Evo Xfinity problem!

Hello,
Could anyone please guide me how to install both android and enigma 2 on evo xfinity.I tried and tried many times without luck.I put together update.zip (android fw) and unpacked enigma 2 (those 6 files) in usb stick and I switch off receiver,hold the vol- key,turn on receiver,it comes up to recovery,i press the update from sdcard and it goes well but after restarting I have only android fw and no e2. I press the vol+ to boot e2 but the logo on the tv keeps staying all the time,when I restart receiver i just leave it to boot without pressing any gumb it goes straight to android sw.
P.S. I installed multiboot loader.
