Guys, you need to install the language packs for English and currently selected language at least!! In order to let all updates function properly, you actually need to install all language-packs for all currently installed languages on your phone. Use the xap from the opening post ro check your languages. If your language is not available here as update for 8107, then don't update yet!!! That info is also in the opening post.
