Oh sorry If I wasn't clear i'm trying to unlock my bootloader so i could upgrade ny Android from 4.2.2 to higher with a Flash recovery on my Xperia l and i tried to do it a year and a bit more ago but didn't succeed and thought I would have bigger chance now but no and then I turned to this forum and asked for help here after many threads from all over the world
I'm willing to Skype if I need with any of you just to get it done, if you guys want then I'm up, if you don't wanna then I'm okay reading and try and understand myself whatever you will write.
So the thing I needed help with at first is boot unlocking
