updating firmware of the controller

[cumhuronat]

I know that this repo is not the best place to find an answer for this but I wanted try my chance.
My DPG1C32 controller which normally has full features is modified with DPG1C02 firmware by linak as you can see from the below image.

Is there any way to reset this controller to its original firmware?

with further inspection it seems like this device has a nrf51802 soc inside it and the swd pins are exposed for (down/up)loading a new firmware.

But without having the original firmware it would be very hard to make the necessary edits with assembly. I'll just purchase a new controller from amazon :)
