First of all, I'm not the maintainer of this device, I just created this thread to have a central place where everything related to this rom can be discussed, and give other users with problems good support

WARNING! This ROM is for the E975 variant only!

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit the Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Current known Bugs (Nightly 03/06/2015):
  • SIM Pincode doesn't get accepted even though the code is correct. The bug report on this issue can be found here. The currently known workaround for this bug is also found in the FAQ section in this topic.
  • If you encounter a bug please tell me so I can try to track it down and tackle the problem! (Just leave a message here, or file a bug report using the button above.)

CM-12.1 Install Guide

Note: CM for Optimus G International is provided with no warranty. You are installing this software at your own risk. You may be violating your warranty.

Download CM-12.1 and gapps-lp (optional) zips and put in /sdcard


Please verify the md5sum to be sure you got the right one.

Before you install CM-12.1: Preparation (First three are optional. If you want to start fresh, these can be skipped)
  1. Install AppBak from Market, run it and save a list of all your apps.
  2. Install SMS Backup and Restore from Market, run it and backup your SMS history.
  3. Install Call Logs Backup and Restore from Market, run it and backup your call log history.
  4. Boot into TWRP Recovery (Instructions below). Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.
WARNING: Many apps will Force Close crash if you restore data from a previous ROM.

Install
  1. Use TWRP Recovery 2.8.6.0. Install Howto:
    • Make sure you have rooted your current Android ROM with any of the methods floating around this forum.
    • Install Freegee from the PlayStore
    • Run Freegee and accept root permissions
    • Make a EFS Backup and store it somewhere safe (Freegee saves it in the internal storage by default, you should copy it to a USB drive for safekeeping)
    • Install CWM from Freegee, and if asked use the Mako unlock method to unlock the bootloader.
    • Boot to CWM Recovery
      • Power off your device.
      • Wait a few seconds.
      • Boot to bootloader by pressing the Volume UP and Power Button at the same time for 2-3 seconds until the Google Logo appears on the screen.
      • In bootloader choose 'Recovery Mode' using volume up/down buttons to swap selections, and power button to select the highlighted option
      • Release the buttons and press them again until the Recovery Screen appears.
    • Choose 'Install zip', Select 'Choose zip from /sdcard', browse to where you saved twrp-2.8.6.0-geehrc.zip and flash twrp-2.8.6.0-geehrc.zip
    • Reboot to Recovery from the 'Advanced Menu'
    • Warning: Only use this recovery to flash CM-12.1. Otherwise, you risk bricking your phone!
  2. In TWRP choose 'Wipe', then 'Swipe to Factory Reset' and go back to the main menu.
  3. Choose 'Install', browse to where you saved cm-12.1*.zip, select the cm-12.1*.zip and 'Swipe to Confirm Flash'.
  4. (Optional) Flash gapps*.zip. You must flash gapps after every upgrade to CM-12.1 since /system is formatted, wiping your previous add-ons.
  5. Reboot phone.
  6. After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
  7. Warning: Do not restore backup data of system apps!
    • If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
    • It seems that restoring backups can also break Calendar sync.

Upgrades
Upgrades from previous versions of CM-12.1 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between CM-12.1 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.

FAQ:
Q: How the heck do I get root?
A: Goto Settings and About Phone. Tap Build number 7 times. Go back and enter
Developer options. Change Root access to desired method.
Q: How to get around the PIN not accepted bug for now?
A: A workaround for this bug, until it has been worked out, is to just disable the PIN security for your SIM Card.

Other Issues?
Use this for obtaining logs.

Hello @akahroba, it's been some time now since I've been busy with development for this phone. Currently unfortunately I don't own this device myself anymore since my own phone broke down:(. Now I own a LG G2 International d802. Luckily I have access to a e975 to test some things from time to time. Unfortunately not enough to get fully developing for this device. Also my time for developing is very limited as my proffession is maritime officer, so away from home a lot.

oh, that's bad. You mean it fell down and broke into piececs? :/
There's an ongoing Ubuntu porting project by @mordesku that I was thinking you might be able to help.

My phone is still in onze piece, but unfortunately it wasn't very water resistant. The phone fell into the toilet bowl and I think shorted out. I tried to dry the phone completely and tried a new battery as wel but the phone didn't give any sign of life anymore. But I will take a look in the Ubuntu topic and see if I could be of any help:).

Can somebody supply me with the latest logs of a running cm12.1 nightly (preferably latest). Using the app SysLog from the PlayStore. That way I can try to pinpoint where the Sim probleem might be coming from. I suppose the RIL should be altered to get full CM12.1 compatibility.

I may have found the problem for the 'SetupWizard' crash.
In the process of bugtracking I set selinux to 'permissive', so I wouldn't have to bother SeLinux during bugtracking.
Strangely after setting Selinux to permissive I was able to clear the 'SetupWizard' without any troubles.
So my suspicion is there may be some permission problems due to Selinux.
I'll investigate this matter a little more in the coming days.

Update 1: I can confirm I was right in my findings.
Selinux blocked some requests which were needed for the SetupWizard.
I'll upload the patches to the CyanogenMod Gerrit and then hopefully they will be pushed upstream very soon.
The next thing to investigate will be the Pin problem. Unfortunately this doesn't seem to be a permission problem.
I've seen some hints in the logs which may give some clues on what is going on, but it's too early to base any conclusions on those findings.

Update 2: Yesterday (01/06/2015) my fix for the SetupWizard had been merged.
Unfortunately the fix didn't make it in time for the 01/06 nightly.
Today the fix will make it into the 02/06 nightly.
So I would say happy flashing tot everybody, and please report back you're findings.

Greetings PsychoGame

Good job mate. About the sim pin I think @dadi11 has already fixed it.

The trouble I am caught up with is:

My sim card / network keep appearing and disappearing in status bar (they appear for about 0.5 second and then disappear). I have no network/sim coverage. Same problem is with MOKEE 51.1 as well.

On stock kitkat v20A, my phone has no problem at all and also on CM 11 as well as MOKEE 44.4.

How can I fix this issue? I can't accept sim pin settings.

P.S My simcard is perfectly fine in other phones or KitKat/JB on my E975.

It has been 5 days since this issue was last updated. In an effort to keep the Nightly Regression tracker as clean and up-to-date as possible, we ask that users reporting regressions check in every few nightlies to comment on an issue. The reported problem may or may not have been worked on directly, but we frequently merge code from outside sources that may have fixed or changed this issue.
That being said, is the above problem still an issue on the latest nightly?

For those of you who have experience in custom LGG roms:
- will this work for CM12 snapshot build?
- what differs the CM12 and CM12.1 versions for Gee? is it worth updating to nightly, knowing it has some issues that were solved in the snapshot release?
- how big is the increase in performance, if any, compared to stock?

I'm currently making a backup of all apps with TI Backup, but what if I want to have a mirror of my current ROM in case I wanted to go back?

I have done many things to customize my previous Xperia Neo V phone, and was happy with LGG stock/rooted till now. It got laggy, looks old (compared to the Moto G for instance) and it is just a bit boring being stuck with stock ;)

    CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit the Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    Current known Bugs (Nightly 03/06/2015):
    • SIM Pincode doesn't get accepted even though the code is correct. The bug report on this issue can be found here. The currently known workaround for this bug is also found in the FAQ section in this topic.
    • If you encounter a bug please tell me so I can try to track it down and tackle the problem! (Just leave a message here, or file a bug report using the button above.)

    CM-12.1 Install Guide

    Note: CM for Optimus G International is provided with no warranty. You are installing this software at your own risk. You may be violating your warranty.

    Download CM-12.1 and gapps-lp (optional) zips and put in /sdcard


    Please verify the md5sum to be sure you got the right one.

    Before you install CM-12.1: Preparation (First three are optional. If you want to start fresh, these can be skipped)
    1. Install AppBak from Market, run it and save a list of all your apps.
    2. Install SMS Backup and Restore from Market, run it and backup your SMS history.
    3. Install Call Logs Backup and Restore from Market, run it and backup your call log history.
    4. Boot into TWRP Recovery (Instructions below). Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.
    WARNING: Many apps will Force Close crash if you restore data from a previous ROM.

    Install
    1. Use TWRP Recovery 2.8.6.0. Install Howto:
      • Make sure you have rooted your current Android ROM with any of the methods floating around this forum.
      • Install Freegee from the PlayStore
      • Run Freegee and accept root permissions
      • Make a EFS Backup and store it somewhere safe (Freegee saves it in the internal storage by default, you should copy it to a USB drive for safekeeping)
      • Install CWM from Freegee, and if asked use the Mako unlock method to unlock the bootloader.
      • Boot to CWM Recovery
        • Power off your device.
        • Wait a few seconds.
        • Boot to bootloader by pressing the Volume UP and Power Button at the same time for 2-3 seconds until the Google Logo appears on the screen.
        • In bootloader choose 'Recovery Mode' using volume up/down buttons to swap selections, and power button to select the highlighted option
        • Release the buttons and press them again until the Recovery Screen appears.
      • Choose 'Install zip', Select 'Choose zip from /sdcard', browse to where you saved twrp-2.8.6.0-geehrc.zip and flash twrp-2.8.6.0-geehrc.zip
      • Reboot to Recovery from the 'Advanced Menu'
      • Warning: Only use this recovery to flash CM-12.1. Otherwise, you risk bricking your phone!
    2. In TWRP choose 'Wipe', then 'Swipe to Factory Reset' and go back to the main menu.
    3. Choose 'Install', browse to where you saved cm-12.1*.zip, select the cm-12.1*.zip and 'Swipe to Confirm Flash'.
    4. (Optional) Flash gapps*.zip. You must flash gapps after every upgrade to CM-12.1 since /system is formatted, wiping your previous add-ons.
    5. Reboot phone.
    6. After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
    7. Warning: Do not restore backup data of system apps!
      • If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
      • It seems that restoring backups can also break Calendar sync.

    Upgrades
    Upgrades from previous versions of CM-12.1 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between CM-12.1 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.

    FAQ:
    Q: How the heck do I get root?
    A: Goto Settings and About Phone. Tap Build number 7 times. Go back and enter
    Developer options. Change Root access to desired method.
    Q: How to get around the PIN not accepted bug for now?
    A: A workaround for this bug, until it has been worked out, is to just disable the PIN security for your SIM Card.

    Good job mate. About the sim pin I think @dadi11 has already fixed it.

    Thank you for the information @akahroba.
    If I look at the device code, then it looks like they have a completely different device codebase.
    I'll ask @dadi11 about this.

    I may have found the problem for the 'SetupWizard' crash.
    In the process of bugtracking I set selinux to 'permissive', so I wouldn't have to bother SeLinux during bugtracking.
    Strangely after setting Selinux to permissive I was able to clear the 'SetupWizard' without any troubles.
    So my suspicion is there may be some permission problems due to Selinux.
    I'll investigate this matter a little more in the coming days.

    Update 1: I can confirm I was right in my findings.
    Selinux blocked some requests which were needed for the SetupWizard.
    I'll upload the patches to the CyanogenMod Gerrit and then hopefully they will be pushed upstream very soon.
    The next thing to investigate will be the Pin problem. Unfortunately this doesn't seem to be a permission problem.
    I've seen some hints in the logs which may give some clues on what is going on, but it's too early to base any conclusions on those findings.

    Update 2: Yesterday (01/06/2015) my fix for the SetupWizard had been merged.
    Unfortunately the fix didn't make it in time for the 01/06 nightly.
    Today the fix will make it into the 02/06 nightly.
    So I would say happy flashing tot everybody, and please report back you're findings.

    Greetings PsychoGame
