Yes, that OUT.rgn for user LAMedia, because I had also successfully converted to a Dezl 580, and after 1 month of normal use, Dezl start to restart and blinking...

What I did to convert my DriveSmart 50 (2267 Hwid):

1. First try with SD Flash GarminDrive 50 with HWID 2267:
[Only registered and activated users can see links. ]

System software missing happened after this, and I think here is a mistake

2. Then I use Flash x Dezl580 (via preeboot and updater):
[Only registered and activated users can see links. ]

Clear NV before and after, and was really successful convert, and normal functionality of one month, and couple days ago start to restarting, blinking...

Then I had try with your OUT.rgn successfully completed but same result, still blinking,
Then with CURE3 from drivesmart40-50 GUPDATE via preeboot, and then sometimes is recognized by GE and WebUpdater (I make one or two reinstall via WebUpdater)

Had try with RMPrepUSB but can't recognize

And then make with Cure3 original (without format)from DS40-50 via updater
After this I had try original Gupdate from Dezl 580 to make cure (changing 282601000400.rgn to a 226701000590.rgn) start only 40 %

Now had a situation that I see internal storage (probably strange preeboot mode around half a minute or minute sometimes), with no possibility to format and WebUpdater and GE can't recognize neither. Sometimes Garmin restart by itself and only logo is active

And still no luck and I think maybe it's broken, but I'll try some other things if you have more possibilities...
