[SOLVED] Recover bricked HPE 5820 router? Application program does not exist.


I accidentally bricked my 5820 JG219A. I sucessfully upgraded the firmware to A5800_5820X-CMW520-R1810P13. Thinking it is upgrded so I don't need the bin files anymore, I deleted the A5800_5820X-CMW520-R1810P13.bin on the flash.

Guess only noobs do that.

Now router goes to boot menu, saying the is no application file.

I can only get XModem to work.

FTP doesnt connect, Laptop to Switch with Serial & Lan cable:
5820: Server: local: gateway:,
Laptop to port 25:,, gateway blank.

Xmodem set to 9600, 8, N, 1, N, switching to 115200 when loading the file.

I have tried to:

1. Download application file A5800_5820X-CMW520-R1810P13.bin to flash - fails. file not visible in file system. pressing 2 to see application says there is none.

6. Upgrade Full BootRom with A5800_5820X-CMW520-R1810P13.bin - fails

CRTL-R Load application to SDRAM - loads, says invalid file.

Any suggestions how to recover the switch ? I have the config file saved. So happy to do what is needed.



So it turned out that loading with Option 1. Download to flash actually works using XModem but you have to be there when the download finished (takes ~65 minutes) to enter the comands to actually load it. If you are not there, I did it overnight, it times out and fails.
