D4V2 with KR2 driver, update?

Hey guys. I bought a D4V2 and had hank install a KR2 driver in it. I have the cable as well as the phone app, but I don’t know which mcu…?

avrdude will output mcu information if you run it without flashing argument.

It’s 1634: https://bazaar.launchpad.net/~toykeeper/flashlight-firmware/trunk/view/head:/ToyKeeper/spaghetti-monster/anduril/cfg-noctigon-kr4.h#L3

I’m 100% unfamiliar with the app. Is there a thread on here or something with tips and tricks like you mentioned?
