Sprint/Boost XT1526 GSM working

Hi all,
I got my sprint Moto E a few weeks ago. Its working international, but the problem is that its locked to 2G only.
I think its the radio that is locked.

I had a smilar issue with my HTC one E8 sprint when it was updated to Lollipop where the #G part of the radio was disabled. I used this method here to unlock the UMTS900/UMTS2100 portion.

to do this with the Moto E, I need the SPC code to program the baseband. I have had little success with the SPC. If anyone can assist, maybe we can make it a global phone
