Same problem here (with gapps and Magisk). I updated also my LOS 16 to 17.1 and the MAC changes at every reboot. But i have another device which was newly installed from scratch which doesn't have that problem. The MAC keeps the same. May be some kind of update problem?

I have done some tests. It looks like expected. If i update from LOS 16 to 17.1 the MAC always changes. If i wipe /data before the MAC keeps the same. But with wiping data an update makes no sense.... So something on data results in that problem, but i don't know what. Any ideas?

Solution found. I removed the folder /data/vendor (after backup) within twrp. While rebooting this folder is automatically recreated. Now the MAC keeps the same.

So ... how to install LOS updates? It made a note that an update is avaiable. I download it (around 480MB), select install and it informs me it will reboot into Recovery to install it. So it reboots, does some stuff and then i'm, in TWRP ... and now what? What does it expect me to do? Reboot to system just brings me back to TWRP. Fo i have to do a Factory Reset?

Sorry if these questions are stupid, but it really isn't straight forward for some people (stupid ones like me).

And now the Google Apps are gone :-/

It should boot to TWRP, automatically flash update zip and boot to system, all without any user input. If it didn't, then you most probably have wrong twrp flashed. Please flash the one in the first post and try again. This updater process is just automated dirty flashing of downloaded zip, so gapps and data won't be removed.

But i did: I have TWRP 3.3.1-0 from the link in this sentence: "If you prefer TWRP over Lineage recovery, you can get it here."

Then maybe you have initially flashed the zip incorrectly (didn't fully wipe partitions and/or didn't format them before flashing)? I don't really know what could be the issue here other than the things I already mentioned. Last possible but very unlikely couse of the problem could be corrupted zip after downloading or this particular build is just faulty, after merging some changes done to lineage's sources. To confirm or bust this hypothesis you would need to start over from flashing twrp from first post, wipe all partitions and format them accordingly, flash last working for you los, and then install update through updater in setting app. If it fails again and you stay in twrp, please copy the twrp logs, so I (if the problem is some step you overlooked) or most likely @NeoArian (if it is broken build) can help you.

Hi all
I'm currently on the concept software I think is MM 6.0
Im trying to figure out if switching to this new OS worth the effort or not.
I'm looking for a reliable and fast os, actually mine is getting slower, probably because of the three years without a factory reset.
I really need an advice, I'm still using my z3c as main smartphone because of his compact dimensions and I'm trying to give him a second chance with this os.

Hi Everybody,

Big problems of sound in the last build flashed today (lineage-17.1-20201013-nightly-z3c-signed.zip). No notification, no music, no ringing. No sound too when I plugged an earphone.

When a call comes in, micro is on mute and unable to unmute. Not possible to hear the caller too.

Seems to be related with the last build because I flashed the 3 october build again. With this build I have sound (but phone is not usable unfortunately).

Is there anyone else in the same situation ?

Same here. I don't really use the z3c as a daily driver, but I don't remember this issue in previous builds.

Unable to unlock phone

Interesting. Can you tell me what you did exactly? I flashed 0610 with twrp too but after reboot I couldn't unlock my phone...

Hello,
I have the same problems like tomKater. After flashing to 1310 build there where sound issues (no sound at all during phone call and playing music etc.). After flashing back to 0610 with TWRP and wiping cache/dalvik I was able to unlock my phone with SIM-Pin but not with number-based unlock code. Screen went black after correct PIN-input and shows the Dial-Pad again. Any Ideas to break this unlock-Pin loop?! Nevertheless this is a great ROM - thanks to NeoArian.

May be thats the difference. I use only sim code, no additional screen lock. This worked with 0610 after rollback.

Sound problem after flashing the 10th October build

Exactly the same problem of sound for me after flashing the 10th October build.
Any idea of what we can do to ? Just come back to the 3rd October build ?
Thank you for you help :)

I´ve updated again to 1310 build from 0610 build. Afterwards unlocking with unlock-code works again but the sound issues occured again. Trying to remove unlock screen-code and than flash back to 0610.

I tried too this steps :

- Flash in 1310 build
- disable lock screen
- Flash in 0610

=> still doesn't work. I swipe to unlock the phone and black screen. So at this moment I'm back in 1310 build and use a bluetooth headset for calls (this is the only way to communicate). I hope that there will be a fix very soon because it's my daily driver ...

Same behaviour with disabled lock-screen after downgrad like tomKater described in his post. But also bluetooth headset is not working in 1310 build after reflash.

    Thanks to everyone for the really detailed testing :) I really appreciate it.
    Since yesterday (still on 18.1), I have two kernel wakelocks preventing deep sleep:
    - msm_serial_hs_dma
    - BTLowPower

    I used BBS with the adb shell settings put global hidden_api_policy 1 fix to check the wakelocks.
    Regarding the BTLowPower wakelock, @J_C_D has fixed that on lineage-17.1 recently and at this time the lineage-18.1 branch was already forked. I will make sure to include the fix for lineage-18.1 with the next update.

    Good Evening!

    It's the time again, you might have already noticed that lineage 18.1 is official for some devices now. We, the sony shinano maintainers, were not sleeping and have also prepared our device for 18.1. I have uploaded a test build here: https://sourceforge.net/projects/ep...18.1/lineage-18.1-20210406-UNOFFICIAL-z3c.zip
    I would appreciate some testing/feedback on this build. There shouldn't be major issues on the test build, from my own testing it should be on-par with 17.1.
    I am optimistic that we can also achieve an official release of 18.1 for the z3c.

    All source codes can be found on the lineageos github in lineage-18.1 branches + additional patches for sony msm8974 are up on gerrit: https://review.lineageos.org/q/status:open+-is:wip

    Happy flashing!

    Thank you NeoArian and all other developers!
    Your LineageOS 17.1 build really revived this small phone!
    My previous experiences with installing unofficial builds were not as great as this one.
    The only things I miss compared to stock Android 6 are the camera button full press to open the camera app (which by the way starts slower than on stock Android 6), the secondary mic noise suppression (which wasn't working anymore on mine anyway) and the service tests opened with the *#*#SERVICE#*#* code.

    About this new LineageOS 18.1 (I used MindTheGapps-11.0.0-arm-20210412_124103), I didn't notice any problem compared to 17.1.
    In fact, using Migrate to restore all apps and settings, I almost thought the update didn't work since it booted like usual.

    For the other users, in addition to Migrate, I of course reinstalled Magisk, which doesn't work natively (even with the workaround of installing 20.4 first) on this new 18.1 build. The boot_patch.sh file has to be modified, I've attached a version of Magisk 22.1 with that file already modified (works at least on Z3C). NeoArian: is there any way to modify the builds so that they use init instead of init.real?

    I did some basic testing
    Pretty extensive "basic testing"!

    • phone calls are working, but I believe that microphones are swapped, using the upper one as main, resulting in a low volume during calls
    • mobile data is stuck at EDGE for me, I couldn't get it to use LTE instead
    • double tap to wake and other classic gestures are fine
    • unfortunately I cannot test GPS or NFC neither
    - Phone calls were fine on 17.1, haven't checked yet on 18.1. UPDATE: still fine on 18.1
    - LTE works here (at least band 1). I'll see if I can connect to different bands.
    I don't know if it helps, but here's what modemcaps says:

    - Double tap to wake didn't work for me on stock Android 6 (at least when on deep sleep). It seems to work now which is an improvement.
    - GPS works fine.

    I'm using it from now on, so I'll report any problem.

    First thank you NeoArian and all other developers involved for your great work! I also did some short tests and found nothing which was not working. I worked with OpenGapps test build of 20210130. I tested:

    - WLAN
    - Bluethooth
    - Mobil date
    - phone call
    - Camera/Video/flash light
    - Audio and video playback
    - normal usage like my los 17.1 daily driver

    I used some configuration like i did on my los 17.1 daily driver and it looks really good! Unfortunately I cannot test GPS as my test device had an hardware problem here.

    So really fine from my side here, only the test with Magisk to root the device didn't work. But this shouldn't be related to los 18.1. Hopefully Magisk will be functional sometimes later.

    Thanks again!

    Hello, I installed 18.1 yesterday (oh boy, it was hard and expensive - SIM Lock with 0 attempts) and I'm impressed. I didn't installed GApps as I can't found ARM pack (anyone help me plz 😁). I skipped LOS17.1 so I compare it to stock 6.0 and in my opinion it's noticably faster and battery lasts longer however maybe because I have no GApps.

    Tested so far
    - WiFi
    - Mobile data
    - Phone calls (calling and answering)
    - Bluetooth (sending/receiving files, earphones, Xbox gamepad, keyboard)
    - GPS (not so advanced tests, I'll test it later)
    - Camera (photos, video in front and rear cams, flashlight)
    - OTG (pendrives and mouse)
    - Screenshots
    - Receiving SMS, but not sending (inactive number)
    - Charging using microUSB and magnetic connector

    Not tested yet:
    - Hotspot
    - NFC
    - Screen recording
    - Screen mirroring

    Found some visual bugs but not sure if it's LOS or Nova Launcher in beta channel so I'll check it and give info later.

    I'm waiting for future builds for tests and hope they'll be [OFFICIAL]!

    Hello @NeoArian , hello community. I'am very happy to see that the "BTLowPower" wakelock issue was fixed by @J_C_D and that it was merged into the android_kernel_sony_msm8974 repository last week. Thanks to all of you that spend your time supporting the Z3C and other older devices until now.
    5
    Yes, that's right.
    When Safe Start is turned on, the accelerometer does not work. Therefore, screen rotation, light sensor does not work.
    Thanks for the report. We were able to reproduce it and have fixed it. We will merge the fix within some days so that it will be fixed in the upcoming releases.
    Greetings, arian.

    GOOD NEWS EVERYBODY!!!
    I managed to finally fix the persistent "BTLowPower" wakelock
    which caused the CPU to no longer enter Deep Sleep state and thus resulted in high battery drain once Bluetooth had been enabled! 🍻

    UPDATE: I just found a much simpler solution that does the trick! The real culprit was a #ifdef in BT Power Management that was introduced by a commit in July 2019 and then has fallen into oblivion :ROFLMAO:.
    Fixed! -> Version 3.
    @tblr0ne , @L.Lmar : can you please also test this version?



    *** TESTERS NEEDED! ***

    Find attached the modified boot.img. USE AT OWN RISK!

    Installation:
    - reboot Z3C into Bootloader (Vol+)
    - flash new boot image over current LineageOS17.1 installation using fastboot
    Code:
    fastboot flash boot boot-BTLowPower-fix-3.img
    - reboot
    Code:
    fastboot reboot

    NOTE for Magisk users:

    After flashing the new boot image, it is required to re-install Magisk. Do this by immediately booting into TWRP after the new boot image is flashed.
    Also note that you need Magisk v20.4 for this! Later versions won't work.
    Anyway, you will be able to upgrade Magisk to up-to-date versions using Magisk Manager after the system has booted.

    @NeoArian when everything seems ok, I will create a merge request in LineageOS/android_kernel_sony_msm8974. Is this the correct place / way to go?
