I think it will matter what the GCD you do, the basic firmware is damaged from atypical FW. Will be essential to create the correct boot files... Thank you for your help
For 24xx / 25xx Asian (and the same hwid ie 2465 hwid1327 - TH-Sg/My-TWN)
Can FTL change the region ?
(Tested :: No effect if I flashed 2465TH with 2465Sg/My firmware.., Nuvi won't display Sg/My JCV.)
Hm, I don't understand what is damaged in the device and what is FTL. Also there are no 'boot files' at all. There are two regions in flash memory, one for fw and one for bootloader. I'm not sure whether x-loader is located in flash as I have controversial information. There is also the largest region in flash used to store internal filesystem. If internal filesystem is corrupted we can restore it either by flashing cure firmware and then formatting from Windows or by flashing correct filesystem header (Alexander's method).
That is what I meant - flash filesystem with filesystem header. (Alexander's method) Very cleaver way!!! 99% is fixing rebooting/freezing if the problem is coming from the memory - problematic files, corrupted FTL (I am calling the filesystem - FTL , bad formatting etc. Think it is much better than patching and playing with the main firmware. I see that you also know the method. That's nice.
Have a feeling everything is located in the memory - x-loader, bb, nvm etc in nuvi 265w. What other place can be located?
Don't know never seen an asian unit. But you can experiment.
Wow! We were talking about same things Personally I don't like flashing filesystem headers. It seems unreliable to me, unless you perfectly understand what those headers contain. Otherwise you have to flash entire filesystem, which will take too long time. Also you have to dump it first which will also take a while. As opposite, patching firmwares is something that I understand And it also helps, at least for old nuvis.
1)RAM is usually continuous on garmins (even after MMU configuration)
2)RAM addressess are quite different on 13xx.

About the x-loader...Sorry I really don't know.
aekhong, have you physical access to one SG\MAL 2465? May be, we can dump other regions and enable encrypted jcv on EU and TH devices? I need so Garmin Sync from SG/MAL and Thaiwan devices (I can't find this util in Web, but i know this util is preloaded on some SG and Taiwan devices).
