Remember if you wanna using ART you will use more memory, but device feels better in compare with dalvik...

How you can activate ART:

- tap build number over and over until it says you are a developer and it back

- tap on developer options that just appeared above about phone and turn them on (if it ins't already)

- search for select runtime and tap on that

- now select use ART and tab ok

- you phone will reboot now itself (if not, reboot it by yourself)
[LG Optimus 2x] May.Assem:
Unfortunately, that solution didn't work out as I was hoping. ART slowed the device down to a crawl. I had to revert back to dalvik. :/
[LG Optimus 2x] tonyp:
So the general consent seems to be that the new memory settings do not work better than the custom option I had included, correct?

Then I will bring the option back, I just removed it so no one gets confused while testing around.

I'm planning one last and final update to my sources.

I think CM will release another M build this year. If that's the case I'll merge it into my sources, after that someone else has to fork my code to completely take over.

I still think lollipop will be possible to port, timduru already released it for the tf101 tegra2 tablet. I hope someone steps up to try and push the bounds of our beloved device even further :)

I think in this case I would just use an LG Stock ICS ROM.
[LG Optimus 2x] vanko11595:
First of all thanx for your great work.

Could you include in this update the fix for wifi tethering from the previous 3.1 build (cm-11-20141024-UNOFFICIAL-p990.3.1.zip). Because in the last build (cm-11-20141114-UNOFFICIAL-p990.3.1.zip) wifi tethering do not work (can't start).
[LG Optimus 2x] kennyFF92:
For me last M12 isn't different from M11 with tonyp's memory optimizations, it works the same.
[LG Optimus 2x] Hugo-PT:
Well, in my case (M1), the phone behavior, slightly improved. Everything works great! ..Is more smoother, faster, and better performance, compared to the previous version.

What I see, less positive, is the battery consumption, but I do not mind!

Very happy to know yours future intentions! ..One last time. Thanks :D

Also grateful for your opinion on the possibility of a lollipop to our phone. :)

Thanks so much, Great tonyp

Best regards,

Hugo

Edit: I forgot to mention, that in AnTuTu, improved my results, compared with the previous build :D

rofl this hit the news: htc phone with 0.60GHz cpu gets cm12 running

so eeh... for cm12 on o2x.. you use the device tree of p990 from tonyp, add cm12 sources, compile, flash it and then start dropping logcats + debugging until it boots?

how da heck did tonyp get us from ics to jb to kk anyway? whats your secret
[LG Optimus 2x] tonyp:
Well, that's pretty much how you do it. You research a lot what needs to be changed, compile a ton of testbuilds and try to understand what's failing in the logs (if you already managed to bring it into a state where you're able to get logs, which took quite some time back for CM10.2).

Luckily Android is mostly open source, so you can check what others did and compare - but of course each device differs in various parts.

The most important thing you need is dedication. When I started I had no idea about Android, I just gave it a shot and tried to learn on the go.

With the time you get some experience which helps you to track down bugs and understand better how everything is related.

But my skills have never been near the ones of people like [MENTION=2330281]aremcee[/MENTION], without him we wouldn't have the CM base that everything has been build on.

Of course there have been a lot more people who have contributed and without whom we wouldn't be anywhere near the current status - but I don't want to start naming some as I don't want to miss anyone.

Ok, great. Than I will bring back the option in the memory settings, so people can choose whatever suits them best (or use PerformanceControl to adjust everything even further).

I didn't remove anything, so I can't explain why it stopped working...

Initial experience with CM11 & 3.1.10 Kernel

I had been using TonyP's The ROM build 26 with M1 kernel all this while and was very happy with the feature set and stability.

Yesterday I tried CM11 build form 1st june and M1 kernel after complete wipe and didnot restore any settings or apps using Titanium backup, It was stable but Wifi hotspot wasnot working. Hence didnot see any benefits as I dont use Camera a lot.

So finally moved to CM11 build from 27th May & Firtecy kernel with 32MB Ram hack. Again complete wipe, and didnot restore any settings or apps. So these are what I noticed in intial 12 hours.

Bugs:

1. Loosing mobile network frequently. Have taken the logs using Syslog, will attach it once I am on my PC. Figured out, this was a problem from my mobile operator. Nothing to do with the ROM. Hence, logs not needed here.

2. I think 'In call UI' bug is back again. The patch might have been missed. Phone takes about 5 seconds to show call UI after receiving call. It was fixed in Jan build by Tony.

3. Performance settings like CPU OC and other setting do not stick after reebot. Will try app link provided by ivaneris and report. (I wonder if logs will be useful as the issue cmes after reboot)

What I am missing after the upgrade: (All THE ROM features :p )

1. DPI changer - specially for apps like Youtube, Google Keep, Calender & Browser.

2. Location toggle in quick tiles

3. Ram bar in recent apps list.

4. Gesture unlock

5. LG Quick Memo

Good things: :laugh:

1. Fluid - Comparable to CM10.2 The ROM

2. Idle battery consumption is very low. Specially WIFi battery consumption for me.

3. Loving the new UI and transclusent bar, and the feeling of latest Android

4. Double tap the translusent bar to sleep

5. New theme engine

Thanks TonyP, BS86 & Firtecy. Keep up the good work. I was about to move to a new phone in Jan 2013, and 1.5 years later I am happy with it and might use it for another 6 months or a year.
[LG Optimus 2x] Supreme_One:
Wi-Fi optimization should it be enabled or disabled? It says minimize battery usage. So it saves battery? Or causes WiFi optimization battery drain?
[LG Optimus 2x] Surplus:
If you're using bcm4329 build, leave it disabled as it's not supported. Use the power management options in Kowalski Manager instead.

If you're using a 3.1 kernel build, you can enable it.

Also, please read what others have posted, I'm quite sure TonyP already covered this earlier.
[LG Optimus 2x] amarprat87:
Enable it for 3.1.10 kernel

Disable it for 2.6.39 M1 kernel, use wifi optimizations (first 3) in kowalski manager

Sorry for OT, but its even getting to my nerves and I am just a user.
[LG Optimus 2x] AndroAndroxda:
Yes, I tried it several times. I did a Full Wipe, Wipe Cache, Wipe Dalvik, Format / System Format sdcard.

Now it is the same times without me 3G/Wifi enabled networks :(

Namely, that it started to do it with my old version of CM11 Tony (20140120).

This battery would it?

Thank you in advance.
[LG Optimus 2x] BS86:
sorry, missed them - will try to take a look after the weekend - until then I won't have time

then I guess you should stick with bcmdhd - thats why we offer 2 builds

I guess the last step you could do is flashing your baseband again (http://xdaforums.com/showthread.php?t=1658047) with the Erase CP option activated and being prepared to restore your IMEI with a 2.3 android version:

http://xdaforums.com/showpost.php?p=20815755&postcount=26

and then changing back to newbl with updating to ICS

after that your phone should be back to first delivery standard. If the problems still exist, it is most likely a hardware fault
[LG Optimus 2x] BlueRazor:
Hi and thank you very much for your work guys. You saved who can't afford to buy a new phone. I've done a fresh install of the 27/05 build and it looks very smooth for our old device.

After 3 days I have to report a few bugs:

- I have the Caller UI delay bug too. The screen stays black and takes around 5 seconds to show who's calling. This is the only true annoying bug found.

- Sometimes opening apps like facebook or skype the screen goes black for a while until the app is fully loaded, which takes way longer than in February build.

- Some wifi crash that needs reboot, but it should be kernel related cause I always had in Kovalski alpha 31

---------- Post added at 12:53 PM ---------- Previous post was at 12:44 PM ----------

You can do #1 with one of the apps you can find in Play Store and #3 installing GravityBox.

Never used others so I can't say.

The ROM features were great but times move on and we should be thankful for having KK now! :D

2.2 - 2.3 - 4.0 - 4.1 - 4.2 - 4.3 -4.4... are 6 Android different versions available. What phone can do better? :D:D:D
[LG Optimus 2x] vanko11595:
Wifi tethering is not working for me with M1 build (20140601), but bluetooth music is just fine. I listen spotify through bluetooth headset and docking station for about an hour and no problems.

edit: anybody noticed that there are no arrows, which indicate traffic over wi-fi or mobile data.
[LG Optimus 2x] Hugo-PT:
2 days after installing this ROM, I have to say that I am very happy with this version! :cool:

Performance, stability and smoothness, is what gives me. Obviously the issues previously reported by tonyp, are present in the version I'm using, but those who want the latest releases .. have to live with what is offered to them by now. ;)

great!!!i really don't understand people who said you're lazy...just ignore it.....they just to lazy...:thumbup::thumbup::thumbup:

i don't think it's the same bug...it's simply because our phone had a very low ram (by now)

My suggestion

1. Use firtecy modified kowalski 32rh very good for memory boost

2. When using zram/swap eventually device will get lag (due to difference speed of actual ram and virtual one) in call ui will get lag too..happen to me also...and i suggest to use aggresive or very aggressive lmk (provided by performance control app and stock performance settings) in my case..i have ~160 active app include system greenified most of them (leave just bbm,whatsapp,mail,and some others) and using very aggresive lmk with modifying 2 last value...see this

View attachment 2780353

Well...it's not instantly..but in call ui just get a little lag (considering my active app)...maybe you can try it

It's has been said...it got the same bug as cm10.2 with m1..please read op ;)

That's strange then...wich recovery you're using?i recommend to flash twrp 2.6.0...i guess that's recovery fault...

[LG Optimus 2x] mrjeff:
If you are refering to this rom, http://www21.zippyshare.com/v/59861917/file.html, I dont know although this version is radically slimmed down in order to fit into a 200 meg zip. If you know exactly the bare minimum files for running Play then give it a go, as I said the rom is very slim and should have some headroom to play around with.

The rom itself runs OK but

- has much worse battery consumption than i.e. TheROM build 26

- video playback does not work in the browser

- the dialer is very buggy

- suspicious random crashes in other apps

plus the usual caveats with HDMI, bluetooth and wifi.

But its a quite snappy rom with some nice features.

Not much of a help but maybe you could give it a go and share your results.

RAM improvement

I found one more way to improve the ram management on our phone. The "free" ram is in general not free, only a small part of it. The rest is used to cache apps. Those aren't shown in the "taskmanager". With this app: https://play.google.com/store/apps/details?id=mem.usage&hl=de you can see all apps that are in the ram. I also found out that there were at every time several apps in it that (at least) I never use, like Whisper Push.

If you found some stuff you don't want, I'd recommend to go in Performance Control and then there should be something like "deactivate applications". Just deactivate the ones you don't want. They will dissapear in the launcher, but you can reactivate them at any time.

I deactivated Barcode Scanner, Pico TTS (it is used for Text To Speech, which I don't use), Voicedialer (I hope it's called that way in English), Apollo, Camera2, CMFileManagerm, DSPManager, VoicePlus, Whisper Push. Those applications were cached on my device, but there was no use, since I never used those apps.

I'm sure some of you use some of these applications, but if you use an alternative and don't need the other one, I'd deactivate it. You can also deinstall those apps by deleting them from #/system/app. I get a lot of free ram, about 130-150mb when no apps are running. Android starts to cache other applications now, which I use more regulary. You can change your minfree values, so you make more use of all that ram :D

Since our device has a unused Swap-partition (on new bootloader), why shouldn't we use it? This tutorial by Raum1807 http://xdaforums.com/showthread.php?t=2100058 tells you how. You should deactivate z-ram if you want to use it. Do so by deleting the 03_zram_tonyp data, which is located... somewhere. I used a swapiness of about 10, you can set that in Performance Control.

Also, deleting cache and dalvik cache (-> Performance Control) did also improve the performance a lot.

I hope this helps someone, it helped myself very much. If someone knows how to improve this even more, tell me :)

After I got very valuable info about NEON and potential issues on out tegra2 SOC system from [MENTION=3605868]tonyp[/MENTION] here I no longer suspect that NEON issues could be the reason for lag in CM11 (or other ROMs).

Thanks a lot lulli1! This CM11 is much less laggy. I use it as a daily driver at the moment.

echo_21
[LG Optimus 2x] echo_21:
Is there at least one CM11 ROM with "high performance" ?

Would you like to clarify what you mean with the term "performance"?

Performance for me means (1) no lag in GUI of current app in foreground, (2) task switch to a previously started app (started at least once after last boot) must be to an instance in cache instead of a new start of that app, and (3) first start of an app after last reboot as quick as possible.

I wonder why the 2 CM11 versions I tested since autum 2014 are never reliably able to fulfill all 3 requirements at the same time.

1. Kernel 2.6 m1 CM11 M12 "pure tonyp" 2014/11/13 released by [MENTION=5021221]gucky01[/MENTION] : huge lag even when no additional apps installed -> requirement (1) not fulfilled

2. Edit: Kernel 2.6 m1 CM11 M11 "justarchi" 2014/10/23 Kernel 2.6 m1 CM11 M11 "justarchi" 2014/10/13 released by [MENTION=5021221]gucky01[/MENTION] (I use this as my daily driver at the moment): very little lag but after 36 hours after boot free memory decreases to 70MB (memory leaks?); the P990 gets laggier (1) and fast task switch does not work anymore (2)

Who else uses one of these 2 versions as a daily driver? What is your experience?

Who uses which other CM11 version as a daily driver and can say that all 3 requirments are fulfilled?

Kitkat (Android 4.4; CM 11) was reprogrammed by Google to improve user experience on low RAM devices like or 500 MB RAM P990 2x. It seems to me that these improvements are somewhat successful as at least in the amount of free RAM shown in Settings|Apps|Active is around 130 MB instead of the 50 MB on the CM10.2 of my wife's P990. What I don't understand: Why does my wife's P990 works with high performance ((1)+(2)+(3)) even if it's CM10.2 has not been optimized for low RAM? (We accept that she has to reboot her P990 once every 10 days, as memory gets low than and lag starts (1) as well as task switch gets slow (2) )

Are all existing CM11 releases worse in "total performance" (aka "user experience") than the best CM10.2 release?

Thanks for your efforts sharing this all with us. But I don't understand why this tweaking is ever necessary on CM11 (see above) to make it performing acceptably. CM10.2 has great performance even if it has not been optimized for low memory consumption.
