Recommended Posts

Hmm. Test it out :D

Could cause problems though. And if I do unlock the sim successfully what carriers sim cards could I use?

Just as a response, I've tried the method used for the Sprint global unlock via commands sent through DFS, but it doesn't seem to work on the USCC GS4. Didn't seem to break anything either, though.

 

As far as domestic unlocks go, apparently the initial baseband shipped with most carriers' SGS4 was completely unlocked, which is why so many of them quickly pushed out an OTA after release. If you're lucky enough to have the MDB baseband on a USCC SGS4, it was possible to pop in a domestic card, like a Verizon SIM, and have the phone usable on the network. Don't believe there was LTE access, but 3G and calls worked fine.

 

No one seems to be able to get their hands on the MDB ODIN file for USCC, so no real luck there either.

Hello!

Is it possible to unlock to gsm (3G - HSPA...) Galaxy S4 SCH-R970 (prototype)?

Thanks!

Did you read this thread at all?

You mean the Dev edition, right?

No. Most likely not because you're phone doesn't work the way ours does, we don't have one to test or work with and there is no way to know without one.

Unless a Dev gets one, no you can't.

That's good info, but I believe Pitr is talking about the developer edition of the S4, the one running 4.1.2 firmware.

The best advice I can give you is to try it. We can't give you a solid answer or a "how to" without having the firmware from the phone to figure it out.

If you can give us that, I'm sure a more suitable answer can be found.

Yes, you're right! It's developer edition of the S4.

Is this even a GSM phone? If not there's nothing to unlock. It's probably not even locked to begin with... if it is GSM then you could definitely do it.

No it's a U.S. Cellular branded "Dev Edition" or "prototype" S4 - what was used to test the device before it ever launched.  It is USCC branded, it is not a GSM phone that I know of.

 

Again, without one there is no way to tell.
