Samsung Galaxy A50

What works with fixes:

VoLTE
Bluetooth calls
In some unlucky devices none of the cameras work. I haven't worked out a solution yet.

Go to settings and search for Build Number and repeatedly tap the Build Number until you see a message saying that you have unlocked the developer settings.
Next, go to the Developer settings and enable OEM unlock.
Power off the device and boot in download mode with vol up + vol down buttons and plug in the USB (make sure the USB cable is connected to the pc).
In download mode you see the long press vol up option for unlock bootloader.
Unlock the bootloader (that will wipe your device so be sure you made a backup of your data).
After bootloader unlock boot up the phone and make sure it's connected to the internet, or this will trigger an rmm pre normal error.
Set up the phone without google account etc.
Reboot into download mode and flash the TWRP recovery .tar file for your device with Odin in the AP field.
Next, Hold vol up + power button while Odin is flashing until you are in TWRP .
Format cache, data and system in TWRP .
Flash the MultiDisabler-Samsung zip in TWRP .
Flash the Quantum Kernel for GSI's zip in TWRP .
Flash your chosen GSI .img in TWRP as system.
Flash the latest available - PHH-Magisk in TWRP .
Flash the Overlay + Build.prop file in TWRP .
If needed, flash your chosen G-APPs file now.
Boot into the OS using reboot to recovery. (First Boot may take a while)
