Moja zawartośćI have sony xperia z c6603 kddi japan with no signal problem after following this tutorial: see post "https://forum.xda-de...inish-t3069814"
I hope I can fix 4g network after following these tutorial. But after flash "C6603_10.5.1.A.0.292_baseband_v3.ftf" file, there is no signal at all. Anyone can help my problem? unfortunately, I did not back up TA file before, just dump TA file.
