I had (probably) the same issue with Magisk disappearing.
I believe the survival addon of Magisk stopped working. Usually, Magisk installs a small script that is executed when you update the system and reapplies the patch to the new boot image.
For some reason this stopped working (probably since the last two builds).
Therefore you need to re-patch (or reinstall) Magisk everytime you update the system.
Does anyone have an idea how to fix the survival addon?
Now I have flashed Magisk anew without uninstalling anything before. All went well an all works as it does before I did the LOS update without the need to reconfigure anything.
Chris, you have contributed so much good to the community, we really love you. I can confirm, too, that the latest build works like a charm. Thank you so much, mate!
Could you provide more details? How exactly did you install the patch? (sha1sum of ā/vendor/bin/netmgrdā should be ā6d953fa4d4614ff6a56db9b7078be343da093e44ā as changed in upstream) Are you on lineage-17.1-20210129-nightly? Do you really have an 4G Symbol instead of LTE, havenāt noticed it yet on my phone. Otherwise something special about your phone installation?
As Chris @chrmhoffmann already stated above could you update to the current lineage and report if the problem persists? If yes, we would need a logcat with errors related to netmgrd.
Note: As far as I understand, there could be different behaviour if you install the latest official modem files provided from fairphone here after the lineageos install, but I think that this would be out of scope of lineageos and there surely will be other incompatibilities.
@chrmhoffmann , was the previous netmgrd binary from official fairphone A6 blobs?
Because I am using the one from that and did not notice this issue. Have been using it from quite a few days.
Note: this modem zip isnāt provided by Fairphone and isnāt official but was pulled by the community from each latest FPOS release.
As the last update of the modem files was with the last update of A6, i.e more than two years ago, and LOS should already contain this latest version if you had a FPO(O)S version installed before installing LOS which was higher or equal to the latest A6 FPO(O)S, you already have the latest version of the modem files, and there isnāt any reason for which flashing the latest zip should change anything.
Edit: Corrected my statements, thanks to @chrmhoffmann for the correction
Hi, the LTE connection is coming back reliably again on my phone as well. Yet I have another problem now. Since it seemed a little too much to put it in here, I created a separate topic for it, yet Iāll leave a link here, just in case itās acutally related to LOS:
I just recently switched from LOS 16 to LOS 17.1, so I am almost late to the party.
The upgrade worked well, big thanks to the developers and everyone who contributed to the release.
