Prasad,

You don't need the service center. What you need is:

1. Go to Asus Zenfone Max support site here:
https://www.asus.com/Phone/ZenFone-Max-ZC550KL/H­elpDesk_Download/

On the menu choose Android, then on the firmware section and download the latest system which at this moment should be this:
Version WW 8916-13.8.26.110 dated 2018/03/05. Yes it is 1.52 GBytes large file and download to PC might take some time.
2. You will then need to copy this big file onto a microSD card. After copying the file to microSD card, insert the micro-sd card into the phone.
3. Then press power button and volume down button simultaneously and hold it for a few seconds until the phone shows the recovery screen.
4. Use the volume button to move up and down and the menu and choose the option to update system from microSD card.
5. Select the system file that you download that is on your microSD card.
6. When done updating and reboot. Voila.

This video from YouTube shows step 3 onwards.

I am using from 2016 but not since software corrupted, we are not able to factory reset, on visiting the service station they kept with them for 15 days and now they say since it is old model they are not getting software from their head office, now how to use the mobile. Can the company replace the mobile with a new one?

My daughter gave this phone to me in 2018. At first all works fine, however I encountered problem. All the home buttons are not working. It is good there is a one hand operation that I can use. Can somebody help me what to do to make the home buttons works again. My os is lollipop 5.0.2. Thanks for the answer in advance.

I was most curious about this one, because my specs were that it has 4G, 16GB internal memory (minimum), and a good battery life. I purchased one in Malaysia 3 years ago, and I am still using it. Both front and rear cameras give a clear picture, but, of course as I have downloaded app after app (some becoming obsolete), the internal memory has filled up. I find the dual SIM a good idea, but it's best putting the second into a basic additional phone to supplement and support 3G calls. A novel idea if you have a SIM from 2 countries, and don't want to swap the SIM cards in the phone as you travel. I do enjoy the 'clock face' features in its jacket, which are not available in Australia (where I live) and will keep using it while it works. Overall good value for money, but not available in Australia.

Thinking of upgrading, but my Zenfone Max still works. Been a reliable workhorse for years. One of the heaviest smartphones around, but well worth it for the phenomenal battery life.
