He sent you his moveable.sed, which is completely useless to you. You will need to obtain your moveable.sed using Seedminer, and the first step is for him to run seedstarter.3dsx. Instructions are available at https://github.com/narukaioh/pkm , though you'll want to use the main fork of Seedminer available at https://github.com/zoogie/seedminer/releases .I do have my old Friend's code on my friend's 3DS.
My friend sent me the movable.sed. Is there anything specific I have to do or my friend have to do?
His system isn't homebrewed at all and he followed the steps to the guide and was able to get the movable.sed.
Okay, he doesn't need the Mii QR code at all?He sent you his moveable.sed, which is completely useless to you.

You will need a PC with powerful GPU hardware in order to run Seedminer. My hardware probably can't do it. If your PC hardware is inadequate, you can try the Nintendo Homebrew Discord, or there might be someone here who can help you.
Okay but, my friend doesn't have homebrew 3DS. That is why I asked.Read the instructions! (Specifically the "[B - No homebrew but friend with homebrew]" section.)
ETA: You can use a backup of your SD card; you don't need to use your actual SD card, in case that's not completely clear.
Yeah, he does have a New 3DS XL and he install luma on his 3ds. He has the movable.sed and he tried to decrypt it using ninfs and threeSD but neither seems to work, idk if he just doing it wrong but I'm out of ideas.Oh, when you said "he followed the steps to the guide and was able to get the movable.sed" I assume you meant he followed the steps to install b9s+Luma.
Does he have a "New" 3DS? Because if he doesn't want to install b9s+Luma (which is understandable), then he can use super-skaterhax to run seedstarter.3dsx, similar to the earlier instructions for running JKSM.
