Thanks for them instructions abhijit, but I'm not happy about that particular process as I've spent years using android devices and as such the update process was seamless and no need for any additional updating via a computer.
Obviously I understand windows doesn't own blu and it may require additional time for windows 10 to have been tested on Blu HD Lte, but this is beyond ridiculous now, I should have been notified of a windows 10 update, what exactly is the hold up? is it any wonder the windows operating system is struggling to make an impact in the mobile world?
Luckily I managed to get some sleep, but I hope a Microsoft representative is watching this thread and is going to speak to the people at Blu and make the update available.
