Using T-Mobile or Other Firmware on AT&T Note 3? - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

Is it possible? Thinking about Getting a Note 3, But I don`t like the changes AT&T makes. For an example The data icons AT&T puts in there and all the AT&T to go junk. Anyone Flash T-Mobile or other firmwares on there AT&T Note 3? Back when I had my AT&T Note 1 I flashed the N7005 International Rom on it, same went with my Note 2.

The SM-N900A or at&t note 3 has a locked bootloader. This prevents us from installing a custom recovery and flashing other firmware. So unfortunately at this time you won't be able to flash anything. If you were to obtain one anyway and it came preloaded with Kit Kat, you won't even be able to obtain root access. If you are lucky enough to obtain one with android 4.3 you can obtain root. There's even a work around for 4.3 called safestrap. Safestrap allows us to install tweeked roms. But there's not that many of them compared to the previous note versions you use to have.
Many at&t note 3 owners have sold or traded for the T-Mobile variant. The T-Mobile note 3 bootloader is unlocked.
I hope that gives you some insight.

Thank you! Must be the reason why the T-Mobile one will cost me about $35 more used. If I got the T-Mobile Version I might not even root. I just hate what AT&T Does with the Software.

Is there even root on theAT&T Note 3? on 4.4.2? I dont care about tripping Knox as long as it doesnt harm anything

No. There is no root for 4.4.2 as of yet. Avoid the ATT version if at all possible.
BTW thanks for hosting those LG firmwares. It has been very helpful in returning my phones to oem state.

Theres a local Note 3 well somewhat local Note 3 but its AT&T
Been looking at a T-mobile Note 3 for a few days on Swappa for $435

What's the price difference between the 2? I would try the Att if you can get it for under 370. If over that I would do the T-Mobile version. The unlock bootloader is worth it. Just make sure it is paid off (T-Mobile version) before you buy it.

T-Mobile ROM for SM-N900A (Note 3 ATT)

Does anyone know if i can flash any t-mobile rom onto the att note 3? I am rooted and have safestrap !
I thought I could flash the rom onto one of the rom slots. Any advice/links is greatly appreciated
I would also like to know this, gonna help my buddy switch from att to tmobile
Unfortunately it won't work... to the detriment of everyone except AT&T executives.
Besides the n900t stuff not having the proper signatures to run on the n900a, I believe there are hardware differences, like physically removed or disabled frequency capabilities on the transceiver.
Yes! I am using this and works MUCH better on T-Mo
http://forum.xda-developers.com/showthread.php?t=2625946
Make sure you pay attention to the Modificatinator file and add the T-Mobile carrier file after installation. Works fine and much better than stock ATT junk rom.
If I have the n900a from AT&T with a locked bootloader due to upgrading to KitKat 4.4.2, can I still use the phone on Tmobile or am I skwooed? Will moving to tmobile allow me to use custom roms (without safestrap) again?
You will have to network unlock it to use T-Mobile.
No. It will still have locked bootloaders.

Unlock/Root Samsung Note 3 (SM-N900A)

I have a Samsung Galaxy Note 3. I used to have AT&T as a carrier for the phone, now I do not have a carrier. I want to unlock my phone and preferably not pay for it I tried the method outlined at android and me and several other site, ( it involves using the number *#197328640#)
I was unable to use this method because I could not find a UMTS menu.
The only other way I found to unlock the phone was to root it. I wanted to use Odin and CF Auto Root to do but I could not find a version for my device, (Samsung-SM-N900A).
Do you guys have any suggestions for me?
Sir,
Please wait until mods will move this thread to the device specific forum.

Good luck
Im in the same place need to Root At&t galaxy note 3 5.0 N900a where can I find the files
You can only network unlock the phone with a code.
As far as I know, all of the note series is carrier unlocked. if it's not, you have to call your respective carrier and ask them to unlock it. Rooting your phone is another story. I just got off live chat with Samsung and they can't remove the bootloader lock on my OC2 N900a. This will prevent me from buying any other samsung product in the future, not even considering the note 7 b.s.
The n900a is an at&t phone and pretty much every at&t phone is carrier and bootloader locked. Same goes for sprint and Verizon.
Didn't realize oc2 also had the n900a as I thought the U.K. And Europe had the n9005.
Most of the note phones sold by a carrier are network locked.

Why no root?

My M7 was rooted and unlocked before I even put the sim card in. What's the problem with rooting the S6 for AT&T, especially when other carriers are already rooted?
I expected to click the forum and already see custom roms, at least de-odexed ones. Then I find out that the Note 4 STILL isn't rooted after months. There's even a change.org petition to at&t begging for an unlock.
I've 14 days to return the phone, and I think I will if I'm not able to root it by then. No point in having a great phone if it's crippled by bloatware and poorly designed software. What are the odds of seeing a rooted/unlocked S6 running custom roms anytime soon?

I doubt there will ever be root or a custom recovery on the AT&T version. Note 4 only got root and that's if you didn't do the latest update. Search around and you will see what I mean. This is the reason I buy T-Mobile and carrier unlock it for AT&T so I can have root and custom recovery. AT&T = Goodbye to Root & Recovery.

Convert Verizon Note 9 to AT&T Note 9

Is it possible to convert via firmware update a Verizon sim unlocked N960U to fully branded AT&T N960U to get wifi calling and all the other branded features from AT&T? Right now I am using AT&T sim but when my device boots up it shows Verizon and all the Verizon stuff is there. Thoughts.....

Thanks I figured it out.
Just in case someone stumbles on this thread I will post the solution.
You will need to flash the US Unlocked version of the phone then flash which ever carrier you want.
Just for clarification purposes, are you saying that once you flash the ATT firmware onto a Verizon device that all ATT functions work? Or did you have to also provision the IMEI to achieve this as well.?

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

I am looking for the AT&T firmware. I am currently in Kuwait and destroyed my phone. I had to buy an unlocked Note 9 version with the exynos cpu. The problem is I can't WIFI call or use any of the Volte functions my other phone had. Does anyone have the firmware for AT&T? Will that only work with snapdragon? I have already rooted this phone and it is ready to go. I need these functions so I can call back to the States.

Thanks for the quick reply. It looks like I need to wait for Detonator to come out with the AT&T zip. It says coming soon so hopefully soon is in the next couple of weeks. That looks like the best route to go. This is the first phone I have ever rooted. I work with networks and sometimes software kicks me in the butt!

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

Thanks for the info. I read up on all of that and the trade off is worth it. I just need all the Volte features and hopefully the correct frequencies for the U.S. I had a note 3 forever and it got destroyed. I loved that phone. This Note 9 is awesome but without being able to manipulate the IMS settings it is a PITA. I just want to be able to call home from time to time. Emailing the wife is no fun especially with the tech available today. I will keep an eye out for Detonator to provide the AT&T CSCs and all that fun stuff. Then this phone will officially be outstanding. I do have to admit that the rooting process was fun. I am all about modified anything. Stock sucks. LOL

Im not a phone guru like others on here. But from my experience that is all I did. A really important step I didn't mention is leave the cable PLUGGED IN when you flash the unlocked software then the locked software. This caused my device to read the "sim info" and provision its self for ATT and get rid of the verizon stuff and install the ATT stuff. Hope this helps you out.

SM-G973u1 snapdragon root

Sorry to just drop a question, but I can't find the answer. Can the snapdragon S10 SM-G973u1 bootloader be unlocked? If not is there another way to root it?
Thank you
Chris

HelloChris333333, just when you post on a forum the courtesy of saying hello. Yes you can root just with the firmware of your model S10 SM-G973U1 US model so not compatible with EU firmware.

I'm not sure that's true, but I would love to find out I'm wrong.
In my research, the SD phones cannot be unlocked unless you are on (and remain on) an older BL version. The last unlockable BL version was 4, as I recall... if you're running updated firmware you are likely on BL 6. Even on 4, the process was not free and once you did it you could not update to a newer version of FW without losing the unlock.
For this reason, I gave up on getting root/BLunlock on my phone... and honestly, I have not missed it. This is also why I have not seen much development of FW for the SD phones anywhere.
Again, if I'm wrong, I'd love to learn how it's done!
Hello meric57
Can you share a link to the firmware I need? I just bought this phone and there is no OEM unlock option, it is a US phone. If I cannot root it I will have to sell it and get another phone.
Thanks
Chris
I guess another question would be where can I get a S10 with the Exynos chip?
Thanks
Chris
Using ADB I keep getting "waiting for device" and then I find I need to unlock the bootloader. This crap is an endless circle.
U4 can be unlocked before , I can unlock it , Special engineering documents need to be made
I'm V6 nothing available. I bought a G973F instead. G973u1 going on ebay.
Exactly, there is really no root/unlock for snapdragon phones unless you're on a very old BL (and you have to stay there so you can't update). IMO, that's not "can be unlocked" even with "special" steps, particularly since most phones today will have newer BLs (even a year ago, I couldn't find a BL4 phone)... but, yes, it's technically true to say it can be unlocked, but only in very limited cases.
@Chris33333 For this reason, I get that you may want to go to the Exynos instead... I'm curious, if you're in the US, how does that work with carriers? Does it? I've found most US carriers refuse to activate phones that don't match their list of "compatible" IMEIs... I imagine an F-series phone won't be on that list.
I'm in the US using Straight Talk with T-mobile. I've had a Galaxy S5 rooted for years. With straight talk I can use AT&T, T-mobile, or Verizon. But this international phone does not do Verizon.
And StraightTalk will activate the F-series phone without complaint or issues? If so, that's great to hear... because I know VZ and ATT typically won't...
I haven't put the SIM in it yet. Still trying to delete all the crap off the phone.
Lol
