I'm gonna say this is not possible. Even if the kernel was to support somehow the Lumia 1020's components (which I doubt it can), one doesn't have access to change the boot manager.
I think it would be easier for you to sell the 1020 and purchase and Android device.
That's a pretty sweet phone. But if you're looking for Android or iOS, then you better just sell it. You're not gonna get either of those on your Nokia.
Even the good folks over at XDA haven't figured that one out. There's not a ROM that you can flash that will work.
Well that's odd - no app is working for you? None whatsoever? Did you even unlock your screen? Do you even OWN a Windows Phone? I bet you don't...
i think he meant that non of d good apps are working in his phone ..... this windows phone sucks because we cant even share the videos ....... there is only 4 to 5 good game which are present in windows store ..... i m also having lumia 625 . so , i m telling you every thing with my experience ..... there is no way , where you can compare windows phone with android .
You are never going to be able to do this... iOS is locked to the iPhone and the Lumia 1020 wont let you install Android on it...
You had better sell it and look at other options... Though nothing can match the 41MP camera on Android or iPhones at this time
