Internal modchip - SAMD21 (Trinket M0, Gemma M0, ItsyBitsy M0 Express) Guide, Files & Support

Notice: I am not receiving notifications for this thread. I didn`t realise people were still posting in it.

Please please accept my apologies if I haven`t replied to tags etc... I have no idea what is happening. I`m subscribed to this thread but I am not receiving notifications. Please inbox me if possible. Or tag me in another thread.

Its amazing that people are still checking all of this out. I thank you for all of the help and support I have received in this thread over this year.

Cheers. Matty.


A video showing a modchip in action. Thank you once again to @metaljay for providing this. This is what you can achieve by fitting a chip!



Section 1. Gather your software.

Get your chip software from THIS THREAD.
Follow the flashing instructions there...




Section 2. Removing USB port and unneeded LEDs. (Adafruit chips only)
  • Next, we need to remove the USB port from the modchip. I recommend a heatgun or a rework station. Heat up until the USB port just lifts off the modchip.
  • Do the same for the LED just to the right of the USB port.
See picture:

You are now ready to fit your device. Proceed to Fitting section.





Section 3. Fitting modchip to your Switch.
New Universal Method. All SAMD-based internal chips. If your chip is not supported and you cannot work it out, PM me.

BUILD YOUR OWN FROM A QFP ATSAMD21E18. Trinket equivalent pins.
Flash Trinket bootloader using OpenOCD via serial pins SWDIO / SWDCLK. Fit a reset switch somewhere... Or going to power / wake (aka method 2). If building for external use, it is good practice to fit a third capacitor between 3V & GND. This is deliberately vague and ambigious, as this needs research and you need to know what you are doing.

Replacement Parts List

Ok... So you have damaged your switch soldering your chip in. Not to worry.

First things first, DO NOT BRIDGE THE CONTACTS HOPING TO REVIVE YOUR SWITCH. With resistors, you may possibly get away with this, but with the capacitors listed below, if you jump these points, you will make a nice short-circuit to the PMIC and / or the M92T36, killing them instantly. Don`t do it.

OK... I`ll list these parts with METHOD 2 & 3 TRINKET PIN NUMBERS and the values of the components they solder to.

TRINKET 3V (POWER SUPPLY) - 2.2uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 2 (POWER ON RESET - goes to pin 5 on M92T36)- 4.7uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 0 (VOL+) - 150R (150 ohms) 0201 Thick Film resistor. 50mW
TRINKET RESET (SWITCH POWER BUTTON) - 150R (150 ohms) 0201 Thick Film resistor. 50mW


I recommend RS components.

FAQ

Q - How do I boot the switch into APX (RCM) mode?

A - You need to short out pin 10 on the right joycon rail to GND with a jig or modded joycon or paperclip (not recommended... Buy a jig you cheap-ass gyppo). Once shorted out, hold down vol+ and power. The switch screen should be off... Plug into your PC and it should recognise a APX device. Well done. You are in RCM.

Q - What glue should I use?
A - Only glue if necessary! Ideally if your soldering is of sufficient quality and your wire is thin enough, you don`t need glue. I use a bit because I am OCD. Anyway, use Epoxy. It`s what I use. Gives you some working time, is solid. Superglue makes a mess DO NOT USE SUPERGLUE. The only thing super about it is how it melts things. Epoxy won`t stick to the shield long-term, so bear that in mind. Pure Acetone will remove epoxy. Acetone tends to remove / melt anything to be warned. CHECK YOUR GLUE WON`T GO CONDUCTIVE OVER TIME - LOOKING AT YOU SCAMSUNG! The combination of heat cycles and absorbing of moisture can turn adhesive into a high-impedance connection!

Q - What size wire should I use?
A - I use AWG40 magnet wire or AWG30 Kynar. AWG40 goes onto components easier... And if you snap it, chances are the wire will snap and not the trace / component.
A2 - You can also use AWG30. I recommend Kynar wrapping wire but any will do. Looks nice, good resistance to elements, tidy. Nothing thicker than AWG30. You are just causing yourself more headaches. Trust me.

Q - Is AWG40 thick enough?
A - Yes. AWG40 is good for around 90mA.

Q - which methods do you recommend?
A - Connect all the straps...

Q - how do you recommend to set it up?
A - Fusee Suite. Search for Fusee Suite or go to link at top of this OP.

Q - My switch is flat and won't turn on.
A - Have you got the charger connected? Disconnect it or your switch won't boot! Boot to a payload (SX loader/Hekate), reconnect charger and leave on the payload menu and charge. Leave for 15 minutes and switch will start normally. It will continue charging one booted.

Disclaimer:
You have only yourself to blame. This voids warranty. This may or may not get you banned from online services. If it does, you got yourself banned. I`m not responsible if you kill your switch / your first-born with any of this in this post. I`m not infalliable. I`m partly senile. Do your own research. Kids, get bill payers permission before you attempt even using a screwdriver.
NUTSHELL: Don`t come having a go at me because you fooked your £300 console up. I`ll do my best to help you though if you do, Just don`t blame me.

IF YOU REQUIRE SUPPORT, IF YOUR CONSOLE ISN`T WORKING CORRECTLY... PLEASE POST A HIGH RESOLUTION PICTURE OF YOUR INSTALL. You might think it isn`t your soldering, but in all cases with the new methods, it is bad soldering. So, please post a picture.


A BRIEF WARNING - PLEASE READ
THIS MOD IS NOT FOR THE FEINT OF HEART. WE ARE SOLDERING TO TRACES AND COMPONENTS ON THE FRONT SIDE OF THE BOARD TO SAVE HAVING TO REMOVE THE BOARD AND SOLDER TO TESTPOINTS. IF YOU ARE STRUGGLING, OR THINK YOU ARE GOING TO STRUGGLE, PLEASE PLEASE SOLDER TO THE TEST POINTS NOTED IN THIS AND OTHER THREADS (YOU WILL NEED TO REMOVE THE MOTHERBOARD). DOUBLE - TRIPLE CHECK EVERYTHING. YOU HAVE BEEN WARNED!!!
Good soldering skills are needed!
A magnifying glass is needed!
Good soldering iron needed - ideally with a 0.3 conical tip. No more than 30w!
SECURE YOUR WIRES PRIOR TO SOLDERING. Stick them down with double-sided tape.
Only use glue if you need to and glue wires after soldering. Don`t glue the solder to the component!
Put the tiniest amount of glue on the PCB mask only. Never on components. Use a cocktail stick for more glue control!!!
Take a look at alternative solder points to get you out of the sh*t if you do rip something off the board
If you aren`t the best at soldering, then think very carefully about connecting to pin 6 capacitor (the one in these new methods). If you rip this pad, you WILL NEED TO REMOVE YOUR BOARD and run from a testpoint.

hello my switch has all the straps connected, and it starts well without the charger, it injects the payload, but when it has the charger it starts the ofw, the chip is an m0 trinket with the Part_1_TRINKET_PERMA_CFW_Latest installed, it should not remain in rcm and start only when disconnected the charger to not burn efuse

Still not getting notifications!

Yep can fit a chip @pmc inbox me.

@edwardsalazar97 you are correct. You have a loose strap or an incorrect connection somewhere sir.
I already checked 10 times and as I say without the connected charger starts the cfw, but with the charger directly starts the ofw @mattytrog

--------------------- MERGED ---------------------------

I have the connected USB strap, the joycon, and the volume @mattytrog

And you are using perma part1 file?

Strange.

Try dropping the part 2 UF2 on there again but keep USB connected for 5 seconds after dropping it on there.

if I use Part_1_TRINKET_PERMA_CFW_Latest, I have already done it several times and the straps seem to work whenever I do not have the charger connected, when I have the charger connected it starts directly cfw, I understand that it should remain in rcm, until I disconnect it and so if it would start, right ? @mattytrog

Oh god, have I lost the resistance? or the component that goes with the volume + strap, now the volume does not rise, I managed to put a similar component that I found on an old plate, functional the volume for a while after it goes up only forever @mattytrog

Thanks @mattytrog
I had a look I actually do have some wick but I cant get it to take. I've moved the capacitor and i'm worried that i'll lift a pad.
If you can inbox me as I cant inbox you and if there's a way I can get this device to you i'd greatly appreciate it.
From you're responses you'll not want to accept but expect some donations heading your way for work done.


Many thanks.

@edwardsalazar97 no need to replace the cap.

i completely removed mine and bridged the contacts. i wasn't able to solder at this point. I made 20-30 attempts, with Fluxer, without, with leaded solder and without. No success.
If this SMD component is missing, there are no disadvantages (as long as the contacts are connected). It is also mentioned here in the thread over and over again.

if the problem is that I joined them but the volume button is always stuck @salitoshater

I have already solved it, volume + and - buttons working perfectly with 100 ohms resistors, the power button strangely did not work with any resistance of 100 or 150, it started working normal with 50 ohms quite strange but it already works

i think i ripped 1 of the 2 pins of the joycon mod, when trying to remove the solder, now my switch wont detect my right joycon, only bluetooth, what can i do?

that means no rcm mode also :/

@ShadyGame change the tape for a new one, and for rcm you can do it with a jig or a clip

--------------------- MERGED ---------------------------

@recgame77 I advise you to check the images well, if you do not understand it, it is best that you do not damage the console

it doesnt detect the joycon so it doesnt detect the jig either

im talking about this, the right pin, it came out along with the solder i guess

ok, I thought the damage was in the joycon not in the switch strap, when mentioning mod joycon I assumed that was

--------------------- MERGED ---------------------------

if you did not tear all the way or the track you can with a cutter remove some of the coating so that the copper is seen and join the two tracks
