Error after firmware upgrade on Z750, help...

[siung777]

Hi guys,

I get a problem with my At&t Z750,
first of all, I debrand this phone w/ Davinci Team with Z750a R1EA038 CID52 and everything works fine, I tried the gps and google maps.

The next day, I saw there's a new firmware R1FA030 CID52, so I updated my phone with SE Update service. I update from asia region as my version is APAC.

The problem is that after I update, I tried to use google maps, but I can't. It shows an error screen:

Error:
darken_image
Exception:
class
java.lang.RuntimeException
Init Stage: 5

Does anyone know about this problem?
I would really appreciate for the help.
Thanks
