Nicla Vision issiue after soldering

I have a strange issue occurring with my LED on the nicla vision. Its blinking in all colors in a high frequency. The Issue was first spotted after soldering a pin. Beside that hitting twice the reset button works. After reinstalling the firmware the nicla vision disconnects, a message (No open MV Cam found) is shown that no board is detected and the LED flickers again like crazy.

Is it wasted or anything I can do about it?

Uh, might be. That LED blinking like that means something in the boot process failed and the system went into a fault handler. openmv/src/omv/ports/stm32/main.c at master ยท openmv/openmv (github.com)

If you could undo what you did that may fix it.
