[Q] Locked out??

Hi,
First of all I hope this has not been covered, I searched but found nothing.
I recently bought an unlocked Captivate from the US, I am in Australia. I put my sim in and all was good. Used it for about 4 weeks and then one day turned it on and said on the screen 'you have entered an incorrect unlock code, please contact service provider.'
Now I never entered a code or even had a chance to enter a code. Now it will not let me use any sim at all or even give me a chance to enter and unlock code, which I have obtained using the one click unlock found in this forum.
The phone is rooted but was working fine when rooted originally.
Can someone help? I can still use phone with wifi just not sim. I have tried a hard reset and that still has the same problem. I have tried flashing it back to an older rom, same deal.
What can I do? I can't even enter an unlock code to get it unlocked.

All sim based devices have a PUK code...contact your provider, ask for it and then try to unlock your phone till it ask for it...then you can reset it...that'd what I would do.

[Q] I unlocked my phone, sent for repair, and unlock code unsuccessful??

Ok, I purchased an unlock code and unlocked successfully. A few weeks later, I sent out for repair for GPS lock-on issues, and recieved the same exact phone back(s/n and IMEI's match). I am really not too sure if the phone is unlocked still or not but I don't think it is because I cannot delete the T-mobile APN.
I tried to unlock the phone by using the 2945#*999#, but when I enter the unlock code that I have purchased, it says unlocked unsuccessfully.
Does the unlock code change or stays the same always. If it stays the same, why am I having a problem? I tried inputting twice. Please help, thank you.

[Q] T-Mobile's Z3 debranding for sim unlock.

Hi everyone. I bought a T-Mobile's Z3 used by another guy. He shipped it from the U.S but i'm not there. The thing is: He bought a SIM unlock code but T-Mobile won't let me introduce it because they only let you unlock the phone through their app. The question: If I debrand the phone by flashing the global/international firmware would it let me introduce the code? . I hope you can help me.

I don't think you can just cross flash, at least that is my experience with other devices as well. Also no way to bypass the SIM lock as there is no boot-loader unlock or r oot for the TMO Z3.
As far as I know its an over the air unlock and there is no option to even enter a code... when the app did not work for me I called TMO and they unlocked it within an hour, as I am a current customer.

Oh well!. So the only hope is to wait for some root method. Thanks for your answer :good:

Root and bootloader unlock have no effect on sim unlock. They are completely different things

It depends by phone/carrier implementation I guess, for my Sprint LG G2 you could bypass the simblock using a method that requires root. In the HTC M8, boot loader unlock with Super CID could achieve SIM unlock as well.
You probably are correct with Z3 though.

Im in the same boat, bought a used z3 and tried to unlock using device unlock app on phone, Failed. I bought an unlock code but there is no menu to input unlock code. If we flash global generic firmware, will unlock code pop up?

Has anyone tried this and been successful? I attempted it this morning but got errors and flash aborted.
Edit
Guys keep trying the unlock app. I almost gave up and tried it one more time after a factory reset. Went through the setup menus. No Sim card, WiFi through my old Xperia z, turned on my location. Opened the unlock app and applied for permanent unlock and BOOM.... Unlocked.
Don't know if any of what I did made a difference but try it if you want.
Best of luck to you all.

sim unlock possible? UK Vodafone

Sooo,
I bought a used vodafone moto g 1st gen naively expecting to have an easy sim-unlock available in the forums - maybe I haven't found it yet?
The online unlock code vendors I tried have refunded me saying they can't do my IMEI so I'm a bit stuck.
I flashed cyanogen hoping a new kernel would do the magic but I guess the simlock is in a different partition?
I see that a couple years ago http://forum.xda-developers.com/showthread.php?t=2903823 some were considering how the sim unlock modified the utag partitions. Does anyone know of further progress, information or solutions to sim unlock a moto g?
Or has anyone found a vendor that has successfully provided a UK vodafone sim unlock code?
P.S. Will I need to revert to the stock rom and kernel to use a sim unlock code?

The official Vodafone UK unlock service should work: https://www.vodafone.co.uk/vodafone-uk/forms/unlock-code-request/

Thanks Professor Gibbins.
Unfortunately the Vodafone unlock process asks for the vodafone number that has been used with the phone. Perhaps it would work if I got a pay-as-you go SIM from them and then provided that number.
Fortunately I tried paying a third unlock code vendor - sim-unlock*.net - waited a couple days and they came through with a valid code. I had started with the cheapest ebay vendors, so maybe they just weren't legit?
In any case, if someone else is in similar circumstances, here's what I learned:
There doesn't seem to be any other solution for sim unlocking the moto G xt1032 than purchasing an unlock code from an online vendor or, in the case of you being the original owner, from the network you purchased the phone from
Having a couple online vendors say they cannot get you the code does not mean another cannot
Neither unlocking the bootloader, installing a different recovery (TWRP), nor flashing a Cyanogen ROM will help Sim unlock the phone
The code provided by the online vendor did not work when I had Cyanogen installed. Fortunately I had created a backup of the vodafone ROM (using TWRP) and restoring their android version/kernel allowed the code purchased online to sim unlock the phone
Finally, the SIM unlock done in the vodafone system was maintained after restoring my Cyanogen install. I hope this means the sim/network lock will not return. It might perhaps resurface if I did a system restore; hopefully then the same unlock code would work again?

Once the unlock is done via an UNLOCK CODE, or via hardware unlocking tools, then it is permanent, so you shouldn't need to worry about this at all, but that said, in case you experience SIM un-/lock issues, then reuse the code when trying to unlock the phone on an OEM-DISTRIBUTED ROM (stock ROM).

Network Unlock Code Problem

Hello!
I have this problem - I had unlocked my o2 Galaxy S6 back in March when I was in Poland (code from o2), and used Plus Pre-Pay Sim when I was there. Everything was good and cool. Now, I am trying to put in a Virgin SIM into my phone here in the UK but the phone comes up with Network Unlock Code. So I first tried to use my code from March, didn't work. I have contacted o2 and received the same code again and it didn't work. I have tried different methods to no avail
What the hell is going on here?
Please help
Regards

Probably unlock code is wrong or you need unfreeze code

Unfreeze code ?
I can't imagine the code being wrong as its straight from O2 :/
