Unlock hint for SGS4 Sprint USA - SPH-L720 MJA is needed.

I'm in fighting with one SPH-L720 - Sprint from yesterday - come updated to MJA release ( Android 4.3 inside ) and enforced state... so - in fact can be flashed, can be rooted, can upload custom recovery and is possible to update to prerooted rom, but kernel cannot be downgraded, custom kernel / for example - http://ktoonsez.jonathanjsimon.com/s...11.14.2013.zip / brick it, GooglePlay edition ( for example Download GalaxyS4/SPH-L720/roms/GooglePlayEdition/Google-Edition-Stable-v1.zip at DownloadAndroidROM.com ) power phone but is far away from working state and cannot be unlocked.



So - fact is that upgraded bootloader make not possible to downgrade phone. Used from me tricks for European SGS4 do not work for now, so - if someone have ideas - let play!...
