Bad means corruption. Do the zips open on pc

 

Can you open it once on sd card via windows and android file manager such as astro?

 

You can only use the versions that match your hboot, but I dont see how that would effect the zip being opened, if it opens once on the sd card, via a file manager.

Can you flash non-sense roms ok?

 

Don't some of the new sense roms require a ext partition on your sd card? What rom are you trying to flash. Do you have a ext partition?

 

they all do as far as i am aware

 

Would not having an ext partition cause this type of error?

 

I know suroot will probably suggest to partition your card using gparted. It seems to be the most reliable way to do it. But then again, I'll let him answer.

 

As Dnick says, I think this is a problem with your partition, when you download the rom, which version are you trying to use? I know insertion has 2 versions so I'm guessing the others do. Try and download the a2SD version and see if that works ok, if it does then its defo your ext partition that's creating these problems, well I hope so anyway.

 

Have you ever re-sized your System partition at anytime? It may be too small. Does it give you that erroe immediately or does it appear to load a while? It may be worth you re-flashing recovery.
