Samsung H720 Down grade NAE to MDC/MDL

phimtau123 · May 3, 2014

I recently Install Fenny-UVUFNB4-STOCK-ROOTEDv1.3 and upgrade my radio to NAE firmware. Is it possible to downgrade from NAE to MDC/MDL?

I want to do this so that I can access the service menu and connect to t-mobile network using this guide

On NAE I can only connect to EDGE t-mobile network.

A sprint gs4 will only get edge and hspa+ on T-Mobile depending where you live.

I got it to work on 3G at one point then i did a stupid thing and update the radio to NAE. Now I'm only getting EDGE.

Is there a way to revert this? I read from various place that is it not possible to revert?

Yes you can revert modems via Odin but you cannot revert software via odin. So just grab the MDC or MDL modem tar and Odin it. I don't know of this will eliminate the Sim unlock that you have right now.

Yea I tried multiple time but it never stick....Odin would say successful but going back to phone i would still see NAE.

And other time i would get a lockout with msg like "Software not authorize by Samsung detect" OR something about firmware update incomplete and to use KIES to complete.

I had to flash stock NAE full spring rom back to get back into the phone.

I got the MDC/MDL firmware from this thread....
