Hacking Hardware Picofly - a HWFLY switch modchip

[Freeman93]

How did you guys fit The picofly in the lite? I bent the metal shield a little so it barely fits on the right side of the CPU, but I'm worried the pressure might break off the resistors on the RP2040, is it safe or do I need to dremel a hole in the shield?

I put it on top of the emmc cover(remove the foam), and cut out the metal shield cover L shape leg to fit

That's a good idea, I'll try that tomorrow, thanks

on top of the eMMC

Sorry for the ignorance but how can I tell if the mosfet is broken or burned? I accidentally soldered with high temperature for a long time at the mosfet, I am afraid that turning on the switch with the broken mosfet may affect the switch

What is the resistance value of lite on the diagram? Can someone help me? My LITE vol+may not work due to this, it is missing.

I have done that, the pico light will return white-blue-cyan.
And the cyan means something wrong with the mosfet, line, etc.

It doesn't fit at the APU's right side? Near of ground's lite soldering point.

It was my intention, because I will start this night hopefully.

It's my understanding that the lite schematic is an older photo during early development.

It has generally been accepted that resistors in the 47-50 ohm range are acceptable, and people using 470 or 4700 + ohm resistors are corrupting their boot0 on the emmc.

With that in mind, I am attempting a switch lite install today, and was planning on using the usual suggested 47 ohm resistors.

EDIT: If you are asking for resistance values on the pads in the small orange square to the bottom right of the photo, then I am not sure of that at this moment. I haven't opened up my lite to see.

Thank you for your reply. The location is in the red box, not DAT0, CMD, CLK

That position will not work for lite, emmc side has more rom thanks to the speak next to it

I saw a guy in YT showing the led light trought the one of the speakers hole.

I don't know if he cuts off the metal back.

I still suggest to use this 3v3 point. much easier to solder.

Does this apply to Mariko v2? Or lite only?

It appears to only apply to lite, although there are alternate 3.3v points on Mariko and Erista as well.

Man....

we need someone(s) to make guides both with and without the flex cable so people stops asking the same questions over

I could attempt to write-up and gather photos into two separate posts, the question being do we pin them in this thread, or do I make yet another set of topics that will further split us between here, the AIO thread, and the guides?

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

Tried to flash 2.64 from 2.61 via update.bin from both the wiki and the post here, but either way I try, it remains at 2.61. Any ideas?
File is called update.bin and in the root of the sdcard. Toolbox says flash was successful.

Edit: Nevermind. After the 5th attempt or so, it took.
