Problem of starting of my Dreambox 800Se

Hello
I have just bought a new DBox 800Se.
It went very well at the beginning.
I then installed the image BHOLE (Backup flash) which went very well.
But I recently had to extinguish the box and by relighting it it stopped with starting with the stringcourse color which stopped with the whole beginning.
I tested several solutions but without result of which the reinstalment of the image by LAN and port series (micro usb). ¶I also reinstalled the boot with Non Ca Found but always without result.
Somebody could it help me please.

Thank you in advance

Initially thank you with all to have answered me.

the version of the image that I used is "FlashBackup-dm800se-2013-05-06@20.17.47-sim2-SSL-84B".
I do not know if it is a verson Poenix.
In addition it well currently goes on old DMbox SE Why?
I installed an image GP3 which goes very well.
but I prefer the BH. ¶

Thank you
