Dear Sir:
I can help you to root your x5 Doogee with MARSHMALLOW 6.0.
Please feel free to contact me if you have further queries. I would love to answer all of your questions.
Best Regards,

Hi, I'm crazy about rooting Android phones and flashing custom ROMs. Funny thing is, I'm typing this proposal on a rooted Redmi note 4. I'm also familiar with SP_Flash_tool used to root the x5 dongee.
