Flash w550i

[riders4sia]

you can also use .bin if it is a File system and make sure to use fully charged battery

but in download section no .sbn file for w550i ????? can i use .GDF or .bin files??

In download section W550_R4CB020_MAIN_GENERIC_EL_RED49 is .mbn and
W550_R4CB020_FS_EUROPE_1_RED49 is .fbn.
And no, you can't use other GDFS except the one you backed up from your phone.
