You don't using nAa kernel right? To use Mini-cm7 2.2.0 you must use naa kernel

Like Elwino2.3 said you need to flash the nAa kernel using flashtool.
But before that you need to unlock your bootloader than flash the kernel.
Please re-read the thread carefully where you got the MiniCm7-2.2.0 ROM.
All necessary details are provided.
Don't worry it also happened to me. I got too confident coz i had flashed many other ROM's and so i just flashed the ROM without reading the instruction.
You either use Sony Ericsson Update Service to reset your phone back to the stock sony ericsson rom or you can try to directly flash the kernel.
As for myself i used the Update Service coz i thought that it was more safe.
