Re:- Registration being asked for
The only way around this, if you have no Code, is to disable the request. The downside is that you will have to do a manual install of any updates you want to apply.
What you do is to root the Tablet using z4root or similar. Then, using rootexplorer, you navigate to system, then Apps. Scroll down to wowupdate.apk. Set rootexplorer as rw then re-name file as wowupdate.apkz.
This works on my SuperPad but I cannot be sure it is universal.
