  • Hi, I am surprised to find such a good website. Thank you for your great work. In fact I bought a lumia 1020 with a broken pin contact to repair it. I unsoldered (heat gun) the metallic thing on the sim socket to have access to the damaged socket. I ordered a new one from ebay. Before soldering the new sim socket I would like to be sure everything is ok. The problem is that under the sim socket, there were “only” 10 tin points (don’t know how to call it, but I mean the metallic point where I have to solder the sim socket), it seems that 2 of them are not present. I know that there should be 6 points (because there are 6 contacts for the sim)+ 6 point to hold the socket maybe? but 2 could have been damaged.. is it possible to find a picture of a Nokia 1020 pcb to be sure? thank you

    • Pompom I understand your problem, but really sorry at this moment I don’t any Lumia 1020, so I am not able to guide you in this case. I need to see the circuit for that, but alas i don’t have that with me at the moment.
