Request : Message Center Number Update App

Is there any App that can allow to edit the Message Center Number for SMS? I tried *#*#4636#*#* trick to update the number but my I could not "+" to the number. Even when I enter +13123149810, it gets changed to 13123149810. The only way I could change the number is by overwriting the file com.android.mms_preferences.xml (with + in the number). The problem with this approach is that any time I restart the phone, this file gets overwritten by default and I have to again copy the number.
I am on GB. I had the same problem on Froyo also.
Any help would be appreciated.

How To Upload ERI using Revskills
Manual Method / How This Works
The IMEI part is complex and I wont go into detail on that at all. If you dont have access to a windows machine, then I'm sorry but most of the avail tools that will allow you to repair IMEI is going to be Windows based and you can use a virtual machine. Not with my tool but others. This is mostly going to be focused on the ERI it self.
The ERI is binary file that is stored on the QCOM chipset, this is the primary file the "Radio" and the device use in order to determine certain functionality of the device.
This is stored as /nvm/eri_0 on the QCOM's EFS. You can use QPST EFS Explorer all though it will probably crash, or some other EFS explorer for Qualcomm chipset's.
I have uploaded the original eri_0 file to this forum. All you have to do is download it. User QPST or Bitpim, Revskills, and upload the file to /nvm/eri_0 you can leave it's permissions as 666 or chmod the permissions to 777 your choice the phone will read it either way.
The /nvm/eri_0 that is uploaded to this forum comes from a stock s3, although its the same ERI file Verizon has been using forever. Thats all this tool does. Simply fix's the IMEI and uploads a good eri file to the correct directory.
Questions and Answers
Q) Do I need to do anything special first like back up any part of my phone or anything ?
A) No, as long as you can enable diag port you can restore your IMEI, just look on the back of your device under the battery for your original IMEI. I STILL ADVISE YOU TO BACK UP using this method here http://forum.xda-developers.com/showthread.php?t=1852255
Q) Can this change IMEI?
A) Its purpose is not to change IMEI doing so is illegal and any talk about changing the IMEI will be reported and you may be banned. I advise against it as it could cause unknown issues.
Q) Can you share how this works.
A) No, sorry my position, my family and my job comes first and this would put me in a bad position.
Q) Can you just tell me in pm.
A) No so dont bother asking.
Q) My phones says Roaming and show roaming icon will this fix it ?
A) Yes this should be able to fix that issue, it does that by uploading the ERI back to the QCOM chipset.
Q) Should I / Do I have to donate ?
A) No, you don't need to donate, and I don't want you to fell you need to. Your donation could go to something else EFF, Adam Outler, XDA, Poor kids in any country, some other foundation. If you feel you would like to donate to me you can, I wont stop you and I wont ask you to.
Credits
Not sure who all to credit if you feel your name should be here Just tell me and why and Ill post it here. I did not read any of the other forum really, but ill list who i have seen and who as helped me identify it was the ERI
Also no particular order
Adam Outler - For everything he does, I watch a lot of his videos.
WildZontar - For his thread, not sure if its his info or just info collected. - http://forum.xda-developers.com/showthread.php?t=1852255
TrevE - For what he has contributed, looks like a lot very knowledgeable person
Jay Evans - For doing the initial tests
BillBauman - Discovered the missing ERI
GerardAnthony - For the AOSP mode scripts
Again, for these people as well, I didn't read the whole thread etc to see everything they contributed. If someone would or if they would / want me to update it please ask to me to update so I can give credit where its do.

better to flash rom again
1. Download KDZ http://lg-phone-firmware.com/index.php?id_mod=19
LGT/LG U+(KOREA) V20d LGF160LV 891.35 MiB or
LGT/LG U+(KOREA) V20f LGF160L 878.34 MiB or
LGT/LG U+(KOREA) V20g LGF160L
2. Download Attached ZIP file http://www.mediafire.com/download/04n6a99dp8gq5zh/unbrick_lte2.zip
1) Download the latest KDZ for your phone
check link in attached file
2) Make sure you have LG United Drivers already installed, otherwise download from below
*LGUnitedMobileDriver file in attached zip
3) Download LG KDZ Updater
KDZ_FW_UPD_EN folder in zip
4) Download the manual adb wipe batch file
wipe in attached zip
5) Put your Optimus into Download Mode by switching it off, attaching the usb cable to the phone, holding both the up and down volume buttons at the same time and lastly inserting the usb cable into the computer; wait for the drivers to finish loading if doing it for the first time.
6) run KDZ_FW_UPD.exe. Use the settings below
Type: 3GQCT
Phone Mode: CS_Emergency
KDZ file: navigate to the folder which you have saved the downloaded KDZ from the step (1)
Click Launch Software Update and wait for the flash process to finish
7) Your phone will restart itself when IParam = 90 is displayed and proceed slower until you see IParam=1 again (which signals the end of flash, you can safely exit the program then and remove the cable from the phone). If phone boots up normally, congrats, skip the steps below and proceed to use the phone as per normal

How to fix LG G2 with IMEI issue

Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.

You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

I've tried the this guide and it didn't work for me. I get an error when I try to write NV. The good news is that I don't have an immediate need to change/fix IMEI but I was wondering if it ever gets zeroed out I have a way to restore it. I will give your tool a try.

So the EFS Professional is compatible with phones other than Samsung? Once I've unzipped the file I see a bunch of binaries for Samsung phones, but nothing for LG G2. When I try to run it generates an error the app is for Samsung devices only... Where can I get a compatible binary for LG G2 or EFS professional that works with LG G2?
I've tried Qualcomm NV Tools instead of EFS Professional and I cannot create a backup. When backup is being created it errors out saying the device has been disconnected... Also if I write the IMEI it says it was accepted but it doesn't change.
PS: I should probably start screweing around with these apps since I may introduce the problem. My IMEI is fine.

Imei will only write if zeroed out. You are correct, EFS Professional is for samsung devices but the Qualcomm NV Tools is universal. I am currently in the middle of updating it so more features can be used on other devices.

19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.

Hey kingroach, amazing guide, wonderful!
I followed everything step by step. Right now I have some generic IMEI which does not work, I'm trying to write my original one back, but at step 20, when I click "Write NV", the numbers change, the Hex unchecks and the popup comes out. When I close it, Hex goes back to being checked and numbers return to what I made them. and I get this popup:
Here's a video.

You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

Hi, thank you for your help too in these threads. I tried EFS Pro, everything checks out, it says IMEI written, but when phone is restarted, nothing has changed. Do you know if EFS Pro need some other setting enabled to actually change the IMEI?

Try deleting 550 nv item which contains the imei and save. Restart the phone and add it.

I couldn't - you try with the custom list, under tools I think. You move item 550 from the right column, and it dissappears, but when I read NV phone items, its there. It's untouchable I tell you!:silly:

Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.

Did you first reflash the stock rom? Someone was getting similar error and flashing stock rom fixed it.

thanks,i was able to change imei,but still can't register on network?any possible solutions?

Go to
Settings/Mobile networks/Network operators/Search networks
And choose your network
If didnt work try to flash your mobile with latest Rom using (smart switch) keep in mind you will lose all data on your phone if didnt work try Marshmalow beta....any way try roms and do same steps...

i can change imei easily with your instructions provided,but serial number? ( it works for me i can change my imei to whatever i want to....S/N is easy only modify serial_no file inside \efs\FactoryApp ) <<<<could you explain this? my emei seems to be finally corrupted so only way to get it back is write in id changer manually,so do i need to backup and restore it anyway?

Dude just restore this efs backup with twrp recovery https://www.mediafire.com/?loh80547x1k5cg8
It will say null or something then try to fix imei with apps inside folder...if this didnt work visit repair place...

Sincerely hope you're not in the UK as it's very illegal here to change IMEI and advertising the fact isn't a smart move.

Greetings,
Changing IMEI is illegal in many countries and the discussion thereof is prohibited on XDA.
