You have probably flashed a 520 image instead of the 7080 image. You now need a MiniUSB cable to get the box working again. For instructions see: DM820 not booting
Hi I ve installed newnigma to my box ,and since wont boot and no option to go to rescue mode for installing different firmware.I ve tried "vmlinuz-rescue--3.4-r0.51-dm7080-20160405.bin" to get it running but with no results.. In telnet it shows me dm520 for some reason..but the box itself is 7080.Please help to find a solution:) Thanks
