1.2 Save the second bin file fw1_resources (the question is, is it the third option in RGN_tool resources.bin?)
2. The option I can save the files is RGN or GCD, I believe we are ONLY interested in RGN.
3. You mentioned loading each saved files separately to RGN_tool (I believe by dragging them one by one to the "File Drag Zone" and save as 113201000390.rgn.

Thank you for the file, as you can foresee this task is beyond my capability. Appreciate.
Yes it seems that final sentence is so, because your interpretation above it is completely wrong but don't concern yourself any further about it. Just use the extracted file from the rar i've attached there in the first part of my Post#27 and drag the extracted 113201000390.rgn onto updater.exe, put your unit in preboot and flash it.

I tried the GarminCure3 method by kunix with other device and was successful resurrect the device. load cure, update.exe and pre-boot, reformat with RMPrepUSB and load with original in pre-boot.
Sure, i know that. But now you don't have MSM and you can't load anything in preboot seemingly, so something is preventing that. My point was [and remains] that you already had MSM before using cure fw because you were able to delete the existing gupdate.gcd as requested by the support lady at Garmin, right? So imo there was no need at that time to load cure fw because you already had MSM. But you've since lost Mass Storage Mode. My reading of your posts indicates that since you 'cured' it, you've been unable to [successfully] load original fw and are still faced with 'system software missing' message, correct?

I think they are the 113201000390.rar and Garmin.rar (Post #16) I got from you. I shall put the Garmin rar (gupdate.gcd and update.txt) in a microSD and insert it in the device. And the 113201000390.rgn in the 113201000390.rar post #27 is to be dragged over the updater.exe and pre-boot my device to flash it.
Don't put Garmin.rar in a microSD, extract it onto the card so that Garmin folder and gupdate.gcd are in the root of the card, then the rest above is correct.
