[Q] Xperia Z, sim locked, 244 version
Hi guys! I just bought a used xperia z and it is updated to 244 version. I want to get rid of the carrier lock because I have no idea what carrier it is, and when putting my sim in the phone it just tells me "emergency calls only".
So, I have read about rooting and unlocking bootloader etc. What I have not figured out is witch of these actually unlocks the sim
I have no warranty so I don't care at all about that. Is it a good idea to root and unlock?
The problem is that when entering service menu and looking at SIM lock its like this:
 Network 0
 Network subset 0
 Service provider 0
 Corporate 0
 SIM 0
Am i screwed or is it possible anyway?
I also got stuck at flashtool because my windows8 64bit has issues with usb drivers. I think I need a windows7 32 system to do it right?
PS. I can also buy the unlock code but if I read correctly because it now says 0 tries left that is no longer an option!?
