Unable to log into web interface 3Com 4500 Switch

I had a 3Com 4500 switch I was unable to log into the web interface.  Not being familiar with the cli for this device I was at a bit of a disadvantage. Having done a full factory reset I was still unable to access the web interface.  I had a second unit the same steps were performed on which worked just fine. I noticed the firmware was at a 2006 version so I decided the first step would be to do a firmware update.  I was able to get the required files from the HP site as new as 2012.  I downloaded the files, setup my tftp server.  I use http://tftpd32.jounin.net/ which works really well. And wend forward.  I noticed when I did a dir listing of the device it was missing one of the bootrom files. I updated the files, set the boot options and restarted the device. Still unable to log into web interface, after some google fu I found the procedure to reset web access to the device.

Upgrade process:
first get a list of files:
<4500>dir
Directory of unit1>flash:/
0 -rw- 5195 Feb 04 2007 13:21:21 3comoscfg.def
1 -rw- 642479 Feb 04 2007 13:21:52 s3p02_01.web
2 -rw- 4088266 Feb 04 2007 13:24:15 s3n03_02_00s56.app
3 -rw- 1364 Apr 02 2000 00:47:45 3comoscfg.cfg

Next delete the files an clear recycle bin(there is not enough flash space to store both sets, make sure you have backups)
<4500>delete s3p02_01.web
<4500>delete s3n03_02_00s56.app
<4500>reset recycle-bin
Clear flash:/3comoscfg.cfg ?[Y/N]:y
Clearing files from flash may take a long time. Please wait…
