The Galaxy Tab 8.9 was one of Samsung’s flagship Honeycomb devices, but with the latest focus being on Galaxy Tab 2 and Galaxy Note 10.1, the device seems to have fallen out of favor in Sammy’s court. Not so here at XDA, though. Fortunately for the owners of the device, XDA Senior Member C-o-M has ported the latest Android 4.2.1 to the tablet in form of an unofficial CyanogenMod 10.1 nightly ROM.
Do note that this is an experimental build. Several core features such as WiFi, Bluetooth, sound, cameras, display, storage and rotation sensors work, but everything else is pretty much untested. Don’t fret, though. The ROM is a work-in-progress, and we should hopefully start seeing updates soon to fix these problems, and make it suitable enough for a daily driver.
Head over to the forum thread to give it a try for yourself._________
