I have the same issue. i had my w910i branded with t-mobile but unlocked. i was using O2 network. couple of days ago i debranded it with the help of A2_CDA_File_Generator_v1.06 and A2 Uploader. then i ran SE update program and get the latest R1FA036 version. but last night i have found in this forum that there was another version 37. so i was dying to get that. and eventually i managed to get it, but now SEUS doesn't work with the phone. and also i have lost few themes in this new firmware. Elipse is one of them... so how can i get the SEUS running with my phone?
