Hi.
I have some experience with this kind of company-locked android devices, I test these security locks for some french medical organization and got rid of those in less than an hour. I cannot be a hundred percent sure I'll be able to do it, but I am pretty confident.
Just know that I am a student in need of money to live, so I may not be a pro, but I will try everything I can to help you.
Thanks in advance,
Georges-Emile Bihr
