As i earlier told you all that the answer is in the SIM.
Try Gevay CDMA SIM if anybody can and please update.
Have u try remove the SIM? When u used the SIM all settings will be back to 4G settings but when u remove the SIM, all settings refer to phone configuration.
My opinion SIM Card is priority, when it available the phone will read it but when it unavailable the phone will switch to CDMA. CMIIW
I formerly use Motorola Photon 4G Sprint but I'm not a Sprint user, when the phone boot the first time it read is 4G network then CDMA follow by GSM. If 4G available then it connect to 4G if not then CDMA, if CDMA not available then GSM.
