IBM Power 740 won't boot after firmware update

A team member installed the wrong version of License Code on a Power 740 system used in our Development environment.

The system will no longer boot.

Does anyone have IBM documentation or experience to share on recovering a system that currently reports "Unsupported License Code version detected" on boot-up?

We plan to contact IBM Support if no one has run into this before.

Thanks,
Kevin Dailey

Did he install on temp or permanent side. If on temp you should be able to boot from the permanent side (old firmware).

It has been ages since I have updated firmware without an active partition to update from. Although I believe the preferred method now would be to try and use an HMC to update the system.

What 4 or 8 letter code does the panel show when you power on the system (also check the ASMI interface for the history of the codes).
