Problem: Barry Allen 6.2.x and official firmware in flash

I have the official firmware 3.2.1a in my flash and i am trying to install Barry Allen 6.2.7. I upgraded my bootloader to 86, installed kernel-module-loop but i keep getting the message:
=================================================================dm7020hd
=================================================================
checking kernel for loop device driver ...
Sorry, kernel in Flash has no loop device driver
=================================================================preinst script returned status 1
Collected errors:
* Aborting installation of enigma2-plugin-extensions-barryallen
* Cannot find package enigma2-plugin-extensions-barryallen.

Any ideas on what i m doing wrong?
