[Xperia Z2 Q&A, Help & Troubleshooting] Ssseebaaa:
Hello

I have problem with my sony xperia z2 i lost cell radio because radio is off... I don't now why but it is...

I try reinstal system many times reset all values and it don't work.. to time when i flash android 4.4..2 (or 4.4.4) and flash this i edit this flashable zip and this working but when i update to lolipop(5.1..1) radio is still off... i realize binary( radiooptions) for kitkat is difrent than lolipop. At this website is source code but i can't find compile binary to lolipop.. I be very happy if someone can compile radiooptions for lolipop or know how to repair this "bug" because after many attempt i don't now how:D

PS: All application to turn on cell radio don't work...

PS2: Sorry for my English...

code in case of...
