Question [Q] Getting ZTE Open to 1.1

I recently got a ZTE Open via ebay UK.

First thing to do is upgrade to 1.1 to get fastboot functionality, unfortunately only one of the two downloads on ztedevices.com for the zte open seems to download to my computer correctly, and that is 2014012010220351.zip which from what i've read is for taking a 1.1 to 1.1 with fastboot enabled.

The other download 2014012010205829.zip which is the one that I think I need takes hours rather than minutes to download, and once downloaded nothing on my PC thinks it is a valid zip archive.

Questions
Has anyone successfully downloaded and used contents of 2014012010205829.zip ? -

Thanks in advance
