Thanks for your Answers.
i got my phone from a friend so i don't know if bluetooth woked before.
I will try to flash with gflash.
Can you say to me what firmware is the best working one with german language?
Do i have to remove the branding before flashing?
Can you add the firmware for my phone (MAIN:W800_R1BC002_MAIN_EU_EMEA.rar and FS: W800_R1BC002_FS_EU5.rar) because i can't download it in the download section)
regards
Mario
