Hacking Hardware Picofly - a HWFLY switch modchip

[Nephiel]

You mean something like this?? Including the blue flashing, I get in total 7 blinks

Exactly. The blue long blink would be
= USB flashing done
and the 6 blinks are 3 attempts of
** RST not connected

@Myst0gan It‘s 0201

I going to attempt a kamikaze. Any tips from successful installs.

I just want to let you know that if you have a v1 flex and you need to use it in a v2, you can do it but you have to use the i2c undervolt hack for it to be completely stable, since a few days ago I made a v2 console and everything is fine although after The 3 turned on, the chip only gave an error (==*) with the i2c undervolt hack everything improved

I've installed a picofly on an OLED, everything works fine except for the right joycon rail. During the assembly I forgot that the black door was closed and I shove the flex cable insiside the port without noticing it (battery wasn't plugged in). The port, rail and the flex cables seems to be fine, I don't see any physical damage or bent pins... Any idea where to look for the error??

@abal1000x Thank you for providing the NAND chips. I'll take a look at it when I get the chance.

All those marks look like damage to me, hard to tell from the picture though... is there any gold left under those scratches?

Hey i got curious now

You said V1 flex can work on a V2 board

So, do v2 flex can work on a v1 board somehow?

Also may i ask, where i can find more info about the i2c undervolt?

Sorry for bothering you but you give some hope while im waiting an aliexpress v1 flex for my v1 board

You should try a little amount of conductive paint over the scratches

I agree about the picture seems to show the scratches are deep and there is no gold plating left

Something like this for V2-to-V1

Working on a switch lite and using a flex cable. It appears to be necessary to cut the CPU shield in order to get the top of the flex cable out without putting pressure on it.

Can somebody confirm this?

Further, I'm doing a V1 and a lite. Will other cuts be required to any other shielding? I'm seeing mixed info.

You're right, there is none, I'll have to tin them I've tried with a rail from v1, it wasn't working either, I don't know if they're compatible

No, you can flatten it, just straighten the bend where the cable passes through

Hi Guys!

I am sure that I have put fw 2.75 on my chip since it came empty, but opening up picofly toolbox, it says fw 2.67.


Why?
Thank you!

I used the advanced V1 flexes from the first wave of the SX Core easily on all models, including OLED

Thank you guys since i have one hwfly v2 flex i didnt know it will be usable on v1 board, and youre right (soldering wire to the tiny caps was a little finicky but i succeded)

Now the console its booting the cfw again, thanks!

The most time consuming part of the entire process. Whew.

hi. i just installed the modchip i bought on ali. but it seems to be dead?? it always launches into the rp2040 bootloader. when i flash it, it mounts it self seconds later as a drive again. and the led istn blinking. any ideas?

we do not support the clone chips in this thread. if you want help here, get an rp2040-zero or rp2040-tiny

I've tinned the flex, but no luck.
Do you know which pins communicate with the board?? So I could measure them and see if they're connected

Post automatically merged: Dec 31, 2023

I've measured from end to end (point A to B). All pins got connection with the proper output pins and no short with neighbors.
Pin 4 and 5 (counting from top to bottom on point A) got reduced to just 1 pin on point B, other than that I don't see anything weird.

It's also possible that I knocked off some components, when I turned on the board. Now I have no clue where to look for error I also jiggled the joycon a lil bit, but nothing happens.
Pin 10 and 5 on point B (counting from right to left got 1,8V).

I've also measured the caps on the back of the port, they're good.



Edit: The right joycon gets juice from the switch, but only Bluetooth communication works... It's not being detected as "attached"

Describe how you flash it, do you press and hold boot button before you plug in the usb in the computer?

For the first time with me, a device with nand skhynix did not work with the 100/100/47 ohm resistor configuration. When trying the device several times I found the error "=***" emmc int failure. Upon checking all the points, I realized that the measurements were correct. I decided to replace the 100ohm resistor on the CMD line with a 47ohm one and the problem was solved.
