Hi community,

I've spoke with Grarak, the developer of the Kitkat compatible Kernel (http://xdaforums.com/showthread.php?t=2405306&page=10) for the Samsung Galaxy R (same CPU, GPU, etc. as our LG P990) if he would help us by adapting his Kernel to our phone.

He would help, if he has a LG P990 to develop.

My question: does anyone here has an old LG P990 that can donate it to Grarak, like we did sometime ago with Pengus77?

Maybe someone that already move on to another phone and does not use the LG P990 anymore? :)

I think this guy is our last hope for a successful Kitkat on our lovely LG P990! :)

Hope someone is kindly enough to help our community...

Greetings to all... and thanks for all the work already done by our developers!

Mike

Is explained how to use unofficial source?I mean,i need to download first all the source code from cyanogenmod repo,and after sync with the tonyp's sources?if yes,how?
[LG Optimus 2x] sokinso:
So I installed topntp app patched the configuration and restarted.Also I enabled google location report then tested with GPS test app and got a fix within 3 minutes.it seemed to lock instantly then on google maps even I restarted my phone 3 times so I think topntp app did the job.

Now I am playing with ram settings to find the golden spot.

Thanks guys.
[LG Optimus 2x] Firtecy:
You just have to use another manifest so you should run the following:

repo init -u https://github.com/tonyp/android_manifest -b cm-11.0-tonyp

And that should be all :)

For all other you should take a look at http://xdaforums.com/showthread.php?t=2515305

But you do not have to run this command:

breakfast mako

And the two after that one

And when you run brunch you should use the codename for our device, so don't use brunch make, but use brunch p990

I've a strange problem. When I flash the latest version of this ROM without installing the KK 3.1 everything seems working normal, despite the battery drain. When I flash the KK 3.1 after flashing the ROM my phone freezes continuously. The strange thing is after doing a full wipe and flash of this ROM KK is already flashed I can see it in the menu. When I afterwards flash KK 3.1 the phones freezes after a couple of minutes. What should I do and how can I completely remove the KK 3.1 because doing a full wipe doesnt remove KK 3.1 Will the latest version of this ROM work also with an older version of KK ?
[LG Optimus 2x] soulripper24:
For me this happens too... If i update kernel my phone freezes. The solution? Not install kernel 3.1 :( I´m with kitkat with native kernel ( kk 28 )
[LG Optimus 2x] pijas82:
hello friend, you ever installed the ROM cnblack? I think the problem is that, because my friend soulripper was left alone with this problem, after installing the ROM cnblack.
[LG Optimus 2x] soulripper24:
Hi great Diogo :) Wasn´t with cnblack but slimrom... After install the latest slimrom, this problem starts...
[LG Optimus 2x] Supreme_One:
Never installed the ROM of cnblack, neither installed slimrom.

---------- Post added at 12:21 AM ---------- Previous post was at 12:16 AM ----------

So you installed afterwards KK 28? So what I need to do is first do a full wipe than flash cm-11-20140217-UNOFFICIAL-p990.zip and then flash KK 28? Or can I flash KK28 without doing a full wipe?

Where can I download KK 28 btw ?
[LG Optimus 2x] soulripper24:
I´m sorry, i´m meant that i was not able to install kernel alpha 31, i`ve just installed cm11-2014-02-17 without install any kernel further... I thought that the kernel in this date rom was kk 28.

Hey guys, there's something interesting here (only for ROM builders) :) http://xdaforums.com/showthread.php?t=2754997

[LG Optimus 2x] tonyp:
Not really interesting for our device. Most of those optimizations will result in bigger binaries which occupy more RAM.

In fact, in my build I'm even going the opposite way:

Instead of changing -Os to -O2 for THUMB, I'm even changing -O2 to -Os for ARM, to get even a bit more free RAM.

(I did some public testing a while ago with two builds and most people preferred this option).

I added support for that in my build repo here: https://github.com/tonyp/android_build/commit/25cec57fcbbc50619e3cb84d02d8aced847112e1

I've invented the TARGET_USE_OS flag to enable it, which is set by default in my device tree.

GCC 4.8 might be worth a try on CM11, if you use my build repo I added support for those quite some time ago (https://github.com/tonyp/android_build/commit/f67b8334c3d696ed863da238448675546167984b), so you're good to go.

Some other flags and changes from that project might be interesting, but the performance improvement is probably neglactable.

Okay, you have to go in the catlog app, then open the options menu. Click on the entry "Save" (or how it is called in your language of choice). Type in a name you will remember.

Afterwards open a file manager and go to /sdcard/catlog/saved_logs/ and find the file with the name you typed in. You have to upload that file as attachment in here :)

Make sure that CPU frequency has not been set to higher frequencies than 1000MHz. To me it happened that OC has unintentionally been set to 1500MHz with subsequent freezes. I can't remember if it was in Kowalski Manager or Performance Control or or or .
[LG Optimus 2x] Supreme_One:
It's all default. Nevertheless I'm using it without flashing the KK 3.1. Another interesting thing when I open battery calibration app I see without KK 3.1 only 1 number like 4 mv and with KK flashed it says 4172 mv 4168 mv when fully charged. Also when I open KK panel I see at the bottom that 3.1 is flashed while I didn't flash it separatly.
[LG Optimus 2x] BS86:
a very old version of the 3.1 kernel is preinstalled (something like 3.1.10 alpha18 or so) - now we are at alpha31 with a lot of bugfixes and improvements. Therefore I would strongly recommend flashing 3.1.10 alpha31 over it. M1 is not compatible with this ROM, wifi will not work.
[LG Optimus 2x] Supreme_One:
When I flash the latest. My phone freezes subsequently. I'm good with this version till something stable will come out.

go to performance settings and check the maximum frequency after flashing alpha31 - set it to 1000MHz

I will try out later. I dont have now time to flash. Thank you!

Hi best people , news? ;)

[LG Optimus 2x] tonyp:
The thing with asking about news is it's kind of like asking about an ETA.

If there are good news we'll write about them - if not, there are no news.

The last build was too buggy to release, with hot reboots and black screens.

CM fixed a couple bugs upstream, so a new testbuild by [MENTION=5124291]Firtecy[/MENTION] might work better now.

Unfortunately I still don't have access to a buildserver, I got in contact with basketbuild who offer a buildserver (or at least a frontend, no shell access).

They granted me beta access, but it didn't work properly so far.

Despite me releasing all the sources and a couple people forking them or announcing a build, I don't see anyone besides [MENTION=5124291]Firtecy[/MENTION] helping out, yet.

As long as this is the case all you can do is wait until [MENTION=5124291]Firtecy[/MENTION] or I make progress and post about it here.

I do think that a new build should drop "soon" (which can be anything between 2 days and 2 month, depending on the amount of free time and building capabilities).

But as I'm already posting, the OP is terribly outdated and it doesn't look like [MENTION=4640273]Fíghter02[/MENTION] is going to update it - anyone here interested in taking over? Then I'll make that happen.

it still lacks proper zRAM support (performance control does it)

and it seems to hang at the keyguard at boot - but if it is given some time to finish booting, it behaves like it should ;)

still want to test it further, and tonyp and firtecy might also publish soon - therefore my build will be obsolete

but for the future, if no other dev has time, I can always try to build from newest cm-sources ;)

[LG Optimus 2x] Firtecy:
I would say you mustn't wait for longer :P

A new build is up. It is from the codebase of the 23. May. So it includes a newer CyanogenMod version. That means newer projects, like the new theme engine, are included as well.

But at the moment it seems like zram is broken.

Update: Zram is fixed if you use the kernel that I provided some posts after this one

And keep in mind that a full wipe is recommended. I have dirty flashed it over the last build from tonyp and i had many problems. So if you have problems in any kind and have not made a full wipe, make one.

Keep in mind, that when you have issues and made a full wipe, to report them include a log!

So no log = no issue

Have fun!

http://tonyp.basketbuild.com/index.php?dir=main/CM-11.0/

tonyp will write later something about the changelog
[LG Optimus 2x] tonyp:
Finally here's the new build :)

As Firtecy wrote, the biggest change is probably the CM codebase update, which is a bit newer than M6 (everything that was in the stable/cm-11.0 branch two days ago).

Then I've enabled the transparent statusbar without the need to mess with the build.prop. Additionally it enables the fadeout effect when pulling down the statusbar.

Thanks for this goes to htto@github: https://gist.github.com/htto/9849712

If you want to disable that open the terminal and type the following command and do a reboot

su
setprop persist.sys.force_transbar false

(or change/delete the "persist.sys.force_transbar=true" line in the build.prop, but I'd recommend the first method, as it's safer and survives a rom update).

Note that changing the low_ram property has negative side effects, as apps stop using low_ram states (when available).

For those of you who'd like to keep using highend gfx graphics in the entire system there's a new option in Settings - Performance - Advanced Settings.

It will enable all the high end visual effects the removal of the low_ram line enabled, not just the statusbar transparency and fadeout effect (but I don't see a need to enable it, it will use more ram and increase lags).

Then the Kowalski kernl (to kk31), Google Apps package and the BarcodeScanner app were updated.

The SetupWizard got removed due to it's incompatibilities (you can just add the Google account via Settings).

Same goes for the (previously non working) QuickMemo support, this will come back when someone decompiles and fixes the QuickMemo apk for CM11.

Last but not least there were a couple improvements and updates in the code by [MENTION=5600347]hjunii[/MENTION], [MENTION=5124291]Firtecy[/MENTION] and myself, mainly in the device tree.

Regarding zram, as some of you might know, CM removed their old zram support a while back:

http://review.cyanogenmod.org/#/c/56874/

http://review.cyanogenmod.org/#/c/56875/

Google introduced native zram support to kitkat, unfortunately something went wrong with enabling it in CM11 for the 2x.

We hope that we can fix it in the short-term, but didn't want to hold back the ROM any longer as it's been quite some time since the last release and apart from that in our limited testing everything worked fine.

Update: the short term was shorter than expected, the ROM side is fine, it was a lack of support in the kernel. A new kernel with zram support will be provided soon :)

Enjoy, and remember to post logs for non-known problems (read: do not post about the camera).
[LG Optimus 2x] pijas82:
hi

AMAZING ROM

thanks, OMG :)
[LG Optimus 2x] lukino993:
thanks for your work guys :)
[LG Optimus 2x] Firtecy:
Second update for today:

After some researches mostly from [MENTION=3605868]tonyp[/MENTION] and a hint from [MENTION=5600347]hjunii[/MENTION], we found the cause for the zram problems. It was a kernel fault.

I have rebuild the kernel with the change in my personal kernel builds. I will post it in here so people can still use zram. And zram makes a lot of difference, at least for me.

Notice: This is my personal build. It is based on kowalski kernel so thanks to [MENTION=3783116]pengus77[/MENTION] for the base. It contains some minor bug fixes (no camera fix!) and other additions. I can not guarantee that it is as stable as the original kowalski kernel. It can be more stable, but maybe also not. So test it at your own risk!

Download:

Update: Link removed as it was causing problems(read: http://xdaforums.com/showthread.php?p=52929827#post52929827)

The zip is modified, so maybe you have to toggle of zip file verification!

Since the linux kernel is released under GPL here is the link to the source code:
