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

Updated mine through odin.. still unlocked.
thanks...i just updated with odin and mine is unlocked
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
i have question that might be little od.
my motorola defy was soft unlock, i installed a custom rom in it and now it is again asking for SIM network unlock pin.. and i can't software unlock it because i am not that good in it.
i found a person who is having exactly same t-mobile motorola defy and it's also software unlock running in stock 2.2 froyo.
if i take a backup of that phone, and restore it in my motorola defy.. will it be unlock again ??
Hi,
I have a Defy MB525 on T-Mobile running CM 7.2. The phone is getting old and has some hardware problems, so I bought a more gently used one on eBay. I've rooted the new one and successfully installed Bootmenu, 2ndInit, and CM 7.2, but when put my SIM card in it, it wants an unlock code. I tried the soft unlock method discussed here, but no success. I then tried the troubleshooting recommendation involving airplane mode and terminal emulator, but that didn't work either. I then got the idea to backup my "old" phone and restore it to the "new" one, and that went smoothly, *BUT* while I no longer get prompted for a SIM unlock code, there is an "x" next to the service bars and the phone indicates "no service." Both old and new phones have EPU93_U_00.59.01 baseband, old phone does get service, while new one does not. I'd love to hear any advice people may have. Oh, new phone was on Moviestar service . . . sorry for the stupid question, but when I've been prompted for a SIM unlock code is it Movistar's unlock code that I'm being prompted for or is it T-Mobile's? I assume that SIM unlock code is associated with the phone and not the particular SIM card itself--is that right?
Thanks,
Doug
I guess what you need to do is install Baseband switcher 4.1 or 4.0 and configure it so it grabs the correct baseband
As of this point the warranty on it has long since expired (for both Motorola and Target, the place where it was purchased) so we're pretty much willing to try anything to get it working
I've got with me here a G5 Plus XT1687 that, at best, I can describe as being in a state of "limbo". Its bootloader mode can only be set to flashing_unlock and flashing_lock. We've obtained the unlock key from Motorola's tool and have tried fully unlocking the bootloader multiple times following the guide on XDA, but it seems to not want to accept the command fully and remains on flashing_unlock. When I try to relock everything to start over, it gets stuck on "flashing_lock" and won't go back to fully locked. When it's in the flashing_unlock state I am able to flash ROMs and TWRP builds, so technically it's unlocked.... sort of. I'm unable flash SOME things, like new bootloaders or gpt partition tables, but other things will work just fine, albeit with the occasional "invalid signature" message following flashing. But this right here is only the start of our problems.
Having purchased the US retail XT1687 model, it was supposed to come carrier unlocked out of the box. My friend who got this didn't have a SIM when he got it at the time, so he just used it as a WiFi-only media player sort of thing. When he finally got a T-Mobile SIM and put it in, it asked him for an unlock code. This of course doesn't make any sense, because we didn't get this from a carrier, so why would it be locked to anything in the first place. It was tried with multiple different SIM cards, running multiple different ROMs (and even stock firmware) all with the same result: the phone seems to be network locked to nothing at all.
I tried calling Motorola and they said they can't make an unlock code for us since it's the carrier that decides what algorithm to use for network unlock codes... but this phone didn't come from a carrier, so I don't know what to do.
Fixing the bootloader thing would be nice, but my main goal here is to try and remove this nonsensical network lock so my friend can actually use it with T-Mobile. At this point he doesn't want to send it back (since we'd have to pay for the repairs, and he got a cheap LG to use as a primary phone anyway). That being said, we're pretty much willing to try anything to get it working. Any suggestions?
EDIT: just want to mention as well, we've never had a problem with the IMEI being set to 0. It's always been what it originally was
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
