Question [Q] Unlock code not working

I have entered the unlock code I received from AT&T and it tells me the request was unsuccesful. Any ideas as to why this might happen?

Well you could start with any kind of information about what ROM you're running

I downgraded to 2.3.4 and manged to unlock it via root and program. Is there a way to update to 4.0.4 again without losing sim unlock?

Why not just goes with the JellyBean? You are alreaedy rooted.
Current Phone: Galaxy S II [i777] > ROM: SHOstock3 Latest Released!!! [Got My Jelly Bean as of 1/29/2013]
Retired Phone: G1 Black 32B (unlocked) on AT&T | (Bricked as of 11/1/2011 [Due to my $tuP!t!d!ty for not using fastboot WARNING])

I was also slightly reluctant to go the app route to unlock the sim on mine, especially since the "legit" way seemed to be trouble free. On 4.0.4, I used #7465625*638*# to bring up the sim unlock prompt, worked without a hitch.

The AT&T rep also noted to me that you get 5 attempts before its permanently locked? any truth to that?

I originally posted this in the AOKP thread, since that's what I am currently running. I'll just paste what I had there for now.

Well, I'll be out of the country for a month or so, and I called AT&T to get the unlock code, which they gave to me after a few minutes of discussion as to why I needed it. However, putting it in yielded no results. I asked earlier (maybe in a different thread) if running an aftermarket ROM would have any effect, and I was told it would not. Was I told something wrong?
After doing some research, it seems that AOSP based ROMs seem to have issues with unlock codes. I'd rather not downgrade all the way back to stock, so if anyone has any suggestions or thoughts, I'd appreciate it.

Which rom did you use to upgrade to JellyBean? I have seen a few of them but don't know which one to use, plus will I be able to unlock the phone?

Shostock3. The current version is v2.5.1. Don't know about unlock. I am already unlocked officially by the vendor.

Yeah I finally managed to unlock it. I entered the MCC/MNC number for the SIM I am using and it worked. But you need the unlock code to add them. I will post the steps later.

[Edit]
Here are the steps I followed:

1. Turn the phone Wi-Fi OFF and then turn device ON without SIM card.
2. Type *7465625*638*#
3. You will see the NETWORK LOCK screen
4. In MCC/MNC field, enter MCC/MNC code for the provider you want to use. (example: enter 310260 if you want to use this phone for T-mobile USA Sim Card; 310410 or 310380 for AT&T). Check this link for complete MCCMNC for your provider: http://en.wikipedia.org/wiki/Mobile_Network_Code (It is very important to try all the MCC/MNC code if your New Sim Card Network has more than one code)
5. In CONTROL KEY field, enter the Unlock Code
6. Press OK
7. You should get a message: LOCK SUCCESSFUL
8. Turn off your phone, insert your New Network Sim Card and power ON. The phone should be unlocked.
