Just to update you, that notification you can see , good news, your tool detects version on this nuvi 765 now like a 4.50 version, even i think there wasn't good flashing, cause it finished too fast, 15-20 seconds, but at all there is now written info 4.50 firmware installed, cause you toool says "same version is installed, do you want to run same version for flashing" bla bla, so i confirmed, that i want to rerun 4.50 - original, not your patched, but then again stupid message about requested memory ...

At all, now no "loader loading" message , 1 step of progress , it stays on Garmin Splashing screen, and after 2-3 minutes again message "system software missing", probably cause firmware wasn't flashed ok. We need to discover, with your patched 4.50 to flash it full .

p.s.
I create you FW 4.50 with pk_files66 inside.
Try flash in pre boot.

i'll try your modified firmware right now, you'll have info in 2-3 minutes, how much usually takes flashing ...

I told will be fast :

1. At all, 1st time that 4.50 suceed to flash , in this state, so it seems really there is something with pk_files66 and accepting newer firmwares 3.90 to 4.50 on nuvi 765 !

So this is progress, now came some idea to me , that maybe kunix trys this, to use this your 4.50 firmware with pk_files66 inside, and to modify it, like 1st 4.50 modified, and then i can try it, cause with your firmware with pk_files66, again message "loader loading" after finished flashing, but with kunix 4.50 patched version this message didn't appear after flashing, by GarminCure3 !
