【ZenFone Zoom ZX551ML】Android 6.0 Marshmallow update

How can I upgrade my zx551ml to Android marshmallow? The download link doesn't work..((

Hello.. Why can't access the link. Please help. I need to update to marshmallow..

I downloaded it at https://www.asus.com/de/supportonly/ASUS%20ZenFone%20Zoom%20(ZX551ML)/HelpDesk_download.  Just make sure you copy the correct file to the root directory

Link doesn't seem to work.  Go to asus.com and click on service.  Enter the phone number and go to firmware.  I´ll try the link again.

Hi. I updated my zenfone zoom to 4.21.40.209. I have a few problems. Camera was too noisy and flickers but when the photo was taken it was overly sharp and pixelated, especially the front camera, the photo is too dark even with normal light conditions. I'm a bit disappointed with zenfone zoom, my asus zenfone max 2015 has a better camera performance than zoom zx551ml. Aside from camera problems. The phone gets too warm, and android OS drains my battery big time. My phone won't even last for a day. I am very disappointed with zenfone zoom.
But what I do like in zenfone zoom, it doesn't lag too much. It runs smoothly and can handle multiple task at the same time.
