Hacking Hardware Picofly - a HWFLY switch modchip

[frozenboy]

there are two kinds of LED: BGR and RGB, it is easier to use yellow/white/blue rather than ask people to swap colours with jumper

Almost all of my test units don't have heatsink, until you start a game it's fine

I am also a fan of green led for success. Looking green led make me feel relief that nothing wrong. It would be great if you get it back in next version. This is my silly idea but BGR and RGB only revert led B and R right. so green should be the same for both, Am I right. It still make me wonder since G and R be revert instead off B and R like the name it should.
I guess I will stick with lower fw version in the meantime. btw, Is that necessary to put resistor to the mosfet. I found it exist on the cable, but it seem some people put it in mosfet and soneone doent. And what is that purpose of it

I don't know about oscilloscope.

Is this good enough to be used to monitory the emmc line:

What is the specificaiton of scope/logic you use?

certainly not.

The most useful thing is DS Logic, I use the cheap one, but the USB 3.0 one is much better (but too expensive for me)

@Dee87 your pdf tut is great, but the pic of pinout for lite a little confuse with cmd and clk pinout, I make it wrong for once. If you could use another pic, it would be great. And the alternative pinout such as from emmc could also be useful. Some pin is quite easy to be bridge, especially from the power circuit could make a lot of trouble if it get bridge. I got my sw unable to boot up while trying to get 3.3v and gnd from those cap. and these cap is hard to unbridge once the tin got between them

This is not my PDF

To the bridging then use proper tools and not to much solder then u won't have that issue ;-)

I done that lot of time and its okay, nothing broke.

Just adding, pay attention to the fan if it start spinning then you must hurry turning off the switch. If it not spinning yet you can even go to hos home, no issue whatsoever. Ive done these just to test that ofw still function properly after mod, and if some error happen i can easily check and fix without opening anything.

Hi how i can test voltages of my sd reader from v2, i accidentally destroyed the flex of first 1 bought 1 new and still the no sd detected msg

 

[detilmalala]

people, from what I understand, even if the nand of the switch is bricked, you could start atmosphere with the pico in place, or am I wrong

Add pic for help.

if the nand broke, where the cpu will fetch the program to be loaded into ram?

Emummc is part of nintendo switch nand that can pico boot to it normal...!!!!

CMIIW.
The first thing the cpu do is load the code from nand to ram, and run the code.
So thats why we inject the sd loader to the nand, so we could use the emmc, then run some code from the emmc, and the party is on. Like hekate, atmosphere, payload, homebrew, etc.

I can soldring pico to my unpatched nintendo switch v1 that load from hekate to Atmosphere black secreen me be it well boot to cfw emummc and work!!!!

I have an unpatched v1 too and when I start atmosphere, I have this message

FATAL ERROR OCCURED WHEN RUNNING FUSEE.BIN UNABLE TO IDENTIFY PACKAGE​

You must update sd files first.

 

[detilmalala]

here the info of the nand, I clarify that without the chip it starts perfectly, with the chip only the hekate works, neither original mode nor atmosphere works

I also have unpatched v1 with picofly and it works perfect. Check your sd files.

the files on the sd are the same that work fine on the v2, lite and oled that i have made. Does v1 have something different?

the error i get when i start cfw

You really emmc nand chip work????
You have boo1 boo0 raw nand gpp???
Full nand backup??
Try boot hekate cfw Atmosphere from another sd card fat32 brother.
Your sd card must be not fake..orginal

Try to remake the hekate + atmosphere + fusee again.
If its still failed then your nand partition might be corrupted.
Thats what i think.

With the chip placed, the console does not start in original mode, if I remove it, it does start original, I already changed the micro sd card for another and the same result
