[Zenfone 5] Upgrade Asus Zenfone 5 With Latest Firmware Android Lollipop

   I have been stuck with these smartphone from Asus, for being upgrade/update to the latest firmware Lollipop since from the beginning I bought it. I have the first factory firmware because I reset my Asus Zenfone 5 to the factory reset and can't upgrading or checking update at setting menu.
   But today i'm gonna share, How to upgrade Asus Zenfone 5 to the latest update version ? in case you can't download from OTA(Over The Air) or you got error when update.
   I recommended to use manual update with PC and usb cable, backup your data pic,video,music,etc and make sure have enough battery above 85% in case you don't want get low battery when updating the new firmware. So these are the steps.

Step 1
   See what firmware do you have. Go to "Setting > About > Software Information" check at Build number

Version 1.18.30.10

Step 2

   Download from the official web Asus to get new firmware update. make sure download the same version Asus you have WW/TW/CN/CHT and you should upgrade the old version to the another version until you get the latest version firmware.

   Since I have the first factory firmware 1.13.40.51. So I'm following to upgrade 1 by 1 from 1.13.40.51 until get 3.23.40.60. These all screenshoot just example form me. I started to screenshoot 1.18.30.10 update to 2.19.40.18.

Asus Zenfone Update Version :

1.13.40.51 >> 1.18.40.9

1.18.40.9   >> 1.18.40.10

1.18.40.10 >> 2.19.40.18

2.19.40.18 >> 2.20.40.13

2.20.40.13 >> 2.21.40.30

2.21.40.30 >> 2.21.40.44

2.21.40.44 >> 2.22.40.53

2.22.40.53 >> 3.23.40.60

3.23.40.60

   You can download and read description firmware on Asus web there. Why I'm doing this because I don't want get error when upgrading to Lollipop. and I already get 3 times error so just following from old version to the latest version (new version). So if you have 2.21.40.30 you should upgrade to 2.21.40.44 until latest version.

   When you've finished downloading, check and make sure some .zip file should need extract once to get the real file .zip

   File name should be "UL-ASUS_T00F-WW-x.xx.xx.xx-user"

"x" mean number of version, TOOF-WW is version of asus. my asus is WW version. 

   Connect Zenfone to pc using usb cable and copypaste the file from you download to file in internal storage Zenfone

    After that just unplug usb cable from pc and check notification from Zenfone try to update Zenfone.

   You should be patient, from downloading update old version to another version until you get the latest version firmware android Lollipop.

Step 3
   Zenfone will reboot to boot loader and begin updating

   Wait until 5-10 minutes

   You will see the system update being installed. 

   Just wait until it comes to home and show success notification. FINISH

   

   Repeat again until Zenfone 5 finally upgrade to Lollipop

   Now, I have the latest Asus Zenfone 5 Firmware Android Lollipop. I'm using Nova Launcher and Click UI. So thanks for coming all the way over here, thanks Asus, thanks Zenfone and Don't forget to comment or share.
