Can I use Verizon firmware in my AT&T phone? - General Questions and Answers

I have an AT&T Samsung Galaxy phone SM-N960U Note 9. It has a locked boot loader so I can't root it. Can I just load Verizon firmware on it to unlock it?

That would more than likely hardbrick your device. The bootloader and modem is way too incompatible between the AT&T and Verizon devices, besides, the Verizon bootloader is locked also.
Have you tried flashing a T-Mobile firmware, it should be compatible and might have an unlocked bootloader already or might be able to be unlocked after flashing it.

[Q] T-Mobile ROM on Verizon Edge ?

I have a Verizon edge that I am currently using on T-Mobile because we switched carriers. I would love to load the T-Mobile ROM on the Verizon phone. is that possible?
If you are using the Verizon version of the phone, even though you unlocked the carrier, it should still be using Verizon bootloaders which are locked up tight. if you try to flash this you'll more than likely end up with a soft brick.

It will not work as the devices firmware is completely different. You will soft brick your device by trying to flash something from a different version.

Carrier/SIM locking has nothing to do with the ROM or root or bootloader.
ThanksThanks

T-Mobile sim-unlocked firmware or any sim-unlocked firmware.

I have a SM-930V(verizon) galaxy s7 and is running Tmobile(930T) firmware. Is there any tmobile sim-unlocked firmware that I can download? Or can I flash the 930U firmware and sim-unlock my phone? What are the implications on doing this? I want to keep samsung pay, wifi calling, and LTEvoice.
You need to get a sim unlock code - there are a few websites you can purchase that from. It is not a firmware change, at least not on the S7.
Correct me if I'm wrong but don't Verizon phones come GSM unlocked or is that only for outside of the country?
Verizon S7 comes unlocked: http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked, Just Flash the latest SM-G930U Firmware available. as always at your own risk of course, plenty of guides on how to flash the U firmware to verizon s7 here at XDA.
My T-Mobile S7 came with a device unlock application... Ive never seen it before, so i tested it out by using the temporary unlock and it worked...

It works. A tmobile rep confirmed that it is now unlocked.
If you do not have the apk for some reason... i grabbed it heres the apk:
mines is factory unlocked (SM-G930U) so am good to go , congrats on unlocking it and you can now flash the SM-G930 U firmware on it and get rid of the TMO bloatware.

Flashing original non modified firmware on carrier specific device

I have a Verizon tablet. I would like to flash a version of the firmware did not come from Verizon, the same firmware that I'd have gotten if I didn't buy it from them and is not tied to any carrier at all. Is this possible without doing anything weird that you'd have to do with a custom ROM like unlock the bootloader? Or can this be accomplished with no complications whatsoever by flashing through Odin?

Firmwares are model number specific plus, Verizon has locked bootloader on every one of their Samsung devices younger than 2 years old and some of the older ones that have been updated to Lollipop or newer have locked bootloader, some are locked as far back as KitKat. If the device you have has a locked bootloader then it's not gonna allow you to flash anything that isn't Verizon firmware.

What is it about the T-Mobile firmware that you hate? IIRC the only difference is international enables dual sim

I just hate the boot logo, bloatware and I heard the international firmware runs alot smoother plus gets updates quicker
Are you asking if the bootloader would become re-locked, or if the SIM would become carrier locked? Are both currently unlocked?
Once you are carrier unlocked you are always carrier unlocked. But flashing international wont make you carrier unlocked. You have to have someone on the T-Mobile side do that for you.

So would the Amazon renewed oneplus 7 pro tmobile gsm unlocked be permanently carrier unlocked?
MSM tool will not relock the sim. The lock is in the efs. And this is not flashed by MSM.so you are good to go. But before flashing ,if you are scared it will lock, you can use qfil or edl.py with the firehose programmer elf .and make a backup of modemst1 and modemst2. With these 2 copyed in the unlocked state ,u will be ok. I have locked and unlocked the sim many times for testing by having backups of locked modemst1 and 2 and unlocked. U can go back and forth all u like.alway back these up ,they will only work for your device. With the same HW I'd.
