Help/Support How to update to ios 8 from ios 7.1.2?

[Acehoundzz 5 iPhone 6s 9.3.2]

Hello, I have a jailbroken ios 7.1.2 iPhone 5s and I am wanting to play pokemon Go on that phone as well as my new phone. The problem is, I do not know how to update my phone with it being Jailbroken and also update it to ios 8. I really do not want to continue to wait for the ios 9.3 jailbreak; so, can anyone tell me a way to do this? Anything helps and is very much appreciated.

You can only update to 9.3.2 since Apple stopped signing iOS 8.

Apple stopped signing the iOS 8 firmware, so the only I think you could do it is find somewhere that you can download the firmware from
