[OFFICIAL][X82X][9.x][TREBLE] LineageOS 16.0 (pie) for LeEco Le Max 2

[ThE_MarD]

LineageOS 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. Linked below is a package that has come from another Android project that restores the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review.

Frequently Asked Questions

• I've been asked to provide logcat, how do I do that?
  You can either root and use an app like MatLog, or if boot logcat is required? You will need adb logcat from a PC. Here's a simple guide from the LineageOS Wiki https://wiki.lineageos.org/logcat.html
  
• My lockscreen crashes after reboot, what should I do to fix it?
  https://forum.xda-developers.com/le-max-2/how-to/guide-to-fixing-x2-lockscreen-crash-t3918911
  
• I don't see an option for call recording, what's going on?
  Only the stock dialer app supports it. If you install a Gapps package that overwrites the stock dialer app? It won't have call recording as well. Only the included dialer app of LineageOS is compatible to call recording since it needs to be a ROM implementation and I haven't seen a Play store app that adds support for custom ROM call recording. Please also note that call recording is blocked for countries and carriers that have laws against any form of call recording.
  
• What is Power-off Alarm?
  This feature allows you to set an alarm clock with the stock clock app included with LineageOS and then turn off the phone, and it will boot up a minute before the designated alarm time and then properly alarm. It works with the device either powered off and also offline charging.
  Using a clock app from OpenGapps Stock or from the Play store is not compatible to custom ROM implementations of power-off alarm... So consider this your heads up if you didn't know that already... As I am not responsible for anyone being late for their wedding/work/school/vacation if you tried a non-stock clock app with your LeEco msm8996 device powered off. :silly:
  
• What apps are recommended with the Open Source ConsumerIR?
  (WIP! I try to include it only on unofficial builds until selinux neverallow policy compatibility is fixed... Which tbh is beyond my current skill)
  Zaza Remote and Mi Remote work great. Smart Remote for Sharp TV also works. I'd recommend avoiding Peel Universal Smart Remote as it hijacks the lockscreen with ads...
  
• Pls sir, I can't connect to my network or IMS/VoLTE doesn't work! What can I try?
  Please look below at the "APNS Update from Google" section and try that. I can't offer much else for help sorry as I have zero experience with IMS/VoLTE as Canada blacklists BYOD from that feature... Otherwise if you need extra help? Hopefully someone else in the x2 community can give you advice.
  
• What is the difference between the official LineageOS builds and unofficial?
  Unofficial test builds are builds I put out to test changes before I push them to the Official builds... So please stick with Official builds if you want to play it safe... But if you wish to help test and provide feedback on changes before they go official? Unofficial test builds are the best way to do so.
  
• Where is the QuickCharge toggle?
  Settings > System > Advanced > LeEco Settings
  
• The rear facing camera won't focus, what should I try?
  Please go into Settings > System > Advanced > LeEco Settings, and then enable the focus fix. You may need to restart any open camera app or potentially reboot the system in order for the focus fix values to work.... If that doesn't resolve it? Please try EUI ROM... If it still won't focus? I'm sorry, but your hardware camera actuator is defective and you either need to try the Le Max 2 rear camera magnet trick (please Google it) or replace the rear camera hardware.
  
• Why is our widevine level only L3?
  Unfortunately Widevine L1 failed to work correctly on X2 and zl1/0... It would report we have L1 hardware support but vp9.secure and avc.secure codecs were failing to render, thus apps that used L1 like Amazon Prime would error out and revert to L3 and worst case scenario apps like Vudu would crash.
  I haven't seen any fixes for those codec issues, so I gave up on it as L3 works fine.
  Also, Netflix HD will never work on LeEco devices as they never got them "Netflix certified" which sounds like a money-grab move since L1 is all they should need. For example, Asus Zenfone 5z is L1 certified but not "Netflix certified" just like us and they don't get the option to stream in HD.
  This explains it a lot better
  https://androidpcreview.com/netflix-hd-android-tv-box/
  
• My device doesn't show any apps in the Play Store what should I do?
  https://lineageos.org/Google-Play-Certification/
  
• exfat does not work on LineageOS, what is up with that?
  LeEco Le Max 2 does not ship with exfat licensing so we are not allowed to incorporate it in LineageOS Le Max 2 builds. This was tested by both CrisBalGreece and I. If by chance there is an OFFICIAL EUI ROM build that includes exfat? Please let me know so I can test it as well... Here is the LineageOS device charter requirements on exfat
  https://github.com/LineageOS/charter/blob/master/device-support-requirements.md#exfat-support

KNOWN BUGS for x2 and max_plus

• Updating using the built in LineageOS updater when encrypted causes Google Play Services to crash repeatedly (updating works fine if you have Lineage Recovery installed though. Manually installing newer builds of LineageOS via TWRP also works.)
• Microphone and button on 3.5mm headsets using the 3.5mm to Type-C adaptor only works with reversed orientation (IE, official LeEco adaptor with the logo facing downwards)
• Dual-role USB does not work (our Type-C port can't detect if it should offer the option to host data transfer, charge the other device, or charge while using Aux out).
• Taking a photo during 4K UHD video recording produces a photo with green static instead of a photo. This bug only happens in Snap camera... Google Camera Mod and Open Camera (with Camera API v2 enabled) produces pictures without issue.
• Screen on Time is usually only around four to five hours (VERY hard to diagnose battery drain issues... Any logcat with references to battery drain or kernel wakelocks will help resolve this)
• CDLA cell calling has crackling/popping sounds
• Infinity focus not working (for panoramas, AR and some QR code scanners. Infinity focus also doesn't work in EUI ROM hmm... oddly enough some imx230_lg modules infinity focus can work if you dont need focus fix... so I blame LeEco for the messed up camera haxxs they did since s2 and zl1 have the same issues.)

KNOWN BUGS for max_plus

• ES9018 Hi-Fi Audio DAC for 3.5mm headsets to Type-C adaptors does not work (this is the bug that is preventing official unified builds of LineageOS of x2 and max_plus...)
• Fingerprint does not work when device is asleep (this is due to the ancient device firmware on max_plus being officially stuck on 13s... there is a pseudo 466d modem firmware fix attempt I made but have not received feedback on yet)
• Boot animation does not work (this is due to a fix for screen tearing... maybe one day I'll figure out a fix for boot animation to work with the screen tearing fix)
• When launching a camera app, viewfinder goes green for a second and then works normally
• After using USB port with Type-C headset or OTG with a flash drive, the device cannot charge until a reboot is performed (known bug even on EUI ROM)

APNs Update from Google
Latest update: 05-06-2019 (May 6, 2019)

This is an optional update if the current APN settings from LineageOS might not be up to date for your carrier and you need newer ones. This is the official APNs list from Google.

After flashing it? Please reboot to system and then go into Settings > Network & Internet > Mobile Internet > Advanced > Access Point Names > "..." menu button > reset to default.

https://sourceforge.net/projects/lineageos-for-x2/files/Mods and Tweaks/APNs Update from Google/

The official Google source git for this file can be found here:
https://android.googlesource.com/device/sample/+/refs/heads/master/etc/apns-full-conf.xml

Please note! This APNs list WILL get overwritten by the ROM on any ROM update and will need to be reinstalled.

@shivatejapeddi for his contributions to x2 such as finding the fix for QS Torch and the regularly requested VoLTE support XD
@KuranKaname for his contributions to x2 such as helping get Dalvik VM and HWUI sorted out when 14.1 settings didn't work on 15.1, plus his never-ending mission to finding the most optimized code.
@Tortel1210 for his contributions to x2 and helping out with gerrit.
@andr68rus for everything he has contributed to x2. He may have moved to the Xiaomi Mi Mix 2 (sexy device!) but will be fondly remembered for everything he did for the x2 to make Nougat great. We will finish what you started.
@GalaticStryder for his fix for truly display panel that is better than my fix and his other awesome kernel improvements.
[MENTION]ViSi0Naryy[/MENTION] for his contributions to LeEco msm9996-common with testing and contributions with Gerrit
@jabashque for helping fine-tune performance for LeEco msm8996-common devices! LeEco has never been so smooth!
@Lucchetto00 for converting Tortel's devicesettings into LeEco settings and adding QC toggle, plus his method of detecting if a setting exists and whether to display it or not.
cristiansilaghi (no idea if he has XDA as he communicates with me on Telegram) for helping diagnose the battery percentage issues and finding some extra commits to help make it as accurate as possible and an selinux fix for offline charging animation.

...and finally the community. This is for the community, by the community. Give yourselves a pat on the back.

If I missed anyone? Please let me know and I can add them.

Donations
@popeye13 for helping cover my replacement motherboard costs

Please donate to anyone mentioned above. Note that I do NOT accept donations (only exception to that was to help cover my replacement motherboard costs). I do alright with my full-time job and am financially stable for my family and I do this as a hobby, and receiving donations for my hobby would feel like I'm pressured to deliver more than I can with my limited spare time.

Thanks dude, it was a much awaited built, currently downloading

 

[ThE_MarD]

Heyyo, so for the lineage-16.0-20181005-UNOFFICIAL-x2 build? Noteworthy changes:

• Kernel is rebased on CAF Pie and has reworked Quick Charge code (no more QC bugs) and audio (no more Type-C to 3.5mm headphones orientation bug) from @GalaticStryder and his awesome kernel (we don't have a lot of optimizations on top as we are keeping our kernel as simple as possible, so if you want a fine-tuned kernel? I'd recommend checking out GS's thread)
• Audio is kanged from gemini (Xiaomi Mi5) and brings with it a lot of changes which should improve audio quality a little
• Autofocus fix will now be a build.prop implementation. Just need to use the focus fix zips in TWRP for an automatic method, or edit /vendor/build.prop and change/add persist.camera.focus_fix=1 (this change will hopefully be coming to 15.1 as well as I cherry-picked it for Oreo as well)
• msm_irqbalance to help with the smoothness of the ROM (Google recommends it and even uses it on the Pixel as noted in their
  Identifying Jitter-Related Jank article.
• thermal-engine config from pure marlin (we have had too many complaints about heat, so we will be dropping from the current thermal-engine.conf which allowed the CPU to go up to 79°c at around 75% CPU clock speeds, but now with pure marlin it will cap out around 72°c at 50% clock speeds)
• CNE, DPM and GPS are rebased on pie blobs (unfortunately, IMS, RIL and QMI are not as we haven't found a pie device with CAP pie blobs that have a compatible modem x12 device stack for us... we may be stuck waiting on OnePlus3 or Mi5 or Zuk2 because Google reworked how IMS/VoLTE works on Pie and that is causing issues for us...)

[pinhead231]

Testing rom now. Ok for daily driver so far. High cpu usage apps may cause heat though so can just avoid using those for now. Thanks for all your hard work!

 

[sssyraj]

There isn't mirroring to TV listed in the known bugs. Is it working in this ROM ?

Thanks.

 

[kksatpathy]

Great

 

[mjoach]

Awesome, can't wait to try it! Thanks to Marc and everyone who worked on it and even more so for providing details on what and how has been done, much appreciated!

 

[pinhead231]

Network traffic monitor, clock position and showing am/pm do not work.

 

[prajjwal.laad]

Guys please don't complain about rom sided features because many of them don't work. Mention only the device sided bigs for now.

 

[xlcashlx]

The VoLTE fix worked on first install.

After reboot I don't get the message to select preferred sim as I did on the first install, and VoLTE isn't working. Is there a way to trigger this manually? I tried playing around with the apns and had no luck.

EDIT:
Manually editing /data/system/users/0/settings_global.xml as per gerrit fixes VoLTE, but system behaves poorly. Mine was value=2 so SED wasn't working.

Will this cover both possibilities?

if [ -f /data/system/users/0/settings_global.xml ]; then
    sed -i 's/"multi_sim_data_call" value="1"/"multi_sim_data_call" value="-1"/g' /data/system/users/0/settings_global.xml
    sed -i 's/"multi_sim_data_call" value="2"/"multi_sim_data_call" value="-1"/g' /data/system/users/0/settings_global.xml
    restorecon /data/system/users/0/settings_global.xml

Thanks for quoting the complete OP. Loved scrolling through that again :good:

 

[kenciroz]

Hi, after flashing this rom I can't restore any other, older, backup. I tried with many differents backups (lineage, arrowos, revengeos) but I didn't succeded, and after restoring the backup, the phone goes on bootloop.

I have installed the new, unofficial, twrp, but the problem was already present before.

Someone have some idea of what could be the cause?

thanks

you have to use no treble recovery 3.2..1 format everything eccept internal storage, and restore the backup, should work...of course if the backup it's not treble..

 

[kenciroz]

I just solved the problem. The backup that I wanted to restore was a trebleized one. So I restored the backup, than I re-trebleized the partitions from twrp, wiped cache and delvik and reflashed the rom.


Before returning to lineage os I want to recover some important data from my previous backup

Anyway thank you.. ciao guagliò

 

[Beackman]

Another great job.

 

[ThE_MarD]

There isn't mirroring to TV listed in the known bugs. Is it working in this ROM ?

Thanks.

Heyyo, tbh I haven't tested it so it is unknown if it works or not... I can't test it as I have a "dumb" TV so.... if anyone wants to test and report? That would be nice heh.

The VoLTE fix worked on first install.

After reboot I don't get the message to select preferred sim as I did on the first install, and VoLTE isn't working. Is there a way to trigger this manually? I tried playing around with the apns and had no luck.

EDIT:
Manually editing /data/system/users/0/settings_global.xml as per gerrit fixes VoLTE, but system behaves poorly. Mine was value=2 so SED wasn't working.

Will this cover both possibilities?

if [ -f /data/system/users/0/settings_global.xml ]; then
    sed -i 's/"multi_sim_data_call" value="1"/"multi_sim_data_call" value="-1"/g' /data/system/users/0/settings_global.xml
    sed -i 's/"multi_sim_data_call" value="2"/"multi_sim_data_call" value="-1"/g' /data/system/users/0/settings_global.xml
    restorecon /data/system/users/0/settings_global.xml
fi

I got the script overhauled after you mentioned it, thanks! Meow the script will look if it's not set properly to -1 and will replace the value no matter what it is :good:
