most likely not, you have a locked bootloader
Any way to unlock the bootloader?

no devices from ATT are basically big locks
I called tmobile and ask them if they could flash my unlocked att samsung galaxy note 4 to the tmobile software. They said that they could not and i have to call samsung. I called samsung and spoke to level 2 tech support. Level 2 told me that i can go to a bestbuy store and visit the samsung shop inside of bestbuy and they can reflash the software. I ask the level 2 person again that i did not want a reflash of att software but i wanted the att software fully removed and tmobile samsung note 4 software flashed. He said again that it could be done because the att and tmobile versions of the phone are same hardware wise only thing that is different is the software. I can not say for sure of this works because i have not gone to bestbuy yet to have it done. I wanted to see first what other people here thought about what i was told. Then i would go and get it reflashed.

Doesn't work that way.
The only Note I ever seen that was crossed flash was the OG AT&T Note 1. There is a literal T-Mobile Rom for the AT&T Note 1. It even lets you use a T-Mobile sim on a sim-locked AT&T Note 1. Problem is it's buggy. and sometimes you would lose a signal, or get random freezes and reboots.
For your AT&T Note 4 to work in that fashion, they would have to make a TouchWiz rom from a stock T-Mobile Note 4 ported to work on your phone. A straight flash or even using ODIN to put the T-Mobile Note 4 Rom to your AT&T Note 4 will brick your phone. Modification would have to be made. Don't worry about the locked bootloader as with previous AT&T Samsung phones flashing TouchWiz roms can be done, you just cant flash Cyanogenmod or ASOP roms that's all.

Is not the tmobile software touchwiz based? I thought it was.

It is, but they can't completely strip your phone of the AT&T software. and dump T-Mobile on there. Someone has to create a modified ROM for it to work on your phone.
Why?? Can they not flash baseband and modem and rom to my phone without brinking the phone?

Hey, man from 2017 here.
I stumbled upon this post while I was trying to figure out what the hell I just did to my phone. I've spent the last 4 hour of my life trying to unbrick my Galaxy S7 Edge; just installing firmware after firmware hoping that it would post with Odin. Right when I was about to give up I noticed something happen on Odin that I had never seen before: a green box that said "pass!" rather than "abort!". I looked at my phone to see if it had actually made it out of this boot loop that I had been dealing with for the last four hours, and to my surprise I saw a T-Mobile logo. This stood out to me because the Galaxy S7 Edge that I own is an AT&T device. I don't have the energy to figure out who I unknowingly managed to bypass the Qualcomm Snapdragon's locked boot loader, I just wanted to share my discovery with anyone who was curious. If anyone is wondering: the device is running perfectly with no lag, I now have all the T-Mobile bloatware (lucky me), I can still connect to AT&T cell towers.
One final note that I feel like I should mention: When I initially bricked my Samsung, it was because I forgot to turn on OEM Unlock and turn off SafeBoot. It's puzzling to me how I was able to unknowingly do something that few have ever accomplished and doing so with all of Samsung's security measures still in place.
Update: Wanted to also mention that knox never got tripped however so far Samsung Pay is not useable.

I think you can cross flash with certain phones and carriers. I flashed tmobile galaxy s7 software onto my girlfriends sprint s7 and it works perfectly gets even better coverage then my tmobile note 4.The phone jst has to be unlocked by the carrier that it!
Wait.....so your saying you took full tmobile (gsm) software and flashed it to a sprint (cdma) device?....and it works perfectly?...and by flashing you don't mean swapping of motherboards?.... Common mistake I'm sure

Hello everyone, based on extremely poor ATT coverage in my area comparing to T-M I plan to purchase AT&T Note 3 SM-N900A, unlock it and use with T-M SIM card.
Would I face any issues in terms of unlocking and data coverage?

Soooo.... why would you want to buy a N900A. I feel like we are missing some piece of info. What about getting the N900T and having the best of both worlds. The modem on the N900A is more restricted than the Tmobile version (surprise surprise).

Really? I'm glad I asked prior to spending the $$$
Other than the firmware the phones are identical, correct?
Right now I borrowed Note 2 AT&T SGH-I317 and it seems (to me) to work OK on T-Mobile.
Yes, the Note 2 was one of the last phones before ATT went crazy and started locking down everything. You could enable the AWS bands of tmobile on the ATT note 2. Here is a guide for the N900T if you go that route. Many of us are doing it. You can use it on either carrier. If you are going to use tmobile you might as well use the wifi calling also. It's free and only on the N900T.

Thank you! But the guide is for using T-Moblie phone on AT&T network, I have the opposite.

I know. My point is that the N900T works perfectly on ATT and Tmobile. It works on both carriers and is the most up to date. The N900T has had J7 for a week where the ATT model just is now getting J5. The carrier specific features like wifi calling are not on the N900A.
Also if you read in that thread I list the fcc bands that are active on the N900A compared to the N900T. They are more restricted than the Tmobile version.

Ok thanks again, all I need is the best deal on either used or new N900T. I don't see any listed on Amazon and pricegrabber brings up three crazy deals price of $700 with signing up with T-Mobile

Yes, you will definitely be happier especially if you are wanting to use it on the T-mobile network.
att sim in n900t? HSPA+<E?
Sorry for barging in just a quick question and this thread seems to be the most logical place to ask. Anyway, I have AT&T and just got the Note 3 n900a. If i got a T-Mobile version n900t and put my AT&T Sim in it if i unlock it, will i be able to use it with AT&T's data like hspa+ and LTE or will i just be limited to EDGE. Only reason i ask is because like you say AT&T is going nuts with locking everything down and Im sure its going to be a pain in the a** for the Devs to unlock the bootloader so we can (when it comes) flash custom recoveries and roms. Just like with my att galaxy s4. I was happily rooted and at the time i didnt flash a rom yet i was waiting to find one i like. (mind you i was on the MDL build) and as forgetful as i am just being stock rooted i never froze the samsung software update and it updated to MF3 build and wasnt able to fash a recovery. so i unrooted, reset flash counter and did a warranty exchange and was lucky to get one on still on the MDL build. the second i got that i rooted flashed CWM recovery and flashed a custom rom so it wouldnt update on me. I just dont want the same situation for when the devs unlock the bootloader and get a flash able recovery so just thinking maybe a tmobile note 3 with my att sim may be the way to go to avoid that. lol Not like the note 3 needs any custom rom with the beast of a phone it is but sometimes i like to switch up and use stock/aosp android.
Thanks and sorry for the paragraph here and my apologies if i asked in the wrong spot,
Dave

This thread is huge but hopefully has everything you would want to know on the topic. Look at the first post.

i have owned a us cellular note 3 for about a year and i got rid of that one got a verizon note 3 and got rid of that one and am going to be getting the ATT note 3 today.
i know the tmobile is the one to get if you like flashing but i was in #cyanogenmod channel and was told the ATT is 2nd best to get if you like flashing.
can anyone confirm or deny is the ATT note 3 good for flashing?
i mean can someone give me a quick run down on what can and cant be done?
from what i been researching myself in this att note 3 forum is alot of problems with flashing custom kernels and flashing the recovery or bootloader.....
basically i leave in about 2hrs for a 2hr drive to get this att note 3.
hope im not making a mistake.
i currently dont have cell service with any carrier just to throw that in there
i hope its sim unlocked like the verizon note 3 was.
The AT&T variant is no good for flashing anything other than roms that use the stock kernel. The bootloader is locked. The only means we have of flashing is using safestrap. If you're getting this phone in the hopes of flashing anything other than touchwiz based roms, then you're making a mistake.
I'm ashamed to even ask.....
Former TMO S3 owner here who switched to Nexus and never looked back. Things are just so much easier now with firmware updates and rooting.
We currently pay cell bills for one of our workers and his wife on our TMO family account. His wife was using my old S3, and without talking to me first, he bought her a SIM locked ATT S6 online recently.
I'm working on a SIM unlock code, that won't be a problem.
I'm right in thinking that there's no (current) way to load a TMO S6 ROM onto the ATT S6, right?
Bootloader still locked up tight on ATT?
I know that in the past some of the Galaxy S phones had hardware differences......are the ATT and TMO S6 variants now the exact same hardware (other than exterior logos)?
Sorry for what seems to be an obvious and already asked question. I know someone asked the same question back in August.....wondering if anything has changed since then.
Thanks for all replies.
Yup, bootloader locked tight, can't even get a root working besides the people who are selling it
I bought a Verizon Galaxy S6 Edge few months ago. Now I moved to T-Mobile. I am using the phone right now without any issues.
There is still Verizon crap on it that I cannot uninstall. Is it possible to install stock or preferably, T-Mobile firmware on this device?
I'll just keep it short and sweet. Practically speaking, no.
Better explanation please
The phones are identical except the firmware. Why would it not work? I would like to do the same so I can access better reception and wifi calling. There's literally nothing different Hardware wise between the diff carrier versions other than what each carrier unlocks or blocks. Can someone give a more detailed reason why it won't work?
This is a great question.... I'd like to know the same, BUT, for me, Tmobile charges too much for single service here in Colorado.
What about just bypass frp?
As far as I'm aware I believe the Note 5, based on the Exynos7420 uses a different modem chip in each carrier. Originally I thought the S6 Edge was still a universal World Phone. But even rooted, some people have still had problems actually migrating from Verizon to T-Mobile.
I've had a tester somehow manage to install a TMobile modem on an AT&T Note5, but it messed up the Device Root Key. Which I do believe is the "hardware baked" signature used to decrypt firmware.

Look at the instructions posted here to remove bloatware. I believe if you substitute the correct counterpart firmware the process is still doable. There is also the De-Bloater v3.90 app that should work as well.

Online specs say yes...some users have had 4g+ speeds
Hardware is same...if you have issues firmware wise, unlocked can be flashed to Sprint firmware and you will get updates from Sprint...I've tested this and even model number changed
Can I flash unlocked software on a carrier phone. I bought the Sprint variant because I wanted to avoid all the BS and now I think I'll be going over to At&t in a month and obviously would like to take my phone. I thought flashing unlocked firmware would trip Knox and really don't want to F that up.
I just tried to order from sammy site and the damm promotion for the card/charger ended last sunday, had to call them and complain that their system was down during last weekend and now i have a ticket # hoping to get the promo code when i order, there site said the promo for note 7 owners is til 10-3 but in tiny print the other is til 9-24, ****ty

Yes you can flash unlocked firmware on carrier device. Flashing factory official firmware does not trip knox...only custom flashing does
