Flashing G925T Rom on G925A (Service now with T-Mobile)? - T-Mobile Samsung Galaxy S6 Edge

I think I know the answer is no. But I can't find the answer for sure.
I have had a G925A for about 2.5 years now got it at launch. After 10+ years of AT&T I left for T-Mobile. I might get the V30 when the price goes down or wait till the S9's come out. Want a phone with the new 600mhz band. What I am trying to figure out if there is any way to flash a G925T rom on my G925A. I know the drivers for the modem could be a issue. I also now the boot loader is locked with AT&T and it is not with T-Mobile.
Is there any way around this? Or am I just stuck with a AT&T stock rom?
Thanks for any confirmation.

Baseband with the Metro ROM is G920T1UVU1AOCH, but the problem is, I flashed both of the S6's I have here to the Metro ROM to unlock them so I have no idea what the original baseband was lol I hope you do!
Any luck on the S6 Edge unlock? I scour the internet everyday for developments but I havent seen anything I feel like this S6 Edge I have is either going to sit here forever or Ill have to sell it as a blacklisted phone because its financed and I KNOW its going to get blocked.

the fact that baseband has a G920T1 means that it did changed the radio , while every damn firmware i tried never change the baseband ., is good to know though ... and if you have an S6 Edge try this before selling it .. ask to borrow someone's tmobile sim card and try to at least do a temporary unlock if that doesn't work then download the app VyprVPN select germany (i did) with the tmobile sim still in and try temporary unlock again,,, doing this at least it bought a month's use of my phone , maybe a solution will come up later on.

So youre saying that when you flash the Metro ROM to it, its not changing your baseband? I used the one posted by UnlockBase. Were you able to successfully unlock yours?
And yeah, Ive tried the TEMP and PERM unlock on the S6 Edge. I put my TMobile dealer SIM in it hoping that would help as its a free $80 monthly demo line I get for selling TMobile service. I would gladly try that method, but since we sell these phones, a TEMP unlock wont help me I need a permanent solution so once I sell it, Ill know the customer wont have any issues down the road. I have both of the S6's up for sale now that they are unlocked, but I have always wondered if Samsung REGION LOCKS these phones. Ive tested my personal ATT line in it, and it works great, but alot of my customers on eBay export these phones overseas, so Im hoping these new Samsungs arent region locked :/

when you try to flash any firmware with odin it ends on FAIL.. you can flash rom with twrp but baseband remains the same ,, so i dont know if the unlock app from tmobile is tied in the bootloader or radio or something else ... so far i'll just enjoy the 30days left and see what happens after that ... cause after it accepted my att sim card a message will appear reminding me the unlock was to end on Jul01 and if i wanna to do permanent unlock, so i flash a firmware from a canada version G925W so the reminder went away but i dont know if that means that in 30 days i'll be locked again

I gotcha. I did something similar. I flashed the international ROM on the S6 EDGE via TWRP and it told me the code is incorrect. I know the code is correct because if I ever it in with no SIM and the #7465625*638*# and put the code in it says successfull. This is SOOOOOO frustrating. The lock has to do with the radio or the bootloader/baseband.

I am interested to see if that works which it may as the app is not there to retrigger the lock. You never know.
I currently have metro pcs and I bout an unlocked Samsung galaxy s6. My original Sim is too big so I have to go to metro to get a new one but the phone is not reading the new sim in order for them to program it. How do I fix this or get around this? Should I not let metro try to activate the phone?

Is "SM-N920T" Firmware ok, on a "SM-N920A" Phone ?

Hey guys, just had a question. I have a SM-N920A phone. Will it brick my phone if i flash it through ODIN with "N920TUVS5ERC1" thats meant for the SM-N920T Tmobile Note 5. I hate the AT&T bloatware and would like to have the Tmobile Version of the Note 5. Just not sure if the Tmobile Firmware will brick my AT&T phone. Will it work ?
Thanks guys

It will not work. Locked bootloader for AT&T signed software. Maybe it will flash but virtually no chance it will boot. Even if it did boot, there most likely won't be any cell service.
Oh ok, i see. Yeah you problaly need the same basebands or something for the firmware to work. Well, thanks i appreciate it
If you did get it to boot, using an unlocked modem firmware would be the trick to getting cell service again.
Please, please, don't flame me if I bumped this as it's been inactive for a while... but I wanted to know if there was any progress with this?
I also have a Note 5 N920A that I'd basically like to make into a N920T. I understand that the bootloader is unlocked, but where keys exist, is there not a way to unlock it? I've been out of the development community for quite a while and will catch up a little but I hope someone would have time enough to explain a little.
I unlocked this phone and use it on T-mobile but it doesn't get service where the almost identical T-mobile version of the phone does...
What if I left the bootloader alone and just wanted to take full advantage of T-Mobile's LTE bands? Can I just flash an unlocked modem from _____?
What're the workaround options for this?
Please and thanks in advance
I've been searching for the answer to the same, if not similar, question. I'm trying to find a way or work-around to get T-mobile wifi calling to work.

Att note 10 to Verizon firmware and bloat?

Hey I have an att note 10 and I want to use it for Verizon and get Verizon's note 10 version software. I already got the phone unlocked and Verizon does work but how do I get wifi calling to work and get the Verizon logo during phone bootup?

For starters, you need to download the firmware for Verizon, you can try Sammobile or Frija.
Then you'll need to flash that software into your note, that way you'll have Verizon's boot animation. As for the carrier specific features, I remember reading a post on how to enable those. Sorry for not giving a step-by-step guide buddy, but if you do search in the forum you'll find all the tools needed for what you want.

t-mobile firmware help

Hi, my G981A is US, Tmobile carrier. It crashed on me yesterday, is caught in a boot loops, and I am trying to restore it. I have found the Odin software and am able to get it to recognize my device, however, I am unable to find the Tmobile firmware, only AT&T. Does anyone know where the T-mobile firmware might be found? Device is paid off, so I think it is unlocked. Am a bit of a novice at this...just trying not to have to get a new phone if this one can be brought back to life.
Phone is exclusive for AT&T. Yes you can have it unlocked and it will work with other GSM carriers, but there are no Tmobile/Sprint/Verizon variants.

Unlocked ATT s20 to Samsung Firmware

Hi all. Hope this is in the correct thread. Have been reading through this thread and other areas to get some info. Hopefully someone can help me out. Ill give you just some details. S20 plus on ATT. (G986U) Was stuck on July update and ATT was no help. So had it unlocked. Last night I flashed Samsung firmware. G986U1UES1BTIG. (G986U1) (USA ATT). Well since then I have no 5G or wifi calling of course. It boots up to ATT screen and still has all the bloatware. Spent over an hour on phone with ATT today. I told them exactly what I did. The rep from the "advanced" technical team said that the flashing of Samsung firmware or that it is now unlocked has nothing to do with it lol. The weird thing is when I reboot it shows 5G for a few seconds and then back to LTE.
I assume thats to be expected? There is nothing to flash to somehow get the 5G and wifi calling back? I see some mention about the userdata file. Not really sure what that is or if its even available for my phone. And if it would even work. Thank you for any advice or info.
