Elephone P9000 - Wireless Update Problems

Hi all - I hope someone can help me out.

Ive just bought a P9000 as an upgrade for my P8000 and i'm not overly impressed yet. Battery life is shocking and finger print reader seems suspect and WIFI signal is up and down.

I had a notification saying there is an wireless update and this update could potentially fix my problems.
I download the update file and select to install it but once the phone reboots, it says file is corrupt and I have to reboot causing the update not to complete .I have screen shots but you cant seem to upload Jpegs to this site.

The phone is not rooted and its running Android 6.0

Has anyone else had problems. Ive searched other threads but cant find anything.

Thank you all in advance.
Andy
