The worst? they can do is erase the FLASH & EEPROM leaving you to sort out reloading it all to get it working again.
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.
