Hello everyone, I just now read this 3D, we do have one like it here ww.androidiani.com/forum/tutti-gli-altri-tablet/74581-flytouch-4-tablet-10-con-modulo-3g-integrato-prodotto-cinese.html and we use this tablet with ups and downs since January,only difference is that it is compiled from jackie and not wanghua.
in Italy as flytouch IV comes with 3G, we believe we have found the original ROM address this 66.228.126.56/~rom/download/rom/10%22/CEMX2203G (tested and working) we found according to the product code given by the seller (my efox) the features are
TAB 10
v2.2 2011-09-21 (011112)
2.6.32.9
root@jackie-desktop #106
FRF85B
I hope to be helpful and sorry ....... the translation is done with google
