I have a Samsung Galaxy Note N7000. An Android update was promoted. I started with the update download, but canceled it at 36 MB (total update size:110 mb) because of slow network. After that, whenever I try downloading it, the download stops at the 36 Mb(exactly at 35.88 where I had previously canceled it).
Interestingly, it is the same case with app downloads also, from Google Play.
Device: Samsung galaxy note - GT-N7000. Android version: 4.0.3
