Installation Instructions for Omega v21.1:
Android 4.4.2 Kit Kat firmware needs the new bootloader to work.
This mean the knox will be triggered and your warranty will be void, read more here.
If you are ok with this then continue, else get Omega v19 with android 4.3
1. Backup your device (nadroid backup, titanium backup, efs backup … etc) and save the backup to a safe place.
2. Flash the new bootloder and modems with odin
Bootloader -> BL_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_C ERT.tar.md5
Modems -> CP_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_C ERT.tar.md5
Power off device completely, then boot to download mode and flash bootloader and modems with odin like this:
Then boot to android and check if the new modem XXUFNA5 flashed ok (if wifi is not working is normal)
(If you already have the correct XXUFNA5 bootloader & modems, ignore this step)
3. Boot to Recovery –recommended TWRP, get the latest version from here -> and flash Omega v21.1 and then boot to android.
You can flash without full wipe if you are coming from Omega v20 or v20.1 or v21, if not then flash with full wipe

You can download Omega v21.1 from Omega’s Download Center
and from your device with Omega Files Pro app.
Omega Files Pro offers two fast Direct Links with pause and resume option.

    Facing the same problem as evenstar, stuck at the omega boot animation. I haven’t used the latest TWRP, could this cause the problem?

  • fifi


    as mentioned above, Android 4.4.2 requires the newest bootloader to work.
    As for now, I am on 4.2.2 MGA stock and I have no KNOX at all. Will Omega 21.1 install this KNOX thing on my device?

    Best wishes,
