Cisco 2911XM router not booting

[ohforce55]

I'm currently trying to upgrade IOS on a 2911 router.

It seems like there is no any IOS for 2911 these days on the Internet...

rommon 1 > dir flash:
           File size                                Checksum              File name
3466848 bytes (0x34e660)                 0x008a                ns50ns25.5.0.0r6.0

The problem I'm having now is that the router's image was deleted and there is no any backup (no image, no IOS)..

What should I do since I don't have any backup IOS and image.... I'm not even sure what ns50ns25.5.0.0r6.0 is and how it is installed..

Also, there is no any config on the router (no interface configured) so the tftp way won't be helpful.

Please help me..

1. I tried to change boot system (0,2, and 15). None of them worked.

2. Tried 0x2142 but it doesn't work

rommon 1 > confreg 0x2142

You must reset or power cycle for new config to take effect
rommon 2 > reset

You meant 2611 instead of 2911, right?

Anyway, that file seems to belong to the Juniper NetScreen-25:

You could try to recover your router either by "copy xmodem: flash:", or by TFTP-booting it from ROMMON:

(If I remember correctly, you need to use the first Ethernet port on the router for that;  unfortunately, the documents linked at the end of that page seem to be nowhere to be found anymore.)

Although it's a very old (and unsupported) platform, IOS repositories can still be googled online - this one for example:

Thank you for your reply!

I found another way using xmodem without tftp server.

I really appreciate for the link.
