[TWEAK][CM7]ODEX CyanogenMod 7.2 Flashable Zip

Flashable Zip to ODEX CyanogenMod 7.2​
I've heard that an ODEXed rom can be faster that a deODEXed rom, or at least the apps will load faster. This may or may not be true, but ODEX does provide one noticeable advantage that the system apps and frameworks no longer require storage space on /data in the dalvik-cache. It uses more space on /system, but there is plenty to spare there with CyanogenMod.
One of the main reasons roms are usually deodexed is to allow themers and the like to easily edit apks and frameworks. Since cyanogen has the Theme Chooser app that doesn't need to modify files, I decided to try odexing. This is loosely based off of a script by Decad3nce for the Hero.
So far I haven't noticed anything broken by this, and it seems a bit faster. I have no way to tell if its actually faster, but there's no harm in trying it for yourself.
Advantages:
More free space on /data
Possibly faster app loading time and phone bootup.
Disadvantages:
More space used on /system (so what?)
Moding system apk files and framework not easy. (ex. Theme flashable zips won't work, but CM has its own theme app that still works.)
Instructions:
NANDROID!!!
Flash zip (be patient, it takes a while)
Reboot
How to flash a new nightly: IMPORTANT!
Flash cm_epicmtd_full-##.zip
Flash gapps-gp-20110828-signed.zip
Flash auto-odex-cm7_2.zip
Notes on using custom kernels:
Custom frameworks: If the kernel (or anything else) flashes any .jar file in /system/framework/ you MUST flash it before odexing. If you want to flash after odexing, open the kernel zip on your computer and delete the jar file from /system/framework/.
Zipalign: Kernel's that zipalignshould be flashed after this. My odex script deletes the classes.dex file from every app/framework it odexes which modifys the zips. I haven't verified this, but I am assuming that negates the effects of the zipalign.
If the kernel both zipaligns and has custom frameworks, you must make a choice of which feature you find more useful. If you want zipalign more, delete the custom frameworks and flash after odexing. If you want the custom frameworks more, flash before odexing.
How to undo (deodex):
Do NOT just delete the .odex file from /system/app or /system/framework !!!!!
You have two options here:
Advanced restore nandroid of /system
--OR-- Reflash CyanogenMod and Google Apps.

auto-odex-cm7_2.zip - 948 KB
This has been tested to work on CyanogenMod 7.2 Nightly 12 and 13.
It should work on any other nightly or the RC0, but no guarantees...
How it works:
The flashable zip runs a script that runs a program called dexopt-wrapper on every framework file in BOOTCLASSPATH order, then every system apk included with CM and gapps. It then deletes the classes.dex file from all of those frameworks and apks. Last it clears the dalvik cache since much of it will now be unneeded.
The dexopt-wrapper binary doesn't do much other than properly run the system's dexopt binary with the right arguments.
Credits:
Inspired by a script by Decad3nce
zip binary: taken from metamorph app's googlecode site.
dexopt-wrapper binary: Not in CM, so taken from random mediafire link
Author unknown, but here's what could be the source code

Do you mean how to ODEX a previously DEODEX'd file? All the ODEX custom ROMs I've seen are flashable... unless you are discounting those done via ODIN... but that doesn't make up the bulk of ODEX ROMs.

Flashing this with Burrito Manager right now, I'll let you know how it goes =]

Just a thought but if you delivered deodexed files and then deleted the odex file associated with them when you installed and then ran this script on the files you added or modified after the install it would be like delivering odex or deodex to whoever wanted each version and it could key off some config file or just check for the presence of an odex file in the system directory to determine if to odex after installing or not.

He did say that the mod is already flashable. And he didn't specify whether it was previously deodexed because A.) it doesn't matter if the mod had once been odexed and subsequently deodexed, or was and always has been deodexed, and B.) why would he ask how to odex an odexed file? That's an easy one: "step 1.) Don't do anything. step 2.) there is no step 2... (no, don't profit - you haven't done anything)"

I think you misunderstood one of us. I did not suggest that anyone ODEXed something that was already ODEXed, nor did I suggest that anyone else what inquiring how to do that. Maybe you need to re-read it?

I don't believe it's possible to odex files outside of the phone. The odexing process makes use of the dexopt binary on the phone which is part of andriod. I think you pretty much have to do it manually on the phone, or write a script to do it from a flashable zip.
As for flashing new files then odexing them to a rom that has already been odexed, that must be done carefully. If you are just changing an app, then just delete the odex file, replace the app with your deodexed version, then odex it if you want (doesn't have to be odexed). If you want to change one of the framework jar file, you should probably revert the whole rom to deodexed first. The frameworks have to be odexed in BOOTCLASSPATH order, and before any apps are odexed. If one of them is replaced and reodexed later, things will break. Also, if the odexing of any of the framework is changed, it invalidates all the apps that were odexed.
It is possible to leave the framework deodexed and odex just the system apps, but that probably isn't even worth doing, since everything uses the framework, where only relatively a few of the apps are system apps (at least when you have 200+ apps). But this does allow the framework to be modified easier.
My reasoning behind odexing both the framework and the apps is that this is cyanogen. The framework files shouldn't really need modified for anything. Seems like it should be easier to make any changes in the cyanogen source.

Check your ODEX thread. Did you give a look at tanimn's odex tool? I posted it there.

Has anyone tested this, other than zmann of course? Just wondering if anyone has noticed any pros/cons. Also, would it matter which kernel one was using with this mod? The smooth scrolling mod in the newer samurai kernel modifies the framework.jar somewhat i believe.

This worked wonders nightlys 12-14. After flashing the latest samurai kernel with scrolling cache fix, I flashed this again. Did not work. Boot looped. That could be my fault though.

Samurai flashes one of the framework jars, so the one way for it to work is if you reflash nightly and gapps, then samurai, then this.
I've been running this for a couple days on 13 now and it seems so much faster. I don't seem to get the random slowdowns that always seemed to happen with just about every rom.
Edit: its had 40 downloads, so someone must be using it.

After every nightly, flash gapps, then this. If your flashing samurai, you should flash it before odexing since it modifys framework. If flashing my kernel, flash it after odexing since it zipaligns the system apks.

Ok, thank you. That clears things up alot. Was just getting ready to flash this using your kernel and was gonna flash it before, so you saved my a## there Thank you for this and a great alternative to the samurai kernel. I like them both, but yours is definatly great on battery savings and stability. Great job.

thanks for the info guys. im gonna go ahead and give it a shot. theres still a few things that are unclear to me. one, if i flash the kernel affecting the framework and then this, would the modifications to the framework in the odex zip nullify the modifications used in the smooth scrolling tweak? and two, if i use a morph to theme the lockscreen, will it work with this, and if so should i flash the morph before or after flashing the odex zip? thanks again for the help, i hit the thanks button for all three of you.

[Q] Question to devs

Hey just to fill my own curiosity (I am not a developer), when you guys deodex and zip allign a rom you create or are customizing...what effect does it have on the way the rom runs?
Or what are you doing?
thanks and I was just curious.

zipaligning is supposed to decrease ram use and increase performance.
deodexing removes the .odex files that go with system apps and puts the information into the apk. it basically makes the app ready to decompile and compile so that modifications can be made. it doesn't really have a positive performance advantage except that it might free some ram, if it make things quicker I'd imagine the factory wouldn't create odex files to begin with. also it often introduces bugs like broken apps or android system force closing on startup.

My understanding is that prior to de-odexing its actually faster and more stable, but when you de-odex it makes it so that you can make changes that you otherwise would not be able to, such as themes, ect.
X,
Using CK(simple).

Exactly right... actually an "odexed" rom runs a little smoother and faster and you can theme it, but once the theme is implemented that's it... you will have to flash only odexed themes, which requires theming of the apk and the odexed apk... its just a lot easier to mod and theme a deodexed rom...

[ROM][FC19][BML][MTD] Stock Odexed Prerooted

This is all Darkierawr's work putting this together. He asked me to release it if I have time as he does not. So I tested both files by Odining back to stock, rooted and flashed the BML then the MTD version from there. If you see Darkie around make sure to hit a thanks for him.
The MTD version will convert you from BML also and that is a big thanks to Toadlife for his conversion script.
So this is a flashable of the odexed full stock prerooted of the FC19 leak. Big thanks to Whosdaman for getting the tar for us.
The FC19 modem is here: http://d-h.st/eU1
For Odin installation of modem - Odin 1.85: http://d-h.st/i1Q
This was rooted with shadowkernel so thanks to Bbelos!
The FC19 leak had the Sprint Connections Optimizer conspicuously missing so was this a backup plan? Who knows. Check it out if you like.
BML version:

MTD version:

very nice
Finally a flashable as usual u guys rock!! any reason not deodexed??
Odin is still definetly the way to do it.. coming from fc09 all the apps came with but still have 4g randomly coming on plus random reboots and freezing up when scrolling through the market hopefully this fixes all that. would still love to have sound for boot animation and some kind of sutdown animation would rock... any chance??

Taking 2nd just to say "thanks" and hope you had fun at the birthday party! I'm way too happy on Rom Populei v2.1, but if I ever need it, I'm glad the genius of KG123 brought it!

Coming from Odin of FC09 on BML this has all stock boot ani and sound. The MTD kernel used has the flashing Android waiting for you to stick in bootani and sound of choice. As for deodexed...easily done with Xultimate or deodexed tool of choice. If there is a big demand for the stock deodexed FC19 leak I will do it for you guys. I think Sleeper also posted a deodexing and odexing tool.

A quick google will get you better answers but odexed means each apk in app folder and each jar file in framework folder is coupled with an odex file making it more difficult to theme or mod. Deodexed combines needed info into the apk files as well as in classes.dex. Then just the apk or jar file can be modded.

So any chance of getting a deodexed version?? appreciate all the help just dont want to screw it up trying to change to odexed version.. haven't tried that yet.

The only thing deodexed is used for is theming and modding.
If you're not going to be doing either of those flashing this should be fine.

How do we strip out the Sprint bloatware? Once it's rooted, can it just be uninstalled? Or will it come out with one of the uninstaller apps?
I think it's time to try something stock again- as much as I like ThunderHawk4, I'd really like my data to work correctly by itself all the time.
I have a personal [unproven] theory that different phones react differently to different ROM/kernel combinations. My first EPIC definitely played better with a greater variety than my current refurb. Maybe STOCK is easiest for some?

There's not much point to re-odexing a firmware. It saves a tiny bit of time on initial boot, but that's it. It has zero performance impact once the device has booted, and makes maintaining a firmware very difficult. (This is, for example, one of the reasons why Cyanogenmod doesn't odex builds.)

[DISCUSSION] Deodex vs Stock

From trying Alexis to Xtralite and Xtrestolite MM roms, what do you find overall better stock or deodex, in terms of battery, UI, bloatware, speed etc.
Post screenshots of SOT or whatever you feel necessary.

Some mods and tools don't work on Odex either. Which is why the majority of Ron's are deodex

[Complete Guide] What is Odex and Deodex ROM?
Advantages & 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.
