SU 2.78 version works well in my LG P880.....SU 2.46 didn't work because its not supporting Android 7.0...

I am using stock gapps...

I have flashed through CMW recovery...

Great work.

Fluid, few lags, needs to improve battery life, but that's a problem even with official 7.0 Nougat in Nexus.

We all need to be patient and wait for a revelation... so.... grab a nice beverage and keep up with the good work [MENTION=5799877]csk1jw[/MENTION]

Unified kernel

For quite some time since I started working on porting the CM-12.1 kernel for Marshmallow and Nougat, I had been plagued with kernel issues that any feature I tried to implement, the kernel would stuck in reboot loop. So I ended up implement only the bare minimum kernel just enough to boot. I finally had some time to look into this problem and found that the kernel panic because it couldn't load the init ramdisk. And I concluded that I was hitting the size limit for zImage from LG bootloader. So I ported XZ compression for kernel and the final zImage was reduced by ~400KB. Now, all the previously ported features were working once again.

- uid_cputime

- KSM deferred timer

- Moto F2FS kernel update from Marshmallow-6.0.1-release-griffin

Finally, the kernel is more complete in term of Android support and F2FS is back to business. The kernel is also unified and works for both Marshmallow and Nougat.

Regarding F2FS support in kernel, I once ported the Moto G version for Lollipop, but extent cache mount option was not supported. This time the Moto F2FS kernel update was ported in full.

I will be releasing the patch to CM-12.1 kernel source shortly.

Is it possible the rom port to HTC one x
[LG Optimus 4X HD] Salman Al-Badgail:
Did anyone tried new BUILD??
[LG Optimus 4X HD] Salman Al-Badgail:
Alright I have tried Latest Build. ROM is good and fast. Needs 3-4 reboots for getting fast.

1-No reboot option (This can be done from HERE) req ROOT

2- Battery Drain Heavy ( This can remove by Battery apk Attached below)

3- Root Booster (attached)

4- No gallery... ( I dont like G-Photos)

I attached SuperSU. Thanks to [MENTION=7008914]Phil_Smith[/MENTION].

Can anyone provide me flash-able gallery for this ROM and also a good file manager for copying files to ext-sd.

I had also disabled Gapps (i.e present in stock gapps)

No Battery % on status bar.

NO am/pm

No sound Mode (Gen/Sil)

Appreciate your hard work [MENTION=5799877]csk1jw[/MENTION] :good::laugh:

EDIT: Removed Root Booster Pro (Since it was other work & also against xda community Rules)
[LG Optimus 4X HD] b886b:
Thanks for your review [MENTION=7114291]Salman Al-Badgail[/MENTION], though I am not on this rom but I have heard that you can have battery percentage displayed in the status bar by enabling System UI Tuner. U can give it a shot.
[LG Optimus 4X HD] Phil_Smith:
How did you install gapps? I get an endless loop in setup wizard, both with modular and opengapps stock...

---------- Post added at 05:17 PM ---------- Previous post was at 04:25 PM ----------

Didn't work in the last build, although the app shows that option.
[LG Optimus 4X HD] csk1jw:
I think your GApps installation was replacing the stock AOSP Gallery. It is there for every ROM I released out there. I have always been using Gallery myself instead of Google Photo.

If you're using OpenGApps stock, then you should configure the installation using .gapps-config to choose what not to install. See 1st post on example of config file that I attached. Check OpenGApps wiki for more information.

The new build has UID_cputime implemented in kernel and I had also enabled Android framework KernelUIDCputime to support per UID battery bashing. The battery stats reporting will be more accurate. I don't think there is any issue with battery drain from my daily use compared to the last release.
[LG Optimus 4X HD] Salman Al-Badgail:
[MENTION=7008914]Phil_Smith[/MENTION] I am using Open Gapps you can found it HERE (ARM-7.0-Stock)

[MENTION=5799877]csk1jw[/MENTION] Photos (replaces stock/AOSP Gallery) Thanks for your help. :good:
[LG Optimus 4X HD] FaySmash:
you have to install rom and gapps without reboot between and only works with CWMR not TWRP
[LG Optimus 4X HD] Salman Al-Badgail:
In my view ROM is stable and good. [MENTION=5799877]csk1jw[/MENTION] have done good work. NO random crash, I am using it for last 2 days and I will continue to use until we get 7.1 LOL :D or similar ROM or andriod 8,9,xyz heheheheh.....

Better than STOCK ICS for me
[LG Optimus 4X HD] sourly64:
Thats not really right I use TWRP 3.0.2.0 and it works,but Rom is sometimes fast and smooth another time it is very slowly and needed

much time to go in Playstore or to the account.Also by gaming like RealRacing sound is broken and it lags much

Thanks for work ,thing it get in future better :good:

Regards
[LG Optimus 4X HD] Phil_Smith:
As I said, I tried Gapps Modular and I also tried Opengapps Stock. With both I have the issue that right before the setup wizard is supposed to finish, it crashes saying "Unfortunately Setup Wizard has stopped", but then only offers me the option to start over again from the beginning.

Also I do use CWM recovery (and I do not reboot in between ROM and Gapps installation).

Any ideas?

---------- Post added at 01:06 PM ---------- Previous post was at 12:51 PM ----------

Here is a rather simple file manager I like using. Wait a bit after installation, if you can't access your storage immediately.

You can also enable a free addon under the Add-Ons menu called Root Access, with which you can access all system files and so.

FX File Manager
[LG Optimus 4X HD] Salman Al-Badgail:
Try re downloading it. I suggest you open gapps. let me know your CWM ver??
[LG Optimus 4X HD] Phil_Smith:
Okay, I'll try that and see, if it is an error with the ROM download
[LG Optimus 4X HD] Salman Al-Badgail:
Great, I will be waiting.

I got error command log with latest build while installing but no problem in boot, everything was working fine. I use CWM touch 6.0.4.5
[LG Optimus 4X HD] Phil_Smith:
Oh yeah... I'm using the CWM 6.0.4.5 non-touch version. I will try the touch version you uploaded.
[LG Optimus 4X HD] Salman Al-Badgail:
Try latest build, its fast and stable, I don't know about Game but play store is working fine and fast, It took me 3-4 reboots for getting stable.

[MENTION=7008914]Phil_Smith[/MENTION] did you follow the clean installation procedure ????
[LG Optimus 4X HD] Phil_Smith:
Yes I did. Wiped/formatted everything. Last thing I might try is keeping the files on the internal drive. Other than that, I don't see what else I might be doing wrong...
[LG Optimus 4X HD] jrcquinito:
hello a question: there is already version of Xposed modules for this Rom ?. It is that I have become so accustomed to Rom 6 with Gravity Box module not to use it in a big drawback.

If you can use me I upgrade to this version.

A great job keeping alive the 4xHD Lg. Keep going.

regards

Hola una pregunta: hay ya version de modulos de xposed para esta Rom?. Es que me he acostumbrado tanto a la Rom 6 con el modulo de Gravity Box que no poder usarlo en un gran inconveniente.

Si se puede usar me me actualizo a esta version.

Un gran trabajo mantener vivo el Lg 4xHD. Seguid asi.

[LG Optimus 4X HD] Phil_Smith:
Got it to work. I think maybe installing from internal storage might have been the solution.

Welcome [MENTION=7008914]Phil_Smith[/MENTION] good to see that you are up on new build. Disable stock apks if you are not using it.

I put files in ext-sd and work fine for me. Anyway either storage works :) :D [MENTION=7008914]Phil_Smith[/MENTION]
[LG Optimus 4X HD] FaySmash:
yes, this could be the solution indeed. glad it worked out for you.
[LG Optimus 4X HD] csk1jw:
If you setup the device fresh as of coming from other ROMs, then you should wait for the background sync to complete. No reboot is necessary. If your GApps is outdated or missing the correct DPI version, then the fresh install would also be sync'ing with Playstore for update. When those activities are taking place, the device will lag. It can't be help as it is pre-2013 hardware specs, the EMMC storage is slow. Nougat SetupWizard allows setting up new device without any network and Google account. This way is the fastest way to setup the device and get to the Home screen. Once you add the Google account, the device will lag until all sync activities completed for the 1st time.

On rare occasion (if you play with the same Google account on multiple device and different Android version), sync may fail. And, the sync may be retried periodically until it can resolve the conflicts somehow. If this happens, you device will lag from time to time and in the worse scenario, you get battery drain and the device gets warm to the touch.

I don't know what could be wrong at your end. It really does not matter if you were installing from internal storage or microSD. Perhaps, your filesystem was corrupted somehow. You can use FSCK winthin CWM recovery to check and fix filesystem issues.

If you are using OpenGApps stock, then you should check my attached gapps-config.txt in 1st post to skip unnecessary GApps to reduce the stress of background activities and memory utilization.
[LG Optimus 4X HD] zikomik:
When ambient display is on, button light remains involved
[LG Optimus 4X HD] Salman Al-Badgail:
Yes you are correct,This might be the reason for lags.

Yesterday night I tried to remove stock G-apps (Use-less) via Titanium Backup Pro and later I install a apk through play-store for for screen recording, I succeed in removing stock apks and installing screen recorder, I record a 1min video, when I tried to stop video it got stuck and when I pulled battery out and in, It shows LG logo but no boot .img (Android) after Lg logo it was black. Can anyone tell me why this happen. But for now I flash again and now its everything fine and working Good.

It would be great if anyone can make G-apps.zip according to Csk1jw req list for flashing this ROM there are many useless apks present in stock
[LG Optimus 4X HD] Phil_Smith:
You simply have to create a file called "gapps-config.txt" and copy-paste [MENTION=5799877]csk1jw[/MENTION] 's list into it (file of the same name attached in first post).

You don't have to manipulate the gapps.zip file. Just put gapps-config.txt and your gapps.zip into the same folder. The elements in your list will be skipped on installation then.
[LG Optimus 4X HD] Salman Al-Badgail:
Appreciate :good:
[LG Optimus 4X HD] b886b:
In the change log it says the kernel now supports F2FS, has anyone tried using that? And is there any real gains in doing so? [MENTION=7114291]Salman Al-Badgail[/MENTION] I knew that u have tried both 6.0 and 7.0 roms, would you recommend jumping from 6.0 to 7.0 and why???
[LG Optimus 4X HD] masmoe:

[LG Optimus 4X HD] Salman Al-Badgail:
In my view this ROM is good and fast, slightly fast to MM. ;)

About gaining or not is different thing, Different users have different views on a particular ROM. I think you should give a try for New Build and share your opinions/views with community. About F2FS I haven't tried (no knowledge) :confused:

Coming soon: Android 7.1 Developer Preview Information Only
[LG Optimus 4X HD] Phil_Smith:
Now running the new build for a couple of days, I want to share my impressions.

good

Way quicker boot time than in any other ROM I ran.

The general speed is very impressive. Turn off transition animations in developer settings, if you don't care about stuff like that and mainly want your phone to respond quickly.

Natively built in close all button in app view

Android ****ing 7 on our p880! :)

negative / strange

I still experience some random app crashes from time to time - not that many, but also one cannot ignore their commonness.*

Sometimes - again not often but still - I get a spontaneous battery drain. For example this night from 100 to 0. Anyone else having that problem?*

Quite often I get random restarts.*

Again I'm having that audio problem... The music hangs and mechanically stutters completely for a few seconds when entering or leaving the lock screen.*

Xposed still not available for 7.0. Isn't a big deal for me, but I think for others it might be.

* Concerning all those crashes and stuff, I somehow get the feeling that this might be an issue of my very phone. So can others please share their experiences about that stuff, so one can get an objective impression about the overall stability of this ROM version?

information

When installing gapps stock, you can exclude unnecessary gapps by creating a text file "gapps-config.txt" and put in [MENTION=5799877]csk1jw[/MENTION]'s list attached in first post. Now put gapps.zip and the .txt file into the same folder on installation in order to skip the elements in the .txt file.

When wanting to use adaway, you can apply this fix to circumvent the "can't write host file error": post 88

The advanced restart menu can be brought to life using "Reboot (Material design)" - Thanks for that, [MENTION=7114291]Salman Al-Badgail[/MENTION] ! (Reboot to recovery still does not work though...)

For getting rooted, you need to flash the latest SU zip via recovery older version than this won't work

Thanks for keeping it up so amazingly well, [MENTION=5799877]csk1jw[/MENTION]!
[LG Optimus 4X HD] Salman Al-Badgail:
I got 2-3 times only Whats-App crashed

No restarts, No heavy battery drain ( I already attached Battery Saver Pro previously) . For music I am using MUSIC PLAYER.

That's strange that you have too many problems and Thanks for INFO.

Anyone up with same problem.???? [MENTION=7008914]Phil_Smith[/MENTION] choose slumber profile in Battery saver.

I did not tested reboot to recovery.
[LG Optimus 4X HD] Phil_Smith:
Thanks, hm, strange that you don't have that many problems (or strange that I do).

I'm having the same problem with every music player, also with the one you suggested. I see if I can fix this somehow, but I had this before, and back then it magically disappeared as strangely as it appeared before...

About battery saver: Doesn't Android 7 have a native doze mode, or do we need a third party app for that?
[LG Optimus 4X HD] Phil_Smith:
Thanks for the information. I attached the result of that. I don't know what those results mean. Can anyone help interpreting them?
[LG Optimus 4X HD] Salman Al-Badgail:
No battery app is req for this ROM.

[LG Optimus 4X HD] csk1jw:
You just run it on the cache partition. You need to run it on the data partition and the microSD partition to fix any potential filesystem corruption.
[LG Optimus 4X HD] Phil_Smith:
Thanks, now I think I got it. At least I was able to run it on data, system and cache using e2fsck.

But how about the external SD? e2fsck can only check ext2, ext3 or ext4 partitions (if I understood that right). The external SD though is formatted in fat32 (shown as vfat in the "cat /extc/fstab" list).

What's the command for checking that? Didn't find the answer googling up to now...

---------- Post added at 10:04 AM ---------- Previous post was at 09:31 AM ----------

Okay, I think I did the right thing now using fsck_msdos for the fat32 external SD card.

For everyone who's interested:

go into recovery

cmd admin

adb shell

cat /etc/fstab

# see a list of mount points (data, cache, ...)​

e2fsck -pcfv /dev/...

# type everything until first whitespace. Do this for system, cache and data​

fsck_msdos -y /dev/...

# do this for your external SD​
[LG Optimus 4X HD] Phil_Smith:
I would love to try that out, but I don't know how to do it.

A guide said this could be achieved with twrp, for the latest twrp has the option to change the filesystem, which of course is true, but changing to twrp, I only found the option ext2,3,4, FAT and exFAT...

Does anyone know how to theoretically change to F2FS?

Edit: After a little more research, I think the question can also be formulated as: Is there any recovery or mod for our device that supports f2fs?
[LG Optimus 4X HD] b886b:
The only F2FS thread I can find is this one, http://xdaforums.com/showthread.php?t=2799610.

However, it is a bit old. Maybe the OP can enlighten us.

Can anyone provide me latest file Manager-flashable.zip without any permission by OS. I had installed many file-manager apk from play store and ended in permission.

Needed for this ROM.

[LG Optimus 4X HD] Phil_Smith:
I posted a request in that thread. Let's see if someone has a compiled recovery version lying around.
[LG Optimus 4X HD] masmoe:
As I remember, that tecovery not stable yet. Need several times try to format the partition and sometimes the f2fs partition back to ext again that cause data corrupt.

I am not following the f2fs development but at that time the f2fs are not so stable.

Last time I tried f2fs on KitKat.

Can a sdcard improve performance of our device? Using it as internal storage for rom and etc? Is there an sdcard that is faster for our device than our internal storage?
[LG Optimus 4X HD] Phil_Smith:
I don't know whether installing the ROM on an external SD is gonna work or show benefits for that matter, but you could buy software like RAM Expander in order to set your swap file on an external drive, which will most probably increase performance.
