Installing Custom Recoveries

A. Preparation.

1. Download firmware for your device

2. Extract ap file using Zarchiver and extract recovery.img from recovery.img.lz4 and compress it to recovery.tar

3. Patch the ap file with a magisk which will patch both boot.img and vbmeta.img (from magisk, choose install then select file to patch)

Exynos 850 Resources

t.me

Alternatively you can extract boot.img.lz4 and vbmeta.img.lz4 from the ap file and compress them into a new tar file and then patch that file.

note: if you don't want root then just extract the vbmeta.img and use zarchiver to add it to my twrp.tar file.

For Exynos 850 android 11 use a21s patched magisk.

For android 12 and most other devices use delta magisk

4. Unlock OEM in developer options
