Sim Card Lock - Galaxy S 4 Q&A, Help & Troubleshooting

Hey, I rooted a T-Mobile S4, and used RegionLockAway to get rid of being lcoked with T-Mobile. Any simcards i place into the device, it asks for a simcard pin. When I place the sim card in my Nexus 5, there is no pin and works flawlessly. What can I do? I tried deleting the data of the device and its still there. Thank you

All data , music , pictures, settings. apps in your internal SD , back up first so you can restore after it
did you check your settings?

Yeah I went into settings, the only option is Lock SIM card, if I press it, it asks for the previous sim card pin, which I have never put on... Would reflashing the ROM work instead of having to factory reset?

Yes , but i would be the same , if i understood right you are stock , so you have to flash with odin , so you will full wipe the phone to do it.....
Why you do not use an app like titanium back up , back up all your app and data , contacts...do a full wipe and restore everything but system settings...
or back up you contacts , use pc to back up all movies , music ,pictures , documents you got factory reset copy everything back configure google play so all your app are restore....i like this better
or do as above but instead of factory reset flash with odin

The phone was locked to T-Mobile, but now I live in Australia.. can you not use Australian sim cards for a T-Mobile device or something? cheers.

Just be patient and give the guys here some time, remember that in some parts of the world is midnight right now. Now, I assume you have tried that same sim card in other phones to make sure the problem is not the sim card.

[Q] Please advice!

How is it possible that my friends daughter that is 12 managed to do a full factory reset of my phone with pin security in place?
Phone was locked she asked me for the pin I said no... She thought that she would be able to guess it. 10 minutes later I see my phone laying on the table. I picked it up and noticed full factory reset with sd card erased.
I asked her what she did and she said that phone just restarted after several wrong pin entries and that she left it on the table during the restart
PISSED AS FUAAAAACKK

Yeah pretty sure it's for security. If you enter wrong pin 10 times then everything is wiped
Sent from my GT-I9505 using XDA Premium HD app
"Yeah pretty sure it's for security. If you enter wrong pin 10 times then everything is wiped" Yeap I called tmobile S4 comes with this great security feature... I will try to run data recovery software on my sd card. Do you think I will be able to get my data back?

In this case the EXTERNAL SD card is not wiped so you can recover data with your computer.
Internal data may be also available , check them with explorer after restarting your google account.

that raise the question if this "feature" is only a nice "Tmobile great security tool" or apply to any Sammy Roms.
In this case the wipe, as you confirmed 100% done on all the 2 SDcards, is much better than the Google ADM that is just able to wipe the Google account related stuff and not any other data. ( I tested it with my phone in order to know!)

Samsung Note 3 doesn't want to recognize/register my SIM

I'm not a 100% sure how this problem occurred, I believe it was after flashing an S5 custom rom called: "RC Elite S5 Port V16" To my Samsung Galaxy Note 3 (N900W8). From what I was reading it was a ROM that "converts" your note 3 to a note 4 or s5, while still having all the Note 3 features. Another possible cause is trying to use RegionLock Away.apk by Chainfire to essentially(unlock) the phone. I feel like this is the main cause though as this affects the modem on the phone. This isn't the SIM as I tried it in another phone and works fine with calls and texts.
My phone doesn't want to register its mobile network anymore. When I try to make a call or text it says:
"Not Registered on network"
I was reading online for about 2-3days now for possible solutions that can cure this. Such as:
1. Going into Mobile Networks settings and manually register [failed, details below]
2. Going into Mobile Networks settings, hold home button for 2seconds and then hold power button + home button for 15seconds [failed, details below]
3. Taking out battery while the phone is on and remove the SIM card, clean it and re-insert [failed]
4. Factory Reset [Failed]
5. Wipe Storage and re-flash stock ROM [Failed]
Options 1 & 2 do not work because when I try to access Mobile Network Settings I get this:
"Insert SIM card to access network services"
The SIM card is inside the phone though...
So what I did is found a mobile network options shortcut "program" from GooglePlay Store and installed it. It allows me to access the menu, which is great! Now, when I try to register the SIM card to my correct service provider (BELL CANADA)...it will make me wait for about 1-2minutes before I get "Unable to register, try later" error.
I tried the factory restore with a stock 4.4.2 ROM from Sammobile and the issue is still there.
Is there anything that anyone knows that can help me resolve this problem? I tried EVERYTHING i can possibly find on Google. I've seen posts of people suggesting to flash a modem.bin file with Odin but I don't know where to get those files, nor what to look for in terms of modem file "types".

Many thanks for your swift replies. I have it layed out in an album with thumbnails at the top. Hopefully it made it easier for you to look. I skipped past DEVICE ID as a whole as both IMEI and SERIAL #'s are 100% original and legitimate.

I tried region unlocking it with RegionLock Away by Chainfire. I would like to say afterwards this issue occurred but as far as im concerned, using a TELUS Mobility sim card activates the network pin unlock. So i'll be going with no, it's not unlocked.
I currently have a Bell LTE 4G SIM card installed on the phone. If you check the photos there it shows I have a full connection but unable to make calls nor access the mobile networks menu.... =/
I can provide pictures on the error messages if you'd like.

Edit: I'm performing a factory reset right now. I'll let you know if this fixes it. Thanks.

And as mentioned in OP, I downloaded a shortcut from the GooglePlay store that allowed me to access the Mobile Networks options. When I try to register to bell i keep getting "Unable to connect, try later"

Do one thing.
1. Turn off the phone. Take a out the simcard and battery for some min.
2. Add the battery only. Turn on the phone and factory reset your device (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Insert SIMCARD without turn off the phone.

They there! I tried to follow all the steps to the best of my ability but it seemed that didn't work. For 1, the note 3's sim card slot is blocked by the battery so i can't take it out without turning it off. In addition, after only inserting the battery and performing the factory reset, I decided to test it and the issue is STILL there even though a sim card isn't even inserted AFTER the factory reset. Same error messages as if nothing ever happened, even shows full bar reception even though nothing is in there. =/
This is the most unique problem I have ever encountered myself. I really don't know what to say...

Bumping.
After some more research I was wondering if you reflash the stock firmware back, does it effect the EFS partition at all? Cause if it doesn't I believe I installed a faulty EFS partition accidentally which results in the broken connection.
Any way I can get a backup of an EFS file that I can flash?
Thanks.
Bump. This issue is driving me nuts.
Thank you in advance.

Thanks in advance for the replies.
I had this same problem earlier (for a note 2) in the week where it just wont register any sim card.
In my case i think the problem was that i did a full format before flashing which probably deleted the EFS folder.
I tried so many options and eventually managed to resolve it by following the following instructions to restore the stock firmware.
Edit: Unfortunately i cant post URLs as i dont have enough posts

Hey there!
Thanks for your swift reply! I had already did the Samsung Recovery via Kies 3. Do you know if I reflash it that way that the EFS folder would get flashed as well? Because after doing those steps the issue is still there, after about 3 firmware recovery flashes. xD
I didn't even think about backing up the stupid EFS folder otherwise I would have. I was looking at this

Is this the same one? xD
Thanks again.

Mobile data doesn't work after chanhing a ROM

Hi. I was originally on Pixel Xperience, but I decided to change to Candy. I read that mobile data is working there so I did it without any doubts about it. I factory's reseted my phone with TWRP deleting also system, because I wanted a fresh start... And everything went smoothly, but now the phone refuses to recognize any of my two sim cards... One of them is 4G and the other one isn't.
Does any of you know a way of restoring my mobile network service? Preferably without having to reflash stock or something.. thanks in advance for just reading this!
