Stuck in Recovery & can't start any ROM topic

Hi!

I just HTCdev unlocked the bootloader and rooted the HTC Desire HD and everything was fine. I was in the stock ROM rooted, so I flashed the recovery and then I tried to install some ROMs and everything failed, I was stucked in the HTC loading screen...

I tried to flash several ROMs but the result was always the same: stuck in the loading screen. I did a full wipe everytime of course, but it didn´t solve anything.

At the end I tried to flash this:
[ROM][DEC 8] Official RUU_Ace_Sense30_S_HTC_WWE_3.12.405.1 STOCK ROOTED
http://forum.xda-developers.com/show....php?t=1382235

And it worked!

But if I tried to flash another ROM like SlimBean but again, stucked...

Any ideas what I'm doing wrong?

Thanks!
