It seems the long wait for a Windows 10 OTA is almost over for a lot of Lumia users. In a recent post T-Mobile Germany announced that the update is imminent for a number of Windows devices. But, before you get too excited and start furiously checking the update menu, the carrier also adds that the packages can take up to two weeks to appear on Microsoft servers, so a bit more patience is still required.
The first wave of Windows 10 updates for legacy Lumia devices was originally scheduled for December 2015, but later postponed for "early next year", bringing about a lot of fan disappointment. On the plus side, however, the list of first-wave devices is actually longer than expected, featuring the Lumia 535, 635, 640, 640 XL, 830 and 930. Below is a full list of the expected packages with their build numbers. It appears that the Lumia 950 will be getting an update to its Windows 10 ROM as well.
This initial batch of eligible models is slightly different than the range that was originally hinted and included the Lumia 630, 635, 640, 735, and 830. It does, however, match up with a subset of the official eligibility list, released on the Microsoft website. That being said, we can probably expect builds for the Lumia 430, 435, 540 and 735 soon as well.
