W595 question please help me

Hi!

First, i have t-mobile branded w595 phone, with disabled flash.

I have read one solution to enable the flash feature.

I have used A2uploader to change my CDA number. After this i can update with SEUS (SEUS read this CDA number) my phone with another software with flash support. But, i need no more this flash feature and i need my warranty back.

I have restored my original CDA number, and with the SEUS my branded t-mobile software.

I have lose my warranty or if i restore my CDA and my factory software, i have no warranty problem? Some people say me, in the ericsson service using EMMA, and this software can view the customize log...

is true? and if is true, any way reset the secret log in phone?

Pls help me

thank you
