this is DEMO unit with SuperCID but S-ON, u can install every rom which u want... is only right idea how to do it. there is not any other solution, because is special ROM for DEMO units.
is it really that easy? No need to replaces cables? I have the international (or European) version of the One S. Very tempted to switch the battery for the One X+ piece!
is realy that easy, you just have to put up side down, because label is on...
even if u have supercid u still ave to install from ruu regular ASIA rom for this same region for wich one is OTA, and then u can download ota or install this one, in other case u will try tu install using fastboot ruu mode, and then u will update...
i think this is also JB
anywas someone share dump of ics and jb, but i'm not sure is a good idea to using dump without md5.
