I am trying to upgrade the IOS on cisco 3825 from 124-9.T1.bin to 124.24.t6.bin, after I upload the configuration to the CF and verify the file,
everything appears fine but when I try to load the new image it fails with following error and falls back to old image :-
System Bootstrap, version 12.3(11r)T2, RELEASE SOFTWARE (fc1)
Readonly ROMMON intialized
boot: cannot open "flash:"
an alternate boot helper program is not specified
(monitor variable "BOOTLDR" is not set)
and unable to determine first file in bootflash
loadprog: error - on file open
boot: cannot load "c3825-advsecurityk9-mz.124-24.T6.bin"
Then after few minutes it boot to the Old 12(4).9 ios again.
Please help !
Ok, try upgrading the Bootstrap and then try the new IOS.
Grrrrr ... I can't even read the Release Notes for this version of IOS: Forbidden File or Application
To my best knowledge, the MD5 sum is not stored in the IOS image file itself. The verify /md5 will simply produce an MD5 hash but it cannot tell you if it is correct or not - you have to go to the CCO and verify it for yourself. The verify /md5 has no reference information to compare the computed value to.
