Guys somme app conflicted with the android boot, so when i start the tablet model MID7020 he gets stuck in android logo and dont go any further, like in this picture: http://images.orkut.com/orkut/photo...YpxfHwnkAm1T1UGApnlISMHc8wAj9Owshvx0jj5EK.jpg I didnt root the tablet, the system data and firmware its original, probaly some app conflicted with the android, and as result the tablet dont start. So i used ADB in android stuck screen, and adb recognize , i was able to do some command like reboot and pull the system files, but i dont have root acess and cant root the tablet because it dosent start. I was able to do this : adb reboot recovery , and the tablet started in recovery mod, like in this picture: http://www.imgfans.com.br/NR/Out11/12/th_IMG_2175.JPG http://www.imgfans.com.br/NR/Out11/12/th_IMG_2177.JPG I can navigate trough the options ( reboot system now- update from sdcard- wipe data/factory reset- wipe cache) BUT THE PROBLEM IS i can select the option , i can navigate with volume keys (up,down) but the home/back button when pressed just get back to this picture : http://www.imgfans.com.br/NR/Out11/12/th_IMG_2175.JPG when pressed again shows the recovery menu options again. There is any way that i can do factory reset using ADB without root permission? What can i do?
