    It all works fine. That's not my problem you see. Just that I have problems trying to use software like nxmtp or to usb install stuff on the switch. I was wondering whther other people had the same problem or it's something with Windows maybe

    I think you have your data pins backwards. I'd double-check all the connections to make sure.

    Hi,
    Very late to the part on the Trinket front so please excuse me. The install will be fine, I have total confidence in the wiring.
    I have read the first 20 or so pages and the last 40 or so but as there have been so many developments I'm finding it hard to grasp which where a couple of wires go and what a couple of functions are.
    Power, Ground and the USB pins are a given.
    The Diagram for Trinket suggests that pins 1,2 and 4 can all be ground, but also suggests Pin 2 on the Trinket can be used for USB Strap to prevent accidents. Is pin 2 a dual purpose pin? and am I better off using it for USB strap purposes?

    So, just to clarify I'm currently booting TX boot.dat and I'm running Emunand (9.0.1) with my 5.1 Firmware being completely untouched and truth be told never used.
    I guess more wires to increase Dual boot options can also be extended to include an option to boot emunand???(pure guesswork), but I already have that selected in the TX settings and don't really require stock (5.1) to boot with a TX payload... are there any other advantages? Pic says see thread for details but after many, many pages I haven't stumbled across the explanation for the "Pink Arrows".

    If indeed the pink pins are all going to ground they are the easiest pins to solder hands down so doing them is a no brainer... any disadvantages/risks to doing them?

    Thank you in advance if anyone can see themselves clear to advise without the obligatory annoyance or sarcasm :-)

    Forget the pink arrows.
    Wire the Trinket as in OP.
    Then you can use the Switchboot project to control the chip.

    There may be other UF2s out there but the wiring may be different?

    Pin 2 is configured on my diagrams to be the optional USB strap. However, on earlier installs, it was the wakeup pin. Even earlier installs, pin 4 was a wakeup pin.

    The wakeup pin in now obsolete.

    pin 3 = joycon
    0 = vol+
    USB signal lines = outer- outer, inner - inner
    GND - use pad next to battery connector (the groundplane loses too much heat, leading to dry joints.)
    PWR - choose a location. I prefer the nearest one (the M92t36 V+ filter cap)

    If you have a botched install with missing pins, it’s probably best to have a professional fix it before it gets worse...

    I’m sure if you ask in the thread for a fix, somebody will offer some help. I would show pictures of the botched install, and if it is actually fixable, someone close to where you are located will more than likely try help you out....

    Any chance you'd be willing to do an internal install for me? I haven't touched my console, but would like to get it going...

    Hola!

    I'll reply in English.

    21620002 is essentially unknown, at least to me. Make sure archive bit is active on SD card and you have any exfat updates.. also make sure your sept version is up to date.

    I'm releasing an update for all samd21 chips this evening. I'm just testing it now.

    oh wow, sure :O it would be my first time doing a mod as a service, but I'm very familiar with paypal invoicing and shipping, as I make and sell LEDs for the rhythm game community. if you want, you can send me a PM and we can figure out the details :)
