Remember Madosma Q501 by Mouse Computers Japan? Well as promised by Microsoft, windows 10 mobile upgrade is currently being rolled out to the Japanese users. It is also being rolled out to these windows phones – Lumia 1520, 930, 640, 640XL, 730, 735, 830, 532, 535, 540, 635 1GB, 636 1GB, 638 1GB, 430, 435, BLU Win HD w510u, BLU Win HD LTE x150q and MCJ Madosma Q501.
The update has been promised since end of 2015 but Microsoft kept procrastinating it as the company wanted to tweak it further before releasing it to the public. We suggest doing a hard reset after installation of software just to make sure all the unrequited data is removed. It is not required but one is suggested to do it.
