Hacking Hardware Picofly - a HWFLY switch modchip

[FreeLander]

Hello @FreeLander, looks like you found the dangerous incorrect diagram by sthetix where the 3.3v point is actually direct 4.2v right from the battery. Be careful, such overvoltage may fry your RP Pico and the console. Please use the proper 3.3v point here:

Hello. Thanks for getting back to me. Yes, I made the mistake of wiring the 3.3v to the cap shown in red, then changed it to the correct one you pointed out. I'm still getting a single green led then nothing. Console is still booting normally without the modchip, thankfully. Here's my soldering. Would love to hear if you spot something wrong

latest firmware is 2.65

Yes, sorry. 2.65 downloaded directly from Github

Here is D0 point, looks like you did it wrong

Is this the right one? I feel like it’s hard to find it in Germany

Hope y’all can open the links

Not hard at all, use Amazon there is a set with a few different resistors with 47ohm costs 7€ next day delivery

Thank you so very much.
It worked.


I love this guy.

WHAT COULD BE THE ISSUE?

Hello asking for help, OLED switch is hard to turn on(NOT GUARANTEED ONE TAP POWER BUTTON), or randomly turns on when I tap/hold power button WHEN ONLY TOTAL SHUTDOWN. I did this after picofly and removed EVERYTHING. When it turns on , buttons and chargers all work no issue except for missing charging icon on top left when docked.

May I ask for help?

Voultar is an experienced modder. Here he is installing the MOSFETs on a Lite. He does a really nice job with it. Other pics from his install are on his feed.

Fuck, that video was loud. Still, he's recently made a eMMC replacement for the Wii U.

These buttons are hella sensitive. I had to clean mine with ipa and reseat them

Does it help the WiiU from being a complete POS?

Is it ok or any effect if I solder the CMD point to the left side of this resistor and the 3.3V point as shown on switch lite?

POS, dunno what that means. But yes, its a perfect solution to recovering bricked Wii Us.

RP PICO is such a headache. It worked fine but when I cut it, it no longer boots.
Stick with rp2040, people.

Did you cut according ti the diagram?

You cut it too much, pin 20 should be partially present, look at my example in the main post (page 78)

The buttons ribbon cable end(the on you press) or the point where you combine it with the motherboard

i installed a picofly in my v2 Switch and it works perfectly fine.
After updating OFW from 15.0 to 16.0 i just got a black screen.
(i did this using the official updater).

it doesnt boot at all (no logo etc) but cfw still works on the newest.
After checking fuses it was showing 17 (which means v 15.X) but it should be 18 (v 16.X)
how do i allow my switch to burn a fuse and access ofw? i was using daybreak to downgrade to 15.x and ofw works again...
So.... anyone know how to disable the "fuse burn blocker"?
i use picofly just for homebrew and play all my legit games by card. emunand does work too but i d like ofw to be up to date

on boot hold vol + and - and boot into ofw, after that update firmware

i will try that - thanks in advance

Hi guys, I'm lurking the thread from the very firsts pages, you're awesome. I've finally gathered the courage to try modding my v2. But trying soldering the RST I've accidentally removed the two tiny cap. I can't find informations about those cap and they are really difficult to replace. What should I do?

Up. Anyone know if I have to replace the caps and if i can use the pi-zero`s one.

My latest install with Helder's expansion board. Using a ground near the USBView attachment 366717

where are you getting the 3.3v from???
