Help needed unlock

Hello
I have unlocked my s6 by using the metro pcs firmware upgrade method .
I have reflashed the t mobile deoxed version rom .
All was working fine until few hours ago when my phone stopped receiving network .
Reboot didnt work too until i switched on wifi back on .
Is it something to really worry about ?
One more queery: once i unlocked my phone does it mean its permanently unlocked to any network because right now im residing in asia .

I think both questions have the same answer, you can't use any other firmware other than metro pcs. I remember seeing that in a different thread. If you paid it off free and clear call tmobile and they should permanently unlock it for free. I think all you need is your imei or serial number.

So can i reflash the metro pcs firmware and still have the device unlocked ?
I have purchased the unlock code off one of the leading sites on web.

I called T-mobile and pestered the hell out of them and they in return pestered the hell out me, in the end I have an unlocked phone with no flashing this and that.

I can't give you a answer but why not call tmobile like ipaq_101 did? That way you don't need to care what firmware or rom your on, it will be universally unlocked. If long distance calling is a issue you can use the online help, just make sure the first rep you talk to knows you won't stop bothering them until it's unlocked.

Is it not possible to install a ROM and then, say, flash a MetroPCS modem or something? For the record, I'm in the same predicament; I'd like to flash a ROM, but am running stock MetroPCS firmware that allowed me to use an unlock code.

You can flash any compatible ROM. I Odin flashed the MetroPCS firmware only so that I could permanently unlock the SIM. (I found that the T-Mobile Device Unlock is buggy and not exactly permanent). Then I flashed the international "F" version of Alliance ROM along with UniKernel. Been working great!
As long as you don't ever flash a T-Mobile radio, you'll stay unlocked!

Source for phone with unlocked bootloader

I am looking to buy an S4 Active with an unlocked bootloader that will allow flashing of custom ROMs. I have found a vendor in Hong Kong that appears to be selling the S4 Active with either what appears to be the AT&T configuration ("i537 For ATT"), or a non-ATT configuration ("I9295"). Can anyone confirm that this is what the "I9295" is and if it will work with North American GSM networks? Is there another avenue to get an S5 Active with an unlocked bootloader that I am missing?
Here is the link to the vendor and phone.

The i9295 has the unlocked bootloader that you're looking for. I bought mine off eBay for $200 but had to weed through a ton of items claiming they were the i9295 but in reality were the i537. I used the i9295 on AT&T and am currently using it on T-Mobile. It works great, however you only get HSPA+ and not LTE, I'm trying to figure out it it's just a modem issue where I can just flash the i537 modems but I haven't been able to spend enough time to really figure it out.
If you want an S5 Active with an unlocked bootloader, try searching for the SM-G870F. It's the international version of the S5 Active, so theoretically it should have an unlocked bootloader. There are people posting on XDA who have this phone, so you might want to try asking them.

Thanks for the response.
I just pulled the trigger on one of these.,
http://www.ebay.com/itm/111235467917
I have confirmed w/the seller that it is a T-mobile unit.
In theory the bootloader should be unlocked.

There is no such thing as a T-Mobile version. That is an i537, an AT&T phone. IT DOES NOT HAVE AN UNLOCKED BOOTLOADER. You can see the AT&T logo on the back cover. The phone has been SIM unlocked to work on T-Mobile, but the bootloader is still locked. This not the phone you want. If it's not too late I would cancel the order.
EDIT:
Try this one: http://www.ebay.com/itm/Samsung-Gal...406?pt=LH_DefaultDomain_0&hash=item1c56327bfe
Or this one: http://www.ebay.com/itm/Samsung-Gal...444?pt=LH_DefaultDomain_0&hash=item2803e961ec

Thanks. I suspect that even though the seller said that the bootloader is unlocked and it is a Tmobile phone that you are 100% correct in your assessment that it's only carrier unlocked. I sent a similar message to an S4 Active motherboard seller in California who also told me that all of their mobos had unlocked bootloaders. I strongly suspect that most vendors have no idea what a locked bootloader is...

You're right. If you want to be 100% sure you are getting an i9295 with an unlocked bootloader, have them send you a photo of the phone's About screen showing:
Device Model
Baseband version
Kernel version
Build number.
Those should tell you whether or not it is an i9295, particularly the baseband version which is linked to the bootloader. The other information can be faked if they know what they're doing, but the baseband information is pulled directly from the modem and there is no way to fake it on the i537.

Thanks for the information.
So am I correct in assuming that all non-ATT phones have a Device Name/Model number that is SAMSUNG-SGH-i9295?
What is specific to the non-ATT phones in the Baseband version?

Locked Bootloader = SGH-i537 (AT&T version)
Unlocked Bootloader = GT-i9295 (international version)
The i9295 baseband will say something like "I9295XXUCNE5" while the i537 will say something like "I537UCUCOC6". There an entire list of i9295 firmware on the Sammobile site in case you want to check where the exact baseband is from. So basically as long as it has i9295 in the baseband it is safe to assume it has an unlocked bootloader. When I was looking for my phone the first thing I did was look at the picture to see if it had the AT&T globe on the back cover, if it didn't I then asked for the photo showing the About screen to confirm. As long as both of those things check out I say you have a 99.9% chance of getting the i9295. You're probably going to have better luck with sellers in Europe because that where a majority of the i9295 sales occurred.

T-Mobile stock firmware on SM-G920T factory unlocked version

I recently purchased the G920T factory unlocked version on eBay, is it safe to Odin any T-Mobile stock firmware, any info will be appreciated, thanks in advance.

Once you above a certain firmware you can't go back. What firmware you currently on?

It is currently on G920TUEU3COK1 can I Odin to the latest T-Mobile G920TUVS3DOJC I understand that I can't go back but is it safe and will it function normally, thanks for the reply.

i have this same question because from what ive read 3COK1 is for Cellular South (aka C Spire). while the 3DOJC is for Tmobile, both under the G920t firmware. are you also on tmobile network with this phone?

What are the benefits of flashing T-Mobile firmware on the USA factory unlocked phone? I have this phone on T-Mobile and wifi calling works. I also get great reception. I assume this phone will get Marshmallow months before T-Mobile releases their build

Are you getting LTE on it.

So I flashed the C Spire firmware and it asked for an unlock code. I flashed back to the original tmobile firmware and it is still locked although it was unlocked before, but the device unlock app says its ineligible for unlock now.
Anybody else encountered this?

Call t mobile customer service and ask them. They can adjust their servers and then the unlock app will work.

I'd advise that you dont.
To unlock it I had to flash back to the original tmobile rom. From the tmobile rom, the device unlock app failed in different ways.
After i called tmobile over and over I got it unlocked (like 2 hours of calling).
Hurts my heart to see all the tmobile bloat, especially when i dont even live in the US, but at least my phone works

Carrier unlock a G920T permanently

Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!

The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock
Sent from my SM-G920T using Tapatalk

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.

If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.

I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters

i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.

With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?

I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.

Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Got it done remotely!

I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!

I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.

Please help

Thanks I figured it out.

Just in case someone stumbles on this thread I will post the solution.
You will need to flash the US Unlocked version of the phone then flash which ever carrier you want.

Just for clarification purposes, are you saying that once you flash the ATT firmware onto a Verizon device that all ATT functions work? Or did you have to also provision the IMEI to achieve this as well.?

sorry for the late reply. But I was able to achieve everything working on my device now. Brief description of what I did to get everything to work:
1. flash unlocked firmware
2. flash att firmware (not unlocked)
3. put sim in another AT&T branded phone
4. Call AT&T have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature
6. DONE you now have a fully fuctional AT&T device, I even got an update from their servers.
I can go into more detail of the steps if needed.

I am looking for the AT&T firmware. I am currently in Kuwait and destroyed my phone. I had to buy an unlocked Note 9 version with the exynos cpu. The problem is I can't WIFI call or use any of the Volte functions my other phone had. Does anyone have the firmware for AT&T? Will that only work with snapdragon? I have already rooted this phone and it is ready to go. I need these functions so I can call back to the States.

Thanks for the quick reply. It looks like I need to wait for Detonator to come out with the AT&T zip. It says coming soon so hopefully soon is in the next couple of weeks. That looks like the best route to go. This is the first phone I have ever rooted. I work with networks and sometimes software kicks me in the butt!

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

I have unlocked AT&T Note 9 but I want to use it on Verizon. I wonder if apply above steps with Verizon will work?
1. flash unlocked firmware
2. flash Verizon firmware (not unlocked)
3. put sim in another Verizon branded phone
4. Call Verizon have them activate and provision everything on account as normal
5. Put sim in note 9 and activate wifi calling feature

Since this will be the 1st phone you'll have rooted, be aware that, especially with Samsung devices, there's a couple of trade-offs that aren't reversible:
1) Samsung Pay will never work even if you unroot.
2) Knox features (I believe) are also a casualty.
There's an e-fuse, for lack of a better word, that once tripped on Samsung devices, cannot be reset. That's why even if you restore the phone to its original condition, those things will be permanently gone.

Thanks for the info. I read up on all of that and the trade off is worth it. I just need all the Volte features and hopefully the correct frequencies for the U.S. I had a note 3 forever and it got destroyed. I loved that phone. This Note 9 is awesome but without being able to manipulate the IMS settings it is a PITA. I just want to be able to call home from time to time. Emailing the wife is no fun especially with the tech available today. I will keep an eye out for Detonator to provide the AT&T CSCs and all that fun stuff. Then this phone will officially be outstanding. I do have to admit that the rooting process was fun. I am all about modified anything. Stock sucks. LOL

Im not a phone guru like others on here. But from my experience that is all I did. A really important step I didn't mention is leave the cable PLUGGED IN when you flash the unlocked software then the locked software. This caused my device to read the "sim info" and provision its self for ATT and get rid of the verizon stuff and install the ATT stuff. Hope this helps you out.

I flashed the us factory on my note 9 from Verizon. I have LTE voice and wifi calling. Didn't trip Knox. No root required. Any particular reason you want tmobile firmware?

Because my carrier is T-Mobile and my Note 9 came from Verizon. Can you provide a link to the factory firmware? Im hoping to flash to factory unbranded, then flash to t-mobile so I can use my video calling.
Thanks for any help
