I need some help. I successfully followed all the instructions, updated to WP10 on my ATT Lumia 1020, used Interop tools to update the registry to continue to the latest update. Now my phone is showing network locked, and a message is showing this phone is locked to a specific network provider. It is an ATT phone and my ATT sim card. I have tried to reverse the Registry settings, but not sure I have them as they were originally. Any advice or ideas???
Ok, I even reflashed 8.1, then followed this tutorial without going on to intertrop tools, and the network was locked still. So this initial update to Win10 ATT not recognize my ATT Phone. Trying to get ATT to send me an unlock code for the phone, but who knows how long that will take. Anyone know a work around for this. Everything else with the update works fine, just the network lock.
