DM800 boot freeze on dream multimedia

[teb]

I have installed a new image to my flash using dreamup. Now my DB won't boot it freezes on dreammultimedia logo. I have red posts from others with the same problem but i can't find a good solution. Something with a bootloader r72?
I have tried to reflash it with other images but nothing works.
Can anyone help me with this?
