I have a Samsung c5520 that we bought a couple of years ago as a spare phone and have never used it ourselves. My sister's phone died and she used this one for about a fortnight. We're trying to do a factory reset on it, but it's asking for a password. We've tried all the usual suspects - 0000 , 00000, 1234, 12345, so we're assuming she has set one. She is unlikely to remember what she made it though.
I came accross this site, and am wondering if anyone can tell me whether it is safe/reliable please?

Anything with online in the domain name degree revs your suspicions. Be careful.
