[MENTION=5799877]csk1jw[/MENTION] do you believe that alfsamsung's correction : https://github.com/alfsamsung/LG_X3_P880_v20a/commit/1c68d8793dd102e9ccb35f71ec46f47128066b86 can be adapted to your kernel ?
[LG Optimus 4X HD] ViperUSSR:
Hello [MENTION=5799877]csk1jw[/MENTION] ! Do not plan on using Mourta 3.4 kernel on your AOSP ROM ?

[MENTION=5799877]csk1jw[/MENTION]

Yes, the Omni 4.4.4 works perfect with MHL, i used it a few days ago with the Final version.

The CM i didnt tested but i too heared people what sayed in CM 10 what works withouth rotation (but Second Screen App would fix it why have landscape mode)

And in CM 11 too i heared what it have with the same problem but how i sayed the app Second Screen should fix the rotation.

I don't get such kernel panic. Perhaps that's only for LiveDisplay support which AOSP does not have. If you can provide a test case that trigger the kernel panic from AOSP, then I will consider it.

Can you provide the github link? Last I heard 3.4 kernel is not stable for P880, but the performance number is very good. I can take a look.

Can you show me the actual link to the omni-4.4.4 ROM zip file that you used which MHL is working?

Yes, this is https://dl.omnirom.org/p880/

[MENTION=5799877]csk1jw[/MENTION] Unfortunately Github not been updated for a long time, but he actively uses Bitbucket. Last update was yesterday.

Thanks to amazing zram and our developer ofc i got 2 games in one zram with minimal lags+ an app(subway surfers, fallour shelter and kernel auditor) it can probably fit bunch more apps or maybe even 3 games(will try it)..

the settings:

minfree to medium in kernel auditor(to prevent killing apps before zram is fully used)

ksm off

fsync off

deadline 128 (for stability and responsiveness, just in case)

vm settings:

u can lower the extra free bytes to 10240 it should work also, but this setting is just in case...

i didnt fine tune it... it is only for experimentation not for daily use...

to prove the power of zram!!!

Cant wait to hear if it worked for u, and how well!
[LG Optimus 4X HD] csk1jw:
Well, if there is no GitHub to host the kernel, then I don't know I would be in GPL violation to release the ROM with the kernel. And without GitHub I also can't track his changes to understand the reason behind each commit.

Can anyone of u guys install and run facebook app (not fb lite)?

---------- Post added at 05:37 AM ---------- Previous post was at 05:13 AM ----------

about this post, u need to put 200000 in extra free kb and u can change overcomit to 50 or 100...

u need to put 200000 cause if ram goes below some point, which is lower than 200000, the kernel starts writing things to nand mem and when it does that it slows our device not by actualy missing ram but by trying to free it... puting it to 200000 makes sure zram works before that, but may increase batt consumption, as i dont have enough knowledge of the linux kernel and c i cant build a kernel that doesnt do that but this is a hack in a way... So it would be nice if a dev can eliminate those writes and put some code that does what lowmemkiller does, kill apps, when zram gets full... i made an app myself that does that, but it would be nice if it was in kernel. I complained to devs all this time about unecesary writes but nobody listened, i hope now u will...
[LG Optimus 4X HD] juantech:
Really good update, i sensed more speed, smooth and a better image quality after this, good job :good:
[LG Optimus 4X HD] Legion69:
Update from prev version give me FC errors, so I decide to do clean install.

Funny thing, when I flash ROM, reboot and flash GAAPS, got many FC errors. But flashing ROM GAPPS without reboot - works fine.
[LG Optimus 4X HD] zikomik:
Screen auto rotation still not working.

on [6.0.1]Vanir AOSP its worked
[LG Optimus 4X HD] csk1jw:
I don't have any problem with screen rotation at all. It has always been working since the last few releases. Please provide more details on which app is affected and how to reproduce the issue.
[LG Optimus 4X HD] Phil_Smith:
I too think the new update is great. I had no errors at all, no lacks, crashes, reboots, nothing! Very stable and fast.

And best of all is now it seems the battery life has gotten way better. I can use my phone normally without charging it for 2 days! That's never been possibly with any other ROM before.

Thumbs up! Really great work :)
[LG Optimus 4X HD] zikomik:
I do not know it doesnot auto rotates after last 2 update. it working on diferent rom but not on this rom.

than I'm playing video it rotates
[LG Optimus 4X HD] csk1jw:
You need to tell which apps you are expecting them to rotate but they don't.
[LG Optimus 4X HD] zikomik:
None of them, only MX Playe
[LG Optimus 4X HD] zikomik:
Than I turned off auto rotation and turned it back on it wount work
[LG Optimus 4X HD] CrazyWinner:
Maybe your calibration is broken or your sensor is not working correctly. Rotation is working fine on my phone
[LG Optimus 4X HD] Phil_Smith:
I'd also recommend you check that by re-flashing the ROM. Only wipe cache, dalvic and system, then this isn't a big deal for you won't have to re-install any apps.

So do the wipes and then flash ROM, Gapps and Superuser SU.

If the problem persists, I too would think this is a hardware related issue of your very phone.

[MENTION=5799877]csk1jw[/MENTION] ; I was wondering about notrim _zram0_option : https://github.com/alfsamsung/android_device_lge_p880/blob/lollipop-eos/fstab.x3

Some news about the Mhl?
[LG Optimus 4X HD] sourly64:
Some news about build ???
[LG Optimus 4X HD] AndreaFar:
Currently I'm using Euphoria Lollipop ad want to upgrade

Is there something that doesn't work?

In the MoltenMotherBoard previous version was impossible to use QR scanner and all camera realtime scanning app. Has this issue fixed?

Are the GPS,NFC and others sensors working?

Format every time form me is problematic since I have to do a very annoying procedure with my bank to restore access token used to manage my account. So if someone can tell me more info to know if I can use this ROM daily would be appreciated
[LG Optimus 4X HD] juantech:
i used since 1 month and for all things and its the most stable what i seen on this phone, never gave me a problem or bug, in performance its good and is smooth but if you use greenify you will see the true potential in speed.

Image quality its really good, sound quality too its perfect and in general its like an stock rom but 6.0 created by csk1jw.

The things what dont works its: qr code scanner,MHL and the movemente sensor its inclined a bit to the left side but works fine.

i think what the only thing where its not really good its in videos what the quality could be better.

What i dont know its why the other day i had to flash it because didnt boot to the menu, was in android screen and i had to reflash it, could be the root or the app purify or becuse i was seeing some system files where did this but i dont now, i had 100% of battery, i go to sleep and when i wake up ocurred this, but how i sayed could be some app.

and the battery life its really good, usually i have from 2 hours to 3 of battery(with the screen on) but if you play heavy games you can have - but its normal.
[LG Optimus 4X HD] Phil_Smith:
First of all, for me this ROM is the most stable I've tried out, too.

But I don't know what Greenify has to do with speed improvement. It is an app that can put other apps in a sleep state, in order to save battery, but is useless on 6.0.1, for this android version has an integrated doze mode which does a perfectly fine job in putting app background activity to sleep, when not using the phone for a while.

I can confirm that QR-scanning does not work.

I didn't try out MHL, but I'm a little confused... Aren't you the one who figured out, that MHL allegedly does not work?:

"Issue - MHL/HDMI does not work (by [MENTION=6748691]juantech[/MENTION])" (overview post on the top of the first page).

GPS does work for me.

I too once had to reflash due to the very same problem of being stuck on the boot screen, but that only happened once on a previous build.

This is also true for me, especially when the phone is lying around for a while and the doze mode is induced.

When not heavily using the phone, this way battery can last for days.

Regards
[LG Optimus 4X HD] juantech:
Well i know what dooze saves battery, but the ram of some persistent apps remains here, the only solution here its hibernate it, for this i use greenify, with + ram you will have more speed you have to test it, its really cool :) all flyes and its really smooth.

And about the Mhl yes, i sayed what dont works, but you understanded bad, i sayed what not works other time, i didnt sayed what works ;)

And about you sayed of the not boot... i think this is the most bad of this rom, then other day we will have the same bug and we will have to reflash it and loose all apps :(
[LG Optimus 4X HD] Phil_Smith:
Well, I don't know... When awaking your phone from hibernation you wake up the hibernated apps, which can cause lags (also discussed in the Greenify xda threat). Also, as soon as you're out of hibernation the RAM is being filled with requested apps (also the very ones that you had put to sleep with hibernation). For what I understand the benefit from Greenify is saving battery life (a marginal amount at best using android 6.0.1). All side effects of that can be and sometimes definitely are a problem reducing the response time of your phone for a while, but correct me if you can explain why I'm wrong.

Ah okay. Maybe this has to be explained a little more detailed in the bug list, then. But let's await the next build :) Maybe [MENTION=5799877]csk1jw[/MENTION] has solved this by then :)

Yeah, that was surprising... Didn't get it to work either by only formatting cache, dalvic and system. Had to wipe everything in order to get it to boot again (can't explain why).

But as I said - this happened in a previous build for me, and never on the latest one. How about you?

Greetings :)
[LG Optimus 4X HD] juantech:
Yes, in the not boot problem i did the same: wipe system,dalvik,cache and didnt work, and too tried to return to an older version for see if boot but was useless...the only choice here its wipe data :( and i was using this last update.

And about the greenify and the hibernation, i use greenify only for hibernate the app what i select every time, i see what app its using ram and these apps i hibernate, i had 2 or 3 on first thread, i hibernated it and now the phone have more speed and smooth, but i have to do every time when i open some of this persistent apps like sygic, outlook or cm browser.

Its the ram what if you have more you have more speed i sensed allways in this phone.

i not use autohibernate because dont works for me on greenify, before i used it on purify app and gave me the same results but purify not is available now on playstore.

And the response its better, greenify only uses in my case 5mb of ram, with xposed yes i heared what gives you lag but i didnt installed this.

And yes have this rom with working Mhl would be the thing what i allways wanted on this phone, all with great quality,good battery and really fast and smooth, and so stable like an stock rom with this feature :D
[LG Optimus 4X HD] Phil_Smith:
Thanks, good to know that this can happen using the latest build :/

If it is more free RAM that you want, you can try out Kernel Adiutor. With the app you can a) assign more Z-RAM and b) use a bit of a more aggressive setting for low memory killing.

So long! :)
[LG Optimus 4X HD] juantech:
thanks for the tip man ;) but i dont know how works z ram, i see what in every app i have an 1% of zram but i dont know more of it.
[LG Optimus 4X HD] Phil_Smith:
Z-RAM is comparable to virtual memory in Windows (see https://en.wikipedia.org/wiki/Paging). The system uses hard drive space to compensate for a small amount of physical RAM when needed.

As our phone isn't the newest and many of the later apps we run using 6.0.1 require more RAM than we have, I recommend you pump that up to the max.

Only downside is, that hard drives are much slower than RAM. But speed alone is of no use, when your system permanently runs out of memory.
[LG Optimus 4X HD] juantech:
but i heared what if you use memory for ram the life cicle of the memory will be reduced while you are using it because of constantly rewrites, but thanks for the info now i know how works :), what i dont know its why all apps uses zram when my ram its not full. (an 1% of the ram in every app its zram)
[LG Optimus 4X HD] Phil_Smith:
I can't tell you the background in detail for android. In Windows this is also true, but adjustable. When a system has 8GB of RAM+ I always turn off paging, which for me seems to fasten the general response time.

If you don't turn paging off explicitly, the system will always automatically assign a bit of virtual RAM, who knows why (I know some programs really needed virtual RAM, but that seems like a log time ago).

For our p880 - Unfortunately we cannot turn off paging so easily, without having way to little of total memory...

And if it is turned on anyway, then it should at least be enough if needed, in my opinion.
[LG Optimus 4X HD] InterrtuptoR:
where did u see that 1% of every app is in zram, did u use some app?
[LG Optimus 4X HD] juantech:
go to settings,memory, used memory, and select one app, here its all details about ram and zram usage.

pls share the link to new rom thread here when u decide on sharing :D

couple of days ago i stumbled on sony official tutorial about making the nougat for their phones and thought of sharing it here and asking you to try and build it for our phone :D And today i opened xda thinking maybe somebody build nougat, lets check it :D

I know c, c++ and java if u need some help, i dont know much about building but can build if i have sources...

Can add governors xD but the rest...

I want to learn...

U rock man!!!
[LG Optimus 4X HD] csk1jw:
Please share it here anyway. Any form of Nougat porting resource will be very helpful as I still learning. The Marshmallow work was realized much due to the porting from AOSP 6 grouper.

You're great. I am a complete noob on java, which is the main language in Android framework. I am mostly guessing my way through my understanding of C/C++.

Did u change smth to get the nougat to boot, if u did how did u know what to change, where did u find the info on that?

AOSP Nougat

Update:

- Most functionalities are now on-par with MM ROM.

- WiFi, BT, NFC working

- GPS and network location service

- RIL is alive, but not yet into field trial

- Audio

- Stagefright OMX hardware decoding

- Youtube video playback

- Front/Back Camera - Picture Mode

There is *ONE* big hurdle - Camera video recording. It seems that Google stripped off pieces of legacy Camera HAL support in Nougat. Starting video recording would stall the Camera and leaving frame handling thread hanging in the background until the phone is reset.

Researching on other pre-2013 non-Qualcomm device which have Nougat porting WIP, I found Galaxy Nexus (Ti OMAP4) having similar issues with video recording from posted logcat dump.

This is going to be challenging to make video recording work for Nougat for non-Qualcomm device.

If anyone knows any other non-Qualcomm device which have Nougat porting WIP, please share it here for learning and exploring ways to solve this.

Google finally cleaned up the mess in GPS framework for Marshmallow and Nougat and enabled us to implement better fix that what we had in Lollipop. I think I overlooked this for Marshmallow.

Have u rebooted several times after installing? Sometimes the deep sleep will kick in after rebooting.
[LG Optimus 4X HD] juantech:
I use Rom Manager (CWM) for enter to recovery via app, download it, its the best app for this, detects the recovery what you have and all.

i rebooted 1 or 2 times but do not convinces me, puffin browser its more laggy and all its less smooth, there is no deep sleep, its a thing named SO Android what not saves battery with the screen off.
[LG Optimus 4X HD] b886b:
Will try ROM Manager for rebooting to recovery, with a broken volume key it is really difficult to enter recovery mode.

[LG Optimus 4X HD] csk1jw:
No, LG-P880 kernel always have time-out mechanism for dealing with baseband wakelocks. Baseband_xmm_power will periodically wake up the device as this is required to service cellular events, unless you put the phone in airplane mode. This is considered normal. The battery life won't be the same if the phone has an active cellular network vs using the phone as WiFi tablet or in Airplane mode.

[LG Optimus 4X HD] Phil_Smith:
Hi Kessaras,

do you think this will work with [MENTION=5799877]csk1jw[/MENTION] 's Nougat 7.0 ROM (located here)?

- Can I break something, if it doesn't?
[LG Optimus 4X HD] kessaras:
Hi Phil, I don't know. Probably yes because nougat has only few differences from MM , so the app should work and the dev of nougat is the same so he uses his own same sources for this ROM. But honestly I won't test it because multitasking in p880 and MM is already heavy, I can't even imagine p880 splitting windows on the screen (and also I hate viewing 2 apps at the same time since I will only focus to one at a time)
[LG Optimus 4X HD] Phil_Smith:
Thanks, but I was referring to the script that allows me to set my zram to a higher amount.

What does this have to do with splitting windows? Am I missing something?
[LG Optimus 4X HD] kessaras:
I mean the whole nougat. Since the only new feature is splitting windows and on the go doze. So it should work. Test it without fear. The worst case scenario by using it is to do nothing at all since if you delete it after reboot you get the default values again.
[LG Optimus 4X HD] Phil_Smith:
Ah thanks - you won't try the new ROM, but I can try your script without having to worry - now I got you :)
[LG Optimus 4X HD] juantech:
Im using this rom since much weeks, and never gave me a problem or bug, but im using the previous version not this, i think its more stable than much other LG Sony or Samsung Official roms, csk1jw did a great job with this.

(the motion sensor its inclined to the left side this is the bad, this and the MHL and qr code scanner but nothing more, all other things works perfect)
[LG Optimus 4X HD] Phil_Smith:
Can you provide me a link to the 3rd party app you're using?

Tried "kernel adiutor mod", but it only lets me set zram to 1GB (as before).
[LG Optimus 4X HD] OFFICIALTCH:
Can I use this On my GT-S5690?
[LG Optimus 4X HD] kessaras:
Init.d script support

I hope it works on nougat. Its a very old app that help us use our init.d scripts on boot. If it doesn't work on nougat then try other apps randomly that have init.d editor , open the script in a file explorer and copy paste the content there.

---------- Post added at 08:42 PM ---------- Previous post was at 08:40 PM ----------

Every kernel is different. I don't know if it will work , but again the worst case scenario is to fail and do nothing, so you delete it and reboot the phone to restore all settings.
[LG Optimus 4X HD] Phil_Smith:
Sorry, I meant the app with which you actually set the zram (your screenshot says Ram Expander, but there are many apps of the same name)
