I'm on Eclair (2.1), rooted, got the unlock code for my phone. But since I didn't have another network sim card at the time, I tried the "re-lock" method to unlock. Seemed to work at the time. (Didn't know that this method just adds another "accepted" sim card to the internal list.)
Just got another carrier's sim card, and when I put it in and booted, it did not ask for the unlock code. Voice calls work, but the "Network Lock" is still "ON". I've tried "re-locking" to several other MCC/MNC codes, but I never get the unlock prompt.
Does anyone know how I can force my phone to ask for the unlock code?
Or, how do I turn the "Network Lock" off?

Use http://www.communityhosting.net/sgsunlock/
You don't need to use a different sim.. The Network Lock becomes OFF for any carrier.. After unlocking, check by *#7465625#.
Hope this helps.
Worked, thanks!
Worked like a charm.
One question though: If I load a new ROM on, will I need to do this again?
Or can I just re-copy the nv_data.bin file (if necessary)?

Hey everyone,
I recently wiped my captivate clean. I have used the Odin one click downloader to take it back to Eclair (JF6) and master clear to clear all the files.
I need advice at this point on. I leave for Spain in 5 days. I need this phone unlocked to use my international sim card. Do I upgrade to 2.2 and work with the fact that the unlock code on 2.2 has been erased? Should I stay with Eclair and use easy unlock and root methods?
Any help is appreciated. Thanks.
once you unlock your captivate it will be unlocked for good. Having the stock JF6 rom just makes things easier because the unlock code was in plain text in /efs/nv_data.bin and can be easily extracted. Any rom after JF6 had nv.data.bin file encrypted but there are other methods to get the code.
Try using the Galaxy_S Unlock in the app market first to see if that works if not there search the forums for another solution.

I unlocked it and successfully upgraded to 2.2 froyo without losing the lock. This is great news. My only concern is that when I insert the unaccepted sim card (international), won't it request a code or will it not?
Thanks for the help!
not sure about using a sim from spain but i've used and tested my captivate on:
US T-mobile sim
UK T-mobile sim
US Simple Mobile sim
and Hong Kong sims
without any problems.
open up your phones dialer and enter *#7465625#
if you see:
Network Lock [off]
Network Subset Lock [off]
SP Lock [off]
CP Lock [off]
you should be good to go.
Your best bet is to contact whatever provider you will be using while in spain and ask if them if your unlocked phone will work with their sims.
Thanks for your input. I contacted them and they said their sim card WILL work, just going to have a hard time unlocking it. The good thing is I have done that already!
My network lock is [off]. I thought I would still need the code? I suppose not.
Hi,
I have HTC one on Three UK network. I took Sim network unlock code from 3 different paid servers, All have given same code but code does not work. It says Sim Password incorrect. Spoken to supplier and he said it is some bug in new android system. Can anyone explain me how to fix this. I appreciate that.
I already 3 tried another source and checked imei etc.

Are you on a custom CID ? On a custom ROM? If yes, change them back to the original and it'll work.

This is purely anecdotal but the phone I had before this was the s2 LTE model on AT&T, when they gave me the code it kept saying it was unsuccessful until I ran out of attempts. However when I actually put in a t-mobile sim card it worked fine and it was fully unlocked. Maybe try that?

You do know that to unlock the phone you need a SIM card from a different company inside the phone so that it asks for Network Unlock Code... SIM Lock is not the same...

Obviously phone is asking for sim network unlock code when we put non accepted sim card. So phone is not unlocked. We do quite a lot unlocking and few phones get this error, we have to refund customer but I am seeking solution for it. It is only in Android phones (HTC and Samsung).. Samsung's we usually unlock using unlocking boxes but HTC One is not supported other than code. (Setool support older HBOOT).
In an attempt to use my locked AT&T HTC One phone on my T-mobile service I used the Cyanogenmod Installer to root my HTC one and hope to use it on the T-mobile network; I also unlocked the bootloader via HTC website. The newest Cyanogenmod is installed (11-20140417-NIGHTLY-m7) and wifi is working, etc. Unfortunately, no phone calls since it keeps asking for SIM Network unlock code (I bought an unlock code...not working). Any suggestions? What should I do? I did some research and I read something about using an RUU...is this a good solution? Thank you all!
Status of phone on bootloader screen is:
S-ON "TAMPERED"

No luck the phone they're referring to is the HTC Amaze it seems.
Does successfully installing Cyanogenmod "unlock" the network as well??

No, bootloader unlock and sim unlock are different things. You'll need to be on the stock rom to input your sim unlock code.

And that's what worked. Thanks!
Hello,
I (still) have the same problem here. I have a DHD that was locked and branded. I followed HTCDev's procedure to unlock the bootloader and installed a Cyanogenmod ROM (unofficial 10.1) two weeks ago that works great. I've been trying to get my phone unlocked for days with no luck ever since.
I've tried using the HTC unlock tool v. 0.9.5/4 and rooting the phone too. Nothing. Drivers are working fine; program executes as expected, but I still have a locked phone after it finishes. I got an unlock code that I enter after booting and I get a "successful network unlock" message, but the radio seems to remain off. I cannot place calls. Attempting to choose a network operator manually from the settings menu fails; I get a "mobile network unavailable" message when doing so (service providers list does not even appear). I've read threads saying that the only way to get around this is by reverting the phone to its original ROM and HBoot, but I've read elsewhere that workarounds on branded phones shipped with Gingerbread or Froyo (like mine used to run) fail and/or screw up the phone, so I have not tried that. Any ideas or pointers?
Thanks!
Hi everyone. Could someone please give me the dial prompt or another method to enter an unlock code? I bought an unlock code but can't find a way to enter it. I've also tried mayrer's method (here: http://forum.xda-developers.com/spr...sim-unlock-t3229801/post63465284#post63465284) to sim unlock without codes but it didn't work, unfortunately.
When I put an unrecognized sim into the phone, it tells me it's an "invalid sim" but it doesn't go to another screen to enter any codes as I've seen in some videos.
Any help would be appreciated!
Edit: I have the the ls991 zv5 5.1. Flashed to stock and rooted. Trying to get it to work on Orange network in Spain.
Hi everyone,
I've been using an SM-920T 64GB Galaxy S6 bought from T-Mobile last summer. I did a permanent unlock using the T-Mobile application and since July I've been using the phone on the AT&T network. I just rebooted my phone today like I always do and upon restarting I got an "Invalid SIM Card" and it brings up a SIM network unlock PIN window that I can dismiss or enter a code into. What is going on?
I'm running XtreStoLite Deo 2.4 if that makes any difference.
Also, does anyone have the T-Mobile Device Unlock apk that comes stock with the phone? This is how I unlocked the phone in the first place but I don't have that app anymore since I run a custom rom, and the play store won't let me download it because I don't have a t-mobile SIM card in the phone.
Thanks!
Well for the benefit of whoever has the same issue. I flashed back the stock ROM via ODIN, ran the T-Mobile Device Unlock app, it said Unlock Unsuccessful in big, but right below it said the phone has been unlocked permanently. I put in my AT&T SIM and it was working again. Then I flashed back my TWRP backup and the phone remained unlocked. The non-Tmo ROMs get the unlock popup when a foreign SIM card is inserted, so getting an unlock code should work, but I didn't want to wait 3 days to receive one.

Can you tell me what ROM you used? I have the g920T also, and bought it USED unlocked from ebay, but it had the FRP (factory reset protection) lock on it. I had my US cellular SIM card in it, even though I was stuck at the "enter your previous used google account on this device" and the SIM seemed to work (saw the LTE bars above).
But the only way for me to bypass the FRP was to flash to the ROM to stock (which I used the G920T tmobile ROM) and I got to the home screen but now it says "Invalid SIM card. Network locked SIM card inserted" just how you were saying.
When I try using the Tmobile unlock app, it says "Server not responding. Please try again later." .
Please help!
