Well I can only tell you about the battery. I got mine from Ebay seller htcacc the description said it was a genuine Nokia battery (Nokia bandit), shipping does take a while but when I got it it looked like my old battery except for a year stamp being 1 year newer than mine. It seemed fairly simple enough to install with the tools supplied and I found a you tube video on how to do it. Since install of the new battery I had no issues with it so far. My Lumia 1520 has been on windows 10 and working as well as expected.
As for a repair center I looked into that and it seems they wont touch my version the Lumia 1520.3 since im in the USA so I decided to do the repair myself. I simply searched with google. For the glass you might want to look up you tube video on it you might want to see if you want to attempt it. Thank fully I got mine in a case with a lip around the edge of the phone so I drop it the screen never touches the floor/ground.
