It would be safe to firstly flash original 2.03 UEFI, if in normal working mode 11.0.0.1339 would appear then for me it is enough, if 10.8.0.1303 then there's a reason to update OROM.

This time I will not be the first one to try this beta, in 2.03 there's some info that "After flashing this version please flash newer versions only!" so getting back to L1.30 and older could not be possible due to MEI update.

Hexedited 8086,1502 string suggests that something might have changed in hardware booting procedure, my LSI card is demanding enough in that matter, if something is not broken then it's not needed to repair...

Awaiting for some beta-testers replies
