Hi im new and im wonder, if i flash it how can i update the rom later? without losing all my stuff!
[LG Optimus 4X HD] TimBirdy:
If you want to update the rom you just need to flash the "new version" zip-package via recovery or you use the ota updater in the Settings (don't know wether it already works in this rom). Either ways, you won't loose your stuff! :)

If you want to flash a different rom (or different android-version) you need to do a factory reset, wipe cache, ...etc.

Then you loose your stuff. In this case I recommend "Titanium Backup", as you can backup your apps including the data.
[LG Optimus 4X HD] Raffaele85:
[MENTION=5889675]streambinder[/MENTION] when can we test the new ROM?
[LG Optimus 4X HD] streambinder:
If [MENTION=4924800]CrazyWinner[/MENTION] confirms it's stable enough, I will directly put it in usual download list. ;)
[LG Optimus 4X HD] Raffaele85:
Great, thanks
[LG Optimus 4X HD] sunsettrack4:
It's stable enough - the camera app works without any issues, and in general, the system can be used as a daily driver (my review after a few days of testing).

The 3G/Wifi geolocation problem still exists...
[LG Optimus 4X HD] streambinder:
Thank you, mate! ;)

Great ROM

I've been using the CM11 ROM since it appeared, and just changed to this one yesterday, and I've got to say it's really good. My battery is better (when in sleep the line is now practically horizontal) and the whole experience/performance is a lot smoother, now I'm hoping to see if I still get the loss of network and asking for pin when the battery is around 20% like happened to me in CM11 or not!

On the down side, I kind of miss the ability to unlock the phone with the volume button (the apps that allow it kill the battery) and the lack of control on the Lock screen, have got to go get a Lock scree app :p

And I've noticed it really lags with some apps.. Gmail and Chrome are unusable, but I already used faster substitutes so no harm.

And a few of the apps I backed up I can´t use with my old data, as it crashes the app, but worked fine once I erased it and installed it without the data :(

Overall after 2 days of use, very happy with my first AOSP experience. Good Work :) Thanks a lot!

hi

i just installed this rom on my phone and everything seems to work great but i don't have any applications, google play or other..

is it normal or did i do something wrong?

thx
[LG Optimus 4X HD] sunsettrack4:
You have to flash a GApps package for using Google Play etc.

[LG Optimus 4X HD] Kaioh_shin:
hey there

I am also considering trying this ROM.

My main problem is the lack of VOLUME button to wake device, you see my power button is kinda broken and only works if I push insistently on it.

Hope to see this in the next build!

Hi

I have tried an easy update (dirty flashing) from 5.1 version to New build - 5.1.1_r1 branch code based, and the result was a disaster. So, I made a clean fresh install and everything seems to be OK now. I will test it for a few days and report.

Congratulations Streambinder for this job. This AOSP rom is for the moment the only one with an acceptable stability for a daily use.:o
[LG Optimus 4X HD] TimBirdy:
Hey ;)

1) You don't need to do anything with the bootloader. All you need is an unlocked one

2) CWMtouch recovery is alright (I also use CWMtouch recovery and i have no issues)

3) I'm not 100% sure what you're asking ;)

- Copy Personal files from the internal sdcard to your computer

- Apps & data can be backed by titanium backup (make sure you set the backup path to external sdcard or copy the backup files also to our pc)

- If you want to update, you have to flash! the new zip-package!

4) Just make sure the Gapps are the right ones (for android 5.1/5.1.x) the different gapps-package differ, as they include more or less google software (I prefer the minimal-packages, as I don't need hangouts, google+...)

For Root I would download the zip from the official website and then let the SuperSu App (from the Playstore) do an update

5) I have not tested GPS yet (will test it after I updated to the latest Version of this Rom)

[LG Optimus 4X HD] BBorrisR:

All of the sudden miscellaneous is killing my battery :(
[LG Optimus 4X HD] abhi08638:
Miscellaneous isn't a battery drainer itself. Its rellimgnyou that there's something keeping your phone awake like a wakelock or app alarms. Use wakelock detector and BBS to find out what's causing it. You can find both by googling them if you don't know what they are
[LG Optimus 4X HD] tasanhalas:
I already have wakelock detector with no red flags showing, I'l try BBS
[LG Optimus 4X HD] TimBirdy:
I tried CWM and TWRP to flash the latest Version of this ROM. Both worked just fine. TWRP has a better interface and some cool extra features (like flashing several zips automaticly in a row). In my experience both, CWM and TWRP are 100% stable. imao

If you stick on some old backups you might not change your recovery as TWRP can't deal with CWM-Backups (and the other way round).
[LG Optimus 4X HD] tasanhalas:
My waether Clock Widget was a big culprit, but still was no the answer. Miscellaneous dropped from 30+% to 18%, now according to wakelock the bigest problem is the System UI with 61x 4s in about 12 hours

Screen Pinning

The Rom is amazing but the Screen Pinning from security menu doesnt work properly, after i pin a screen i can´t unlock it, or maybe im doing something wrong! if any body can tell me would be nice.. thanks
[LG Optimus 4X HD] the_odyssey:
My LG 4X HD is my first and only smartphone , and this rom is the first rom I ever installed on it. Working great already.

Was getting quite frustrated with stock JB, and all the stuff running in the background eating battery and RAM, slowing down the phone. I have none of that with this rom. Using it daily now as my new android OS. Keep up the great work, I´ll be updating and report back on new versions - looking forward!

When I try to take a picture using flash it takes 10 seconds between focus and the flash to come out. Has anyone a tip about this issue?

[LG Optimus 4X HD] arx-7-arbalest:
You have to change the mac adress in bcmdhd.cal

Install a file manager, set "write" permissions for the /system folder, then open /system, etc, wifi, bcmdhd.cal.

I change only the last number (it's 38, i put 39), it works flawlessly :)

[LG Optimus 4X HD] csk1jw:
Any reason why fstab.x3 does not include journal_async_commit as the mount option for /data and cache partition? LG stock JB has it, and this ext4 option seems to improve file system performance from googling.

[LG Optimus 4X HD] streambinder:

Hi, can I install the Theme Chooser of Cyanogen ROM ?

If so, how can I do ?

Thank you and please forgive me for the OT .
[LG Optimus 4X HD] TimBirdy:
No, you need the cyanogenmod launcher which is necessary to use Canogenmod themes (doesn't matter wether you get these from Playstore/Theme Chosser/elsewere...).

I think it is not possible to install the cyanogenmod launcher(i think it is called "Trebuchet") with this rom.

If you want to use CM themes, you might want to install another ROM like CM12.1, Ressurection Remix or BlissPop. Be aware as these roms may not be as stable as the aosp, but BlissPop (which i currently use) works quite well.
[LG Optimus 4X HD] BOli3:
Thanks, but I think it is just a matter of launcher because when I was with Euphoria I used Nova Launcher.

I would change the theme, but I can not remove this magnificent ROM :D.
[LG Optimus 4X HD] Shadowghoster:
For the ability to use cm-themes there must be a whole bunch of code implemented on rom-side just like for RRO. Because this is a pure aosp that will never happen.
[LG Optimus 4X HD] varadinum:
There is no design! So it is! AOSP is not for children! [emoji23]
[LG Optimus 4X HD] BOli3:
Yes, once a long time ago.
[LG Optimus 4X HD] csk1jw:
Thanks. I could anyway try this out by unpacking the boot.img to update fstab.x3, and then flash the boot.img using LG fastboot.

I looked into the kernel source codes and it seems that it already support f2fs. Hopefully, someone will make a recent CWM and TWRP recovery with f2fs for our device.
[LG Optimus 4X HD] csk1jw:
Looking at how f2fs had breathed new life into the aging Nexus 7 (2012) which shares a lot of similarities with LG P880, I hope someone can revive f2fs support for LG P880. This ROM already support f2fs, but fsck.f2fs is not available. Is it possible to include the latest f2fs-tools into the coming release?

Can someone also provide CWM or TWRP recovery with f2fs support?
[LG Optimus 4X HD] csk1jw:
The ext4 mount option "journal_async_commit" does improve the file system. I felt the apps are starting faster. I think we should keep this.

Here's the reference from Linux testing:

http://www.raid6.com.au/posts/fs_ext4_external_journal/

However, not sure why CyanogenMod removed it for Qualcomm builds. I think it is natural that performance enhancements in file system may introduce slight risk for unreliable media.

http://review.cyanogenmod.org/#/c/47856/

In my opinion, if LG stock ROM has it, we should keep it.

Anyone know which ROM has fsck.f2fs?
[LG Optimus 4X HD] the_odyssey:
I seem to have a bug in the stock calendar app. It continually asks for a google account, and doesn´t seem like I can put in the account registered on the phone.

Also has the "pin-app" bug. When pinning an app, it is impossible to remove the pin.

Been using the ROM for two weeks now and still running very well. Definitely prefer this one to the LG stock JB, so much less fuss.
[LG Optimus 4X HD] csk1jw:
Finally, I am able to migrate /data and /cache to f2fs successfully on this ROM.

f2fs migration

[MENTION=5889675]streambinder[/MENTION]: If you build this ROM from source, then I think all you need to do is to include the latest CyanogenMod f2fs-tools available at:

https://github.com/CyanogenMod/android_external_f2fs-tools/tree/cm-12.1

And update fstab.x3 to include f2fs support for /data and /cache. I extracted them from fstab.grouper from the latest cm-12.1 nightly for Nexus 7 (2012).

/dev/block/platform/sdhci-tegra.3/by-name/UDA /data f2fs noatime,nosuid,nodev,nodiratime,discard,inline_xattr,inline_data,inline_dentry wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/FOT
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data ext4 noatime,nosuid,nodev,journal_async_commit,barrier=1,data=ordered,noauto_da_alloc,errors=panic wait,check,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/FOT
/dev/block/platform/sdhci-tegra.3/by-name/CAC /cache f2fs noatime,nosuid,nodev,nodiratime,discard,inline_xattr,inline_data,inline_dentry wait,check
/dev/block/platform/sdhci-tegra.3/by-name/CAC /cache ext4 noatime,noauto_da_alloc,nosuid,nodev,journal_async_commit,nodiratime,barrier=0,errors=panic wait

The steps that I followed is quite complicated since I am not able to build successfully from source yet. I will try to describe it at my best.

*PLEASE do proper backup as all data will be lost, if you care about your data*

Tools/Environment pre-requisites

- Linux box with adb and fastboot (I used Ubuntu 14.04LTS)

- Android BOOT.IMG/INITRAMFS packing/unpacking tools

- SDAT2IMG python script to obtain SYSTEM.IMG

- Official CWM recovery 6.0.4.5

- Latest CM-12.1 nightly for Nexus 7 (2012)

1. Extract mkfs.f2fs and fsck.f2fs from CM-12.1 nightly for Nexus 7 (2012)

- mkfs.f2fs from boot.img

- fsck.f2fs from system.img

2. Flash CWM recovery

3. Enter CWM recovery with "adb shell setup-recovery" follow by "adb reboot". *DO NOT* use the button combo PWR+vol_down.

4. Run "adb push mkfs.f2fs /sbin"

5. Run "adb shell" and format /data and /cache

# mkfs.f2fs -t -d1 /dev/block/platform/....../UDA
# mkfs.f2fs -t -d1 /dev/block/platform/....../CAC

6. Mount /system and exit adb shell

7. Run "adb push fsck.f2fs /system/bin/"

Reboot and you should have f2fs on /data and /cache. You can use "adb shell dmesg | grep -i f2fs" to check it.

*WARNING*WARNING*

Once the migration is done, NEVER EVER enter recovery using button combo "PWR+VOL_DWN". Use step #3 from above. Don't ask me why, I think this is a bug in LG bootloader. Otherwise, your /data will be corrupted and on next boot you will automatically end up with a fresh factory reset device with a freshly ext4 formatted /data.
[LG Optimus 4X HD] Alunduyn:
I just downloaded this for my GF's phone + PA stock gapps from TWRP. Would be great, if she just could turn the screen off.

I searched a little and can't find anyone relating to this issue. The phone just can't turn off the screen. If I do it via power button, it vibrates and turn on again in less than 1 second. If I let it turn off by timeout, it vibrates and turns on in less than a second.
