Fixed. Thank you bro. It was exactly as you described.

can you show picture for further reference?
NVM, saw your post from other thread

This one drived me nut. I took a lot of parts off just for chances. Because it sometime could connect to the body i thought the traces are intact. Silly me spending a wholeday looking in vain.

I Normallly just flip open from memory side and then push left from right to remove the entire shield, which may save some hassle from cutting traces by accident.

where exactly was this cut trace?

That one from my customer . i use a very tiny pin to pry open the shield. I have received another one(oled) which could not boot and charged. The switch had been worked before on some parts. I changed the m92t and the switch can be charged at 15v 0.4a but still black screen. No short at bq, p13usb , max772 ,3.3v rail normal too. Another one is testing my nerve now @@

It nears the top side of the right joycon socket.

Hi,

When I Install a RP2040 based picofly to V1 (erista), switch glitches up in 1 to 3 sec
Erista is more like 15 to 45 sec.

I use fw 2.73

Is there something to check for this issue ?

Thanks a lot !

Erista always boots faster, different algorithm.
You can try booting Mariko multiple times (like 20), the more you start the more statistics the chip has.
If you have Toshiba eMMC, you can replace it with a Samsung one, they are commonly faster

Agreed to this, toshiba emmc are way slower in glitching process than the other variants. My oled glitches for about a minute, but samsung instantly glitches for like 1 to 3 sec only. Had modded multiple oleds with Toshiba, they all shared the same issue of long glitch.

This will likely cost you more cause these people self print these so they are not economically friendly.

If you want to self print you can use this though it will cost you more than the traditional one but you get the benefit of having additional lines easily connected. Designed to be used with RP tiny and zero.

------
Better just buy the v2 available in the market, they are A LOT cheaper.

Are you aware of other OpenSource Flexcables? little sad that there is no gerber for dat0, Lite or OLED...

Hello guys. I'm about to swap cpu from 2 boards. Do anyone know if this anti piracy ic is married to cpu or not? Thank in advance.

Never heard about it.
Interesting to hear your update about this.

I don't recommend printing any slide-in adapters because they are tricky to get right with variant results from PCB makers.

Unfortunately , upon taking this anti piracy off all the shorts on the board have gone. The previous repair shop seem to give up on this and sold it to me for 2$. I intended to swap cpu to my missing cpu board. But now all the shorts have gone guess that i have another alive board to fix now.

I will find another board to swap the cpu. I will update for you when i find one.

If this swap will fix nintendo switch boot to black secreen that will be very nice i have 2 motherboard one of them not tearning on and not charge i think swap some chip from working motherboard to this board will fix it. Im wating for your update thanks you.

That's the ASIC that handles all the traffic from the game cart.
Afaik, it is the same for every Switch and is not linked to the CPU.

I vaguely remember people having problems with the GC after swapping. More to do with the firmware.

Using a high-quality microscope camera does the job easier when doing kamikaze. @.@

hi any one have measurements of the clk cmd data reset . cpu .. ja all... in scale diode ? any schematisc for mariko .... i have issue only boot in ofw ...

need valor in diode scale the all point ... to confirmed is ok ... like cmd 0.500 ohm etc

Can you measure the exact distance? Best

Its 1mm from the center of the cmd line.
