help with 3825 upgrade to 12.4(24).t6 !!!

Answered Question
Sep 20th, 2011

Hello everyone,

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 !

Thanks

Manish

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

Manish,

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.

Best regards,

Peter

Manish,

This is strange... What puzzles me is that the router is finally able to boot the old IOS. I have seen CF cards being corrupt but in that case, the router was not able to boot at all.

My suggestion is to format your CF card directly in the router using the format flash: command, and subsequently, using the usual copy command to store the new IOS into it. Try avoiding a PC with CF card reader to store the IOS. Although it should work, there may be some caveats so let's avoid them for now.

By the way, have you used any boot system command?

Best regards,

Peter

Hi Peter,

Thanks for replying, yes I did use couple commands for boot system :-

1> no boot system

2> boot system flash c-3825-xxxxx-124.24.t6.bin

3> wr

but its getting stuck at that BOOTLDR error and then goes to OLD ios or goes in ROMMON mode  from where I have to force it boot into old IOS as it would work with new IOS.

Do you think I have to upgrade boot image, cuz i remeber upgrading 7204 ones with a Cisco TAC and he used some Bootldr command. Wish I would have paid attention to it then .

Manish,

Hmmm... And when you are in the ROMMON, what would be the effect of using the following command?

boot flash:c3825-xxx-124-24.T6.bin

Please correct the syntax if necessary, these boot commands sometimes require the use of the "flash:" filesystem designator, sometimes they do not.

Also please observe the suggestions provided by Leo. If you manage to boot at least the old IOS, verify the MD5 sum of the new IOS using the verify /md5 flash:c3825-xxx-124-24.T6.bin command and compare it to the MD5 sum available at the CCO.

Best regards,

Peter

I can't answer for the rest but I always upgrade the bootstrap whenever I have the chance.

I learnt my lesson the hard way when I was upgrading the memory of a 3745 without upgrading the bootstrap first.  I wasted 2 days cursing until someone pointed out a piece of paper that came with the memory.  Duhhhhhhh ...

Leo Laohoo Tue, 09/20/2011 - 16:01

Have you compared the MD5 hash values?  I see this when the file download is not "complete".

System Bootstrap, version 12.3(11r)T2, RELEASE SOFTWARE (fc1)

One more thing:  Since you are going to reboot the router anyway, upgrade your bootstrap.  IT's kinda-bit old.

Upgrade to 12.3(13r)T15.

Hi Leo,

Can you please point me to right Guide for upgrading the Bootstrap ?  I am not sure about which is the correct documentation to follow.

Thanks

Manish

BTW the MD5 checksum is correct, it checked it with verify command. it doesnt complain about that.

Upgraded the Bootstrap but a it still doesn't support new IOS but also shows following in the Sh Version :-

"System returned to ROM by watchdog timer expired" which points to Hardware issue I think.

any suggestions, don't have smartnet on this one.

Pull apart your router (remove all modules) and pop the lid.  Take the DRAM out and wipe it with a non-static cloth.  You can also "go-into-town" with a can of compressed air at the DRAM slot too.

Thanks Leo & Peter ! It was bad CF, the bootstrap helped too ....

Thanks Again

Glad to see it's working Manish.  Forgot about the "CF" factor in the equation.  Should've thought about that.

And thanks for the rating.

Leo Laohoo Tue, 09/20/2011 - 16:18

Hi Manish,

No guide needed.  The command is very simple:   upgrade rom file tftp:///filename.bin

ROMmon file found HERE.

By the way, bootstrap version 12.4(13r)T and higher will allow you to boot from USB.  Nifty, huh?
