Sprint HTC One A9 (2PQ9300) Network Locked after Unlock and IMEI/MEID Change

I have a Sprint HTC One A9 (2PQ9300) That I unlocked, then changed IMEI AND MEID. Unfortunately, after MEID change for some reason unlock was affected, so I went ahead and changed IMEI and MEID back to original. I also reset rtn with ##786#, then I went ahead and performed unlock again. Now the phone comes up Networked locked, which shouldn’t happen with a Sprint device. I did 4 more of the same device with no issue after this one. How do I fix Network lock issue?
