BLU Win HD LTE (150e EU version) - full backup image?

[BLUinDaFace]

Hi Everyone

Is it possible to create a full backup image of this phone before I update or upgrade to Windows 10 Mobile?

Would be good to know I have a full backup in case I brick the phone.

Does WP Internals work with this phone?

How would I go about unlocking the bootloader?

Thanks

Would an older version of WDRT download an older image (eg. 8.1 update) - I'm assuming the latest WDRT downloads Windows 10 Mobile?

In other words, does it work the same way as their MCT (Media Creation Tool) for Win 10 desktop?

The latest wdrt too downloads win 8.1 . It does not download win 10 .
