No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.

You can do whatever you want to any rom, and that won't affect anything that makes it unlocked

thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....

is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,

Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Can T-mobile still unlock the phone after I rooted it or would they know that I put a custom rom on it??

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

[Q] AT&T XT1058 can i flash it to a generic rom?

Hi, I got an AT&T XT1058 from ebay. I'm in teh UK so I'd really like to flash it with a stock UK ROM. I've had a look on here and with the huge amount of info I can't figure out if this is possible and which rom to use. it's 4.4.2 that's on the phone at teh moment which i believe can't be downgraded or unlocked easily, is that right?
any help would be greatly appreciated
cheers

To flash any Rom besides the Stock, Signed Moto ROM for your carrier and model X, you need to unlock the bootloader.
While Moto doesn't give out the Bootloader Unlock Code for the ATT USA XT1058, since you have 4.4.2 on it still, you should be able to use Sunshine to unlock the bootloader. (NOTE: please boot into fastboot/bootloader on the phone, and verify the version on the 2nd line is 30.B4 which is correct for 4.4.2).
Once you use sunshine, you can flash 3rd party recoveries, roms, etc.
While I have NOT done it, I've seen posts of ATT US Xt1058 owners flashing with Parts of the XT1053 rom to remove bloat, etc. (flashing the modems will likely change which wireless bands the phone can connect to). I do not advise flashing another carrier's rom. It could get messy, especially around UPDATE time. And I've seen some lose Cellular and WIFI flashing the wrong modem files.
One final thing. The ATT US XT1058 is SIM/Carrier locked too. So in order to use a non-ATT SIM in it you'll need to obtain a SIM unlock code. You should be able to get this from any web site selling unlock codes on the internet.

To unlock the bootloader on the ATT XT1058 Moto X, there are only two possible ways..
The China Middleman thread (in the general section), although he only has codes for certain date range of phones (depends on the Assembly Date of your phone), BUT he has recently stopped responding again. There is no telling if/when it will start up again
Sunshine, which doesn't work with 4.4.4. However you can always try it since it wont charge you if it doesn't work. (i.e. it checks your phone, if it will work, if wont, it tells you and exits without charging you).
4.4.4 can't be temp rooted either.
So you are pretty much stuck stock ATT, and then just get it sim unlocked to use it with your carrier.

thanks for the reply. I guess i'll give the china middleman a try. I'd really like to get rid of the ATT address book, the fact that it perpetually shows as 4g connection and have the phone speak to me in a not american accent!
cheers

the same here
at&t xt1058 with stock android 4.4.4 (ota updated from 4.4.2)
system version 212.44.26.ghost_att.ATT.en.US
build no KXA21.12-L1.26
been using this phone in Europe, Greece with another carriers SIM card
everything ok, except for the LTE bands (in Greece I need bands 3,7,20) and the AT&T bloatware i wanna remove
would like to root, but i'm not able to unlock via motorola's website
let me know if u had any success via the china middleman, or if u find another way
thanks

I'm on Rogers xt1058 (16GB)
Is there any way (assuming I can unlock the BL) to get developer edition ROM?

For the Rogers XT1058, Moto does offer the Bootloader Unlock code for free from their web site -> https://motorola-global-portal.cust...e/bootloader/unlock-your-device-a/action/auth it will void your warranty
The GSM Dev Edtion is the XT1053. It has different radio/modem files, its hardware supports different bands (less LTE bands). I never recommend flashing another model's ROM as we have seen loss of cellular in some cases, where even flashing the original firmware back didn't fix.
Once you unlock your bootloader and root, you can remove and freeze any bloat on the phone (freezing is preferred because the next OTA might require it to be there).

Only if you can't unlock your boot loader. But as I said, moto does give out the unlock codes on their web site for the Rogers xt1058
Also, without unlocking the boot loader, you can only flash the rom for your phone model and its carrier branding.

I see
Thank you for the answers
I knew the second part, was not sure about the first one.

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!

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

Yes, you should be seeing a "enter code" sim lock screen. T-mobile uses a unlock app. if your phone was unlocked before on t-mobile it can be unlocked after you flash back to t-mobile firmware.(and may need to run the unlock app).
I have gone back and fort on 2 of my SM-G920T phones between t-mobile and other firmware including the metro PCS SM-G920T1 one so it should work to go back.
Sounds like you need to re-download the stock t-mobile firmware and flash in odin.

99% sure will be locked again once you go back to t-mobile as they use an app to authenticate.

If it was unlocked before on t-mobile you should be good. most you would need to do is run the t-mobile unlock app. just make sure you have a twrp backup just in case you need to go back to the rom that is working.
