I'm not a developer or something even near to that. All information provided here is copied from different internet sources and according to best of my knowledge.
I have tried this on QMobile Z8 only. It's similar to Wiko Ridge 4G and Blu Life One (2015) in hardware specifications.
I'll not be responsible for any harm to you or your device. It works perfectly for me. You may try it on your own risk.

If you don't have a custom recovery, get .
