Folks! The Lollipop update is here and I have just upgraded my Zenfone 5 to Lollipop 5.0
I also managed to document it step by step with screenshots for new users to update without any hassles.

I have covered 2 processes in detail in this post. Scroll down and read as per your need.
1.  Manual update to bridge firmware  ver 2.22.40.53
2.  Manual upgrade to Lollipop 5.0


Since there were bugs the Zenfone 5 bridge update Ver WW 2.22.40.53  was stopped but its needed for a smooth transition from kitkat to Lollipop.So I will Show you step by step to first update to Ver WW.2.22.40.53 manually then update to Lollipop.

There is also a new FOTA update available for 2.22.40.54 WW .If you get that then update it instead of manually updating to 2.22.40.53( but some people mentioned that there are problems updating manually from 2.22.40.54)... so I suggest that you manually update to.2.22.40.53 to smoothly update to Lollipop.



Note :  If you are already on the bridge firmware then scroll down directly to the Lollipop firmware update steps.

Step 1: Download the firmware from Asus website directly on your Zenfone 5. (749 mb)
http://dlcdnet.asus.com/pub/ASUS/ZenFone/A500CG/UL-ASUS_T00F-WW-2.22.40.53-user.zip
You may also download on from your computer and transfer it to the folder shown below using your USB cable. I have done a direct download on my zenfone 5 over wi-fi

Step 2: This will download in the Download Folder in the Internal SD. Cut paste the zip file from the Download folder and copy it outside the download folder into the Internal SD as shown below. (Do not extract the zip file)

Step 3: Then restart your phone by pressing Power button. It will show you an option to Restart .

After restart the phone will show a triangle notification on the status bar . ( If you do not get notification, disable data and reboot)
Pull down the notification panel and you will see that a system update is available.

Tap on that you will get this prompt to select the update package as below. Select OK.

You will get a warning that your battery should be atleast 15% charged. I would advise that you charge above 25%.
Select OK
to start the update process.

Error when upgrading to 5.0 from bridge update, I get to the part where it says make sure battery life is over 15%. Error is "insuffiscient space" (I've 16gb internal storage device) and over 4gb is free!

Got any tips? Should I wait for auto upgrade?

Got right SKU for sure
build # 2.22.40.54
