Hi!

I am sending this message with a very high hope. Although I would totally understand if you all are busy but I truly hope that either one of you experts see this. 

My name's Yash. I have an ASUS ROG PHONE, the first one and I want to update to android 9 badly. I have never done any update manually, nor have I installed any packages so basically, I am a noob. Please do tell me in the easiest way as to how I can update my phone to android 9. Please please explain it to me considering myself as a 5 year old. I would be extremely grateful for your efforts and I surely will remember you for my life as an idol. Please please do help me

 This is the software info. 

 Tried installing these like people said, to the internal storage but no help. I truly beg you to help me as there are no videos out there on this(which I totally understand, it's an old phone :(. )

Unfortunately, the ZS600KL is an earlier model and has now ceased to receive maintenance and updates.
If you have a need for a system upgrade across versions, we recommend visiting a service center where our staff can assist you.
