Resolved compiling issues

Solved with a patch from another Samsung device.

Things needed to run this faster

Vendor kernel

Files for it are important but I can't understand which are for the vendor kernel and which are for the normal kernel.

How to enter Download mode

Press and hold Power+Volume Up+Volume Down while connecting a USB-A or Type C to Type C cable to a device capable of data transfer. When you see a warning screen, press Volume Up.

How to unlock the bootloader

Warning WARNING: Backup before unlocking! Data on the phone will be wiped if you do this.

Go to SettingsAbout PhoneSoftware Information, then tap the version number/build number 7 times until you see the "Developer options has been enabled" message. Go back to the settings page, tap on "Developer Options" then enable "OEM unlocking".


After this, turn off the phone, then press and hold Volume Up+Volume Down while connecting a USB-A or Type C to Type C cable to a device capable of data transfer. If the phone starts normally or enters recovery, shut down/reboot and try again. When you see a warning screen, press and hold Volume Up until you see a message regarding the bootloader being unlocked. Press Volume Up to unlock the bootloader.
