Downgrade Android Marshmallow

[Bornloser]

I have this BLU Grand 5.5 phone with Marshmallow. Having a hard time figuring out how to downgrade Marshmallow to Lollipop. Never had a problem with Lollipop. The problem with Marshmallow is that my widgets do not update (weather w/clock, reminder program, battery status). It seems like nobody has a solution. Seems to be a common problem. Very frustrating!! Open to suggestions.

I don't think it's possible to downgrade in this manner, but I can't speak for your particular phone.

You can downgrade only by rooting the phone
