Ok, after some more investigation i think i just found that Kernel does have NFC module, if i look into /dev/ with: ls -l /dev/ i will find:

crw------- root root 10, 37 2015-05-19 10:38 network_latency
crw------- root root 10, 36 2015-05-19 10:38 network_throughput
crw-rw-rw- root root 1, 3 2015-05-19 10:38 null
[B]crw------- nfc nfc 10, 53 2015-05-19 10:38 pn544[/B]
crw-rw---- radio vpn 108, 0 2015-05-19 10:38 ppp
crw------- root root 10, 1 2015-05-19 10:38 psaux

Where i can read pn544 that is our p760 NFC chip.

I just tried to get the needed NFC files from other CM 12.1 (Android 5.1.1) roms and put it into your rom, but unfortunately this doesn't worked, but in some chases there were some progress.

Files taken from Nexus 5 CM 12.1 (different NFC chip): ----> I can see NFC toggle inside Android Settings, applications that make use of NFC see that it is disabled, but it wan't turn on unfortunately

View attachment MY_NFC_Enabler.zip

Files taken from Nexus 7 CM 12.1 (same NFC chip as our p760): ----> I can't see NFC toggle inside Android Settings at all

View attachment MY_NFC_Enabler_NEW.zip

So i think that the solution with Nexus 5 files is the one that is closer to the solution, but for some reason doesn't works....

ATM i have no time to investigate more and make some other tests, but i hope this will be usefull to someone that have time to spend to make NFC works on p760

EDIT:

This is the log with the errors generated with the Nexus 5 files:

I'm still with Artas' Rom, but this one seems to have the same 3G troubles as his, which can be cured by using thr right baseband firmware. For Artas' rom it's the latest v20o or p. Which should I use here?

I flashed the bb with Artas' hacked LG flash tool, which conly contains the baseband firmware, not a complete rom. Anything else might no longer work, as an L9 with Artas CM11 gets no longer recognized by the LG usb drivers and software, except in download mode. This sufficed for the hacked tool, but probably not the regular flash tool.
[LG Optimus L9 P760, P765, P768, P769] cheppiroma:
Im also having network issue before. When i flash rammar PA 4.6. I ask everywhere and the answer is yes should flash the baseband. But i found it hard to update though (with artas method, or flashing the kdz). And i dont really know why.

At first i almost desperate about that, and decided not using CM 11 version or up just use CM 10. And then i found master Imer thread. Since it was the same model (P765), i then decided to try flashing newer rom again.

After flashing, the network issue still come. And then i read again carefully the requirement for the rom. I found that my recovery still using CWM 6.0.4.8, i try to change the recovery to TWRP suggested. After flashing recovery, and the rom. The network issue seems fixed, just one or two time my device lost signal, but not long it back again without reboot the phone.

So i may think its not always because baseband, maybe other like recovery.. But its just my tought, i may wrong too.. Anyone?

Sorry for my bad english and the long story, just sharing ;)

Try install Facebook Lite, its smaller and snappier than the main Facebook App. Though it don't have lot feature, but the main function is good. And it wouldn't bother you with lag. Hope it helps ;)

Ok guys. Rom is good but I've found that the only way to make lollipop usable on our device is either installing few selected apps or hibernate the heavy ones such as facebook and messenger. Otherwise you will have random lags and/or freezes.
[LG Optimus L9 P760, P765, P768, P769] cheppiroma:
It's true, that's why we have Greenify to help us all. I'll try the update now ;)

in fact, I needed Xposed for full use with Grennify and GravityBox ... but as Imer said, this update does not work for being 2nd revision. I tried the previous version 5.1.1 and does not work u.u
[LG Optimus L9 P760, P765, P768, P769] cheppiroma:

Here's another silly question. I had flashed this ROM long ago and I just remembered I had not deleted Android Secure before flashing on TWRP. But I did wipe every other memory. Is that the reason why my phone is a bit slow now? Can I delete just the android secure while updating the ROM now? Will this delete all my apps and saved data from the phone?

Hi

i have upgraded to last version 2 days ago but im having a lot of freeze (i have to turn off and on the phone) + yesterday i have lost twrp recovery and SuperSu + tonight a found a kernel panic

this morning i have tried to reflash the last version but is the same.

im going to download the previously version
[LG Optimus L9 P760, P765, P768, P769] PreemPalver:
That's weird. I assume you've got a P760 like me. I haven't experienced none of those issues. I even dirty flashed the update just wiping cache and dalvik. Concerning freezes I partially solved them hibernating facebook and messenger.

Kernel panic should be related to cpu frequencies' voltages I think. They can change from phone to phone.

I was running the 0905 version. I had switched off the phone and then while turning on it's stuck at the LG logo. Pressing Home+vol up+power button doesn't take to TWRP. To turn it off I have to take out the battery. What to do?
[LG Optimus L9 P760, P765, P768, P769] PreemPalver:
I have bad news... Correct combination to boot to artas twrp recovery is home+vol DOWN+power. Vol Up mess up the phone.
[LG Optimus L9 P760, P765, P768, P769] trumpiks:
Ugh, this is really complicated. You`ll have to try leelus fastboot to flash a CWM recovery, and then install/ reinstall ROM. Unfortunately i cant walk you through fastbooting through computer, as it is ridicilously hard, and never works for me at the first try. I had this problem a lot of times. Try connecting it to a PC or USB charger, and then do the following sequence. Take Battery out -> plug in charger-> press and hold vol down+home-> put in battery while holding->wait. If nothing happpens do the same, while holding vol up. If that does not take you to fastboot/bootloader then leelus fastboot is the only way.

This will install Recovery Software (CWM) in your phone. When finished you can disconnect phone from pc (remove usb cable).

Press Home + Volume Down + Power Button

Hi [MENTION=5872756]ALEX.IMER[/MENTION],

Your work on Lollipop is GREAT! First usable version on my P760!

hi

Turn Off the phone

Press Volume Up + Power Button. When you see LG Logo, Release Power Button

You can See Fastboot Mode on your screen

Plug in usb cable

If your pc do not recognize your mobile, search in Connection manager and install the driver (fastboot_driver.zip)

You have to copy recovery-clockwork-touch-6.0.3.1-p760.img in Android folder then run all the command
[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
For ADB and Fastboot to work, you may need the Google SDK Usb drivers. They are available in the Forum w/o the huge SDK.

After installation, they have to be selected in device manager in the "Android phone" section.

For virtual com ports(Firmware recovery in Download Mode!) and modems you need the LG drivers. These are available in the "ADB interfaces" section, but won't recognize the phone for ADB, Fastboot and when using any LG software. Only in Download Mode and for tethering, com port and modem will auto-install. That is the situation on my phone with Artas' CM11. With rooted stock everything was still alright.

I updated just the base band with Artas' hacked LG Flash Tool. If you need to flash a complete stock rom KDZ file, first try the normal LG Flash Recovery tool in Download Mode(press volume up or down while attaching the phone), if it don't work, try Artas', but I don't know whether this modded version can handle full roms. Then it's time to dispair.

With Artas' tool you see a flash failure error, whether it succeeded or not. To find out you have to reboot. If there really was an issue, the baseband may now be zeroed out, and not even Download Mode, Fastboot and Recovery work any more. Phone dead.

Common issue with CM12.1 for P760

Also I miss the NFC feature of this great firmware/phone. Please [MENTION=5872756]ALEX.IMER[/MENTION] add this feature to a new build for P760 and other models with NFC capability. :fingers-crossed:

This doesn't seems to be fixed as so many CM12/12.1 builds have the same issue even with different music players. For Lock Screen and Launcher issues I was able to manage it as it was mostly solved by replacing the default launcher (Trebuchet) with Nova Launcher. Seems like Nova is less resource hungry.

P.S. Wold be nice to include L Speed tweaks and to rename the device to P760 as PC and Play account see the device as P765 which is not quite accurate. ;)

That facebook app is really crap. Even hibernating it with greenify doesn't work because it wakes up anyway sometimes and sucks all the memory.

Answer

Thing You need:

LG Flash Tool 2014 -> http://xdaforums.com/showthread.php?t=2797190

Original LG ROMS -> http://xdaforums.com/showthread.php?t=2107971

Follow this steps:

1. Remove the battery for 10 seconds;

2. Insert the battery back into the phone and holding volume up button plug USB cable into the phone (in other words connect phone with PC), now You should be in S/W Upgrade mode;

3. Using LG Flash Tool 2014 and original LG KDZ file reinstall ROM, using option CSE Flash (it will reformat Your phone memory to compatible format, otherwise You will ran into boot loop).
