First of all Thanks to you for providing the link to download x150e 8.1 flash image and Microsoft ffutool. Finally I took a risk and flashed x150q 8.1 image (I downloaded earlier through onto WDRT) onto x150e model. I did this cause I wanted desperately to test the win 10 upgrade. What I did yesterday was at my own risk.
1) I have flashed the x150q us rom onto x150e.After flashing the firmware revision no was changed from 15009 to 15008 which is for us model.As expected there was no sim connection.
2)Immidiately downloaded upgrade advisor app. The update was available. After the heavy installation for 1 hour it was successful.The update was started with 10586.107.At the time it was extremely buggy but again checked for the update and downloaded 10586.164 the most stable build.The phone was successfully updated. Again did a hard reset and guess what the phone was absolutely performing flawlessly. I did not find any kind of bug in it. Again I am telling that after what I have experienced I was delighted. Microsoft has done a very hard work on this. Now what I learned is that both US and Europe models has only one difference is that the firmware revision no. But as of now this is the only my working phone so reflashed European rom into phone and reverted to win 8.1 and my both sims are now working perfectly. Now I think Blu has to submit the recovery image not for HD LTE but for JR LTE also. Hopefully Both Blu and Microsoft will resolve this issue.
