Default [Q] My atrix freeze on Motorola logo

Hi.

I installed sbp, unlocked bootloader and installed ClockworkMod successfully.

I also did nandroid backup.

I tried to install two different ROMs and restore the backup nandroid and my phone is frozen on the screen with the logo of motorola.

When I go to install any of the ROMs, the following messages are displayed:

Code:
-- Installing: /sdcard/xxxxx.zip
Finding update package ...
Opening update package ...
Installing update ...

Install from sdcard complete.
xxxxx is the rom I'm trying to install.

What should I do?

The provider of my phone here in Brazil is Tim.

Thank you.
