LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.

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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Base source code is available in the LineageOS Github repo.

GPL compliance:
Device tree source code: https://github.com/YaAlex3/android_device_asus_qcom_common
Kernel source code: https://github.com/YaAlex3/android_kernel_gunmetal

Working:
Camera (and flashlight)
WiFi
Bluetooth
Telephony (Calls and Data)
Audio (Record and Playback)
Video Playback
Sensors
GPS
VoLTE

Not working:
So far everything works.

Compatibility:
Compatible with all variants of Asus ZenFone Max ZC550KL
Builds are based off the Xiaomi's Android 9 firmware with proprietary blobs.

Downloads:
Unofficial builds (OTA supported)

Notice:
No custom kernels are supported in this thread. Only stock kernel and official builds will be supported. No bug reports if that's not the case.

Installation:
Reboot to recovery (TWRP recovery for Mi 8)
Format /system, /data and /cache
Install Marshmallow based firmware.
Install LineageOS zip package
Install [optional] a Google Apps package of your choice (Open GApps is advisable, but stock and super variants are not recommended!!!)

Important notes:
* Required * firmware version must be MARSHMALLOW
GApps can only be flashed on clean installs.
Magisk can only be flashed after first boot

Do you really mean this requires installation of TWRP recovery for Xiaomi Mi 8 on the Asus Zenfone Max (ZC550KL)?

Please would you kindly provide the link of the version of TWRP recovery for Xiaomi Mi 8 which also works for Asus Zenfone Max (ZC550KL)?

VoLTE is not working.

Please tell how to enable it. I have enabled the LTE option in Mobile Networks. Data works fine in LTE mode but not voice. How to get that working? I use Jio in India.

I installed with TWRP recovery 3.3.1-0 for Asus ZenFone Max by YaAlex after flashing service official firmware WW_ZC550KL_V13.8.26.92 (Marshmallow). The first problem I found is that the unit cannot be powered off normally. After long press of power button and selected "Power off", the phone shut down but restarted automatically after about 10 seconds. I wonder if anyone also face this problem.

Same here also

I also noticed the same but for me this not a serious issue. It is benefit only that phone would always stay ON. My issue is with VoLTE. How to solve that?

It seems to me that USB connection (connect to PC and also OTG) does not work. Magisk can be installed successfully but magisk manager does not detect root access request from Apps. Would anyone please kindly help to verify these?

No ROM seems to work

Hi there,

I tried to install this ROM (and 4 or 5 others) and no one works after a dozen hours of work. The model is a Z010DD written on the battery, but ASUS confirmed me that the ZC550KL is the commercial denomination, so it's the same thing.
When I installed TWRP 3.1.1 on the Zenfone Max, TWRP couldn't mount the filesystem: it asks a password. I tried default_password, doesn't work.
I couldn't even restart in normal mode, I had a black screen, and when I connected the USB cable, I had a lot of popup on the Explorer Windows saying that the local disk has a problem (local disk H: I: J: K: L: etc...)
When I saw that, I thought I had no choice than wipe the phone like a factory reset (with no Backup :( ) in TWRP, and then install the ROM.

But I had a black screen after reboot.
I tried the CleanMax ROM (it works until it asks a WIFI connection which doesn't find any WIFI and I can't go further), the Resurrection Remix ROM (black screen), the LineageOS 15 ROM (black screen), the ASUS official firmware (black screen), nothing works.

I did an advanced wipe by wiping all filesystems and tried again: same problems.

So I dug to find that I can repair the filesystem. Bingo, the system partition had a problem during the check. I repaired the other filesystem (data, cache), and the repair of the system partition was OK then.
I retried all the ROM installation -> same problems

I tried another thing: convert each filesystem to ext2, and then revert to ext4 and retry the ROM installations.
Same problems...

Does anyone have an idea to help me to make a ROM work on this device?

Hi guys.
I'm here after a lot of time using lollipop and mm stock ROM, after a custom oreo based rom, now I'm using clean max, mm based rom.
The problem for all mm rom, Is a bug I experienced using stock android 6,0 and clean max, when I've battery less then 40% and I try to shot a photo, my phone get shot down because marshmallow says my battery is at 0(from 40%). Not true. If a push power button to restart, still battery at 0, android can't start. If I put battery on charging , battery is ok and say 40 % a real value , infact I can use my ZenFone for hours... I tried several pie based rom and I think this bug doesn't exist. But all of them has a bug with shutdown, every pie rom if I shutdown my ZenFone restart the phone, so I'm unable to shutdown. All others things are ok. No visible bugs a part the shutdown one . Question, does exist a custom pie or oreo ROM , without visible bug? In meantime I tried to come back to lollipop stock(without battery percentage problem).. But I've an error at recovery and I'm forced to use clean max or other custom ROM 6.0 based with that strange battery bug. Thanks for your attention.

Edit

Solved using last lineage.
Definitive rom
Perfect!

Hey y'all, first time poster here so my apologies if this is a dumb question.

Any word on whether this ROM is compatible with the ZB555KL model? I've got a spare one of these sitting around, so I'll take my usual approach of "press the button and see what happens" unless the answer is "definitely not."
