Do I have to unlock my device everytime I upgrade firmware or change ROM? I am playing around trying to find the ROM I like most. But don't want to Root, and unlock after.
unlike the iPhones, your i9000 will remain unlocked once you've unlocked it. Firmware upgrades are for legit reasons, not just to lock your phone down again.
Rooting is affected by firmware upgrades but is easy to fix.

So...
If I make a nandroid of my current rom (Vodafone Spain stock Rom).. will this "save" the lock/unlock status, or is the status NOT depending on ROM?
I need to know this because of warranty .
Thaaaaaanks...
Hello All;
I am using my AT&T Captivate on Canadian Rogers network with a seller supplied unlock code, as well as a "sgs unlock.txt" file in my phone.
If I ever do either OTA upgrade to Froyo, custom leak upgrade to Froyo, or any kind of flashing such as stock ODIN and such, will the unlock code ever change or can I be using the same unlock code, if the phone ever decides to lock itself again?
Cheers!

Hmmm....good question. I thought i read somewhere in these threads that when you flash ANYTHING (beyond eclair/ jf6 build), that you do lose the unlock code. I could be wrong. These are one of those times that i wouldn't mind being wrong. lol
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!
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

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 !

How did you solve this? My phone stopped working flashed newest (G920TUES5DPK1_G920TXAR5DPK1_G920TUES5DPK1_HOME.tar.rar) and i can't go to older version as that gives me ;
Code:
SW REV. CHECK FAIL DEVICE: 5 BINARY: 3

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

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

Have you tried with the tmobile device unloced app.? If that doesnt work then head over to this awesome guy, he can help you unlock it remotely. https://forum.xda-developers.com/tmobile-galaxy-s6/general/sim-unlock-honestly-free-t3601740
Hi. I have a Samsung galaxy note 3 and it rooted. After the root I wanted a different service so I have t-moble. I downloaded the region lock away and went through the steps. After my phone was rebooted it still ask me for a unlock code after installing the region lock away. The note 3 is a att phone. Need help
What rom is on the phone? I believe region lock away will only work with certain modems.
I don't have safe strap installed with different roms. It's the original rom and the phone is rooted
If the rom is too new, I don't think region lock away will work. For example, the s4 the modem must be 4.2.2 with root before region lock away will sim unlock the phone.
Oh ok. Well I'm 5.1 android version. Is there another way I can do this instead of paying for an unlock code?
The only way to unlock would be to get an unlock code. If you're not on ATT and the phone is not blacklisted, maybe contact AT&T.
