Need some help please regarding flashing roms
sorry about this thread but i am getting a bit confused with flashing roms on my s2. my handset is not even 3 weeks old and i am already sending it back due to the drainage of the battery. what i mean by that is that i must of flashed the handset like over 40 times till i found the rom that would not drain my battery so fast. i tried cognition, villainrom, batista and everything and my battery was going like hell. within like ten minutes of just having wifi on and just doing my normal browsing my battery from fully charged went down to 85% and that is with data package off and hardly any widgets on. and all the time my display was the highest thing in my battery stats taking the most usage of my battery.
anyway i am sending the handset back and hopefully they will send me a new one. what i need to know is that can install any rom on my new handset once i receive it or do i need to find one which matches my firmware. ie say im ke7 do i need to find a rom with baseband ke7 or can i just flash it anyway say with kg6 baseband?]
sorry if my questions sound stupid i just do not want to flash for the sake of it if its going to harm my handset again.
