Hello, maybe someone has problems withor firmware DM7033, ES777A or other OEM as Wortex R7 "? , Well, this link update.zip | Uloz.to can find a solution, it is a "update.zip" of 83 Mb which I have experienced problems that were fixed in part, the firmware is not complete, it is rather a patch but that apart from solving a problem and allow the boot can be used to include him the CWM recovery to replace the original, or include him the root directly. Anyway, I already started moving into recovery mode (power button + back button, to exit the menu key, press triangle and we're in recovery, the key point we descend back and play a flash option "update.zip ", we go to the folder from the external SD where we have placed the file" update.zip we have just come down from above link you provide. It boots normally and two little problems that I solved and then, rottee the tablet with the famous "SuperOneClick" In short, as I have left my other aparatillos Android. I hope I have been helpful. Greetings to all.
