I had the same issue. so I rooted it using kingsoft android root software. Then, i unlocked the bootloader and flashed the kernel provided by doomlord with cwm recovery in it. then i used androxyde flashtool to flash the japanese firmware which had gapps preinstalled i think. If not, u can just flash gapps for jb. Or even custom ROMs and gapps.
Also give fqrouter2 app available in the wandoujia store a try to access restricted sites incl Google. U wont need it for playstore though. Just for fb and Google +.
