[DISCONTINUED][X82X][8.1.X][TREBLE] LineageOS 15.1(Oreo) 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
  
• The rear facing camera won't focus, what should I try?
  Please go into Settings > System > Camera 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.
  
• 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.
  
• My device won't boot after installing one of the treble builds of LineageOS, what can I do?
  Dirty flashing any LineageOS build (especially treble) with mods is completely unsupported as I cannot guarantee root/xposed/audio mods are treble compatible or can transition from non-treble to treble. If you have any mods like this? Please backup everything important off of your device > download LineageOS and Gapps of choice on a PC or USB drive that works with Type-C (or an adaptor to type-c) > on the device reboot to TWRP > Wipe > "Format Data" button > type "yes" > tap check box on keyboard > reboot to recovery > wipe Dalvik, system and cache > copy LineageOS and Gapps to the device > install ROM and gapps at the same time > reboot to system... If that still doesn't work? Please provide logcat attached in this thread.
  
• I installed the latest version of an Oreo based ROM such as LineageOS 15.1 and now TWRP can't open my data partition! What happened?
  Quota support was enabled in LineageOS 15.1 for x2 for improved storage performance but it requires TWRP to also have it enabled. Please use latest official TWRP which includes quota support.
  
• 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
  
• Why does LineageOS 15.1 not have a QuickCharge toggle?
  QC3.0 does not negatively impact battery health as our battery supports the wattage QC3.0 is capable of doing. The only real negative impact on battery health is leaving a device charging to 100% all the time. As for those who don't want to use QC? They always have the option to use a non-QC charging block or to edit the /vendor/build.prop and disable persist.sys.le_fast_chrg_enable
  For more information regarding this, please watch this YouTube video on charging device batteries
  
• Switching between unofficial and official builds screws up my LineageOS install! How to fix this?
  Flash the migration tools linked in the first post before the ROM switch. If that does not work? Please do a data backup off of the device and then a full wipe (dalvik, system, cache, data) and then install the ROM and gapps. LineageOS official builds have strict build signing and does not officially support switching to and from unofficial builds.
  
• What are AKT profiles and how can they help the Le Max 2?
  Advanced Kernel Tweaks modify the way the kernel handles things and can either have profiles set up for battery life or performance or a better balance of both. I'd recommend looking into this post by @monleylord for more information on it
  https://forum.xda-developers.com/le...o-le-max-2-t3771577/post76694682#post76694682
  
• What are the recommended Google Camera Mod version and settings for Android Oreo?
  Whichever build of Toylan009 is out that isn't device-specific builds
  https://www.celsoazevedo.com/files/android/google-camera/dev-tolyan009/
  And here's recommended settings by @Manavbishnoi from Telegram
  

  (Read till the last)
  
  Best Gcam for our phone is by Tolyan0009
  
  Get the Tolyan0009 gcam latest link from @googlecameraport (also don't use the minimal settings version)
  
  Here are the best settings for gcam:
  *In advanced settings...
  
  
  [GENERAL]
  •Model= Pixel 2 XL
  •Config camera hdr+ = Auto OR Pixel 2017 Zsl Hdr+(new)
  •Hdr+ Parameters= Default(lowest)
  
  
  [Front camera]
  •Enable HDR+ for front camera = [turned On]
  •Increase the detail of hdr+ = [turned On]
  •Flip image from front camera= [turned Off]
  
  
  [Portrait mode]
  •Portrait mode on all models= [turned On]
  •HDR+ enhanced portrait mode= [turned Off]
  •Zoom in default Portrait mode Back camera= Turned off
  •Zoom in default portrait mode Front camera= Turned off
  •Save all portrait mode pictures to same folder= [Turned Off]
  
  
  [Other]
  •Enable smart burst= [Turned on]
  •Max sensitivity analog gain= Auto
  
  
  *In normal settings...
  •Hdr+ control= [Turned On]
  •Correction of auto-exposure= (See at the end of post)
  •Turn off noise reduction= [Turned Off]
  •Lens blur megapixels= 8
  
  ****RESTART GCAM FOR DEVELOPER SETTINGS TO APPEAR IN THE APP****
  
  *In developer settings...
  •Check -> camera.diet_burst
  •Uncheck -> camera.use_photos
  
  
  Now, Its best to have correction of auto exposure set to off. But if in case you are in dimly lit area, set correction of auto-exposure to 8x And use HDR+ enhanced enabled always with Correction of auto-exposure
  
  And never set hdr+ parameters to super high unless you are trying to take picture of extremely low lit scene. Also don't forget to set hdr+ parameters back to Default(lowest) when you're done with the low light photoshoot.
  
  
  And for video, Use footej camera unlocked
  
  You can ask @Manavbishnoi if you're having trouble with gcam cameraport

Known Bugs

• Sometimes on reboot the lock screen crashes. (VERY hard to diagnose and fix this qseecomd/keystore/keymaster issue... only temporary fix if this happens is to reboot to recovery and go into > advanced > file manager > /data/system/ > delete any locksettings file > reboot)
• 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
• Using a USB Type-C to 3.5mm adaptor for auxiliary cables or headphones sometimes only work if the Type-C connector is being used in only one orientation or requires being turned around. (Similar to LAOS 14.1)
• When starting video recording audio crackles for a second
• Infinity focus not working (for panoramas, AR and some QR code scanners. Infinity focus also doesn't work in EUI ROM hmm...)
• Some users report battery won't charge past 80% or 90% when using QC3.0
• Sometimes can't charge on QC3.0 if temperature of battery is above 40°c (some users report also report this issue below 40°c)
• Charging using a Type-C to Type-C does not detect properly, or only works when rebooted. Even so, sometimes requires replugging when device is off.
• can't customize the back button. Only recents and home button show up as customizable. (Unsure if this is a bug or if we aren't allowed to customize it?)
• Using Jello (stock LAOS browser) on some websites crash (such as web.de) but those sites work fine on Chrome and other browsers
• Protected Apps not implemented (LineageOS issue, not device)
• Status Bar customization not fully implemented (LineageOS issue, not device)

Special Thanks
@codeworkx for his major contributions to the LeEco msm8996-common code and kernel and the awesome open source camera HAL
@mosimchah for his contributions to the LeEco msm8996-common code and kernel
@moto999999 for helping the x2 get LAOS 15.1 working. When others left LAOS he helped get the momentum started again.
@infrag for his contributions to x2 such as the multiple audio fixes, LEDs and sorting out the open source camera HAL blobs and assisting with QS Torch
@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

...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
@Bollex for also helping cover my replacement motherboard costs
@kurtn for also also helping cover my replacement motherboard costs
@xlcashlx for also also also helping cover my replacement motherboard costs
@rbergiex (Robin Vd Berg since I'm unsure on username) for also also also also helping cover my replacement motherboard costs

(If I got your XDA forum usernames wrong please let me know)


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 my contributions are minor compared to theirs as I'm mainly good at testing and smaller fixes. They deserve the donations more than I.
