Error after firmware upgrade on Z750, help...

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

Reinstall The Application. The Old Links To Database Are Now Invalid. Delete The App And Reinstall It.

I was thinking to delete the application too. But I cannot as SE locked it. I need XS++ to delete the application. However XS++ hasn't been compatible with DB3150 phone yet. Also, I don't know where to get the Google version which uses gps.
thnx anyway
