Unless I'm mistaken, that's the UK 4.2.2, but rooted and packaged as a flashable zip. Flash it through CWM, not Odin. This bypasses the lock. I flashed a non-China 4.2.2 to my phone that way and it worked.
Come to think on it (and scan through through
this a bit), I don't know if "this bypasses the lock" is true. It might be that you have to go through the process of *failing* to flash a non-China firmware first. The process with my phone was:
(1) flash a non-China firmware
(2) gnash teeth when it failed.
(3) flash CWM, do Factory reset/Wipe data, do Reboot device now
(4) be surprised when the device did reboot.
(5) be even more surprised when the device claimed to be running the *new* Android
(6) putter along for weeks then months using the new android, sometimes getting mysterious reboots out of the blue, but whatevs because it all mostly works.
(7) then get a rooted flashable zip of 4.2.2 from xda and flash successfully through clockworkmod.
So I don't know if all of that was unnecessary or not. I'm pretty sure the "locked bootloader" is still there. Meaning, if I tried flashing a stock, non-China firmware now
through ODIN, it'd probably still fail. But flashable zips go through no probs. So I don't know what's up with that except that it works for me.
