I'm uploading a new ROM version 1.1. Should be up in 3 hours (yes, I only have 1Mbit/s upload).

Hi modpunk. I have just sent you $3 on paypal for this release.

Sorry its only $3, but its all I have in my paypal account at the moment. After covid-19, when I have a working credit card again, I will definitely make what ever donation I can after each release.

I write this post in a hope that somebody else will match my $3 and donate to you - as well as getting some cash to derf elot.

I hope we can identify who are the people who should receive the funds from the community on this thread.

I have the same problem with the default calendar app. Synchronization with DAVx5 and Nexcloud seems to work, but you cannot add or edit any entry, the calendar app does not have any settings, and it does not show notifications for upcoming events.

The default calendar app is working now in 1.1, thanks!

I have one more question I could not find an answer to: How do I delete "LineageOS stock apps" like Browser, Email, Gallery, Music,...? In earlier versions those apps could be easily found in system/app or system/priv-app, but in 17.1 those apps don't have their own folders anymore.

Thanks Modpunk !
I chipped in $ for the effort, and will gladly do so each month for every release.
This is professional work and solid programming, so a thousand thank you's for the service you two !

My carrier started offering free VoLTE calling. Is this an option with our Sony's ? I can't find a setting for it.

To the guy above:

The camera won't work right after the flashing, but after a few hours of charge it will. In any case, it won't have the gallery linkage so you can't take a pic and then view it from the camera... You have to exit and open the gallery, which makes the app useless. Just install Open Camera. The whole camera situation in this phone is retarded regardless of ROMs. But at least Sony let us unlock the bootloader :)

Regarding dirty flashing, I don't like to dirty flash from Android 9 to 10, although most would say it is fine... Even on Stock Android, they dirty flash you the updates.

I thought that it was just the Sony camera app, and not the camera itself? So the hardware won't work until I charge it up? And what about the Snap camera (default LineageOS camera app)

wifi not working

I'm uploading a new ROM version 1.1. Should be up in 3 hours (yes, I only have 1Mbit/s upload).

i clean flashed v1.1 onto a fresh newflasher .228 stock rom (that matches my region/operator). stock rom booted fine, was able to connect to wifi

but upon booting up into LOS, wifi cannot connect (error message says "failed to connect to network" even without trying). when trying to add a network manually, i get an error message "failed to save network"

am i missing some setting somewhere? mobile data seems to work fine. thanks for the help!

EDIT (Solved): i wiped data just before installing LOS (and after logging into the stock rom on initial boot). this solved the wifi issue

Go-to settings then system , expand it by clicking advanced then, go-to developer options switch of the toggle at the top most part of the screen( switch of developer options).

I was trying to build the rom, but there are always some files missing when I do extract-files.sh. I have already tried stock roms from a number of different regions.

The missing files are /vendor/bin/ffu, and a couple of *.so for several camera apps in priv-app.

Where could I find those files?

Edit: Also the rom I built boot loops. I cannot even connect adb to it. All I can get is kernel logs after it reboots into recovery. So all I know is some services are crashing (xtra-daemon, qti_gnss_service, zygote, etc), but not why.

Is it because I am missing those file, or is the files I extracted just wrong? I sampled some of the files and compared with the image I downloaded, they seem mostly equivalent.

    LineageOS 17.1 for Sony Xperia XZ1 Compact



    This is an alternative ROM for the Sony Xperia XZ1 Compact. It offers several privacy features and F-Droid App Store preinstalled. If you're coming from LineageOS 17.1 you can simply update! No need to wipe anything.

    • Signed with dev keys
    • FDroid preinstalled
    • FDroid Privilege Extension
    • Well tested but some bugs maybe included


    You can download the latest release here. Check the ChangeLog below for firmware requirements!


    Put the zip file of the ROM on you sdcard or internal store and boot into recovery. If you use my TWRP recovery, you should use that one to flash the ROM.

    Make sure you select Zip signature verification.

    This will make sure the zip file has not been altered!


    • UnifiedNlp doesn't work with LineageOS 18.1 yet
    • Spell checking doesn't switch if you change keyboards
