Hacking Hardware Picofly - a HWFLY switch modchip

[Dee87]

Would this modchip belong to this thread?

If so, I'll ask mods to move one post of mine to here...

nope not really , i still dont understand why there isnt a Thread for the HwflyModchips , i mean sure its almost the same and uses the The Firmware From Rehius but all these people having issue with them it would just be easier for them to create there own thred and not overrun the Picofly Thread

This is it... how do we repay him?

Paying him would make him a potential legal target for nintendo, so I think everyone is better off if we stick to saying thanks, think about him instead of our gf/wife, pray to him, name our first born after him, etc

Yeah thats what i was about to say i already asked him the same but its a high risk for him.

Had a Switch on 2.74 but occasionally boots to OFW. Just rolled it back to 2.73. All should be good now )

2.74 is depreciated cause it has issues with some rp2040 why would u still be using it ?

 

[Danook28]

clk is a tad low and b should be around 2.9v

0 read meaning short some where. About clk read about how much volt dieod mode???

It was a long-time done Switch, it was returned for OFW booting, figured I'd roll it back.

ah okay well, u should just be able to do a rollback never done it so couldnt really tell u how Xd

What does one yellow pulse mean after glitching? This switch sometimes goes into hekate and sometimes to ofw.

one yellow glitch means succes
if u have 3 pulses u need to tell if its long long short or short long short or what ever urs is doing.

here is the code list Xd

= is long pulse, * is short pulse:

= USB flashing done

** RST is not connected
*= CMD is not connected
=* D0 is not connected
== CLK is not connected

=** eMMC init failure during glitch process
=*= CPU never reach BCT check, should not happen
==* CPU always reach BCT check (no glitch reaction, check mosfet)
=== Glitch attempt limit reached, cannot glitch

=*** eMMC init failure
=**= eMMC write failure - comparison failed
=*=* eMMC write failure - write failed
=*== eMMC test failure - read failed
==** eMMC read failed during firmware update
==*= BCT copy failed - write failure
===* BCT copy failed - comparison failure
==== BCT copy failed - read failure

what firmware do u have ?

if i remember correct if u solder eather another 47ohm resistor or replace the 47 ohm resistor with a 100ohm to Dat0 and cmd ur issue should be solved

Greetings, I made my first oled with the new method of soldering the mosfet but the picofly turns on gives a yellow light and starts in original, the picofly is in fw 2.67. Any idea what is wrong?

What's the code?
Probally ==*
Check cpu pin wiring/MOSFET wiring

I don’t know what I test with my tester so I’m kinda lost right now. Does anyone know where I can find this on a Donna board it’s the clk highlighted in red. or can someone post a link I have a switch light that I use for parts

I just used the update.bin file and chose rollback on toolbox, got me to 2.73 instantly. Thanks @rehius
Gotta say feels pretty stable now.

I get this in Dat0 not connected and Poor mosfet wiring. Check the colors

Hi, can you guys answer me an doubt.

Installed an hwfly picofly instinct v1, all fine, is working.

But in the end of the install it is required cut the aluminium backplate where the chip will stay or the pressure is not an problem? Already trimmed the backplate in the part of the flat pass the hole.

Second time more precise

what tool you use for that?

4.7k ohms. there are a few on top side around the nand points on the top of the v1 and v2s.

here is on from the lite

Learn how-tos on kicad, reverse engineer the green adapter.
I've just order 5pcs (without ball) on jlcpcb for total $3.9 (with shipping).
Now i am gonna wait, what will happened next. First time using kicad and jlcpcb.

Here for someone want to play around.
