(a7) me fw downgrade - request mespilock failed error after "microsoft update" bios update for dell


I normally install bios from dell update, but later a new bios update appeared in microsoft windows update and I apply it. after that this error happened and now my intel vpro is not working so I cant open my system remotely over vpn. probably windows try to install a previous bios over a newer bios.

My hardware is dell precision 5820, My bios is now v2.31 but intel me(AMT) is not in the same version as 2.31 and wont updateand doesnt work either.

my cpu is intel w-2145 and it was working in old days. 

hwinfo64 says intel amt not supported I try to apply latest fimware from dell, everything except intel ME is updated.  but intel me firmware is not updating. it is locked in version and also dont work either.

I asked this question in dell forums but no one is experinced enough to give me an answer. (0 answers)

I am proficient in computing bu couldn't solve the mistery.


Thank you, any help is appreciated.

Sorry, but this is not an Intel problem.  You need to work the dell bios proble out with---- DELL!

Next time, do not let Microsoft install any firmware.
