Messed up SP1 and SP2, killed my Switch?!

[fwizbee]

Right before I start the Thread I´m not new to Microsoldering, just messed up for the first time

Any Advice/Help why the Redmakred Circles are shorted to Ground even if the Battery is disconnected?
If I connect the Battery the whole bottom row is shorted..... and the Switch wont turn on.

But......

If I bridge the SP1 Point the Switch turns on, I can see the Backlight and the CPU gets Hot and makes strange noises...

I dont know what to do anymore

The switch would boot up without the cap over SP1 or SP2 but not bridging them.
BTW, those are low impedance points which is normal having low resistance measure or beeps on DMM

Maybe something with the EMMC Board?

i had similar problem and it turned out that it was soldering problem on the emmc board. I resoldered all emmc solder points and problem was solved

hello, I installed the rp2040 on lite but during soldering I lost the sp2 capacitor, I removed the rp2040 cable the console works. the question if I want to put the rp2040 back will the sp1 be enough, does it work without sp2 and why does the console work without sp2? THANK YOU
