flash back to stock (with sony companion,recover phone)
root
cmw recovery
wipe
flash CM7 (I did miniCM7)
turn off the device (take battery out) (the device can't boot normal)
open flashtool and press the lightning icon
chose nAa-11
press ok
connect device with USB
press back button and insert battery fast
reboot (if not boot take out battery and try again)

kernel: http://forum.xda-developers.com/show....php?t=1415012 WARNING only for pro mini. for other device please read the thread.

If you flash the kernel first, you save yourself an awful lot of trouble messing with your battery and things, just flash the kernel with flashtool, boot into recovery and install the rom from sdcard.
