The repair rgn file supplied by Loly should be the same as the cure fw you made yourself by following the Cure3 tut. He posted that kit because sometimes ppl have errors making their own files but i was fairly sure that wasn't your problem.

You can try other things, here's one now: Let's first see if the unit can read from and write to the microSD. It would be helpful for you to have file and NV backups anyway so get a clean card, at least 2GB but preferably 4GB in size. Extract the rar file and then copy the Garmin folder onto the card, place it in the nuvi with it fully OFF and turn it on. Make sure you have it on charge because if this works it will take a while.
Spoiler: BackupRgn41&Files.rar

When its finished, look in the 0972 folder for a newly created file 'update.log' and check that shows the 2 commands for write to card as successful. If it is, you should have in the root of the card a full backup of your files in the Backup1 folder and a copy of your unit's region 41 as 41_backup.bin. If that's worked, let's then try to erase some suspect files from your nuvi.

If it doesn't work because ldr.bin is loading too late, we can try kunix's method to execute a patched version from updater.exe. Over to you ....
