I don't believe it - pretty much each part of that firmware name seems to be 'older' than .136.
11.3 is older than 14.2 - and A.0 is older than A.1 - the only thing later is .681 - but considering the first two are older, the last part is irrelevant.
Had it been 14.2.A.1.681 - maybe we'd be talking.
However, 14.2.A.1.142 is an interesting prospect.
Confirmed! It is official 4.2.2 for zu. I am asking if he can dump the OTA update package for us.
Got it flashed, but no kernel I tried would boot it, didn't even get to boot animation. They all hung or bootlooped after the Sony logo.
We need a boot.img please
