Dear armagonfin,
I am writing from Rome, Italy.
May I ask for your help, since you seem very competent on such technical topics.
I have a Microsoft Lumia 640 LTE (bought new about a month ago from Amazon) currently running OS version 8.10.15127.138.
Here are the complete specifics of the phone:
Model: Microsoft Lumia 640 LTE
Software: Windows Phone 8.1 Update 2
OS version: 8.10.15127.138
Firmware revision number: 02166.00000.15103.05001
Hardware revision number: 2.1.6.2
Manufacturer name: RM-1074_1004
Mobile Operator: 000-IN
Product Code: 059X0P7
I would like to upgrade to the OS version 8.10.15148.160 so that then I can perform the upgrade to Windows 10 Mobile.
How can I make the upgrade to OS 8.10.15148.160?
Or even better, is there a way that I can upgrade directly from OS 8.10.15127.138 to Windows 10 Mobile?
I would be very grateful to you if you can help me, because it’s one month that I’m desperately trying to pass to Windows 10 Mobile with no success at all.
Thanks a lot,
Foriero from Rome, Italy
