Samsung Galaxy A22 4G

Your warranty is now voided. Same with the Knox Warranty Bit. I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in the GSI you want to flash before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

Steps to install TWRP

• Flash TWRP in AP slot and vbmeta in userdata slot in Odin3
• Boot into TWRP
• Wipe -> Format data >Type 'yes'
• Go to advanced -> terminal -> type multidisabler
• Reboot into TWRP
• Download Dynapatch.zip
• Flash Dynapatch.zip

Steps to install GSI

In TWRP

• Wipe -> format data -> type 'yes' then swipe.
• Wipe -> Advanced wipe -> select Dalvik, data, cache and swipe.
• Install -> select IMG file as 'System Image' and swipe. (Note: Extract your GSI.img.xz to .img using WinRAR or 7zip on PC)

And you're done!
