Help stuck on com.android.systemui

[Davros1959]

Allwinner A33 chinese tablet
4.4.2 kitkat
stuck on com.android.systemui
Tablet is rooted, USB debugging is enabled

I had issues from the day i bought the device. the seller advised i should root the device and alter the build.prop file to enable certain features.

I made a backup copy of the build.prop file to SDCard, altered the build.prop file and now I am stuck with the device in a constant loop, com.android.systemui has stopped.

I have booted in recovery mode and have attempted wipe and factory reset. This has not made any change.
I have forced a factory reset from PC using ADB. The tablet appears to be resetting and reboots, but cannot change the error.

I have loaded ADK on PC and can see the build.prop bak on the SDCard. How can I copy this file into the root (or system) folder and overwrite the faulty build.prop by using PC?

Has anyone any thoughts? Tablet is going in the bin more than likely.

Advice on Chinese tablet from someone in China:
No one knows, put it in the bin. The seller advised you to root the thing and alter system files on the day you bought it, that was a good start.
