Chinese tablet pc (boot loop)

[sufyandawood]

Hi XDA

I have tablet pc which is been caught in boot loop fir three years , i have taken it to the market , many people have seen it but none can fix it as people generally don't know how to backup stock ROM from the device it self , the only way they know is to flash a new ROM on to a tablet or phone , here in Karachi, Pakistan.

here is the specs of my tablet PC

On the bottom right corner the green light is on , on the left side of the menu screen the status is this :

Error : Don't install utils

Error : TotalBytesPerChunk not found. Set default page/spare= 2048/64 !!!
unknown ROM structure , back up not possible.

also on root , back , recovery menu all buttons are visible.

Please advise if you guys can help me . thanks in advance.
