Hacking Hardware Picofly - a HWFLY switch modchip

[3CP-andres-N]

colleagues, the chip turns blue and turns red, start the original console, how could it be solved, thanks for the help

ensure the LED is properly configured (red when you write .uf2)

if LED is fine, check eMMC connection (looks like purple light actually)

So is anyone selling all the needed parts in one? If not, which sellers are recommended?

They're all basic electronics parts, nothing special. Ebay, amazon, maker shop around the corner all should have this stuff.

boa tarde a todos , alguém tem algum tutorial de como progamo a rp2040 ? parece uma pergunta leiga mas nunca utilizei ela

English please.

srry for the offtopic post does anyone here have experience with reballing emmc?

is this solder paste okay? klick me for link

Looking into parts. Would this resistor work fine, size-wise, for a Switch Lite? The AIO thread suggests an SMD 8050 resistor size but I can't seem to find that anywhere.

Also, would I need to update the firmware on the RP2040? If so, how would I do that? The USB port will be removed, so I'm a little stumped in this area. Would it be better to get an RP2040-One to simplify this?

sure they would work but instead of looking for 8050 might wanna search for 0805 :-)

I would prefer SMD resitor size 0805, 1% tolerance (i guess you got the number wrong).

yes

 

[Dee87]

yes

nice just orderd it so i can reball the oled emmc and set a permanent dat 0 pin

but befor i do that i will try first on some defektive emmcs and then try one extra thats works before i go the the oled :-)

The AIO thread says 8050, so that's what I searched:

• SMD 8050 47 to 50 ohm Resistors

Probably worth an edit to prevent future confusion.

Either way, thank you! Found this listing.

Another question: what is the reason for removing the 3.3V regulator from the RP2040? If I'm to update the firmware later, wouldn't I need this?

although @rehius said it is ok, i think that a melting point of 138°C is a bit low for this kind of chip also considering how tight things are packed inside switch (and the temperature levels inside).
Anyway, i'm in way an expert on the matter but I thought it was worth giving it a second look.

@Adran_Marit

can u change 8050 smd to 0805 please thank u

Either way, thank you! Found this listing.

that one looks better

to save some space , yes if u want to over usb u should leave it

i think when fw 2.6 is released u can do that over hekate so for now leave it till the update is out

 

[FlitPix]

i think afte fw 2.6 is released u cn do that over hekate so for now leave it till the update is out

Ah, I'll be able to update using the SD card? That works perfectly then. I'll leave it until I know for sure, thank you!

Guys this error means I need unlock or is something else?

what firmware did u flash ?

i had the same issue

flash the firmware from https://github.com/Ansem-SoD/Picofly/tree/main/Firmwares
first flash 2.5nw.uf2 then flash unlock uf2

what atmosphere version did u try ?

although @rehius said it is ok, i think that a melting point of 138°C is a bit low for this kind of chip also considering how tight things are packed inside switch (and the temperature levels inside).

With such melting point it's much easier to solder eMMC back, no damage due to overheating, less PCB bend.

Commonly such high temperature is unreachable (I highly doubt you can get your eMMC even up to the 60°C).

Can you list the needed parts please?

You can find everything in the AIO thread.
