Quick questions:
- what's the total thickness of the board? Nevermind this, just saw it's 1.5mm.
- for USB flashing we just need to solder the 4 wires, right? So I presume that the LDO for converting from +5 to +3V3 is present.

Hey, no belly criticism in this thread please. The only form of body shaming we will accept is calling people out for not wearing pretty nail polish in their videos.
Q: rp2040 boards support
A: WaveShare 2040-zero/one, xiao-rp2040, adafruit itsybitsy (Pi Pico is not supportedfor now)
Q: GREEN, but instant reset
A: Clean flux near the RST point
Q: Do I really need 47 Ohm resistors?
A: You can skip them, however in this case you will have to use emuMMC due to the line interference, sysNAND would not boot (sysNAND data can be damaged).
Q: Does the firmware has learning? How to reset statistics
A: Short pin 0 to either 1 or GND during start for chip reset. The statistics is collected each boot. The more you start it - the better it boots.
Q: open source?
A: no
Q: why you made it?
A: to prove it possible!
Q: run Atmosphere?
A: no piracy
v2.5 firmware had a bug with BOOT0 corruption. To recover it:
- boot "Full Stock" using hekate
- update to the latest official firmware over Wi-Fi
- boot "Full Stock" using hekate
- perform a full system reset
- show firmware information
- update firmware from SD card (place update.bin into the root folder)
- rollback to the backup firmware slot
- reset learning statistics
- dump / write sdloader
if you have an rp2040-zero from waveshare/ali then it has a neopixel. It is used for diagnosing proper firmware flashes as well as console glitching. If you plug it in, and flash the uf2 firmware to it and immediately see a red light after flashing (this is not the same as flashing, then unplugging and replugging), then no rgb jumper needs to be made. If on the other hand, you get one quick green flashing light, then you need to bridge the jumper pads indicated to swap the LED colors for proper diagnoses capability.
Hello guys,
Whats the meaning of the detection pins on the xiao-rp2040?
Is there an LED detecting if flashing worked correctly and if all the pins work in order like on the waveshare zero?
There is no definitive answer to this issue. Could be soldering issue, maybe a bridge somewhere, maybe didn't clean the flux, maybe the wires are to long.
You can try to add second 47r (so 94r in total per line) resistor to CMD and dat0 lines (but not on the CLK).
The best way to go about it is as lightninjay suggested, read the guide and go through this thread, your answer is most likely hiding here
Reporting my RP pico successfully glitching after being cut as per @rehius and @Dee87's diagram.
Looks nice for a proof-of-concept. I came to notice that the Dat0 point on RP Pico is very fragile so I engraved a trace right next to the RP's chip, this made me keep the other side of pins that would have been otherwise cut, but I needed the ground on that side to not make it messy next to all the resistors, not to say it doesn't look messy anyways lol.

Thank you @rehius and @Dee87. You guys have been very helpful and responsive.
Also, I would suggest you take the 3.3v from this point.
It depends on your soldering skills, but I had some trouble trying to solder to the original 3.3v (top of the capacitor). I almost damaged the cap, so i used the one on the emmc board.
