Hacking Hardware Picofly - a HWFLY switch modchip

[iolo57]

yea. Im tested in windows.
Need install linux

yes it works well with ubuntu, I just tried with a rp2040 zero and I got the firmware "test.u2f" with this command:
sudo picotool save test.uf2

I used this tuto to install picotool correctly:

can you post the file (i can upload it to my server just send me a email with the firmware file to [email protected])

Hi.
RP2040 good work on 3.3v
And perfectly work via emmc & MicroSD card.

Im find firmware for rp2040, but dont know fow to dump it(
I have rp2040 with firmware and need dump it

Yes, of course the guy with the stockphoto profile pic who joined TODAY
has the only working ... whatever it is supposed to be
totally legit
not a troll

lol, find this photo...
im really, picofly its work

 

[linuxares]

Well, give me the sha256 of it and I can ask someone to verify it

Can find it on a few Russian websites.

Also, no to the thing you said. You're clearly a troll and no good will come from this.

You're 13 years old. Stop falling for internet trolls and ffs stop using your real name and posting your private email address

he could also post a photo 🤔

 

[linuxares]

My sources say, yeah. He doesn't have the "pikofly" code.

 

[SylverReZ]

Of course they wouldn't.

Well the rumour at the moment is that the author has sold the code to a company in china and funnily enough the China factories are ramping up production of the actual 2040 ic.
If this is true its possible we can still make our own. We will see

This is a total departure from the initial “mission statement” of “screw HWFLY and their price gouging”.

I have a theory about this.

My theory is that the "picofly" was never a full jailbreak in itself - it could only perform the voltage glitch after the timing parameters are found with "training" from the hwfly.

The benefit to end users in that case would be very little. Instead it would be modders reaping the benefits who would no longer have to buy an hwfly to install in every system. They could use the same hwfly to find the timing parameters, and then swap in the $2 chip and send it out the door.

If this is indeed true then it makes perfect sense why this is being held back. It would create a lot of confusion between modders and buyers about pricing and potentially there would be a backlash against them. Also if the timing parameters ever changed then it would be impossible to "re-train" without hwfly and warranty would be a giant headache for modders.

Again it's just a theory and I don't have any way to substantiate this.

Occam’s razor says the Ninty Ninja’s found out and simply told them No.

Nothing to back it up but until we get a direct explanation from those involved, the simplest explanation is the most likely.

 

[ConsoleKid69]

Even if ninty said no their would be nothing stopping them selling the code on. But hey what do I know lol...

It would be nice if a new chip does show as it will stir the market up and get the prices down to a sensible level and as said before if its using the 2040 it can can ripped easily and im sure somebody else in the scene with balls will do something with it.

when it detects the custom BCT / bootloader isn't installed

Actually I don't think it does this at all, although it SHOULD (if possible). Thus, people black-screen after updating firmware in OFW (which overwrites boot0/1, overwriting the chip's payload). It doesn't try to detect it, if it has already been trained. One has to reset the chip and retrain for their switch to work again, in this case.

Maybe the original news about the new $3 modchip was just misunderstood?
Maybe it meant that the new modchip would cost $3 more than the HWFLY? Or vice versa, $3 cheaper...

I've only updated (sysNAND) OFW a handful of times with the chip install but I've never had that happen to me. It always reflashes the bootloader and then retrains. That's with both an official SX Core and a HWFly chip.
