Hacking Hardware Picofly - a HWFLY switch modchip

[sq_mys]

You can convert it to bin with picotool and decompile the bin with ghidra, there is info on page 30-70

Does converting it to bin with uf2conv work aswell?

not sure what's the problem here

With the help of @lightninjay, I had a custom background made just for @binkinator

 

[Adran_Marit]

an idea/suggestion for @rehius: maybe add some info on how to boot into ofw on the "no sd card" screen?

press volume buttons

You are kind of missing the point here

No. "slow eMMC mode" = eMMC lines interference.

might be caused by not cleaned flux, bad soldering, lack of resistors, too long wires

Thank you, but emmc is completely abnormal and can't enter OFW.

It's kinda something that's been known since like hwfly or even sxcore if I'm remembering right.

Still missing the point. The random person finding my switch in the attic in 10 years might think it's broken or missing something because it's not obvious what to do on that screen.

Thanks. Fixed it. Mosfet was not wired correcly

I think it's a 'lost in translation' thing. I believe they meant to ask:

Does anyone know how to edit the SD Loader screen to also say "Press Vol- & + together for OFW"?

Now that I read it ^that way, the question makes sense and I actually like the idea.

How to set up this?

On the SD card, put "background.bmp" into bootloader\res\. If you use one of the ones we posted in this thread (@Dee87 came up with the idea, @lightninjay and I just expanded upon it), you're going to need to rename it.

That does make more sense, maybe @rehius can edit it in?

Finally got Custom made flex cables for the modchips now

Where did you get this from? I would like to get an OLED switch soon

 

[MrNatto]

Another switch lite successfully picofly’d

 

[POPOLO]

not sure what's the problem here

Boot directly display LOGO is MOSFET does not work
MOSFET please check

Very nice are u gonna release the files for us ?
would be much appriciated

 

[JackMaMa]

Yes, but so far only engineering samples

I'm not quite sure if they work

can send me project files? thx.
