Bad network signal

Good time! I put this assembly, in addition to the known bugs (usb-tetering / android auto), there is one more important one. A bad signal from the network of the mobile operator. I did not observe this on other firmware. Is there a solution?

You have to flash January 2020 firmware after flashing the rom. Every time you flash/update the rom you have to do this. Rom has included old may 2019 firmware. January 2020 is the most stable in terms of cell coverage.

Install all modem firmware from June 2019 - April 2020 one by one.

Also, ignore the low signal in the statusbar. The previous maintainer disabled something (find in this thread, I forgot the name) so the signal statusbar display the real strength of the signal instead. :)

Sorry for the maybe stupid reply, but does your user have sufficient rights to read/execute the file?
There are no stupid questions! Thanks for trying to help.

You can see in the second code snippet, that I do have permissions to read the symlink. But as I told in the description this symlink points to a nonexisting file. That's no problem, because the symlink should be itself integrated in the LineageOS image and will point to a valid file on our beloved tissot.... but unfortunately the build system (soong) does check the validity of the symlink on my computer and then errors out.
The fix will probably be to just tell soong (respectively ninja) to not follow the symlink and proceed even if the file is not there itself (use lstat instead of stat).

There are some new critical security patches and therefore I increased my efforts in fixing my build issues. I was able to find a workaround and probably identify the root cause. More importantly for you, I was able to build again! :D

lineage-16.0-20200613-UNOFFICIAL-beneter-tissot.zip | Checksum | Signature | Security Patchlevel: 2020-06-05





Also I was creating my build scripts on the fly, so I will be able to publish them soon.
Hi @Beneter I have been testing the different firmware versions i now i can say without doubt that January 2020 is the best firmware in terms of cell reception and call quality in areas with weakest cell signal. Please upgrade the built in firware to this version because every time rom is updated it reverts to old firmware. If you need the firmware package i can share it with you.

first of all thanks for keeping lineage 16 on tissot alive,
second: i don't get thru this twrp treble stuff, after i installed your ROM for the first time i could boot in twrp as normal. After i installed the last update twrp was gone (also magisk) and only the Lineage recovery was left. Do i always have to reinstall twrp after an update or is there another way? I had Giovix92 TWRP version with treble support installed.

You have to flash twrp always after update. And magisk after TWRP installation (after reboot to recovery).

    LineageOS (LOS) 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 (AOSP) 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.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit Gerrit Code Review. If you want to report an issue please do so on GitLab and include a logcat if possible.

    Status
    This Project is EOL, please use official instead.

    Known issues
    USB Tethering / Android Auto not working
    OTA Update not working (might change in the future)

    Instructions
    TBD

    Migration instructions

    If you are coming from Official LineageOS 16.0 you need to clean flash (wipe everything incl. data) or migrate the signature keys before flashing:
    1. Backup your data (I recommend Titanium Backup)
    2. Boot Recovery
    3. Nandroid backup
    4. Flash migrate-official-to-beneter.zip (s. Google Drive)
    5. Flash lineage-16.0-*-UNOFFICIAL-beneter-tissot.zip (s. Google Drive)
    If you are coming from anything else please do a clean flash (wipe everything incl. data).

    Downloads
    Unofficial Build: Google Drive, There will always be checksums and detached signatures signed by my key "38E50B61" (s. below).
    I encourage the community to host mirrors with the same filename. If you download from them, be sure to verify the PGP signature.
    Recovery: TWRP
    Google Apps: Open GApps (I am not using any GApps but microG by NanoDroid, if you would like to use GApps please flash the nano image for arm64 and install additional Apps from PlayStore)
    Root: Magisk

    Signature verification
    TBD
    Code:
    gpg: Good signature from "Stefan Benter <[email protected]>"
    Primary key fingerprint: [B]E545 73C1 5218 8816 E83C  3A0F DCAC EF53 38E5 0B61[/B]
         Subkey fingerprint: 1DE2 E0FE 948E EAAB B446  D398 A4D6 CD34 239A B40D

    Why don't you submit it to official?
    I was asking them what would be needed to be accepted as a maintainer, they told me to fix the USB tethering issue and port to 17.1. I am not saying, that I will never do so, but I do not want to promise anything as of now.

    @Beneter You say you use nanodroid. Does that mean your ROM supports signature spoofing out of the box?
    No, this is 100 % vanilla LineageOS as of now. I am pretty satisfied by the NanoDroid Patcher.
    I would be able to provide a second build with signature spoofing enabled (in restricted mode), but this would cause a small amount of additional effort.
    @everyone: Small poll - If you are interested in an additional signature spoof build (only really needed for MicroG) press thanks on this post. I will probably implement it if we reach five people.

    Hi,
    as you might have noticed, the new security fixes where merged to LineageOS.
    Unfortunately I am facing some build errors and therefore am not yet able to provide a new build.
    I'm on it!
