I am writing this on Firmware 5.1.0 Any Firmware below can be backed up, I will update this as System Updates come DO NOT BOOT CFW OR AUTO RCM UNTIL YOU HAVE A CLEAN NAND BACKUP!Tools Required Nintendo Switch USB 3.0 to USB A-Male Cable SD card formatted to exFAT (64GB is the Best option for NAND Dumping but I had to use a 8GB for this tutorial) Jig( A device to short pin 9 and 10 on the RIGHT Joy-con Controller) TegraRCM Loader(PC), Hekate 2.3 payloader, File Joiner To start off with into the World of a unlocked Nintendo Switch it is very important to get a NAND backup in case you were to accidentally brick your Device. The chances of a Brick are Low but the you Need this if you want to keep your Switch a little bit safer when diving into unlocking a Device! Hold Down the Power button on the Switch till you get the Power Menu screen and select power options then TURN OFF DEVICE. We must make sure during this entire process our device is turned off as even turning on the Switch during a partial NAND dump can make it corrupt. Insert your Jig into the Switch, It can touch pins 1 +10, 9+10, do not short out pin 7, it can render your device useless! Optionally you can go to Ebay or search on google for a Nintendo Switch Jig. Insert your SD CARD that has been formatted already. After that Plug in your USB C cable to the bottom of your Switch. Press and Hold Volume UP+ then at the same time hold the power button for 2 seconds then release both buttons. If done correctly your Switch should be on a black screen. If you see the Nintendo Logo try again or make sure your jig is shorting the proper pins. Plug the USB C cable into your PC, it should show up as APX and install, however it is not installed properly. Open the .rar file Proved in this thread and extract the folder to your desktop. Inside the folder is a application titled,"TegraRcmGUI_version2.0_Installer.msi" run this application and install. Once installed run the application and it will detect your Switch but say the driver are missing. select yes and follow the process to install the drivers. Once installed inside the TegraRcm Program the Red box on the bottom will turn Green, Indicating your Switch is properly in RCM Mode. It will ask to install Drivers for the Switch, select yes! Select the folder icon and go to the folder you extracted to your desktop and select the,"hekate_ctcaer2.3.bin" then select the Inject Payload Option. You Will now notice on your Switch the Hekate Menu Congrats!! But we are just getting started! To use this menu Volume up = UP Volume down = DOWN Power Button = SELECT Go down to "Tools" and press the power button. You will see a few different options. The option you want to choose is under the full section, choose "Dump RAW eMMC". **IF YOU ARE USING A SD CARD WITH UNDER 32GB OF FREE SPACE IT WILL DO A PARTIAL DUMP, NAND DUMPING CAN TAKE A FEW HOURS, BE PATIENT** If you have more then 32GB of Free space it do dump all of your NAND in one go. after it is complete press the power button, then select eMMC BOOT, this is part of your NAND and is a seperate file so keep it with the other file! once it is done press the power button, from here you can choose to install install AUTO RCM(so you do not need to use the jig everytime you reboot), go back to the main menu and power off, remove the SD card from your Switch and insert into your PC, and copy over the files into a safe place. Congrats if you DID NOT use a smaller SD you can Leave a like and Exit this TUT! If you are like me and used a smaller SD card it will do a partial dump, this means it will only dump enough of your data to fill the sd card and make a special file called, "partial.idx" KEEP THIS FILE ON YOUR SD CARD AT ALL TIMES! Keep an eye on your device, you will get a message saying the PARTIAL NAND DUMP is complete, press back, then LEAVE YOUR SWITCH ON and take out the SD card, insert inside your PC and put all the files EXCEPT the partial.idx file into a folder on your PC. Re-insert your SD to the Switch, then go back to the main menu, select the option," REBOOT RCM" this will reset the SD card.*You will then have you replug into your PC, use TegraRcmGUI and send the Hekate Payload to the Switch again* It will take 3-5 times before you get an entire NAND Dump. Once it is done select," DUMP eMMC BOOT" it is a small file. and then you will have to plug back into your PC and use TegraRcmGUI and send the Payload back to your switch to get the Hekate menu again. AGAIN. Go to Tool and Select the Dump RAW eMMC again. Inside the Folder you moved the files over too you should have 1 of the 2. 15 part files at 2GBS 30 part files at 1GBS Open the Joiner Scripts rar file provided and select the one that is correct to your file size (1GB or 2GB) and put the .bat file inside the folder with your nand files and run it.. it can take some time to put all the files together. once that is done congrats! You have a complete NAND Dump, keep this in a very safe place! **If your Joiner does not work , it means your nand dump FAILED! It happens some times, in this case unfortunatly you will have to delect all of your NAND backup and re-try! The file size should be 32GBS when Complete!
