iPhone Which IPSW to download?

[php111]

I have an iPhone 5S and model is A1533 and the carrier I have is Verizon Wireless. If I went to iClarified to download the iOS 8.1 IPSW and would I be downloading the GSM or the GSM+CDMA IPSW?

Connect in iTunes. Under Summary Tab, In the first rectangle click on Serial Number Three times till you reach 'Product type'. This shows your hardware and required ipsw version to be downloaded.

Download the corresponding similarly named IPSW
