i'm new in this stuff around the flashing, so i've got a question, if anybody can help me and advise me a complete course how to flash a firmware.
i've got nokia 6150 (NSM-1), my current firmware version is 5.23 (20-03-00). i'd like to flash new firmware version p5.23 (12-12-00) with language pack C.
i've got also 3 versions of this new firmware (all 3 are lang pack C), but i don't know, which i should use. is there any app, that checks correct checksums or something like that?
next, which flasher to use? i found different flashers (dejan, xp windls, knok b22, ...), but i'm little off-balance, which flasher to use.
another thing, is any sequence i should do before the flashing (i know about the backup of the old firmware, but another, like calculate something)? there are some differencies between flashing all the memory and only some part i think, but i don't know much about it.
if anyone can help me with this, recommend me any software what to use, eventually some links where to download flashers, firmwares, courses how to flash, etc. for my phone, feel free to reply
