Sounds like you bricked it(you are screwed), you also have a massive red review..
Everyone assumes you are just stirring shit up. Sounds like you know that losing power during a firmware update is bad news(it is for any Fing device) and you are just trying to stir up some trouble.
My thoughts exactly... but let's be the better bunch

That said, to OP...
Anything going wrong during a firmware update (why???) results 99% of the time in hardware damage, you need a new card.
Usually, Bitmain will tell you it's the LAST thing ANYONE should do, even pros don't get it right all the time.
I never did any firmware updates and never missed a second of mining; I like to plan a lot.
It's like losing power during a .NET install/update or if something goes bad during a system restore.
Your hashboards still work, probably... but you will need a new ethernet control card, which makes no sense to buy anything for S1's anymore.
Those suckers are around $50 a pop, you can get a new S1 at that price.
Good luck to ya
Send that miner to your decom pile and keep it for parts.
