Samsung Galaxy Note20 and Note20 Ultra (Exynos) - phhusson/treble_experimentations GitHub Wiki
Device
Overall useable. This device is misreported as A-only in some utilities. Use the AB image for it, or it will bootloop.
Steps to install
- Step 1 - unlock your bootloader by enabling OEM unlocking in developer settings
- Step 2 - Reboot to DOWNLOAD mode. On the warning about flashing ROMs hold down the volume up button
- Step 3 - Downgrade to Android 11, OneUI 3.1
- Step 4 - IMPORTANT! Setup phone, connect to the internet and wait 15 minutes. If this is skipped you'll be in PRENORMAL state and you will not be able to flash TWRP.
- Step 5 - Flash the modified TWRP image, you'll find it on the internet. It'll have november in the file name.
- Step 6 - Download and extract the AB image. Flash using TWRP, do a standard wipe
- Step 7 - Boot! It may take a little longer than normal and it may appear as if it's stuck on the "Note20 Ultra" screen. Be patient!
