After getting a second switch I was able to install the SX Core without a problem. I am not sure what went wrong with the first attempt. Some tips for other installers on what could have possibly gone wrong with my first install.

1) Make sure you discharge static electricity (I connected a strap to the ground of my soldering station) (possibly on tools too).
2) if you are using IPA wait a few minutes for it to dry before turning on the system (testing) (make sure to clean flux)
3) As mentioned before, check your soldering iron for voltage leaks and proper resistance. This document explains how to do this https://www.ipc.org/TM/2.5.33.1.pdf I did it with a multimeter. Voltage should be leq 2mV and resistance should be leq 5 ohms (according to Hakko)

Hope no one else encounters issues.

So my recommendation is to make sure everything as modderfoker told me and then solder the final cap
Dont try to solder and desolder alot, the cap will go down in 1 or 2 hits

my install is good, but im just trying to look for a doner cap or alt power to get that boy kicking

Updated to latest firmware and left a bit to charge, before I' ll try installing my SX lite on the new one.

Let's see..

Cleaned up..

...and finished soldering..

That was quick.

I'll test it as it is this time.. (without reassembling anything)

P.S.: All photos are via my Samsung Galaxy S7 Edge..

Kept flashing blue for a while but so far so good..

Everything is working OK (as long as I have it dissassembled)

I am not sure if this has been posted already but there is a workaround for missing sd card drivers after installing SX Core/Lite (I forgot to install drivers first on one of my installs).

SX OS should boot as expected but CFW will not work until the drivers are installed. To fix it just lunch OFW and the console will try to boot but will turn off. Simply turn the console back on and it will boot to OFW. Accept the prompt to update and wait for the system to reboot. That's it, you can create emunand and launch CFW after.

So guys i faced an issue, install was good, showed it over to several guys, attached the chip, kept getting pink pink pink, although soldering was good.

decided to unsolder thr chip, console boots to ofw normally, attached a new chip, bam got a green light and boot.dat, was getting my phone to take a photo, console restarted and glitched to pink.
Turned it off and tried one more time, the chip has no power this time and boots to stock.
Decided to test the cap for continuity and it was ok
Tested the smaller cap below found a short.

removed the chip, and tested the console, powered on and got a weird hiss sound, automatically powered off, tested for shorts on caps, and both are shorted

here is the before and after, if anyone can assist with this weird thing, as i tend to have a habbit of weird stuff happening at the end each time, and havent succeded in a lite yet

Pink is an error with the nand solder points. Use lots of flux and make sure the cable is connecting to both of the little pads it's next to on each solder point.

The bottom cap connection is how it's getting power. If the chip powers on, leave that part alone.

Are you using a soldering iron with temp control? With the issues you keep having it seems like your iron is too hot.

Ok but my solder points were good, and when i changed the chip it glitched green once, then the whole chip had no power
I dont think thats nand related.
Also the shorting of the 2 caps

I can remove the qsb if you think thats the issue in the morning.
But i highly guess thats the point.
