Hacking Hardware Picofly - a HWFLY switch modchip

[SylverReZ]

thats right
but one more question
do i need to desolder the nand on a oled switch for the hwfly instalation

You just slip the adapter in whilst heating up the eMMC chip with a heat gun. Installing it is very tedious and you can slip up even with the unsteadiest hand.

Its dead.

Its dead.

Sucks to be right.

Ehhhh. From what I heard, these things were damaging consoles. Even if it released, I would have ordered a hwfly regardless

I won the bet, but it's sad

Exactly!

I won, but I lost.

very sad i wish there will be some other guy some day that is super expirienced egnuth to make something like this and post it on github

I mean, at this point with how cheap the latest hwflys are. You're better off just getting one of those. The reports of why this was delayed at the start was due to them randomly bricking consoles. I wouldn't recommend anyone put those damn things in their consoles

lol how could you hear that when officially only two are known to exist? Either way doesn't matter now.

i think they break consoles is because these are 3.3V chips and the emmc/soc are 1.8V devices so a simple level shifter is could help that situation so the rp2040 costs 3$ and the level shifter 1$ the pcb 2$ (10 pcs from jlcpcb) and that would make the cost 6$ i think after shipping and assembling from jlcpcb it will be arround 15 to 20$

I might be wrong but I don't think that when you drive the NAND you're sending 1.8v to it. My understanding is you send it 1.8v on the powerline to run it, but when you're sending and receiving data you send it over the TX and RX lines which run at only a few millivolts. Sending 3.3v to a pin expecting only millivolts would instantly fry whatever peripheral it was connected to so it wouldn't be random chance or a waiting game. Either it would or it wouldn't.
Since the chip wouldn't be providing power to either the SoC or the eMMC having them run at different voltage levels wouldn't matter at all if I am correct (in fact, the chip would be syphoning power from the eMMC power line like currently available chips rather than adding power to it).

what partnumber has the switch/switch oled emmc

 

[FruithatMods]

The EMMC chips used in the switch are compatible with 3v3 power rails according to the specs.

and is the tegra x1 soc also 3.3 volt compatible

 

[r1vver]

I was thinking, since we all already bought those useless Zeros, let's buy ourselves some Tegras too and start feeding 3.3 volts from Zeros to Tegras.
We'll have a flash mob of sorts. At least we'll have something to do...

Here you can reed why 3,3V not working whit a soldered emmc.

Well, I think I will make a old PC joystick DB15 to USB adapter!

@evil_santa I know you are just trying to be helpful but what you are saying isn't true.
You need to check the specs of the specific nand chip. You have linked to research about a completely different device. Many nand chips will happily support 3v3, and even in some cases where they are only documented to work at 1v8.

The specs are listed above. Please read the previous posts before jumping to conclusions.

No you didn't read the link I send.
I'm tinkering whit emmc's since 3 year's.
Dumping a soldered emmc isn't possible whit 3v3 logic level. unsoldered yes.
It's the same her you can't interact whit the emmc if he is soldered to the bord.
