bootloader unlock for Huawei fusion y536a1

I have searched for days throughout posts threads here and online. I have as said fusion y536a1, I am rooted with kingsroot I have found all the threads for this phone included the modified twrp and can't wait to move forward but I can't find the code or other method to unlock my bootloader, and for reference do not have access to a computer. AT&T is lost and Huawei tells me they can not provide the unlock code. Someone please help!!!
