HWfly failed installation on Switch Lite. No boot after desolder.

[Chronologics]

Hey fellas, hope all is well.

I recently attempted the switch lite HWfly install with no avail (that flex cable was ruined in the process) so I thought to cut losses and desolder the SP1 SP2 connector on the processor unit and remove the flex cable as well.

Unlucky for me, now the switch doesn't seem to boot at all (no sounds, no image on LCD) but the device does seem to 'turn on' as when I hit the power button with the battery plugged in the components do heat up to around 40C (104F) like it's trying to do something. Here's some pictures on the parts I touched with the soldering iron under the microscope. Does anything look wrong from these pictures? Or would anyone have any idea on where I could start the troubleshooting process? Very curious and eager to learn. Any advice is seriously appreciated.

Cheers mates, take it easy.

hard to see but these pins are pretty much data lines surrounded by grounds, so even a slither of solder between two pins is likely to break comms between different parts

you are missing this resistor 120 100 ohm

Hey guys, thanks heaps for the info, the missing cap is a bit embarrassing I'm surprised I didn't notice it. With your help I replaced the cap with a 100ohm one from an oled board that I had that doesn't work. Also looking back I noticed this bridge after you bought the possibility of others to my attention, these two fixes and it boots again! Cheers guys couldn't have done it without your input.

Additionally, is there a good place to get replacement resistors/capacitors for these machines? Or is donor the best bet?

If you know the resistance or capacity you can simply order an appropriately sized one off of Mouser or Digikey, whichever you prefer. They are dirt cheap and if you are working on multiple systems they are great to stock.

just dont go searching for 100 ohm capacitors when you need a resistor

Yeah that lol, know what you need otherwise you can cause more damage
