But this is quite complicated and I won't have time during the next two weeks.
Please help, I am willing to try anything.

So I tried to updater.exe region 16 and 41, it won't let me as you said. Whats region 15, you know?

However, region 48 seems to flash. I took 48.bin, with Ultraedit removed most of possibles and saved it. Then took 50mb of this file and made 48.rgn. Updater.exe accepts, Erasing... maybe like 5 mins then it writes 48.rgn successfully. No change with Garmin, still bootloops. Next, flashed 10mb of pure FF's to region 48. No change with Garmin.
