Warranty shouldn't be valid. (of course depends seller roles)
I can't fully understand your explanation but please follow SPFT updating procedure from here

And here you have all available ROMs

I presume that your phone came with older ROM version cause such issues with updating.

Of course if phone won't switch on please connect charger and wait until is fully charged.
