How to Downgrade Android on Huawei I have a Huawei CE0682, which by default came with Android 5. I upgraded to Android 7, but the mobile internet has become very slow. 

How can I downgrade my phone back to Android 5?
You can try to just install the 5.0 rom on your recovery. If that doesn't work you need to install twrp recovery. You may find them from xda developers website.
