Hacking Hardware Picofly - a HWFLY switch modchip

[k28]

Ok try the above. Might be another Mainboard issue though.

 

[superxoi]

Yeah my burn fuse is 19 so the one i can do is 17.0+ . i did every step sthetix showed on youtube but the switch just flashing nintendo logo then shut off. Don't know what to do next. I bought the mainboard which emmc being damaged already so banning have no effect on it anyway.

You are my lifesaver friend. I launched sysmmc cfw and the switch pass the nintendo logo now. I have been putting this one in the closet for a month now .
Edit : now it can enter ofw too. Wonderful.

Picofly FW 2.76 long short long short

Picofly 2.76

 

[abal1000x]

Picofly does not glitch with rebuild nand(original prodinfo present) but boots into ofw.

Error code:

Picofly FW 2.75 short long short
Picofly FW 2.76 long short long short


-The installed picofly glitch to hekate with corrupt nand.
-The picofly glitch to hekate with empty emmc.
-The picofly(including same flex) glitches fine in another switch where the original nand is present.

-NOT SURE: i might be remembering wrong but the picofly glitches to hekate with rebuild nand WITHOUT original prodinfo present.

I use @sthetix tutorial. I asked him what the issue could be but he unfortunately told me, that he doesn't use picofly.

Do you guys think that this is fixable by FW update for picofly?

If i take a guess its oled right?
I am pretty sure you use dat0 flex right?

Your emmc connection installation are not stable enough. dat0/cmd/clk.

short long short while you could boots into ofw means the cmd (or clk) line to the picofly is problematic.
Since picofly read the initialization of the emmc by sniffing from cmd line.

long short long short means cant write its mainly the dat0 problem, the line to send the bytes to write.
At this point the emmc init are detected so cmd/clk is okay.

It‘s 47k

You sure that it's 47k?? I'm struggling to find one on switch lite board

 

[BlueBeans]

Maybe you guys can help me out on this one. Pulled a donor emmc because I had destroyed the original. Restored the backup that I had made

Does anyone know the value of the resistor near the cmd one??
Switch OLED

4.7kohm

4 mosfets for 1 device(3 failed). i have a bad batch now.

 

[nclabz86]

Do you know if switch lite board has one?? If yes, where??
I got a defective switch lite board, so I can harvest it from there

if u have

4 mosfets for 1 device(3 failed). i have a bad batch now.

Try add scl and sdat line
Its working on me

He means the resistance next to it and that is 47k

So here we go, the proof again:

It's V1 unpatched/patched and Mariko. Always same behavior with rebuild nand.

So you mean its happened on all variant, when rebuild nand?

Lol, I got the same multimeter

Now I'll have to find it pn my spare boards

Yes. I didn't tried with lite and OLED though.

Or order some from AliExpress. It may take a little longer, but you can order a larger quantity straight away.

I'm having a strange issue- the glitch consistently works with the apu shield up, and consistently doesn't with the apu shield down. Any clue what could be happening? (I've attached some pictures of the install, those are the best I can get without desoldering connections.

It’s not obvious to you when you look at your own pictures?

Holy cow what a mess….. clean everything up and redo the paste. Look for some guides how much to apply and to where, and where not to have cooling paste.

Every time I've opened one up, it's looked like that so I just wanted to leave it like I found it. I can clean up the paste but I'm almost certain it's non-conductive and if that was the problem, I would think it wouldn't work at all.

That's my second plan, I promised the guy that by tomorrow it'll be done... From ali it takes forever to deliver.

Found on eBay for 2€/50 piece, I'll get them Monday or Tuesday, I hope the owner of the switch won't start whining

Is it a guinea worm? is it a spider's nest? is it cordyceps? I'm traumatized


...to be a bit more constructive, you've stripped the insulation off of your wires in several places, and whenever you close the shield it will connect with the uninsulated wire parts and short your mosfet wires to ground.
I'm attaching a pic of one of my installs, for reference
