Can someone point of what I’m doing wrong, the red pointer is where I had the cpu
Do you know for sure that the soldering point was G, did you measure with dmm before cutting? Because in these cases G is soldered to the resistor close to mosfet.
Also, why do you have wires soldered on top of SP points?

I Believe your red point goes to the Drain on the mosfet,where your top sp1,sp2 solder point. You can check it with multimeter.
You should use the left side resistor as the Gate point/CPU
Thanks for the replay I’ll give it a try. I thought where I had it connected it was connected to the resistor already. But I’ll connected directly. And see if anything changes

I have a switch lite, with a micro sd problem, sometimes it recognizes it, sometimes it doesn't recognize it. I have already tested 4 cards, as I have a switch lite that is working normally. They told me that the nfcddr chip could have a problem so I changed it, but the problem persists. I took measurements on the slot line components are normal. I also noticed that when I tighten the screw it stops recognizing the micro sd. I need help!

I didn’t test it I don’t have a tester. I follow the traces. and the wires are there and the wires are because I’m doing the installation on the switch lite

I've never had such an issue with an OLED, I got a blue screen before, but not black. reason being; This was my first OLED install with my new station,SUGON A9, I should have practiced on a donor board to get an idea of its heating capacity.
How would you defeated *== and clk problem?

well its ur own fault why do u buy dat0 adapter do it the proper way and reball the emmc, specially if u offer it to customers.

these dat 0 adapter will always give u issues since there is no proper connection .
if u want a proper connection and not offer a half ass job specially when u make money on it then learn how to reball if u dont wanna do that u deserved to get scammed , as the matter of the fact even if u do it for ur self and use a dat0 adapter then its ur own fault.
A real tecnichian would never install a dat0 adapter and sleep well at night if he takes any pride on his work.

thats my 2 cents to all these discussions on the Dat0 Adapters
Wait a bit mate....if you don't have the skills to install correctly w/o reballing is not my business. In my country we will cal you handless. More than 1 thousand oled clients happy and my success is 100%. I offer lifetime warranty, don't needed but I do.
In the other side, seller sells 1 thing and ships another, this is scam, try to search in a dictionary if you know read.
For your interest I sleep very well and grateful by people here for my services, more than 20 years experience on aircraft electronics.
You don't know nothing about me kid. Don't want your respect but speak to me with education
Good night great thecnician

I already checked the solders near the micro sd slot and they are correct, it only takes the ground for pikofly. This problem already existed before unlocking with pikofly.

i mean specially this cable her and make sure u dont squeeze it under the heatsink so it doesnt break

if it was already before the install maybe there is a issue with the soldering points (cracked) on the sdcard pins or with the sdcard holder itself

I do not speak English so I do not know if you can understand me.
That job of yours is not the job of a technician.
Even if your soldering is excellent, you have a problem when you use a dat0 adapter.

Of course, it is the freedom of the "individual".
If someone claims to be a "technician", he should not do it in a way that causes problems ...

I have no chance to try, it's not with me. This video was made by the customer.
Can I reset the picofly when it's installed on the switch? Does it have to be powered or is a jumper enough even without power?
Sure its an instalation issue because it works before, can't remotely be done.
Most likely the Mosfet is dead, or any of wires has detached or cold join decided to quit:D. Need to hands on to fix.
Happened twice on me, and to prevent this kind of issue in future now i always fix the solder point with a hot glue and i move to mosfets with higher spec.
For a reset point/switch i think i have an idea if somehow we can put a mini push switch which accesible from the speaker grill. We can do it with magnet switch also (but until confirmed that firmware reset can revive the glitch).
Also move/rewiring the led to be visible at least the glow when you open the game card slot (this may be ill do soon).

I re-installed the chip three times and could not defeat it. I deemed it killed maybe because something went wrong with CLK. It was a Zelda edition, hurts whenever I remember it.
Any mistake in steps that we could learn from you? Will do an oled adventure soon.
