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] Sony Xperia U network unlock

It's probably a n00b question so apologies in advance, but if I root / bootloader unlock and Cyanogenmod flash an Android phone that's locked to a certain network, will that network lock be removed along with the official default Android ROM? Or is the lock at something like a BIOS level (or whatever the smartphone equivalent of a BIOS is)?
I bought a pre-unlocked Xperia U about a year ago that I've been using on Vodafone and had to return it under warranty (got stuck in a boot loop despite the fact that it's totally unmodified, not even rooted, honest!) and the replacement they sent back is locked to Virgin Mobile. They're telling me that the phone I sent them was originally sold to Virgin in France and locked to Virgin before I bought it, and that they've therefore fulfilled their responsibility. So I'm just wondering now about unlocking, and I've always been curious anyway about how / if bootloader unlocking, custom ROMs etc are related to network unlocking.
Thanks in advance for any help you can provide with this!

well u can unlock it.. by getting the code from sony..
It will also unlock the ph..'s Sim lock..
Or ask the sony officialy for this.. they'll provide u every info required.
But unlocking the bl will do the job for you to be sim free
But do double check this from google too.
Also before unlocking pls make a backup as it will wipe everything from the device.
Just unlock and don't flash any custom kernels.If you want to then do it carefully pls with a backup and a copy of flashable stock rom.
Flash custom roms based on stock kernels
Hope this will answer the query..

Thanks for your reply! I spoke to Sony and they just told me to contact the network (which have done and they're wanting to charge me a fee to provide the unlock code). So to clarify, if I root the phone and unlock the bootloader, the network SIM lock will also be removed?

Not by rooting but also i guess not even by unlocking bl..
how much are they charging exactly..
i'll try to find the link for this
Also check this that how many times is the code applied for unlocking..it should not be 0
use this *#*#7378243#*#* in dialer
then service info sim lock

When I dial that number, the number just disappears. What is it for? They want £15.32 for the code. Should I just pay them and forget about trying to remove the lock?

Sorry the code is this
*#*#7378423#*#*
check the sim lock counters should be zero in all..
if zero then once u can try googling the code for unlocking if they work then it's great.
if not then it would be better to pay them for this as its a bit risky..
and are u using virgin's network??
As it's cheaper what they areaskingfor i guess.

[Q] SIM Unlock/Flash factory ROM/Root

Hi all,
Not got the G yet but looking to get one for my sister from Tescos as soon as I can. I see root is now resolved via "superroot", I see that people are getting SIM unlock codes from eBay etc. All good.
I see a lot of talk about flashing the factory rom over the Tesco one - but see many ifs/buts/maybes. Has this 100% been done by anyone?
Finally - if bootloader is unlocked, factory rom installed do I actually need to get a SIM unlock code too? (I would have hoped that would be enough but looking for confirmation from those that know!)
Cheers
Chris

If you want to use a different network other than tesco you will need to obtain an unlock code, unlocking the bootloader and flashing roms will not unlock the device to use other networks

Cheers for the info. Fair do's I guess....

[Q] Will I lose unlock if I install a new ROM?

Hello, my name is Armando. This is my first post here, and I only have one question. First of all I want to say thanks to all you guys, I've found a lot of useful stuff here for my phone Ok, let's go for it:
I recently unlocked my Huawei Y511 to use it on any carrier, and it was succesful (I didn't unlock it by myself, a repairman did it). The problem is... my phone still got all the original carrier stuff (boot animation, some crappy apps and sounds) and I want to delete all of them. I rooted my phone before the unlock (temporary root which I found in this same forum: http://forum.xda-developers.com/showthread.php?t=2130276) and I leave all the stock ROM untouched before the unlock. I noticed that the guy who unlocked it used a "unlock box" named "SigmaBox" and he told me that my phone was able to be unlocked directly, without needing to wipe and reinstall all the software (I give him the phone, then one hour later I have my phone all unlocked, and it was the same way it was before it).
Now my question is... if I install a new ROM or whatever... will I lose my sim unlock?
I don't understand how he unlocked the phone, all I know is that he did a "direct unlock" but I don't know if he used unlocking codes. All I know is that he used some kind of USB box connected from my phone to a computer, and did his magic and surprise, phone unlocked.
Do you know what kind of unlock is this? And how does it work?
PD: Sorry for my bad english, my native language is spanish but I'm trying to improve my english skills (so I didn't use a translator).

I don't know much about unlocking. But I'm pretty sure that you won't loose the unlock status if you flash custom rom

Thanks for your reply, and yeah, I think you are right.
After doing a little research, I found that a "direct unlock" is basically the generation and input of unlocking codes generated by both IMEI and carrier code, and the unlock box generated three codes which only one of them worked and the phone gets unlocked. So, my phone is
unlocked for ever and I won't lose my unlock status even if I install/update/reinstall the ROM.
If any of you guys know something else about this unlock procedure, please let us know!

Boot loader and other questions.

I have a Verizon droid ultra. I couldn't find it on the unlock bootloaders link posted in the beginners Guide. Is it possible to unlock the bootloader?The phone isn't a developers phone. I have one last question, if I remove the sim card can I flash T-Mobile framework and use family mobile?

The non-developer edition is not normally supposed to have its bootloader unlocked. In order to unlock it, you must get an unlock code from Motorola, and Verizon has instructed Motorola not to give out codes for non-dev devices.
However, if you act fast (because who knows how long this will actually be an option) you can buy an unlock code for $40. This basically involves sending your IMEI to someone in China who sends you back a code, which seems a little sketchy. However, the codes coming back are valid and do in fact work, so if you're willing to look the other way on how the codes may have been obtained (for all we know, that database "fell off the back of a truck" so to speak), then go for it.
