I am using S908N variant and want to use the Magisk module rom. But my firmware is not the same. Should I wait for the next one?

It seems odin even doesn't started flashing file
Likely connection issue
Reboot both pc and phone and try again
Also make sure, you are not using extention to connect device but connects pc and mobile with single cable
Also path shouldn't be too deep, keep files to flash on desktop in single folder

So will the T4 rom work on S908N or not? If so will it work on newer firmware?
I realize it can be a bit confusing (especially if you're relatively new to this). But if you search through here for the most recent changelog (Hint: https://forum.xda-developers.com/t/...-all-s22-i-dr-ketan-rom.4414933/post-88007497) and follow the download link(s) until you find your device and version of Android, you'll find what you need and a file with very simple instructions. Enjoy this beautiful ROM with a breakthrough installation process!

I flashed and it works great. All the modules work smoothly and installed the apps from the rom tool. I guess the firmware difference wasn't significant to fail installation. 👍

    No
    Essential fix requires only one time after flashing ROM.
    Edit :
    Applying long press home everytime is bug, probably Google change something recently. Will try to fix in next version

    Phonepe opens up fine when trying to send money it says, its rooted. BHIM after entering pin says its rooted
    I can confirm that a banking app called "mada" is detecting root on latest full rom.
    But I've updated from T04 to T05 using home csc to perserve data. Everything went smooth except for this app.
    Try this
    Enable secure folder and add root detecting apps to secure folder and use from there.

    Installation
    : State of the art Installation procedure.

    Detailed installation guide separately available in download area along with ROM files for Full ROM and for magisk module read changelog post.

    WARNING

    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!
