unlock Samsung Captivate

How i can unlock Samsung Captivate? so i can use on T-mobile its new phone. is there any risk?

Yes, you can. There are plenty of posts on how to do it here.
The only 'risk' is that you won't get T-mobile's 3G, only Edge, as the Capitvate doesn't include T-mobiles 3G bands.

UCJI6 captivate upgrade

So i've bought a used captivate off ebay which came with ucji6 froyo on it. i've been reading wikis and threads for a week now, i just managed to get it rooted via adb.
i've seen people saying their devices got re-sim locked after flashing. i did not have this phone when it was 2.1, so i don't have the sim unlock code. I need to know what I can safely flash without resetting the simlock.
pointing me in the right direction would be really really helpful.
thanksguys.

The program on this thread, odin, allows you to flash bank to 2.1. You can but flash anything from ji6 directly. Learn how to use odin, flash stock, then choose any rom available.

but will it retain sim unlock.

On stock you should be able to get the sim unlock code, thus flashing other roms you should be able to reuse it to unlock

[Q] Unlocking Bell I9000M With Froyo JL2 on it

I'm leaving for Europe in a week and would like to take my phone with me and use a pay-as-you-go sim card when I get there.
Anyone try unlocking this phone with the most recent JL2 on it? If so, would you mind giving me a complete step by step on how to do it?
I've read the Unlock thread, but there are so many methods and tweaks people have done, its all confusing. Either I'm not reading it correctly or I'm just not understanding it. I've seen change numbers to this or that to get it to work with Rogers, but is that a complete unlock?
Please provide me with a step by step.
P.s. my phone is completely stock, no root or anything if that helps.
Any help would be greatly appreciated.
Thanks!

Well,
As you can see I'm very weary about doing anything to this phone, seeing as I just got it replaced after a drawn out discussion/argument with Bell.
If no one can tell me the exact procedure on JL2, then I'm going to leave it well enough alone. I'm sure someone will come out with a perfect Unlock apk in the future just as they did with JH2. But for now, I'll sit and wait unless someone knows.
Afterall, Bell wants $75.00 to unlock it. I could go to Europe and probably pay less than that for a Pay-As-You Go model.
Keep up the good work developers.

I'm pretty sure there's no way (easy or lock) to unlock any Froyo builds right now, sorry.

That Unlocking software does not work on 2.2+ ?
I thought it was simply extracting some info off the phone?
If not you can always make a backup , flash to JH2.
Follow that unlocking guide, which does a SIM Unlock.
So it's unlocked forever.

Just a question about unlocking, does it void the bell warranty? Maybe I should just extract the code now and I can use it later once my warrenty is up? once i extract the code i should be able to use it no matter what firmware i'm on in the future right?

Ok, so from what I'm reading on here it can't be done with JL2.
Now my question is, can I load JH2 on this thing, grab the unlock codes, then use the same lock codes after JL2 is reinstalled?
Furthermore, are these unlock codes only good for going to Rogers or will the phone work in Europe with the same unlock code?

I was on 2.1 when I unlock my bell..
I upgraded to jk4 2.2
Is still unlock...
Seems like updating firmware doesnt lock the phone

At&t - Wanna unlock for all carriers

Root and carrier unlock are different things. Carrier unlock requires a code from your provider.

Would he need to do a carrier unlock even in the case he installs a new ROM on to it? (even the ODIN One-Click stock ROM?)
Sorry, just curious myself!

What he describes is the fact that in 2.1 ROM, carrier unlock code is very easy to extract from the phone (it is not encrypted). But once you flash to any 2.2 ROMs, the unlock code is now encrypted and much difficult to extract but still doable.
Flash back to 2.1 will not give you back the encrypted unlock code. So, it is important that get get the unlock code while still in 2.1 and write it down somewhere.
There are instuctions posted in dev forum about how to extract the encrypted unlock code in 2.2.
Regardless which ROM you are on, your unlock code stays the same unless you flash to a custom ROM that is not properly ported to Captivate and it will likely destroy your IMEI, product code and unlock code.

Ah I see! So much like the CM7 ROM then
So I'm guessing my phone was already unlocked somehow beforehand...

Call ATT, make up some BS about going to Europe on a trip. Tell them you already bought a prepaid sim card for an international carrier and you need the sim unlock code for your phone.

Custom ROM has nothing to do with unlock status.

Exactly, that's what I'm meaning
I've never unlocked my phone, yet it's unlocked.

How do you know it's unlocked? Are you using it on a different carrier than when you first purchased it? Are you using prepaid SIMs in it? That's what carrier unlocking allows. Rooting allows access to the base OS so you can run certain apps and make mods that involve the system. You can be rooted and locked or unlocked and you can be locked or unlocked and not rooted. One has nothing to do with the other.

I never said they had anything to do with each other, I'm much aware of how they both work. I'm both rooted and unlocked (not bound to any carrier, and yes I use prepaid SIMs).

[Q] Questions about unlocking and rooting after Samsung 2.2 update

OK first post here. I have done a fair bit of reading and searching but still have a couple of questions. I have just bought a Captivate. Made 3 phone calls with it and that's it. It has already been rooted and unlocked by the seller. I know if I upgrade to 2.2 via KiesMini it will remove the unlock and root. After the update can I unlock and root again. ? I hear Super One Click might root it. I have the code numbers from the original unlocking. What can I use to unlock it? Thanks

you dont lose the unlock by updating it. even if you did, you have the code so it doesnt matter. you dont need it unlocked if you are staying on ATT....unlocking is so you can stick another providers SIM card in and use it on any GSM carrier

I am not on AT&T. I have an AT&T phone that's used on Roger's. That's why it needs to stay unlocked.

if you have the code then it doesnt matter if the unlock goes away.

Use the SIM you intend to use plus the code previously extracted. [APP]SuperOneClick v1.7 (Root, Unroot, Enable Non-Market App works on Froyo.

Update. Unlocked and rooted phone. Updated with Kies Mini to Froyo 2.2. Phone remained unlocked after update. Root was gone. Used SuperOneClick 1.7 and root was back. No problems at all.
