U.S. models have no access to OEM unlocking even if it's carrier free

If you have a carrier locked US model there is nothing you can flash in ODIN to unlock the bootloader, as odin packages dont touch the firmware. Best you can do is hope an exploit gets found or return the phone.

Might I ask how you managed to flash a different firmware version? What method did you use to flash the A546U1 firmware?
I ask because from what I understand, the A546U version does not have the option to unlock the bootloader and in order to flash anything at all (including another stock firmware), you must first unlock the bootloader.

You can flash any stock firmware without unlocking the bootloader as long as it's official firmware

And what is the process for doing this?
Flashing another stock firmware, that is?
My objective is to flash an official European version so I can go into dev settings, unlock bootloader, the proceed to flash a custom ROM.

If you're trying to do this on a US variant then it won't work

Do you know the reason behind this?
Because my understanding is that having a locked bootloader is the only thing preventing me from flashing a ROM on my US version (A546U).
What else is preventing me from flashing a stock official firmware on my A656U using the method you're referring to.

Odon simply will not allow you to do this

Well that's unfortunate. I wonder how the person who made this thread managed to flash the A546U1 firmware on a phone that was originally A546U.

Odin does allow that for some reason since they're both U.S. firmware

Network Unlock not working - Do I need stock?

I am running SlimKat 4.4.2 on an i747. Baseband = I747UCDMG2.
I received the Network Unlock code from AT&T. Inserted a T-Mobile sim card, and when I entered the unlock code it was unsuccessful. I have seen comments that Network Unlock will only work from stock, but none of the comments seemed very authoritative.
Do I need to revert to stock in order to unlock the phone? If so, will this method http://forum.xda-developers.com/showthread.php?t=2722660 get me what I need? If there is another way to do this, or something else is wrong, I'd like to know about it before going through this.
Thanks
Yes you have to be on stock and use the stock dialect to do what you want to.

I'm sorry, what is the stock dialect? Will the Odin package in the thread I referenced provide me with what I need?

Stock dialer is what is required.
And no, if you flash 4.3 firmware you will never be able to use the free unlock method. Odin flash 4.1.1 firmware only. Then you can unlock. You'll have to factory reset too btw.
DIALER. Got it!
As I stated in my OP, I received my unlock code from AT&T already. I'm not trying to use the free unlock method. Will the 4.3 firmware work for that?

Yes, just enter another carrier's sim card to get prompt for the unlock code.

[Q] Need available AT&T 4.1.1 I747 link to downgrade my S3

This pretty annoyance me when I found link both sammobile or 4shared or other stuff but end up they all super slow (700MB file but transfer rate 1kb/s). I download and get it but end up .zip file and got failed in Odin(in phone appear unsupported dev_type)
So my question is does anyone here have the right one .tar.md5
in Sammobile I747UCDLK3_I747ATTDLK3_ATT.zip (if you can download it for me and upload it back to Mediafire pls....pls I beg you)
or other thing else that could work perfectly.
because I really need it to downgrade my phone so I can unlock sim card.
Thank and big thank in advance
Do not attempt to downgrade your bootloader if you have the 4.3 or higher bootloader. Attempts to downgrade the bootloader can brick your phone.
If you are on the 4.3 or higher bootloader, you will have to buy an unlock code.

Yes. Look around and you will see posts from other owners that attempted the downgrade and bricked their phone.
What bootloader is on your phone?

Sorry guys I'm totally new to this forum, but I too have the NE4 bootloader and was wondering if a Odin downgrade would also brick my phone as well? I want to avoid using Odin because my Microusb port is kind of wonky too. I want to go back to stock because my phone has been acting up, and was hoping to start off fresh. Thanks in advance!
If you have the 4.3 or higher bootloader, do not attempt to downgrade the bootloader or modem to be safe.

Need help on H811 unlocking

Guys I brought a H811 which is already carrier unlocked and I can use any sim available in our country.It's currently on LP 5.1 and I want to install any custom rom based on MM like genisys and so on may be cm also. So I have a question before trying to get root or flashing anything via TWRP or flashing firmware via KDZ that after each flash will it again be sim locked?
After each flash will it again ask for sim unlock code?
Actually I am pretty noob on this things and didn't used any locked phone like this before.
Thank you in advance...

Verizon bootloader relock

I've unlocked my verizon xl's bootloader on the october update and I was wondering if it could be re-locked by any means other than fastboot? like an OTA for example or a ROM flash or an official image flash, etc. Do I have to watch what I flash to my phone or am I safe?

No worries. They can't relock your phone with a software update or upgrade.

Question How to Downgrade Android 13 to A12 or A11

Hello there, I'm a new user on Samsung device. I went to install custom rom on my device. There is no rom for this SM-A225F model, So I went to downgrade. I don't know if this is possible or not, I just asked to know. And developers do not get its source code? So that we can't use custom rom on this phone too, I am eager for custom rom. Thank you all.
If your bootloader is unlocked, you can use Odin to downgrade...unless the bootloader has an anti-rollback.

Yes, I unlocked bootloader but I didn't do it with odin software. I have done this with another device and Bugjaeger apk, which is more simple from odin software.
You can't flash firmware with an APK. You must use Odin or Heimdall.
