Help Installing Android on empty phone

[Burn_stick]

I got a phone with android but the factory reset doesn't install android because google play doesn't work (prob. due to the age of the phone (3-4years).

Now I do want to install a new android onto it but I can't access any of the phones settings (like turn on developer options or so). Is there a way to install a new android version?
I have an SD card and I can install ISO files etc. onto it.
I also have access to the phones storage if it tries to install the OS.

Is there any way to do this?

lets start with what phone you have? and so the phone will not boot up?

I got an Coolpad Porto S (E570). Yes it's a china phone^^

Okay the situation just changed. I tried installing android again but this time I skipped the Wifi part. Therefore (i assume) it didn't try to install google play services and actually gave me a home screen (previously it failed to install google play services and didn't boot therefore).

Now the play store still doesn't work but at least I can activate developer mode. I'll try installing another android version on it. I will post here further updates.

Thanks for the help so far!
