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 12 12.1!
Hi everyone,

Welcome to my thread for i9100 (from 2011) running Android 12. It took a while, but now the rom is at a usable state (no daily).
In my country my provider KPN will stop supporting 3G on march 2022 and this wil make my S2 unusable for daily drive. This means I probably won't port this phone to Android 13 in the future.

Update 16-03-2022
I renamed the thread because I updated the sources to LOS 19.1/Android 12.1 and everything is still working except of GPS.

How to FULL clean flash LOS 19.1 and TWRP 3.6.1_9.0
Warning: This will erase your data-partition completely!

1. Download i9100-LOS 19.1 via ODIN.zip and unzip it on your Windows PC.
2. Start the Odin3 v3.07.exe in the ODIN3 v3.07-folder
3. Choose for PIT: i9100-LOS-19.1.pit
4. Choose for PDA: i9100-LOS-19.1_android-12.1.0_r2.tar
5. Make sure the following checkboxes are checked:
   1. Auto Reboot (optional)
   2. Re-Partition
   3. PDA
6. Click Start!
7. Reboot your phone and LOS 19.1 will start. First start could take about a few minutes.

Note about new PIT-file: The recovery image of TWRP 3.6.1 exceeds the 8mb partition size of our PIT. That is why I introduced a new PIT-file. I also enlarged the System-partition (FACTORYFS) to 2GB. These are the partition changes (compared with stock) of PIT-file i9100-LOS-19.1.pit :

Partition name	Stock size	LOS 19.1 size
RECOVERY	8MB	32MB
CACHE	100MB	76MB
FACTORYFS	512MB	2048MB
DATAFS	2048MB	12792MB
UMS	11784MB	8MB
HIDDEN	512MB	8MB

How to apply Magisk

• 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

Downloads - TWRP 3.6.1
To install TWRP 3.6.1 you need to enlarge your recovery-partition.
You can download manually the PIT file here.
I recommend to use the "full clean flash"-instructions described above which comes with TWRP 3.6.1.

Download TWRP 3.6.1_9.0 here:
twrp-3.6.1_9.0-i9100.img

If you need Toybox instead of Busybox, you can download the toybox-version here:
twrp-3.6.1_9.0-i9100_toybox.img

How to flash .img-file:
In TWRP => Install => Install Image => Choose your img-file => Choose Recovery => Flash

Hello,

nice to find this new Android 12. I come from Los 18. Should I also do the steps with odin, or can I do a factory reset and directly flashing los19?

Best regards Sebastian

You don't need odin coming from los 18. Factory reset and flash los 19 will do.

 

[ran000]

Well done. Work here like shame. The issue - WiFi does not work with Linux(Fedora) WPA hotspot, same as with previous releases
Happy new year!

 

[1victor]

omfg, you are amazing man! happy new year, not downloading right now, cause i am using the galaxy s2 as my main phone, but when i will see an stable-ish build i will install it like i did with los 18.
Hope u will not give up on this phone, even if 3g will no longer be supported in your country, or at least make this port bugless, like android 6 on the galaxy s1

 

[Scorpionea]

wow. never thought that a s2 could run android 12.

Well the same could be said abouth android6,7,8,9,10 and 11 xD

This is simply amazing and astonishing achievement. Props to the Dev !!

yeah true and thanks to the developer, the s2 will be on the latest android version

not really 6, because most 1gb phones/android tablets run android 6, but for 7,8,9,10,11,12 it's amazing.

 

[lee.wp14]

This is so exciting, congrats @rINanDO ! Too bad I'm too busy with college and unable to join the party..
Having majority of the features working even in Android 12, this is just wow, especially the RIL :3

 

[xdalurker1]

You don't need odin coming from los 18. Factory reset and flash los 19 will do.

I moved from LOS 18 with these steps:
1. download and store on sd card the two build files (LOS and magisk)
2. did a full backup via twrp of my LOS 18 phone.
3. Using same twrp as 18 (3.3.1) I installed only LOS 19 on system, and then select image, pick magisk and install as boot.

No wipes were needed, no factory reset, no odin, no repartition and no installation of a new TWRP. For good measure I restored the data as well (was on a different phone, so I got a duplicate to test)


So far can confirm working:


- RIL (Phone/SMS)
- Bluetooth -PC/audio/headset
- Wifi
- IMEI
- Touchkeys
- Display
- Magisk v23.0
- FM Radio (using Spirit2) though I have intermitent problems with audio - not sure who to blame yet

- Camera - Front: works multiple times, no problem but:
- Camera not working when switched to back (selfi) camera get 'can't find device' and then the front stops working as well


Can also confirm my reaction ranging between NO F*CKING WAY to OH MY GOD, IT'S ALIVE!

Happy new year! Already started great with this ROM

Have to admit I'm not surprised to see A12 landing on i9100 since rINanDO was in "silent-mode" for a while.
I suspected that he had been working on this project for some time.
The result, however, is really surprising and far beyond all my expectations... in one word, it's simply A-M-A-Z-I-N-G !!

Thank you rINanDO for your continuous and tireless support for this glorious and nearly immortal device.

I saw that from the end of November TWRP 3.6.0 recovery is also available for our old device but it has a size that exceeds current partition scheme.
So, I edited the PIT file going to double the space for recovery at the expense of some Data partition space.

This allowed me to flash latest TWRP and it all worked like a charm!

 

[althafvly]

10 years old and It's still alive, runs android 12. Great job man @rINanDO
