[A] Simple Mobile APN Problem fixed

Okay, here it is as promised. You need Clockworkmod Recovery installed but you don't need to be rooted to flash the zip.
I have created a flashable zip file to replace the stock apns-conf.xml with one that has settings for Simple Mobile. What I have done is made an apns-conf.xml file that has settings for virtually every gsm carrier worldwide with the main TMO settings changed to Simple Mobile settings. I wanted to have it backup the current one also but the Edify scripting language used by Clockworkmod Recovery doesn't have support for moving or copying a file. So if you want to back up the file first there are two ways. If you are rooted just use 'Root Explorer' and copy the file and then paste it back to the same directory (change to R/W first). The backup will show as apns-conf-copy.xml. The other way (root not required) is to connect to the phone by ADB and issue the following adb command:
> adb pull /system/etc/apns-conf.xml apns-conf-backup.xml
[Make sure the directory you are issuing the adb command from is not read only and you have full modify permissions if you are using Windows.]
To restore the file you can just use Root Explorer to delete the new one and then rename the copy back to apns-conf.xml. If you copied the original to your computer using adb then just change the backup to apn-conf.xml and use 7-zip to replace it with the one in my zip file and flash the zip package again. That will restore your original file.
I made two flashable zip packages. Both are flashed using Clockworkmod Recovery. Put the desired file on your internal or external sd card and flash it, then reboot. Afer rebooting go into Settings, Wireless & networks, Mobile network settings, Access Point Names. Click the menu button and then select "Reset to default." Then select the radio button for Simple Mobile to turn the selection green. T-Mobile will still show but the change to Simple Mobile should be persistent even if you shutoff or reboot the phone. If you change the sim you might need to select the Simple Mobile apn again (only first time). This apn setting is for internet and mms with Simple Mobile.

apns-4-GB-stock.zip Restores the stock Gingerbread G2X file which has no settings for any carrier. TMO, Wind and Videotron are set elsewhere in the rom.

I tested this myself with an old T-Mobile sim I have. It worked and the change was persistent after rebooting and shutting off the phone.
This should fix your data connectivity problems.
Please note: If you have a stock rom this will prevent future OTA or LG Updater updates. Use the "apns-4-GB-stock.zip" to restore the file to stock GB T-Mobile G2X and then OTA and LG Updater updates will work. If you have a stock Froyo rom use one of the methods above to backup your original file so you can restore it later if you want to get an OTA or LG Updater update.
Enjoy!

THANK YOU
Hi jboxer,
Thank you very very much.. Its been quite a while I did adb and stuff the last time I did it was with HD2 last year I need to refresh my skills..
Anyways the phone is not with me and I will go home in the evening and try this fix and let you know..
Thank you very much for such detailed steps and description.
I will let u know how it goes as soon as I try it..

It would have been nice to get some feedback after making the effort to fix this problem for you Simple Mobile users. anush.isaac, you said you would let us know as soon as you tried it out and we have been waiting four days now for your update.

question: What is APN? What does it do, and why does it need to be fixed. Sorry noob question. Im slowly learning about the android system. Some feedback would be nice. One more question: This works on T-Mobile???
*edit I just googled it.......can someone explain it to me in english, lol. I felt like I was reading in a different language.

Have the Same Problem
Hey all,
I was reading up and I have the same problem with my G2x.
I would like to try to use the solution that you provided but I have never done any rooting or modifying to my phone. I am not sure how to install the clockwork mod that you mentioned.
I only have access to a mac and in my experience that usually stops most attempts to modify my phone or other phones.
where can i find simple instructions on how to apply the flashable zip package and perform the Adb (not sure what this is)
Thanks in advance,
RR

Well you have to touch the radial button where the green dot should go, however, that is not good enough. You have to hold it down for awhile. Just the button. Then you get the green activation dot. There you have it.
Thanks for the help. You were correct, as was my assumption.
g2x activation at simple mobile.
Simple Mobile website--> Enter in Android config on a new APN--> Save and hold down the radial button long enough for it to turn green. From there, internet, gps, mms, etc. all work.
Ocean .. you are AWESOME. it worked like a charm , i kept searching around until i found your post, i'm gonna post this in another thread on here about the same issue if you don't mind. i'm sure many people are experiencing this issue
glad i didn't have to root ..why? my name says it all
ps. just make sure you do the drag first a couple of times "it wont actually drag the dot" but just do it a few times then hold like Ocean said until it turns green , i held it for 15 seconds at least

Sorry

Hi jboxer,
I really apologize for not being able to get back to you quickly. I was help up at work for the past few days and could not try anything.
I have not Rooted a G2X before and I am a little concerned on how to do it. I did read the Instructions on this form but it is a little confusing. Let me confirm this with you, To apply your fix I know I need to Root the phone but is there another way without rooting the phone as I am afraid I might brick the phone.
Also In order to root the phone I followed this link http://forum.xda-developers.com/showthread.php?t=1255214 . So I just need to install the CLOCKWORK MOD RECOVERY and flash the root zip??
The phone is my Girlfriend's so I don't have access to it all the time.. I once again apologize for the late reply..

No, you DO NOT need do root the phone to apply this. I stated that in my original thread and in others. You just need to install Clockworkmod recovery, boot into Clockworkmod and flash the APN zip and follow the instructions to restore to default apn settings. That's it. If you want to root then you can also flash the root zip at the same time or another time. The choice is yours and solely up to you.

Thanks
All day I've been trying to get the correct APN set up..and I come across your easy flash zip. It worked fine on my G2x and I have data! Thanks

Glad to help. Please click me a Thank You.

I've installed the zip and have followed the instructions over and over again, but somehow it keeps dropping out. i just upgraded to GB today (should have stayed with FY). the apn just keeps resetting to TMO over and over, my phone is completely screwed on data now thanks to GB. either way, anything you think i can do about the anp issue?
it just keeps failing or saying the connection timed out.

If you install my APN zip file the problem should go away. Once this is installed the APN has the same status as the TMO one so the phone should not want to switch back to TMO any more.

Im gonna give you guys another solution that does not involve flashing anything. I had this exact problem and here is what i did to fix. Blv me after you read this you wont believe it. Plus with the described methods in this forum about this issue, if you ever have to reset your phone, you will be back to the same problem again...having to flash that xml file.. read on..
First you need to get an unlock code for SIM unlock. I paid $2.80 on ebay for unlock code from unlock_fusion. Really cheap. You will not be able to create and save a new APN without the phone being unlocked. Now the default APN in the LG G2x is "T-MOBILE US" and you cannot delete it. Even if you root or unlock it cannot be removed. If you create the simple mobile APN as described in a matter of minutes it switches back to the tmobile APN which is a real pain in the a$$. The simple solution is to create another APN and name it exactly as your default APN which is "T-MOBILE US". Viola! Dont worry, it will allow you to save it with the same name but inside that APN you have the simple mobile configuration. It works without flashing anything. I added one thing extra to the simple mobile config APN type: default,mms,ota,agps
Thats it. you dont really have to add that but I did.
Note: This problem shows up after updating to android 2.3.3. before that, a simple unlock and adding the simple mobile APN worked fine.
Note:
to unlock requires that you put a sim card from a different carrier other than t-mobile for this phone. Also using the simplemobile sim card wont bring up the screen that asks for the sim unlock code. Use an AT&T sim card.. just borrow one from a friend. For those of you that dont know, simple mobile is what is called an MVNO (mobile virtual network operator) of t-mobile. They resell t-mobile's network which is why your 3G and 4G still works on simple mobile or any t-mobile phone that is used on simple mobile. You can also use a sim card from h2owireless as they are an MVNO of AT&T. So with that said, insert a different sim card and turn on the phone and you will see the screen come up asking for the unlock code. Do not enter anything that is not a real unlock code as too many tries will lock you out.

Found a fix that worked for me.
Nothing listed here fixed this issue for me. I eventually ran across APN Manager on the market. It works with root access and gives you full control over the APNs. I just made a backup then deleted the T-Mobile default one and now only Simple is there and always active.

John,
Funny its only you with that problem. Ive helped so many friends with this phone and the same problem and its resolved with what i posted. No root access needed. Only unlock code required and its cheap enough. Did you get unlock code for your phone? because you cant do what I posted (see picture link in my post) with out unlocking first. Please post exactly what changes you made because i dont think there is a root solution for the G2x/android 2.3.3. Post exactly what you did in the app you installed. thanks

I have discovered this is a framework issue also. I can make you a new framework and build.prop that should fix this issue once and for all. What rom are you using? I need your framework-res.apk file and your build.prop. I can fix them and make a flashable zip for you to install.

How-to: Backup and restore your IMEI / MEID / EFS Data

EDIT:
THIS SHOULD NO LONGER BE USED.
PLEASE SEE THIS THREAD FOR RECOVERING YOUR IMEI - http://forum.xda-developers.com/showthread.php?t=1802024
Hi guys,
I tried flashing AOKP on my S3 yesterday and had my IMEI value set to zero, a rare(ish) error that some users have been running into with AOKP and the unofficial Cyanogen builds for this phone. If your IMEI is lost and you don't have a backup, your phone is basically toasted. So, I had to get my phone replaced which wasn't much trouble.
After speaking with invisiblek we determined a way to back up the EFS partition (which is where the IMEI and MEID is stored).
You need to do this on a rooted phone, it's been tested only with root66. You need USB debugging on and adb on your computer.
Code:
adb shell
su
dd if=/dev/block/mmcblk0p11 of=/sdcard/efs.sbn
(exit adb)
adb pull /sdcard/efs.sbn
DD is a linux utility that can be used to copy data from point a to point b and many, many ways. What we did here is copied the EFS partition to a single file (and then copied it to your PC). The efs.sbn file was about 13.6mb, but I've heard reports as low as 10mb. We can reverse this process to restore as well:
Code:
adb push efs.sbn /sdcard/efs.sbn
adb shell
su
dd if=/sdcard/efs.sbn of=/dev/block/mmcblk0p11
reboot
This time we wrote the backup file to the EFS partition. After doing this you need to dial *2767*3855# to re-provision your phone.
My experience: When installing AOKP, my IMEI was replaced with most of my MEID, even after reverting my rom to root66. (This causes mobile data not to work). After restoring my backup and provisioning, I regained full functionality of my data and phone. I haven't had a chance to try this with a phone where the IMEI is set to 0, but I think it's safe to assume this would fix that as well.
I would HIGHLY recommend making a backup before doing anything to your phone. Making a backup is read-only is poses no chance of something going wrong.
EDIT: For clarification: If your IMEI is already messed up, this will NOT get it back. You need a backup from BEFORE it was corrupted.

Can we run this in Terminal Emulator to get the same output? Last time I tried ADB on this phone I wasn't recognizing it. Could have been my computer though. ADB devices came back with no attached devices last time.
Looks possible. Your just telling it to save that file to the root of the internal SD and then telling ADB to pull it. Don't see why you couldn't save to SD then just Dropbox it or something.
Edit: Did it in Terminal Emulator. Saved to SD. Uploaded to Dropbox. Will also hook up my phone and pull it that way. Looks like pushing will work the same way as long as the file is on the root of SD.

Thanks so much. I also ran with terminal emulator and backed up.
Hopefully someone can verify that this will work with the IMEI = 0 issue, as that will allow us to continue to flash!

Worked for me in Terminal as well. Zipped it up and emailed to myself. 13.6MB

so I have a question about this -
I flashed CM9 the other day and it was taking over 20 min to activate and I did a battery pull, then I restarted and it activated just fine.
then i started reading all these posts about how that will break your IMEI and it got me wondering because I no longer get 4g, I get 3G just not 4G.
before I did this my MEID read the same as my IMEI but had less numbers. (just like 2 or 3) after doing *2767*3855# go back into status and see that I now have HEX and DEC under MEID which I did not have BEFORE the *2767*3855#
my question is - is there a way to test the 4G some how - I checked VZW site it says I am in a 4G area, is there a number of sort I can look at in status or somewhere else on my phone?

I'm new to this can someone tell me would in use those same commands on terminal emulator to get it? And I'm on unofficial cynogen right now so my next question is if I do corrupt it how do I place the imei back to get it woeking? Thanks

If using terminal emulator just skip straight to the line that has "su" on it and go from there. Same thing when putting it back in after it gets messed up.
The key is to put it somewhere safe as it will store it on your internal sdcard. This is called "sdcard" on your device. I just sent a copy to my drop box.
If it gets mesed up, then I would Odin back to stock rooted and just take the copy you have stored somewhere other than on your phone and put it back in the "sdcard" but not in any folder, just in the root directory. Then simply follow the restore directions in the OP but skip straight to the SU line.
That said. I'm still waiting until the RIL gets fixed. TW isn't that bad and with the mods and replacement launchers and apps the phone is nearly stock anyway. I'm being patient.

Download the "Phone Info" app and see if you can change it to get 4g again. if not, you might wanna try restoring back to stock using ODIN to see if that helps.

One of the more helpful posts I have seen to this point (provided it actually works to recover lost IMEI's). This issue was probably making many people hesitant, having a safeguard is always good. This is also extremely easy to do.

I flashed CM10 on my S3 from the rooted Bean rom and I can confirm that with a clean install my IMEI is missing and I have no "own number".
I do however have working data, phone, messaging. Could you explain what you mean by a phone being "toast". Is there some other consequence I'm not seeing yet? If I go to another rom or back to stock is my phone going to brick?
I've seen bits of pieces of info about the missing IMEI, and I'm hoping somebody can clarify what this means for me since my phone is technically working as expected.
Thanks

Sorry I just wanted to clarify. My IMEI is existing, but "My phone number" is blank. Also something called "MIN" is blank. I have been getting a popup asking me for a sim unlock.
Sorry for any confusion. Please ignore if i'm derailing the thread. It just sounds like a similar issue.

Worked using android terminal, on my ATT S3. Nice to know I have a backup -- eases my mind just a bit.

Well, a couple of things.
1. I'm on TMo
2. I'm on CM9
I have two phones...one borked and one good.
Went ahead and tried this..when I did the re-provision thing I got an error Connection problem or invalid MMI code. I assume that this is caused by being on TMo.
Bottom line, my serial # is for the correct phone, and this did not move over my IMEI from my working phone. My borked phone still shows IMEI 0

As per the OP, it makes sense that it didn't work for you. We need someone with a valid backup to test this theory out to see if it restores their IMEI.

You did do a reboot after attempting to restore correct? Keep in mind, Verizon due to it's dual type of network (CDMA/LTE) has that extra need for the provisioning, thus the code they use to activate is needed. Remember we use GSM, there is no special activation needed except pop a SIM in and power up. Try putting your SIM in the old phone and powering on.

I don't know where to find that file, but i do know that no such app exists for SGH-i727(r). You have to manually unlock it.
There is a guide that tells you all about it here.
On a sidenote, next time please use the search function of this site.

So to clear up some confusion you'll only find NV.data_bin on vibrants. It was an exploit used to unlock them. The file was SUPPOSED to be encrypted. On the Vibrant it wasn't. It was hidden in plain site in the EFS folder under efs/root/afs/settings. From there you could use a hex editor to read the file then unlock it. Samsung has gotten wise and now hides that file. So there you go.

Thanks alot, so i need to find "Tmo_SGH-T989_UVLE1_radio.zip" then unlock it then switch back?

No, there is no current method to decrypt the efs, only to restore (encrypted) backups if necessary. Besides, we already have an unlock method based on ucld2 service menu.

Thanks alot for all you help i found that section and the links you provided. Im running stock ICS 4.04 and i just downloaded your modems-ucld2.zip you provided. Im gonna flash in recovery and see if it lets me unlock my i727. my whole thing is i see people saying just flash it back. Thats just where im confused. When they say flash it back and it should stay unlocked, do they mean restore from the backup that im making, or use the other link (ULCD2-oem-rooted) that you provided to restore.

Once you follow the steps and unlock your phone it will remain unlocked. The unlock will persist through ROM flashes. So flash or restore whatever you want.

Thanks everyone for all your help
After following the directions my i727 is now unlocked and working on t-mobile. wow im amazed at the download speed with t-mobile hspa 16mb/s down and 5mb/s up
Thumbs up to everyone

[GUIDE][TO SOLVE] MTK No IMEI, No Baseband, No Backup?

Guide - To Solve MTK Devices ~ Soft Bricked from No IMEI, No Baseband, No RIL, No WiFi MAC, BT MAC, comms etc. ​
Note:
This is a "clone thread" from my original thread. I post another guide at here to help those who are in difficulty finding the correct guide to solve this problem. This method probably works on all Mediatek devices. For reference, my Lenovo P780 uses a MTK 6589 chipset.
DISCLAIMER:
*What you done to your phone is at your OWN RISK, you choose to do this modifications to your phone and don't blame me if anything goes wrong.
Preface:
Recently I have noticed many people who tried to flash Custom ROM's on MediaTek devices and causes the phone to lose IMEI, Baseband, RIL, WiFi MAC, BT MAC, SN, comms etc. and causes connectivity issues (including me), which renders our MediaTek devices turned into a "AndroidPod" media device that cannot make calls, SMS etc. As an example, my Lenovo P780 which faced the exactly same problem.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
See the IMEI and baseband are still there in factory mode!!!
What could cause this is problem to occur is probably during ROM flashing process, the installer probably wiped out the /data/nvram (folder/partition). The /data/nvram (folder/partition) is the heart of your phone of all communicating feature, if the (folder/partition) is corrupted, just like I said, no communication features.
*Actually the baseband is there, but because the /nvram (folder/partition) has corrupted, the Android OS were unable to recognize it thus showing Unknown.
So no backup = Phone dead? Nothing but a media player?
First step, ensure your phone:
On Stock ROM
Rooted
PC have ADB drivers installed (If you don't have it please ask Uncle Google :good
Well, that isn't true, recently I found out, the phone can actually be easily recovered (on most MediaTek devices) and gain at least those comm features back by simply delete the whole /nvram (folder/partiton). If your phone coldn't recognize SIM card, wait a while after deleted the folder, your phone should have signal after maximum 10 seconds of waiting.
*In most of the cases MobileUncleTools give AT command failed to send probably the /nvram folder is corrupted, simply delete the NVRAM folder and reboot will do.
For WiFi MAC address fix (WiFi NVRAM WARNING: ERR 0x10), because the solution already been posted, so please click here.
Bluetooth MAC address fix: Firstly, using any File Explorer with Root abilities navigate to /data/nvram/APCFG/APRDEB/BT_Addr and also a BT_Addr file under /data, then copy both files to your PC. Then open up the file by using Hex Editor (HHD Hex Editor). To fix a static MAC address, just simply type in your MAC address on the first row (0000) from column (00-05). That is what your MAC address should be (Edit both files with the same MAC address). After you have modified it, put it back in the exact location and remember to change permission.
Actually you can also get restore your IMEI, WiFi MAC, BT MAC, SN by restoring a backup created by MTKDroidTools with other exact same model as your phone.

Hi,
I have a Pomp W99 (MTK6589T) and it seems this model (or it's software) has the problem, that Wifi and Bluetooth MAC address changes on every activation.
While I was able to fix the changing MAC address with the procedere as described I still have the problem of the changing Bluetooth MAC, which is very annoying.
Any ideas how to fix this?
Thanks & Ciao, Alfred

Thanks for this but sadly, this doesn't work, I've already tried it.
I have a BT_Addr in /data/nvram/APCFG/APRDEB but the mac address there is not used.
I also have a BT_Addr in /data and it seems, this one gets updated with the current MAC.
I tried removing the file rights so that the file could not be altered, but now I have a static address in the file that is different from the one shown in the telephone status.
I'm still getting on every enabling of bluetooth a new address, always like xx:xx:46:66:xx:xx (the two bytes in the middle ar always the same).
My only solution at the moment is not to disable Bluetooth and not to reboot my phone, because else I have to re-pair all bluetooth devices.
I would even be lucky with a solution that would change the bluetooth MAC to static one by script after enabling Bluettoth but I couldn't find anything about this, all I could find was about changing wifi MAC address.
Maybe you have another idea?
Thanks & Ciao, Alfred

Or you can try editing both files with the same MAC address? Save and set permissions?

Been there, done this.
Both files have the same address and permissions are set so that they cannot be altered.
Still the OS keeps creating random addresses, so it doesn't seem the files are read by the system but only get written.

Well that's weird, technically it should be static already. Never mind, I will keep searching for other solution. Sorry for that you can't get it to work.
Or perhaps, do you have any friends / relatives of yours using the same phone? You can try MTKDroidTools to make a NVRAM backup of their phone and restore the settings to your phone. That should fix it.

I get something like that after a STAR N9002 Update, but with something else...
My touch doesn't mach the screen, the screen is normal but the touch point's are out of place... do you understand? like the touch have a resolution diferent from the screen resolution...
Do you think this is caused from a software problem, NVRAM is missing and happen all in the same reboot AFTER the update...
I'm trying to get a backup copy of NVRAM, but I don't know if the touch will be ok after that...
Thanks.

I know, I have encountered the problem before on a cheap China tablet. That isn't caused by /nvram corrupt/missing but the touch driver you have are not compatible with your touch hardware. I'd suggest you restore from a backup.

Thank's for your answer. I've already get a NVRAM backup to set me up. That's ok, but the touch is still messed. I don't have a backup... I don't know how I will get it...

Do you have any friend's or anyone you know using the exact same phone? My idea is: Find an 100% identical phone (probably from dealer is the best bet). Backup the entire phone using MTKDroidTools, and then restore the backup to your phone. After that just restore back your original /nvram partition (you wouldn't want the same IMEI and related info isn't it?)
Therotically your phone should work/recover.

Yes, I'm waiting for a promised integral backup. That's my final hope now...

Okay... Good luck bro. Next time if you hands-on with any MTK devices. Be sure backup it first using MTKDroidTools. It's a very useful and powerful backup software.

No luck for me.
Even a full backup did not make the touch work well.
I think a backup is a good way to prevent flash problems, but what I have was far worst than that. Some how, the flash procedure burn the touch driver chip, and there's no way to make them work again...
I'll have to replace it... that's a shame...
Thanks for your support.

(SOLVED) Help Restore Lost IMEI & Serial No (SM-G920FD)

Hi, can someone guide me as to how I can restore my lost IMEI - Serial No back to stock? using SM-G920FD (duos)
Kindly refer below to the details of my problem and actions done.
How the issue happened
1. I'm currently on stock firmware of SM-G920FD (COH8). (Local copy of COH8 flashed via ODIN)
2. I received an OTA update (COI9) and installed it. Phone works perfectly fine.
3. After doing some tests on some kernel (arters97's kernels), I have decided to revert back to stock firmware since the kernel uses Note 5 gpu driver (not knowing that someone has prepared a flashable zip for S6 flat/edge) :crying:
4. I use my local copy of COH8 and flashed via ODIN. The flash failed thru sboot.bin - that tells me the bootloader is outdated on my phone *ugh.
5. I downloaded COI9 firmware from samfirmware site and flashed it via odin.
6. It is now stucked at first samsung logo. After going to recovery it says cannot mount /efs
Fixes I made
1. I dont know much stuff with efs thingy, that's why I didn't do a backup for it.
2. First fix, (this is the worst step I ever made - that costs me into this big trouble) I installed a "something" application that requires me to format the efs partition. Well done to myself, the app successfully wipe it all without backing up efs .
3. Now the phone is stucked to samsung first logo. Period. Even Reflashing stock via odin failed. Realizing the efs files are all messed up.
4. Now, after searching thru forums, Ive come into this adb command by running this, .
/system/xbin/su
mke2fs /dev/block/sda3
mount -t ext4 /dev/block/sda3
After doing this, Ive been able boot into device, I have a working WIFI, a valid ip address.
a. no bluetooth address
b. no imei for both sim 1 and sim 2
c. Incorrect Serial Number
d. No network of course
After deep searching thru xda, Ive come across with nv_data.bin editing thru Hex Editor. It could probably return my IMEI and Serial No back to normal(i still have the imei no & serial at the back of my phone ).
Perhaps, the only way to fix this will be on a repair shop to fix my imei. I doubt my samsung warranty would help since Im constantly flashing stuffs on my phone.
Can someone share me their full EFS folder zipped with Galaxy S6 SM-G920FD / G920F (probably a single sim will do) so I could compare and edit my own imei that would be a great help and I'll give a feedback asap.
Hoping someone can help me on this. Thank you

Anyone?
37 views of galaxy s6 owner and no one dares to share their efs

There is loads of information on the forums to recover lost IMEI. Did you try flashing a modem and bootloader update. This should generate the efs folder with nv_data.bin. You still may not have the correct IMEI and serial in the nv_data.bin, but at least you can edit it.
Search the forums I have seen loads and loads of tutorials for this problem.
Not many people are quick to give out there IMEI.

No, modem and bootloader flashing does nothing.
I do already have a pre-generated-stock nv_data.bin from my efs folder.
Can you give me an example of a working thread that requires editing of nv_data via editor that works?
The problem is that their issue has worked specifically on their device, none of the Galaxy S6 users were able to do that afaik. Almost a week since i started searching for answers but to no avail.
For example this, the thread below says that I should goto this address [offset] 00188008 but in my Galaxy S6 nv_data.bin, the file is only up to 000FFFF0 offset?? That's why I need help from others to at least share their fixes or comparison of this thread below with their nv_data.bin file. If there is similarity. Forget sharing your imei to me, but maybe you can consider how am I supposed to do that fix on the other thread.
Thanks
http://forum.xda-developers.com/showthread.php?t=881162

Or if someone can find their IMEI code in nv_data.bin, kindly share to me the offset (location) of the IMEI in hex editor. That would be a good start. Thanks

I can't remember exactly the offset location but I have seen it on my phone a few weeks back. I do remember seeing a few tutorials on YouTube. I will take a look tomorrow and if you haven't it solved by then I will help you fix it....

Thanks, hoping you could help me on that.
Something is weird on how efs is generated. I backed up the messed up nv data from efs folder. Then I deleted the contents of whole efs folder then reboot.
When phone booted, to my surprise I notice that it still generated the contents of efs. Then I compared the Newly generated nv_data to my backedup nv_data. No difference -_-. Still incorrect imei was given to me. 350000000000006 format both for sim 1 and sim 2.
Phone Info app says that my imei info (www.imei.info) was from an apple device rofl.
Since its giving me same and same imei and no product code/serial code
I suspect that my IMEI was generated from embedded hardware/chip??? But i think its not possible to mess any of the hardwareparts from flashing custom roms/zips/stock firmwares alone?

Hmm I think there's no chance for it to recover? since it is always giving me Generic Imei
One user says that it could be the hardware is somewhat corrupted or cant be modified blah blah

You showed your edited IMEI on your phone, but you didn't share how ?
I think this is what Im looking for, but HOW???
1. What is that cert file? Can it be installed via phones system files?
2. Does it need third party app and a toolbox hardware to buy and install? It smells like its for technician part already :|
3. Since it needs key cert, how can I generate this? Thru the 3rd party also?
But FYI, Im not into modifying IMEI as it illegal, what I wanted to do is to restore my device's IMEI found at the back of my phone.

You have now lost the IMEI
If you still have flash the firmware is invalid
I think no way to restore the original IMEI
If change IMEI is illegal in your country, it would be a sad thing

ugh. Based from your pictures, you used 3rd party hardware tool and app something like octopus box and the likes.
You're telling me to give this to technician, as it is the only way to fix my issue?

Changing IMEI i.e., frying someones IMEI to hacked/stolen/blocklisted phones are definitely illegal.
Back to my issue, did you send your phone to technician/ did you have the box tool to flash cert files to your phone?

Yes the octopus can do it

My English really bad, I speak a little bit more simple
If you don't have a backup EFS and your mobile phone and lost IMEI.
The solution is to use the BOX to write a new IMEI so that you will get a new IMEI
You write a new IMEI may and other mobile phone to repeat After doing this You will forfeit the warranty In addition to Will not affect the normal use of your phone
Samsung CERT is unique And only CERT must be the truth

Well still thank you for the replies, only repair via technician is the only way . Requesting for mod to close the thread. No way the imei can be reverted back via EFS - NV way, flashing stock modem, backing and restoring efs, mke2fs thingy, flashing stock firmware and so on.
There is part on the chip of the phone that literally erases the phone info for my s6.
If any can give other ways before I let go HAHAHA, but please refrain from efs,nv_data,flashing stock stuff, as the firmware doesn't have to do with restoring efs. Only the hardware device stores efs info for our phone.

If your phone is KNOX 0 x0
Then you can look for samsung to solve for you
I wish you good luck, my friend

Thanks , haha but my knox is 0x1 already

Tried to bring it to a legit 3rd party technician and they assigned a new IMEI for my phone and its working fine now.
imo I brought it first to Samsung and tells me that my warranty is void, but they can fix it via hardware replacement and would cost me at around $350. Lol no way!!!
For those who tried to do anything when all methods do not work, frustrations etc. This is the quickest way to restore it.
But thanks for the info I got from XDA members, now Ive learned that the first rule should be applied whenever possible before its too late.
To all other Explorers/newbies/Risk taker out there. Remember this one word.
BACKUP!!!!
Thanks.
