Hello,

We have 2 Simatic Field PG M5's for our team.

I upgraded the Bios for one of them and it was successful. For the second one I tried the upgrade from BIOS_V22.01.01 to  BIOS_V22.01.03, but it was failed. During the upgrade process, -after I approved the upgrade process- machine froze, screen faded out and it shut down itself. To make sure, I have waited for couple minutes and then open it up. It opened, I also checked the bios version is the new bios version. But when the machine start I realized there is an error appeared for couple seconds. It says : "Error - Intel ME - Please contact customer support".

I also tried to upgrade it again. This time It can be able to do upgrading steps, at least I could be able to see the steps this time, but when it came to the INTEL ME part, Flash status stuck with 50% and it gave an error like "Upgrade failed!"

Now I still can see the error "Error - Intel ME - Please contact customer support" at every opening.

Is there any method to turn BIOS back to the factory settings, or anything to correct this problem?

Could you please help me about it?
