Hi guys, I recently traded my Oppo find 5 for a AT&T note 3.
The Find 5 was unlocked and I was using Tmobile. Although the Note 3 is locked to ATT.
I tried using these threads to unlock:
http://forum.xda-developers.com/showthread.php?t=2494634
http://forum.xda-developers.com/showthread.php?t=2475552
the only difference is I used an app called Kingo to root. I also dont have the original ATT sim card that came with the phone, I used an old one I had laying around.
Other then that everything seemed to have gone smoothly. Except after I reboot the phone after the region unlock it says "invalid SIM" and asks for a sim unlock code.
Could you guys help me figure this out? I thought it would be a lot smoother and this is my only phone.
Thanks!
You must have the latest software update. If so your baseband version ends with "mj5".
The 2 threads about unlocking you posted worked on baseband version "mi9" only.
You have to buy an unlock code now.
Sorry!
I bought a used note 5 T-MOBILE 64 GB that was unlocked yesterday. My sim card was working fine. I installed TWRP recovery by ODIN and after installing it my phone boot-looped. So, I installed "no-verity-opt-encrypt.zip" file and rooted the phone with "BETA-SuperSU-v2.68-20160228150503.zip". After that the stock rom booted fine but I the phone turned on it gave the error that non-carrier sim was inserted and the sim did not work. I tried formatting the phone. Installed the nougat firmware updated it and the problem still persistes. Is there any way to remove Network lock? I would appreciate your help greatly
Are you on T-mobile now? I am, and when I called, they unlocked my Note 5 for free, and very quickly.
What I am asking is when I get the Phone what should I do first? Root first then setup for T-mobile then Custom Rom? I have rooted phones in the past all US variant phones. I tried searching but came up empty. Sorry if this has been asked before I'm just not finding it.
I have just ordered a Samsung Galaxy Note 9 SM-N960F/DS 128GB (FACTORY UNLOCKED) 6.4" 6GB Exynos 9810. My intentions are to Root and unlock bootloader. I'm on the T-mobile network. Any suggestions on what I should do first before i pop my Sim Card in.
Thanks in Advance

this will give you knox 0x1
install twrp via odin without reboot ticked, manually boot into twrp with the button combination.
flash alexndrs devbase to avoid rmm lock issues (his rom will also backup your efs, this is vital)

Hello all,
Super confused by my newly purchased amazon renewed note 8. I was under the impression I was buying a refurbished unlocked device, but upon powerup I get the ATT logo. My previous device was an unlocked Note 8 (I destroyed the screen) which I was running on ATT, but I never had anything other than the Samsung logos on boot up, this phone is loaded with ATT apps and stuff, it basically looks like a carrier phone.
My question is what exactly is this franken phone:
From About Phone:
Model Number: SM-N950U
Baseband Version: N950USQU5ARF1
Android Version 8.0.0
Samsung Experience: 9.0
Build number: R16NW.N950USQS5RID
My desire is to get this as close to a stock unlocked Note 8 like I had, or some other debloated rom. What are my options, or how should I treat this device? Just like an unlocked Note 8 or an ATT Note 8?
This is the snapdragon version too correct?
While we're at it, anybody want to suggest a lightweight/good battery rom for this device?
Thank you so much, I've never had trouble doing root/roms but this phone is confusing, heck even getting adb working kicked my ass for a few hours.
Thanks
I have a fully unlocked Samsung Note 9 (N960U model) that I was using with Ultramobile which uses T-Mobile. I popped in my Simcard and phone rebranded it's self as a T-Mobile phone which is typical. I switched carriers and now with Straight Talk and using a Verizon simcard. Phone is still showing up as T-Mobile when it reboots and even has the T-Mobile bloatware.
I went on Sammobile and flashed the Verizon firmware using Odin and that did nothing as the phone still is showing as T-Mobile. I tried flashing the Unlocked firmware (XAA) and same story, once phone reboots, still shows as being T-Mobile. I even brought it to BestBuy and had them flash the Verizon firmware to no avail....
Is it permanently locked to T-Mobile even though the phone it's self is unlocked? HELP!
When you had the T-Mobile SIM installed, did you check to see if the T-Mobile Device Unlock app was installed & if so, did you run it to check the unlock status?
I know phones don't re-lock themselves, just considering the possibilities.....
One other thing:
When using ODIN to change firmware/etc..... if you didn't before, try changing the firmware w/o the SIM Card installed.
Outside of the above, I'm out of suggestions.
I have a T-Mobile Note 9 & used to test unlocked betas of Android 9 w/o any issues.

Funny you say that, the T mobile Device unlock app did install it's self. It tells me the device is network locked (Obviously isn't since it was originally an AT&T phone) and when I click continue, the server is not responding and that would be expected since this isn't even a Tmobile branded phone! My issue is Some of the APN settings on Verizon are different than TMobile and I can't get VolLTE. Any ideas...?
Interesting, never tried Odin without Sim card...When I did flash the unlocked and Verizon firmware and phone rebooted, the phone recognized there was a different carrier sim and rebooted (It did this when I first unlocked it from AT&T and went to Tmobile) but instead of re-branding or switching to a Verizon phone, it just reboots and still stuck with T-Mobile firmware. I want to be clear also, phone works fine with the exception of MMS and VolLTE which I believe I would get back once I switch to a Verizon firmware
I know this doesn't solve the SIM Unlock issue, but, have you manually changed the APN for the SIM Card you're using?

I did, I changed it to Straight Talk Verizon APNs settings. I just don't know how T-Mobile can lock my phone....
Some of the MNVO's Sim cards don't have all the data as the man brand in my experience I would get a Verizon Sim I've had the same problem use it to do the carrier change then install your regular Sim
[/COLOR]I have a T-mobile sim card in my Unlocked Verizon note 9 and it says its locked as well but it isn't. Just change the sim card and it will work just fine. If there is tmobile software left on it you will may have to flash your firmware to get rid of it. If there is T mobile software left you will have to flash your firmware to get rid of it.
My Verizon branded Note 9 is SM N960U. How is yours unlocked?
