fota failed

hi to everybody! sorry for my eng. plz help me. fota was failed, phone not loaded. not rooted, all is stock from buying. usb not working (was broken). only 1 way - flash from sd-card via stock recovery!! any chances? i think to download full firmware or only update, put it in to sd and flashing from stock recovery. i dowloaded SKZ-G800HXXU1BPE1-20160708172910.zip , but i got messages in recovery: "footer is wrong" and "signature verifycation failed". is there any ways to "repair" it?
p.s. sm-g800H
