Recoverig Kunteng controller's factory settings

[1carcarah1]

Is there a way to recover the factory settings of these controllers? The large controller (kt48svprkb-sjt02lb ) I bought with the Bluetooth dongle and the smaller one (kt36/48zwsr-ffF02) came with the bike kit and a LED 900s

Everything was working fine until I switched the input interface between the controllers, connecting the LED900s with the large one and the Bluetooth on the smaller.

The large controller would work without an on/off button, while the small would only work with the on/off from the LED900s. Now, when I connect any controller on the LED900s, it only blinks, and it's never able to start. Also, the Bluetooth dongle's light blinks and connects to the app while attached to the large controller, but nothing happens when I push the throttle.

I have fully charged my battery, but nothing happens.

Reading from the vendor's listing, I bumped into this:

"Bluetooth function must work with KT LCD display"

Oopsie.

Does anyone know the reason and how to revert it? Did I turn these controllers a paperweight?

There is a reset function on the KT controllers, but the only way to access it that I'm familiar with is with a KT based LCD. The setting is in the "C" parameters, and you're after C10=y to do a reset.

I bought an LCD8 before all that happening, it just needs to arrive, though. I'll report here if the C10 does the job.
