See section "Tips" in this topic and here http://www.slatedroid.com/topic/42424-712-dual-core-ics-jb-custom-firmware/Well I apply the EN03 with success and all work fine, the icons look different somehow, better, the task manager too, the battery work fine, the WiFi I can't prove because I don't have signal, my WiFi router is dead.
Some new apps like BatteryDrain, CPU Awake and .GScript, I don't know how is works that apps, I will find out.
I find a new option in languaje "Spanish (United States)" and works fine, I think works better.
The Base version said is 1.4, in the EN02 said 1.5.5 I think, why is that?
You think you can made a custom rom for the Onda v712?
Well, I am curious about JB, looks amazing, I will try it.
Thank you valkoz for all your effort, I am new in this of Android and tablets and so far, your work is amazing.
The only dissapointment with this tablet is the bluetooth the lack of it.
