hi to everyone...
i have been looking around for a while and i read so many threads in your beautiful forum, but i didnt find my case...

my phone is a K750c CID 36 bought in china a few years ago.

lately it got crazy a bit, once per day i have to restart it coz ringtone, wallpaper and several other thing disappear...

so i decided to try to refresh its firmware with a brand new one =)

i tried the sony update but doesnt work, it doesnt even recognize my phone...

i made a master reset... but nothing changed
so im here for the big step... hehe

i wanna flash it to make it w800 (of coz still chinese version)
and i read somewhere there's some patch to make the w800 flight mode more functional, such use also videos and games... is possible?

i already downloaded:
W800_R1BC002_MAIN_CHINA_CA_RED36
W800_R1BC002_FS_CHINESE_RED36

right files or wrong?

thanks!!!
