I can make another build which will be more stable! :)
porting JB+ ROMs is very hard and it mostly causes into bootloop.
I've just flashed in for my Wildfire, and it reboots automatically in every 1-4 minutes. I was using this CM10 based ROM...
Unfortunately, I bought it too early, in August 2012, and it was cost 40 €, and it is the 256 MB model B... I'm so unhappy.
