    Does anyone have a Windows Phone that they purchased through T-Mobile. If so what have you heard regarding the upgrade to Windows 10? I have a Lumina 640 that qualifies for the Windows 10 upgrade. I have heard nothing form T-Mobile. Is T- Mobile going to roll out the upgrade to Windows 10.????

    Dan,

    You can use Upgrade Advisor... Most likely it will give you a "Good news, your device qualifies. We are working with your carrier," type of result.

    Truth is... No one knows if or when T-Mo will approve the upgrade for an OTA push except T-Mo. Considering that they dumped the 640 after about 4 months, chances don't look all that good.


    If you use Insider on the Release Ring, the same version is fetched as the recent public Upgrade received by these phones (10.0.10586.xxx): Phones Eligible for Windows 10 Mobile Official.

    Since your model is on the supported list, you can avoid the waiting and wondering by using the Windows Insider App. Select the Release Ring to get the current (Threshold 2) branch and match the RTM build and version numbers. Afterward, you may use Insider again and select Production to un-enroll your phone from Insider, but at least you have W10M. WaaS (Windows as a Service) will deliver future updates within Threshold to you without any Insider access required.

    Or you could stay on the Release Ring and you will get the next public version early as Release Ring in effect is the RTM. This will deliver the most stable Redstone builds to you earlier than OTA push with minimal risk.

    For right now, Windows Device Recovery Tool is only flashing 8.1 to models that did not launch with 10 so it is the way to revert if you don't care for W10M: How can I recover/reset/restore my phone software?

    Thank you for the perfect suggestion. I signed up for the Release Ring branch and the system reached out for the upgrade immediately. The upgrade went perfectly. No issues at all. I think I am going to stay on the Release Ring and see what happens.

    Thanks again for the great advice. I thought that I was out of luck on the upgrade for my 640.

    My next issue is that I can not seem to be able to unlock my 640. I have the unlock code from T Mobile and have placed an old ATT sim card in the phone. The phone just boots up and bypasses any unlock options. Any ideas on unlocking the phone?

    Thanks

    Open the Phone App and dial ##7820# - you don't even need to press "call" it will take you to the unlock screen. Tap the field and enter your code.
