[Q] AT&T to T-MOBILE FLash ROM - T-Mobile Samsung Galaxy S6 Edge

Hi everyone,
Is there a way to flash the AT&T or any other Stock ROM to a T-mobile phone ?.
I'v tried ODIN (version 3.7, 3.8, 3.9 and 3.10) .and I can´t manage to get it flashed.
Tried by TWRP too, and it says thet the zip isnt good.
Thanks in advance.

Not directly, no.

You mean inderictly is it posible? (dont know how is inderectly ).

Yes, but it requires a seasoned developer to make the modifications necessary. I'm not sure why you'd want to do this though as the AT&T version is far more bloated.

Thanks for your reply.
I absolutely have no that kind of skill.
Anyway, the real reason I came up with that idea is because I cant unlock my T-mobile phone, and I live outside the US.
I've heard and read that sim unlocks by code are having problems.

Unfortunately, flashing firmware will not aid you in unlocking. Have you already tried buying a code for your device?

He said flashing a rom not firmware. Someone over in the s6 forums flashed a metro pcs rom and was able to unlock the tmobile s6.

ROM = Firmware. They're interchangeable terms. Also MetroPCS is owned by T-Mobile, so I don't see your point. Flashing software does not unlock the SIM card slot.

There is no MetroPCS firmware for the S6 Edge as they do not sell it.

my bad this works only on s6...didn't realize you had an Edge

Im living outside of usa .
I have flashed my t mobile s6 using metropcs and unlocked my s6 using a code purchased online.
I reflashed my t mobile software and its still unlocked.
Can i update to stock 5.1.1 using odin and have the device still unlocked .
Once phone unlock is done using a code is it a permanent unlock ?

Your phone was unlocked by code. It is permanent. It is not rom dependant. Just like you flashed a different rom than the metro pcs when you originally unlocked your phone, you can upgrade too.

Flash unbranded rom
I have an unlocked G920T (came locked from amazon, but unlocked easily via device unlock app preloaded)
Is there an unbranded firmware I can flash, even if its from a different variant?

Im also interested to know if i can flash a at&t firmware on my tmobile s6. Not for unlock but because the person i gave it to wants to use the ohone on at&t and feel like its an at&t phone. Whatever right? But can i do that? Or would it have to be a custom rom? Orignal firmware would be nice.

[Q] unlocking hardlocked i9195l

Hi,
I just got a S4 mini (I9195l) in Mexico from Telcel and I planned to buy the unlock code to use it in Panama. However, when I insert the SIM from Panama and turn it on I get a screen with a padlock instead of the field to enter the code. I read that this means that the phone is hardlocked.
Can this be changed by flashing a different firmware?
That is, as to be able to enter the unlock code once it has been flashed.
I have some experience flashing samsung devices and with rooting in general.
I'll appreciate any help, thanks in advance.
I can be wrong but i think this lock is embedded in the modem files, so another firmware can resolve that.
I got this lock when i tried India firmware on my unlocked phone, I put another EU firmware and no more lock.
Just hope that unlock firmware exists for i9195L ^_^
i9195 v. i9195l
Has anyone tried to flash i9195 firmware to a i9195l device?
Don't know on thia device I've flash several Samsung "####L" firmwares with "####" with out problems, should work
If yours its knox free then
search on sammobile for an unbranded firmware knox free and have yours in case flashing the unbranded does not work and don't void warranty

Solved it
I tried a couple of i9195 firmware but Odin failed to flash them.
I also tried a couple of i9195l firmware from Colombia and Puerto Rico and once I flashed it the screen said the resolution was off and it wouldn't
boot.
Finally I flashed the I9195LUBUBMK3 firmware from colombia, it booted just fine and the input box for the unlocking code came up.
It is unlocked now and everything seems to be working fine.

Telcel is obligated to unlock you phone as long as you contract is up. If it isn't they won't give it to you. I actually bought the code online.

Hi zombiemcfly

In the two firmwares available on sammobile from columbia, which one you used? columbia /columbia comsel?

I flashed the same firmware and got this unlocking code box. (Tigo - columbia)
usually odin should be able to flash, why it is failing for s4 mini? If i could get an unlocked version of firmware........

Hi, used this page http://www.networkunlockcodes.com/
On an additional note, you might need to do a data and cache wipe once you enter the code to get it to work properly.
Good luck.

How to sim unlock the trac phone sgh-s970g galaxy s4...and possibly others

Ok so this is still a work in progress but it works, and lte works on my att and tmobile sims. Ill post as many screen shots and be detailed as I possibly can so bear with me.....
So i have a samsung galaxy s4 the sgh-s970g, and a customer needed it unlocked so I thought I would give it a try. Its been a fun phone to mess with. So I am on 4.2.2 and this is the only version I have tested on. I havent tested on 4.3 so let me know if it works for you.
So my baseband is MH3. I used saferoot to root the phone and then I used the twrp for the m919 version to get a custom recovery. after this i went into recovery and made a nandroid. I would advice you do the same if your going to try this, because I am in no way responsible for anything that happens to your phone it will trip your knox counter and your warranty is now void.
ok so I have a tmobile sim in the phone the whole time because it gives you a invalid sim message and when you get rid of that the phone is unlocked. Now I flashed the wicked v-8 4.2.2 custom m919 rom onto the phone. And after that i booted it up like normal and had no problems booting it. So when it finally boots up this is what I see....
know with the tmobile rom it is asking for a sim unlock code. This is where it gets a little tricky.. Youll need to download region lock.apk
you can get it from the play store or from the developer on xda, (great app by the way). So now is when i procedded to use spt box to unlock part of this but i believe you can do it without the spt. so just set your phone up and when your done your settings should look like this... youll still have straight talk radio but everything else including kernel is the tmobile m919.
Ok so now go ahead and open up the region unlock apk and instead of pressing unlock your going to lock it. when its done go ahead and reboot it and then its going to ask your for a password again but this time you know it.. Its going to be 00000000, or atleast it was for me but like I said i dont believe spt is needed to reset the efs i believe the region lock apk will do this and it shoould say unlock succesful like this...
the only kicker is anytime you reboot your phone your going to have to run region lock and lock your modem and then reboot and type in the 8 zeros to unlock if someone figures out a better way that would be awesome.. I also believe this method could be used to help unlock the s4 l720t and sm-n900p without the assisstance of sprint. Any feedback and help would be greatly appreciated and enjoy your unlocked phone....

Region away app works only up to 4.3, so I guess you need to downgrade the baseband to L720T's MK3 modem.
No harm in trying.

the l720t was actually shipped with a 4.2.2 rom and if you could find that modem for the 4.2.2 it was originally shipped with you can unlock it

I can only find a 4.3 ROM for L720T not any version before it.
So, just to clarify, do we have to use the ROM or can we do this on stock? I have two of these LTE-T marked phones from Straight Talk that I'd like to use AT&T Straight Talk SIMs with.
tried this on a stock tmobile mdl firmware with the mh3 baseband with no go.. What am i doing wrong?

Yes i have, Tracfone will have to provide an update to fix the issue. Reason is that everytime you enter the code its accepted. But as soon as you reboot the phone it asks for the code again. So not sure how tracfone will handle this.
Well I returned my $250 Black Friday special as I just have no faith in getting an unlock code for these Galaxy S4s as I wanted to use it on AT&T and I had picked up the Tmobile version. I'll have to settled for a used item instead.
So will this phone work with a straight talk att Sim and a tmo Sim as long as its through ST?
After fallowing all the steps I get to the 8 0's hit enter and it just sits at the screen, and says unsuccessful. Sgh-s970g bb:mh3 av:4.2.2
Anyone know of a pay site to unlock this device. The one legit one was for over seas and I'm in US. I tried offering straight talk money and they said this phone needs to be active for 5 more months before they'll provide me the unlock code. I guess you need 12 months of active service to be eligible for the unlock program. The only thing is, is it will only work on a straight talk T-Mobile Sim until then. Tia.
It DOES work. I installed the wikid v8 rom on a SHG-S970G this morning, opened region lock, unlocked modem, relocked modem rebooted, and entered my unlock code and BAM, Successful unlock. Thanks a grand! By the way i bought the unlock code on a 3rd party site. Im now running ATT on the phone.
Straighttalk will only unlock phones purchased on or after Dec 2013, currently active on ST Service & have been active for 12 consecutive months, if you call the unlock department you will be transferred to their automated information center if your phone is not eligible for unlocking, this is just to inform you of the requirements to unlock your device.
ST unlock
I've had mine 6 months... Called them 5 times and they told me everytime they couldn't unlock my phone (sgh s970g). So.. I used CHIMURA to root for free. Installed the m919 twrp for recovery. Installed wikid v8 using twrp installed regionlockaway locked the modem rebooted, entered my unlock code and it gave me a successful unlock. As stated I'm running a Straighttalk AT&T sim on mine.

Do you think a similar technique can be applied to a Galaxy S5 from Net10/TracFone? I tried to use a S902L with my (Canadian ) Rogers SIM card and unsurprisingly, it didn't accept it

[Q] Unlock Samsung S3 SGH-i747M (possible???)

Hello everybody
I have a Samsung S3 SGH-i747M (from Canada) with 4.4.2 and version I747MVLUFNE6 which is locked. It asks for "SIM network unlock PIN".
Is there any way (I don't care for the warranty) to make it work with an other SIM? I am currently in Switzerland.
Thank you very much in advance!
No you'll have to either call the original carrier of the phone and request the code or pay for the unlock code.

There's lots of them out there. Pretty sure eBay has some and you can judge by their feedback and ratings...can't think of any specific ones right now though.

The problem is that I don't know at which carrier belonged the phone and one page that I found,that doesn't require the carrier and I think read that is reliable (swiftunlock.com), does not include the i747m in the list.
Any ideas or any other sites?
Any that offer it for the I747M should work. Don't take my word for it though. Ask the vendor first.
Sent from my SAMSUNG-SGH-T999 using Tapatalk
All the sites that i found ask for the carrier which I don't know or to have the phone rooted and have a version lower than 4.1.1 which I don't .
Is there any way to find out at which carrier it belonged?
Or any other reliable solution?
Please... :crying:
Go yo swappa.com and check the imei. I think it shows the original carrier when it does the check.

Once you are on the 4.3 ot 4.4.2 bootloader, you cannot downgrade the bootloader and the 4.1.1 modem will not work on the 4.3 or 4.4.2 bootloader.
You must be on at least the 4.1.1 dialler and modem.

damnit, just saw this. Is there any way to downgrade to unlock the SIM? What about if im on a different ROM?
There is no free way to sim unlock your phone once you have the 4.3 or 4.4.2 bootloader on your phone.
How to know on which bootloader ( bootloader 4.4.2 or 4.3) I am coz I was able to install a custom rom on my SGH-I747M The rom is dirty unicorn android 5.1.1 lolipop rom so Can I downgrade coz if I remember correctly I upgraded from stock 4.1.1 so can I downgrade to stock 4.1.1 by downloading and injecting it via odin is it possible or will it hard brick my phone and can you give me way to confirm what bootloader I have ???
Boot into download mode and look at the screen. If you see anything about knox, it likely the bootloader can't be downgraded to 4.1.1.

Can you guide me that how to know which bootloader do you have i.e. do I have a 4.3 or 4.4.2 bootloader how would I know that? and also I do have a custom dirtyunicorn rom with 5.1.1 so is it possible for me to flash the 4.1.1 stock SGH-I747M rom to it and then unlock it and then again add my current rom and use it???
Download and install the Samsung phone info app from the play store, run it, and look at the last three characters of the bootloader. If it is mk3 or higher, the bootloader can't be downgraded.

Not quite sure where to put this but I have just successfully sim unlocked a samsung galaxy s3 sgh-i747m on 4.4.2 .This is only prelimary but upon unlocking and inserting a Public Mobile sim I was able to text on a Canadian Rogers S3. No further testing has been done. I first rooted the phone using Kingoroot and then downloaded the phoneinfo app from play store. I then used the app to get to service menu.At first service menu is blank but I used menu ,then key input Q, then back, then key input 0000,then back and then service menu appears. Now I am doing this from memory and no longer have the phone or another one at the moment to confirm this and will update this as soon as I can. But to the best of my knowledge I first went to UMTS(1) ,thenDEBUG(1), then Phone Control(?), then Network Lock.. Perso-SHA256 was on(1) I set it to off (0). I then backed out of the menu and shut down phone.I inserted PM SIM in phone and booted up .Phone didnt ask for unlock code and shortly I had texting service with Public Mobile. I dont have voice or data to check those but cant seewhy they wouldnt work. Anyway can someone confirm this working.My steps may not be exact but if it worked for me it should work for others.

I need some help to downgrade?

You should probably ask in the questions section. You can find official firmware in sammobile or updato (Google search)
Does the custom ROM need a kk bootloader and modem?

Yea it does. I also need to downgrade to sum unlock since tmo is screwing me around.
Downgrading will allow network unlocking using a free method?
As far as I recall, there is no way to force a bootloader downgrade from mm to kk.

I'm not on MM I'm on LP 5.0.2
My mistake, I meant to say LP, not mm as I know the note 3 never received mm from Samsung.

How do I network unlock then? Do I need just the baseband or how do I go about it? Tmo is lying and jacking me around and I'm poor n can't afford a unlock that costs
Flashing different bootloaders or modems will not sim unlock the phone. The cheapest method I know of to unlock would be to buy an unlock code via eBay.

What I'm asking is can I flash the baseband for 4.4.2 and do the service menu unlock as I would if on stock 4.4.2?
I have never heard of a service menu unlock method for the note 3. Do you have a link?

That's my plan for the unlock is the service menu unlock. Can you please get me the KK modem/baseband to perform it please? Or a working link to the modems foe n900t for kk?
Do you have a link to the service menu unlock method? I've never heard of one.
There was a service menu unlock method for the s3 and possibly the s4 but never heard of one for the note 3.
The stock kk modem would be found in the kk stock ROM which can be downloaded from Sammobile.com.
Before flashing anything, I would confirm that such an unlock method works. Playing around with the service menu can wreak havoc with a phone.

I can't use sammobile. I don't have the patience to sit n sign up for it plus out takes,ungodly time,to download anything lol. Would,you or anyone have the files needed on deck? Say Android host sites or a,Google drive maybe?
You could search the general threads for the files you need. Not sure if they are there, but the 4.4.2 service menu may need a 4.4.2 bootloader? If the phone had a 5.0 bootloader, you may not be able to downgrade the bootloader.
How do you use the service menu to network unlock?
I never had a T-Mobile note 3, only the Canadian note 3.

*#0011# I'm guessing. I need the mj2 baseband or before and only the baseband. I have a s8 plus and a s5 but I needs this unlocked so I can resell for more
Are you aware of anyone who successfully unlocked using the service menu? If there was such a method, it probably would have been posted on XDA.

I've only seen and done it myself on a Samsung S II (hercules) on stock firmware and read that it was available on other similar Samsung phones but I never tried it on the Note 3 as I thought Samsung eliminated that option (even though it was pretty hidden)
The option was also available for the s3 on 4.1.1 but it has never been done with any note 3 on any version of the stock ROM afaik.

How can I update my unlocked AT&T S9 (SM-G960U)?

Hi. I have an AT&T-branded unlocked S9 (SM-G960U) and I have not been receiving software updates. The date of the installed security patch is Nov. 1, 2018, and I'm still on Android 8.0. When I check for updates, it says that my phone is up-to-date. My current carrier is outside the USA. I have also tried updating via Smart Switch but it also says my phone is up-to-date.
Is there any way I could get the Android Pie update?
Thanks for the help!

You can use the U1 firmware (Unbranded) you don't need the carrier one, any for the U will work, and U1

When I check out the U1 firmwares, I see different variants listed (ATT, TMB, etc.). As you said, the U1 firmware is unbranded, so why are there carrier-specific variants?

in short, the U1 is a debloated version of stock without the carrier junk. The different iterations will have different modem files that are intended to work best with the respective markets they are built for, globally speaking. Samsung stopped making a separate version for the GSM carriers in the USA with the S8 which is why all the stock image files are now cross compatible. They technically always were, its just that theyre far more interchangable now due to this physical difference no longer existing

So do you mean that the different carrier versions of U1 firmware don't have carrier apps, but have files that make the phone more compatible with the carrier's network?
It seems as though AT&T can only send updates over their network, which I don't have access to because I'm outside the US. If I change my firmware to U1, would I then receive updates OTA in the future directly from Samsung?

they have very minimal bloatware, they might include carrier apps, but very few. They usually have carrier specific radio firmware to allow the phone to operate best on that specific network, yes.
i would flash one in the very near future myself, but im about to head to Mexico on vacation, so im a tad paranoid to do so. Ill do it when i get back tho. By the end of this month, ill be running a U1 firmware set

Please read this, there might be some restrictions still applied to your phone.
Unlock app requires a TMobile account at least.
