I can almost certainly say the conversion to 465T is coincidental and the problem is purely due to something which has occurred when you updated to 2026.20 map version. The transfer was either incomplete, or the file got corrupted.

Hi everyone,
I'm trying to build a manual Cure for a Fenix 6X Pro stuck in a boot loop. The official firmware (GUPDATE.GCD) I have doesn't contain the boot.bin, so Cure3 can't process it.
Could anyone share a full .RGN or boot.bin (section 0800) compatible with that model (same HWID)? I can also download it via Dropbox or another secure link. Thanks in advance!

The GCD contains only a bootloader (section 0505 - region 5) rather than a ramloader aka boot.bin (section 0800; region 12 [hex 0C]). Usually the ramloader is flashed to region 12 which is a virtual region and then the bootloader component in it is then flashed internally from 12 to region 5 along with the X-loader to region 43. The watches are set up quite differently and i'm unsure of how the firmware is handled by the device because in most Garmin devices region 5 is protected from direct flashing.
You can certainly convert the fenix's GCD to an RGN using RGN_Tool however either as a GCD or RNG the file cannot be processed by Cure3 because it doesn't contain a boot.bin.
You could try using QuickCure3. It's a modified 'universal' ramloader of sorts. Many devices are compatible with it, but some are not unfortunately. It may work or at worst it might hard-brick the watch.'Thanking Posts' are banned.
