Issue with Lollipop ROM file for G800H

Hello guys! Ii'm having an issue with the ROM file for the G800H. I''ve already downloaded 5 times and everytime I open it and try to extract it, it always gives me an error of file corrupted. 4 out 5 times I've downloaded through Sammobile and 1 other I've downloaded from another server with the same error. Anyone had the same issue or error?

PS: It happened with wither the Russian or the Indian Version of Lollipop
