in mobile network it says 'UMTS' i was able to make "wcdma only" work (i had to reset the network settings with ##72786# and make the unlock process again) but when is going to connect to 3g it gives me the "LTE esm 29 cannot establish wireless connection" error..also after the reset there is a green circle telling me to activate the phone in sprint (this was a phone with bad esn if im not wrong)..
i used hiapn and all that stuff, upgraded modem to MJA and nothing yet.. i also followed a guide that was made for tmobile.. going to the service menu and modifying a bunch of stuff but it did not work either.
i dont know what else to do.. maybe the issue is that the phone is not activated on sprint?? but im using it outside de US, with a non US sim card.
and yes i also tried gsm/umts a lot of times .
