I am a little confused about the odex and deodex terminology. I am looking at various mods or hacks and I'm afraid I could mess something up because I don't know if I am deodexed or not.
I am on the stock ROM, I flashed chris41's stock kernel repacked with CWM and I rooted by installing zip of su and bb from the market. That is all I have done so far.
With that being said, am I deodexed or odexed?
Thanks in advance
P.S. I did search for the answer but did not find one.

Odexed - In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
DeOdexed - Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
In summary, Deodexed ROMs (or APKs) have all their application packages put back together in one place, allowing for easy modification such as theming. Since no pieces of code are coming from any external location, custom ROMs or APKs are always deodexed to ensure integrity."

I think most stock roms are odexed...
Thanks for the info, that helps me not make a big mistake installing the hotspot hack and AIO mod.
What exactly does that do? I don't wanna mess my phone up
Thanks

Seems like if you follow the instructions on odexing in the dev section and only try it on the roms they indicate you should be fine.
Here's an explanation of what odexing is:
"ROMs usually come in DeOdexed, and Odexed.
Odexed - In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space.

basically odex roms are smaller but no theming is allowed, but deodexed can be themed.

Zipalign
zipalign is an archive alignment tool introduced first time with 1.6 Android SDK (software development kit). It optimizes the way an Android application package (APK) is packaged. Doing so enables the Android operating system to interact with the application more efficiently, and hence has the potential to make the application and overall the whole system much faster. Execution time is minimized for zipaligned applications, resulting is lesser amount of RAM consumption when running the APK

Okay, here is why Stock Roms are not Deodexed.

Advanteges & Disadvantages
The advantage of deodexing is in modification possibilities. This is most widely used in custom ROMs and themes. A developer building a custom ROM would almost always choose to deodex the ROM package first, since that would not only allow him to modify various APKs, but also leave room for post-install theming.
On the other hand, since the .odex files were supposed to quickly build the dalvik cache, removing them would mean longer initial boot times. However, this is true only for the first ever boot after deodexing, since the cache would still get built over time as applications are used. Longer boot times may only be seen again if the dalvik cache is wiped for some reason.
Note:Themes for android come in APKs too, and if you want to modify any of those, you should always choose a dedoexed custom ROM.

This is deodexed system part of G900FXXU1BNL2 ROM.
It's for chiefs and devs only and cannot be flashed directly.
Because i don't have S5 device, i cannot test it by myself. So, i'm asking qualified devs with S5 to try to make ROM based on this package and make a report if it can boot or even work.
Some important notes:
1) Because almost all APKs were originally odexed, all of them were required deodexing and then signing. So, original signatures are lost. I've used standard android development test certificate. Usually it's ok for system APK which never update from Play Store (only through ROM updates).
Thus, probably some APKs won't work correctly. You can delete such APK and replace it with one from Google Play store. Btw, Play Store is also resigned and may be won't work with Google servers (need to check).
Also, all resigned APKs won't be able to update in Play Store - so you need to replace such APKs with those from Play Store as well.
2) Following APKs i wasn't able to deodex without errors and not include in package:
Maps.apk
Music2.apk
DocumentService.apk
3) In Android 5.0 APKs having library, they are placed in lib folder of APK sub-folder. While deodexing, i've put these libs inside APKs. Probably, you need to extract these libs and put them all into /system/lib (same as all pre-5.0 ROMs).
4) I've placed APKs similar to pre-5.0 way (not every apk in its own folder). I hope it will work this way. If device won't be able to boot, then place them as in original system structure.
Those, who can build the ROM, please test it and tell me about result.

Update 1:
- contains only modified parts of system, i.e.: only framework, app, priv-app dirs.
- app and priv-app dirs now have correct structure: each apk in its own dir and lib sub-dir.
- not re-signed, i.e. all apks contain original Samsung or Google certificate
- oops, i've forgot to delete Maps.apk, Music2.apk and DocumetService.apk - they were deodexed with errors and most likely won't work.

Nice build
Sadly im just a normal rom builder with knowledge on v4.4 and below, idunno on v5.0 have to learn it to make good roms out of it
Procedures with 5.0 should be the same. The only difference i've found is placing apks in separate subfolder. I think, it required only for pre-odexed ROMs. So, just need to make an usual ROM, same as 4.4 and then check if it work.

Very good than ill give it a try when home
But im not an advanced dev sadly dont expect much [emoji14]
I've tested it out, by putting all your deodexed apk's in their folders of my odexed XtreStoLite 2.0 TW Lollipop BETA ROM (and removed the 'arm' folders), also extracted out the lib files from your apk files, and put them in the 'lib' folder.
And replaced mine framework folder with your deodexed one...
But the phone doesn't boot up then.
So your deodexed files are probably not working.

logcat would be helpful.
Also you can try it step by step. At first, use odexed framework, and my deodexed APKs in subfolders (use my framework.apk and twframework.apk for certificate match).
Then try to put deodexed APKs into common folder (like 4.4 ROM).
If either of above will work, then try to replace the framework jar files.
It's not exactly because of wrong deodexing. May be you need to keep /arm/boot.* files in order to pass initial boot. And then may be OS will re-create new boot.
So, need to try different combination and look what you get in logcat. May be 5.0 requires some additional steps for deodexed ROMs.
Btw, after extracting libs, don't delete them from APKs.
Just checked CM12 ROM structure:
1) copy each APK in its separate folder (same as stock 5.0 ROM).
2) extract lib to separate lib folder (same as stock 5.0 ROM)
3) all arm folders should be deleted (including framework/arm)

can you provide logcat? FC may be related to incompatible certificate.

I don't see anything about SamsungCamera3 in logcat... If you get FC, then at least FC reason should be shown in logcat.
If it fc post the dumpstate_app_error.txt.gz from data/log rather than taking a log. Guaranteed to include all info

While deodexing i didn't touch neither resources nor manifest, only injected dex then signed and then aligned. Probably, because re-signed apk uses different certificate (obviously, i don't have Samsung's private key), OS denies some system level access.
Usually, when i create custom ROM i resign all APKs which use Samsung certificate - thus all system APKs share the same signature and everything works.
Why do you resign all samsung apks? System apps do not require signing unless manifest is changed. Is this something you have always done?
Disabling signature checking may fix this then I guess or not resigning in the first place

No problem, i will update pack with updated structure without resigning.
In my custom ROM i do many changes, sometimes including manifest change and adding additional system APKs imported from other devices or written by myself.

WHAT IS AN ODEX FILE?
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space.

THEN COMES DEODEX
Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
