[Mr B93]

Hi.I've just bought an S3 locked on a carrier.I've unlocked it.But i want to change the ROM.It's with apps from that carrier that i don't want.If i change it, will it remain unlock?Or i need to unlock it again?

You're going to need to root the device and install a custom recovery so you'll be able to flash .zip files for ROMs and any other mods. I think you're going to have to root based on the carrier the phone was originally with.

A bit complicated for me...So i need to install a custom root.I can't install a normal ROM?And keep it unlocked?
