on boot recovery, i apply (unroot)update.zip
and it says aborted installation...
hm... any idea?
Download could be corrupt. Maybe you misspelled "update"?
If you're on Windows, it might be appending and extra ".zip" at the end that you cannot see. There is an option to not hide file extensions in Windows I just don't remember where that is at the moment
OK, the only other suggestion I can offer is to make sure that there only one ".zip" extension and that there are no spaces in the name in front of the ".zip".
If neither is the case perhaps something on this thread will help you get mack to stock
