I don’t know if it’s normal but when I only had one resistor speed of 16mb was around 200mb/s and when it finished the benchmark it said that emmc was in slow mode. I added one more resistor and the speed increased to more or less your results and the message was gone.

I personally use 10K for pulldown now. As i once use 1K but then some of the unit sometimes boot directly to ofw (glitch failed) and sometime boot hekate. Maybe its specific by mosfet type as i use AON.
I got wierd switch v2
Yesterday i instal picofly
All perfect, try to reboot many time
And today, something wierd happening
After turn off, swith cannot turn on again
I left about 2 hour, and switch turn on normally
So i remove pico and every cable
Still the same, cannot turn on
Plug in usb charger only draw 0.2-.03 ma
I left switch while charging maybe like 1 hour
Turn on normally to ofw and usb draw 1,6a
What happen with this switch?

Yes 1k for each mosfet, parallel.
By calculation it should be around hundreds kilo. I calculate around 300K, but i still not yet confirmed it.
When the pico run, the firmware will configured the gpio as pulled down, read from rp2040 datasheet its around 80k ohms.

Seems the power problematic.
Might check this chip

Some time you need disconect battery charge soket from the conector then conect and some time press 15 sec and then perss one on power. Me be your pico fly glitch is or ps1 sp2.
I already did that, still the same
Even i press restart
Switch can’t turn on

Like short or just ic nearly dead?
Is charge cable charge when you flip it???
Turn the charging cord over and see if it charges from both sides, from the top and bottom.
Hi guys!
Can someone recommend me a a good soldering wire that doesn't have rosin core in it?
And a cheap but good soldering iron.
I done a v2 on saturday but because of the shiiit quality rosin core tin and weak soldering iron instead of max 1hour, it became 5hours of misery.

I checked the resistor, rewelded and replaced the cable, and the problem is still the same.

Theres two left:
1. Try lowering the resistor CMD in pico to 30-40 ohm.
2. Reflow the emmc.
Maybe theres copper/tin debris goes under the emmc that short circuiting some pin.
Use what others confirmed, is the safest route.so what should i order?
"confused"
Hwfly confirmed to work (1kOhm).
And 10k ohm also confirmed on this post
https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/post-10177922
I myself confirmed the hwfly flex.
Don't have time to confirm the hundreds kilo pulldown.

I am currently have no picofly installed devices.
Already sold the last picofly installed devices.
Still waiting for the rp2040-zero to comes from china, 3 devices are in queued.
I have broken sxcore devices at hand, will report back, if i could repair it.

I read the usb c power delivery documents. Basically the power delivered its detected according to the CC1 and CC2 pin of the usbc.
I've fixed lite whose have a weird usb too. The voltage i measured in Vbus is 0, when i plugged flashdisk. It should be 0 then 5V. I track the CC1 and CC2 seems okay, then the Vin between CC1 and CC2 is controlled by the cpu via 2 transistor. And its turned out the connection on the transistor is open because of corrotion.
In my cases those yellow box is disconnected, which it should connected.
The line in both transistor goes to cpu.
My guess is, the cpu could instruct/configure the power ic to give vbus to the device. Since the line disconnected, the vbus is not given.
Try to measure the diode value of the transistor, cap, resistor around it. And compare it to a good device. You might found a clue. For me, the clue is the diode value in those both transistor is different.

You can use it after buy it install one in my friend console lite with out add any firmware and it is working.
Yes I know they have firmware on them, what I'm wanting to know is if it is the firmware from here of if they changed the pinout so it doesn't work
I don't think that they will change the pinout.
Because they took the margin of revenue from the hardware not from the software. More people bought the hardware is better.
While the nintendo took the revenue from the software (games). They subsidized the hardware. Couldn't imagine how expensive is Nvidia Jetson, before switch is. Its like 2 or 3 more expensive than lite. And its without lcd, nfc, joycon, bluetooth, wifi, etc
That is why the N really strict with emulator and the mod, since it will cut their revenue income directly.

I have no other clue, other than the emmc is malfunction.
Maybe other people in here have clue or experience on this.

@HoTuan You'll need one that hasn't had its stock firmware updated in quite some time, for starters
