I can’t download or install any thing from opera mini system. I use nokia 2700. What is the solution to this problem
You need to use the built in browser to download and install apps.
For downloading other types of files try using a signed version of Opera Mini. Many phones block third party apps from accessing the file system unless the app is signed.
