Thread: 3790 in endless boot loop

Only Thai OS can use Thai JCV.
I'm sorry to say no way to modify other 37xx region to use Thai firmware (till now).

Your choice is
1). Sg/My 2.30 (No calendar., No contact)
2). CHN 2.20 (get Calendar & Contact but have no co-ordinate feature)

Taiwan 2.30 has many bugs., Thai 2.10 also.

I use 3790US with Sg/My 2.30
No Thai jcv .

Sg/My give us option to display half or full screen JCV as below.



And we will get the real time Lane Assist on the full screen JCV displaying.
