Did I kill my brand new OLED switch?

[Nikaia-Repair]

Hello guys,

It is my 1st time posting here. I've already found some fixes for my issues here (thanks to y'all btw) so I thought it would be the right place to ask.
Long story short, I tried to mod my brand new OLED switch with a HWFly modchip. I bought 2 different versions to be sure.

The 1st time, I think I did all well but the chip wouldn't boot and the switch was booting normally, not in the "No SD Card" screen. I checked every connection like 10 times so I thought the chip was faulty. I then proceeded to change the ribbons for the other version, but a capacitor broke off during the process (next to the CPU). I put it back in place, the console was working fine after that. I then proceeded to put the new ribbons, all measurements looked good:
A, C, D, 3.3V were 0.75V in diode mode
B was 1.5V

When I tried to boot, the chip made a blue light signal, ther purple, then nothing. I had to unplug and replug the battery to do it again, just for it to do the same pattern.
Then the switch wasn't working anymore, no normal boot at all even without the chip.
My voltages in diode mode were then :
A,C,D 0,45V
3.3V 0.75V

Now, I'm afraid that I killed my CPU; every capcacitor on the picture that is painted in red either show a resistance of 0 or 1ohm between its 2 points:

Do anyone know if it's worth the time to try to repair it, or should I only keep it for parts? Could it be another chip that died?
Thanks by advance for your time !

I'm so devastated

Stray solder ball somewhere ? Maybe under the Apu.
Shorted capacitor due to heat from soldering possible, try removing the ones you soldered too and see if the short clears.

Thanks for your answer !
I don't think there is any solder ball, i've been very careful doing it, but I'm going to check anyway.
I've already removed the ones I soldered, which did not make the values change. I may try to remove all capacitors and see if it changes the problem before putting them back in place.

Stop! Please measure the ohm values against ground. Just the two capacitors SP1 & SP2.

=** eMMC init failure during glitch process

Pictures of your setup would have helped as well.

Hello, thanks for your answer

My Hwfly setup? i ripped it all off the board hoping to at least make it boot normally...

If i'm not wrong, one side is always on ground?
I'm going to try tomorrow but I think it will be between 1ohm and 1.5 ohms for what i've seen today

Yeah, that might have helped find what was wrong. Another thing you could do is upload some actual pictures of your board in all the places you touched.

However, I would do what MoeXzl asked above

this is why I had a professional do mine. cost me a lot of money though.

I will do that tomorrow morning, I don't have it here right now. thanks for your time

The worst thing is that I did at least 3 OLED Models for friends of mine before and never ever experienced that kind of trouble. I did 15+ classic switch also with no defect rate.
When it's one I buy for myself i cant manage to do it, but when it's for others it's perfectly done
But that's better like that I think

I know that feel. I have done some successfully then damaged a couple or a few. Not the OLED version though but the original and the lite.

Hello,

Here are some pictures.
As you can see I dismounted bot SP1 and SP2 capacitors.

Stop! Please measure the ohm values against ground. Just the two capacitors SP1 & SP2.

1.5 Ohms on each one to the ground. The capacitors were dismounted while measuring.

Any cut traces around here?

the clock trace is in bad shape, after several soldering tries... i have to do a repair on it, do you think it could be the source of the problem? I thought it wouldn't affect any capacitor value...
