No, CHN2.50 make 3790US reboot.
I tried with
1).original US boot 2.50 and 3.60 + CHN220resources.bin + CHN220fw_all.bin(override to 1101) --> Rebooting loop
2). Original CHN250 .gcd --> system software missing
3).Modified CHN250 .gcd --> system software missing even CHN2.50 boot.bin contain 3 hwid-swv( EF 04 FA 00 ) as US boot.bin

@aekhong, so how will I be able to use my Philippines.JCV? Which firmware do I need?

Maybe you need fw update for 37xx Philippines. (Do we have 37xx Philippines ? <-- I don't know this info.)

As far as I know, there is no 37xx Philippines firmware. All the 3790T here are 3790US. The only Philippines-specific Garmin available here is the 1360. Do you think that JCV is only for the 1360?

Hi kevindd992002
Something like that.
For example ., Thai JCV is for firmware of 1460TH / 1360TH/1250TH/3770TH/2575TH not for 24xxUS
You need the same series as sell in Phillipines(Then you can get Phillipines fw to modify) (and a good luck for converting your unit.)

Ahh. Where can I get the specific firmware that is compatible with the PH JCV? Also, how do I know if the JCV is locked, will it show a gray square box just like what it is doing in my 3790US?

(JCV) Thai / SgMy / Indonesia / Phillipines ==> all are locked.

So an SgMy firmware can't use a CHN JCV?

Is it possible to convert 3790T US to TH to use Thai JCV?
