Guys
I've searched the forums and realise I can buy a SIM unlock code for my Blackstone, however I'm trying to clarify the following.
1. If I install a different ROM do I still need to buy the unlock?
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
Thanks in advance for the help.
Regards
Its an unlocked phone my friend so obviously you pay a higher price for the phone itself able to use with any sim card. Carriers phone that are branded with the carrier logo are usually cheaper with a plan that could cost more then the phone overtime and is locked to the phone carrier which requires a sim unlocking code to use with other sim cards/ other carriers.
The answer to that is you can install any rom on the phone and if it an unlocked htc touch hd which you paid a lot for then it will be unlocked forever
if its locked to a carrier im not sure about that maybe someone can clarify.
any ideas please guys, I get the phone in a couple of hours.

Anyone?
Try to keep this short
1. If I install a different ROM do I still need to buy the unlock?
No Simlock is based on the radio and hardware (short version).
Once unlocked yoiu can up your rom and your radio, it stays unlocked.
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
Got me lost on this one.
Simlock is based on radio and Hardware.
So your IMEI is part of the phone which is either Sim Locked or not.
If you put your sim into what ever is in phone is in your car your number will be the same.
Once you have sim unlocked a device it remains unlocked.
Like I said you lost me.
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
No - Once done it remains unlocked regardless of rom or radio upgrade.
(and if you buy a new Simlocked Blackstrone you cant use your old code as the lock is based on the hardware)

--->point me to the page that you feel needs updated, i will have a go at it.
(please PM me)
Ok.. sooo.. Some people have gotten the JIC ota update from tmobile USA.. Well i decided to go ahead and update it. Well I lost the carrier unlock on it now.
I was just the stock rom on it rooted and unlocked using the one click unlock to get teh codes to unlock the phone. It worked then. Now with the JIC6 update i have lost that unlock. Also the one click unlock app to get the codes no longer works. I have also seen other post about using a hex editor to look at the nv_data.bin file to look for the unlock codes (no success). I have the original code from before the update, but it does not work. Is there a Way to unlock the vibrant with the JI6 update?
Just enter the same code you got last time. and it will unlock you.
If anyone else reads this. Please keep your code. and put it someplace safe. everytime you flash you will need to re-unlock most like a iphone.
Interseting that i didnt even have to reenter it. First when i updated and than checked teh network lock code showing that it was on so i than proceded to use the one click unlock app and it didnt not work. SO lucky for me i have a screenshot of the code when i first used the unlock app. so i did the same process and put in another carrier sim and entered the unlock code. It told me it was unsuccessful. Now that i went to try it again after my first post. I procceded to put in the other carrier sim card and it was unlocked.
Oh well. Thanks!

He says in the OP that he has the original code, but it doesn't work.
I know this is actually a known Samsung problem that has happened on many of their phones (even ones that came unlocked from what I've read) & generally re-entering the key works.
If it doesn't work for me, I'll call up TMO & complain. I bought the phone at retail price off contract, so they should give the code w/o a problem.
Generally as long as you've been a customer with them for at least 30-90 days (and your phone is beyond the returnable period), they'll give the unlock code if you call & ask for it. Sometimes you have to say that you'll be travelling out of country in order to get them to give it to you.
Is there a way to unlock without putting in a foreign SIM?
WTF !
Do you mean that updating the device to JI6 will lock the phone ?!
I unlocked mine with a code is that means I'll lose the unlock ?!
I discovered this a few weeks ago. I was working on a fix when I bricked my phone.
I just got my replacement on Tuesday and will be continuing the fix.
What happens is either something within the ODIN process, or on the rom itself puts a generic bml3 block on that contains all F's where the unlock code is stored.
I also know that it's stored on the nv_data.bin in the ./efs block.
I have been able to get my unlock code to be seen by the sgux program when modifying the bml3 file and pushing it back to my phone.
I will be working on nv_data next, though, seeing as my new phone has the unlock codes already, I'll have to do some editing and backing up.
I have my old codes with me so can someone confirm if old codes still works after the update ?
Thanks for sharing the information with us regarding phone. It may help us n the future.

Yeah after my original posts i think your old code will work. It will probably give an error of that it was unsuccessful. Just ignore it. and and just reboot the phone.
so basically to recap what i did.
updated JIC6 ota with tmobile.
checked network lock *#7465625# ( showing that the network lock was on.)
tried that software one click app to get code. (unsuccessful)
powered off phone
put in another carrier sim card.
bootup phone.
put in old code i had from before update to jic6 ( says that it was unsuccessful )
power off phone
put back Tmobile sim
power off phone
put other carrier sim in
unlocked!
i dont have tmobile sim ...do you think it needs that ?
I ran into this on my old vibrant running jfd. Unlocked and rooted and I needed to reflash jfd with odin. Phone relocked itself even reflashing same firmware. Efs data didn't change because the unlock code could still be retrieved. But when I inserted my att sim the code unlock said unsuccessful no matter what I tried. It never unlocked again.

So old codes didnt work for you and you are stuck.
can anyone confirm if we should update or not to remain unlocked ?
anyone confirming this ?
I got two different statements here
Ok, I updated my vibrant to JI6 today and it didn't lock my device !!
Since I don't use T-mobile data plan so I downloaded the leaked rom from (Vibrant Android development) section then I flashed the stock rom followed by JI6 ROM and it's working perfect !!
Maybe because mine is unlocked officially by T-Mobile code !
Or may be only ota is locking
We need more info

Now time to check whats new :d
They will not release a code nor will att for 9 months after the phone is out. You may call and ask.
Thats why i offer unlock services for these phones.
Successful OTA update yesterday, NO NETWORK LOCK, phone was rooted with no lag fix
Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.
I think you should visit :

So apparently all you need to do to convert your phones firmware from Sprint to T-Mobile is flash the stock BQK5 firmware (acquired directly from Sammobile) using Odin. After unlocking my sprint phone, I flashed this firmware with a T-mobile Sim installed. The phone booted up and upon it showing the home screen, shortly after it said something about it needing to restart and configure what I would assume is the newly installed T-mobile Sim. The phone booted, and all of a sudden instead of seeing the normal sprint boot sequence, I saw a T-mobile one instead. It caught me off guard because on my screen was Juvemex method of converting an S8 to any carrier firmware. I was both relieved and sad that I did not have to use Juvemex guide. Hope this helps anyone trying to convert their phone from Sprint to T-mobile. Obviously I have not tried that with any other carrier so I can only confirm this works on a sprint phone using the Sammobile firmware flashed with Odin. Good luck and let me know if this method works for you, knowledge is power:highfive::highfive::highfive:
How did you sim unlock your phone first?
I went to a 3rd party site and had them remote into my computer and perform the unlock. Unfortunately due to Xda rules I cannot advertise who it was specifically but I can say a general search on eBay does advertise the same type of service. Once that was done I did what I mentioned in the OP and my phone turned into a T-mobile one. It initially booted sprint which was obviously expected, but then it asked to reboot and then viola, T-mobile stock rom since
So i have the smg935p but i am new to flashing roms and have been learning trial and error. I initially flashed a custom rom to the 9bit amd essentially soft bricked the phone. I did more research and flashed the stock rom(or so i thought) now my software version is G935AUCU8ARJ1. I have since had the phone unlocked by spint but now every sim i put into besides the original is showing invalid. Any ideas as ti what i can do about unlocking this phone to any carrier? I am currently using straight talk which i never wouldve switched if id known about the hotspot issue. Also if anyone knows how to bypass that issue that would also be wonderful. Can i perform this unlock or task of doing such without a computer?

If you previously owned it, you can try contacting Sprint to get it Sim unlocked. You might have better luck finding an unlock service on eBay though
