Tutorial: How to manually update ZenFone 2 devices into Android 6.0 Marshmallow

Not just me pero maraming nakaka experience na walang prompt for update kahit irestart. i remember back when i was trying to update my Zenfone 5 this way same problem.

Where exactly do you put the downloaded file? I mean the exact file location. Thanks to answer.

Baka naman kasi naka root kayo unroot it first.

I already put the file in the root storage and i also restarted the phone but still there is no prompt or anything. Any help here? Thanks!

Does not work on the 551ML. Its the first time i checked the recovery mode – and that does not work too. Maybe an earlier update f*d my phone’s startup routine. FYI, its not rooted, nor am i running a custom ROM, its basically stock. Being a techblog, YT may have devices just lying around (i might be wrong) somebody should have tested this before posting and this info is already on other sites – no need to repost. This article almost seem like clickbait to me.

You can flash back your stock rom

Anyone tried using ADB sideload? or flashing the rom in recovery?

it’s for beta testers only

Hi. I downloaded the file and placed it on the root storage. I explored some forums then they say that I need to extract the file on the directory then it should detect the files. Sadly, no prompt for me. I restarted it a couple of times but no update notification is showing up. Btw, my phone is not rooted. Can someone help me with this kind of problem?

Dont try this unless you know how to restore your Rom. Not for rooted users, Custom recovery like TWRP, etc. Re-enable any system or default apps that you may have disabled. If your Rom or Bootloader or Recovery have been in any way altered, official updates from ASUS will cause your phone to brick or do a bootloop. This should have been a warning in the article. A manual update is always risky.

If your phone phone gets bricked/stops working because of this, follow the instructions here.

It might take a while, but my phone is now 90% working. (can’t enter recovery and no root access)

This doesnt work. It is still on BETA stage.

hahaha hahaha,i see so many around here that did tryed the beta,pfff,and i see 1 in here even that bricked hes phone trying to install the beta through TWRP,hahaha ,well,first of all for those that thought they are smart,i will tell you how you can manage to install the beta,first of all,the phone has to be unrooted,that’s the first and very important,which it means no TWRP,second,your bootloader has to be unlocked,3rd,your room has to be stock,with all the apps that comes with the original stock rom and unaltered ,that’s why many did bricked their phone,even tho some i see that think they know what they r doing hahaha,now,i just told you how u can have that beta of the android MM for ZE551ML,it is working great and it is stable,i have it and i can say that i love it,the battery it last longer in standby,but ofc i took care of 2 things that always were crap and always will be crap,as i saw in this movie that r ppl that really believe that those craps worth something,1 is the proccess killer,or apps killer and second is that cm security,for the first 1,there is no app in this world that actually do something to kill a process on android,for a simple reason,the apps that those apps try to kill actually have 0 power consumption and ocupy 0 kb in memory,now,that app is useless for a simple fact,it stays loaded in memory,consumes lot of power,it has to stay loaded to search for the loaded apps and try to kill them when they r,that is power consuming for nothing,it was proven lot of times,those apps consume memory and power more than any other app,for the second,i wanna hear just 1 persone that found a virus in hes/her android device ? there is none,not yet so another thing that is useless for now on a phone,so…good luck installing the new beta,if you know what you’re doing…

Why the update need a latest version of lollipop?
Its always failing to update the firmware i download and it has 1.6 gb of size..

During my system update on asus ZenFone max I received the notification of system installed, but I mistakenly cancelled it.
Now when I update my system back again it is not showing me any notification.
Plz guide
