RP2040 2 flashes

[impy101]

Hello,

I have a switch V1 here that's giving me a lot of trouble. I have installed both a Picofly and a HWFLY and none of them want to work. I keep getting 2 flashes. Pretty sure they are fast flashes which suggests RST is not connected, causing the switch to start up normally, but even with the HWFLY I keep getting this problem. There are no torn pads from what I can see.

Any help is much appreciated.

pictures of your install will be helpful.
did you use same cpu flex for both picofly and hwfly install? if yes maybe faulty.

I've already replaced the cpu flex and that did not do anything. Here are some pics.

I've grinded away as you can probably see so that I could test for continuity and that was all fine as well, so I really don't know what's causing this.

it would help to see the cpu flex as well.
