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.

Hello All;
I am using my AT&T Captivate on Canadian Rogers network with a seller supplied unlock code, as well as a "sgs unlock.txt" file in my phone.
If I ever do either OTA upgrade to Froyo, custom leak upgrade to Froyo, or any kind of flashing such as stock ODIN and such, will the unlock code ever change or can I be using the same unlock code, if the phone ever decides to lock itself again?
Cheers!

Hmmm....good question. I thought i read somewhere in these threads that when you flash ANYTHING (beyond eclair/ jf6 build), that you do lose the unlock code. I could be wrong. These are one of those times that i wouldn't mind being wrong. lol
Hi,
Does anyone know how to re-lock the SIM on Captivate? I need to reload the stock ROM and lock the SIM for warranty replacement of my phone.
Thanks in advance.
I believe once you reload the stock ROM, say using Odin one-click to JF6, your phone will be SIM locked again.
Again, I believe this is the reason why they recommend you write down your unlock code, because you'll have to go through the unlock process with every flash.
Thanks for your input but unfortunately once it's unlocked it will stay unlocked. I tried it many times myself flashing the 1-click Odin stock ROM.
I wrote down the unlock code. I actually just found this on a website but I am not sure if this will work. Wondering if anyone ever tried it...
*#7465625# = Check the phone lock status
*7465625*638*Code# = Enables Network lock
*7465625*746*Code# = Enables SIM lock
If I remember correctly, I believe I need to enable the Network lock....

Not true. I have flashed many ROMs and stayed unlocked. Am currently running Perception 4 without having to re-unlock.

After you get the NCK code using the method above, enter: *7465625*638*#
There will be a pop-up box.
Complete the first field (MCC/MNC) with the network you want your phone locked to (eg. 226 10 where 226 = romania; 10 = orange etc.) and the second field (Control Key) with the NCK extracted from the .bak file.
Press OK and your phone should relock.

NCK codes are different for each country/carrier. You will have to search for yours.

Thanks. I have the NCK code for my phone. Searched wiki and found this link.
http://en.wikipedia.org/wiki/Mobile_Network_Code#U
It seems like AT&T's MCC/MNC is 310/410.
I will have to give it a try tonight.
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?
Sent from my GT-I9000M using XDA App
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

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).

i have a Sony Xperia Z1. the model number is C6906. i bought it directly from Sony and its Unlocked . it was working on every sim card. But i flashed the C6906 firmware of the other branded network provider. now it's network locked with that network provider. it only works with the sim card of that network. when i put any other sim card, the dialog box appears and it tells to insert network unlock code. when i contact that network, they told me to get their sim card and use it for 90 days. then they will provide me the unlock code. why should i have to use their sim card for 90 days to get the unlock code, because my phone is already factory unlocked from sony. i went to 3rd party websites which provide network unlock codes. but they didn't find the unlock code for my phone, because that phone is not present in the database of that network provider. that means i can only get the unlock code from that network code by using their sim card for 90 days. but that network is not working in my area. please suggest how can i make it unlock again as it was before ? i will be very thankful
flashing FTF files will not affect the SIM lock status of a phone.
It will neither lock an unlocked one nor will it unlock a locked one.

i flashed the firmware of Rogers for my unlocked xperia z1 C6906, which was Branded Firmware. my phone was working fine with all sim cards. but few days ago i put the sim card of rogers, the phone automatically restart and also install some rogers network apps in phone menu. after that when i put other sim card, the network unlock code dialogue box appears. it means that phone got locked with rogers now. the rogers technicians said me if you flashed rogers branded firmware, then if you ever put rogers sim card in it, then device will locked to rogers even if its unlocked from sony.
well, not sure how that works as its the first time I ever heard that happening. Not that I don't trust operators but I often find they do not know what they are talking about when it comes to the kind of things we do here at XDA
But, if what you say is true, flashing another FTF will NOT help.

can xda developers develop any software for that ? so that the network unlock code dialog box disappear and phone reset with original factory unlock setting

that is not really what we do here. there are loads of websites for that, and rogers say they will give you an unlock code in 90 days anyway.
