Installing HyDrOG3NICS custom ROM on Samsung Galaxy S2 GT-I9100
The Samsung Galaxy S2 is a popular choice for many users all over the world, and when it comes to custom ROMs, the device is certainly not left far behind. What do you get when you have two great custom ROMs and mash them together? The result is the astonishing HyDrOG3NICS ROM.
The HyDrOG3NICS ROM combines two AOSP-based ROMs, namely AOKP (Android Open Kang Project) and CyanogenMod 9, giving users a rock-stable CyanogenMod 9 build with the visual and performance customizations found in AOKP ROMs.
Take note that the HyDrOG3NICS ROM is still in its beta stages as both CM9 and AOKP are currently under heavy development. Expect to see bugs and disabled features found in CM9 and AOKP ROMs to be also present in the HyDrOG3NICS ROM.
Among the known issues in HyDrOG3NICS are the following:
- Storage: MTP File Transfer partially broken (USB Sharing)
- Storage: Media Scanner makes CPU going crazy, device gets hot, battery goes down
- Camera: video recording doesn’t store recorded videos
- Camera: crashes when using face effects
- FM Radio: not implemented
- TV Out: not working yet
