Hi Jonas,
Thanks for your respond and Luckyly i was able to fix the whole system and have Full-functionallity!
I did format a USB stick with the USB-image as download from the Juniper-support-website.
On the device, Under; boot-options I was able to select USB-Boot and out of nothing, the system recognized all what was needed and executed the bootload from USB.
It booted one more time and came back 100% and I was able to access the Junos CLI.
Actually, a pretty forward recvovery!
All you need is a USB-image from the Juniper-Support-Download section.
Make a bootable USB-image with 3th part software.
- I used: Win32Diskmager.
Boot from this USB and sit, wait and smile
Best regards,
ARE
