Hello, I so hope someone can help. I just updated my galaxy tab 2 7 p113 to Android 4.0.4 UEBLH2. That was done automatically from samsung updates. I wanted to then install the newest update to 4.1.1 jellybean. So I download it from this I found. update-galaxy-tab-2-gt-p3113-uecli4-4-1-1-jelly-bean-ota-test-firmware. I put the official Android 4.1.1 UEBLH2 Firmware on my sdcard then held down my power and up volume and installed it. HOWEVER, it never finished. Now I HAVE NO USB CONNECTION and NO BOOT UP. Just black Since I dont have usb connection I cant us oden. CAN ANYBODY PLEASE HELP? I still can put files on my micro disk card and then put sd disk in my tab and use the power button up arrow to install something but I tried installed clockwork mod but that did not work. Iam out of ideas. P.S. My tab IS NOT ROOTED so its blank screen and no usb. I tried updating back to original rom but that did work. Thank you.
