5.05 to 6.72 upgrade without bluray : error su-42118-6

Hi

I m getting error su-42118-6 when trying to upgrade from 5.05 to 6.72 on a unit with a broken bluray reader.

Is there any talk or dev regarding a similar method with a special pkg when upgrading from 4.74 to 5.05.

Is it even possible in this case ?

Tx
