Sadly you likely damaged something.
If it is very early (shut off in less than a second). It might be power related issue or some critical signal is missing.
Since cell didn't even start yet.
Data beginning offset of each file must be at least 32 bytes aligned (16 may also work but not tested)
If you don't you will brick, because loaders require minimum alignment to transfer the data to spu.
My coreos tools...
Try shorten the wire, ensure that CMD/CLK is soldered to correct pico pin
If still doesn't work, try new ground point that require short wire length
If still doesn't work, this time try new pico, maybe regular version.
If still doesn't work, then it won't work and nothing I can do.
Never understand why it even called Nofsm in the first place.
All you need to do to install CFW is patch isoldr and iso module to bypass pup check.
Which is always done on CFW or MFW builder.
So you just take CoreOS directly from CFW and flash it. dev_flash doesn't matter.
GND is a bit too thick, maybe try the one that you use for CMD/CLK right now.
For routing you will need to figure it out yourself, or watch some youtube and see how they did it
SC is normal. It should be around 20-30 ohm to ground.
This is about wire resistance, length and routing of CMD/CLK and GND. This is very important.
I said shorten the wire so just do it. GND is the most important one
Better routing too.
You also didn't use 0.1mm magnet wire for CMD/CLK as...
Your SC wiring is good. Do not touch it
This is CMD/CLK wiring problem, not board damage but rather solder to wrong pico pin or wire resistance is too high or pico is bad
Shorten ALL wire as much as you can. GND is the most important
Just uploaded a new uf2 hotfix (qcfw-20260228-release-2)
If you have issue with syscon terminal newline or command buffering, you can try this uf2.
It should work now
It's time to announce this:
I have no plan to rebase qCFW to 4.93 or newer
Since I checked PSN login and it still work fine (because Evilnat adds fw version check bypass patch already).
So there is no need for it
Did you install stagex yet?
Bootloop will caused by bad or no stagex installed. Or CMD/CLK wire is bad.
Check if CMD/CLK is soldered to correct pico pin.
Since your console still work without modchip, CMD/CLK resistor isn't damaged. But wire may be wrong.
Idk why but from what I read so far, you seems to assume that syscon somehow has the keys and by setting certain eeprom byte will make it print that key.
This is not true. Dumping is performed by Stagex. It watches data transfer between lv1ldr and encdec device. With static key known it is...
