I attach my breakdown of the register differences and my hacked .DL file (I zipped it because this gives you a basic CRC check).
@nikunjgoyal10 Flash your dingoo dingoo with this .DL, it should fix the problem. If not, in worst case you will have garbage on the screen (I doubt it) and will need to flash again with different .DL. Remember that if you choose a modified firmware with changeable themes like 1.20-pof you need to put the system folder on the dingoo first. HTH
DISCLAIMER: Of course, I take no responsibility for any damages caused by using this stuff. It should be safe though. I flashed my dingoo like tens of times before coming up with this solution. Bricked it a few times in the process and unbricked. I even plugged the usb out during the upgrade;). It appears that dingoo is nearly impossible to brick permanently.

The forum doesn't allow to attach zip files - so here it is:
