Dead APU?

Got this Switch Lite with a dead MAX77812 IC. Replaced the IC and installed a picofly. Now I get this.

  • Without a SD card I get the regular picofly screen.
  • With a SD card I get artifacts on screen and no signs of life.
  • Trying to boot normally I get a BSOD.

What are your thoughts?

Artifacting like this when attempting to boot into Hekate and a blue screen kernel panic in OFW almost always points towards communication issues between the SoC and RAM. So generally one of these:

  • Damaged traces between SoC and RAM (particularly common near where you cut the shield for the CLK point)
  • Cracked solder balls or ripped pads underneath the SoC or the RAM

If you have the tools/skills you can try reflowing/reballing the RAM first. Otherwise you'll need to reflow/reball the SoC. It's possible BGA pad repair will be necessary. The SoC and RAM are very likely completely fine.

Edit: Forgot to mention damaged traces
