The only difference between the wifi and 3g versions are some drivers to make the 3g modem work....otherwise they are compatible.
If you have a 3G tablet, but don't use the 3G feature...you can flash the wifi ROM...the modem just won't work.
If you own a wifi only version...you can flash the 3G version. Since there is no 3G hardware, you should have no problems...other than a slight increase in battery consumption because of some extra processes that go on in the background. Deep sleep will likely not work.
Lately, Pipo has been only issuing one version of their firmware for both.
I looked at the Russian ROM...and I think I will pass on it for the moment. I will just wait for an official Pipo release for my ROM.
KitKat is pretty sweet on my U8 tablet, but my most recent RileyROM 4.2.2 version is the most stable ROM for the M8 Pro at the moment.
