[LG Optimus 4X HD] G4l4xio:
What do you suggest me then? And is answer no also for question can I flash new version of this ROM over older version which I have now?
[LG Optimus 4X HD] streambinder:
New build is up. Enjoy!
[LG Optimus 4X HD] csk1jw:
I highly recommend the modular gapps from deltadroid. You get to choose which apps to stay on the phone.

http://xdaforums.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368

The ROM update will wipe out system partition. If you install any gapps onto system partition, then you simply need to reinstall them after flashing the ROM. Typically, you can only install gapps onto system partition only by doing that from recovery. If you install gapps in data partition, then nothing will change. Play store updates and APKs will install onto data partition.
[LG Optimus 4X HD] G4l4xio:
I already installed some PA Stock gapps, 437 mb and everything is working great just some 4 minor problems.

1. Gallery is missing, but I've downloaded Gallery KK app that lets me see my pictures and videos just like stock app Gallery.

2. Can't remove google search taskbar found this way but it says it can brick my device so I'm scared to try it https://www.youtube.com/watch?v=DWy1OjlBfsQ can I do it on my lg 4x hd or there is another way to remove it?

3. Also I can't remove completely some apps like hangouts which I don't even use.

4. My laptop does not recognize my phone when I connect it via usb, but that's not problem I use Wi-Fi file transfer app.
[LG Optimus 4X HD] lckjosh:
Has anyone tried the latest build? How is it?
[LG Optimus 4X HD] asgz:
Why you install stock gapps, there is also options for nano or pico gapps, pico gapps mean is just google play.
[LG Optimus 4X HD] G4l4xio:
Because I kinda use too much stock apps and need them, used to them. All working perfectly, apps which I don't need/use are disabled, using nova launcher to hide google now search bar from home screen. Just one problem with all previous builds, my laptop can't find my phone when I connnect it via usb cable nothing happens it just charges, anyway to fix that? If not, no problem I use Wi-Fi file transfer pro app anyway.

And yes google play games app is a must for me, can't save any game progress without it and it comes only with all stock gapps.
[LG Optimus 4X HD] bilbo75:
Working fine for me. Smooth and fast. No blocking issues at the moment.
[LG Optimus 4X HD] AndreaFar:
I'm very interested in this ROM unfortunately tried months ago and there was some annoying problems.

Are the problem with GPS and freezes during the calls fixed?

NFC, and all sensor are working?

The TV out is working?

PS

Why don't include a summary of not working things and issues in main thread?
[LG Optimus 4X HD] bilbo75:
GPS is so and so for me. Some day better others not so good.

Calls are ok for me. Never had any problems.

Sensors in general work fine. Never tried NFC I don't use it.

I don't know about TV out.
[LG Optimus 4X HD] AndreaFar:
In the version that I have tested a couple of months ago, the GPS was unable to connect to the satellite (get only the partial position retrieved from the network).

You can confirm that now satellite GPS has been fixed and works?

The radio and the TV out (but this isn't a critical feature) were also broken

The NFC is another important feature for me, (to test is enough use an NFC tag reader app with the NFC label that Lg included in the box).

Unfortunately I haven't another phone so I cannot factory reset everything every release only to test what works or no.
[LG Optimus 4X HD] csk1jw:
gps.conf

If you have GPS issue, then try the attached gps.conf.

Replace the file in recovery:

adb shell mount /system
adb push gps.con /system/etc/
adb shell chmod 644 /system/etc/gps.conf

No one has reported if MHL works or not. If you have the cable, then please test it and report back to the devs.

Screen cast works, which is a much better alternative to MHL. and Chromecast can be cheaper compared to MHL cable.

FM-radio, really, nobody even bothers....:p

NFC is another less popular feature, but looking at the source, there isn't any hacks for NFC support, I believe it should be functional just like bluetooth. You won't have the LG Tag app, and it is very likely that the LG Tag app won't work even if you have a way to extract the APK. You will have better luck with Lollipop native NFC APIs. Personally, I always keep NFC off on my phone.
[LG Optimus 4X HD] AndreaFar:
in the older version gps fix hasn't worked, I don't know if now fix satellite correctly

to test nfc you can download any nfc reader from google play (I have never used original nfc app)

if someone can confirm that nfc and gps are fully working I will flash this rom to try mhl cable by myself (note that some months ago in a rapid test I haven't noticed that gps was broken because partially found position using network, unfortunately wasn't unable to fix position using satellite)

EDIT

In old posts I have read that unfortunately camera scan apps will never work because of grouper blobs but in euphoria work because that uses stock blobs... Why choose hacked grouper blobs? QR codes are very popular it's a pity that with this rom all these kind of features cannot be used anymore
[LG Optimus 4X HD] matthewstate:
MHL works without a hitch, just tried it on a tv :)
[LG Optimus 4X HD] bilbo75:
Thanks for sharing. :good: I will try it ASAP and I'll report.

Do you think that the most important thing is this conf file, or there are other factors that need improvements? GPS is never been very good for me with custom roms with this phone.
[LG Optimus 4X HD] csk1jw:
Well, I can't tell for sure, at least with this file, I feel that it's about the same as LG official euro-open v20c JB ROM. The LG gps.tegra blob is missing one interface from Lollipop GPS HAL.

Even with LG Offical euro-open v20c JB ROM, I had seen GPS failed to lock during navigation and the position indicator jumps off in huge distance instead of moving smoothly, which told me that it might be getting position from cell towers.
[LG Optimus 4X HD] G4l4xio:
I want to know how to connect my phone via usb to laptop, I mean I connect it but it does not show my phone on laptop. Other thing is when I power off phone (no option to restart phone in this lollipop) when I turn it back on, my phone ringtone is not saved, only notification ringtone for messages etc, so I need to set my phone ringtone every time I restart it via power off. On settings, sounds & notification, phone ringtone it says unknown ringtone...

Edit: Battery is amazing. 3:30h screen on time and still having 9% of battery. 10h Wi-Fi worked, 1h Chrome browsing, 1:30h Youtube application working ( some music mix with video playing that's in screen on time also), 1 hour of gaming Soulcraft THD (Tegra High Definition) game so it is a demanding game not some low graphics and not demanding game. On stock jelly bean my battery was 2h to 2:30h max and lagging everything from typing to chrome browsing 4-7 sec lags, phone is working perfectly fast now, like it's a new phone and yes screen brightness is on 25% always because I don't need more.
[LG Optimus 4X HD] csk1jw:
Check your USB computer connection setting.

Settings->Storage and tap on the 3 vertical dots on the upper right corner. Select the mode for USB PC connection, default should be MTP.

Most modern OS's (XP SP3 or more recent Windows, Linux distros etc.) supports MTP right out-of-box. Otherwise, try your luck with the LG United Mobile USB drivers. Google is your friend.

kernel update

This is for anyone who likes to try out my kernel build. Assuming [MENTION=5889675]streambinder[/MENTION] built the CM12.1 kernel as-is from the repo, here's the changlists:

- NOOP I/O scheduler, remove all other flavors.

- Disabled ZCACHE and CLEANSWAP

- Enabled Tegra SE HW crypto support

- F2FS update from Moto G LTE

- Advanced lowmemorykiller update from Moto G LTE with:

CONFIG_ANDROID_LMK_ADJ_RBTREE

CONFIG_ANDROID_BG_SCAN_MEM​

- FSync sysfs control ported from Franco grouper kernel. FSync is disabled.

Use LG fastboot to update the kernel in boot partition:

$ adb reboot oem-unlock
$ sudo fastboot flash boot boot0.img
$ sudo fastboot flash reboot

To re-enable FSync

$ adb shell 'su -c echo 1 > /sys/module/sync/parameters/fsync_enabled'

If you want to keep FSync enabled permanently, you need to unpack the boot image and ramdisk to update the init.x3.rc file to remove the following line.

write /sys/module/sync/parameters/fsync_enabled 0

You need to understand the risk of disabling fsync. I am not responsible for any data loss. Use it as your own risk.
[LG Optimus 4X HD] streambinder:
Of course, I did. Built upon cm-12.1, without any modification.
[LG Optimus 4X HD] G4l4xio:
[MENTION=5889675]streambinder[/MENTION] I need your help asap man, big problem occured. Nobody can get me on my phone with calls, it says my signal is full but sometimes it has ! on icon with full signal too. I tried to restart phone and first 5 minutes when someone call me they can get me and phone rings but after 5 minutes nobody can get me again, it says unavailable to respond call later.

Edit: Also when I restart phone all missed call messages and normal messages which people send to me come. That means I can't even get messages from people. On settings, data usage, cellular network settings, I can't choose network operators it says error while searching networks, can't even do it automatically. I am on T-Mobile network called bonbon, Croatia. I sometimes also get message sim card is locked no service.

---------- Post added at 01:00 PM ---------- Previous post was at 12:07 PM ----------

Thanks man it's working now!

Did all 2 steps which you mentioned and MTP was not turn on.
[LG Optimus 4X HD] csk1jw:
Are you using the latest build from streambinder?

These are exactly the RIL issues I had seen in the past before the fixed patches for cleaner RIL/GPS. The (!) on the signal icon means that your cellular data connection failed the Lollipop captive portal check and Lollipop will not use such connection. Usually, this won't impact GSM voice call/receive, unless your carrier may resort to voice-over-data sometimes.

Your 2nd issue, where nobody can call you, no missed call, SMS notification etc. until phone reboot, and I believe if you tried to make any calls, it will end immediately, is also another RIL issue which the fixed patches trying to address.

If you are not using the last 2 build from streambinder, then you should upgrade to the latest build.
[LG Optimus 4X HD] G4l4xio:
Magically fixed somehow, and yes I could not make calls either, I don't have or use mobile internet on this phone but it was turned on. When I turned it off and manually searched my carier (bonbon) which here they call it sister of tmobile it worked, on automatic search of network I was only finding tcom and connecting to it. It seems they are different network even if they are from same career, tmobile.

Edit: what does mean RIL? And yes I have 0 MB/GB to spend for mobile network, only using wifi.

kernel - fsync

Attach kernel patch for exporting fsync_enabled in sysfs node. By default, fsync remains enabled. Use init.x3.rc to disable fsync in ROM.

echo while gsm call

Hi!

This is my first public post. First of all I thank for all of you who taking effort to develop end help the community!

While I having a gsm call the other partner has echo problem. On my side it's very clear. It's true only if I use 5.x rom. on 4.x rom evertyhing is fine.

Does anybody else experiented this problem ?

I googled it and found the problem is exists for others (with other devices). Maybe it's related to the feature: High-definition voice calls, available between compatible devices running Android 5.1

Can I turn it off? The option that is mentioned at other forums is missing from the dialers's settings.

Thanks in advance
[LG Optimus 4X HD] csk1jw:
GSM voice calls are always crisp and clear for me, both from earpiece and speakerphone modes. I also use Motorola H730 BT headset on call sometimes.

Qr-Scanner

Hi,

first: thx a lot - good Job!:good:

secondly: Is there meanwhlile any solution for the issue with barcode/qr scanner (i.e. different kernel). Was anyone able to scan a qr-code successfully?

thx Detlef
[LG Optimus 4X HD] dunchann:
barcode

No, it doesn't work for me and I miss it too
[LG Optimus 4X HD] reimer.sb:
Hi,

where can I download that kernel, and is the qr-scanner possibly working with that modifications. (yes - I know its got something to do with the blobs, but its woth a question).

cheers
[LG Optimus 4X HD] bilbo75:
You have to download sources and compiling by yourself.

No luck with qr-code scan either. It's not a kernel issue, for what I know. This rom use the binaries from Nexus 7 device, and the interface to dialog with them is not perfect. If you need qr-code scan, you have to stick with official cyanogenmod, euphoria , stock rom or other rom with official LG blobs. That's it.
[LG Optimus 4X HD] InterrtuptoR:
Can i flash euphoria kernel over aosp? Will qr scaner work then?
[LG Optimus 4X HD] csk1jw:
No.
[LG Optimus 4X HD] bilbo75:
Kernel not compatible and anyway it's a matter of binary blobs. Not a kernel issue. You NEED a different ROM.
[LG Optimus 4X HD] 31kcir:
Hi,

I want my phone to automatically power on when it is being charged. However I have a hard time to do so.

Can anybody tell me (or give me a hint) where to find the file that plays the charging animation when the device is off? Or the charging animation itself so I can search all system files for that name? For samsung devices it would most likely be "/system/bin/playlpm" but since it seems to be device (and even rom?) specific I wondered if somebody knows where to find that file on this device and rom. There is a fastboot command for some LG devices to do that but it doesn't work for the p880, just like all the apps with that target i tested.

I'd very much appreciate any help.
[LG Optimus 4X HD] csk1jw:
Both are readily available with this ROM. If you don't get them, then I am not sure how the phone had been messed up. I suggest that you perform a full phone factory restore using LGMobile flash tools to LG stock v20 JB ROM. Then re-flash this Lollipop 5.1.1 ROM, if you wish.
[LG Optimus 4X HD] dunchann:
Then where is the source? I'm looking for changes what csk1jw mentioned in the earlier post and refered as "my kernel build".

Thanks
[LG Optimus 4X HD] bilbo75:
Did you try to check the first post??

You have to download the official sources and then apply the patch in the previous POST
[LG Optimus 4X HD] dunchann:
Yes I did.

I know where is the original source.

Yes I'm looking for the patch, but post #1133 doesn't contain any patch.

Post #1138 only contains patch for "fsync_enabled in sysfs node" and as I see doesn't conatin the six bulletpoints that are described post #1133

If you know where is the patch or what is the proper post please let me know!

Thanks for your help
[LG Optimus 4X HD] 31kcir:
I don't know if you got me right. If I start charging the turned off device, it shows the charging animation for a while and turns off then. I want it to boot instead of showing the charging animation. To accomplish that I need to know which file calls the charge animation so I can edit it to, instead, boot up android. I could find the path to that file for Samsung devices and for another LG device but both paths aren't the correct ones for the p880. For some LG devices (Nexus) there is a fastboot command to make the device boot when being charged, but it doesn't work for the p880 too.
[LG Optimus 4X HD] csk1jw:
This is the expected stock behavior. To turn on the device, you need to press the power button.

AFAIK, the charging battery animation is done at the LG bootloader, which you cannot change. If you change it, then your device will be soft-bricked until you perform a full device factory restore using LGMobile flash tools.
[LG Optimus 4X HD] 31kcir:
I'm not sure but I think I've seen charging animations with percentage on this device so it should actually be possible to edit them. Isn't this be possible with an unlocked bootloader?
[LG Optimus 4X HD] G4l4xio:
HELP!!!

Suddenly my phone is not recognizing my SIM card, on other phones that SIM card is working...
[LG Optimus 4X HD] G4l4xio:

The cellular network will be unavailable until you restart with a valid SIM card inserted.

It worked just fine till this morning and I did not do anything with phone :S.

[MENTION=5127019]MoltenMotherBoard[/MENTION]

Are the kernel updates from [MENTION=5799877]csk1jw[/MENTION] included in the latest version?

[LG Optimus 4X HD] peter_altherr:
well my experience is totally different with werewolf kernel v10 and lastest mmb rom for our beloved p880. i had a quite good responding system with mmb kernel and then installed werewolf v10 resulting in a really slow and laggy up to unusable phone. no matter what kernel tweaking i tried (using trickster mod). i also experienced serious ril problems because after a while phone was still showing antena with several bars pretending a good signal reception but no incoming call reached the phone nor could i make phone calls, send text message or make use of the data connection. a restart was required and then the same game after a while. so i reflashed the whole mmb to get back the mmb kernel.

Can anyone tell me what is the difference btw this AOSP and CM12.1 for the p880 from laufersteppenwolf

http://xdaforums.com/optimus-4x-hd/orig-development/dev-unofficial-cm12-p880-t2934360

as I know CM is AOSP or?
[LG Optimus 4X HD] b886b:
To me AOSP is like a vanilla android system with minimal features and stuff, it is like a pure rom. However, CM is packed with additional features and have more apps pre-installed in the rom. Just choose one that suits you best.
[LG Optimus 4X HD] Aei10:
Hi guys I have the Cm11 at this time, do you think that by using one of this ROM I could have some improvements, or the ROMS are still not reliable?Take into account that this is my only phone :)
[LG Optimus 4X HD] b886b:
Regarding performance, I think the roms that is kitkat are better because lollipop is kind of resource hungry. But if u really want to try out lollipop then in my opinion this rom and the Euphoria ones are the best shot as u can see they are pretty up-to-date and most of the reviews are positive.
[LG Optimus 4X HD] Aei10:
Hi guys I would like to try this rom since I am having problems with CM11 in particular with respect to calls and network operator. So I have clockwork recovery 6.0.4.5 and CM11, I have already made a backup in recovery mode in order to be sure that I can get back to this rom. But I would like to ask, sorry for the very stupid questions, what are the steps I have to follow to install the rom?And where I can find gapps?
[LG Optimus 4X HD] asgz:
* wipe cache partition

* wipe data/factory reset

* advanced > wipe dalvik cache

* mount & storage > format /system

install rom

install gapps

Gapps depend of your choice. I am installing open gapps and nano vers. Here is the link for open gapps http://opengapps.org/
[LG Optimus 4X HD] Aei10:
Excuse the question, the platform for the download of gapps is ARM right?

Furthermore, since I am reading that CMW 6.0.4.7 is giving problem and , maybe also CMW 6.0.4.5, is there anyone who has tried out to install gapps with CMW 6.0.4.5?
[LG Optimus 4X HD] matthewstate:
It's ARM :)
[LG Optimus 4X HD] Aei10:
As for the recovery? I have read throughout the post that it's suggested to use CWM, but the version 6.0.4.5 may undergo problems with open gapps, any suggestion?
[LG Optimus 4X HD] Aei10:
Tried out with open gapps nano, everything works perfectly, I have realized no ROM I have had before( stock rom, CM 10, CM11) was EVEN COMPARABLE to this one.I haven't tried to call yet, but I feel I can say this is the best ROM for this phone. The developers are gods to me, really really great job guys, thanks very much :)
[LG Optimus 4X HD] skrajnik:
Test some more and report back,please.

Looking for decent rom for years :)

Speed,no lags,battery is all I ask :)
[LG Optimus 4X HD] Aei10:
I think you want too much :) Anyway, I can say that this ROM is more battery consuming than the CM11 but this is a very fair prize because this ROM is the fastest and the most stable. I have only experience with this one and the CM11 , but maybe you can try the AOSP 4.4.4 and see if it's better than CM11, but like I've already said I prefer this one to CM11
[LG Optimus 4X HD] Aei10:
Hi guys, just a curiosity. Are you going to develop android 6 for this phone?
[LG Optimus 4X HD] streambinder:
Nope. Or at least me, I won't. I no more own this device: development would be so much slower and harder.
[LG Optimus 4X HD] Aei10:
Thank you very much for what you have done :). If you tell me the name I think I will buy your phone so I will get all the newest ROM :)
[LG Optimus 4X HD] streambinder:
Thank you mate, glad to hear that. :)

I now own a Xiaomi Mi4C, but I stopped working on Android - as I really do not have time, it gets totally spent on my job and university.
[LG Optimus 4X HD] Aei10:
Good choice :)

Anyway I don't know if you can help me I would like to know two things

1 Is there a shortcut way to reboot the phone?, because long press of the up button only leads to shut down the phone.

2 Since sometimes it happens that the phone loses connection to the network, but it shows only problems with the network connection and doesn't try to reconnect by itself, is there a way to make this reconnection possible without turning off and then on the phone every time?

3 Since I know that the operator of my network it's not that good in terms of reception and sometimes even if the phone shows that the connection is present (3g symbol), in reality there is none, there is a way other than trying the browser if the phone is connected or not? Even though it may seem a stupid question, sometimes I feel a little bit anxious since sometimes I don't see any messages, while in reality there are some.
[LG Optimus 4X HD] streambinder:
1. The only way is to use mods from Xposed.

2. Tap for airplane mode, wait 10s, untap it. It should reload RIL.

3. You could try many apps to check your connection. For example - the first one that got in my mind - in Terminal Emulator, you could execute: ping 8.8.8.8 . Reading and understanding its output shouldn't that difficult.
[LG Optimus 4X HD] AndreaFar:
Any way to activate camera scan features in this ROM???

The scan of QR codes, barcodes, images etc. pointing the camera is a very popular smart function. Also the payment system of my bank use this feature to simplify the payment.

Why you have chosen these blob with broken camera scan functions?
[LG Optimus 4X HD] laufersteppenwolf:
Alright guys, when we had RIL issues on CM11 last year, we noticed that the RIL actually works also without overriding it with our X3RIL class. What this means is that it may be worth a shot trying to not override it but to use the default RIL.

This would have to be done like this: https://github.com/P880-dev/android_device_lge_p880/commit/9532b2b400752831736362077a1af19b26f1849d

However, it also should be enough to just comment out the build.prop line (https://github.com/P880-dev/android...752831736362077a1af19b26f1849d/system.prop#L9)

I have no idea how's it gonna work, so try on your own risk ;)
