Hacking Hardware Picofly - a HWFLY switch modchip

[abal1000x]

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.

What version the picofy fw you use?

What version the picofy fw you use?

In this case, i try 2.75 and 2.76.

Why you use 100 ohm on dat0??

From where did you got 2.76?? Official firmware is still 2.75

Because thats the ”standard” nowdays that works 99% of the times perfectly. 100/100/47.

does this mod chip work i can only or on amazon i have a mariko switch

this is an English speaking forum, sorry

kamikaze time...i have spare time to tinker so i did what i can to do a OLED kamikaze mod ( DAT0 )....patiently diggin cleaning and hard work paid off....

Congratulations on your success. I'll probably continue to rebuild it with NAND adapters.

In the end it has to work.

I just tried kamikaze again. This time patiently doing the grinding. The 0.2mm tip was good at this method. My first attemp of kamikaze was I almost cut the CMD line. Now I am more confident to do all these on my future OLED modding. No more removal of the board.

How much time would you say it takes to do the dat0 point this way? from start to finish, so to speak

Help identify the component and its value. switch rev.1 mosfet burned out and took it with me

about 10min from grinding to solder jumper wire on the dat0

Hello, if I use the i2c undervoltage hack, which lines on the RP2040 are not needed?

Hi, sorry for my English, but could someone help me, I installed the picofly chip in the OLED switch, but there are times when it causes the glitch, and there are times when it doesn't perform the glitch, so I try again, and it it works.
but when it doesn't work, it gives the sequence of yellow blinks as follows: *==.
a short one and then two long ones, and it enters the OFW.
Would anyone have any idea what it would be?
Note: EMMC value is correct

It is rather strange problem that I encountered two or three times. Will you try to format OFW. It worked for me when there is too much data from previous owner of the console.

i had this one shorted once. i had to find another dead board for it. if you didn't replace it your switch would not turn on. there are no store in aliexpress selling it. the only source you can is trying to find a donor board(v1) for it.

replace dat0 resistor on rp2040 with 100 ohm

Hello just got my modded siwtch back and wondering if there is a way to transfer all of my emummc to my new switch, without having to re partition everything and back it up.
EDIT: Forgot to add this since the OLED is 64 partition would that create issues if my previous backup was based on a 32gb partition

I'm trained to solder the mod but I need some more info that I can't find anywhere.

Hi guys, I'm training myself on soldering, and I think I can finally trained to solder the picofly it's just 4 solder I can make it with calm and some relaxing ambient sound in my ears...

But there are something that I can't find anywhere:

1. do you solder some tin on the flat that goes on the cpu, or you just advice me to put some flux and solder directly?
2. what gauge do you advice me to use for the solder wire?
3. is there any centralized website like for the 3ds/wii era where I can find anything about this mod?
4. Someone on yt advice to not cut the aluminium cover to better sit the picofly because it's needed for better airflow. is that true? Is there some video or pics that show how to place the picofly without cut the cover?

Thank you in advance to everyone would help me a bit, and wish me good luck

1. do you solder some tin on the flat that goes on the cpu, or you just advice me to put some flux and solder directly?

No need of pre-tinning, just sit the flex, apply flux and solder.

2. what gauge do you advice me to use for the solder wire?

36AWG for data wires, I prefer 30AWG for power (GND + 3.3V). Solder wire, just use some 63/37 SN/PB wire (edit: 0.5mm in diameter or lower is more than enough).

3. is there any centralized website like for the 3ds/wii era where I can find anything about this mod?

You're in the right place. Just read @lightninjay signature before soldering, you can find there a lot of useful info.

4. Someone on yt advice to not cut the aluminium cover to better sit the picofly because it's needed for better airflow. is that true? Is there some video or pics that show how to place the picofly without cut the cover?

Forget YT. For OLED and Lite there's no need to cut the shield (chip for OLED goes on the right side of SoC cover and for Lite on top of eMMC cover). For V1/V2, if you don't want to place it on top of the shield, you should cut it since there isn't much clearing space.
Ciao!
