[Q] Downgraded?? topic

I was on Android 5.0 lollipop when something glitched and my phone wouldn't get out of bootloader mode, so i flash stock android. When it then finished and went back to 4.4.4 i tried flashed the factory images again to lock the bootloader, but it wouldn't let me because it kept saying "downgrading" or something along those lines. Now my phones sysetem version is 21.11.17.titan_retuaws.retuaws.en.Us which is the one of 5.0 when im clearly on 4.4.4. I am currently rooted with a custom recovery, any ideas on how i could possibly get back to android L?
