I'm coming from carbon rom 8.1.0, flashed this clean with gapps nano, but back camera is not working. Also from time to time the device freezes and no messages coming in anymore. Only a hardreset helps.
The version is the latest from november. Is it a buggy version or is it my only error?
Thanks for the help!

I have just tried to encrypt my device with a pin and it worked as expected.
Could you maybe try again or get some logs so that we can look further into it?
Also, as Serf95 told you, it's worth a try to flash the latest stock firmware again before trying it.

We are looking into the screen lock issue. Was the GPS behaviour better from builds which are older then a week? We have merged some GPS patches.

NeoArian I've bought second Z3C because I use first as daily driver without GAPPS. But apparently I need apps that requires GAPPS.
Second z3c I installed exactly same, exactly same issue: after encrypting indefinite LOS animation at boot.
Without GAPPS it works fine, but with GAPPS it's not working.
This time I used current versions: lineage-17.1-20201110-nightly-z3c-signed, lineage-17.1-20201110-recovery-z3c and open_gapps-arm-10.0-nano-20201111.

Any suggestions what logs (and how please any/tutorials links) could I get to shed some light on this issue?

I went also this road but I'm stuck another errors I can't resolve:
z3c:/ # tune2fs -l /dev/block/mmcblk0p25
tune2fs 1.43.3 (04-Sep-2016)
tune2fs: Bad magic number in super-block while trying to open /dev/block/mmcblk0p25
1|z3c:/ # e2fsck -f /dev/block/mmcblk0p25
e2fsck 1.43.3 (04-Sep-2016)
/dev/block/mmcblk0p25 is in use.
e2fsck: Cannot continue, aborting.

Thanks.

Hi everyone!
About back camera problem - from my experience if is not working, in order to fix it you have to flash latest firmware using Emma and then flash recovery + rom.

And going to the main point of this post - MMSes are not working.
I tested latest build of LOS 17.1 (lineage-17.1-20201110-nightly-z3c-signed.zip) to check if it will resolve the issue (it didn't).
I decided to do the whole procedure from the grounds up, to make sure MMSes aren't working not because of my fault.

- I flashed latest firmware using emma.
- I tried sending and receiving MMSes on stock MM (success).
- I flashed twrp-3.3.1-z3c-20200212.img recovery.
- I flashed just lineage-17.1-20201110-nightly-z3c-signed.zip, without magisk and without gapps.
- I booted to system, turned on mobile data and tried to send MMS (failed to do so).
- I tried to receive MMS (also failed to do so, I only get message, that there is MMS available for download but it can't be downloaded. I is downloading forever until it stops and says that the message can't be downloaded.)

At this point I was sure it isn't my fault. I checked APN settings and took screenshots of the configuration (didn't change anything, just took ss).

I remembered that MMSes had been working before, with custom ROM on my device. I checked older versions of LOS 17.1 but they have the same issue.
I have one of an old UNOFFICIAL 16.0 build from you @NeoArian, saved on my computer. I gave it a try.
- wiped system, data, cache
- flashed twrp recommended for LOS 16.0 - twrp-3.3.1-z3c-20200212.img
- flashed lineage-16.0-20190510-UNOFFICIAL-z3c.zip, without magisk and without gapps
- booted to system, turned on mobile data
- tried sending and receiving MMSes and ........... IT WORKED ON A FIRST TRY

I checked APN setting on LOS 16 to compare them with configuration from 17.1 and they were exactly the same.
Now I am sure that MMSes are broken on LOS 17.1. Could you @NeoArian give it a look?
They were working on your unofficial builds of LOS 16, so you may know or remember how to fix it :fingers-crossed:.

Thanks in advanced.

If I can help too : about the camera stock issue : I encountered this problem too when I flashed my Z3C from scratch (while previously I have used this build with no problem). I had to flash several times (and immediately testing the camera) before stock camera works again. No idea why.

Maybe this can help.

Ok, so I did more tests on latest LOS 17.1. What I discovered is that MMSes are working but only when mobile data is DISabled, which is super weird.
- just wifi enabled - receiving/sending MMSes works (at first time I tried it with just wifi, the notification came up, that asked to grant permission for downloading MMSes via wifi. I granted it and MMS was downloaded successfully).

-just mobile data enabled - receiving/sending MMSes doesn't work at all. It is sending/receiving them until error, just how I described it in previous post.

-mobile data and wifi is enabled - receiving/sending MMSes doesn't work at all. It seams that mobile data has higher priority, so even though that wifi is working, it tries to use mobile data and fails to do so and when it fails it doesn't fall back to wifi.

-mobile data and wifi is DISabled -receiving/sending MMSes works :silly:. It is extremely weird, since it wasn't working last time i tried it with this configuration. It may be that since last time I have tried, I have given default messaging app every possible permission, disabled battery optimization, enabled unlimited data usage of mobile data and wifi and in roaming etc. After that when I try to send or receive MMS and have wifi and mobile data disabled it works. While sending/receiving MMS I can see data transfer indicator in the middle of status bar. I think that the messaging app sees, that there is no internet and since I've gave it every possible permission, it uses mobile data to send/receive MMS, even thought it wasn't enabled by hand, by me. In this scenario, mobile data must be used for sending/receiving MMSes, because there is no other option for messaging app to fall back.

So here is my thesis describing the MMS bug:

When mobile data is enabled by hand by a user, messaging app can't send/receive MMSes, even thought the internet is available. When none internet is available, messaging app enables mobile data automatically, just to receive/send MMS and then it works (mobile data isn't "turned on", it doesn't show any sign of it being enabled in QS and status bar. I know it is used only from data transfer indicator, that shows for a few seconds while MMS is being sent/downloaded). It seams that the app mistakenly tries to enable mobile data automatically, even thought it is already enabled, so it fails and stops, so at this point it never reaches the part of actual sending/receiving MMS.

With this information it should be easier to fix the issue, because now we know, how the environment must be configured for it to fail.

I would like to know if it happens to anyone else on the latest LOS 17.1 - and if it happens - I would like to know if edge cases I described in this post, check out to your situation.

Cheers

Hi pawloland,

Same issue on my unit with this firmware.
But even with mobile data turned ON or OFF and Wifi turned ON or OFF, I have still no luck in sending or receiving MMS :(
I live in France and my provider is SFR (I have double checked APS configuration, it's OK)

During my tests, after enabling Wifi (while mobile data was disabled), I had a notification to tell me I have an incoming MMS and that I have to enable an option to receive MMS with mobile data disabled (see attachment). But MMS still cannot be downloaded :(

I'm currently trying to find the right configuration / combination to be able to send and receive MMS!

Any help would be appreciated.
@NeoArian: Thanks a lot for this firmware :good:

Hello,

I have done few more tests, and after restoring default APN, I can now receive and send MMS with WiFi ON or OFF and mobile data ON or OFF :)
So you are saying that you can have wifi turned off and mobile data turned on, at the same time and after that you can successfully receive and send MMSes - am I getting it right? I would be very glad if you could try this exact scenario for me just one more time, to make sure every possible scenario is working for you. If that's the case then good for you. I still can't receive MMSes while having mobile data turned on manually :(

Here are the last tests I have done (Airplane mode OFF, 4G/LTE):
- WIFI OFF / mobile data OFF : OK (sending and receiving)
- WIFI ON / mobile data OFF : OK (sending and receiving)
- WIFI OFF / mobile data ON : KO (sending and receiving) with 4G/LTE network at first time, BUT if I switch to 3G/H, it works! Could you please check by yourself with this test (1st attempt in 4G/LTE failed, then switch to 3G/H as "preferred network" and see what happen) ? try to"force stop" the SMS/MMS app before switching from 4G to 3G. Not sure if it still works after switching back to 4G (one of my attempt was OK, one other failed so I don't know what to think :confused:, I don't remember if I "forced stop" the SMS/MMS app before switching back to 4G)
- WIFI ON / mobile data ON : I don't know. Behaviour is really strange. Sometimes it works, sometimes it doesn't. I think it depends on what is the first network enabled (Wifi or Mobile data) after disabling "airplane mode".

Hope it helps.

Regards,

    Good evening.
    I'm sorry that I'm not really active here currently, I'm having much to do with university.
    I appreciate your detailed testing. Could you also try to use a different SMS app and set it as default in settings? I will test it myself too whenever I get some time for it.
    Greetings, arian.

    Hi, I tested this quickly without success. I tried 3G, it didn't help, so I went back to 4G, enabled wifi and mobile data. Then I disabled "Mobile data always active" in dev setting (I had it enabled in previous tests). After I disabled it, I could send and receive MMSes on wifi+mobile data or just mobile data, untill I've disabled wifi and mobile data. After reenabling mobile data, I again couldn't send nor receive MMSes. I think that this option in dev settings is causing problems with MMS that won't send nor receive using mobile data enabled by hand.

    If I can help too : about the camera stock issue : I encountered this problem too when I flashed my Z3C from scratch (while previously I have used this build with no problem). I had to flash several times (and immediately testing the camera) before stock camera works again. No idea why.

    Maybe this can help.

    Yesterday I was reading what the other folks of the Z3C Carbon ROM are discussing and found a solution, at least for mine back camera problem:

    You could try if the camera starts working after deleting the folder /data/credmgr with a root file explorer and then rebooting. By doing this, the credmgr folder with the credmanager files are rebuilt by the system, which can help fixing camera issues.

    Source: https://forum.xda-developers.com/showpost.php?p=81904527&postcount=14

    This worked for me the first time I tried. Some others in the Carbon ROM thread where not successful. As TomKater wrote, he had to flash several times to get the camera working, I suggest that when the camera does not work after deleting /data/credmgr to try it several times and to see if this makes a difference. Good luck!

    Hello,
    Camera wasn't working since the beginning and as advised, I have flashed the stock ROM and now camera is working again on LOS 17.1.
    Only my digitizer is broken (at the bottom) and I have to replace it.

    Hello! I am using the latest official version of LineageOS 17.1, and I noticed that the minimum screen brightness is much higher than the minimum brightness on the stock firmware. What could this be related to and will it be fixed? The same problem was on LineageOS 16 (also official builds)

    I also noticed that the Assertive Display function, which worked on the stock firmware, does not work on LineageOS 17.1. Regarding brightness, I noticed that the firmware only has 255 brightness levels, while the stock firmware has 4096 levels.
    See file "max_brightness" - /sys/devices/leds-qpnp-24/leds/wled:backlight. Maybe this information will help to fix this problem. Sorry for my English, I used a Google Translator

    Sorry for the many posts, but I found another problem in the latest official build of LineageOS 17.1 (from 11/17/2020)
    Wi-Fi works only in b/g modes, if in the router settings you set the network to work only in n mode, then the phone cannot connect to the network - it sees it, but nothing happens when you try to connect. Reboot doesn't help. What could be the problem?

      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!

      It's been a while since last time I did test a new Android version on this smartphone.
      First of all, I'd like to thank you all maintainers for your effort and to congratulate for the great work done with this first build of lineage 18.1.
      I did some basic testing (don't expect anything too accurate, since this is not my main device for a while) which I'll resume below:
      • Booting was fine and time is quite comparable with previous lineage versions
      • I succesfully installed a test build of OpenGapps (micro configuration of 20210130), which seems to work pretty well
      • account setup and sync works
      • WiFi working at both 2.4/5 GHz
      • Bluetooth working fine, I had no problems connecting to my bluetooth earbuds and listen to some music
      • NearbySharing is working like a charm and quite fast too
      • online charging is working at full speed (about 1800 mA with a quickcharge 3.0 wall charger)
      • MTP working
      • OTG works for both input devices (mouse, keyboard, etc..) or mass storage
      • camera is fully working (taking pictures with both front/rear cameras, taking videos, flash)
      • 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
      • audio is fine
      • video playback also seems to be fine (tested on youtube at 1080p)
      • chromecast works, in fact I did cast screen and youtube to a Google Nest Hub without any problem
      • the OS is overall responsive and snappy, even with gapps installed
      • screen rotation, accelerometer, gyroscope, proximity sensor, etc.. all fine
      • double tap to wake and other classic gestures are fine
      • I couldn't test hotspot since, as I said, I was stuck at 2G connection which was quite unresponsive
      • unfortunately I cannot test GPS or NFC neither
      I hope I did not forget something important.
      I'm going to keep this installed since it's really stable, so feel free to ask me for some other testing and I'll for sure try to do that as soon as I have some spare time :)

      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.

      - 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.

      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!
      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!

      This occasionally happens to me when flashing the Z3C and other Sony devices. I can usually get round it by taking the following steps in TWRP:
      1. Backup your data partition
      2. Format - not just wipe - the data partition
      3. Flash the new ROM - I usually do it by installing from SD card, but `adb sideload` should work too
      4. Boot the phone and go through the setup wizard app, setting any screen pattern or PIN you had previously.
      5. Restore the backup of your data partition
      I hope that helps

      Thank you very much ! It was indeed the right procedure !

      It saved me a lot of time. Thanks.

      Installation:
      If you are on stock OS, you need a custom recovery first. You can get the recommended recovery in the official installation instructions link below.
      If you are coming from stock or other ROMs, you need to make a factory reset.
      As always, make sure to backup before installing this ROM.

      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.

      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?
