Hello, I'm a Lumia 620 user from India, and I have not been able to update to cyan. I'm on Lumia black, Never installed Developer's preview on my phone. As of today, my phone has not recieved the OTA cyan update. Whenever I check phone update, it displays that my phone is up to date. I tried using the NSU tool for retail, but I'm getting error code 0x80131500. I'm really frustrated. Hope someone can help me.:angry::angry:
