How much does odex-ing a rom actually help? - Vibrant Q&A, Help & Troubleshooting

I have this weird thought in the back of my head that this lag I experience comes from these ROMs being deodexed.
I remember when JK6 first came out, I tried an odex-ed ROM and I was flying. I can honestly say that was the first time I enjoyed Froyo on my phone. It just seemed to work like everyone says it should.
Now I've tried almost every other ROM out there (including stock JK6 deodexed, just flashed it) and it doesn't feel like it did before.
So does odexing actually help? Or was I experiencing some placebo effects there?

I am no dev, but as I understand things...
With odexed roms, certain apps are broken up into individual pieces apk, odex file, etc. Not everything gets loaded into memory at once. File I/O on the now smaller files (pieces) and the smaller memory footprint CAN (not always) contribute to a faster experience.
When de-odexed, these pieces are combined / all together in a single package and can only be installed on likewise de-odexed rom. Distribution. installation, modding, etc becomes much more convenient. With a proper lag free I/O system, whether a rom is odexed or deodexed should make little difference which makes de-odexing of roms the preferred method.

[Q] Performance - Stock vs Cooked

Hi, I cooked my own ROM using "osKitchen v1.25". I started initially by removing extraneous files such as the sample media and photos as well as some wallpaper etc. The final cooked ROM worked perfectly however, I noticed that my cooked ROM seems less fast and less responsive than the stock ROM even though is entirely based on it.
I experimented to make sure that I wasn't being paranoid so I flashed back T-Mobile's stock ROM and confirmed this. I did not, however, use any kind of benchmarking tools so it is not strictly scientific but I am confident that it is slower.
Since experimenting with minor modifications like removing extraneous files, I have made a lot of modifications to my ROM that I cannot go back to T-Mobile's ROM but I was wondering if there is something in the kitchens or some missing optimization that is only available in stock ROMs. I am curious if anyone else has experienced this as well.
Many thanks in advance,

Stock KE7 Deodexed Rom?

I found that SGS2 is really unlike SGS1 where you really need a custom rom to bring it up to speed.
As you can guess, I am rather happy with the stock rom. However because it is not deodexed, I am missing out a lot on the theming side.
So the question is, is there any deodexed stock KE7 or is someone working on it? In the old sgs1 day, Doc Rambone had a Roms kitchen brewing, I am missing that a lot

I've got KE7 deodexed somewhere, but tbh it's not worth the upload - VR1.1 is essentailly stock with a couple of tweaks and fixe, and isn't that different from stock as of yet. Dunno if that helps, but it might be an alright base, as it's deodexed and working etc...
Or you could deodex it yourself if you fancy a play around
Thanks pulser. I did consider vr but because it needed a wipe I am not willing to go thru the whole process of setting up my phone again seeing that 2.3.4 could be just around the corner.
As for deodexing for myself, I did search xda but strangely despite quite a bit of interest, no one has written a simple to understand guide. Well if you are up to it, maybe you could give us a guide, am quite sure it will be well received

[Q] ROM Recommendations and Advice

So, I've had my SGS2 for a few weeks now and have decided that I would like to flash a different ROM.
I have nothing against the Samsung stock ROM, but I am looking for something that removes all the 'samsung-ness' from the phone, i.e bloatware etc., plus my carrier (O2), amongst other things, has decided to include a bootscreen & sound that annoys me profusely! In the first few hours of owning the phone, I already installed Go Launcher Ex, as I wasn't a massive fan of the iPhone look to some parts of TouchWiz.
After doing quite a bit of reading around, I set sight on installing CM7. However, further research seems to suggest that features such as the camera and FM radio aren't quite fully developed, so I've been slightly put off.
So, in a nutshell, I'm looking for the following:
- Remove Samsung branding and bloatware
- A more android look and feel
- More tweakable
- Main features of the phone still function
- Fast and stable
- Receives plenty of development
Based on the above, could someone suggest a ROM that would be good for me? Villain maybe?
Thanks in advance
checkrom revolution
Theres are several Samsung based roms, that come with the Samsung apps removed. There are also Rom kitchens, where you can easily build your own rom.
For a minimal Sam based rom with an AOSP look you can try Gingermod. Or minimal TW roms like Exynos or Wanam lite.
If you want AOSP based, keep an eye on CM and Oxygen Rom (not posted on xda).

Dude,
From my experience, I can give you this advice :
Try CheckROM RevolutionHD V1.0 + Latest SpeedMod kernel = best ROM ever, Best freedom ever, best battery and No issues !
Really amazing combo
Brilliant, thanks for the replies. Regarding kernels, is there a particular ROM+Kernel combination I should use when I select a ROM, or does it not really matter?

CM7 ticks all your boxes, camera app works, I don't use radio so not sure on that. Camera may be slightly lower quality than stock if you don't mind that, for me not that much of a biggie as most my shots are done on a normal camera anyway.
If you want to stick with a TW rom than check out gingermod, best of AOSP mixed with Samsungs TouchWiz interface so you don't lose any of the stock functions like camera and such.

In Need Of Advice For Starting Over

First, an explanation of my situation:
I bought a Galaxy Note at the beginning of the summer. All-in-all, I was pretty happy with it. It was a much improved experience over my Atrix, which was in poor condition by the time I switched over.
I wasn't able to root at first as I only had access to a Mac, and there were innumerable issues in doing so - Odin was PC only, WINE ports of it failed to recognize the phone, the Mac equivalent of Odin (I am spacing on its name right now) didn't work with the Note, etc.
When ICS was officially released, I tried to update to it via Kies. Kies on Mac is a ****storm. It's incredibly buggy, toolbars and menus don't display correctly, it has trouble recognizing the device, etc. I was unable to get it to make a backup, but I eventually managed to load the ROM onto it...
... and that's when the real problems started.
My battery life has turned to crap. Everything runs incredibly slow. Everything's super buggy. Apps force-close all the time. My MicroSD card ended up getting corrupted - half of my music disappeared, of what was left only 1/3rd actually worked. I just reformatted my MicroSD, backing everything important up, etc.
I've been dealing with this for around a month now, as whenever I come to the forum I have no idea where to even start to fix this. I'm up for wiping everything and starting over, and I do have access to a Windows XP machine now so that may be easier... but I don't even know where to go from there.
---------------------------------------------------​
That's why I'm here - I need advice. I need advice as to how to clean up the current mess my phone has turned into and start over. I need advice as to what ROM to try and how to go about loading it. I need advice as to whether to root and how to do so. I need advice as to whether to install a CWM, which one to use and how to go about doing so.
Here is what I am looking for, ordered from most important to least:
Battery life is important to me. I loved how long the battery lasted before my attempted upgrade to ICS... now it lasts maybe 1/3 of the time.
I want something that will work - I want stability. No more constant force-quits of every freaking app.
A smooth, fast UI would be preferable.
Feature packed. I like the thought of cutting edge features of newer (or custom) versions of Android being incorporated - but this is far less important to me than battery life and stability.
My preferred method of installation would be using my Mac - but as I said, Windows XP is a very easy option for me as well. I could also install a newer version of Windows if need be, but would prefer not to go through that...
Thanks in advance for any help, advice and recommendations! ^_^
Get Odin and root your phone...
Download and flash TWRP... http://teamw.in/project/twrp
download a ROM of your choice
boot into the recovery ..wipe--->>cache/dalvik cache/ wipe ROM/factory reset..>then go to the install and flash your ROM...
These are very rudimentary instructions I hope they helped a bit...good luck
Do you have an idea for what ROM you like or want? Couple of great ROMs..for stockish check out flappjaxxx's for jellybean check out manelscout4life..stable and fast
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
Techno is onto the correct answer, unless of course you are truly wanting the stock version back.
Kies and OTA updates are often flawed, and give the end user exactly the type of problems you are stating.
However, if you want a return to stock, the information can be found in the "note super everything thread" located as a sticky at the top of the general note section.
But I do agree with techno, that a root and flash of a quality custom rom is the way to go......g
Thanks a lot, both of you!
As to what ROM I want, honestly that's one of the reasons I have been procrastinating so much -- I have no idea whatsoever. There's such an overwhelming number of options out there, of basic flavors (ICS, JB, GB, CM7, etc.) and tens of derivatives of each one made by different people. I have no idea where to even start making such a decision.
I can tell you this much. On my Atrix, I started with the stock Motoblur-Froyo, flashed GingerBlur, disliked it's bugginess but dealt with it for almost a year, then flashed the CM7-based Neutrino. I wasn't very happy with how skimpy the ROM was but stuck with it until I got my Note. I was pretty satiated with the stock ROM, but decided to upgrade to ICS due to the promise of a better UI, increased functionality and especially a faster camera. While my experience with ICS was terrible, I could see myself enjoying a functional, non-buggy version...
Basically, I have no idea what ROM or even what base OS version I am looking for. That said, I do know the criteria that matter to me, as stated prior:
Battery Life
Stability
Smooth UI
Cutting-Edge Feature Packed
I can't really think of any features I am specifically looking for, other than under-the-radar tethering and top-notch camera speed & functionality .
As I have no attachment to any specific OS version, suppose that would mean that if battery life, stability and smoothness issues are equal amongst ROM variants, I would be looking for a Jellybean ROM - as it would be most packed with new features... right?
http://forum.xda-developers.com/showthread.php?t=1664980
That is the best stockish ICS experience you can get and keeps all the functionality of your phone including the spen. He also offers a jellybean ROM but honestly to find the best JB rom for you just read through the threads read and REREAD THE OP of those ROMs..jellybean is fun and cool but not 101% stable yet..people still getting random reboots and some are losing there APN settings..so maybe just flashing ics and playing with those ROMs is best for you for now..FYI the above rom is smooth as silk and great battery life

Again , I agree with Techno, and the rom he posted is the one I'm using to type this.
Flappjaxxx is a fine developer, and he has packed this UCLF6 build with full functionality , and much more.
He is , and will continue to be my top pick for quality builds and performance ...g
This is all really wonderful advice - thanks again!
I guess I have a few last questions:
What is the best way to root at this point? If I recall, there are multiple ways to root via Odin... is there a specific one you would recommend for my current situation (read: current buggy ICS firmware)? A link would be very much appreciated, as the roadmap thread is a bit... overwhelming with all of the options.
Are there any MODs you recommend I install after I have my new flappjaxxx ROM in place? Will tethering work off the bat? Will all of the Gapps (Gmail, Navigation, etc.) be there for me to use? Will I need to install anything else, or is there any recommendations that you have?
Thanks again a ton - you've both been enormously helpful!
Also, I just noticed that the recovery you linked me to (http://teamw.in/project/twrp) has no option for the Galaxy Note...
EDIT: It turns out you linked me to the wrong page - to TWPR 1. Here's the link to TWRP 2.2, for anyone else who comes across this thread: http://teamw.in/project/twrp2
Just my 2 cents. After you get straightened out, you may want to take a look here.

AT&T Stock JB 4.1.2 - Slow, lagging, pros and cons

Moving back from a CM 10.1 based rom to stock once the new JB update was released by At&t, I knew there would be a slight sacrifice in speed when going back to the TouchWiz UI. I was willing to take that small hit to get the s-pen and other stuff back. I have noticed a few things about this update and I am on the fence as far as whether or not to stick with it or go back to a CM 10.1 based or other ROM:
Pros:
* The Nature UI on TouchWiz is pretty. The slight drop shadows under app icons and some widgets is nice.
* I like the S-Pen stuff, though to be honest, I don't use it all that often.
* The sound quality seems to be improved on this update. Not sure why, but everything sounds better - music, calls, notifications.
* This stock ROM seems to handle the screen colors better. There is less of that annoying AMOLED color banding effect that drives me nuts on most other ROMs (I am a web and graphics designer, so these aesthetic things bother me).
* Signal Quality - It seems the signal is stronger and I do like knowing the difference between a regular 4g and an LTE signal. It seems the modem firmware is also better (which I installed along with this update) and quicker at locking on to a data connection.
Cons:
* TouchWiz UI is really quite out of date when you consider all the advancements Google has made to Android since version 4.1 as far as grouping of icons, project butter etc. It seems that not much has improved overall on Samsung's TouchWiz since the previous update.
* My phone really lags as far as overall performance. Some of this is most likely due to TouchWiz, but opening apps, going to task manager and other processes is painfully slow and annoying. Forget trying to open the camera app in a pinch when you want to shoot a candid. By the time the camera is ready to shoot, the moment is gone.
* The leds under the menu buttons are not used for notifications - It seems silly to me that Samsung or At&t would not take advantage of this functionality that most third party ROMs do. If my phone is in a separate room on vibrate or mute and I receive a text or call, I will not know this until I actually pick up the phone and turn on the display. That is silly.
* Battery Life - sucks period. This seems worse with the update.
I guess what I am trying to do here is find a reason to stick with this update and perhaps make improvements based on others opinions here. I think the most important issue would be improving the speed/responsiveness of the system overall.
I have been following some of the other offerings available as far as third party ROMs based off the official Samsung/AT&T 4.1.2 version. Padawan is one such ROM which had quite a bit of attention in the forum.
There are some solutions which others have reported which make noticeable speed improvements in general:
* Deodexing - I think this is possible on a rooted device with a stock ROM, but most just install a ROM which is already deodexed. I wonder how much improvement in performance is noted after this is done.
* Debloating - Removing unnecessary apps that the carrier has decided to include to increase value to the customer. I am not sure what improvement in performance this really offers as to affect performance negatively, these apps would need to be running in the background all the time, right?
* Go with a vanilla generic Android ROM which does not have the TouchWiz UI over it, such as something CM based. As nice as the speed improvements are in doing that, I still would love to keep my s-pen sensitivity and features on the odd occasions when I do use the s-pen.
Anyhow, enough of my long winded post. I am just really curious as to what others think.

Thanks for your response. It was already rooted, running TWRP. As far as debloating, so would I use Titanium Backup to freeze or remove the at&t specific apps? Also which At&T bloatware causes the most issues in terms of performance lag? There may actually be one or two of those apps whose hit on performance is outweighed by their usefulness...

Well, then that's totally subjective. What I usually do is I freeze such apps. If you do really need them, you'll miss them. Then that's the indication you should unfreeze them.
I'm amazed at how hit-and-miss people's reviews of stock 4.1.2 are. I'm running true stock - in that I'm using the odin package - and it's the fastest, and by far the most stable, JB ROM I've ever used on my Note -- and I've run the gauntlet with them. I simply used ES File Explorer to delete everything that at all looked like something from AT&T, and then I went into my running applications/services, and anything that I did not use, or thought I didn't use, I went into Titanium and froze. Now I'm always at ~300mb of free RAM and my battery rivals anything I've experienced -- even a drastically underclocked and volted ICS kernel.
I did, however, accidentally delete my calculator in the process. I get a little aggressive with my cleaning of things. On the bright side, I found a CM calculator port on the market which is prettier and gets the job done.
I am running a stock rooted Rogers JB 4.1.2. It is by far faster, smoother, and better battery than the ICS counterpart. If I turned off Location services the battery would even be better.
I believe the problems most are experiencing is from dirty flashing. Format that USB storage and wipe the data before installing the ROM. I know from experience. I installed using odin without wiping or formatting anything. Yes I kept all my apps and info but what I was left with was a laggy and battery hungry phone.
I understand that the Quadrant test doesn't mirror real life but on my phone I constantly achieve higher test scores with stock 4.1.2 than with cm 10.1 or cm10.0.
Not saying I like it better or worse but I don't think speed is that bad on stock 4.1.2

I've been searching for a while, but obviously not good enough.
I've never rooted an Android phone and was hoping someone could point me in the right direction to root my AT&T JB updated i717 and replace it with the stock Android JB. I've had numerous problems with the stock AT&T JB (mainly Talkback launches on it's own, Wifi doesn't connect, Battery life sucks).
Thanks, in advance for any help and sorry for being a relative Newbie and asking what is an obvious question to most of you.

I suggest to do a full wipe data and cache. But be sure to backup your personal files as they Will be deleted. Try looking at how root videos on youtube to get an idea how to root. Heres one for an example: https://www.youtube.com/watch?v=Zpi8yCYJOt8&feature=youtube_gdata_player

Thank you !!! I've been watching a lot of them, but they don't seems to be exactly right. I really appreciate the feedback and help !!!
The thing I don't like about using any other ROMs, is that the "Auto Screen Tone Adjust" setting is not in any of them, and the screen automatically dims on white backgrounds and I don't like that. Is there a way to fix that or add the setting in another ROM?
