[Q] permanent unlock trouble shoot i am getting weird errors - AT&T Samsung Galaxy Note II

Okay so me, my friend, and brother all have bell note 2 and unlocked no problem with the hidden menu.
My friend recently got a note 2 off craigslist but it was 4.1.2 so i downgraded it to 4.1.1 since some menu option where missing. all the menu options were there and i assumed it unlocked. So i went and flashed clean rom, and inserted his sim card and its not unlocked and saying only emergency phone calls. i reflashed it to stock 4.1.1 and attempted again and again. and searched forums for a similar problem but i havent been able to come across any. So far it seems like it works but then i put a foreign sim card in and now it says unregistered sim. but in my note 2 its fine.
I put the sim card from the company the note 2 is from (bell) and it works.
Please help it would be so great ive been trying different methods and theories of my own for almost a day hours LOL. anyhelp would be appriciated thanks in advance.

upgraded to ICS now have sim card problem

Hi All:
I've upgrade to ICS using the Samsung KIES software. Now my phone is saying my sim is not registered on my network. and I keep getting an unlock screen whenever I reboot the phone. Also in my notice bar at the top it says : "Invalid sim card. Network locked sim card inserted." This sim card worked find with gingerbread before the upgrade but now is not working,
Any ideas what I can do?
thanks,
Amsu
it relock, sometimes happen when upgrade
Try the "galaxy sim unlock" app from google market to unlock. One of the members have confirmed it working http://forum.xda-developers.com/showpost.php?p=36613342&postcount=4 . At 2 euro's i think it's the cheapest unlock available.
Not sure though the method used by the apk to unlock. If want to be safe then buy the unlock code from ebay.
BTW this post belongs to general section and not development.
Thanks for the info. I ended up buying an unlock code. Now it works. Sorry about the post in the wrong section of the forum.
How come there's no 'keygen' yet to unlock for free..?
Moved to General and out of Development

[Problem] No signal/sim card inserted error after unlock!

Hey guys, i have a complicated issue with my newly brought Galaxy Nexus SC-04D, here we go:
1. I got it on 4.0.1, so upgraded to 4.0.4 and rooted and installed ****docomo v3.1.
2. It said phone is locked, selected unlock, phone rebooted twice then FC.
3. Reinstalled and opened it, showed phone is unlocked, congratulations.
4. Put in my sim card, phone shows no sim card inserted.
5. IMEI is the correct one, not generic.
6. When i put my Sim card before unlocking it never asked me to put in a code to unlock it.
7. Tried to restore it to 4.0.4 using Odin still no hope.
8. Tried the theory of unlocking it, still no hope.
9. Sim card slot is functioning because when i search for networks, it finds them.
10. ****docomo still shows phone is unlocked, tried locking and unlocking, still no hope.
I know the issue is not familiar, searched for hours but couldn't find any answer...
Any ideas how to get it to work would be very appreciated
Update: Doubted if the IMEI is blocked, but it's not, if this might help..

Noticed this strange network activity!! http://www.youtube.com/watch?v=DnHsB8ya-H4
What were the terms of you buying it? Used? I.e. why was the seller parting with it? Did you read through both the fdocomo.apk thread and permunlock thread? You're best help would be there. I know I looked at them at one time, and the permunlock thread was referencing an earlier version of fdocomo..
It was used yes, and i looked at Fdocomo & permunlock thread of course but still can't get any signal, not even for once!!

[Q] WiFi won't turn on

Hi all,
I have an unlocked Rogers Note 2. Recently came back from Vegas and I picked up a Ready Sim sim card to use for the weekend. Come back to Canada, insert my Rogers sim and now my wifi won't turn on anymore.
While I was in the US, I had used Will03 SlimKat ROM. I just recently downloaded this ROM to see if the problem would go away.
http://forum.xda-developers.com/galaxy-note-2-att/development/stock-rom-sgh-i317m-t2788546
The problem still exists. Is it possible the Ready Sim APN is still hidden somewhere on the phone and it's messing with my phone? This is a first for me. I'm stumped as to what the problem is.
Any help is greatly appreciated.

[Q]Help SIM unlocking Tmobile SGH-T999 for use in South America!

Hi all, I've been reading tons of threads and I am still having some difficulties with this phone. I am not in the US, I got this phone from a coworker that was going to throw it away and brought it with me to south america to give it to my friends mom who has no money, its and old phone but the one she has is even crappier ,I thought I would be able to just pop the SIM and get it going but nope.
If anyone could point me in the right direction I would really appreciate it, I have a few more days before I go back home and I would love to be able to leave this working for her.
Let me put you up to speed:
-Phone is running Android 4.3
-Phone was rooted using Odin, has SU and CWM
-Followed thread here to SIm unlock: https://forum.xda-developers.com/showthread.php?t=2023709 but #4 option is not present on 4.3
-I tried downgrading to 4.1.2 custom root666 to see if I could get #4 but to no avail since you cannot from this 4.3 version
-About to follow this thread :https://forum.xda-developers.com/showpost.php?p=48012926&postcount=8
but not sure if correct for what I want to do.
No more ideas, please help!
The phone can only be unlocked used an unlock code. Try contacting T-Mobile for a free unlock code or buy a code from eBay.
i'm with the same problem. i bought an sgh-i747 and after two months it bricked, so i replace the logical card (i don't remember how to say it in English, lol.) and boom!!! now i have a t999 and it doesn't work with movistar. (i'm from Venezuela)
but well, i've been reading posts about unlocking the phone and every one of them only works in JB 4.1.x. i don't know if i could unlock it by the downgrade process and i'm scared of getting the phone bricked again.
