--==Downgrading & Rooting Oppo A37fw==--​

You’ve been searching for lots of tutorials and videos for rooting actual Oppo A37fw. I will keep updating this post and make it as easy as possible to help all Oppo A37fw users. For proof check screenshots. Yes it is possible to root Oppo A37fw but it’s quite hard and takes long time. Rooting Oppo A37fw firmware is not possible so we’re going to flash Oppo A37f flash files on Oppo A37fw and then root it and again apply OTA updates of Oppo a37fw to resolve some errors. This won’t remove your superuser access. Just understand it first and then move ahead. Videos on YouTube helped me out. It was hard actually but I’m able to root it and work on it easily.
