[DISCONTINUED][ZS620KL] LineageOS 18.1 (Android 11) for the Asus Zenfone 5z

[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.

Features over Stock
FM Radio, File-Based Encryption (which allows power-off Alarm to actually work and no annoying PIN prompt half-ways through boot), QTI Bluetooth stack

KNOWN BUGS

• ViLTE does not work
• 4K UHD Video recording does not work in LineageOS Snap Camera app. (A workaround is to use other camera apps like OpenCamera or Gcam Mods)
• Touch sometimes doesn't work in Lineage Recovery. The workaround is to use the volume buttons to move around the menu and power to select or to reboot to recovery.
• SafetyNet does not pass (Unfortunately, this is not possible as your SoC has hardware attestation... the workaround is to use unsupported mods like Magisk which tbh I haven't tried myself as I don't root my devices, but other users said that plus the SafetyNet Magisk mod works)

Frequently Asked Questions

• Is there a different way to unlock the bootloader than the Asus official method? You can try the unofficial bootloader unlock here

Heyyo, LineageOS 18.1 for Z01R public beta test build is up! lineage-18.1-20210411-UNOFFICIAL-Z01R has QTI Bluetooth! NFC! WiFi Display! WiFi Hostspot! Source-built Vendor! Selinux Enforcing! File-Based Encryption! It's all working good.

 

[Spassbremse]

Hi There,
nice to read we'll get 18.1 on our device !

Is this beta okay to use on my only daily driver phone ? or should i better wait ?
& Which vendor-patch-level is it ?

 

[ThE_MarD]

Heyyo @Spassbremse from my tests so far she's very stable and I plan to daily drive it for a few days just to be safe. I went through the logcat and already fixed a lot of things just to ensure she's stable. There are a few more minor upgrades I'd want to do later on, but I'm super happy with the result that we currently have.

Tbh vendor patch level is just a suggestion lol... there's no way to check if someone lied or not about it. Technically the vendor security patch level should be based on the device's firmware and the vendor blobs. Ours is based upon stock ROM UL-Z01R-WW-100.10.107.123-user so I set our vendor security patch level to 2021-01-05.

I've seen other people set theirs to whatever date is on for just a few blobs kanged from a different device, but that's technically lying as the device firmware and other parts of the blobs would still be an earlier date... so what I'm saying is? Don't trust vendor security patch level. The most important part anyways is the system security patch level and selinux enforcing and avoid keeping root (like Magisk) on your device as root is a security bypass. I've seen vulnerabilities in the past to gatekeeper and keymaster that could allow an attacker to bypass lockscreen security that could only be achieved if the attacker had access to root... so yeah, I never install Magisk on my Z01R.

 

[ThE_MarD]

Heyyo, another new test build is going up! lineage-18.1-20210412-UNOFFICIAL-Z01R contains updates from Nokia 8.1 Android 11 release for GPS, IMS, QMI and RIL. Maybe it's just me, but LTE+ seems to be working better.

I haven't had time yet to check into if it's possible to force ViLTE support though

 

[ThE_MarD]

Well I haven't heard any serious bugs from LOS 18.1 so I'm going to be requesting official builds for Z01R and hopefully it doesn't take too long

 

[Dragonkind]

Excuse me, is call recording enabled on LineageOS 18.1 now? It's one of the attractive but rare function from the stock firmware.

 

[ThE_MarD]

Heyyo @Dragonkind , yes call recording was enabled on Z01R for LineageOS since the prebuilt vendor 17.1 days and is still enabled

 

[aLLyC]

Well done, the phone deserves this. Asus is still insisting on 2 versions android support policy, but thanks to you, hope find more contribution for the project for the bugs.

 

[ThE_MarD]

Heyyo @aLLyC , thank you for the kind words! I definitely love my Asus Zenfone 5z and our LineageOS 18.1 builds for her are already in better shape than 17.1! Only a matter of time before those official builds will be a thing

One the Hudson promote Z01R to 18.1 gets merged? Our next build will be 18.1 w00t!

https://review.lineageos.org/c/LineageOS/hudson/+/308513

 

[aLLyC]

Do you think that this version supports ethernet tethering ? I am using USB-C Ethernet Adapter, however Zen failed to work with directly routers wan port while sammy gets it is done with Android11.

 

[ThE_MarD]

Heyyo, w00t! We were approved! Our next official build for LineageOS will be for 18.1! Meow I only have my Lenovo Z6 Pro left to get official builds hehe

@aLLyC , I'll ask Kailash as he's the Z01R kernel guy as tbh I'm unsure what changes we would need in the kernel to support USB devices (afaik it's the kernel only that needs the adjustments???)

 

[aLLyC]

Great!! normally it supports ethernet connects an node but not tethering... thanks!
Sammy UI has a seperate option for the feature under tethering menu in note series in Android 11

 

[aLLyC]

Details below;

 

[ThE_MarD]

So I forgot to post an update lol oops, but LineageOS 18.1 for Z01R build from 04/20 is posted and contains stuff like the LiveDisplay color profiles for those who want to try it before the official build goes up in two days https://osdn.net/projects/lineageos-for-z01r/releases/75006

 

[nnmanobala]

Thank you for your development effort towards Zenfone 5Z. I'm interested in installing your ROM as it has encryption enabled.

Does this support copying text from recents(Pixel feature drop)?

Also does it support VoWiFi on Jio(Indian carrier) that was given to stock Zen UI in its penultimate update? I'm on Evo11 (OSS vendor) and it has VoWiFi support for the aforementioned carrier.

Thanks again.

--- Edit ---
VoWiFi works on Jio without problems.

 

[ThE_MarD]

Heyyo @nnmanobala thanks man! Yeah encryption is important to me, so I made sure we support File-Based Encryption as AOSP has depreciated Full-Disk Encryption that our stock ROM used.

Tbh I'm unsure for that feature as I think it requires the launcher support it... So maybe those who use Pixel Launcher could answer this question?

For VoWiFi? I can't test that as I'm in Canada where they block VoLTE, ViLTE and VoWiFi on BYOD as they consider those "premium features... So no idea tbh if it works. Do you know if by chance it worked or not on LineageOS 17.1?

 

[ThE_MarD]

Heyyo, I just realized that the first official build of LineageOS 18.1 is up for Z01R! w00t! Thread updated

 

[tooth fairy]
