My suggestion, reflash it clean.

On a side note, it's sad to see Android also @maemo.org, I lost some hours on the Xperia X waiting for Sailfish and I lost the count how many times I had to answer 'no, thanks' to fu***ng pop-ups appearing on the phone as soon as i wi-fi connected it after saving its DRM keys.

And that's 85% of the mobile phone market...
