My phone's applications randomly started to stop working and I decided to restart it since even the home screen was not working. Once I restarted it, I got asked to write down a password to decrypt the storage, though I am ond hundred percent sure I have not encrypted anything on my phone. I have taken the phone to a couple of shops to fix the phone but they have failed to get my phone back in working condition. I tried to fix it using the Sony software but no success. I love this phone and I really don't want to throw it away, so it'd be very nice if you could give me a solution. The phone is an Xperia M C1905, by the way.
