Please everyone who updated about Flamefire 20210422 to 20210603 share a short review with the community, thank you.

Dirty install over the last 17,1 release (1.7). Everything went smoothly, I wasn't using magisk before so can't speak to that.

Previously the SafetyNet test would fail on CTS profile match but now it passes so I guess that's an improvement ^_^

Weirdly enough before I had one app (experian) which started to refused to run a while ago (saying phone was rooted - it's not, only bootloader is unlocked). Now it works fine. However the santander app which was running fine before now refuses to run (same reason - because it thinks devices is rooted). I was able to fix it by deleting the TWRP folders in internal/external storage... what a stupid security check!

All other apps I had (revolut, lloyds, and others) seem to work fine.

4G seems to work fine, even after reboots (before I had to boot with 3G and switch to 4G to get service). I had to manually select the right modem (hutch uk) after enabling IMS features though.

Thanks. I thought that was the case. Time for some detailed comparison of vendor repos :)
And it's nothing to do with the software or the vendor blobs - it's my phone. The stock camera hasn't worked in any of my recent builds on my development phone. It didn't work in @Flamefire's builds either. Tonight I backed up my daily driver, flashed @Flamefire's latest and the stock camera works fine. Works fine in all my recent builds on this phone too. So sveral days chasing a softwarebug or build problem that doesn't exist :) Time for a new development phone I think

There is a bug where device does not vibrate after reboot if the device battery completely runs out of power and you recharge it.

I have only notice this in Lineage OS 17.1 and is the same with Flamefire's May security patch version.

The only way I was able to get vibrate after reboot back was by flashing stock Sony OS.

Also another bug for do not disturb where events in Simple Calendar Pro notify with sound even though do not disturb is enabled with events settings is set to not allow in do not disturb mode and I checked in app notification settings, it is set to not override do not disturb.

OS is Lineage OS 17.1 Flamefire's May security patch version.

I'm running into an Attestation Failed error with this ROM, even when using Magisk Hide, and the Universal SafetyNet fix version 2.0test. There is a discussion on the issue here:

however, the developer stated he is not working on the issue as of now. As of now, basicIntergrity passes, but ctsProfile fails with evalType BASIC.

This issue makes using Google Payment impossible with this ROM.

I've been looking into the Android 12 beta lately, generally I'm not a fan of less efficient use of screen space, but the larger quick-setting tiles could actually be beneficial on a small device like the XZ1C. I've also been hearing that its "20% more CPU efficient" over Android 11 (yet to be proven). Regardless, I'm sure we would all enjoy some extra battery life if it turns out to be more power efficient in any capacity. I'll certainly be interested to see how it performs on our device once (hopefully) it is eventually ported as a new LineageOS version. Interesting stuff! Once again, a huge thank you to the modders on this thread like @modpunk and @Flamefire for keeping the XZ1C alive.

Now that Modpunk is back, do we know if there will be any updates to LOS 18.1? Latest security patch is January...

I know we've got Flamefire's 17 with more recent patches, but not sure I can downgrade successfully. An updated 18 would be preferable.

    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
