Hacking Hardware Picofly - a HWFLY switch modchip

[LogicalMadness]

Wish I see less switch send in due to self mod failed

I've got an alert set on my local selling app (OfferUp) for "broken OLED".

Never see any Switchs, but one day I'll swoop on a broken OLED to fix XD

Hey guys... Will these work? Just received it. Waiting for the RP2040-Zero to be delivered now.

My local marketplace sucks, wish to see your swoop happen here as well

Hello. Raspberry Pi PICO user here. Getting green color after flashing. I was going to ask how to set RGB mode on RRPICO but I remembered the LED light will be removed anyways. Is this correct, or am I missing something? The only thing I did so far was soldering the detection pins. Waiting for confirmation if I need anything else before I begin. Thanks!

you dont have rgb led on the RPi pico. So good to go after uf2 flashed

Thanks. I needed to hear that. 2.65v flashed. Off I go.

If the soldering is correct, and you get 0 Ohm (test on the lowest range of your multimeter), the trasistor is defective (Drain and Source are shorted). If you remove the wires from the MOSFET, what's the resistance on the Capacitors?

I use the new mos tube and Pr2040, and it works fine. However, the temperature of the CPU is still high, and the resistance at both ends of the cap is reduced to 2 ohms after startup.

Where is the switch damaged or is there a solution to this problem?

Just to show how much I believe the statement that picofly works on ALL firmware versions, I updated to 16.0.2 on OFW, booted to Hekate, dumped keys (there's one new Dev.key one called "secure_boot_key" btw), then dumped OFW with tegraexplorer and updated CFW with daybreak. CFW emuNAND still boots just fine.

Have you tried 'Warmboot Error Fix' to boot to ofw?

your picofly version?

Currently still running 2.64 like the definitive guide says, but I'm sure 2.65 would be equally fine.

i already try on my pico v2.5 all cfw and ofw working fine

2.5, or 2.65?

2.5, or 2.65?

2.5 my dear

 

[lightninjay]

2.5 my dear

Interesting, as long as it's stable I suppose no need to upgrade!

If the usb still there, use 2.65 is better. fw2.5 cannot update.
Update mechanism (without usb) only exist on >=2.61

thank you for your advice

Maybe the RST line need cleans. I remember @rehius saying that RST line is sensitive.
And i see in the pio glitch, it kind of make the cpu in reset state, before glitching.

I think the fuse is inside the tegra, in the range of nanometer, can't be seen.

but It glitched successful without sd card or empty sd card

They should work, yes, just bigger than 0805
