Ok, I'm a noob, but I do not hate myself, and I have done a search for similar threads. None apply.
Here's the situation:
I received a used Samsung Captivate with Gingerbread on it from a co-worker, who upgraded to a Galaxy SII. He erased all his personal info/data, but I don't have the details.
I called AT&T, since I'm a customer in good standing, and since the Captivate is not subject to a contract. I asked for an unlock code. They gave it to me. I put it in the dialog, and it did not work. I got something along the lines of "Network unlock unsuccessful. You have 9 attempts left." Not the EXACT wording, but it gets the point across. AT&T and I checked and re-checked the IMEI, and they kept generating the exact same unlock code (which is 8 digits).
In all, I've spent 3-4 hours on the phone with AT&T service, and about an hour with Samsung service, which is where AT&T sent me after they couldn't figure out why the phone wouldn't unlock.
With one attempt left, Samsung said the phone needed to be reflashed, and sent me a UPS label to send it in. So I did. They replaced a component by the power port, reflashed, and sent it back to me. So, stupid me, I tried the unlock code again, after twice again verifying the IMEI. Now, the phone says "Network unlock PIN number is entered incorrectly. Contact your Service Provider," when I put in a T-Mobile SIM to test. (Yes, I know I can only get EDGE on the Captivate on T-Mobile.)
I called Samsung, and they said they don't know why it wouldn't work, and that the unlock code was indeed correct, and that the mainboard probably needs to be replaced.
Has anyone ever heard of this? Does this sound logical? Am I dead in the water unless the mainboard is replaced, unless I want to use AT&T exclusively? I had hoped to be able to use a foreign SIM when I go out of the country, but it looks like this is no longer possible, unless the mainboard is replaced.
An AT&T GoPhone SIM works just fine.
Thanks,
Tracy
What happened most likely appears to be a miscommunication. Do you know what excatly they flashed ?
Personally speaking, without going through AT&T route, I myself have used the Galaxy_S Unlock by Helroz which works like a charm. ( you need to be rooted though)
They flashed Froyo 2.2 I897UCKB2. I was considering rooting and flashing a new ROM, but having searched for unlock info before calling AT&T, I learned that in Gingerbread, they hid the unlock code. Thus my reason for calling AT&T (since I didn't want to pay for something I could get from AT&T for free). I'm glad I didn't do any rooting or flashing before I sent the phone back to Samsung. I have NO problem experimenting once I either: 1) know for sure I can never unlock the phone, or 2) can successfully unlock it. I don't want to have to undo a bunch of stuff before I send it back to Samsung. I'm lazy.
From what I was told by AT&T and Samsung, once you've used up your attempts, you're permanently locked to the original network.
Thanks!
About I guess 6 months ago there was a little app that would let you root your phone temporarily. It stayed rooted until you reboot. It worked very well. I used it a lot until I rooted my Captivate for good. Unfortunately I can't find my copy of it. I did a quick search here and didn't run into it either. It may be worth a try if you can find it.
If you root the phone, unlock it with the the app mentioned before, then do a factory reset, you will no longer be rooted, but the unlock will be there. Once you unlock a phone, it stays that way unless you decide to relock it. When you unlock the phone, it will put a folder on your phone. Keep that folder in a safe place. Just to be safe, copy and save it in multiple places. If you ever want to relock the phone you will need that folder.
Cool, thanks, guys. I'll look for the app and try it out.

My wife and I just switched over to t-mobile about a month ago and at&t wasn't much help in getting our phones unlocked either. The gave us unlock codes for some other phone.
I used the same app that theevildevil mentioned, Galaxy_S Unlock by Helroz on my phone. On my wife's phone I used Samsung Galaxy S Unlock Tool by DaGentooBoy. Her phone was running a gingerbread ROM. Mine even had a screwed up IMIE number. Both apps worked great though.
ZeroG1, how many digits were your unlock codes? I ask because Samsung thinks AT&T gave me the number for the wrong thing.
Thanks,
Tracy
Hi guys, noob here, but not so noob on android OS
I was trying to unlock my verizon droid 3. And when I´d inserted a sim from another carrier, it just says "subsidy lock, call provider".
How can I make the phone ask for the unlock code?
I read somewhere that this message appears when you tried too many codes, but havent tried anything. I read that this problem was solved on other moto phones by leaving the phone idle at subsidy lock screen for 4-5hs and the phone will ask again for unlock code, but thats not the case
Anyone experienced this problem?
call verizon tell them your going our of country on a business trip and you have a european SIM already that you would like to use, but you need to unlock your phone. viola
Im already outside US. Problem is phone dont ask for unlock code.
Alltel or Verizon Wireless do not use any type of subsidy locks on their CDMA phones. Default Code:000000 or 123456 or 654321
that is what i found by looking up the subsidy lock error you described. tell me what happens when you input one of these. im still doing more research for you
Hi, it just says "subsidy locked" and a discard dialog box, there is no box to enter any number
Phone is dual cdma/ gsm 3g, Im trying to unlock the sim part.
I´d read this forum.xda-developers.com/showthread.php?t=1406812 but Im missing the enter code dialog box
the fact that their is no dialog box is weird to me. can you press the menu key? does anything pop up? i googled this but did not find anything. ima check some other sites. do you have an account with verizon?
Yes, phone was working on verizon till the day I leave my city.
The only option when I put a foreign sim card... it´s just the subsidy lock legend and if I hit the discard dialog box, phone goes to android home menu. But obviously with no gsm signal.
I can do everything, flash, root, everything. The only thin I cant do, it´s downgrade, phone was updated to last verizon 2.3.4 OTA when was connected to verizon network, and as other thread says, it´s no downgradeable atm. Im thinking that verizon could have put some newer simlock protection to latest updates...
since subsidy lock is simply by the carrier you can contact verizon and they can tell you what to do. if you dont have anyway to call the usa, you should email them.
Well... more news. Contacted verizon tech service and they teach me how to get to the unlock screen. But for the code I have to wait almost 6 more months.. lmao
Well... more news. Contacted verizon tech service and they teach me how to get to the unlock screen. But for the code I have to wait almost 6 more months.. lmao
At least I can try any code now
sorry you have to wait. i should have said there is a certain wait period for each person [i think 10 months] before their eligible for an unlock code. butttt you can always get one online. glad your initial problem was solved though
Yep, thanks for helping. Maybe Ill try some online code but I think they wont work
If anyone is experiencing the same problem, the only way to get the unlock code input screen is setting to only gsm mode and then turn on/off airplane mode a couple of times and magically unlock dialog box will appear.
there is one that works. ima go find which forum i found it in and post back tonight. probably within the hour. well i cant personally garuntee it works but it had good reviews from xda memebers
That would be nice In case you dont want to post link here, just send me a pm
I have to do some things for the rest of the night and its too much too look up on my phone. If I don't get on again tonight I always check xda whe n I wake up so ill have it first thing tomorrow morning at the latest
Sent from ICS Droid3 using xda premium
Maybe share what you did to get the unlock code dialogue to open. Save others the time of having to call Verizon themselves, since you already did that
Why do you have to wait six months? Was your line on Verizon too new to get an unlock code?
Droid 3 with stock xt862 ROM working on T-Mobile via xt883 radio.img & custom build.prop
Yep, first rule on a forum: dont say it works, say how you make it work
Its a couple of post above, set only gsm mode, turn on off airplane mode a couple of times, and unlock dialog will appear.
I'd unlocked other phone some time ago on verizon and for the next one, I have to wait half a year
Anyway Im not coming back to states anytime soon, so I'll have to throw it through a window
Btw fisrt ebay code didnt worked.
My bad, didn't see this whole second page when I was on mobile lol. Second rule on a forum: read all posts! Good luck.
ebay switftunlock freedomobile and unlock_fusion
whichever you choose and they can send you and unlock code. these are based on reviews from this forum
Thanks, I´ll try one of them
Hello. I ordered from Amazon.com a used Droid 3, which used to be on the Verizon network. I am in Peru, and was planning on using the phone with a SIM card on the Movistar network. Powering on the phone with the SIM installed resulted in the phone asking me for "SIM network unlock PIN" I thought it was the SIM PIN, so i tried that a couple times, no no avail. Then, I found online that the default PIN is "000000" or "123456" so I tried those, at which point my phone came up with the message "Phone is subsidy locked" (or something to that effect)
I called Verizon in the US, and the tech support guy said the phone shouldn't be locked, and that the EMEI isn't on any lost/stolen lists. Am I now stuck with a $50 paperweight? Can I unlock it or root it or reflash it in this condition? Right now, I have the SIM out and I can use it on WiFi and download apps and stuff, but it is basically useless as a phone at this point.
Any help would be much appreciated. Thank you.

Thought I would reply here too, in case someone thinks about trying to help. I replied to your thread on a different site. You have sent phone back, so there is nothing left to try, at the moment.
Thanks for getting back to me. I still have the phone at the moment. I have until Saturday to figure it out, otherwise I'll send it back to the US with my MIL. Please, do tell, what's your secret?
Also, what site did you reply on? I've been all over the Motorola pages for the last week looking for solutions. (I solved the MB508 issue, so I don't have to send those back.)
No secret, and no fix

Oh well. Thanks anyway.
I had gotten a T-Mobile Galaxy S6 off ebay (refurbished), and I'm not a US resident. The phone and network worked perfectly fome until today, two days after the nougat update, the phone automatically restarted and said that my device is network locked and it can be unlocked using the Device Unlock app. Now when i opened the device unlock app it stated that my device is not elegible for unlock. What should i do now? There is no chance of me going to US or any way tgrough which i can send this phone back to US. Is there ANY possible way in which this can be unlocked? Additionally, the IMEI has changed I guess, the IMEI on the back is different from the one in the *#06# menu. Is there any way to restore the network on this phone or am i stuck with a $250 brick?
Same thing happened to me. I know the person who I bought it from, she has called tmobile and requested another unlock to be sent to the phone, aftet 48 hours they just sent an email saying the device can only be unlocked through the app. Have you found any resolution? I'm thinking we'll have to downgrade the software somehow.

First check your IMEI if its changed you'll have to get it fixed by Z3X box, I got my phone fixed through Z3X box, you can't fix it yourself, and after the repair I had to stay on Marshmallow as the latest update at that time (a month ago) didn't support Nougat. Only unlocking the phone won't fix your issue, it'll keep showing (Searching) in the network name.
I appear to be in one of those samsung lock horror stories. I purchased a paid off verizon s21 ultra that was suppose to be unlocked but after i put my tmobile sim into it works for 5 minutes perfectly then an error pops up saying unable to change carrier call verizon customer support. So i did long story short i got no where. So i filed an FCC complaint and got in contact with a verizon executive and he got in contact with who i bought the phone from and they provided all the paperwork proving it was paid off and he reprocessed the unlock request and said it will now for sure be unlocked and it didnt unlock so i contacted samsung like he said for me to do if it didnt so i did and they told me to wait 48 hours for it to process. 48 hours later guess what its still not unlocked so i call samsung back and they said verizon still hasnt released it supposedly and there is nothing they can do and i need to go back to verizon. Im stuck in an endless loop of verizon executives telling me to call samsung and samsung telling me to call verizon.
What is there left for me to do now? This is stupid why is it not unlocking... The only thing that i can think is left is that the phone is flashed with stock firmware and not verizon firmware to remove the bloatware. But that seems like it shouldnt matter. Also the phone never asks for an unlock code it just says call verizon customer service.
It's more a Verizon lock horror, not Samsung.
Flashing other FW won't solve your issue.

First, did you verify that the unit is paid off?
Second, do you know anyone that has verizon?
Don't know if it will work, but I would try flashing the unit back to stock Verizon firmware and finding someone who has a verizon sim card.
Verizon units kind of unlock on their own. It is troubleshooting I would try because I do not believe the unit will unlock on U1 software on its own. Once it can get unlocked then flash back.
I suggest someone who has a verizon active SIM as it may help in it unlocking even though you can connect through WIFI

The verizon executative said it was guaranteed paid off and he unlocked it remotely again. But it does have u1 firmware on it im guessing i need to use frija and download the vzw firmware? And will another unlock request need to be processed again? And none of my friends have verizon due to how much of a ripoff they are lmao but i can have another verizon demo sim put in at another verizon store. I feel like i would have to file anpther fcc complaint just to talk to another verizon executive.

I believe for it to be unlocked or at least go through the process, the verizon U package is what I would flash, but you may be in a little bit of a issue if you don't have a verizon SIM on hand, even if not activated.
There are multiple ways to get it to flash back to U. I would use a patched ODIN and just flash the appropriate files from somewhere like samfw.com
If he sent out the remote unlock, it is very possible that once you flash back to U verizon package and connect to WIFI and go through the setup process etc. It may just unlock on its own. If you do not have a Verizon SIM card, leave your SIM out of the phone while going through the initial setup. You will need WIFI.
I would start with a clean flash just to be safe.

You literally quoted the answer
Verizon firmware has an app called "Network Unlock". Perhaps at the 60 day mark, the phone automatically unlocks. However, if on the unlocked U1 firmware, there is no framework to remove the lock. It'd be interesting to see exactly how the Verizon unlock process works.

It is somehow tied into their U package software and I am assuming unlocks it at the modem level in background processes. It's like the "signal" they send out can only be detected on their U package. I've seen it many times where Verizon phones automatically unlock themselves when restored to original package from U1.

I can confirm this works on my s21+ that was on verizon network, and was supposedly networked unlocked. Service carrier software said vzw/vzw, vzw/vzw. Tried to switch to tmobile with no luck with sim card swap. 5 minutes, error message about cannot which carriers, please call Verizon. Was on SM-996U1. So I tried to flash to SM-996U1 TMB, then SM-996U1 VZW, then, SM-996U1 XAA. No luck. Then I flashed, hesitantly, with SM-996U VZW . I thought that would put all verizons bloatware on it. Reseted phone and it did put all verizon bloatware on it. Then the magic! I installed my new tmobile sim, and a message appeared and asked if I wished to switch carriers. YES!!! phone rebooted to tmobiles network with no verizon errors. I checked service carrier software and it was TMB/TMB, VZW/VZW. I flashed phone again to SM-996U1 XAA. I rebooted and service carrier software was TMB/TMB, TMB/VZW! I then checked for software update, took update, and all it good! Thanks for all the information here. Took me days to find it and understand it and try it!!
Hi, folks. I am facing the same issue with my S21 5G (SM-G991U). I am also told that the phone paid off and clean. I am not sure what version I am on currently. I have tried SamKey, but that didn't work. Any help would be appreciated. Thank you in advance.

From my experience, Verizon phones will not unlock unless on the U package, the U1 never allows the unlock to be processed.

It does not boot up with Verizon but it does have a few Verizon apps included (it has Call Filter and Digital Secure) installed. The current version of the software is G991USQS6EWD5. Service provider version is SQOMC_SM-G991U_OYN_SPR_13_0020 SPR/SPR,SPR/VZW.

Are you using this phone with Verizon service? From info you provided, your phone thinks you are using Sprint. It's a SPR CSC. You need to change the CSC to VZW. You need to bring the phone back to it's original state for any attempt of the unlock "processing".
