yesterday, I bought Docomo SO-01F
This device is 4.2.2 and 14.1.h.2.119 build.
I found a link (http://forum.xda-developers.com/show...87&postcount=4)
but It didn't work.
When I try to system update(at setup), it said "Unable to start upgrading in an area where docomo signal is unreachable or during roaming even when Wi-Fi connection is enabled."
I just wanna kitkat(4.4.2) and Rooting my device..
