[Q] Bricked? topic

Hello . Today i wanted to upgrade my Nexus With Paranoid 4beta4 .
my situatios it's this :) :
I downloaded the costum rom on my other leptop and i downloaded gapps too
I tried to sideload them and somehow managed to do it .. i say somehow becouse i had lot's of problem at drivers instalation
after i transfered the files i erased everithing on my Gnex so i can get a new clean OS (not smart i know)
and after i realized i tried to sideload the Os at least. didn't work at all .. My fastboot .. (the max where i ca get my Gnex in question right now ) gives this error "device not recognized " i tried to instal my other Gnex on the same laptop .. it worked .. i tough now i could do a sideload but .. when plugged in the other gnex (the one without os) same message . "device not recognized"

It's not the 1st time i deleted my os .. but 1st time that i could not sideload.. or get "device not recognized"

It's there any solution ? or i should get my other leptop back ?
Tancks for help and sorry for my english :) (i'm from romania)
