Looking for an alternate ROM for your Optimus Black – well what better than CyanogenMod itself. It is not ready for daily use right now but development is on in full swing. There are bugs right now but so don’t install it if you use Optimus Black as your main device.
You will need root access and CWM recovery to install the current build of CyanogenMOD for Optimus Black. Download & more info about installation at Rootzwiki.
LG Optimus Black is a nice device and great display and a pretty decent pricing, so your hate towards LG’s not so UI is making you stop from buying the device- time to think again.
