Hello my friends,
i was in vacation and a I bought a unlocked atrix 4g. My phone have AT&T logo at the back but it is unlocked for any GSM carrier.
OK ! I returned to Brazil and now i want install the homebase ROM.
My doubt is ..... which kind of ROM should I use ? International or AT&T ? I dont know which group my phone belongs. Because it's unlocked but he has the AT&T ROM.
Thanks for the support.
So it is an at&t phone right?
Lets try to find The logical thing to do here...
Its an at&t phone with at&t ROM... Uhm What do you think?

Thanks for your reply.
Yeah, following the logical though I need install the AT&T ROM. But my doubt is:
The cellphone is unlocked and I use it with other GSM carrier than AT&T. If I install the home base ROM for AT&T smarthphones there is some risk to have my phone Locked again to AT&T carrier ? Or, for the reason I have a unlocked cellphone and use it in international area, I should install the international ROM ?
Thanks for your attention
I own an unlocked at&t atrix with my carrier in México wich is Telcel. With an at&t ROM. No problem at all.
Doesnt lock again

The phone won't be locked again once it's carrier-unlocked (sim unlocked).
It's totally unrelated to the ROM you use for your phone. You can install any ROM you like on your phone. This is from my own experience.

Really thanks for the answers!
My logical thinking was... my phone have a different configuration to accept all gsm carriers, and i was affraid to lose that configuration after install ROM's and other things ! A noob doubt ! Thanks for the attention

My S4 is locked to 3 UK.
I would like to flash UK unbranded firmware.
Can I just flash the UK unbranded firmware without unlocking the phone first or must I unlock it first?
I intend to continue using the phone with 3UK. I don't want to brick the phone.
I just want to get rid of as much unwanted junk apps on the phone as I can. I have no intention (currently) of using the phone with any other network.

You can flash any firmware for your variant, and it will still locked to your service provider

And it will not brick the phone?
I was told on another forum that it could not be flashed to any other firmware except 3 uk because it is sim locked.
I just want to be sure before I flash it.

Hello there,
Since the American versions of this phone seem to be bootloader locked, would it be possible to get the Canadian version, on say, Rogers, which isn't bootloader locked, and use it on AT&T? Would I get LTE this way as well? Thanks.
Absolutely. Should work no problem. Just add apn settings and simcard

Sorry to sound uninformed, but what is APN settings? Also, is there a more practical way to get an unlocked version from within the U.S. itself? Such as from T-Mobile?
I sold a Canadian HTC M7 from Telus on the US market with the bootloader unlocked but the new owner could not simply insert his SIM into the phone. It was SIM locked. Locked bootloader is completely different story than locked SIM (the device is locked to work only with a particular carrier's SIM). I had to get an unlock code and then worked. Be aware about this.
Here is your explanation:

Hey Folk,
Will the Sprint variant of the HTC 10 work on tmobile? Thanks in advance!
I am also curious about this!
It will need to be modified, unlocked bootloader, TWRP and S-off. Most likely you won't see a thread for this as the US Unlocked version can work on T-mobile

Hey Schmeggy, can you point me to the modification part? I think all the other parts are straightforward, but don't know what you mean by modified.

You can check here http://forum.xda-developers.com/sprint-one-m9/general/sim-unlock-thanks-to-gcprokey-t3166761 it is' for the M9 and 6.0 A9. No idea if this works for the 10. I have always had Sprint and really don't know much about SIM Unlocking

Hi bro, i have unlocked my 626s in the past with this seller and so i asked him about my HTC 10 half week ago. He told me that he can but that the data would not work and i accepted for 35.00 (phone will be used overseas and they don't care too much about data) checked my SIM with T-Mobile and yes, voice and messages working great but no data. He said he was working to fix it or something (i don't really care now because phone will be in another country on a few days lol)
Didn't find the listing that i bought but find a similar one, but ask him to see if he can help you.

need to unlock in order to use on other networks.
So I have seen multiple people here on the forum claiming to do it or wanting to do it and I am a bit confused. I have an s7 edge on contract from ATT. Can I do this? If I flash T Mobile's firmware on this does this make my phone usable with a T Mobile sim?
Thank you

Can you advise the procedure? I'm currently permanently locked to AT&T network and would like to use a carrier (SK Telecom - Korea).
Wouldn't you still need to SIM unlock your AT&T phone to use on T-mobile network? I don't think just flashing another carriers ROM will allow you to use their network. Am I Wrong in thinking this way?

I had the same question and that's why I haven't done anything on my phone so far. Also it does not help that I am a noob with all these things and dont want to mess up my phone since this is my daily driver.

Go to http://www.cellunlocker.net/ and get an unlock code for your phone. I unlocked my tmobile S7 edge this way right out of the gate worked just fine.

I am confused. Can I not flash the phone with t mob firmware without unlocking? I thought this was just a software restriction and would have been removed by flashing a new firmware.

Flashing the phones firmware will not carrier unlock the device. That is tied to the IMEI. It will boot up the Tmobile software, but it still will only work on AT&T network.
Also in order to unlock the device from AT&T they will most likely bill you for the remaining value of the device as soon as you request an unlock code. You cannot take a phone from one carrier to another unless it is fully paid off.
I have an Unlocked AT&T S7 and I can put in a T-Mobile sim and it works. So why Flash T-Mobile onto an AT&T phone if its Unlocked??? My AT&T S7 is Paid for in Full.
My question is, if you do flash T-Mobile firmware on AT&T phone will you get OTA updates off of T-Mobile, like when Nougat comes out????? Also would you still have wifi calling and get all the LTE bands of a T-Mobile phone????

Yes. All the edge models have identical hardware. Their only differentiating factor is the firmware they run. I flashed the unlocked firmware onto my AT&T model and now get updates directly from Samsung. If you flash the T-mobile firmware on the AT&T device, all features will work and updates will come from T-Mobile. Same would work if you flash the AT&T firmware onto a T-Mobile variant. Or Verizon to Sprint, Sprint to AT&T, etc.

So you are saying this about S7 Edge, does this work the same for the AT&T S7 SM-G930A? Mine is not the Factory Unlocked model but I got the unlock code from AT&T. I thought the firmware came from the carrier and not Samsung on updates on a carrier branded phone???
So if I flash T-Mobile into my AT&T S7, I can also flash it back to AT&T firmware should I go back to AT&T???
Think you are talking about flashing firmware on your that is original for the Factory Unlocked version, think its SM-G930F

Well people on the S7 edge have flashed the tmo firmware on their AT&T models. Updates come from carrier on branded phones. So if you have an AT&T phone and flash another carriers firmware, it would only be branded by the physical logo on the back. It's like buying a Windows PC and installing Linux. The updates would come from Linux, not Windows, and vice versa. You could always go back to the AT&T firmware, just make sure that both firmwares you flash are on the same bootloader version.

But I have always read that OTA updates come from Carrier not from Samsung. Thanks for the info. Maybe AT&T will be out with Nougat by Spring after S8 are out for sale.

Updates do come from the carrier. However, if you flash a different carriers firmware you will start getting updates from the new carrier.

Hi !
I'm a Canadian that bought an "USA Unlocked Samsung Galaxy S8 (SM-G950U)". I love it, but I'm confused about a thing : Why is there a folder called "Verizon" ? If my phone is really unlocked, it should not have Verizon applications on it, right ? And the "region" of the phone is VZW (Verizon Wireless)... Is it normal ?
But, I read that Verizon locked phone are "SM-G950V", not "SM-G950U" and have a "Verizon" writing on the back... Could anyone enlighten me ? Thank !
Verizon phones are unlocked, and support both CDMA and GSM. It is possible that the phone was originally a Verizon phone, but it is still completely unlocked. I wouldn't worry about it
Oh great ! But, is it possible to delete the Verizon applications ? Because I don't need them
