Samsung Online Support Chat

Obviously this is a Samsung Live Chat rep so I am unsure as to how knowledgeable they are but here is the full transcript of my conversation with them 7/30/2013. I apologize for how long it took me to clarify with the rep but the portion I have marked in red may be of interest if it is true.

Noemi: Hi, thank you for contacting Samsung Technical Support. How may I help you today?

Mac: Hi Noemi, I have a relatively quick question.

Mac: I recently purchased a SGH-i337 3rd party and it is upgraded to the baseband ending in MF3, my question is would I be able to use odin to upload the Google Edition firmware to this phone/

Noemi: Hello. Please go ahead with your query.

Noemi: I understand. I will provide you with the information available on my end.

Noemi: I would like to inform you that we do not have the information on rooting of the device. However, you can use the device to update to a later version. But this will void the warranty of the device.

Mac: OK, would you mind clarifying, what do you mean but update to a later version?

Mac: And I am not worried about the warranty of the device at this point.

Noemi: The version that is not available for the device; the latest version that is released by Google, if I am not wrong, it is Android 4.3.

Mac: OK, would that version be available through samsung or through google? and Odin would be the correct program to upgrade firmwares on Galaxy Series devices correct?

Noemi: I would like to inform you that as soon as the update is available for the device, you will receive an OTA update for your device.

Noemi: Yes, you can use the ODIN mode to update the device to an available update in recovery mode.

Mac: ok, but there is no way to take my ATT branded Galaxy S4 and turn it into a Google Edition without root?

Noemi: However, we do not have the information if the same can be used to update the device to a version that is not available for the device.

Noemi: I am sorry, no.

Mac: OK thank you for your time, last question, is it true that the staged rollout of the MF3 baseband is currently stopped?

Noemi: Once the update is released, you can update it to the Google edition.

Mac: once the 4.3 update is released?

Noemi: Yes, once the update is released for S IV device on AT&T carrier.

Noemi: No, the MF3 update can be downloaded from the OTA update that is sent to your device from the carrier.

Noemi: I am sorry, we do not have the information on whether is has been stopped now. I will provide you with the carrier support details/

Noemi: Please contact them to check if the update is still available to download.

Mac: OK, so right now I am on MF3, thus no Google Edition ROM because of no root exploit, but when the 4.3 update to the ATT Galaxy S4 comes out then I will be able to switch to the Google Edition ROM?

Noemi: Yes, exactly. You are correct/

Mac: OK thank you very much and have a nice day!
