Where I can get this app "Network"?
Some of those steps are placebo, and unnecessary. That will only get you 1x internet, and dependent on your location you may/may never get 3g to work they've been blocking off more cities from flashed phones from getting 3g..

[Q] Anyone have 0/12 IMEI number but network semi work and EFS missing NV_data.bin

I installed the jedi mind trick JB6 rom a week ago and everything worked great up until a few days ago. Now my phone when connected to wifi can't access the play store, gmail and other apps. I can receive/make calls through wifi calling and texts just not internet data. As soon as i turn wifi off everything works normal. So I checked my Imei and it showing up as 0 / 12 . Anyone else experience this and is there a fix for it. I already tried restoring my EFS folder but the two needed files are not there and I never made a backup.

I have this phenomenon on my SGS2, and have had it such since January after flashing an Embryo ROM. I'm not sure how it happened, I used to think Embryo borked it but no other users reported anything similarly happening to them.
However, I have no issues with data or anything else problematic occurring as a result of the IMEI being 0'd. Everything works fine. I use Straight Talk, so I think IMEI blacklisting doesn't apply to me, but it may be a factor in your case, as ATT/T-Mobile are more stringent now about EFS tampering etc. because they now blacklist handsets.
QPST or somesuch, a Squidbox, or Riffboxing type of repairs may remedy the problem. Try using a different SIM for another network and verify it's not a carrier specific issue. Also, try going back to stock and doing an EFS restore via the Service Menu from stock Dialer. (*#*#197328640#*#*)
Also, to save any trouble; Odin will not help you, as the EFS partition is handled seperately unless you check the box to clear EFS...which will also not help you.

1. Disconnect USB cable from phone.
2. Go to Menu->Settings->Applications->Development.

Incase you dont know the IMEI of your device, just check the mobile box or it is written in a label inside the mobile below the battery. Hope this helps...
Thanks guys, the imei showing up as 0 wasnt the problem everything works now. it turned out to be the proxy settings i setup for ad blocker was blocking data when connected to wifi.

I am having a similar problem. When I try the above *#7284# or *#9090# codes I can't get into the menu's to change the settings. I get a error that says,"mobile network not available". My IMEI number is bad and I can't get on the network at all. Is there a way to make this work?

Just take a backup, hard reset your phone and again follow the steps. If it doesn't work, just try to update or change the ROM and try again. Hope this helps.
When i was on a custom rom the debug menu wouldn't show up , make sure you go back to stock rom.

Error 16 - Switch ***

How to fix "ERROR 16 - Switch ???" on gs3 flashed to boost mobile.
This is what I did. Hope it works for you
Might work in other cases.
Take battery out of flashed phone.
Connect Donor Phone
test donor phone and see if you can connect (make a test call, try to get onlne)
if not <contact boost mobile>
if it does, then connect it to pc and get PRL form it.
Load QPST, under Start Clients menu, select Service Programming.
Click Read from Phone and enter MSL (000000).
Then Save to file. This will save a .qcn and .rl0 file.
In QPST, under Start Clients menu, select RL Editor.
In RL Editor, load your .rl0 file. Go to File, Save As..., make sure type is *.prl and enter a file name. Save file.
Turn off Donor and remove battery
Connect Flashed Phone
What You Will Need
The DFS CDMA Tool
Your MSL number (Sprint) or SPC number (Verizon, this is usually "oooooo").
Obtaining your MSL/SPC number is as easy as calling up your carrier and asking for it. They will freely give it to you. Other options include using the MSL Finder app. If that does not work, you are probably on Jelly Bean, so you will need to make a quick call to your carrier.
Step 1: Enable Use of DFS CDMA Tool
The use of this tool requires a non-standard USB connection (i.e. Download Mode, or just DM).
Open the Dialer and type in ##DIAG# (##3424#).
Click on "Qualcomm USB Settings" and select "DM + Modem + ADB" then press "OK".
Plug your device into your PC and go to Device Manager.
Locate "SAMSUNG Mobile USB Serial Port" and remember the COM number (in this case, COM5).
Step 2: Load Device into DFS CDMA Tool
Open DFS CDMA Tool. If you are using the Demo version, there will be a small countdown and the app will launch.
In the upper left-hand corner, hit the "Ports" button and select the port you found in Device Manger.
Double-click the port, and double-click it on the bottom to load your device into the software.
Enter your MSL/SPC number where it says "SPC" and hit the blue arrow. You should see the log show "Device Unlocked".
Step 3: Write New PRL
Hit the programming tab, then the NAM sub tab.
On the right-side, load the PRL that you want, then hit "Write".
Disconnect your device, go back to Step 1 and put your device back to "MTP + ADB". Back out of the menu and reboot your device.
Confirming PRL Change
Go to Settings -> About Device -> Status. Scroll down to "PRL" and confirm that it has been changed.
Take battery out of flashed phone. Again
go to "boostmobile" and login/create your account.
goto update handset
enter info for another boost phone (not donor, not flashed phone)
turn on 2nd boost mobile phone
go through the steps and test it for connection (calls, internet)
turn off and take out battery.
goto update handset again
enter info for Donor Phone (not 2nd Boost phone, or Flashed Phone)
turn on Flashed phone
go through steps, reboot
nJoy.......

Hi, if you get the error in step 13 test select Setting option> comport> and select the port to which you are connected again and give OK. Good luck
Hey guys, I will reactivate this topic a little. I ve got LG F180K and I converted it to E975 without doing EFS backup (still had imei number but no signal). I flashed modem for K and it still didnt work, flashed L modem and it...worked. No LTE and no 2G, only 3G, still imei.
What to do then if I want come back to F180K ROM? (NO EFS BACKUP)
If you unlocked using freegee the imei backup folder is their in your internal storage root folder. freegee backups even if you don't choose to.

Do this step for no signal if your IMEI is correct(not null).Root is necessary for this step
Install "SQLite editer" from Google play to open "settings.db" in location "Data\data\com.android.providers.settings\database s" select "global" -> find "subscription_mode" change value "1" to "0" then save and exit.

i have same problem due to convert f180k to e975. i have solved it by factory rest after flash and after factory reset (setting->backup and reset-> reset phone) restore IMEI and then again factory reset.
Factory reset after flash is main solution.
Sorry for necroing an old thread, but my lg g6 t- mobile h872 , suddenly says IMEI null after the latest 20a-e update. I never rooted, or flashed any custom roms before
What should I do?
