* had to replace at symbols because I am obviously sending email addresses or something... *
I'd also love to link the device so people can see what I am referring to if that helps... ployer momo2 should find the ployer.cn web.

I am sorry if this does relate to another thread, I am still trying to work out where I am at with this thing, and do not know enough, and I've been searching for days and days putting off posting and hoping it falls into place, but no luck.

I have a Ployer MOMO2 device, which is a cheap Chinese Tabet, no phone, no camera. Here is the URL to the device: .. well i would but cant link.

My problem is I need to get root access to this. I would ultimately like to have a fresh install on it entirely, as everything is in Chinese up until it boots into the os.

There is no Market app on it, and any websites that need flash try to redirect to market: which the device has no idea about. So, I need Market but this is only part of the reason. I cannot uninstall the default Chinese apps, and I cannot use them either.

I also know it has a cramfs filesystem, which is the reason I cannot perm root using z4root. And unfortunately, z4root also fails to temp root the device, failing and then locking up the tablet, or freezing it requiring a cold reboot.

I have tried various version of r4root, having read others have had success. Not so.

I downloaded rageagainstthecage-arm5.bin which is suposed to work with android 2.2.1, and executed it using a terminal app, which proceeded to fork processes and can adb. However, that is where the success ends.

The terminal freezes, as expected, and I force close it. Reopen it to check root, but it won't open. The only way I can access the terminal now is to reboot the device, thus losing any temp root access.

Ugh.

I've tried 1click, as well as other recommended once, but not having the options to boot into recovery/bootloader etc, I cannot complete any instructions on those guides.

I also just wanted to see how I could go about the process of updating the system, using update.img on the sdcard, not intending to do it, but to just gauge the process for now.

It detects the image but says it's corrupt and asks me to delete it.

This was the update.img I got OFF the tablet. It wont even accept it's own? Nah Im doing something fundamentally wrong.

I've been trying so many things, I'm lost.

I simply need to know which direction to attack this issue, and I've seen other rk2818 images out there that have been edited to include root access and market, so for those guys it's possible.

Can someone please offer any advice, keeping in mind I'm not well versed in this, and may require more than cliffs notes...

I really do feel as if I've made complicated something that does not need to be so.

Thanks in advance for any help,

Cheers!
