Catalyst 3650 Rommon flash Read only

[cleetusant]

Hello

My Catalyst WS-3650-48TS switch shows read only flash file system.

After IOS upgrade, switch went to rommon mode.

While trying to boot from USB, it shows not enough memory for Full image.

I tried to delete some files and make room for booting. Switch doesn't allow me to delete files from flash.

Please guide to fix it.

Below given the output of various command I used.

Hi there,

Have tried to recover the old installation? It looks like you were previously running in INSTALL mode. From ROMMON can you issue the command

boot flash:packages.conf

...see it this will allow IOS-XE to load. You can then attempt your upgrade again.

cheers,

Seb.

I'm having the same problem. But when I boot from flash:packages.conf, the IOS-XE loads but then keeps restarting. Here is the complete message from boot to restart, link. Any help will be appreciated, thank you.
