HyDrOG3NICS: CM9 + AOKP Based ROM for Galaxy S2

Advertisement

What happens when two great custom ROMs come together as one? Well, now you can find out with HyDrOG3NICS ROM, an Ice Cream Sandwich Android 4.0.3 based ROM for the Galaxy S2 i9100 which combines two AOSP ROMs namely AOKP and CM9 (CyanogenMod), giving you the strong and trusted base of CM9, coupled with the amazing customization and mods found in AOKP ROM.

Do keep in mind that the ROM is still in development stage, as CM9 and AOKP themselves are currently under development, so expect the same bugs and issues found in CM9 and AOKP to be present here as well.

Compatibility

This procedure is compatible only and only with Samsung Galaxy S2, model number i9100. It’s not compatible with any other device. Check your device’s model number in: Settings » About phone.

    Installed 2 days ago and was favorably impressed with how smooth the installation especially how quick the Titanium Backup installed my Apps and data. This is an exceptionally stable build and tests better than my Galaxy Note running AOKP also.
