Delete the LSC certificate or perform factory reset.

I have done factory reset still nothing

How about deleting the ITL cert? Go to Settings -unlock the phone (**#) -> Security --> Trust List --> ITL and delete it.

Shawn,

Doing a factory reset makes it worse. Because you are essentially defaulting the phone firmware to the firmware shipped from factory which I think is 8.3.2....Not all problems are solved by factory reset I learnt the hard way.

To upgrade to the firmware on the 8.5 servers which is 9.X series you need to hop first to 8.5.2. And from there you can jump to 9.X firmwares...

This is discussed in so many threads that you can search.

Must update to firmware 8.5.2 first.

Only after, you can update to any further firmware release.

Shawn,

As Paolo mentioned, the phone firmware MUST be upgraded to 8.5.2 first before going to 9.1.1 SR1. This is clearly mentioned in the release notes for firmware version 9.1.1 SR1

" For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(2)SR1 or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 9.1(1)SR1 or later. "

Therefore, it is always a best practice to read through the release notes guide of desired firmware version to avoid such issues. link to Release notes is always present on CCO page from where the firmware can be downloaded.

Hope it helps ?

I don't believe factory reset downgrades firmware, it simply erases all configuration, certs, etc.
