I updated from 1.5 to 1.7 and since then I Mobile network 4G does not work. I have to set 3G to use phone services at all. Also the WiFi switches off and on all the time. o_O
So, I tried a downgrade to 1.5 again. But that doesn't work either; it does not boot and going straight to TWRP.

Does anyone please have a solution? How to reapair "Mobile network" or how to downgrade without having to start from scratch and install and configure 200+ apps manually.

Set Preferred network type to 3G, and reboot the phone. after phone is booted, switch back to LTE

Thank you; the phone did not freeze again and WiFi seems also to work more solid. For a few seconds I had a "4G" symbol after switching back to 4G Preferred network type. However, now I only get a "H" or "H+" symbol. Does that mean HSDPA and not LTE?

Very well, the monitoring app says it is connected to LTE. So I keep watching.
Many thanks for the fast support, Rubik.Orange.

I figured that it is required to toggle to 3G before every reboot of the cellphone and switch back to 4G after the phone restarted. Once forgotten, you are offline for calls and mobile data.

Can anyone confirm this odd behavior? Probably a downgrade to 1.5 it is the best option for my Xperia XZ1C? Is a downgrade possible without the TWRP loop?

Yes, I can confirm this. I did a fresh install. I am using the O2 Network in Germany

Did it work without the workaround after a fresh install?
Same issue here as well. It can be resolved without reboot for me by repeatedly toggling 2g 4g and airplane mode(no particular pattern) do this until the 4g registers LTE in the top bar. Upon reboot, it 100% fails to register and I have to do this but it also does this anytime I enter a dead zone and out again.

Similar behavior on my end. However, it sometimes works, sometimes does not. Most times, I need to switch to 2G/3G after a reboot, but not always. Same thing for out of service areas. Most of the time it will reconnect automatically but sometimes I also need to fall back to 2G/3G manually. This is particularly annoying when driving longer distances.

Yes, I can confirm this as well. In about 90% of all startups, the phone does not connect to the network and WiFi is shaky (network: Telekom Germany, modem config amss_FSG_lilac_telekom_germany_volte_vowifi_tar.mbn).

My workaround for the moment:
  • switch to 3G
  • wait until it connects
  • leave it there for a while (a minute or so)
  • switch back to LTE.
When I have gone through this process, connection seems to stay stable until I disconnect from the mobile network by e.g. turning on and off airplane mode. Then it stops working again.
I am almost completely at home however at the moment thanks to Covid, thus no switching of mobile network cells etc...

The phone worked flawlessly with 1.6.

In case anybody can point me to an instruction how to create/open e.g. log files I will be happy to provide further information.

Edit: phone runs fine (albeit without VoLTE) if I choose amss_fsg_lilac_telekom_tar.mbn.

Weird. As I wrote above, I had a similar problem but it was solved for good after I changed network type to 4G preferred in Settings.

Yes, that was what worked for me when I switched from 1.5 to 1.6 - for some reason however this did not do the trick this time... maybe it has to be done in a special order. I remember starting with 1.6 in 3G mode, then switching to 4G directly before the next reboot. This time, I rebooted sveeral times before I remembered I had to do this (phone is shut down every night)

Is there some way to re-execute the initial modem configuration that is executed during first boot after the update (apart from - most likely - reinstalling)? I would like to try redoing the process I followed on 1.6.

had the same issue, a warning message about how google play services does not support it

I don't have a car to test, but I can install, configure, and launch the Android Auto app.

Are you using Magsik and/or EdXposed? I noticed that Magical broke right after installing 1.7, and a few days later EdXposed no longer worked. I had to go to Magisk Beta, and EdXposed Canary to work around that. On EdXposed Canary, there was recently a bug that stopped banking apps from working correctly. Might be the same for Android Auto.

I tested this version "lineage-17.1-20201217-UNOFFICIAL-v1.7-lilac.zip"

Another problem, No service with my card SIM bouygues telecom.

Voila Voila ;)

Go to settings, carrier settings, set preferred network to 2G. Wait for a minute or so. Switch preferred network back to LTE. This issue was mentioned a couple of times during the last week.

    Ok got it working and running the new 17.1 for a day now on my phone, have it here: https://www.androidfilehost.com/?fid=14943124697586359584

    - June security patches
    - 4.4.272 kernel (thanks to derfelot)
    - Usual modifications to pass SafetyNet w/o Magisk
    - Few fixes related to GApps permissions (maybe)
    - New/Updated APNs (thanks to LOS and linckandrea)

    The 18.1 version with the same changes is at: https://www.androidfilehost.com/?fid=14943124697586359658

    Again: I only tested the 17.1 build. The 18.1 should work but may bootloop or have other issues.
    I recommend (for both builds) that you have flashed TWRP to the recovery partition on the phone and have a working ROM zip on the SD card (e.g. what you currently use) to be able to boot the phone back to recovery and reflash the old ROM in case of bootloops etc.
    And as usual: Have your data backed up!

    Thanks. Dirty flashed the 17.1 and it seems to work well.

    Will try the 18.1 soon. How should I install it? Would dirty flashing it over 17.1 work?

    LATER: Happy to report dirty flash of 18.1 worked well. I see no major changes except for stock LOS camera (which, like on most Sony 18.1 ROMs, has a problem with auto exposure). Otherwise, looks very promising.

    Still EAS kernel? Is 18.1 also?
    The EAS kernel is awesome!
    Yes. Both use the same kernel

    Select 'Access Point Names' and right up select + and configure You own apn.

    Hey guys, first off thanks a lot to modpunk and flamefire and everyone else here to put in the energy to keep our beloved phones updated.

    This weekend I installed the very latest 18.1 from flamefire and it works fine so far. (I installed it clean, no dirty flash, completely started over with the Sony stock ROM via EMMA and then did a clean 18.1 install following all the right steps)

    Now there is one major bug that I somehow cannot find a solve for and I hope someone could help me please. Sometimes and all of a sudden the mobile network just disappears and it says 'the cellular network is not available'. I cannot even select it under Settings to switch between 3G and LTE as it is grayed out. After I restart it comes back though.

    Now, what is odd is under 'Settings / Wireless & Internet / Mobile Network' I cannot select and manually define the Advanced settings for the carrier AT&T (see 2 attached screenshots at the bottom). There for whatever reason it only says 'To disable this SIM, remove the SIM card'.

    Shouldn't there be a menu similar to the TELUS screenshot that let's me define the preferred network type, calling, Network access and so on?

    I know some people here had the same issue, but was wondering how it has been solved.

    Thanks a lot!



    (Edited: Wording, sorry I did not mean APN but the 'Advanced' settings for the network carrier)
    I see that effect after inserting ("hotplugging") a SIM card without rebooting.
