force firmware reload...

[x-man]

Bit of a newby question but i've never had to do it....how can I force a phone to upgrade its firmware regardless of what is already on. I have a couple of phones that have corrupted firmware and plugging them into my system seems to have got them working again but luckily the site is only a few miles away (my system runs different mcd to theirs.

So I want to make the phone upgrade to the same level of firmware to replace the corrupted one in it.

Hope that makes sense....

Something similar was just brought up in the 5000 thread.

This will erase the Main Load of the phone and download FW again.

Thanks , that didn't work either so i think I may have corrupted files on the 3300, tries to download the files and fails around the 1500 mark everytime. Shouldn't be the phone as I can get them to work fine on my system....

Unless anyone has any further ideas?

Maybe their network...

I had seen something similar on a TW phone.
I had to reduce the size of the TFTP packets.
It took longer to DL the firmware but it worked.

Hi Ralp, is that on the phone? Could you explain where to do this please?

Sarond, its a fairly new network with fibre links we installed, although they would only spring for cheap network switches....maybe i WILL TRY PLUGGING DIRECT INTO THE mITEL TO SEE...

Thanks both

I had a couple phones corrupted the firmware when moving from a 200 to a 3300. Nothing would work to correct this. I put them back on the old 200 let them grab that firmware again, then put them back on the 3300 and they grabbed the correct firmware the second time. I have also had to replace a set that just wouldn't grab the firmware at all.

This turns out to be very similar. Put a couple of really old 5212 on to the switch and they upgraded fine and worked. Brought the 5312's back here to the office and plugged into my system and they upgraded and worked. Took them back to other system and they failed to boot...Interestingly the really old phones upgraded three parts of the flash whilst the newer ones only ever upgraded one part.

I suspect a corrupted part of the flash somewhere on the problem phones. I'll maybe try them on a really old cx we have in the stores and see what happens to them then.

I just ran into a similar issue although it was with some new 5312's being conneted to an older 5000. The phones wouldn't downgrade to their level. Ended up using the extra firware zip file from 4.2 to move them back and after that they were able to further downgrade to what the customer was running

[x-man]

Ok. you have my attention. Extra firmware zip file from 4.2?

these work fine on a 4.2 install but won't downgrade to 4.1.....even though they were working on a 4.1 install....

[johnp]

I think if you look at the software download section on MOL under 4.2 you will see an extra zip file for 5312-5324 phones that had some fixes. I ran that on a local tftp on my laptop to do the downgrade

[johnp]

File name is FW_53XX_4.1.0.24.zip and it was to fix issue with Gig Stand failing after upgrading to ICP3300. I have it here if needed

[x-man]

Got it thanks. Will give it a go.

[johnp]

Certainly not a good thing to go onsite and have a firmware up/down grade fail. My error was related to L2 boot. This was my fix and for sure YMMV. Kind of why I think hosting the tftp during an upgrade is a wise decision when dealing with a lot of sets.

I think I'm having the same issue.  Is there anyway for me to download this firmware:  FW_53XX_4.1.0.24.zip?
Thanks.
