[ROM] LineageOS 17/18/19 UNOFFICIAL - (Update: 2023-08-26)
- Thread starter Flamefire
- Start date
Hi guys. For clarification:
As I understand, /system contains the OS, system apps, /etc and the like.
Meanwhile, /data contains user data, user apps and their configs.
Before freshly installing LineageOS to a new device, I usually wipe or format /system and /data, which seems to work fine.
Although, the installation steps state to not wipe /system when coming from stock rom. Does that mean there are some files present in the stock OS that don't come with LineageOS, but are still needed in the future?

No. There's no point / need to wipe /system, because it will be overwritten when you flash the custom ROM
Could you compile 17 with this?

Why does my phone randomly connect and disconnect from WiFi and sometimes say blocked or just not even connect? I'm pretty sure I remember this happening last time I tried this ROM. When it does connect, the WiFi works even though Android thinks it doesn't, but I can't use it for long.
Edit: Enabling Airplane mode and rebooting, then waiting and disabling it fixed it. Mobile data also connected when it wasn't during all this.

@3ncryptet and anyone else interested:
For the June update I wanted to add a setting to change the fingerprint behavior when the screen is off. After I finished it for 17.1 I noticed that LOS 19 already has that built-in: It is this one @Arcline mentioned.
Hence I backported this for 17.1 & 18.1 instead so that everyone has it now
This is a known issue with the modem driver and 4G which doesn't work well. Switching the phone network to 2G or 3G and waiting for a data connection then back to 4G solves this
Many thanks for the update @Flamefire!@3ncryptet and anyone else interested:

When battery charge manager for 18.1? Thanks@3ncryptet and anyone else interested:

I can confirm that. Awesome work @Flamefire, thanks a lot!
I can add: With the "SaverTuner" from F-Droid I increased the battery life from 2 days to 3 days by using the "Moderate" power saving setting.
Great work once again! With the june release, 18.1, I notice that often I can't use the fingerprint to unlock the phone when I wake it up. Anyone else or is that just me?
Because of this I wanted to revert to the previous build, the may 19th or so build. That doesn't even boot to the lineage logo. Updating to the june one again makes it boot again but fingerprint has issues. I tried until the first April update, but none of them would boot anymore.
Is there any reason I can't downgrade? All 18.1 btw.

hello everyone, I encountered this problem in both versions 17.1 and 18.1: Google wallet apk after the first two or three days of normality, no longer contactless payments works because it warns me that the phone no longer satisfies the security requirements... I tried disabling updates but with no success...( I have not installed magisk ). Open gapps installed.

Likely not, I just noticed that I often had to turn up the volume of my (wired) headset to max in some apps and it was (only) just enough, so I increased that (output) volume a bit.
I'd actually expect that because there is some tight system integration of the Sony camera on 17.1 which isn't possible on 18+ anymore (which is why it was excluded) and the port seemingly just gets the app itself back without the full integration
FWIW the basic & CTS attestation (aka SafetyNet) works on the ROM which seems to be enough for most banking apps and at least Google Pay/Wallet. But I guess you already tried that it isn't enough for your banks app so I'm happy you found a workaround at least.
I had only added the links to my profiles about page so far, but now added it also to the OP.
And yes I do appreciate the couple donations I received so far from various people as while it is fun it is also quite some work, especially with the backports to 17.1 and the occasional feature addition1Wanted to share my story and thank the maintainer. I found this ROM while searching for recent Android 10 options for Z5 Compact and thought to myself, wow that's exactly what I need and even though I also also have a XZ2 Compact I went and bought an XZ1 Compact just to try it out. Guess what, it's a great experience so far! Maybe I keep it and give the XZ2C to my wife...
. Thank you so much @Flamefire for your effort to backport current security stuff to Android 10 for this great device! -
56LineageOS 17/18/19 for Sony Xperia XZ1 Compact
RELEASE
This is an alternative ROM for the Sony Xperia XZ1 Compact.
Creating this to honor the great work of modpunk and derf elot from https://forum.xda-developers.com/t/rom-lineageos-18-1-unofficial-2-0-update-2021-01-20.4047763/ which seems to be discontinued. Posting an own thread to keep the latest versions visible, I'm NOT claiming authorship over the ROM.
I basically just build the ROM using the latest changes from upstream LineageOS/Google and kernel updates (usually incorporated by derf elot ) See my post.
FEATURES
- Signed with dev keys
- EAS kernel
- Passes SafetyNet out of the box (thanks Rooted_Ansh, Havoc-OS Team and kdrag0n)
- Seedvault (Video)
- IMS support (thanks to Rooted_Ansh and also Shujath)
- 17.1 has stock Sony camera (not possible on 18+)
DOWNLOAD
You can download the latest release here.
HINT: Download both the ZIP and md5sum file so TWRP can check the consistency of the upload/download.
Make sure you download the right version, vanilla LineageOS is named lineage-*UNOFFICIAL-lilac.zip while the MicroG version is named lineage-*-MICROG--lilac.zip
REQUIRED FIRMWARE: 47.2.A.11.228
IMPORTANT: I only test the 17.1 releases myself. The 18.1/19.1 are build from mostly the same sources and hopefully work. I only test them roughly.
Backup download
INSTALLATION
IMPORTANT: Magisk seems to cause issues (bootloops) on update, so remove it first and reinstall if required. Note that Magisk is usually not required unless you want root.
- Put the zip file of the ROM on your SD card or internal store and boot into recovery.
- When coming from stock ROM, do a full wipe (i.e. factory reset) via "Wipe". You don't need to wipe system. When flashing the stock ROM you can select to not keep user data which is equivalent to this step.
- Go to "Install", select the zip file and add optionally the gapps zip. Then flash it.
- After updates you may now wipe cache&dalvik (option after install)
TWRP 3.3.1-0 by modpunk / derf elot
Or use the latest TWRP for 17.1/18.1 or TWRP for 19.1.
3.7.0 Seems to work well with latest updates (decryption working) but LineageOS 19.1 (Android 12) requires the ones with "_12" suffix, e.g. 3.6.2_12.
For ease of use I suggest to flash this recovery (only required once):
- Boot in Fastboot mode: Hold "Volume Up" while connecting the USB cable to phone and PC
- Flash TWRP by running this on the PC: fastboot flash recovery twrp-3.3.1-0-lilac-android10-1.img
(adjust the filename if necessary) - From now you can boot TWRP by turning on the phone with "Volume Down" + Power
Upgrades between versions
Dirty-flashing (e.g. from 17.1 to 18.1) works well but you have to also flash a GApps version matching the Android version or the device will bootloop.
For the upgrade to 19.1 you may need to fully remove OpenGapps by wiping /system and install e.g. MindTheGapps.
SUPPORT
There is NONE. If you have any issues or question ask in the thread so maybe someone else knows the answer.
I'm just providing the ROM (Lineage 17.1 variant) I use myself for others to try to and just build the Lineage 18.1 ROM without much testing.
If you prefer to use a more well-tested Android 11 ROM, I suggest to look at Havoc-OS.
Contributions to the sources are welcome and likely get integrated into the next release.

18April updates are out, enjoy! Again I had to backport every security patch from 18.1 to 17.1 so it really seems to be dying...
I might switch to building LOS 20 though as derfelot doesn't seem to be providing updates anymore. And especially the battery charge/protection service that might be coming there looks promising...
Sorry no. I'd need to research how to create that recovery and maintaining 3/6 different ROM versions is already enough work especially with the hugely increased time/effort to keep LOS 17, so I can't afford to do even more.
