Exactly. Make habit to read any notice popup before applying any fix. S22 doesn't requires any fix normally. I have L1 and Netflix plying fine
I started all over again, I followed the PDF option 1 installation guide very carefully. I just read magisk update, reboot, applied the essential fix, reboot, just installed Updated Google store, reboot. The rom is original with nothing else. But already in google play netflix is not available? How did you manage to install netflix in HD L1 please? Thanks

Make sure safetynet passing
If needed clear data of play service and store and reboot
It may take few minutes to take play sore to have certified status. Once it is certified, Netflix should appear in play store

I just flashed again with the original rom S908B_EUX_S908BXXU2BVKB + unlock + install TWRP + install custom rom + last google play but nothing.
The problem must surely come from the root/TWRP? but I don't know much about it.
is it the safetynet-fix or the TRWP which should normally unlock the DRM?
Why do I have the safetynet pass ok but the DRM control which does not work?

Help me please 🙏

    Before you root your device you must be aware that

    • This will void warranty.
    • As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
    • There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but ROM is patched for all these mentioned features. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
    • There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
    • Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
    • Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
    • OTA won't work once you root device.
    • ROOT with caution.
    • You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.
    ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Regarding full ROM (for S908B/E)

    What I am planning is to make Odin flashable ROM from next version. Now a days on newer device you needs PC & Odin to flash bootloader so making ROM with TWRP flashable zip still you needs PC, Instead if I make Odin flashable ROM then it will be much easier. Even you no more needed to have same firmware installed.
    Installation will be swift like
    • Flash provided files with Odin with respective slot
    • Wipe/Format will be optional if you are already on my ROM. (must in case you are on stock/encrypted data)
    What you think?
    Proposed ROM development now onwards :

    Looking to poll results, it seems most users wants Full system-rw ROM including Mods. So finally found a way so users with any choices won't get disappointed.

    • To make a Full ROM + Mods (No Magisk module requires). This will only for S908B & S908E - This will be for users with choice 1
    • Above said ROM will have option in ROM Tool to remove customization, with this you can remove all customization and retain with pure stock experience. Before removing customization, still you can apply essential fix so it will keep all important systemless fix like SafetyNet/GPay etc. - This will be for users with choice 2
    • Magisk Model development will remain continue for all other variants including S908B/E

    I am Testing Full ROM including mods now on S908E, soon it will be public.
    Thank you for trust & support for ROM!

    PS : Full ROM is under testing now!
