Example – 4.21.40.178Updating Zenfone 2 Using the Update FileOnce you have the files downloaded, you have 3 different ways of updating your phone. Method 1 is the easiest to follow. However, if you have access to a PC we recommend the Method 2 as it is the safest to perform. Our preference – Method 2 > Method 3 > Method 1.Before you begin:Backup all important data (messages, photos; etc). Also, move apps saved in SD card to phone memory as App2SD it is no longer supported in marshmallow. Method 1 – From Within AndroidUpdate to the latest Lollipop version using Settings> About> System update. Make sure that you have at least 60% battery and 2GB of free internal storage. This is needed by the phone to extract the update files. Copy the downloaded update file directly to your internal storage. The phone will show a System Update File Detected notification in a couple of minutes. Tap on the notification. Select the update file and start the update. Your phone will reboot to recovery mode, update and reboot normally. Wait for the apps to be optimized. Enjoy the new software update. You will need to update Google Play Services immediately after the update so that all apps function normally. Method 2 – Update via ADB (PC Needed)We strongly recommend following this method to update your phone if you have access to a PC. There are lesser chances of the phone getting bricked during the update. Download & Install ADB & Drivers to your PC. Turn off your phone. Boot to fastboot mode by pressing and holding the Power & Volume Up keys. Use volume keys to choose Recovery Mode. Press power key to select. Select Apply update from ADB in Recovery Mode and connect your phone to the PC using USB cable. On your PC, navigate to the folder where you have saved the marshmallow update file. Right click while pressing the Shift key and choose Open command window here. Run the following command in the command window. Replace UL-Z00A-WW-4.21.40.184-user. zip with the exact name of the downloaded file. adb sideload UL-Z00A-WW-4.21.40.184-user. zipWait for the file to be sent to your phone and installed. When all done, choose Reboot system now to reboot your phone. Wait for the apps to be optimized. Method 3 – Update via SD CardIf you cannot follow the method 2, consider following this method as it is almost equally safe. Copy the Marshmallow update file to SD card of your phone. Boot to recovery mode by pressing and holding the Power & Volume Up keys and then choosing Recovery Mode. Select Apply update from SD card. Navigate to the update file and install it. When done, choose Reboot system nowWait for the apps to be optimized and enjoy Marshmallow on your Zenfone. You might notice sluggish performance for a while after updating. The system takes some time to build the cache and perform app optimizations. Your phone should perform normally after all is done. If you are not happy with the updated version, you are always free to downgrade back to the Lollipop version. However, the new version does bring some system and usability improvements which you will be missing.

Reply Narender Singh says: December 27, 2016 at 11:35 pm More than bugs, there are these breaking changes which might not be accepted by some. Reduced available internal storage and no app2sd will bring a lot of app installation issues for the users.
