[SOLVED] Helppppp!!!!!

Some Time Ago I Posted A Thread About My W850i

My W850i has a white screen? Help? - Top Sony Forums

I Backed up The GDFS

I finally downloaded the firmware which was

W850_R1JC002_MAIN_GENERIC_CY_RED52
and
W850_R1JC002_FS_T_MOB_INT_A_RED52

Which Worked And My Phone Now Turns On But After I Select Normal Mode And Type In The Phone Lock Code It Comes Up With A Message Saying:

Configuration Error.
Please Contact Your Network Operator Or Service Centre.

Does This Have Anything To Do With Flashing My Phone?

Ive Contacted T-mobile and they said theyll get back to me

but i dont know what else to do?..

Look in my signature for that error

@maximus515: You've forgotten to upload custom pack.

As Seamonkey said, check out the 3rd link on his signature: -=CONFIGURATION ERROR - Answer is here=-
