how did you get it done??

Not Yet ... but you can search for an alternative in the Play Store! There are many such apps available.

Try clearing the Cache & Data of the app that keeps on stopping... It'll Work!

Wait!! What??

Don't Worry... You'll stay on Nougat but all the data on your phone memory will be lost. I would recommend you to create an online back up or back everything up to your memory card before performing factory reset!!
