF files are a bit different to the .VBS files Forscan handles).

The actual process to unpack, edit, and repack with new CRCs a MK1 firmware for changing the ICC splash screen is not very hard. But you really want to choose your image carefully, it's a big process to go through on a whim.
Ill be using the most ridiculous image I can find, likely a pic of pixelized boobs. Could one point me towards software that could unpack? Would this be converting .phf to a binary file, and then unpacking the binary to a 'readable' format, changing the image out and then repacking and recalculating checksums, converting to phf and reflashing the unit via can diagnostics.
