INSTALLATION
Before first install: flash and boot into the TWRP provided in this thread, format data, reboot to recovery and wipe all internal partitions, then flash the ROM, GApps and root (if needed).
Note: There is not going to be a LOS su addon anymore. If you need root, flash a root manager of your choice. No guaranteed support from LOS for this.
When updating from previous builds, simply dirty flash the ROM is enough, decryption in new TWRP works now
Recommended GApps: MindTheGapps provided in this thread.
KNOWN ISSUES
Stock camera is not working anymore due to incompatibility of stock library (libimageprocessorjni.so) with new libgui
Currently, LOS isn't feature complete yet, so some things, buttonn, advanced menù etc. may be still missing
You tell me...

---------------------------------------
Changelogs:
v1.2 (2023-05-10):
- Updated to T QPR2 release (LineageOS upstream)
- Updated to May 2023 Security updates (both ROM and kernel)
- Our kernel now includes updates by CIP and is up-to-date with tag st40 - thanks also to Flamefire for help with some of these (1)
- Reduced zram size to 25% (1gb) of out total RAM to have more to use freely
- Updated BT stuff for QPR2 (maybe offloading is working again? needs confirmation)
- Added the option to reflash the mbn via OpenCS (see Xperia Parts) - thanks also to shank03 & Flamefire (2)
- Fully enabled IMS on Congstar Germany via overlay on lilac
- Possibly some battery/performance optimizations here and there
- Fixed Android Auto support
- Added new LineageOS "Charging control hal" for battery charging care (3)
- Maybe more I forgot...
(1) The CIP kernel includes fixes for issues and security vulnerabilities from 4.14 kernel (see https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git)
(2) A somehwat lengthy explanation: This option is off by default on fresh installs. When upgrading, this should be enabled because we enforced this for everybody previously. However, this option is only required for certain carrier mbns that enable IMS. Personally, I know that the O2/Telefonica Germany mbn needs this, otherwise you get a crashing modem at every boot (unless you switch to 3g before rebooting and back to LTE after boot). I generally recommend playing with this option, and if you don't need it (e.g. modem doesn't crash on boot), just keep it off - like mentioned before, this is now the default behavior of OpenCS on fresh installs anyway.
(3) This is not finalized or merged upstream is LineageOS yet, but seems like a nice feature to have and test drive already. Some bugs may be possible.
v1.1 (2023-01-08):
Updated to T QPR1 release (LineageOS upstream)
New default camera app (LineageOS upstream) - yes, we cannot change video fps currently (thanks Sony!)
Any other updates by LineageOS upstream
Kernel security updates (also thanks to Flamefire)
Dropped keyprovd service - it is useless on unlocked BL anyway
Show 4G instead of LTE icon - saves some space too
Enable IMS by default - this still only works if carrier is supported
Fix some selinux denials (also thanks to Flamefire)
Fixup ViLTE dependencies - this might in theory work again, but it's not enabled yet
v1.0 (2022-10-02):
Initial release

Can’t wait to try it !!! Thanks tux

Can i flash this using old twrp version like 3.6.2 - 9?

---

The rom is great but every time the device reboots and finishes the boot animation it repeats one more time boot animation.
According to the picture, I can't scroll down as usual, can only use those 4 buttons @@ until rebooting (I had landscape rotation to watch youtube then rotate the screen again when the video ends and it's like that
).
rarely but the sound doesn't play even if i keep the volume high or switch to listening to music or watching youtube until the device is restarted
(sorry if I said wrong or wrong grammar, I'm not very good at English. )

No idea, but for internal memory decription the new one is needed.

What is the use of internal decription if you don't mind me asking

By default android protect (encrypt) your internal memory. TWRP lacked decryption for a long time, now its supported. This means, with new recovery, you can see and manage your internal memory via TWRP using your lockscreen password. Before, you simply can't.

The fingerprint sensor doesn't work, auto brightness is also not working, does anyone know how to fix it

---

Each time I reinstalled a rom, some function which worked just fine on that rom stopped functioning, do you guys know how to prevent this

---

This is a very good ROM. Good for daily use. Didn't encounter any problem. Can't wait for the Pixel Experience Android 13.

I guess you have some missing files or something like that. Try reflashing stock rom and persist.img, something wrong with your files.

Maybe this is a dumb question, but what is the difference between the twrp provided here and the 'stock' twrp from twrp.me? Will both work?

---

Nice room
great work

Both works but this one should be able to decrypt internal memory. No idea if the one from twrp.me does the same or if its the same file.

Hi there,
I'm a complete noob on XDA, but I just flashed this TWRP (twrp-3.6.2_12-0-20221002-poplar) over another TWRP (twrp-3.7.0_9-0-poplar) and now, when entering recovery mode I get stuck in loading screen of teamwin Recovery Project 3.6..2_12-0
I can get out of loading screen by pressing all buttons, and device turns off.
I rebooted into fastboot and flashed back the 3..7 TWRP and now things are back to normal.
Any sugestions on what I can do to install this TWRP?

So, I was able to install lineage-20.0-20221002-UNOFFICIAL-1.0-poplar.zip from this post using TWRP 3.6..2_12-0, without problems.
Did not try to flash twrp-3.7.0_9-0-poplar again.
Is there a thread with future requests? I would like the default browser not to default to google, as the whole point for me is to de-google my phone.

Hi, so I've been absent from Custom Roms for the last couple years - since I got my XZ1 and the DRM key extraction was too much of a hassle for me as I didn't miss much from the stock rom.
Since I got some spare time over the years I was thinking to finally tackle that topic, but I have two questions:
1) The opening post says this
Tux111 said:

Click to expand...
Click to collapse
is it even still relevant for me to back up my DRM keys / back up the TA partition if I don't want to go back to stock? what camera are you using then? is the quality comparable? is slow motion still possible?
2)
i know that in the past, safety net checks were just looking for bootloader / root, but they changed to checking if the ROM is signed with a proper signingkey, right? is this rom signed with a non-test-key?
I've got a couple of banking apps on my phone and it would obviously prevent it from being a daily driver if they were not supported anymore :/
Thanks in advance!

New LOS Update 1.1 is here! Enjoy!

By default the browser isn't Google Chrome afaik, so i don't see the problem. Also, tbh, this makes no sense considering Android=Google. Chromium is builded inside the ROM,is part of the ROM,so once you install Android, you are installing something from Google. So i don't get it.
If you don't install gapps, then you don't have Chrome as default browser. Otherwise, flash gapps and remove Chrome.
