UCJI6 captivate upgrade - Captivate Q&A, Help & Troubleshooting

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

Is it safe to flash simlocked Galaxy S?

Is it safe to flash simlocked i9000 with odin?
IMO theres no connections between flashing and simlock, but want to be sure.
Cheers.
I flashed my simlocked SGS using Odin and I had no problems. There are other few cases in the same situation and they had no problems.
Will a new ROM get rid of the simlock?
no, it wont, this would be to easy to dream of...

No problem to flash, I did it many times already, try also 2.1 and 2.2 android on it, lag fix, etc. Everything working normally...and, of course, the lock remain in place!

Mine is simlocked. Flashed sever times and all is perfectly !
just make sure to run Odin on a windows machine with English US settings

My phone has simlock.
But i dont now of i can flash it to JM5?
Somebody now how i can unlock my phone ?
My precious is simlocked and I had no problems flashing other firmware. For example now I'm running a pre-rooted XXJP3 flashed through Odin. You cannot get rid of the simlock by flashing other firmware, you have to buy the unlock code. I'm waiting mine.

I tried with globalunlock but they were not serious, I had to raise a dispute/claim to Paypal to get my money back. Now I'm trying with someone from my country (i know his name and address in case of.... )
Hi!
My Galaxy S was locked too.
I tried unlocksamsung.co.uk and they sent me back an unlock code in one day. Everything is fine now.

[Q] Unlock code and flashing

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

[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

[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.

Ismy phone still unlocked after flashing ICS rom??

I unlocked my phone while it was on 2.2 using glaxy s unlock app from market.The other day i flashed ICSSGS RC4.1 rom and it changed my IMEI. Is my phone still unlocked?? I checked the rom's zip file and it doesnt contain efs folder which should mean that it didnt overwrite efs folder that contains unlock data. So my phone shouldnt be relocked right (i hope not because i need to use it in Europe in couple weeks ) ???
I'm interested in the answer to this as well. I unlocked mine whilst in gingerbread....but now that i have upgraded to ICS....is my phone still unlocked? I don't think my IMEI changed though....
I unlocked mine in froyo and its still unlocked..I am on ICS now....
i flashed ics and had to "re unlockb

Typically, once unlocked, always unlocked.

Interesting. I unlocked mine in GB and updated to ICS over the weekend. Wanting to order up a straight talk sim and try it. I did verify that my IMEI matches what it is supposed to be. Hopefully it remains unlocked. I guess worse case is I have to drop back to 2.3.
Have yet to find a *# combo that will show you the lock status in ICS.
Did it change your IMEI back to 04999...whatever. If so, flash again because that is the default IMEI, mine did that before and I just reflashed from a stock oneclick. I think it somehow doesn't read the IMEI correctly sometimes. You might try one clicking back to GB(without bootloaders if you've already got them) and then diagnose from there.
Whenever I flash back to stock using odin, it relocks. But I have my code handy.
I ordered and installed a Straight Talk 'AT&T' sim this week. Everything is working as it should. I did check the hex code and the unlock bit was set, however, I have heard that the ST sim cards are unlocked so you don't necessarily need an unlocked phone. It doesn't really verify that I'm still unlocked, but I thought I would mention that in my case, I had no problems.
