UK stock sd 6.0.1 needed

[Guest Yazgool]

Hi all. I have been searching for at least 2 weeks now without the success. I need the sd package to upgrade Ultra 6 from Android 5 to 6. I manage to find several but none of them is UK (Uk10D). The problem is that when I install non UK update, it changes the regional settings and time zone. This would be not a problem if I would have to do 1 or 2 devices, yet I am working on 30+ a day, and all of them are set on mobile Iron when updated. Again, it does not seems to be a problem, but when I install apps which use the date stamps, it messes with the current time and sets a time 1 hour in advance. I can get OTA update, yet it takes ages to download it. Does anyone have a link to the stock Android 6 UK? 

Thanks a lot
