Hi
Hoping someone can help!
I'm wondering if I can flash the unbranded official S6 edge firmware over my carrier firmware on a carrier locked device? I'm not rooted if it makes any odds.
Reason I want to do this is that I'm with EE who take an age to release firmware updates and I'm struggling with the RAM management issue that the latest firmware seems to have fixed. Flashing the official unbranded firmware would obviously get me access to the updates in a more timely fashion.
I had a search around and i thinks the amswer is not but i got conflicting reports as to whether this is possible!
Thanks in advance.

We're you unrooted and carrier locked as well?

My phone was branded but not sure if it was locked. I didn't have root neither.
What I did:
1) Download latest Odin
2) Download any software
3) Extract it (for example with 7zip)
4) Copy system.img and boot img to new folder
5) Download script from this post
6) Put script files in the same folder
7) Run ImgToTar.MD5
8) Flash system.md5 and boot.md5 with Odin
You can also flash recovery and radio with this method.
Why not just download the unbranded firmware from sammobile, use Odin to flash it and be done?
What does the extracting of image files and so forth do?
Odin instructions can be found on the sammobile site where you pick up whatever firmware version you choose (my guess is unbranded UK firmware is a good place to start)

Unfortunately I couldn't get the flash to work. Just keep getting a fail about quarter of the way through, which then needed an emergency recovery using smart switch.
Must be due to the fact that the phone is carrier locked but there are plenty of conflicting reports online as to whether it's possible to flash a locked phone so who knows!

I followed those steps exactly, got succeeded for all the flashes, and I still have all the carrier bloatware. What happened?

The only system file in my tar.md5 in called system.img.ext4 is this the same thing or do I have a corrupt firmware?
I flashed over my carrier (O2) firmware with the unbranded firmware, but since i did that a while back (round about device launch), i've had to keep flashing any updates that come out rather than being able to get them OTA - is this normal behaviour?
It's normal behaviour if you didn't factory reset after unbranding your phone.
If you factory reset it you'll find that it re-registers with the unbranded CSC and you'll start to get ota updates properly.

Hey guys great thread I too want to give this a try but want to make sure I don't brick my s6 edge. I have a branded s6 edge from Japan softbank carrier model 404SC but it's actually SMG925Z. Can I use a unbranded SMG9250 firmware from Hong Kong on my Japan branded s6?

Flashing carrier firmware
Along the same lines I have a galaxy s6 that was locked to "carrier a" i had it unlocked and am using it with "carrier B" both carriers use the same model number device SM-G920W8 . carrier a has not released android 6 yet and carrier b has can i flash carrier b firmware as is or do i have to change a bunch of things?
Flashed stock rom
Hey, i just flashed the stock rom of the galaxy s6 (not edge) over my carrier rom. I was using a sim from a different carrier than the one from the rom and it worked fine, meaning my phone was unlocked. I decided to remove the bootanimation and bloatware from my device so I flashed the stock rom via odin. Everything went right except that my network operator is not available. Could you help me, its the only thread that I am sure i will get help.
search about kernal backup and restore. im not sure about it. but you may need to return to , or restore your first kernal. i think wifi stops working if ypu use an incorrext kernal. each model has its own kernal.
which means, i think ypu can use the samsung kies tool to return to stock rom and kernal to fix it... but im not sure.
there are other harder ways pethaps.. but i dont think anyone has our version of 6.1.1 kernal atm. i dont thibk samsung released it.
i really am not sure. i flashed a new 5.0 rom, but not 6.0.1 yet.
i dont know how

The reason why it is failing is because you are on a high boot loader, you current on V3 while the U1 firmware that you was trying to flash is on V2.. You can only flash firmware that's on the same boot loader.
You would need to download G965U1UEU3ARG7 and flash it in order to be on the U1 firmware...

I don't believe the ARG7 for the U1 hasn't been released yet. I'm still on ARF4, I haven't gotten any updates for ARG7 yet.
But you can get the firmware using the link below when it becomes available. It's the same one I used.

To be honest it takes as long as it takes... Though for the U1 firmware it does appear to be the last one released after the carriers.
I would imagine that before they release a firmware that covers all the carriers they want to make sure it works for the individual carriers... But that's a theory/speculation I have.
Use Odin3 v3.13.1_3B_PatcheD for flashing U1 firmware on your Sprint SM-G965U

He can't because he updated his phone to the latest sprint version which uses the v3 bootloader.
The current U1 firmware uses V2 bootloader.

First time I have ever heard of a Sprint Lease Lock.. Now I am curious over what that is, so off to google searching for it.
Think I found what your talking about... I am not sure if flashing the U1 firmware will work in this case given it's an S9+ and not an S8. Hopefully it does when the appropriate U1 firmware is released.
Depending on where you got the phones from maybe try doing a return and get a refund?

No biggie... Just for clarification (if it helps in the future) you can only flash files with the same bootloader version as what is currently installed. You can also flash bootloader versions that are higher then what is currently installed on the device.
What you can not do is flash bootloader versions lower then what is currently installed.
Finding the bootloader version is easy once you know how. Using the firmware version indicated:
G965USQU3ARG7
The bootloader version is the number before the last 4 characters of the firmware version... In this your looking for the number before ARG7... Since the number is 3 it means this firmware uses the version 3 bootloader.

Got it all flashed and back up and running... Just took a bit to restore everything and all my settings. Haven't seen anything amiss as of yet, sure I won't find out if there are any quirks until I let things settle for a day or two.
** Update 9/10 - So far so good, working like a charm. Even the wifi issue I had where it kept saying my internet might not be available (even though it was, and turning wifi off and back on would make it work) seems to be gone. Thanks for the link kevindevonwilliams

To carrier switch you would need to flash the U1 firmware, then insert the carrier of your choice [not Sprint] then set up device, after download the latest U firmware which is 3SARI4 and flash it.
Do not flash the USERDATA unless it is for the carrier you switching to
I ordered an unlocked model, G965U1 from eBay, but the seller sent me a G965U Verizon. At least that's the firmware that it has on it. I'm familiar with Odin and everything, so I'm wondering if I should keep it and just flash it over to what I want. Is this a viable option, I already had to send back a OnePlus 6T back to OnePlus, so I'm getting kind of tired of sending phones back.
Will the phone be just as good as what I ordered if I flash a different firmware on it, radio band-wise and such?The phone says I do not have a Verizon sim in it but I seem to be getting service from my T-Mobile sim.... Is this because all Verizon phones come unlocked? Sorry I'm just so confused with a different models and different bootloaders and different firmwares, so any advice would be appreciated!
Issue resolved, big thanks to user @jcsww!

What firmware does the phone have, from what US carrier? I I think the only thing you can try is flashing different firmwares to see if it will work. Maybe try converting it to a U S. factory unlocked G965U1, then the phone will reboot to configure the settings and features according to your sim card. No guarantee with this kind of thing tho.

You could try switching to the firmware for unlocked model G965U1, latest is 3ARJ6. No guarantee that it will make volte work though, that kind of thing is definitely hit and miss, and your phone is ideally suited for American carriers. But that's what I would try. You might also want to call up your service provider and see if they can do anything.

I flashed my Verizon G965U to G965U1. I used the patched Odin and used the CSC from the U1 firmware... My phone flashed and wiped, and then it booted up and detected my SIM card, then it rebooted again to configure all the settings based on my SIM card. After I did that I was getting the U1 updates directly to the phone.

Hey all,
I've done some rooting in the past, so have knowledge but it's limited comparatively to the community. I bought an Unlocked Snapdragon S9+ from Best Buy and the AT&T FirstNet service for first responders only works for AT&T branded devices. I wanted to try and flash an AT&T image on the phone if possible. Is this possible? Can anyone offer some guidance on how to accomplish this?

Yep, you can flash the AT&t firmware onto your unlocked device. You would have to download the firmware and then flash it with Odin, you can check the general section to learn more about this and we here can help you through it.
The other thing I was wondering is that I assume that FirstNet works on the AT&t firmware. Technically your phone will still not be an AT&t phone according to its IMEI number, but firmware-wise it will be just as an AT&t phone after you flash it.

I understand. So get ODIN and the AT&T firmware and just flash? I've done rooting before so familiar with ODIN for the most part, just wasn't sure if I needed a specific firmware version based on having an Unlocked device or not.
And to your wondering thought, FirstNet does work on the AT&T firmware and they WOULD still recognize my phone as an Unlocked device(by IMEI) as per the FirstNet tech support agent I just spoke with. However, I'm hoping that having the firmware would make the device more compatible with the FirstNet service

You just need the latest AT&T firmware that you can find(BRK2 I believe, unless the latest pie firmware has already been posted somewhere), and you will need the patched version of Odin that will allow you to flash a different firmware than your device came with. It seems like AT&t firmwares can be hard to find for some reason but there was this thread which has not been updated I don't think: https://forum.xda-developers.com/ga...ck-official-attoding965usqu3brj5-s9-t3866823. But it looks like that would at least get you over to AT&t firmware and then you could get OTA updates up to current hopefully. You might want to ask in that thread for further instructions on firmware and how to flash everything properly. You would want to use CSC instead of HOME-CSC, to wipe and fully set up the phone, and there is something which I don't know about called USERDATA, which I think might need to be found and flashed also.
Anybody have stock at&t firmware for s9+ ? At&t appear to have released it OTA to their phones :
https://www.att.com/devicehowto/tut...89?make=Samsung&model=SamsungG965U&gsi=zzc41v
Also need userdata, apparently. I'm new to flashing stock stuff.
I'm going to ask the same question, as I just noticed this release. I'm using an AT&T branded (and locked) S9+ on Cricket, and apparently, I will not be receiving OTA updates... When the files are available, I hope someone posts here. Thanks!
