I used this one:
[ROM] EPAD 256M and 128M 1.9_88 rooted v0.3 WORKING MARKET FROM FLASH it was really easy!!!
How to Install
1. Turn off device, if the device is turned on.
2. Extract files to freshly FAT32 formatted MicroSD Card (up to 16GB Supported) under a folder/directory called "script".
3. Safely eject MicroSD Card from computer, put in device.
4. Boot device up.
5. You should see a screen that says "Tablet system update will commence. Plug in AC Adapter and DO NOT TURN OFF DEVICE".
6. Follow the prompts.
7. When device shuts down, turn it back on.
8. Turn on and enjoy root and Android 2.1!
Can't believe it was so easy! No flickering or issues as of yet.
