I tried to upgrade to SGMY v2.50 but unsuccesful. I've tried using the boot.bin from both US v2.50 and v3.60. After load the modified firmware, the device just keep rebooting. I have to reload the mod SG v.2.30 in order to bring him back to life.
I've success upgrade my Nuvi 3790T US version to SGMY v.2.30, but everytime I go to tools> settings> display, the unit immediately turn off. What have I missing?
Tried with 4.10US + 2.50CHS by editing hwid = 1101, keep rebooting.
PCB version = 8
Is me again. Today, I tried to upgrade my 3790t (initial is US version) SG/MY v2.30 to SG/MY v2.50 but failed. It stop after "Garmin" logo.
1) I make a mistake without H/R before flash with rgn
2) I forget to disable all of Text., Keyboards ., Voices ., before flashing
3) I'm using previous US boot.bin (HWID1101 ) that I used to convert US to SG/MY v2.30 (will this caused an issue too ?)
Then I flash with cure.rgn that you provide during I convert US to SG/MY. After flash, it can continue after "Garmin" logo and shown "load maps" , after "load maps" immediate it turn to another error screen below and only allow to exit and turn off device itself.
