cyanideLROM-ATTGalaxyS2

For those of you looking to run the latest Lollipop OS on your AT&T Galaxy S2 SGH-i777, you may want to check out CyanideL ROM.

Based on latest Android 5.0.2 Lollipop, CyanideL ROM by XDA user Rogersb11 brings a high level of stability and peace of mind for those of you who want to run Android 5.0.

Out of the box, CyanideL ROM brings you almost everything working out of the box including data, WiFi, bluetooth, camera, and more.  The only thing not working is video recording.  Considering everything else working, that’s probably a minor bug and should be fixed in future versions.

Inside CyanideMods in settings, you will be able to supercharge your phone with its endless number of customization including custom system animations, power menu, quick settings, Gesture Anywhere, Density changer, App Circle bar, and much much more.

Although it’s still work in progress, if you want to get the best Lollipop ROM on your SGH-i777, give CyanideL ROM a try this week(end) and do let me know what you think!

    I’ve tried several kernels to get CWM recovery but Samsung recovery is too persisitant. Siyah and AJK kernels failed to hook me up. Do you have any advice at all for me? I’m currently running android 4.0.3 with Siyah 4.3.3 kernel on my i777.
