reload interrupted

hi
i woke up, switched my z10 on as usual only to find it stuck on the loading page after it writes blackberry where it shows how many percent it has loaded (not showing percentage anymore). i left it the whole day, no change
so, i connect it to my blackberry link and try to reload the os, i left it at 37% and went to sleep, woke up and oh no! my pc had shut down meaning interrupted reload
i try to do the reload again but it now says no available update .
i tried web update but it doesnt show my pin
what do i do?

you will probably have to load a leak ,
