I'll no longer update this project, my focus is now at CyanogenMod 13 (CM13 thread link)​​Samsung Galaxy SII​CyanogenMod 12.1​CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for CyanogenMod is available in the CyanogenMod Github Repo.
Code:

[size=+1]Q. What recovery does this ROM support?[/size]

[size=+1]Q. Which GAPPS package should i install?[/size]
A. You can install "NANO GAPPS" if you haven't re-partitioned your system OR you have stock System Partition size.
[size=+1]Q. How much System Partition size is needed to flash this ROM?[/size]
A. you can flash this ROM on your stock system partition but it is recommended to have 1GB System Partition as ART runtime requires more space. also, it's advisable to have more space on system partition if you would like to install standard GAPPS package.
[size=+1]Q. How can I increase System Partition space?[/size]
A.

Good job. I want to test it but I need to know first what the recovery required to flash it, the gapps. I'll wait til u update the OP for more information. Thanks for bringing lollipop for our S2. Your hard work deserves to be rewarded.

I'm pretty sure that CM don't have a theme engine on 5.0, also, you don't want to apply a theme on a unstable rom.

As stated on OP you need a Kitkat Compatible CWM recovery to flash it (6.0.4.5+)
Updated OP with gapps ( I did not test the ROM with gapps )

WIP!
Guys, I beg you not to litter thread useless messages. This thread is needed for the developers!

---

I will test as soon as I can, thanks dude

Have downloaded and installed this rom.
General function is smooth but was unable to install Gapps provided due to no storage space after install (have had this with all stock Gapps from Kit Kat too). We might need a nano build for 5.0 Gapps.
Random reboots from lock screen after graphical glitches. If the screen if left on it will stay on fine with no reboots till the screen turns off. Then reboot.
Dialer and call works works but only on speaker. Apps crashing (browser, keyboard etc).
Will have a play around with some settings and apps and report back.
Edit: After a bit more playing with the build, I installed Google Keyboard and got the keyboard working. WiFi does work, when chrome is installed that does work.
Reboots and graphic glitches have stopped but messaging app does not work, it will crash while trying to send, when I reboot it will send old messages and receive new ones (I think as it sent to myself when I tested).
Will try again with Hangouts when I can get it working but need a Gapps package to work on it first.
Any ideas?

---

Are sources available anywhere?

---

In addition, bluetooth, camera does not work, dialler hangs massively, few graphic glitches, browser force closes...

---

i will not try it now but im here to tell you you are the best man because you still think about our device :good:

---

guys i have installed it on my s2. i will post some screens later but i need someone to tell me how to install cwm or twrp so i can go back to my previous rom?

---

can we get official support now ?

---

WIP!
