Hacking Hardware Picofly - a HWFLY switch modchip

[sergiochendry]

hello
do you think solder wick can absorb the lead solder on the RP2040 zero 4 leg ??
im having trouble remove the leg
View attachment 373592

im planning buy solder wick...
but kinda hesitate if it doesnt work, if the wick cant absorb it
View attachment 373593

mix with low melt solder tin
make easier gootwick to absord it

Hello
1) I would like to thank you for the great amount of perfect work that has been put into this project! good work !

2) I have switch classic, maybe it will be V2? (PCB: had-cpu-01) where I don't have the original nand chip .. is it possible to use picofly even with a nand bought on ebay to regenerate the system? or picofly does not boot(hekate) if the switch is not functional (now of course it will not run.. without the correct SW in NAND)

sorry english is not mi native language

yes but u need to rebuild the nand from scratch there are some guids in the forum use the search function :-)

u will be able to boot into hekate and use ofw and cfw but you will never be able to use the online service if u rebuild the nand withouth the original keys afaik

Give it a proper clean and inspect it. If the trace is broken, it must be fix. There are two methods you can add a solder to see if it connects the both. But not recommend without proper skill.

Second Method which I personally prefer is that you should use a 0.1mm and connect the paths.

There is a point on board. You have to grind up the board to add a Dat0 point. Right Now, I don't have a pic. But you can find it online. If I find I'll edit this post.

Because of these cheap one dat0 adapter, We can damage our emmc chip or may be corrupt it. See @QuiTim Post below for a nice quality adapter.

I'm eager to know the two methods. What are they?

Thank you for the information! yes, I know, I've already done it on another switch using RCM payload (on this one, I activate the RCM mod, but I can't send the payload - probably a patched version) - I just didn't know if picofly would also boot on switches where there is nand from another switch from ebay

Hello. which one of these is point A and which is point D?

yeah if payloads dont work they are patched.

install pico ad emmc end then it will boot :-)

Emmc Pinout

hope that helps u

remember if u cannot reconnect the original clk via u need to connect the clk line from emmc to the line that goes to the apu also

middle one should be cmd the left one should be clk

Hello, I just installed a picofly on a mariko switch, now I will try to install it on a Oled version.
Just two questions,

-can we have a easier alternative for the CLK point ? Maybe one the Emmc ? (Im not a pro)

And second question:
- I bought this on aliexpress for the DAT0 and 3.3v, it's a good solution ? Thanks for all !

 

[bilalhassan341]

nintendo switch lite, removed chip, working normal.
checked points all Ok not used diode mode to check.

used 0.1wire, after i used 2wires for data0, clk etc. gnd awg30 wire…. same

soldered sda and scl no lack. Never tries presing reset after screen show , you mean shortin 1-2pins on side?

on one chip removerd port and buttoms, other have all aprts

Check your wiring in diode mode. If still same issue try to flash a new firmware on new rp2040. Btw what your pico fly firmware is?

Try this: https://gbatemp.net/threads/picofly-aio-thread.628951/post-10166614

ive seen this vid

but im gonna try with
dee87 and sergiochendry method first
with adding low melt lead solder and absorb with solder wick


*last time i have use that video method, but i only heat on the 4 leg. im scared to ruin the front pin with many tiny resistor :V

- The "scraping" CLK near the SoC is the easiest method if you don't reball the eMMC with a green BGA adapter

- You just missed this few posta ago https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/post-10167138

Ditch that DAT0, it's not precise and you're risking to damage your NAND.

Which adaptor do you recommend?

Which adaptor do you recommend?

The one in the link by QuiTim or this:

How to solve this issue?

do he still recommend cutting it?

 

[Phantomas77]

do he still recommend cutting it?

The "OATO" one? I wouldn't even bother with that one, better to buy a decent adapter or a BGA153 stencil + hot air station.

and good afternoon bro, are you the owner of the forum? I can only write as many times as you want? If you are the owner of the forum let me know, I me will withdraw...

Rafael, it's common sense not to spam, come on...

Thank you. D and C are clear.is the one in the middle A?

I did a fun little project. V2 modded but with broken SD card slot. I manually soldered each connector to the motherboard and got into Hekate, I got this message although SD card info was shown correctly. It boots into main screen and SD card size is shown in data management.
