Few questions regarding our GSM capability:
1. What changes between CDMA ROMs and GSM ROMs? Doesn't the Rezound work on both networks since it is a global phone now?
2. If I were to pop in a GSM carrier's SIM card (let's say... T-Mobile's) what would I have to research and do to get all of T-Mobile's features (SMS, Voice, Data, Play Store carrier branded apps maybe?) working?
3. Will I screw anything up by popping a GSM SIM into my phone with a CDMA ROM?
I want to order a T-Mobile SIM and see what their network is like in my area.
if you flash any ROMs based on latest RUU 4.03.605.2.. that will support both CDMA and GSM . nothing will be screwed up!!
So the ota won't work?

I thought you still had to unlock the carrier stuff even though it was a global rom. Thought was still locked to verizon.

Hi, id like to know if the Photon 4G is CDMA or GSM with a Sim Card Slot? because im about to buy one from amazon and id like to know if it is one or both and how to recognize which one is it
It is both, it uses the sim for GSM and uses CDMA without the sim. You cant use a domestic sim for GSM, for now atleast.

Meaning you can't take a sim card from AT&T or another GSM provider within the US and plug it into Photon and expect it to work. Its locked out for GSM in the US. It works internationally though.
The 4g is Wimax !!!

LOL I totally had that typed out ready to post before I reread and saw that he meant the phone and not specifically the 4g. Unless I just misinterpreted that completely lol, which would make it the second time

I have just bought an unlocked Sprint unit from ebay, hoping to use the GSM slot for my primary pre-paid line in Nigeria, and the CDMA slot for one of the CDMA providers in Nigeria as well. I plan to take the unit to be programmed into a CDMA network in Nigeria; that will cost me about US$50. Meanwhile, I successfully rooted and flashed ParanoidROM JB, but I saw that it showed no GSM signal at all with the JB ROM, so I restored the original GB 2.3.5 Nandroid backup. There seems to be very little documentation on how the dual system works. Will I be able to use both the CDMA and GSM together, in a dual-standby fashion, in Nigeria?
I flashed the KDDI radio and cm10 and have used my MoPho on T-Mobile.
Don't forget to thank all who help!

Flash the miui rom
Sent from my ADR6425LVW using Tapatalk 2
Just put the sim card in and use an app such as LTE OnOff (yes, it works on the Rezound) to switch the radios to GSM. The SMS sending problem is still an issue though.
Either the MIUI rom or Joel's PKMN Sense 4 rom w/ gsm patch fully support GSM.
Then use LTE onoff to toggle to wcdma or gsm (it depends which works better for you, idk which one). You might need to add your APN
I'm coming from the Motorola side of things and I do not know which files are the radio files. I'm in need of doing some modifications to try and get the Radio to get Verizon towers. I only have a month or so then I switch to T-mobile but would like to get the LGOG working on Verizon's network. I know the chip is capable of those frequencies just need to modify the Radio files.
I know the Motorola Droids call them .ril not sure for LG.

for gsm i think you just need to carrier unlock the phone then enter the correct apn.
The phone is unlocked but not sure how to enter the APN

Verizion is cdma, you aren't going to be able to activate it on their network because the esn/imei isn't in their system. They like sprint will only activate a phone that is for their network.
This is so far from the right section, even moto forums aren't that backwards...

Yeah, I've tried to no avail. I did get the mbn files to try and get the radio up on Verizon but no luck thus far. So I will be passing this up for now but will continue to tinker.

Refer to topic. So Tmobile recently launched LTE in my area yesterday. I was wondering if there's a way to enable their network on my ATT note. :fingers-crossed::fingers-crossed::fingers-crossed:
I've gotten TMobile LTE with stock settings on my unlocked, rooted (but nothing done with that) i717 in Chicago.

What radio & rom are you using?
This phone is almost two years old but you are the first person to wonder if the at&t note can work on tmobile's frequncies.
Just in case I'm wrong about you being the first one to wonder, why not try a google search?
I'll bet there's 2,000 responses.

Yes, there is. You have to be on an AT&T Rom, Carrier Unlock your I717, Use T-Mobile Sim Card, Apply T-Mobile LTE APN Settings. I think that's it in a nutshell.

Don't forget to get LTE on tmobile you must use an ATT Radio.
UCLF6 for ICS
UCMB4 or UCMD3 for JB.
Rom type doesn't matter, just radio, apn, and being in a LTE area, i717 unlocked as well.

You must also be unlocked for tmobile. Just adding what he forgot. There is a guide in the i717 forum for free sim unlock if it isn't by chance unlocked already.

Being as this phone is from ATT, no it wouldn't need to be unlocked to use an ATT sim.
Unlock is needed for tmobile phone/data to work on the i717.

If your trying to unlock using this guide. http://forum.xda-developers.com/showthread.php?p=37357905 then yes flashing the tmobile modem is fine.
When it is unlocked, you can flash any radio found for the i717 in recovery and it only changes the radio.
So follow the guide to sim unlock for free. Then reflash only the radios I mentioned before. You should then have your ATT I717 unlocked for tmobile if you change out the sim card.
This won't do anything besides allow a tmobile sim card with functioning calls/data.
If you don't need this, then try a newer ATT radio that I previously detailed a few posts back.
I'm looking to S-Off my wife's DNA so I need to upgrade from 2.04 to 2.06. But were using her phone on Net10 Gsm (ATT).
So my question is does the 2.06 firmware upgrade lock down or restrict the gsm network options at all?
I know the DNA was the first and only phone to come from Verizon completely gsm unlocked and other phones im thinking the S3 and others came with cellular unlocked but data locked so u couldnt do what we did and run from verizon with their phone. So if 2.06 restricts gsm access were out of a phone and my wife might even kill me .
Cmon somebodys gotta know if they were able to switch their DNA to a gsm network after taking the 2.06 update?
