Hey,
So I got a telus galaxy s3 phone and I want to reflash the phone using the Bell image via Odin.
Will that mess up the phone or will it work fine?
Please let me know,
Thank you
It'll be fine I flashed stock Rogers ROM on telus phone and have zero issues. Its a same phone for rogers bell and telus.
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.

He will NOT loose Tmobile wifi because he never had it, if he has an AT&T unlocked phone and
odin flashes any tmobile rom there will be no wifi calling because AT&T network itself does not offer it.
The only way he will have Wifi calling would be if he switched from the AT&T network to Tmobile network.
No one will have wifi calling regardless which rom they flash unless they have a tmobile sim card.
hope this clears things up a bit.

Nope, it won't lock or re-lock your phone, once a phone is unlocked properly it will stay that way
regardless which rom you flash and regardless if you're on the AT&T network or Tmobile network.
Do not Odin flash the AT&T stock firmware on a Tmobile phone even if it's unlocked.
If you do you will not be able to make or receive any phone calls.
You can flash AT&T or Tmobile CWM/TWRP flashable stock or custom zip file roms because
those do not contain the radio/modem images like the Odin flash firmware do.
If you odin flash back to stock Tmobile firmware you will loose root unless you re-root after flashing.
As far as bootloaders go, a Tmobile phone requires a Tmobile bootloader, but you don't need to worry
about that if you flash the stock official tmobile firmware with Odin.
All the other tmobile and at&t cwm/twrp flashable zip file roms found in these threads don't contain
any bootloaders that's why they can be flashed on any unlocked and rooted tmobile or at&t phones.

Exactly, the hardware is only a little different that's why we can use the cwm/twrp flashable zipfile custom
tmobile/at&t roms with either the tmobile locked or unlocked phones or the unlocked at&t phones.
The only exception is that wifi calling only works on an actual tmobile phone with a tmobile
sim card which is on the tmobile network whether it's locked or unlocked.

Don't think it matters if WiFi calling isn't enabled.
I thought the hardware between the AT&T s4 and the T Mobile s4 was the same. I thought the reason they received different radio frequencies was in the firmware and not the hardware can anyone confirm ..
I wanted to try to flash AT&T stock firmware on my t-mobile s4 for better performance on AT&T network

I would love the answer to this question too.
The key is the Modem aka Baseband. This is the Radio file and it is hardware and carrier dependent. If you try to flash this you will mess up the bootloader and radio and you have a brick.
I'm too on AT&T network with T-Mobile phone. I'm using the stock MDL radio and it's working fine. I don't notice a difference between the 2 devices on LTE network. if T-Mobile can't lock on to LTE network, AT&T S4 won't either.
sorry to slightly threadjack.... but does that mean if i flash a custom s4 AT&T rom (i.e. "CleanRom"), i will still be going through a Tmobile bootloader \ kernal etc..?
Is there any foolproof way to "convert" an tmobile s4 to an ATT based s4?
Can't you guys just flash a popular custom rom for sgh-i337 variant and then change the radioband (or whatever it's called) sh*t manually? If you ever flash another carrier rom, make sure ur baseband is the original carrier/phone as stated before. And flash ur carrier/phone kernel(custom or stock, doesn't matter) as well.
I believe these ppl created this topic because they want the stock carrier branded firmware on their phone, so that they can have all the carrier specific features on their phone. Third party ROM is not their choice, otherwise there are tones post out there already. I believe someone must be brave enough to flash it to their phone to test that, otherwise, there is no good answer to that.

Hi guys, anyone can tell me if this will work:
I have TMO M991 and I want to use it in Europe but have problem with network signal (not registered on network; missed calls & s... like that).
My guess is that radio is different and optimized for LTE, which we dont have here...
I m thinking of flashing I9505 stock rom and baseband...what do You think, will this improve radio reception/stable network signal?
I9505 is the version used in Europe region...
I honestly tried to find similar topics, no luck so far so pls point me in the right direction if nothing else...
Cheers!
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:
https://m.ebay.com/itm/SPRINT-SAMSU...?_trksid=p3984.m1561.l2649&_mwBanner=1&_rdt=1
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!
