I Damaged a Convoy L4 Driver - Help/Advice Needed!

Flashlight Modding and DIY Parts

I’m sorry this isn’t a proper post, but I need some information that I GENUINELY cannot find anywhere else.

I’ve done my research, but it’s nowhere to be found.

My Question:

Anyone with a Convoy L4, or who has knowledge about the LD-34 driver, could you please test/tell me which pin of the microcntroller this trace connects to:

I accidentally destroyed the trace with pliers, and I now have no modes.

Thanks!

Just by looking at the pictures it looks like its connected to the pin one below the top left, possbily another pin as well. Do you have a multimeter? You can use that to check continuity.

Unfortunately, the problem is a lack of continuity:

I scraped a circle around the edge of the board while getting the brass retention ring out.

EDIT: Update, that trace is connected to a pin on the MCU, so now I still have no modes, but no idea why.
