Hi there,

please excuse my questions about the file system.

I had forgotten that FUSE was replaced by SDCardFS.:mad:

Kernel : GPL & thermal 'skin_pred'

[MENTION=5799877]csk1jw[/MENTION] , in case you need it, I have uploaded your latest 2016 Dec. patches (GPL) here : https://bitbucket.org/oF2pks/cmp880devkernel/commits/branch/aosp6-7

As you can see, for cm12 los13 and twrp3.1.1, I use this: https://bitbucket.org/oF2pks/cmp880devkernel/commits/all ; when you bring out your 2017 patches, I will upload them...

Can you explain what is thermal 'skin_pred' for and how/why it is implemented in aosp6 & 7 kernel ? Thankfully Aida64 still shows real thermal nct1008 and, on un-modified aosp7, boot/install phone can become quit hot (80°C), while thermal 'skin_pred' fakes most apps. with lower values (40°C).

Also, I remember that you can now multiboot other roms, without a kexec-ed (like Cyospak7-2016) kernel on primary (regular recovery install). The most interesting is original lg JB (v20c&d) which is the only rom to provide :

-FMradio

-(non buggy) GPS without wifi & cell/sim network

-certified Playstore

Cross booting will be much faster if you patch your aosp7 with kexec : https://bitbucket.org/oF2pks/cmp880devkernel/commits/d4dfb8225f3fa4dd2efc75db0f0b12aea183a432

how can we solve the problem of heating
[LG Optimus 4X HD] ze7zez:
I checked on the same P880 that after calming down the system, all custom ROMs (4.4 - 7.1.2) on the CPU-Z show the nct1008 temperature about 10 °C higher than the stock ROM.

In my opinion, this is not a feature of only AOSP, but probably a feature of lack of CPU optimization from NVidia, not available for developers.

I will do the same CPU load test on stock ROM and aosp7 and as I finish it I will add in this post graphs.

Anyone can use a script to test the cpu temperature.

For stock:

while
do
cat /sys/class/thermal/thermal_zone0/temp >> stock_cpu_temp.txt
sleep 1
done

For aosp7:

while
do
cat /sys/class/thermal/thermal_zone0/subsystem/thermal_zone0/temp >> aosp7_cpu_temp.txt
sleep 1
done

[MENTION=5799877]csk1jw[/MENTION] , first off thanks for the great rom, have been using the latest build for more than a month now and is very pleased with the performance and stability. Just wanna know if an update for October security fix is available or not?

---------- Post added at 02:49 PM ---------- Previous post was at 02:46 PM ----------

You can use an app called systemui tuner for battery percentage . The charging behavior you mentioned is intentionally implemented by the OP for those have problem turning on the device with a broken power button which I personally is experiencing and found that really useful.

Google didn't release September & October 2017 security patch for 7.1.2 code branch. All other code branches, 8.0.0, 7.1.1, 7.0.0 and even 6.0.1, have them. I have 7.1.1 build with 2017-10-05 security patch level tested. I just wait and see if Google will do it for every code branches for the November security patch, which should be ready for a couple more days perhaps, which should include the fix for KRACK WPA issues.

I don't have the time and motivation to backport from other code branches myself into 7.1.2. Let's just hope Google will do it and I will just leverage from their work. :)

Otherwise, I will temporary go back to 7.1.1 build.
[LG Optimus 4X HD] ze7zez:
58 builds Nougat 7.1.1 for 11 months (2016-Dec-01 - 2017-Oct-02) versus 33 builds Nougat 7.1.2 for 3 months (2017-Apr-02 - 2017-Jul-28):

The build time for Android 7.1.1 is 8 months longer than for Android 7.1.2.

I know this after testing on my Nexus 4 that Android 7.1.2 is more demanding for hardware than Android 7.1.1.

If you are still wondering whether to make AOSP based on Android 7.1.1, then I hope my arguments will convince you eventually.

Newer is not always better.

LG P880 Optimus 4X HD

Just installed:

p880-ota-eng.nzh54dz.zip Sep 20, 2017 | 07:24AM

And Gapps 7.1 stock. Bootloader CWM 6.0.4.5

Installation ok! And the device is working increadible fast!

But a big problem it has is, I think the Google services are not working properly. Log into a Google account brings up an error message, therefore Play Store and stuff are not opening!

Tried all other gaps but STOCK is the only one seem to work but it slows the device very much!!!

I thought to install all Google Services manually by apk files but cannot launch them because Gapp Pico do not have a file manager or browser.

Any ideas to get Pico working, because as I said, it is running very fast.
[LG Optimus 4X HD] sourly64:
You need webview zip :cool:
[LG Optimus 4X HD] khan.cross:
I have tested it all night and found a better solution. It is definately not webview but it's kind of web services which the Gapps Pico does not bring with.

And QR Code scanning does not work!

Here is my tutorial to a jet fast P880:

1. Download Opengapps pico and aroma.

2. Download Nougat 7.1.2

3. I used bootloader CWM 6.0.4.5

1. Boot into the bootloader

2. Wipe everything what you can

3. Then install from zip and first install nougat, afterwards pico, at least aroma.

4. In aroma you have the possibility to choose which gaps you want to install and which not. Only select CHROME!!!

5. Do the installation and finish all. Reboot and voila! Google Play Store is working :good:

Here are some screenshots, the aroma installation should look like this at summary screen.

Aroma zip

Hi bro,

I try to install like your tutorial

i downloaded opengapps pico and aroma ,

but by installing this both it get aborted,

so maybe the files are wrong, will try again to download

but the aroma zip is very big and iam now on the philippines with sometimes slow internet connection

Iam back with my webview zip and older pico gapps

Phone works sometimes really fast and othertimes its laggy by using for example Facebook, Maps and other apps who needed to sync. I think thats is the problem

Google is Mandating Linux Kernel Versions in Android Oreo

By the way, I wonder what [MENTION=5799877]csk1jw[/MENTION] thinks about it?

P.S.

Meanwhile, android-7.1.2_r36 (N2G48H) was released.

I would be very happy if OP gave us a surprise before Christmas or New Year.

[LG Optimus 4X HD] InterrtuptoR:
I have official Google made oreo 8.1 for nexus 5x and my kernel is 3.10 not 3.18... i forgot what are your kernel versions but i remember mourta bragging about porting a newer kernel to our device but i doubt it was >=3.10
[LG Optimus 4X HD] ze7zez:
We differ from the topic of this thread and OP can erase us.

I do not discuss any more. Only a small explanation.

This is not the point that it is impossible to adapt solutions prepared for kernel 3.18 in older kernels, but how much work you have to put in order to work similarly.
[MENTION=2233641]AdrianDC[/MENTION] has a huge achievement in this respect, because he is currently creating android 8.1 on the 3.4.113 kernel!

Stumbled upon this thread yesterday and wiped my eyes. Nougat for p880, I could'nt believe it. Since my old p880 is pretty worn out, I used it as a webradio alarm clock besides my bed for years without any upgrades.

Installed nougat googlefree without any gapps and whow.... its real fast.

Fastes webradio ever had at my bed :cool:
[LG Optimus 4X HD] niceplay:
Awesome performance and stability with microG

I've installed unofficial microG via fakegapps included in Xposed-Framework and this rom runs very stable and fluent with 330-500Mb free ram.

During installation of unofficial microG i've chosen Google Playstore and all my apps included Playstore seems to work fine.

With gapps, i wasn't able to install any rom newer than Kitkat without massive lagging and freezing.

In Xposed i use GravityBox to customize this rom.

The only problem is that the alarm clock doesn't work correctly in deepsleep(described it at page-84, post-#835).

This is a real problem because I can only fix this by using Cyospak7 kernel. We tested this with Gapps and the alarm often starts,

but sometimes minutes too late (often only when I wake up the phone via power button).

Maybe the alarm was only triggered by Gapps-wakelocks, because without gapps(but with new alarm-clock) the alarm timed out.

In my opinion it's the best and one of the most stable roms for the good old but renewed P880.

Many thanks to csk1jw and keep on coding!

I have a question, is our device compatible with Substratum ???
[LG Optimus 4X HD] EPa:
So I would like to go back to stock just for video recording (want to use the device as in car camera) but for some reason my cwm backup says md5 checksum is not correct and there goes my backup (?).

Would anyone know of a way to go back using kdz files which I have (or otherwise, as in some official rom I could flash with cwm)? Maybe convert kdz file to something I can flash with cwm?

Tried the LG tool but it reports I have the latest firmware. Also option upgrade recovery doesn't work, it fails with the low battery message (when it's over 90%full).

Pointers please?

Optimus 4X HD Q&A, Help & Troubleshooting - a very good department in which YOU SHOULD ask questions and seek hints.

DailyRoads Voyager - a very good recorder for the vehicle (also for AOSP Nougat 7.1.2).

Enox rom - very good modified stock ROM.
[LG Optimus 4X HD] EPa:
Thanks but,

Help & Troubleshooting:

a very good place to ask about this rom and not get answers or be referred back here. This rom isn't even mentioned on sticky threads about available roms kernels guides etc., and my experience on asking about dead devices in Q&A threads isn't encouraging.

DailyRoads Voyager:

Been using it for years, thank you (I didn't ask what kind of app to use). The problem with this nougat rom is video (in general), is unusable without LG's driver, that's why I want to go back to my JB and daily voyager setup.

Enox rom:

by mentioning kdz files I thought it was clear I am only interested in official stock roms.

So, any help on the matter at hand? Namely a way to downgrade from this rom to official ICS or JB since the standard methods (described in other threads) don't work?

Idk how cwmr over twrp should made a difference...my bro has the same problem on his jiayu s3s with twrp. think I'll have to wait for opengapps team to fix it. I'll never use cwmr again...
[LG Optimus 4X HD] CrazyWinner:
Can you try this ? If you are using twrp you need to reboot recovery after you install rom. (install rom>reboot recovery>install gapps>install webview)

https://www.androidfilehost.com/?fid=24459283995309915
[LG Optimus 4X HD] Phil_Smith:
I can't tell you why the difference exists, but I'm pretty sure it does.

I followed this and the aosp 6.0.1 threat from the beginning, and almost every problem with gapps could either be solved by installing webview or using CWM instead of TWRP.

I experienced that myself. using TWRP the gapps installation always failed and I tried everything, until I somehow fixed it (creating a rather ridiculously complicated installation method), but then there were other issues, like I wasn't able to sync contacts with gmail...

After that I switched to CWM , and there were no problems at all.

I think you will have to consider trying CWM, but waiting until it is somehow fixed is a way, too. For me, I'd rather like to have a great ROM than a slightly more handy recovery.
[LG Optimus 4X HD] FaySmash:
thanks, I'll try.

I use my P880 only as alarm clock and testing device. using aptoide for now until there is a fix ^^
[LG Optimus 4X HD] b886b:
This is indeed very true, TWRP seems to have some kind of problem with the combination of AOSP Rom and GAPPS. So for now staying with CWM is the only solution.
[LG Optimus 4X HD] Worlther:
For me device is freezing with any data transfer (mobile or wifi) on every rom, so this is one from the best.
[LG Optimus 4X HD] CrazyWinner:
Use adaway. Ads are freezing our device. I'm using 6.0.1 with adaway and it's not freezing at all
[LG Optimus 4X HD] Phil_Smith:
+1 for using adaway.

When trying to do that on android 7.0, you will encouter a problem with writinig the new host file.

To solve that make sure you got adb working and your device is rooted, connect your phone ("charge only").

Open cmd as admin and navigate to your adb installation folder - For example, I type (and always hit "enter" after each line): cd C:\Android\sdk\platform-tools

Then type:

adb root

adb shell

su

mount -orw,remount /system

rm /system/etc/hosts

ln -s /data/data/hosts /system/etc/hosts

mount -oro,remount /system

Then, do not reboot and try to apply the host files again.
[LG Optimus 4X HD] FaySmash:
tried it...didn't work. -> twrp -> wipe -> install rom -> reboot -> install stock opengapps -> reboot -> install webview and supersu -> wipe cache -> reboot...gapps still crashing.
[LG Optimus 4X HD] Phil_Smith:
I remember I got 6.0.1 to work using twrp (as I said before there were some issues, but it didn't crash) by ...

making all wipes (cache, dalvik, system, data & media)

applying the ROM from internal storage (not from an external SD card) -> reboot ROM -> reboot recovery

applying Gapps from internal storage (Webview is part of the Stock Gapps package, so you don't have to install that separately) & flashing SU

...and following [MENTION=4924800]CrazyWinner[/MENTION] 's solution, if getting the "setup wizard has stopped error" after booting into ROM - typing these lines via adb:

adb shell pm grant "com.google.android.setupwizard" android.permission.READ_PHONE_STATE

adb shell pm grant "com.google.android.gms" android.permission.ACCESS_FINE_LOCATION

adb shell pm grant "com.google.android.gms" android.permission.ACCESS_COARSE_LOCATION
[LG Optimus 4X HD] FaySmash:
Ok, thx, I'll try to format the complete filesystem
[LG Optimus 4X HD] csk1jw:
Due to the permission controls, starting with Marshmallow it is important that ROM and GApps being flashed in recovery without any reboot between them. This guideline is clearly spelled out by OpenGApps wiki and delta GApps OP. I don't know if "reboot recovery" can be considered acceptable, but for me I don't even need to consider it as CWM works out perfectly.

If you still keep the device and would like to try out modern AOSP ROMs, then please save yourself some troubles by using CWM recovery. Once the ROM and GApps are flashed using CWM, you can replace the recovery through fastboot with anything you wish after setting up Android on 1st boot.

$ adb reboot oem-unlock
$ sudo fastboot flash recovery ./your-recovery.img

Isn't that simple enough? You don't have to have CWM recovery to keep the ROMs functioning.
[LG Optimus 4X HD] FaySmash:
thanks for your response...will try and report. I totally hate CWM, it's like a virus, you just can't get rid of it without a pc nearby.
[LG Optimus 4X HD] Salman Al-Badgail:

[LG Optimus 4X HD] FaySmash:

thanks...cwmr worked...I dunno if this issue is releated to opengapps install scripts or twrp install queue...anyway thanks 4 your help [MENTION=535343]all[/MENTION]!! switched back to twrp and make a backup atm with working gapps ^^

[LG Optimus 4X HD] csk1jw:
New buid 20180122

New build is up, likely the final Nougat 7.1.2 build from Google AOSP.

For best experience, you should add

$ adb shell settings put global job_scheduler_constants fg_job_count=2,bg_normal_job_count=1,bg_moderate_job_count=1

This will serialize background jobs and limit foreground jobs to minimize impact to system load and memory footprint. This only needs to be done once after Android is fully booted and it will be saved in the settingsdb, just like any other settings.

A short question. Is the lack of nfc in the latest build is the case? It was useful.
[LG Optimus 4X HD] csk1jw:
There wasn't any change with respect to NFC in the latest build. The NFC on/off showed up in the Settings and Android Beam is available to use it, if enabled. NFC related logs are normal on the logcat.

BTW, I just tried Android Beam over NFC with another NFC phone. It works.

I haven't started working on porting Android 8.x, not sure if we can even make it there. It is a non-trivial undertaking, though. I would probably wait for other more experienced devs to make breakthroughs on legacy devices. At the moment, I have limited time and would prefer to port Nougat to several of my other phones/tablets.
[LG Optimus 4X HD] b886b:

[LG Optimus 4X HD] ze7zez:
Perhaps I hurried to ask the question.

However, I did not have the option "NFC" or "Android Beam" in the settings.

I was very surprised. :silly:

These options simply did not exist.
