Tutorial  Updated

A definitive way to test if your Switch is patched or not (purchases after 07-2018)

This tutorial uses TegraRCM command line to send payloads to RCM enabled Switch.
Command line is used since it offers a more detailed explanation on what is going on.
So it is a definitive way to confirm if your Switch is patched or not without further questions.
This tutorial does not make any modification to your Switch console.

Requirement:

No Micro SD Card is required.
1. Any way of entering Recovery Mode. Please read here, https://gbatemp.net/threads/the-ultimate-list-of-mods-to-enter-rcm.502145/
2. biskeydump.bin payload(please get the latest version, as of 30th July 2019, the latest version is V9), can be downloaded from https://switchtools.sshnuke.net/
3. TegraRcm GUI, can be downloaded from https://github.com/eliboa/TegraRcmGUI/releases
4. USB C to USB A cable
5. A PC with USB port (Sorry I don't have Mac so I could not cover this area)

Step-by-Step (in total 7 steps):
1. put in your RCM Jig on the right joy con rail. Press and hold Vol+ then press the power button.
You should see a black/blank screen after you press the power button.
If you see a Nintendo logo, you can power off your console and try to adjust your RCM Jig position.

2. To install APX driver
2.1 Launch TegraRcm GUI, go to Settings tab, click on "Install Driver" button.

Confirm the driver installation.

2.2 For those having problems installing APX driver :
Install and launch Zadig. Plug your Switch in RCM mode, then select Options > List All Devices.
Select the APX device and check which driver is installed for this specific device. If libusbK is not the current driver, install it.

3. Plug in USB cable from your PC to Switch(in RCM).
Open TegraRcm GUI and you should see this window with "RCM OK".

Alternatively, you can use Device Manager to confirm if the APX device is recognized.

Now you can close the TegraRcm GUI application.

4. Copy biskeydump.bin to the TegraRcm GUI folder.

5. Open a command line and go to the TegraRcm GUI folder.

6. Run this on the command line
Code:
TegraRcmSmash.exe -w biskeydump.bin BOOT:0x0

7. Check the result
7.1 Switch accepts and executes payload, which mean your Switch is not patched.
Please refer to 0X7000

You will also see QR code on your Switch screen.

7.2 Switch accepts but does not executes payload, which means your Switch is patched.
Please refer to 0X0000

Hi, so I tried this method and I got 0X7000, I ran it twice just to make sure. however I want to make completely sure. My switch is on the the red patch list but orange on the Ismyswitchpatched. It is XAW4001540 and running v9. So is it patched or not. If its not which CFW can i try to run with less risk. Thanks.

Well when you did the test, did anything appear on the Switch screen? I would assume so if you got a byte smash of 0x7000

That pretty much confirms your console is not patched despite what your serial number is. Remember that the serial number is only a rough estimate and while it may be accurate some of the time, the real test is pushing a payload.
I see, I just tried again and its still the same. Lines of code, orange emoji and a barcode appear on the switch. where would you recommend to start first now that the switch is not patched ?

Since your console is already on firmware 9.0, you will need a CFW that supports firmware 9.0. I personally recommend Atmosphere and here is a guide that can set you up.

Hi.. didn't see this asked in the nine pages of very helpful information

Have a new used switch that says patched according to the websites

Still I understand this method is the way to know for sure

If I run the test and am able to inject and run the .bin can i still do a full NaNd backup. I plan on possible running cfw but going back to stock possibly one day to play online, etc in the Nintendo world online (i.e. restore if I don't accidentally get myself banned)

Also should i test to see if banned before testing it for patched/unlatched
Thanks in advance

I will return if patched and want to be fair to seller and not screw anything up

P.s.i have rcm loader if that makes testing easier..

Sending a payload doesn't taint the NAND. Only CFW & homebrew do. Also it is up to you if you want to test if it is banned or not.

Thanks a lot!! So I can see if it's unlatched. If it isn't then test to see if not banned. Then factory reset, backup nand and have fun with cfw.. when im ready to go back to stock restore nand. Sound right?

Is there an easy way to test if banned?

And hekate is what I need to backup nand?

Also, is it possible to accidentally patch or 'burn a fuse' on an unpatched unit?

Sorry for all questions just want to be thorough.

What site is best to read up?

Thanks again!!

The easiest way to check if your banned is by trying to use the eShop.

Yes, you use Hekate to dump the NAND.

And yes, it is also possible to accidentally burn fuses on an unpatched unit.

While not a site, you can read through this thread to catch up on Switch hacking in general.

Hi guys. I tried to mod my cousin's switch and it ran hekate, then tried to run atmosphere but after showing the logo it went black screened. If I got that far, does it mean the Switch is not patched and I'm doing sth wrong or is the switch patched?
