Tore off DAT0 pad during PicoFly install on Lite

[ZephyrOpus]

Hi everyone.

I attempted to install a PicoFly into a Switch Lite. Unfortunately, I ended up tearing the DAT0 pad right next to the EMMC shielding. Are there any alternative points, or is this Switch FUBAR'd? You can see it in the attached picture.

Any help would be appreciated. I would also like to know what iron tips you guys use for such small points.

Seems like you damaged the pad on the left side, which goes 2 layers down and connects to dat0 ball under emmc directly.

Can't see clearly in the picture, but if there are still some remaining copper on the pcb, you can try to solder to it. Otherwise you need to desolder the emmc chip and wire to dat0 pad directly.

I found a diagram of the various layers of the motherboard. Should I try to expose the trace using that as a first step?

Hey, I have the same situation but on the Mariko board.
Is there any nearby copper that I can solder to?

If you carefully scrape the via (below the ripped pads) and the line, you can add a jumper wire.
If you destroy the via, the repair will be 10x more difficult.
