So, here are the results.
Pic 1 is outdoor, mobile data on, running system.
Pic 2 is outdoor, mobile data on, after a reboot.
Pic 3 is outdoor, mobile data on, 2nd fix few minutes later.

Hope it helps, remember, it's my Z3, not the Z3C.

To (all) users who want to help us with some GNSS (GPS) debugging: Could you please report if you have GPS working with Arian's latest build (10 Aug 2020)? Please report if you have an active SIM card in your phone. If it does not work with a GPS fix within 30 seconds max, plese try again with the phone in Airplane mode.
For me if LPP_PROFILE set to 1 or 3 then there is no GNSS on LTE network, though it's working in 2G and 3G.
And no any issue If LPP_PROFILE = 0 . Apparently AGPS is working as it gets ~10-12 satellites after cold start and internet off. It took ~70 sec. to 3D fix outdoor
XTRA injection also work, resulting in instant fix with internet connection

Hi there!

I have built an update for z3c.
This build includes latest lineageos sources and a few device side fixes. It would be cool if you can specifically test GPS, audio and the time after a reboot.
At all this build should be release quality. Please report back if there are any further issues.
You can download it here: https://sourceforge.net/projects/ephedraceae/files/z3c/lineage-17.1/
If nothing goes wrong i plan to go official 17.1 within the next days.

Happy flashing!
Is something going wrong?

WiFi connection problems & system encryption

We are happy to announce that Z3 and Z3 Compact are being shipped on 17.1 officially now. I will create a new thread within the next few days once there is a build ready.
GPS was fixed by Tom.
Greetings, Arian :)

Thanks, just installed 17.1-20200908 today!
I'm running into problems with my WiFi connection. Can't seem to connect to my home router anymore, which is really annoying. I read somewhere that this could be caused by the MAC randomizatino of Android 10.
Furthermore, my device won't boot after I start the encryption process (LOS loading screen crashing into recovery menu after a couple of minutes).
Have not tested the GPS yet, which stopped working for me a couple of months ago on LOS16.

    Thanks for this early feedback. I just downloaded the first official build as well and I cannot confirm the issues.
    • Regarding WiFi issues, could you please state the country you are in?
    • Regarding encryption, please set a pin/password before(!) you start encryption. There is a known bug that encryption might fail if no pin/password is set.
    • GNSS (GPS) working OK, including GLONASS & BEIDOU

    WiFi: The problem was with my meshed WLAN at home. I changed some SSIDs of the access points and it's working now. Though I didnt had this kind of problem on LOS16.
    GPS: I just did a short test on Google Maps. Seems to work now, without relying on additional Google location services.
    Encryption: I'm pretty sure I set a security code pattern before I started the encryption process. But there seems to be a similar bug reported ons LOS GitLab (Issue #1027). Something regarding the partitioning.

      OTA and TWRP recovery

      Over the Air Updates
      My upload script automatically pushed OTA updates to my GitHub.
      If you want to make them visible through the Updater you can flash the attached magisk module LineageOS-17.1_z3c-OTA-v1.zip or add the line
      Code:
      lineage.updater.uri=https://raw.githubusercontent.com/ArianK16a/OTA/lineage-17.1/z3c.json
      manually to your build.prop. You should use the recommended TWRP so that the updates flash fine.

      TWRP recovery

      TWRP 3.3.1 for our z3c with Android 10!
      The TWRP for Android 10 is attached to this post.
      Source is available at: https://github.com/z3c-pie/twrp_device_sony_z3c/tree/android-10.0

      Changelog for twrp-3.3.1-1-z3c-20191212-sar.img
      • Improved System as root support, /system is a symlink to /system_root/system now

      Changelog for twrp-3.3.1-1-A10.0-z3c.img
      • Added Bootlogo, booting from offline state will display the original sony logo now instead of nothing
      • Fixed fastboot boot
      • Updated kernel cmdline from 23.5.A.1.291

      How to install this build:
      • Reboot to fastboot by holding volume up while connecting your device to your computer
      • Open a terminal and move to the directory with TWRP in it
      • Rename the downloaded image to twrp.img
      • Type
        Code:
        fastboot flash recovery twrp.img
      • Boot into TWRP while the device is powered off press the power and volume down button

      Feel free to ask questions or give feedback about TWRP here .

      Have a nice day!

      Additional information about the recovery on this device:
      First of all we should make the basics clear: On our Z3 Compact we have got a bootloader update which can boot a recovery from powered off state by pressing volume down and the power button. Because we haven't ever had this updated bootloader and not all sony devices received the update, there have been some intelligent people who brought a special init binary which can handle recovery boots during a normal boot. This means when using advanced reboot from the ROM or pressing a volume key while the sony logo appears at boot. https://github.com/LineageOS/android_device_sony_common/commits/lineage-16.0

      To make this work there is this method to extract the ramdisk: https://github.com/LineageOS/androi...eage-16.0/extract_ramdisk/extract_ramdisk.cpp which uses zlib to decompress it. So far so good, zlib can decompress the default compression for recovery ramdisk which is gzip. However LZMA is more effective to reduce the size so we took it's advantage: https://github.com/omnirom/android_...mmit/885b01223a460d3f2500155ea415bdc8573679bc in order to fit recoverys compiled from recent environments (android-9.0 in my case) into our small FOTAKernel partition.

      According to this change the init_sony can't handle the recovery boot anymore because it can't decompress the recovery's ramdisk so nailyk and Diewi (as far as i know) added support to decompress LZMA compressed ramdisk's with this chain: https://github.com/sonyxperiadev/device-sony-common-init/pull/20/commits
      However these commits have never been merged into the LineageOS/android_device_sony_common nor the sonyxperiadev/device-sony-common-init. Since your ROM, CarbonROM, is using a fork of LineageOS/android_device_sony_common is missing these commits the recovery boot fails with a kernel panic, like this: https://del.dog/egawososux.htm

      So you can either use a recovery which doesn't compress the ramdisk with LZMA (for example the one from here: https://forum.xda-developers.com/z3-compact/development/recovery-twrp-3-2-3-0-aries-t3837192 or ask your ROM developer to pick the according commits into the sony_common tree/use my fork of LineageOS's one https://github.com/z3c-pie/android_...mits/fa85dfcc07f42d73f9a1abf1f4c82d8bf0486a93 which would enable you to use recent TWRP builds with a LZMA compressed ramdisk.

      I hope i presented it clearly and in the right way,
      Have a nice day!

      EDIT: Minimized patch for LZMA is available here: https://review.lineageos.org/c/LineageOS/android_device_sony_common/+/252923

      The new build is up!
      Get it from here: https://sourceforge.net/projects/ep...age-17.0-20191002-UNOFFICIAL-z3c.zip/download
      Make sure to use the new TWRP from Post #2 because Android 10 introduces System-as-Root which can lead to weird behaviour in the old TWRP.
      Note that there are not all features from LineageOS 16.0 ported over yet and there can be unexpected, yet unlisted bugs.

      MY personal hardware support list can be found here: https://gist.github.com/ArianK16a/1e46c463a5c910efb322d9cf0e16c3c0 but as always, i can't guarantee you anything!

      Happy flashing!

      MOD EDIT: quote removed

      While I appreciate the advertisement, its absolutely disrespectful to Arian to advertise it in *this thread*. It's like going to Ferrari and showing all the customers that Lamborghini released a new car...
