Atlast I suceeded to install Enegized Protection module on my phone and ads are completely blocked. Ainur Narsil didn't work; couldn't control volime level by volume button. So I go for viper4android fx and it works perfectly in compatibility mode. Thats the beauty of a rooted android phone. The most annoying things of this phone were lots of ads and lack of audio boost up, which are now solved. I use my own root file (as I'm not from India) and the idea is taken from you, so all credts to you. Thanks again. Take care.

Thanks a lot. It's working fine in one ui 3.0 . I rooted my m21 for adblocking mainly. Can you suggest some adblocking Magick module? Not apk.
You can adblock without rooting thanks to some using 3rd parties DSN service providing (DNS-over-TLS), I use adguard (russian based) by adding "dns.adguard.com" as a private DNS in "settings > connections > more connection settings > Private DNS". there are other services. NexdDNS is another service that I come accross.

This is noob question but when it comes to 2nd step . Should i get AP from here ? ( https://www.sammobile.com/samsung/galaxy-m21/firmware/#SM-M215F ) (i saw some other tutorials where people took AP file and patched it with magisk or something)
In short, yes.

AP contains most of the partitions of your device, the boot partition which is patched to root with magisk is also inside AP, so in those guides they're patching the boot file and then flashing it to the ap block.

While flashing stock you are flashing all the partitions that are in ap block and when you are rooting(using magisk) you are only flashing the boot image in the ap block.

In this case (for flashing stock rom) you need to flash the AP file along with BL, CP and CSC files you get after downloading the stock rom (from the link you mentioned above) in their respective place in odin.

    Working Saaar! :love: ( Galaxy M21 2021 Edition | SM-M215G/DS )

    UPDATE1:
    1> :cry: Bootloop happened
    2> Then Stock Recovery screen came up- Erase App Data!
    3> Then Reboot happened (Safe Mode) , asked to Factory Reset
    4> Factory Rest done.
    5> Now not booting (ONLY OFFICIAL RELEASED BINARIES ALLOWED TO BE FLASHED Message)
    I will try again.
    The solution is pretty easy. (I had the same problem while flashing twrp and Custom ROM on this particular device)

    Whenever this happens, OEM unlocking option in developer options is not visible.
    (even if you have unlocked the bootloader.)

    Solution:


    Enable WiFi, then going to settings changing the date and time by 10 days and finally go to check for updates and tap on update (it will say "error" or "failed to install" or something similar. Don't worry, this is expected.)
    Next go to developer option and you can see OEM unlocking is now visible.

    To test if its working, try flashing something.

    If its still not working then your Knox Security (e-fuse) has tripped. You can't do anything apart from going to a repair center or manufacturer.
