[Windows Phone 7 Development and Hacking] GoodDayToDie:
Italian translation of the last line:

First problem: Post in the correct thread. You shouldn't create a new one, especially if that new one amounts to a question, in this forum section when the original subject (CAB Sender) is still around.

Second problem: You can't use other peoples' backups. They are locked to specific devices. If you updated using the CAB Sender, you should have creted a backup yourself. To do otherwise is to risk very great problems for minimal gain.

Third and biggest problem: READ THE CAB SENDER THREAD! This is an extremely well-documented problem! You need to install the correct language CABs along with the 8107 update, or your Phone app and Cellular Settings will stop working. Many people have hit this, and the solution has been posted many times in the replies as well as in the original post.

The fix is simple: install the correct 8107 language CABs. It is recommended to install them all at the same time, but you don't need to. Different phones need different language files. There's an app that will tell you which languages your phone needs, although you really should have run it before upgrading to 8107 (I don't know what will happen since you did it this way). If you just install the languages that you actually need (Italian, I guess) that will let the phone work again, but you won't be ble to receive future updates automatically (it will be "Walshed").

Finally, some comments that really apply to everybody and every hack, but are being posted here in the hope that people will read them:

1. *ALWAYS* read the full instructions! If you don't understand (for example, because they aren't in your language and you can't get a good translation), don't use the hack until you can get the steps clarified! That stuff you don't understand is probably important!

2. Read the thread for a hack before using it! If it's extremely long, at least read both the first few pages, and the last few. Chances are, if there are known problems with the hack, they'll show up in those first few and last few pages. Reading ten pages or so of forum posts is a small time commitment compared to messing everything up!

3. Always, *always* make a backup before trying any serious hack. This goes ten times over if you're using a tool that has the ability to create backups built in; there is quite literally absolutely no excuse for not doing so then!

4. If you experience a problem, you should *SEARCH* before you *POST*! Actually, this is always true, but especially true on hacks like this one, where there's a long thread dedicated to that particular hack, and lots of references to it online. Search the thread, search XDA-Devs as a whole, search the entire WWW, but search! You could have found the answer to this in less time than I took you to write your post, never mind the time it took for me to reply to it!
