Hi,
I recently purchased a unlock code from unlockadic for my vibrant but when I went to use it it said Network lock request unsuccessful. Does anyone have any ideas?
If this is in the wrong section I apologize
P.S. I did contact unlockadic and said that this has never happened and that he would have to have his guys look at the problem.
bump because i had the same issue.
you need a non-t-mob sim in the phone for the unlock to activate
I have an account with Rogers & that is the SIM l put in the phone-result was unsuccessful. Code is correct unlock code-i got the same code from three different sources but no luck.

hussafilms is correct.
You need to put in a sim from a network that the phone was not designed for. So if you bought the phone from tmobile then put in a att sim or if you bought it from another company put in a sim that is not from that company. So if you have the galaxy s from rogers then put in a tmobile sim or something.
Let me clarify, I bought a Samsung t959 Vibrant from ebay locked to t mobile and I put in my Rogers SIM card, entered the code and it was unsucessful
How many times did you try to enter the unlock code? I beleive if you have three failed attempts, it will be permanatly locked.
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 an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.
I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.
I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.
Hi. I recently bought the LG V35 supposedly unlocked; however, I am unable to activate on T-Mobile.
Backstory: After purchasing the V35, I followed the instructions on cross flashing to get rid of the AT&T bloat here https://forum.xda-developers.com/lg-v35/development/bootloader-unlock-root-instruction-t4052145. The firmware I downloaded was from https://lg-firmwares.com/lg-lmv350ulm-firmwares/; however, the AIO and the USA versions are both the same. I flashed one of the firmware and all is fine, except now I get "Network locked" after I insert my SIM card from T-Mobile. I went AT&T's site https://www.att.com/deviceunlock/#/https://www.att.com/deviceunlock/#/ for an unlock code; however, I do not get a prompt on my phone to enter the code. This is after I flashed the phone.
My questions are, which version of the firmware was I to use so my phone is network unlocked AIO or USA? If they are both the same, how do I get the phone to be network unlocked so I can activate the V35 to T-Mobile.
TIA

You need to be on AT&T firmware to use the carrier unlock code. If you cross flash to different firmware before carrier unlocking you are out of luck. EDIT: see posts below where new information has emerged.
Obviously your V35 was not carrier unlocked/SIM card unlocked, in spite of what the seller said?
Unlike with the LG V30 series, flashing carrier unlocked firmware does NOT carrier unlock AT&T LG V35. You need to use carrier unlock code prior to cross flashing different variant firmware.
Perhaps you can contact someone with Octoplus box and get back to AT&T firmware to use carrier unlock code. AT&T doesn't publicly release KDZ for their firmware, but some dealers with Medusa and Octoplus boxes still somehow have it.

My understanding is that if you flash the firmware for south america, when you boot it with your sim card, a pop up will appear asking for an unlock code. Haven't done it myself but it sounds like in your situation it wouldn't hurt to try...
Of course, if u don't get a pop up, try the code that supposedly brings up pop up to enter code.
follow this link for the MIA version that should work.
cheers, let us know if you try it the results.
Thread Cleaned and it will end here regarding this back and forth, take care.
Hi OP, use LGUP to flash Mexican region kdz, insert your T-Mobile sim and unlock window will pop-up upon reboot and you can use the unlock code to unlock your phone. Good luck.

Guaranteed? Well, as stated by those mentioning it here, I don't think we've actually done it, only repeating that others say it will work. So again, guaranteed? I couldn't guarantee it, but it seems unlikely that people would say it does work, and be lying about it?
Here's a GDrive link to the kdz you'd want to flash to try it. It's the latest Oreo for the south american region. Aside from using LGUP to flash it, you'd need an unlock code.
The md5 sum from this LG Page should match, to verify legitimacy.
Let us know if it works.

So I just flashed my phone from the link you provided and no dice. I reflashed, factory reset, insert the SIM card after completing set up, insert SIM card after factory reset the second time, etc. with no luck. I am not getting a pop to ask for the unlock code.
EDIT to add: So I found a set of instructions when I don't get a pop up asking for the network unlock code (below)
Second option (device doesn't ask for an unlock code with an unaccepted SIM)
1. Start the device with an accepted simcard (example LG V35 ThinQ was bought in Orange you need to insert an Orange card)
2. Go to the dial screen and press “2945#*model number#” (the same way you enter a phone number)
Example: the device is a P999 you need to enter “2945#*999#” or for KU990 you need to enter “2945#*990#” etc…
So far I am getting closer. Now I get a message saying SIM not provisioned. I will continue to research and troubleshoot. If I continue to run into a another roadblock, I will post here. Thank you all.
Okay, now I fracked up something else. I went from V350EM10h_OPEN_SCA_OP_118.kdz to V350ULM20f_00_NAO_US_
Okay now I am stuck at the LG Life's Good splash screen. I went back to LGUP and did not see it was defaulted to Refurbish going from V350EM10h_00_OPEN_SCA_OP_0118.kdz to V350ULM20f_00_NAO_US_OP_0218.kdz. I went back and reran LGUP with Upgrade chosen; however, the phone is still stuck at the splash screen. Help!

So you've tired to reflash ulm and have an issue there. But did you get it sim unlocked?
here's also some instructions I found re unlocking sim if you don't get a pop-up
UNLOCK LG UNLOCK INSTRUCTIONS
ONCE YOU HAVE RECEIVED THE UNLOCK CODE EMAIL, PLEASE FOLLOW THE FOLLOWING INSTRUCTIONS CAREFULLY.
1) Insert a SIM card that is not from the original carrier in your phone and power on the phone.
2) Once finished loading your phone will ask you for the "SIM Network Unlock PIN".
If your phone does not prompt for a code, please dial 2945#* [model number] # to bring up the prompt
For example LG G4 D851: Dial 2945#*851#
3) Enter the LG Network Unlock Code.
If your phone asks for the "SIM network unlock PIN", use the NCK code.
If your phone asks for the "SIM Service Provider unlock PIN", use the SPCK code.
---------------------
But now you have an additional issue, you say you used 'refurbish' mode for both flashings? To the S.A. one and then back to the ulm one?
To my understanding, that should have worked. But whatever the case may have been, you're stuck now, from what I understand. If that's the case, all I can suggest is trying 'DL' mode for the ULM and select all partitions, OR maybe try 'Upgrade' (if you did refurbish" or refurbish if you did the other.
Sorry to hear you're having trouble, I guess, if you followed the procedure and it didn't work, then this is an indication there IS NOT a way to unlock the sim if you failed to do it on ATT OS.
Let us know if you're able to make any progress / got it sim unlocked or not. We'll have to start relaying the results so others don't have the same issue.

Actually, I was able to get the phone to be network unlocked. I mistakenly went from S.A. version to NAO as Refurbished instead of Upgrade on the LGUP.

Well that's not good. I can only suggest try doing a partition D/L? I don't know if that would help or not, but not sure it could be worse than it is now? Certainly don't try the other options like chip erase etc. Those are not for a situation like this, they will certainly make things worse!

You did not ready the whole thread. I was able to network unlock my device after using a South American firmware. In my haste, I used LGUP and flashed the NAO firmware as a Refurbish instead as Upgrade.
