Hacking Hardware Picofly - a HWFLY switch modchip

I can edit the AIO thread. So please. You can PM them to me if you want.

Ok, I've decided I'm making a PDF for easier distribution.

Hm.. 2.64 shows an odd behavior on my patched Erista. When booting, after glitch succeeds (LED flashes green), the LCD screen turns grayish twice, sometimes thrice, before showing the switch logo. Doesn't show the atmosphere logo anymore either. Also, 2.61 glitches instantly (blue, green, within a second), while 2.64 keeps flashing blue/purple for at least 10 seconds before sometimes doing the gray screen thing and booting.

See .

Alright. I'm about to start on the motherboard. I added pics of what i'm working with for reference.
Few questions:

1) Are the mosfets in my image correct? They say "irh83422tnk". I ordered them because of the "irh8342". I am not familiar with mosfets.
2) If mosfets are correct, should I double them up and follow the "Mariko Dual Mosfet Install Diagram"?
3) My resistors should be good. 47 ohm.
4) Should I be soldering directly to the DAT0, CLK, RST, CMD points on the hac-emmc board OR the ones off the main board? ie: "V1 Patched/V2 Points" diagram

any help is appreciated. i have all the tools and can microsolder pretty well but I am new to the switch.

@rehius Unfortunately upgrading to 2.64 doesn’t fix the OFW issue for my v2. Still hangs, without any logo.

Any ideas as to how to debug this?

Hello, I created a 12 gb emmc partition on a 128 gb micro sd, and when I try to install some files on it, I get that sign, does anyone know what I should do?

1. yes
2. u can try with one if it doesnt work and u get blue then cyan use 2
3.yes
4. however u want i would get the pins on the board if u ever have to change the emmc

first its not english and this is english forum .
second what files u want to put where?

 

[rehius]

keeps flashing blue/purple for at least 10 seconds

that should not happen, really weird behaviour.
I have two v1, will check that later. it seems the best for you is to stay with v2.61

my pc is in Spanish, I want to put the atmosph, but I don't know if it can be mentioned here, the problem is that when I create emmc in the console, then when I connect my micro sd the emmc partition appears plus the other one that is in fat32 but windows says it needs to be formatted

 

[LexiconFumbler]

Is it an Oled?
If so check that CMD resistor with a meter. Should be 4.7 ohms. If it's off than it's likely damaged and needs replacing

It was a lite

if you still can load Stock using hekate, I would suggest to apply the official 16.0.1 system update over WiFi.
If you already have 16.0.1 on a SysNAND, you can downgrade it with daybreak before doing that (never tested, but will do that just to ensure)

well we cant help u in spanish maybe some can but this is a english forum so tell us what the issue says maybe we can help then

doesnt matter what what windows says u need fat 32 for switch
u made a partition base emmc i guess ?

u need to drop those files in the fat 32 partition where hekate is i would say

You keep mentioning "over wifi", is there an issue w\ wired updates?

 

[linuxares]

Why Windows ask you to format is most likely it say something is faulty on it. Just do a chkdsk so it gets happy.

I flashed back to 2.61 and it's immediately fine again, so yeah, seems to be specifically 2.64 causing it.

 

[Chonay]

Someone who would be so kind as to tell me what mosfet I need, Numbering or model to work the peak without processor cables, that is the only thing that is not clear to me since I already saw what the resistors are and the installation and connection points also already I have them, I only need the connection of the processor to the peak

PANIC OCCURRED WHILE RUNNING ATMOS... i am in 2.64, what does it means?

Make sure you use a update fusee.bin and all atmosphere files are copied over.

 

[Frullone]

Oook, I had everything tested but for some reason I decided to reflow everything and OF COURSE I bridges three small caps (those where you pick ground from).

But honestly, they just look like they're on the same trace and I would really love if I could avoid unbridging those little guys and leave everything as is.
Can anyone confirm me this and/or link some proper diagrams?

I'll attach pictures of my mobo and another one I found online with better resolution, for better trace checking
(They're both taken looking from the top of the Switch towards the bottom)

Based on the picture, I think your partition is too small. It says you need an additional 12.5 GB of free space.
