The World's Ugliest Tutorial On How To Mod Beat Saber On Multiple Profiles Even Though You Really Probably Shouldn't Do This

• Use MBF to install mods on your normal profile before making a second profile (after is untested, and presumed to be problematic)
• Make your second profile on the Quest, and redo all of the steps required to enable developer mode on this second profile.
• If BeatSaber doesn't show up on the second profile:
• • Run adb shell pm list users to get your second profile's ID (the first number next to the name of it)
• • Runadb shell pm install-existing --user [user ID] com.beatgames.beatsaber

Now you should have BeatSaber on both profiles, "modded", but with no mods... If you had your ModData directory on this profile, it would be working as intended, so how do we get it there?

Well, unfortunately, no app can access the obb directory anymore to copy the directory that way. adb can only access files on the primary account, so we can't copy it that way either. You still have many options, but they are all fairly tedious. Some random ideas are using Dropbox or something, zipping up the directory and dropping it on a file uploader site, or even possibly what I did

This is an extremely ugly and messy way to do this, but I feel the need to document it regardless, in case this ends up being convenient for anybody else, or there are issues with other methods.

• Pull all of your mod data from your primary profile (mkdir ~/bs && cd ~/bs && adb pull /sdcard/ModData ./bs/)
• Delete all of your replays and songs out of your pulled mod data, for a much faster time copying
• Acquire Python with pyftpdlib somehow (for me, nix-shell -p 'python39.withPackages (ps: with ps; [pyftpdlib])')
• Temporarily open port 21 on your firewall somehow (for me, sudo nixos-firewall-tool open tcp 21)
• Run an FTP server hosting your mod data cd ~/bs && sudo python3 -m pyftpdlib -p 21 -u q -P q
• Install "Material Files" on the secondary profile of your Quest (I downloaded the apk from F-Droid, used adb install to install it, then ran adb shell pm install-existing --user 10 me.zhanghai.android.files to get it on the second profile)
• Open "Material Files" inside the headset
• Go to Add Storage -> FTP
• Enter your computer's IP, and set username and password both to q
• Copy the ModData directory, and paste it in the root of your Quest's storage

After all of these steps are completed, you should have fully modded Beat Saber on both profiles. The second profile will have all of your mod data, but do not be concerned, it is now entirely separate, and you can change any settings without it affecting your main profile.

Due to ADB not supporting multiple users, there is no way to add support for (the second part of) this to any PC modding tool. However, if nobody finds a universally easy way to copy the ModData directory, it would be possible to make a small online app to assist with it.
