Ok I'll let it charge up..and dump the firmware from it....I think the only thing is I have it rooted and the market installed on it....
Oh....I just downloaded that copy you're speaking of for a backup since I never backed mine up yet....It was linked here and on another site I have with a huge list of firmware for Chinese tablets also...
You have to have the tablet rooted to be able to make a dump of it. The fact Google Play is on there really isn't a big issue either. That may make your dump more attractive since it eliminates the need to put the Play Store on the tablet.
I did a factory reset on it because I never use it really....But I wasn't thinking about the rooting because that's always standard for me to do first thing...lol...But I'll dump it later and dropbox it....
