CustomROM in a unlock SIM Captivate

Hello,
I bought a Captivate in USA, the cell works fine in my country (Chile). I want to install a customrom, but I don't know if it's possible considerating the problem of the Sim.
I appreciated if you help me
Thanks

Hi, i bought a factory unlocked captivate from USA and never had a problem with custom roms. The sim never got relocked and i had flash over 20 roms on my phone. And i live in Argentina, without any access to an AT&T sim.
Though i would suggest, that you try to get your unlock code written down somewhere before you do custom roms, specially if you did not buy it factory unlocked. There is an app that gets the unlock code for you, I can't recall its name. Some of the phones get relocked after going back to stock; though I'm not sure if it is because they where manually unlocked instead of factory unlocked. What I do know is that when i tried to get my unlock code it wasn't anywhere, so I started flashing the phone hoping it didn't get sim locked.
If you don't get the code, flash and get sim locked there are several posts that explain how to unlock your phone. Those and the "universal sim unlock" gave me some peace of mind at the time.

Thanks!

Back up your efs directory. It is possible to relock and be stuck if you don't. There is no factory unlock captivate. All are att and have to be unlocked via code.

[Q] Unlocking HTC inspire from AT&T no unlock prompt?

Hi everyone. I received the unlock code from AT&T and after I insert my non AT&T sim card and boot the phone up, I don't get the network unlock prompt. I get "sim not provisioned mm #2" how do I get the unlock prompt to come back up? I was rooted and running CM 7, but flashed it back to a the non rooted HTC stock rom from HTC's website. Any help/ideas are appreciated!

Are you SIM unlocked or bootloader unlocked? How did you root?

I'm sorry, I don't understand the difference between SIM unlocked & bootloader unlocked, I just want it unlocked so it can be used on different carriers. AT&T has already given me the code to use.
When I rooted, I used aahk, but when I put the stock HTC rom back, I lost root access.

Are you still S-Off? Which carrier's SIM are you trying to use? Some carriers lock their SIM cards, so only SIM unlocking the phone doesn't work.

Yes, s-off and I tried a verizon and a tracphone SIM
also tried a red pocket SIM and t-mobile SIM. I get the "sim not provisioned MM #2" message. No prompt

Since you used the aahk and are still soff than you already have Sim unlock. Not all carriers and Sims play nice with unlocked phones. Sometimes a different Sim will do the trick.
Example when I had unlocked my iPhone way back in the day (original) it would not work using my sisters tmo Sim but it would on my brothers tmo sim

Sim not provisioned mm#2 usually means the Sim card hasn't been activated, if the phone was Sim locked you would be prompted for the unlock code. Sounds like you're ready to go

Xperia Z3 D6616 SIM unlock or Custom firmware

hi
i am having my Xperia Z3 D6616 idle for more than 5 months, meaning? its not sim unlocked. actually unable to unlock it. i did not know that t-mob disabled the SIM unlock code pop up in their phones.
i am not in US right now so unable to unlock the phone as i bought from ebay as new. totally fed up with this situation.
i am tried all over the forum and waited log time to get the root, i felt it will be unlocked after then. but unfortunately rooting did not shed any light on unlocking possibility.
so far
1. D6616 cannot be Sim unlocked without Tmob support
2. No custom firmwares.
3. will not boot if international Firmware flashed via flashtool. or flashing pre rooted zips.
4. its known that it the boot loader cannot be unlocked.
i am looking for D6603 firmware ported to D6616 so that we can flash into recovery and get the sim unlock code Pop up to Enter the unlock code.
or anyway how to port the simunlock app from international D6603 FW to make it work on D6616.
I saw and tried HTC one M9 T mob sim unlocking method and it worked on HTC one M9. (the link is below) is it possible can we follow the same method to unlock the D6616 also.
looks like T-Mob disable sim unlock pop up in their phone to restrict the user to unlock as they wish.
link : http://forum.xda-developers.com/one-m9/general/sim-unlock-method-t3143333
i request some developer help how to get this done. i believe they are so generous and helpful. at least some guides on how to make it.

I'm facing the same problem, all servers are down indefinitely. One guy also found if your phone never were used or registered in T-mobile network, can't be registered as elegible to unlock, this is my worst problem, I'm outside of USA with brand new expensive phone . If some one found any other solution to unlock, I'll appreciate the information

Unlock service is up.
Now we can unlock xperia Z3 with t mobile app,
The service is up. I bought the unlock service from cellphoneunlock.net
This service cost 50$, but this is the only option for D6616. Time will 3-6 days. I unlocked two of my D6616 after years

not that I believe in pay for those type of services. but I have a z3v and am in a similar position. I was wondering if you could check if your bootloader unlockable status has changed from no to yes or how can u flash stock z3 firmware with only a sim unlock.

This has nothing to do with the bootloader, it is for unlocking the sim only. The z3v is alread SIM unlocked, but, like the T-Mobile d6616, the bootloader is locked and likely to stay that way.

[Q] Purchased Online (Unlock Failed):

I purchased a Galaxy S7 online, came with a T-Mobile receipt showing the device is paid in full, upon my request the original owner used the unlock app to request a permanent unlock before shipping and it was successfully unlocked. I received the device about 3 days ago everything works as it should, I opened the unlock app just to double check and requested a permanent unlock again and got this message (Unlock Failed: This mobile wireless device is not eligible for unlock etc...) I know the device is unlocked I tried an inactive AT&T sim and did not request a code. Anyone can tell me why the unlock app does not recognize that the device is unlocked, thanks in advance.

You might have to call t-mobile or log in to your t-mobile account and see the unlock status or your device..how do u know the original owner was able to successfully unlock the phone? It's it works with another carrier sim then the phone sld be unlocked and it sldnt be an issue..maybe it's giving up the error msg since it's already unlocked

99% certain that if the device is unlocked, the device is simply unlocked and that's that. If the SIM works you're good to go and any further attempts fail.

Finally T-Mobile website updated the status of the device as unlocked and can be used with any GSM network, but the unlock app still fails to show that, every time I try I get the same message (Unlock Failed) anyone out there has a fix for this error?

Not sure I understand your question.... the phone is already unlocked so the unlock app will give u an error message....cause it's already unlocked...Good luck man...
Sent from my SM-G930F using XDA-Developers mobile app

I have my Samsung Galaxy S7 Unlocked by app. If I try the unlock app process again I'll get the (unlock failed) that means nothing. Put a active simple of another GM Carrier, if it works you are all set. It won't ask to give any code, it will just recognize the other Carrier. Hope this helps.

Have you had the phone activated with an active SIM inside of it for 40+ days?

Yes, that's what T-Mobile states you need to fulfill in order unlock your device.

If you're not the original owner, they WILL NOT unlock it.

you need to be on t-mobile firmware

Flash back to the T-Mobile firmware with MSM Download Tool, then unlock with the app. Then flash to the international firmware again with MSM Download tool then you'll be able to fastboot oem unlock without issues.
