ERROR 1802 - Unauthorized Network Card - T410

This error occured after a recent Windows Update which included a BIOS upgrade for the Lenovo ThinkPad T410.  This laptop was purchased as a refurbished unit from MicroCenter in Atlanta, GA in 2015 and up to this point, no changes have been made to the  "miniPCI Network Card" referenced in the error message.  I'm unable to boot from CD/DVD to upgrade using the ISO file suggested by the Lenovo Knowledge Base.

Re: ERROR 1802 - Unauthorized Network Card - T410

Welcome to the Community

Do you remember the previouse version of the BIOS, before upgrade? Any cnance it was patched by some one? Is there a BIOS backup file in the folder with extracted recent BIOS update package? Are there the symbols, two groups of 4 symbols via slash, in the string with error 1802? If the latter are missing, could you provide the wwan card label image?
