DM920 UHD Blocked in Rescue mode

Hi all,

My DM920 was working well when, suddenly, showed the fixed red led (rescue mode).

I don’t know why.

I have tried to connect to it via browser "http// 192.168.1.xx" but the following message appears on the screen on my PC:

"Content-Type: text/html;charset=utf-8"

I have also tried with putty to enter the following command : echo "rescue" >> /proc/stb/fp/boot_mode

But the result was "-bash: can't create /proc/stb/fp/boot_mode: nonexistent directory".

Is there anybody who could help me?

Many thanks

I's a link to a page at jb8a8f8.com related to this issue.

Reason why this happens, and why it can be repaired without the display or front panel connected is unknown, but it seems to be related by using openpli however it is just a thought.
