Help How to hard-reset? (Witstech A81-E)

[foxbox]

Hi,

I've got A81-E from JTShop a week ago. It still has many problems and
I have been trying to solve them. Now I would like to know how to hard
reset the device. I need to roll back the device to the factory setting.

Could someone tell me how to do it?

---
My main problems on A81-E are:
1. Display does not rotate automatically.
2. Bluetooth does not turn on.
etc..

Display is not going to rotate automatically.

Have you updated the ROM?
GadgetsAndTablets.com - Login is the newest rom. You will need to sign up with them to get the newest version. You format a memory card put the files on it, and press the left volume and power key at the same time. It is pretty well that easy. It will wipe everything.

Another forum called slatedroid has a section called Nationite MIDnite. I am using a custom rom from there.
Nationite MIDnite Firmware / Development

I haven't tried bluetooth, but it "should" work.

Sorry for the second post. I had to do some deep goggling. Most apps are made to toggle auto rotation on and off.

I had to pull it off a file sharing site, but Cynosurex makes a program called RotateD. You have two icons rotateL, and rotateP.

Thank you very much! I could do what I wanted at this stage.
In my case, the key might be to use a formatting tool 'hpusbfw.rar'
which can be obtained at

If you go to the GadgetsAndTablets.com it instructions are in English.

The HP file is to help you format your flash your memory card.

0809 is not the newest ROM. The newest is 0823
