I have a number of 2960 LAN Lite switches running image C2960-lanlitek9-mz.122-50.se5.bin. I was asked to upgrade these to C2960-lanlitek9-mz.122-58.SE1.bin. I down loaded the image via TFTP and this resulted in flash looking as shown below
Directory of flash:/

The trouble is that when I try to reload the switch it hangs output from console shown below
done.

Looks like there is something wrong with the new image however:-
I booted the switch into Boot loader and tried to boot from the original image again the switch hung.
I tried to delete the new image the switch hung
I treid to format the flash the switch hung
It seems that after booting the switch into Boot Loader and using Flash_init I can see the directory of flash above but can do nothing else making the switch hang.
This has happened on two switches I have tried to upgrade
The funny thing is that I have two other C2960 LAN Lite which have upgraded sucessfully with the same flash config.
Two questions
1 Has any one had the same problem?
2 How do you format or clear the flash when Bootloader keeps hanging when delete and format are used in Boot Loader ?
