You meant locked bootloader right? You can flash Sony Stock ROMs only using flashtool or root and install recovery and flash them. No custom non-sony ROMs though.

You can use any Rom that is based on a stock firmware and kernel.
Make sure you have cwm recovery to flash Rom

i heard you need to be on stock based firmware to install the recovery,
but you can flash on other roms and manually flash the kernel or something like that
im not too sure,

BL is already unlockable, one unlocked u lose all DRM, there is no need for exploit.
Root was needed just to push the recovery to the stock kernel.
And CM uses a completely different kernel than the stock and the only way to flash it by unlocked BL

Exactly. I'm not sure of the chances that non-unlockable devices will become unlockable. If I said any amount if time I'd be making it up :/
One of the devs said that Sony bootloaders are locked up tight though...

The solution to your question is flashtool. Kindly search for it and you will get a tutorial here.
You need to first download the stock ROM to which you want to upgrade and then flashtool will do the rest.
Hope it helps!

Just look in the title for [LB], or if it's based off stock Sony FW it should work.
You'll find all roms for locked bl in the development section.. Original android dev is for custom roms. Go explore. It's not a hard job. Plus there aren't many. Just a few brilliant ones.have fun. :thumbup::thumbup:

No, you dont need root or unlock bootloader.
I did that 3 days ago, my xz runs better now, you need flashtool,drivers and the rom you want to flash
