Try cmos reset on the back of your motherboard.Also were there power went out when you did the update?If you have no problem with your motherboard then you must not update it at least i not recommend to do it.Also try to ask msi what to do they will hopefully get to you.From there maybe you can get something.And probably know where to go next.

I want to update it because my back panel USB ports stoped working for some reason. I don't have reset button, even 2 pins on motherboard called CMOS, CLR_CMOS, PASSWORD or anything like this. But i do have jumper and its set on 2 of 3 pins called JUSB_PW2.
I aslo have JBAT1 like in manual (page 24)[www.manualslib.com] but this isnt working.

CMOS reset is done either by removing CR2032 battery for a few seconds or using the jumper setttings as provided by motherboard manufacturer.

some motherboard manufacturers have dual bios such that if one bios is incorrectly loaded/flashed, then the pther one can still function.

how did you flash bios for msi h81-p33?
