I'd have thought that the device sold in UK domestic market would run same fw and have the same HWID as the US market device. Try contacting the seller or Garmin UK to see if they can inform you regarding the origin of the device or better still give you the firmware.

Meanwhile, more info required:
  • So when you tried to dump the regions you used HWID 2842's ldr.bin in folder named 4044? That 2842 ramloader is from Nav VI Japan fw.
  • You didn't get successful dumps?
  • Also, why did you want to dump the bootloader rgn5? It's usually protected against writing/flashing in most devices anyway.
  • Do you have the full firmware for 2842 JN?


Please answer all 4 questions above.

When any flash is done the ramloader (bootbin/ldr.bin) is written to a virtual region 12 and rgn12 in turn writes the bootloader (aka Boot BLK) to physical region 5 and the X-Loader to region 43. It might be possible to convert the device to a JN device using HWID 2842's full firmware via Updater.exe seeing it's in preboot mode. Of course you'd need to understand that's risky and the device may die completely. However, it presently has 2842's bootloader in rgn5 and hasn't died, so maybe with JN fw_all.bin flashed to rgn14 it might boot up ... or die completely trying.
