I really don't know what happen to my tablet, it's new to me. My Mom bought this to me as a gift for my birthday, it's second hand by the way. My mom bought it from her nephew, and still in good condition. So when it already ship to us, everything is smooth and nice, I can download games and everything. But when I download toy defense on my tab while playing Family Guy, it froze. So I press the power button for 8-10 seconds to power it off(by the way the freeze this its the second time it happen to me, but I just turn it off and walla, it fix). But this one it's strange, I turn it on, and for 10 minutes it stuck on the android logo. Now I go to the recovery to factory reset it, and wipe the cache. The cache is fine it really wipe off, but the factory reset I just hang to the recovery and nothing happened. So I download a cwm to factory reset this, wipe cache and delvik. And thank God it works. But now this is the problem I encounter when I open my tablet, it had no internal memory as in 0, so I can't download nor install apk course it to be installed to the internal. And that's not the only thing, every time I Turn off my tablet and turn this on, it just like reset again, the instruction, and even my gmail account I need to enter it again, every time I turn this off. So I hunt for the answer in this forum and in saw the dump files for my tablet, risking it if works. I Download the dump files, so flash the cwm to back up there's another problem when I backup "can't attach mtd5". So I just skip the backup and continue to the flashing of dump files and there also a problem "another problem about mtd5." I find for some solution on it but i'm helpless. By now I can use it, but download apps only the browser and some stock apps. And my tablet is not rooted. I didn't modified this. Please anyone , encounter like this, how you solved it? Please help me.
