About LineageOS
LineageOS is a free and open-source operating system for set-top boxes, smartphones and tablet computers, based on the Android mobile platform. It is the successor to the custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.
LineageOS was officially launched on December 24, 2016, with the source code available on GitHub. Since that time, LineageOS development builds now cover more than 185 phone models with over 1.9 million active installs,having doubled its user base in the month February–March 2017 And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
About Galaxy S2 running Android 13.0!
Hi everyone,
Welcome to my thread for i9100 (2011) running Android 13! Currently I'm not using my S2 as daily drive anymore since 3G is turned off. I used the phone primary for calling and WhatsApp but without 3G this isn't working for me. But nevertheless it didn't stopped me for porting Android 13 on this legendary phone.
Most of the work has been done by "LineageOS Ultra Legacy"-team. I don't know if this is the right teamname but someone added me in the Telegram group and they gave me some hints during development. Thanks guys! I was quite late starting porting this ROM and I was happy most BPF issues were already solved there. The i9100's kernel (still 3.0.101) needed some patches related to random=syscall and bpf in order to boot Android at all. That took a while to get it stable passing the factory i9100 splashscreen. From that point I could build LineageOS with the sources of "LineageOS Ultra Legacy"-team.

How to install LineageOS 20.0
If you are familiar with the installation of custom ROMs than you probably already know what to do.
If you already have Lineage 19.1 running, just do a full clean install in TWRP and your good to go.
I personally still use the old TWRP 3.3.1-1 because TWRP 3.6.1 fails to make the Magisk enabled kernel file I create seperatly for every release.
For now please look for detailed instructions here to get LineageOS 19.1 running first.
How to apply Magisk-kernel on top of LineageOS 20.0
Normally you flash the Magisk.zip or install it with using the MagiskManager app. But our device is ancient and uses a deprecated partition/boot procedure. Magisk needs to update the ramdisk-image but that is integrated into the kernel-image (zImage). Therefore I created this seperate kernel-image (zImage-file) with the Magisk modified ramdisk-image.
Copy the Magisked kernel on the SD-card of your phone.
This is the second download-file in the download section ending with ...magisk_boot.img.
Reboot into recovery (TWRP)
In TWRP
Choose Install
Choose Install Image
Now you can select ...magisk_boot.img
Choose Boot
And flash it
Reboot into Android
Download Magisk from https://magiskmanager.com
If you download the .zip, rename it to .apk
Install the Magisk App in Android and follow its instructions

Wow, thank you for the hard work! Didn't expect to see android 13 on the s2, so this was a pleasant surprise, gonna keep me awake tonight. I got a second galaxy s2 a few days ago, so I will definitely try this out.
Unfortunately, it appears that the provided download of the rom is corrupted, attempting to flash it on the phone returns a ''zip file is corrupt error'' and on further inspection most files are missing from the zip compared to lineage os 19.1, 7zip also reports that the archive is corrupted while trying to extract it. I already tried downloading it three times just to be certain, no avail.
Maybe something is up with AFH, initially it says 506.2MB, then starts downloading 131MB?

I'm only getting 131MB out of 506MB of the zip file as well on Android File Host.
Also, congrats rlNanDo for keeping development alive for the i9100! I'm glad I have this phone just to see what's possible.

I see! Hmm that's strange. I'll try uploading it again.
Edit: It succeeds uploading, but when downloading it is still a portion of the actual file size of 506MB.... I will try uploading later the day.

---

Unbelievable.. I still can't upload. It now fails instead of a faulty success message after upload. Has anyone an idea to host roms besides androidfilehost?

Home - MEGA
Secure and private cloud storage for everyone. Store and share files, chat, meet, back up, sync, and more.
mega.io
maybe....

Thank you for long life famous subj.
Work well here.
Please, look at possibility to upload both installation files to Mega. Could not get androidfilehost since your announcement.

---

Just installed it on my S2! Seems to be running alright so far. Here are some bugs I'm facing right now.
Text is small in the launcher (and very slightly so in Settings?)
Brightness does not work
Bluetooth does not connect to headset (Pixel Buds A)
Cameras do not work
Getting random crashes during usage
Small dot in lock screen when password is not set, around the same location as a lock would be when a password is set
No ambient display settings
Camera preview is wide until first picture is taken
I'll update this list as I spot things on Build #1.
Awesome that Android 13 even runs on this thing! Amazing job to the whole team that brought this to life!
If this list seems critical, I really don't mean it that way. I just want to try help spot bugs

I think its very smooth , but I think button navigation is better because pressing Home button brings a reboot of the device , on buttons its just fine,.

Has no university nominated you for an honoris causa doctor?
This is a huge omission. We need to do something about it.
