I have an unlocked Note 2 on Straight Talk AT&T. So I don't get LTE, and I want to turn it off. But AT&T RAT-locks their modems, so I can't. I know how to temporarily turn the RAT lock off, but all I can do is set the phone to only use HSPA+ (as in no EDGE either), and on top of that the menu option is missing for "Network Mode."
I've seen someone flash an i317M modem on a T889V succesfully (after trial and error and having to restore a QCN backup of their IMEI). What I'm asking is if I can flash an i317M modem on an i317. They're basically the same exact phone (unlike the T889/V, which is slightly different). Has anyone tried this? I just want to do this to be able to change frequencies whenever I want and turn off LTE. I hate that Samsung and AT&T locked us out of this menu. I know that all Canadian models (and the T-Mobile model here in the US) have the menu option.
TL;DR: Anyone try this?

I have the same issue.
I tried flashing the Rogers modem on my AT&T phone and it went into a boot loop.
Flashed the AT&T modem back and all was well.
What gives? If these phones have the same hardware.

Someone got an i317M modem on their T889V. They said they restored their QCN backup after flashing the modem, but it's impossible because the phone reboots like a minute after booting.

The person I'm talking about described it in a lot of detail and said in the end he has to stick to i317M modems otherwise the phone bootloops. In the i747 AT&T S3 section, someone provided a bootloader for the T-Mobile S3 (T999) and converted it to a T-Mobile S3 (with AWS) while retaining LTE.

I am confused and looking for some help. I have a SGH-i747 ATT S3 which I rooted before when I was on ATT. I currently unlocked it and then decided to change my rom. Being that I was not on TMO network I downloaded a TMO rom however once it was done I got a no sim error. In this situation is best to continue using ATT roms? I am going to unroot back to ATT and see if that clears the problem. What is recommended in my situation?

I unrooted it and flashed the stock ATT rom back to it and it came back to life thank goodness. just an FYI.
I successfully went to 2ARF4 on this and it's now a G960U1 but I'd like the AT&T wifi calling, is it possible to flash the AT&T software to gain that or does it have to be a AT&T branded device for their system to register it? If it's possible which OS version should I get, I don't see a ATT version of the one that's on here or anything that would be the alternative.
You can get Sprint S9 or S9+ variant unlocked through Ebay:

Also can do Bad IMEI devices also.
After you're unlocked should convert to ATT software when you insert sim.

It hasn't converted to AT&T software on the U1 firmware I flashed. That's why I started the thread to see if anyone else has been able to

First SIM unlock the phone...
Then, Use an unlocked and generic firmware like g960usqs3brj6 and flash with newest Odin.... Use csc NOT home csc and do NOT insert a SIM....
Factory reset, boot phone and setup to home screen... Then just pop in an AT&T sim and click restart device. It should install everything you need for att. I am running att video calling and all other features on my g960u with the above firmware and have no problems... Lists ATT/ATT/SPR under service provider now... Good Luck!
Has anyone had success with installing carrier firmware on an unlocked phone from a different carrier? I am able to flash XAA (unlocked) software to the phone but haven't had success with verizon software. After installing the unlocked software, I lose the original T-mobile screen when powering on along with all the bloatware. However, if I try to flash verizon firmware onto it, it reverts back to T-mobile screen, bloatware etc.
I've tried the following:
TMB-->VZW (fail, stays TMB)
TMB-->XAA (success, even changes phone info to SM-n975u1)
TMB-->XAA-->VZW (fail, reverts to TMB)
VZW software used was for SM-n975u as that was what people had success with when I looked through forums.
I'm going to leave it with unlocked firmware for now but would appreciate any tips with flashing verizon firmware. I'd like to get all the verizon features if possible.
Are you trying to use you T-Mobile SIM card with it as Verizon? If so, newer firmwares will prohibit that due to the SIM detect function.
Thanks for the response. No, I'm using my Verizon sim card. The call, text, web actually work fine. I was just hoping to get functions like Verizon Voicemail, call filter etc.
Did you boot your phone with the VZW SIM after flashing XAA? You have to do this before flashing the VZW firmware. That's worked for me when I went from ATT --> XAA + boot with VZW SIM --> VZW

No I havent tried that yet! Will attempt it when I get home from work and update the post. Thanks guys!
I flashed xaa and put in my vzw sim, restarted the phone and then tried to flash vzw. Unfortunately that did not work. Still comes up Tmobile.
I'm trying to get my unlocked att Note10+ to Verizon. I hope flashing will get this to work
As of now, I think just using the unlocked xaa firmware is your best option. Download the xaa firmware using samfirm or sammobile and flash it with Odin. It seems to be working fine for me currently. I cant get all Verizon functions like Verizon Voicemail but I haven't noticed many other issues.

Are you flashing the Verizon Userdata as well in Odin?
do anyone have stock firmware for SM-N975U trying to remove the frp on it it a verizon version dont care about erasing the data on it
Out of curiousity why did you want to got to verizon? I have found a software issue with the n976V firmware that locks out verizon MVNO sims. Seems to bypass the sim data per my carrier.
Was looking to go the other way.
Hey guys new to the forum. I have purchased an unlocked note 10+. I was wanting to flash ATT firmware to it so I could have wifi calling video calling etc.. Anyways I have tried this multiple times with no success. I have downloaded what I thought was the right firmware but it still boots up with the samsung logo. When I use odin it says PASS and everything. Can anyone help me out here..?
You need to start from a reset phone. start phone with att sim. it will provision phone and restart. THEN flash att firmware. should boot up to att logo.

So I need to start at the beginning with a factory reset phone with a att sim installed? Also could you tell me where and what firmware to download for Odin?
yes. start from fresh reset in unlocked phone. then you will need to enable "usb debugging" , flash att firmware. (in "guides, news, and discussion" a post by iBowToAndroid) That is what I did to flash att firmware on my unlocked note10+. WiFi calling still does not work, hopefully a call to att will fix this.
Unless the IMEI is within a series in the AT&T system, no amount of calls or fiddling with the firmware will enable it. Even if you manage to get the AT&T boot logo, your carrier features won't enable. I'm speaking from experience dating back to the Note 9 and as recently as attempting with my wife's Note 10 upgrade. If you have a non-AT&T branded device, it will not provision the carrier features. At best, they'll be enabled for a day or so, maybe until a restart.

Does video calling work?

As I stated above, it will not. At best, it'll work for a timeframe of hours to a few days (or until reboot).
