If you installed that version (.49) via OTA, prior to unlocking the bootloader via sunshine, assuming you have the xt1254 (Droid Turbo), then you are out of luck. If you bought it used, you can check to see if the previous owner unlocked it but otherwise you would need to sell it and find one with .44 or earlierCan I root if I'm on 5.1 (23.21.49.quark)?
