[LG Optimus L9 P760, P765, P768, P769] Elite.101:
No but i can do it, even tho i upgraded it to CM13 Android 6.0.1. CM13 has apns corrupted and media codecs too and supposedly some flashables would fix but i fixed com.android.phone crashing and unstable behavior with lag by uninstalling this system app aka Phone services and disabling phone and messaging storage, since this isnt my daily driver. But i guess ill try what you said.
[LG Optimus L9 P760, P765, P768, P769] KtuluTheSlayer:
Hi! I'm using this rom for a while and it works perfectly, except with any browsers I use, it freezes in certain pages, like this one or others like comicbookmovie.com, without reason, and sometimes other pages work fine, but sometimes they freeze too. I've tried a lot of options with kernel adiutor, and nothing works. And when I use the physical buttons, it takes a while to vibrate, meaning that it doesn't completely freeze.

I have used Chrome, Opera Mini and Firefox, but nothing works. Any help?
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Ram is overloaded. No future for this rom. CM13s zRam feature and swap file seem to care well for this issue. Going back to some older, smaller rom won't help either, as the apps and the web content are the culprits.
[LG Optimus L9 P760, P765, P768, P769] mirul_up:
:( [MENTION=6289357]EdwinMoq[/MENTION] please answer me, how to enable zram on this ROM? If its to complicated way just give me some explain.

Thanks before...
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Support for zram its not present on the kernel.
[LG Optimus L9 P760, P765, P768, P769] mirul_up:
:'( Oh god... Okay, thanks for your answer. Now I'll back to your cm13 again and waiting for your next update. I hope sdcard as internal on your cm13 like cm12 without formating or complicated steps. :D
[LG Optimus L9 P760, P765, P768, P769] samux14:
Can anyone tell me ,how can I make better the life of the battery ? I'm using cm 13 but I had this ROM but the battery is the same. Please :(
[LG Optimus L9 P760, P765, P768, P769] jes0411:
With the latest cm13 battery life is a lot better.

With this rom and previous cm13 is the same battery life, worse than latest cm13
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Battery life is not always bad. There are wakelocks in the wifi/bt chip which appear under circumstances that i couldn't reproduce and learn to avoid. And during use these wakelocks appeared more and more often, and not a simple restart would fix that, or a nandroid backup, but a clean rom install from time to time should help. Even during the last weeks of using CM12.1 i at least had phases where battery life, standby, idle and load, was normal. Just enough times to make sure the battery wasn't dying(which is only about a year old).
[LG Optimus L9 P760, P765, P768, P769] jccaguisa:
just a clarification, if i'm using p768, i will be flashing the one for P760 right? thank you for your response
[LG Optimus L9 P760, P765, P768, P769] sensirou:
Can I use this rom for my Lg P768?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Yes. Use the P760 version.
[LG Optimus L9 P760, P765, P768, P769] jccaguisa:
thank you. :)
[LG Optimus L9 P760, P765, P768, P769] jccaguisa:

[LG Optimus L9 P760, P765, P768, P769] sensirou:
Hi everyone, My device is P768 and I can't use link2sd to create link to SD card.

I have tried format with 2 type: -primary/fat32 + -primary/ext4 and primary/fat32+ primary/ext4 + primary/fat32 but it doest work. everytime I restart the phone, all apps are dissapeared.

please help me, this is the first time I use CM rom
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Why exactly are you using link2sd? This ROM comes with sdcard as internal by default, and you can move apps to SD from settings, so don't see the need to use link2sd.
[LG Optimus L9 P760, P765, P768, P769] sensirou:
thank you very much, and evertytime I restart phone, supersuser requires to update by using recovery mode. so what should I do?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
Well, cm comes with it's own SU binary. You just have to enable root from developer options. And you can manage root from From settings --> Privacy --> Privacy Guard. Probably Superuser is conflicting with the default SU binary.
[LG Optimus L9 P760, P765, P768, P769] jes0411:
Link2sd can move any app and can do it completely instead of moving only a part of it. And with paid version it can move app data too, useful for example with facebook app that uses too much space for data.

It worked well for me when using this rom with 2 partitions on sd, first primary fat32 and second primary ext4.
[LG Optimus L9 P760, P765, P768, P769] sensirou:
I used these 2 partitions too, but all apps will disappear when I reboot
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Wth emulated_sd disabled, data like caches from apps residing in the internal flash was stored on external sd. That way the free internal mem was shrinking slowly during use. Now the data of all non-moveable apps stays on the data partition and you have to clean up regularly. On my tablet with a similar setup, the whole stuff in emulated_sd still takes less than 100mb after clean-up, but can grow by several 100mb per day. And it's mostly tiny files generating much slack, making it worse.
[LG Optimus L9 P760, P765, P768, P769] DrGEROH:
Adding another data point here: I bought a P769 back in March 2013 to use on the pre-paid T-Mobile plan at the time. T-Mobile's LTE was poor in NW OH (or so I soon discovered), and went back to the Sprint-based Virgin Mobile after a few months of slow data. I didn't have device on the T-Mobile plan long enough to get it unlocked by them, but we managed to get it unlocked in Europe a couple summers ago (and since used it on pre-paid SIMs from Bouygues in France/Spain, ALDI TALK in Germany/Czech Republic, and Petro-Canada). I never cared much for LG's UI/skin, and performance of 4.1.2 was only fair, at best. And the process to unlock the bootloader was way too cumbersome for the benefit (considering the ease with which custom ROMs can be installed on my old Samsung devices). So when I came across this thread by chance (just yesterday!), I gave it a try.

I fetched the latest TRWP recovery IMG, CM12.1 ROM, and GApps ZIPs to a microSD card, installed [Root]Rashr from the Play Store, and followed this YouTube to root: (URL blocked, search for "How to root any phone- no pc").

After rooting successfully, [Root]Rashr installed the TRWP IMG & rebooted into the new TRWP recovery.

TRWP flashed both CM12.1 & Gapps ZIPs correctly.

And I can start the recovery successfully with Volume(-)+Home+Power, too.

Since then, I got a kernel panic while the device was idle (and without a SIM inserted).

I now have an old (expired) Petro-Canada SIM in it & we'll see how it goes, though my first impressions are that this custom ROM is OUTSTANDING ! Well done !
[LG Optimus L9 P760, P765, P768, P769] DarryDoo:
Any chance we can get the broken bluetooth in-call audio fixed on this ROM? It's not buggy like the 6.0.1 version, except for this one problem.
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
I'm going to upload a build with additions like zram when I can. CM12.1 is admittedly more stable than CM13.
[LG Optimus L9 P760, P765, P768, P769] bblq:
Great work and many thanks for your work so far.

Some observation for a P760.

I tried the build and hit a really strange problem with bluetooth - when I try to make a call with a bluetooth headset, all you can hear is some really loud noise.

Also, the overclocking makes the phone really hot + a I got kernel panic. After setting max cpu freq to 1008 MHz it worked OK.

The bluetooth somewhat works with dhiru1602 ROMs.

I would really like to change from the stock firmware, since I am experiencing problems with reception when travelling trough different countries and a constant hum is present when making a call. Non of that is present with Cyanogen mods =)

Anyway, please continue your great work and hope to be able to install a stable android 6 one day!
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Yeah, the basic BT function doesn't work, monaural headset. Other profiles, like audio streaming, work.
[LG Optimus L9 P760, P765, P768, P769] jccaguisa:
thank you for your continues support sir! if that build will be released, i will be using it instead of CM13. i think the battery consumption is better that cm13.
[LG Optimus L9 P760, P765, P768, P769] pkorets:
hello , can you please optimize the battery usage , because the phone is discharging too quickly , thanks !
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Well, GPS shouldn't be dead, but the situation is even worse on my P760, with CM12&13. GPS tries, but will never get a satfix, and the magnetic sensor is fully dead. You can then only determine the coarse location via network location service, and not the orientation, and not navigate, and map and nav apps may behave strangely, even with GPS deactivated, because of the dead sensors(3 out of 4 dead). Like a black screen until reboot and wakelocks draining battery.

But there should be few apps which are completely Google-independant. Most ones with location based features use the Google Maps Services, these are either part of the rom ot not. They will either need a Google account or at least a license(for the device) or not.

Google Maps works w/o the Google Maps Services, ironically.
[LG Optimus L9 P760, P765, P768, P769] DarryDoo:

Hay guys,

I got a big problem, yesterday I tryed to downgrade my brothers LG P760 and made a big misstake.

When I tryed to go into 'recovery mode', I just used the wrong keys (VOL DOWN + HOME + POWER ON/OFF). Now my phone doesn't boot up anymore, it just hangs at the LG bootlogo. I can go into 'S/W Mode' and into 'Fastboot Mode', but if I go into 'Fastboot Mode' my decive driver is hangs in a loop. Hanging all day and night to fix this problem, but I can't do anything.... I hope anyone can help me!

Windows OS: Windows 10

Phone: LG P760

ROM: CM 12.1

Thanks a lot!
[LG Optimus L9 P760, P765, P768, P769] DarryDoo:
What ROM before the downgrade? What were you trying to install?
[LG Optimus L9 P760, P765, P768, P769] d3nni:
I already had CM 12.1 installed and wanted to downgrade to CM 11, but I used wrong keys (I used VOL DOWN insted of VOL UP) to go into recovery mode and suddenly the phone was not booting up anymore.

Thanks mate! :)
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
That was the right key combo, but a strange issue which plagued me, too.

With TWRP 2.8.x, it's gone with current TWRP. You still could have booted to TWRP from within Android, but now it's unbrick time in D/L mode. And use the latest Twrp this time.
[LG Optimus L9 P760, P765, P768, P769] d3nni:
It seems that you had exactly the same problem as me. I also had TWRP 2.8.x on my phone. And I already asked myself why it didn't happen the 2 times I already enterd the recovery. It might happen cuz I used Titanium Backup before to enter the recovery mode. This is the first time I used the key combo and "GOSH".... I broke the phone of my brother and I feel so bad, he can't use his phone for almost 2 days now and I hang 24/7 to fix it. Damn it!! :(

I don't know how to enter the D/L mode, can you help me? Can I use Odin witht the D/L mode, or what should I do?
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
LG's recovery tool, which will provide drivers and Firmware online.

I once more forgot whether to press Vol+ or Vol- while attaching the phone, which has to be switched off fir this. Phone will power on after several seconds and D/L mode screen appear, otherwise force power off, for added reliability switch phone on and force off again, then try D/L mode again.

Root with the Kango tool, download Flashify or Rashr on the phone, install Twrp.

It will be easier and quicker, if Fastboot mode works. Then install Twrp directly via ADB/Fastboot once the stock rom is installed.
[LG Optimus L9 P760, P765, P768, P769] d3nni:
You mean the "LG Mobile Support Tool"? I tryed to use it and finnaly I came to the flashing point. He first downloaded the software and while it was downloading the phone just shut down. I toke it back into S/W Mode and pressed 'try again'.... then he was flashing and the phone just shutted down again. Why is he always shutting down after like 2~3 minutes?

Still sitting here.... :(

EDIT: The 'LG Mobile Support Tool' says that the right firmeware is already installed and then he is starting to download V20O with 599,15MByte. But the thing is, that the phone will just go out of the S/W mode while the 'LG Mobile Support Tool' is downloading the V20O. After the phone switched off, my driver is looping and always saying it can't recnogrize it. It does it like 20 times and then the phone will go on and LG logo appears. Nothing more.... :/

[MENTION=6289357]EdwinMoq[/MENTION] Does kernel include full zram support ?

Edit:

I see there's /sys/block/zram0 ,but there device isn't initialized at /dev/zram0 ,I can't choose algorithm in /sys/block/zram0 ,and there's no /sys/class/zram-control ,so I can't "hot_add" /dev/zram0

This ROM doesn't contain Zram support. Edwin said he was going to add it, but he's been absent from the forums.

Battery

I love this rom, but my battery drains all in two hours. Change the frequency to 600 MHz and the problem continues. Any suggestions ?
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
The L9s default clocks are 0,2 to 1Ghz. This kernel is set to 0,3 or 0,4 and 1,35ghz. That's where the trouble starts. Up to 1,2ghz the battery consumption stays moderate, but even at 1,35 you hardly notice any performance benefits. 4 cores at 2,3ghz or 8 at 1,5ghz, THAT makes a real difference!

Even if the clocks are modified with Kernel Adiutor or 3C Android Toolkit, often(but not always) power consumption is excessive, and there aren't even any notable wakelocks, like the wifi bug of CM12.1. (Edit: Oops, this IS 12.1. Wakelock Detector may show the wifi drain. But I also had occasional standby and idle drain with 12.1, mostly when out and around. About 1%/min, so a full battery would drain in 1,5h. Usage of wifi prevented it somehow.)

But during a freeze or crash (also not uncommon) part of the battery log gets lost, and the total power up or screen on time displayed is shorter than in reality. This can happen with all Android versions and devices.

solution for battery discharge

I found the solution for battery discharge is make undervolting. excellent performance, took 8 hours to 3 hours on the screen on and still have 30% battery
[LG Optimus L9 P760, P765, P768, P769] vandal94:
Can you explain bit more man, can you tell the voltage values please or take pic of your settings.
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
Underclocking results in undervolting. But probably you can also vary voltages a bit(depends on the device). But it has to be done for each clock stage.
[LG Optimus L9 P760, P765, P768, P769] pab201:

[LG Optimus L9 P760, P765, P768, P769] pab201:

Buenos días, instale esta rom y esta genial peroo no conecta a ningún wifi, existe alguna solución a este problema?????
[LG Optimus L9 P760, P765, P768, P769] facuarmo:
Hey, thanks for posting your setup. Anyways, I've noticed that many apps started to crash as a result of faulty maths from the processor. I've added +10mv to mine and it worked flawlessly ;). Just for info if someone is experiencing the same behavior.
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
It may be because this ROM uses F2FS. Try to enable f2fs in TWRP options and wiping System, Data, cache and Dalvik cache. I don't think that's the problem, but it doesn't hurt to try.
[LG Optimus L9 P760, P765, P768, P769] optimus l9:
Did you try using gps fixer by artas. I don't know whether its compatible with this rom but it worked with cm 11.

[LG Optimus L9 P760, P765, P768, P769] joselap:

---------- Post added at 11:56 AM ---------- Previous post was at 11:44 AM ----------

The version of the recovery twrp.img available for this rom, which is it?

---------- Post added at 12:33 PM ---------- Previous post was at 11:56 AM ----------

Hey guys!!! Please, nobody knows? none of you has flashed the twrp.img for this rom?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
The reason I didn't indicate to wipe with f2fs is because there was no need to. This ROM uses cache and data pre-omptimization so when you install it the old data gets overwritten and the filesystem is replaced. At least I though it wasn't necessary.
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
I'm sorry. I thout it was using f2fs. But for some reason it's using ext4, even though I set to use f2fs in my device tree. Sorry for the inconveniences, I'll try to look at it.
[LG Optimus L9 P760, P765, P768, P769] ippon:

Edwin, you are my hero.

gonna tinker around with this.

has anyone been able to OC the P769?
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
The ROM is overclocked by default. Download Kernel Auditor from the playstore and use settings best suits you. On my P769 I use Interactive governor with 1200mhz max.
[LG Optimus L9 P760, P765, P768, P769] ippon:
My p769 crashes when I try to oc.

Not a big deal though.

Would be fantastic to get the front camera working soon. Once that's done, it will be my daily driver.
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
The ROM is overclocked to 1.3ghz by default. If it does boot then it support overclocking. Which settings did you try? You can set it at 1.0ghz which is the default clock speed to see if it works.
[LG Optimus L9 P760, P765, P768, P769] EdwinMoq:
New build is up! I messed media codecs trying to fix the camera and now media recording is broken. But front camera works now and I will fix media codecs ASAP. Vibrator is working too.

For those having issues with SuperSu I recommend to use Privacy Guard. It allows you to manage different permissions of apps, including root access. Enable root in developers options and use Privacy Guard to manage root access. It works great for me.

Next build with fixed media codecs will be up later.

I don't know much about the p768, but in the vendor blobs I found that only one file is replaced, the ducati_m3.bin, so I don't see why the patch wouldn't work with this ROM... But remember that the camera is not fully functional yet, not even on p760/p769.
