hmm, so i have to flash the same firmware i using in my branded phone(R1GB001)?

accually i have 2 files which is W850_R1KG001_FS_S_ASIA_LEVAN_CID52.DVT and W850_R1KG001_MAIN_GENERIC_CID52.DVT (both was in files_to_upload folder) i locate the files using phoneXS++ and when i press flash, a msg box appears and say PhoneXS++ stopped working and close after i press "ok".(this was done before i open this post)

izzit because i use vista premium so the program stopped working? or i put a wrong firmware?
