UNABLE TO LOAD iOS ON CATAYST 3650

[Jesutofunmi O]

Hello, 

Please, I need help with loading an iOS image on a Catalyst 3650 switch with missing boot image. 

1. I have tried to boot from USB: it seems as if it's going through but eventually fails. It just keeps going through a tiring reboot loop process.

2. I have tied to copy .bin file into flash which also fails. 

3. I have tried copying file to flash using xmodem. This fails too. Returns the error "read only file system".

I am guessing all these issues I am having is because the flash memory is in read-only format. How can I fix this please? Please see screenshot. 

Expecting feedback. 

Thanks!

Hello Leo,

Thanks for responding. 

I tried emergency-install too, it first starts as if it's loading but ends up with the same reboot loop. I have tried 3 different iOS images. Please see attached screenshot.

Is that all?  After Launching Kernel Flags nothing happens?  

[Jesutofunmi O]

Nope, it runs its course but nothing happens after. Just reboots again and again and again. 

I suspect the flash memory being in a read-only format is why I am unable to write anything to it. I have tried using "set_bs" to change it to 'read-write' but still remains the same even after reboot. See screenshot and full error before the reboot occurs.

Contact Cisco TAC and organize for an RMA.  This could be CSCva30394.
