How to install/run ANY Switch firmware UNOFFICIALLY (WITHOUT burning any fuses)

Thanks for the immediate response!

EDIT: I just generated a new kip1 file and game card slot work again. Really apprecaite the help rajkosto.

Ok, the last step didn't work.
I can't mount the microSD via memloader.bin
Instead I got this:



What should I do?

 

idk what’s causing that but you could just pull out the SD card and connect it to your computer to set it up that way instead

 

Yeah that worked. But this is a very strange error. Everything was working fine with memloader before.

 

Did you use the memloader.bin file that has “usb” in the filename as that screen looks similar to one I got when I accidentally used the wrong memloader.bin file. Using the correct one fixed my issue

 

After upgrading from 4.1 to 5.1 I can't launch anything carts or downloaded titles from the eShop it all results in "The Software was closed". I tried it through CFW or OFW.

Edit: Ran bricmii and repaired the files, after that everything seems to work. Don't know why this step was mandatory as I thought it was just for using with SX OS?

Sounds like your SD card was missing ums_sd.ini in the root and/or possibly uboot/ums_sd.*




Following the guide, I'm able to boot to the new firmware using hekate but launching sx os gives me a black screen when choosing custom or orig firmware. Anyone know which step I may have messed up?

 

Check the red text at the top and also run briccmii and fix the files. That helped me with OFW and Hekate.

 

Thanks, after re-reading it again, I realize I hit (Vol -) instead. Good to go!

 

great tutorial

 

Nice work! Is there anywhere that explains what the patches are?

I assume nogc prevents the game cart slot update, but what do nocmac and nosigchk do?

 

Im stuck on a black screen at step 9 when I select lauch firmware and the FS_XXX option. any clue what is going on?

 

If anyone could assist I would greatly appreciate it.

I can't get past Step 7.

When I run the following command I get this:

c:\Users\Nick2\Desktop\SWITCH_Backup>ChoiDujour.exe --keyset=C:\Users\Nick2\desktop\switch_backup C:\Users\Nick2\Desktop\SWITCH_Backup\NintendoSDK Firmware for NX 5.1.0-3.0
Traceback (most recent call last):
File "ChoiDujour.py", line 101, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
[14112] Failed to execute script ChoiDujour

I assume I am not entering the correct command but not sure what is wrong.

I have the following keys in my keys.txt file which is in the same folder as choidujour and the firmware folder

HWI: XXXXXXXXXXXXXXXXXXXXX
SBK: XXXXXXXXXXXXXXXXXXXXX
TSEC KEY: XXXXXXXXXXXXXXXXXXXXX
DEVICE KEY: XXXXXXXXXXXXXXXXXXXXX
BIS KEY 0 (crypt): XXXXXXXXXXXXXXXXXXXXX

Thank you in advance.

 

I see 4 ncas as files, other as folders. mount via memloader/hactool. they have the archiving checked under advanced properties.

 

they have the 'a' attribute via total commander
