Phone Need some help regarding Odex Files and corresponding apks

Hi guys, I got this problem in my odexed stock rom, I have this problem in sysui, gallery and calculator.
I downloaded 4.2.2 style sysUI, pushed it in the respective folder by replacing with its stock sysUI.
I rebooted my core, the statusbar was gone, so I deleted 'SystemUI.odex" file, then rebooted it worked!
In the same way, I replaced stock gallery with note3 gallery, and stock SecCalculator2
Luckily note3 gallery worked, but it doesn't support Sim2 so I can't change Sim2's wallpaper or make it same as Sim1's.
In the statusbar, I can't see most notification cuz its completely transparent, and also its a bit laggy.
Calculator never worked
So I wanted to replace these with stock, when I pushed it in system>apps> I noticed that there were no .odex files for .apks
I replaced them with their stock odex files, none of 'em worked, I guess cuz of the odex thing, so I again deleted odex files and rebooted, nothing worked..
Now, I need some developer's advice, plz don't tell me to "Flash Stock Rom via Odin" I can't do it...
Is there any other left way to make them work plz I need help..
