Hacking Hardware Picofly - a HWFLY switch modchip

[FreeLander]

Hello,
How's everyone doing?
For the first time I got a Toshiba OLED, Installed Picofly normally but I'm getting all sorts of mixed up errors and purple screens. Checked all wires and CMD is giving 4.7ko.

I'm reading old posts that Picofly is having issues with Toshiba, has this been fixed in the newst firmware? Also, Toshiba is not listed in AOI OLED compatible with Picofly. I'd love to know the current status on Picofly installed on Toshina OLEDs. Thanks!

I had just installed a picofly on a mariko model, and the right joycon does not want to connect. i am on the startup menu so i cant get past that without connecing both joycons.

I tried joycons i knew that worked and i even tried swapping the rail. no dice.

I feel like i saw a video on fixing this somewhere, but i couldn't find it.

If anyone can help, please let me know!

Have done several Toshiba ones no issue there. In terms of firmware I go with the bare minimum.

As a soldering newbie, I'm very scared to try and do this job myself!

Known issue with these ribbon connectors. You need to add strip of kapton tap at the back of the flex in order to make proper connection to the pins. I actually had one several days ago.

Does anyone know about the 3540 error on OFW?I also tried on sysnand with cfw enabled and instead of the error my game freezes.on emunand games work ok.I would appreciate any help

Thanks, Are you using the latest 2.75fw?

 

[Crafty_The_Fox]

thank you, this is exactly what i saw i think.

So I think mine is gone if I have no backups of anything. Could it also be the Picofly firmware that f upd the mainboard?

I got a new switch lite should I use the same HWFLY Lite RP2040 again? It glitched fine to the Picofly screen. I’m a bit scared of using it again… but I don’t want to buy a new one because it takes so long to arrive. Also is the new Picofly firmware good 2.75? Or should I use the 2.73?

Use the latest Picofly Firmware from here and after booting into Hekate save *first* your Biskeys (Lockpic) and do a nand backup.

need extra resistors on dat0/cmd, same as usual, should be 100 ohm total, not 47

I have a similar problem on a V2. 3539 error in OFW. Game freezes in CFW sometimes, and then im unable to boot OFW.
I have 2x 47 resistors

What firmware version do you use?

If its easy for you to update the firmware, try the latest firmware available (2.75)

Theres issue on powering down the picofly, that has been fixed.

Or you could try my custom firmware, i have different opinion on the picofly sram power down mechanism. Might be correct, might be not. Risk on your own.

what is the risk? software or hardware? Where can i find 2.75? On rehius github? Will 2.75 also work on rp 2040 board zero since its the same chip?

Di you know how I can check my resistors without opening my switch?I mean is there any software for this?
