On boot up, Rainbow Screen was viewed, but after that, below black screen (with 4 raspberry pi logo) was shown.... I tried various commands to open 'raspi-config' to get GUI but didn't succeed,

Only the Red LED is continuously On.

    It doesn't appear to have finished booting. Could you edit your question and include details of how the green LED flashes during boot?

According to https://elinux.org/R-Pi_Troubleshooting this could be several issues:

  1. Bad SD card, either the creation of the SD card was unsuccessful or it is a bad card.

  2. Bad power supply, USB cable...

Check trough the troubleshooting page and check your system.
