Hi,

I have in hand Sprint S4 Galaxy S4 L720T. I have rooted it. But tried downgrading the baseband and it keeps failing. Please Mr Blang or anyone else help in unlocking this phone.

Thanks

You mean flash L20 to L720T????

Or Just flash L20t File from support to phone and try again?


Thanks

Still cant get to downgrade the L720T modem. The modem file that works on the L720 does not work on the L720T.

Please has anyone successfully unlocked the S4 Sprint L720T?

I still need help unlocking my L720t from Sprint USA. Can anyone confirm if the model is LTE networks only? I am seeing GSM options in the menu though.
