Totally wiping phone before flashing rom.
I've read back and forth on different forums about this and it's still not clear to me so please enlighten me.
Is it necessary to totally wipe the phone, formatting and stuff like that when flashing a new rom with flashtool.
I've read that in some cases ppl had problems with old stuff still beeing there.
And next question how do I do it with flashtool?
