I have the AT&T Galaxy S3 on 4.1.2 and want to root for the first time. I've looked around and have seen that chainfire would be a good way for a beginner like me to use. I was going to do it, but then I read something that said the Bootloader had to be unlocked. I don't know what a bootloader is and if mine is unlocked.
I'm looking at buying an Xperia Play on ebay, and I'm trying to find out if the bootloader is unlocked. The seller says it is sim unlocked, but he doesn't speak good English and isn't understanding that I am asking about the bootloader. On my Nexus phone, there's a little padlock on the screen that shows what the unlock state is...does Xperia Play have something similar?
without knowing my phone's bootloader was unlocked by the shop in the 1st place!!!
it's currently 6.1.A.2.45 Root Status: Unlocked Bootloader = Yes...
after downloading the update, the phone shut down automatically while installing the update, and a brief recovery screen appear on the restart, the phone would still start normally but there's a notification telling me the update could not be
I know this is a very nooby question but i would like to know why we need an unlocked bootloader and what it could do for us. Ive read somewhere that without an unlocked bootloader you cant flash custom roms but that confuses me because we already have custom roms and cwm. Im currently running on avatar rom 4.1.2 and im wondering what other cool things i could have with an unlocked bootloader.
