Like i said - i debranded and unlocked this phone by myself. Phone was on orange and sim unlock procedure was successful and it was fully unlocked. Next step that i took - debrand. With A2uploader i flashed firmware with Sony Ericsson genuine to get rid of Orange crap. Everything was successful but with no network coverage tho. Then i used SEUS (sony ericsson update service) with created manually CDA file (customize_upgrade) placed in tpa/custom/preset and then ran SEUS - update was successful and i still get this no network coverage message. Used D-ultimate unlocker (paid service) with Direct Unlock(+Sec. zone rebuild) option - still the same problem. I don`t know what to do next. I`m confused to be honest. Some people said that my GDFS file is corrupted and can`t be restored properly without SE support.
