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.

Yes, you can. but be aware that you will lose t mobile features like wifi calling which is really useful.

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!
Hi all. I am new to all this and the more I read the more confused I become! I bought a T-Mobile T999 with a bad IMEI. I unlocked it and am using it with my Mobilicity SIM card.Everything is working fine except for the wifi hotspot. Also the T-Mobile bloatware is getting in the way. Iwas on my way to rooting the phone when i thought to myself... would it be possible to flash the Mobilicity stock firmware from the SamMobile sight onto the phone. If this doesn't work would I be able to flash the stock TMobile firmware back to the phone? So on the T999 can I flash the Mobilicity T999VVLDMF2_T999VYVLDMF2_MCT firmware from SamMobile
Thanks to any and all who might help.
No to all.

I got this T999V samsung s3 phone with wind network , one of my friend took it to another country. He asked a technician to unlock this phone. Somehow he unlocked this phone to work in that country. When he got it back in Canada, its not picking up its original network which is wind.
I flashed stock rom (downloaded from sammobile for 4.4.2 T999V) , but still not getting wind network. Its working okay with rogers network but not with wind
Any advice
