Hacking Hardware Picofly - a HWFLY switch modchip

[Akiira]

=== Glitch attempt limit reached, cannot glitch

The Picofly starts flashing blue, if the glitch does not occur within the minute it emits a long yellow flash and resumes flashing blue and within the minute it does not perform the glitch emits 3 long yellow flashes and starts the stock memory.
Definitely an installation error because in the end the stock has to start.

Another question, the problem is with the pico fly or with Hekate? Because it happened after I turned off the console in Hekate

Iam doing this PicoFly for first time on the Oled, On the 3.3v i shorted thing tiny ass... capacitor.
After trying to fix the short it came loose, tried for 2 hours tro get it back on with no suucces.
Is it a necessary cap or not?

i tried to turn it on this way, see picture.
All i get i a purple screen, is it becouse of the cpu flex still being on it or the resistor?

Poin A read 8.4k on multimeter, soo this one is find, its a 10k resistor as i know.
Does pruple screen appear if the modchip is not assembled completly?

Thank you, but what kind of flux please. The one i have now i becomes brow and sticky verry fast.

And solder wire, lead or no lead?

The problem is neither. The problem is purely hardware.

So it's bricked?

Pfff, is this good now?
Need soldering mask.

One tingy, power button does not work, it turns on when i plug in the power cable.
Glitching time 1 or 2 seconds.

I hope you plan on trimming those wires down. Length of your wires could be effecting the glitch as well.

Yes, happy it works.
Btw any solution on pwr

 

[thesjaakspoiler]

I dont think its the lcd connector,
Either Resistor, Point A or the tiny one i broke.
Or the Flex thats still on the cpu.
I will remove the flex on cpu to test out.
What a headache.

If you think the flex cable on the CPU is good then you can use it as-is.
No need to remove that.
Installation details can be found here :
https://gbatemp.net/threads/picofly-aio-thread.628951/

For wires, just use what you're comfortable with, just don't make them too long.
Solder comes in many forms, but nothing exotic is needed.
I can only get lead-free solder here.
Flux can be helpful but do clean up afterwards.

plz becarefull when use solder paste. some time it is move under chip and make so bad short.

Thank you,

In hekate i get the error
emmc is initialized in slow mode.
Rebooting in normal mode i get purple screen.

Diode tes on dat0, red on ground and black on dat0 i get 0.433
Volt Test 3.3V good
D 0.95V
A 1.81V
C 1.81V

Can it be the Dat0 adapter not in place?

I have not heated the nand.

---------------

Edit,

I have removed the nand adapter, desolderd the A, and D point.
Still purple screen.

it could be the resistor on A point.
What is the value of this one?
Some say 4.7k and some 10k.

Can someone please provide a Ali link for the correct one.

And

Does any life in Holland who does modding?

resistor A the correct value is 4.7k ohm

disconect battery and read resistor A point with multimeter it self from both side 4.7 k OHm

 

[taxco]

disconect battery and read resistor A point with multimeter it self from both side 4.7 k OHm

I did, i belive it read around 8 or 9k.
There is this chinese video saying 10k.
My switch comes from japan.

can someone orovide the link please of 4.7 0201, there are so many.
Thx

Is this the correct one?


Edit More info who will have same issue:

• SMD: Indicates it is a Surface-Mount Device.
• 0201: Refers to the physical size of the resistor (0.6mm × 0.3mm). This is a common size for components on modern electronics like the Switch.
• 4.7kΩ: The resistance value, which is correct for the CMD point resistor.
• 50mW: Maximum power dissipation, which is sufficient for this application.
• ±1%: Tolerance, meaning the actual resistance can vary by 1% from the stated value, which is acceptable for this use.

is it good to add new chip or need more wick. i can add 2k cam pic. this chip is 7780 ic

Flat pads always best, and the chip is called MAX77801

I have installed an RP2040 tiny on a switch lite. I removed the fpc connector and the voltage regulator but the shield plate was still touching the chip and I had to bend it a little.

Now I will mod another same console with the same chip and I might cut or drill the shield plate to make some clearance. Is there any better way or a better position for the RP2040 tiny?

After removing the fpc connector I’m not able to update the firmware. Should I leave it on? Are there any reason to update the RP2040 firmware in the future? Could it be needed to update to a newer atmosphere version?

this is the best place for lite to seat the modchip. Simply remove the foam and tape rp2040 down on the emmc bracket/shield

 

[snaker]

As jkyoho said this is the best place. No need to cut anything with this placement.
