[Samsung Galaxy S22 Ultra] dr.ketan:
Here some common Q/A regarding Magisk ROM which new users want to have.

What is Magisk ROM?

Magisk ROM is small modified part of ROM which applies systemlessly. Though modification remains same as full ROM. Most of OneUI based full ROM have hardly 2-5% of modification systemwide but it integrates to system to make a full ROM. Magisk ROM also have same modification but it is systemless and use magisk overlay function. So, modification part remain same whether it is Magisk or Full ROM

Why Magisk ROM choosen over Full ROM?

Actually when S22 released, For long time there was no option to modify system because of new f2fs system ro partition type. So during this time I have choosen to make Magisk ROM so user at least have an option for all the modification which I commonly have in my all previous full ROMs. At presently We have system-rw capabilities but yet it requires Permissive kernel. This again make development dependent on samsung source release programme. Also now most of my ROM users adopted it and are much happy over full ROM

Magisk ROM doesn't have system-rw?

System-rw is complete different thing. You can have system-rw with TWRP and flashing small tool with it to make system-rw. You will have full choice to you system-rw or system-ro. Magisk ROM will work on both conditions.

Magisk ROM is made with different base from my variant

Samsung stock ROM almost have 90-98% files same in system with different variant. My Magisk ROM hardly uses any file that is different variant wise. So if you are using different base in theoretically only almost files you are using are same in all variant.

What is Debloting option?

As said earlier system-rw capabilities have nothing to do with Magisk ROM, If you wish you can make system-rw and debloat what you want. Indeed making full ROM with system-rw developer needs to struggle to remove bloatware. As system-rw needs more space compared to compressed system-ro. So making full ROM with all partition rw, you must have to remove good amount of bloatware while with Magisk ROM have complete user choice what to remove or keep.

It is difficult to update new firware compare to full ROM?

No, most of OneUI based full ROM still ask you to update to latest stock firmwre before using full ROM. Updating stock firmware also possible without even wiping data (Though must make backup for safety), Read post #4 for more details. Sort procedure is - Update firmware + keep root all in one go → Update ROM module - That's it.

Changelog have ROM installation guide. Also Magisk ROM module may work if your base is ner matching. You can find more info in changelog post.

Apart from ll these queries, as a devloper Here some reasons why I prefer magisk ROM

Very easy to updte ROM. I have updated ROM as ealy as just few hrs only.

Easier Installation.

Easier Uninstallation : Didn't like ROM? simply disable modules and you are back to stock.

Support most of variant in One ROM. Also since A13, I am planning to add support for S22 (non ultra) devices too.

No feature wise limitation with magisk ROM.

What is Best way to Install magisk ROM?

Nothing special. Simply Root your device. It doesn't matter If you are using root with stock recovery or TWRP, You are using encrypted or decrypted data, using system-ro or rw. You are free to choose one suites you best. As far as you have rooted device, you can use Magisk ROM.

I prefer full ROM : Currently we are supporting full ROM with System-RW only for S908B, S908E and S908N. For other variant only option available is Magisk Module ROM

I hope these will make clear many points new users may have with Magisk ROM Module.

Regards.
