[ROM][UNOFFICIAL][N/O][F500,LS991,H81x,US991,VS986] LineageOS 15.1/14.1

[ThePiGuy]

Introduction

LineageOS is a free, community built, aftermarket firmware distribution of android, which is designed to increase performance and reliability over stock android for your device.

Requirements

• Your device need to be unlocked either officially (h815 international or h811) or by UsU
• Your bootloader stack should be on MM 20p (20x for H811) or higher! (see FAQ #20 for how to upgrade your bootloader stack).
  .... and for your convenience I have even created TWRP flashable files for that here
• in particular that means this thread is for:
  F500 (UsU'd)
  H810 (UsU'd)
  H811
  H812 (UsU'd)
  H815 (official unlocked or UsU'd)
  H819 (UsU'd)
  LS991 (UsU'd)
  US991 (UsU'd)
  VS986 (UsU'd)
• Latest TWRP - PREVIEW build: click
• Do a full Nandroid backup before doing anything!

Installation Instructions

1. This single very first step is for UsU'd devices only:
   If you have ever flashed the UsU baseband package: Clean flash the modem partition from your backup in TWRP.
   If you do not know if you ever flashed it simply flash your modem partition again and you can be sure. This can't do any harm.
   If you have no backup:
   - TWRP flashable MM modems (N might not work)
2. Full clean install as described here (FAQ "#2") is highly recommended. DO NOT REPORT ISSUES when you have skipped that step!
3. Flash LOS
4. Optional: Flash GApps (8.1 - ARM64 for LOS 15.1, 7.1 - ARM64 for LOS 14.1) if you like
5. Optional (if you want root): Flash the official LOS root-addon (addonsu-15.1-arm64-signed.zip or addonsu-14.1-arm64-signed.zip) or Magisk (do not report issues if you have Magisk installed though!)
6. Boot (will take a bit on first boot!!!)
7. Enjoy

Update Instructions

To update from a previous version of my rom:

• If it is an old version of the rom, it is recommended to do a clean flash - Be aware that your data will be deleted
• If it is a relatively recent version, a dirty flash should be ok - wipe cache and dalvik cache and then flash on top of your current installation - This keeps all your files

Current Issues

For a current list of all issues including possible workarounds:

• Open issues
  
• Issues with workarounds available

Summary (again check out the above linked issue tracker for a current state):

• Bluetooth calling FIXED!
• Flashlight icon on quick toggles FIXED!
• SIM pin unlocking (Ril works, better to use an unlocked sim card for now) FIXED!
• Magisk when encrypted - state UNKNOWN
• Permissive SELinux FIXED!
• Probably more undiscovered bugs

Building from source

If you want to build this from source, follow the LG H815 build guide (replace H815 with H811 if needed). Immediately before the "repo sync" step, copy our local manifest (https://github.com/Suicide-Squirrel/local_manifests/blob/los-15.1/roomservice.xml) into the .repo/local_manifests/ folder. Now run repo sync.
Then miss out breakfast and proprietary files steps before continuing with Jack memory optimisations

  Introduction
  
  LineageOS is a free, community built, aftermarket firmware distribution of android, which is designed to increase performance and reliability over stock android for your device.
  
  Requirements
  

  • LG G4 H815/H811
  • Latest MM firmware for H811 and latest Nougat/MM firmware for H815
  • Latest official TWRP or the latest TWRP preview from steadfasterX's server - This prevents the error 7 from appearing
  • For UsU devices, follow @steadfasterX's instructions for TWRP

  Installation Instructions
  
  

  1. Download appropriate zip for your device along with any additional modules such as gapps (arm64 android 8.1 needed)
  2. Recommended - Create a full nandroid backup to allow you to restore to your previous OS if needed
  3. Wipe system, data, cache and dalvik cache - Be aware that this WILL remove your currently installed OS and wipe your apps and most data
  4. Flash the lineage zip, followed immediately by gapps if applicable
  5. Reboot into system and wait for boot

Great work!
Need more stability to have a try but following it closely!
Thanks a lot.

 

[zeduck]

Good job!
I missed Lineage OS.
Is encryption working?

 

[aha360]

YOU, @ThePiGuy, built this (with help from others)? Well done man.

Good luck and Godspeed man

Yes it is

 

[hteles]

Yes it is

Is it trimming working with encryption ( fstrim -v /data ) without the error transport endpoint not connected?
Thanks!

 

[kessaras]

talk to @codeworkx.
if your commits you added are clean and crystal clear of what you did and you kept authorship, maybe you should update the official and get some logs to them to also help you.
Minor bugs of audio and maybe some props to make the camera function correctly are not hard bugs. Me i do not have the time sorry. I do not even have the time with AOSCP now that im working so much :/

Great job keeping LOS on this device. I'm holding on to it as I still find it fast and useful.
While there is a lens on the audio configuration it would be awesome to see this phone enabled for hires audio (up to 24bit / 192KHz) under LOS. I know people are skeptical of the difference but DAC is able to do this and it should simply be an edit of the relevant audio_policy_configuration.xml(?) file to enable the extra sound profiles above 16/48.

I have no idea (give it a go if you want )

First things first, got to get the audio working in the first place . And also, nobody seems to have seen the error that it kicks out in the logcat, so it might take a while to get it working - I'll try porting the cm-14.1 trees to lineage-15.1 rather than porting oreo cypheros trees to see if that makes a difference

@ThePiGuy what are the known bugs for this rom?

@ThePiGuy what are the known bugs for this rom?

All in the title post above (under Current Issues). Basically audio is fully broken (so this is purely testing at the moment - not suitable for a daily driver), camera is broken along with the lineage voice and screen recorder crashing.

All camera apps ? Even Google s ?
If Google's work, then it's just a prop.
Also yes that's normal since Los uses snap and maybe it needs different props , it may needs a couple different things to call for build and some overlay settings in a config.

The other Los developers should already know how to make this work since they have ported many phones.
Me I never developed in los, I don't know.

I haven't tested any others yet. I'm mainly focusing on the audio at the moment

 

[michael_0394]

Great job bringing LOS back to life for the G4!

 

[Schwarzie2k]

Thanks for your effort! I will monitor this Thread closely and hope you soon find the audio issues

Hi,

Even though I'm not quite experienced, I'd like to join the development of this rom. Right after installing it on my device and reading the logcat, I've partially fixed the audio problem. I've also created a pull request and given enough information on GitHub repository.

Edit: Full message from GitHub

These missing files which had to be under "/system/vendor/etc" folder lead to crashes on the apps which use sound. By placing them to where they have to be, crashes on music player when trying to play any music and video recording are fixed. Although there has been no sound yet, these changes are required in order to prevent crashes.

Also, there may be another way in order to fix crashes instead of doing these changes. It is to edit the paths to "/system/etc/" as the files are already placed there.

I guess the lines for "/system/etc" can be removed as well but I am not sure if there are any system part that uses this directory. It's better to let them stay under "/system/etc" as well.

Additional message:

These changes also fixed handset and earphones. The handset is working on calls and earphones work on video/music now. However, the speaker still doesn't work. Video recording works as well as the built-in microphone does.

Additional message 2:

From now on, neither audio nor screen recorder crash. Both work well.

Brilliant!!! Thanks Don't worry about not being experienced - this is my first proper project at getting a rom going, so I'm learning as well

New H815 build out (20180428) with fixed audio, camera and screen/audio recorder. This has given rise to the fact that BT calling is indeed broken like it is on AOSCP
H811 build coming out soon.
Massive thanks to @berkantkz, without whom I wouldn't have been able to do it

Edit: H811 build is up as well now
