I have a tr718d tablet that is rooted and running a 2.3.1 ROM . it worked great and I tried to update it to 2.3.4 using android batch upgrade tool and it loaded and then at the end it said 1 OK 0 fail. Which is usually good. But it didn't do anything on the tablet and now it won't turn on, the computer doesn't recognize it, and the reset button doesn't work. If anyone has any suggestions I would greatly appreciate it thanks !!!!
