Hacking Hardware Picofly - a HWFLY switch modchip

Sure I can. Just tell me how.

It's a mechanic.

Just dip the probe to the flux, for example around 1 cm apart, and read the ohm's measurement.

I got 30M ohms, don't know if I did it correctly.
What is a good ohms value for a flux?

thats not really good

it should be 0 , like my kingbo is 0

My flux is 0.

The ideal is, there should be no value shows.
Means the resistance > 99Mohms.

I just tried mine from 1 cm to 0.5mm, shows no value.

I was told kingbo is great. Is this the one you're using?

I use the most cheap one. Still waiting until this empty, then gonna try another different cheap flux

Guys. I am in a serious situation. I have a Switch V1 and i want it to mod chipped. I sent my switch to someone who know how to fix / install picofly but today he sent me a picture

showing the error 2002-3539 with the remarks that the health of the sysnad is critical so it is giving this error. Also told me that emunand is working fine but sysnand is not working properly. Whats should i do??

jupp thats the one

How many did u buy and what did u pay for I would like to get 1 or 2 off of u to see what the issue is with them

"Normally"
They should also work

Bought 5 and including delivery and tax cost $30.

he needs to use 100 ohm resistors for dat0+cmd. or add another 47 ohm for a total of 94 ohm.

 

[CarlosCruz]

Another permanent dat0 drilling method.

[linuxares]

Any reason why you moved the dat0 backwards instead directly to the chip?

Better change focus. What I do is enable a test point as dat0 and I get a resistant point where to weld and it is resistant to pulling.

Oh I see!

Update on OLED - I had a V2 with a normal rp2040 and swapped that out and put it on the oled and the oled tiny rp2040 into the v2. The v2 trained and glitched instantly (like normal). The OLED however, also gave the same =*== code and boots into ofw. So i definitley did something wrong. I reballed fine (by hand). That all went smooth. The only thing i can think of is the clk resistor. Because I did knock it when exposing the clk point. Not sure if got damaged but it gave a reading of 666ohms. Anyone know what reading it should be? Thinking of replacing that, maybe that resistor is damaged internally and not allowing the emmc check to go through and read? Not sure, any ideas? Atleast the tinys are legit, so theres that. yay. but the oled is still booting into ofw. noooooo.

clk resistor? u mean the resistor next to the clk ?


if u mean the resistor next to clk line then its 100ohm

I dont think there is any CLK resistor unless you talking about this 100 ohm one next to the CLK trace

yep sorry, i meant the resistor near the clk point. So I tried measuring it but it wouldn't settle on a value. Set my dmm to 200hm mode and it shows readings of 45ohm. Then taking my probe on and off it would show 167ohm. sometimes 115ohm and then 87ohm. But never settles and just flashes these readings not staying on screen. Not sure whats going on here. I just hope it isn't a trace repair job. then im screwed. If it is this resistor, then i can change it no probs. Any idea on if its this resistor or not guys?
Also whats the function of that resistor? Linked to what exactly?

Check ur batteries from ur dmm if it fluctuates so much.

Otherwise change it with a 100ohm resistor then ull see if it works.
Check if u ripped a trace ifso try to fix.

No clue what its for sorry.
