I'm using CM7 and recently network unlocked my phone as I am going to Europe in a few weeks. I know on stock roms you can use *#7465625# and it will bring you to the network status screen, but this doesn't work on CM7.
Does anyone know how I can get to this screen?
Thanks for the help guys.
I did some more research and found out the number combos/system menus are specific only to captivate roms so I'll have to flash to stock/modified stock rom in order to check. NBD
However, I don't know whether the network unlock is persistent between roms. Do I have to unlock it everytime I flash? Everytime I change roms? Is it one-and-done?
Does ANYBODY have any knowledge on this subject?
SGS Unlock Pro makes a backup of the original and modifies a particular file. This file has bit settings that seem to control lock status.
I don't remember the exact file. I guess as long as the file doesn't change, you'll stay unlocked.
looking at my phone, I think the file is nv_data.bin

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .

However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

Hi All,
I got my samsung captivate rooted successfully. i got the so called unlock code from nv-data.bin file. when i gave the unlock code on my phone, it said the unlocked failed, but i was able to use radio of my new sim. I am able make calls and stuff, but i am not able to to use data network on my phone. I am not able to configure an APN setting in my phone. It doesnt get added when i click save button.
I am confused guys....please help me counter this issue.
TIA

Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!
I've still not been able to fix, but will update when I do in case it helps anyone else :good:
Hello Everyone,
I have scoured the internet but I can't find a direct answer. I am running a 5.1.1 AOSP rom and am traveling to Europe soon. I want to use my phone there and T-Mobile tells me with my plan that I should be able to use it because I am on their simple plan. I was given a instruction manual on how to set it up but the app it says to set it up with tells me that my device is not compatible.
My questions are:
-Am I able to use my phone while I am in Europe?
-Do I still need to sim unlock it?
-Do I need to flash back to a TW ROM to sim unlock it?
-Has anyone had experience with using a custom rom in another country?
Thanks in advance.
Im not sure this is gonna be much help bud but I used it on my note 3. Definitely worth checking out.

My questions are:
-Am I able to use my phone while I am in Europe?
I'm not sure if you're going to be able to text or call from Europe from an AOSP based ROM, I personally haven't tried it but I know there's a setting that allows for roaming. You could use wifi though, obviously. Not Wifi Calling or Wifi texting though (to my knowledge)
-Do I still need to sim unlock it?
I don't think so on an AOSP ROM, however if you try running an Int carrier on your N910T it won't work because of incompatibility.
-Do I need to flash back to a TW ROM to sim unlock it?
I'm not sure if there's a sim unlocker for the device that run int carriers.
-Has anyone had experience with using a custom rom in another country?
Not me
I don't see how rom can affect your service. When I went to Asia I was on a custom tw rom (yes I know it's not aosp) and was able to text, call, and had internet (128kbps or less). Don't remember trying WiFi calling though. But I didn't have to sim unlock.
With your rom are you able to use all your carrier feature? Except WiFi calling of course. If you are then I think you will be fine. If you want to be safe just back up your rom now and go back to a tw rom and set up your phone again. Make a back up of it then go back to aosp. When you get to Europe just switch roms if you have issue with aosp.

Hello everybody!
I flashed a lot of phones, however I am struggling with this Note 5 N920T a bit. Bought this mobo from Chinese reseller, looks like everything is working okay, however if I want to update the software, it reminds me that ROM was changed and I need it to flash it over cable. I am perfectly aware of ODIN, however the board is unlocked now for all the networks globally.
I tried to check the T-Mobile Device Unlock App, however tapping on a "Permanent unlock" option brings me message "Unlock failed" - try to reboot and try again.
So, questions!
1. I downloaded the Nougat original ROM for T-Mobile USA and generic ROM. Would you say that the device unlock will remain after flashing? I would try the T-Mobile firstly, if that will work, I´ll try the generic one. I assume it will be working again...but that sim unlock...will it last?
I wanted to do full backup, however the board is not rooted so I rather asked the reseller for sending me the ROM file that is actually in the phone (currently waiting for it)...and just roaming around about possibilities.
Thanks for any help in forward guys, you´re the best!
The unlock was probably done through third party software or a EFS method.
You can forget about the Device Unlock app from now on. It will remain unlocked as long as you don't rebuild the NV data.
That means that you can flash the T-Mobile firmware on it, or you can flash any other available custom ROM that can work on it.
The update error is probably appearing due to an unofficial system status.
Go to Settings>About device> Device status and make sure it says official.
If it says "Custom" then you have your answer. If it says "Official" already it's good to be flashed with the software of your choice. Is up to you!
