  19. Sumit says:

    Recovery method doesn’t work on Asus Zenfone 2 (it work on other Asus devices) as reported as users cannot see “apply update from sdcard” option from recovery mode. So it’s better to update it via adb sideload.

  30. Sanjay gaur says:

    How many more months we have to wait for the damn update? Asus is really bad in terms of update. Zenfone 2 will be my last phone of Asus. I am done waiting

  31. MASTER CHIEF says:

  32. Blesson Jain says:

    Zenfone 2 ze551ml is not getting ota file..while clicking download it seen that ‘file not found ‘.so please tell the solution for m update.

  33. Portshot says:

    For people writing they can’t download the file, scroll down and read the comments. Post from @s8cloud contains a link, follow it and download; it worked for me.

    As for instructions, all the stuff from the original poster was way more than I needed. I just followed the instructions from first comment, thanks @VilQ, worked like a charm.

    That said, this 6.0.1 update still has way too much ASUS crap, IMO.

    Hello

    I updated just fine but I’m facing some battery draining and sensor problems so I just wanted to get the old version back.
    But when I tried to factory reset, it came back after the process with the marshmallow version.

    Do you have any idea on how can I do a REAL factory reset or get the lollipop vc version back?

    Thanks!
