Mitel 6863i SIP - uunable to update firmware

[Haxx]

Hi all! Thank you for this wonderful forum....
I have a phone here that I'm unable to update to newer firmware and seeking help.
I have tried multiple firmwares, both in web using TFTP and web recover using HTTP, but firmware will not update.... Last firmware I tried was: 4.2.0.2023.SP2 - 6863i.st

What am I doing wrong??

I managed to upgrade to 4.0.0.2031 .. will try 4.1...

Initial I tried 4.0 -> 4.1 without 4.0.0.2031

Software 4.1 failed also..

Web Recovery is the last ditch attempt I know of. But you are saying even that fails?

What error do you see?

HI and thank you for the answer... there is no error.  The HW simply won't update, it appears as it accepts it and there is no error... it's like it accepts the FW and process to FW update and then reboot but after reboot it's back on the original FW... I have multiple 6863i here and I tried a few and all of them fails to update to new SW :S
Do I have upgrade for each release??

If someone could share FW 4.1.0.128 for 6863i that would be great!
