Hi. So here's the thing:
I was trying to unlock my Samsung Galaxy S4 GT-I9505 and I kinda messed up. I chose the DM/DUN/RmNet over HSUSB option from the *#9090# where it said that all NV data will be erased, and I chose YES. Then after reboot, I didn't get any signal from my carrier. I've tried other SIMs, but nothing changed.
Then I found out that I needed an EFS backup or something like that, which unfortunately I didn't make.
I tried flashing the original stock rom (MDE), but nothing happened. I updated the rom to MDM, but then the baseband version became unknown and the IMEI number became NULL. So I flashed the MDE rom again and I got the IMEI and baseband version back. Then I tried to root my phone. Root was successful, so I tried to use EFS Professional. I backed up everything, and restored but nothing changed,
I know the phone reads the SIM card because I can see the SIM Toolkit change to the carrier's. The problem is I don't get any signal.
Can anyone please help me?
Did you ever get any info or help with this?

I did the same thing. I did make a NV Backup. Copied them back but that didn't change the no signal problem. I have tried odin back stock root and unrooted. Some how you have to get out of the DM/DUN/RmNet over HSUSB setting and back in DM/DUN over HSIC but I can't find a way. Can you get into the *#9090# without it being blanked out settings?
Did either of you ever manage to solve this? I have the same problem.
I bought a new phone for my girlfriend a s4 and copied the nv items from her new phone to my phone. I had service, changed esn spc and reflashed my phone. Everything is working great now

Great news! Any chance of getting a copy of the NV items so I can try this aswell?

I have to start out by saying that my phone is Sprint Samsung S4(SPH-L720). I’m not sure if this is going to help you. I came here for help. Hoping that I can help out because this site has helped me so much the last four year I have been here. And of course I’m not responsible in anyway for what you do to your device. Just posting what I did to fix my phone. Programs used Win7 64-bit (WIN XP should work), Odin3 v3.07, EFS_Professional_2.0.72, QPST 2.7 Build 422, HxD, DFS CDMA Tool Demo.
My old phone and new phone I bought did not have knox bootloader on them.
First thing I did to both was flash (Oldest Firmware) SPH-L720_MDC_Rooted_Restore.tar.md5 with Odin3 v3.07. Updated both SuperSU and BusyBox from PlayStore on both phones.
Then I used EFS_Professional_2.0.72 to Backup all NV Items from new phone that had cell service. Turned phone off and pulled battery. Then Formatted all NV Items on old phone and restored backup from new phone. Restarted and had cell bars in status bar. So I knew I was good to good with flashing my service back on the device.
Using QPST 2.7 Build 422, HxD, and DFS CDMA Tool Demo verison will work just fine to do what you need to do. Go to Device Manager and find what com port your device is on. Open QPST Configuration click “Add New Port…” the com port will not be visible but if you type “COMXX” in both port and port label it will be added to qpst configuration. Example is my port COM23 so I added COM23. Close window and open DFS connect com and send spc and pwd close DFS. Note: “You have to send SPC then Pwd with DFS before using any programs on QPST.” Open EFS Explorer send spc go to directory nvm\num copy items 0 85 1943 to desktop. Use HxD to zero out items. Then delete items from nvm\num directory on EFS Explorer. Then copy the zeroed out items back to phone. Reset phone and open DFS and restore original setting that came with the phone. You should be able to restore MEID, ESN, SPC, and IMEI with DFS.
I hope XDA Developers will understand that this is just restoring your phone back to original state. That is exactly what I did. Hope this helps you.

Thanks for sharing and i don't think it will work on my device i9505 but i do appreciate the work u have shared thumbs up.
I still think this may work. I want to attempt but I need a known good EFS pro backup from an i9505. Unfortunately it's not that easy to convince any of my friends to let them tinker with their phones. If somebody could send me one to try I would be hugely grateful.

Using an EFS backup on two phones simultaneously will result in blacklisting of both mobile devices.
So do not try to restore an EFS backup from an usable phone..

I did seem MadMediaPro did not encounter this. Also it is unlikely to occur if a SIM is never inserted in the phone. The other possibility is hex editing out the IMEI in the backup.
Mod edit: OP removed
I don't have this problem, but am sure tons of users would surely find this extensive guide useful! Much Appreciated Mate!
Thank you
Very well written, amazing work, thank you for mentioning me too.. For all who lost their imei's, feel free to ask anything about that matter, we have more methods to recover it.
@rombdeta
I think you should post a link to the original thread on htcmania
Thanks
Thanks everybody helped for this tutorial.You are just great
I have done what inside the tutorial,my problem is i have only 3g,so it goes to :
-Have imei but radio off and you can't change 3G to 2G or LTE, it's always in 3G. Put the QCN again, and only click in WRITE NV.
Where to put the qcn again? I presume rf nv manager ,right?
Thanks again ,you are life saver

Yes right, but first do a full backup with QPST, then, yes put my QCN in RF NV Manager, wait you will see "the program can't resset your phone" or something like that, power off your device, and power on. You will see your connections.

I go trough the guide.I have the imei (Samsung Mobile) and 3g but not 2g.Then i write my original imei,i have imei,3g and baseband but no 2g..Then i have full backup of my qcn by qpts.I open Rf NV Manager and put your qcn,then what?Because nothing happens.Pls help.
RF NV Manager
@rombdeta
Could you pls explain to me the steps after put the qcn to RF NV Manager?
When i press put the qcn into rf nv manager , there is no nv items.I chose read supported rf nv items and go to 550 enter my imei,click write nv,write only listed nv items to qcn ,its okay.But once to restore the qcn with qpts there is no imei ,baseband,no signal,nothing.

No need to save the QCN, because that remove some of the QCN package, so you only have to click on "Write NV". Rewrite the QCN package, and do as I tell you, if you can't repair your device, send me a message and I'll help via TeamViewer. Greetings.
Hi @rombdeta, I followed the procedure to restore my IMEI code, but when I click on "settings > comport" the "RF_NV_Manager.exe" crash.. What can I do? Where's the problem?
Try with other PC
I really need help. Gone to CM11 version as specified done the adb shell. Now trying to config a COM Port. I don't know which COM Port is mine? I've got the A001 showing once in other devices with a ? and i have an android device stated as ADB shell in another.
I'm really confused. Please help
Thank god
Figured it out. Might i suggest a re-write?
Very much appreciated though!!

IF YOU HAVE A 32 bits operating system, you will see two A0001 in devices manager

@rombdeta sorry if I annoy you, but I want to ask why I do not have "images 1 to 10", and how I know what COM port is my device? (In "ports (COM and LPT)" in device manager I've only "communication port (COM1)" and "printer port (LPT1)")

Now I have my IMEI and my SIM just works fine. But I have a problem, to connect to a mobile networks the phone takes more than one minute, and I have to search the networks by myself.
EDIT: I noticed that 3G works (connected in 40/50 seconds, I think it's a bit slow) but the phone can't connect to 2G, with LTE didn't tried becouse at home I don't have it.
Received an invalid command from the phone.
what can i do after i press start it gives me this error " Received an invalid command from the phone.
"
This guide is for those who have lost their IMEI, have corrupted EFS, or erased EFS partition. So, follow these under your own risk, it may or may not work, and if something happens or doesn't happen, then i am not to blame. So, once again i will not take credit for bricked phones or something along those lines, however i will take full credit if this works for you. I will also provide assistance to those who could not restore their EFS following this guide.
Before proceeding with this guide, backup what you have left. Use twrp to backup and in case something goes wrong and your problem escalates, you can restore using twrp backup.
Restore EFS
Change IMEI Number
Restore EFS
Do this if and only if you believe your EFS is corrupted, or you somehow erased it. If you are not sure about it, then simply follow the next guide to change you IMEI number. In most cases people loose their IMEI only and not the whole partition. Again, it may or may not work, so do this on your risk, and i am not to blame if anything bad happens, but if you do succeed, then don't forget to give me credit.
Note:
If your EFS is erased or corrupted, your IMEI and Baseband will be shown as unknown. In this case recover the EFS following this post, and then change the IMEI following the next post. If your IMEI is shown as 0, then you EFS is safe and most probably your IMEI is gone. In that case, no need to recover EFS, only change the IMEI number following my next post.
In TWRP, backup of kate wont show on kenzo and the backup up kenzo wont show on kate. In case no backup is shown even if you are using the right device, then try the dump flashing method or try changing the TWRP recovery.
Flashing this will only restore your EFS partition, but the IMEI will still be gone, so you will have to follow the next guide to change your IMEI.
Even after flashing a new EFS, you Mac and BT address will not recovery. The android system will assign a software generated address to both devices. Dont worry cause even without the EFS partition there will be a Mac and BT address assigned to your device and both the things will work normally.
If your Baseband is still unknown, even after flashing a new EFS, then try flashing latest radio file. It can be found in any firmware update package, either the official or the one from the strix.
1. Download the required files from the link given below.
EFS Backup[Kenzo] - Contact me if someone has backup of this.
EFS Backup[Kate] - Contact me if someone has backup of this.
2. Extract the Dump Backup files and flash them using the following commands.
Code:
fastboot flash modemst1 modemst1
fastboot flash modemst2 modemst2
3. Now reboot and voila you have you a new EFS partition at your disposal.
Change IMEI Number
Requirements:
Root
USB Debugging is turn on
Windows Driver Signature is turned off
ADB and Fastboot Binary Files
Latest MiFlash Installed for the latest drivers
1. Connect your device to pc and open the adb folder. Then open a command promt window.
Code:
>> [B]Shift + Right Click[/B] anywhere in the adb folder
>> Click on [B]Open Command Window Here[/B]
2. Type the following command to enable Diagnostics mode. Allow debugging if asked.
Code:
adb shell
su
setprop sys.usb.config diag,adb
4. Download the IMEI Changer from the link given below.
IMEI Changer [Credit: Archeolot]
5. Now, open the imei changer, and enter imei number in both the fields. And click on start. After a moment it will show as passed. If it fails make sure that you have followed the points i stated.
Note: Make sure that the driver in driver management under ports is listed as "Qualcom HS-USB Android DIAG 901D" and not as "Marshall London HS-USB Android DIAG 901D". If it is listed in any other name, then go to driver management and update driver. Select browse driver, then let me pick driver from a list. Then select "Qualcom HS-USB Android DIAG 901D" and then finish.
WOW.. Thanks mate..

Can't confirm. My EFS partition was so corrupted from trying other tutorials to restore my IMEI that I didn't even bother backing it up because I thought that it could have been changed already (tried writing to NVRAM with QPST). Since I don't have my original mac and bluetooth addresses written down anywhere (I haven't written them down myself and I don't think they are to be found anywhere on the box or on the phone) I think the only way to check it would be to compare my current addresses on the phone to the addresses contained in your EFS backup. Can you extract them so I can check if they match or not?

The mac address and bluetooth address in the efs are my own. I only changed the imei so that no one else can copy it, i didnt know anyway to change mac address. Besides the mac address doesnt matter that much, and i dont think that we will ever be on the same wifi network.
If you dont know then i can explain, that the mac address is required to maintain switches and broadcast in the router, so it technically does not matter.
You can change it later with some apps or use it like that if you wish, if i find any way to restore you mac i will post it too. In the mean time just post a snapshot of wifi mac and bluetooth address so that i can compare them with my own.
So, using this way, one can change the IMEI no. also?

Yes, just use the imei changer in the rar file to change your imei. But make sure to backup or atleast note down your imei before doing so.

Yup, they are not mine. Mine start with 64:cc and so on for both mac and bluetooth. They may be software generated or may be your own, technically i am not sure.
Edit: did you use imei changer to change imei no. Or are you using the default values. If you are using the default values, pls post them too. If you change them, then give your review, ie was it hard or easy, did you encointer any problem, stuff like that.

After flashing your EFS backup both IMEI values were set to "0". On the default values I don't think the phone would be able to register on any network with the sim inside, but I haven't tried that. Then I flashed my IMEI with the app you provided in the .rar. Set my IMEI same for both slots because I've got only one written down on the box so I think it is set how it should be out of the box. After that I've rebooted to EDL and flashed global developer rom. And it's all working, I'm able to make calls from both sim slots, however didn't try having 2 sims inside.
All in all the process is very easy, definitely the easiest out there. I haven't encountered any problems, however I think others may have a problem with drivers to get "Qualcom HS-USB Android DIAG 901D" working. Mine was working already because I tried this tutorial before. Thank you for this guide, and providing your backup

Guys. I messed up my phone by restoring a nandroid backup from a different one.
I was able to restore my IMEI using some qualcomm tools. My problem now is that fingerprint scanner won't work on any rom, even official.
Any idea what else I have messed Up? I don't think restoring this efs will fix my fingerprint scanner. Is fingerprint scanner info in a different partition?

Have you checked with miui7 stock rom. As far as i know there are three sensor modules for fingerprint, on of them is goodfix which is currently not supported by many roms. If your is goodfix then it will not be supported too. You can flash miui rom to check whether the fingerprint works or not...
If it doesnot work, then try to resotre your nandroid backup agaian. This tym simply untick efs.
can someone point me towards a persist.img, or make a backup on their own Moto G4 Plus and sent it to me please.
i've backed up mine, but it seems to be corrupted and prevents me from using the cellular part of the phone.
thanks !
Little bump on this thread
After some more reading i figured that i appearantly whiped my EFS (NV) items from my phone by moving the persist directory. Came accros a few post specifying Qualcomm's QPST software in order to restore the EFS items. I've booted the phone in diag mode and can make a backup up my EFS (NV) items using the Backup option in QPST Software Download.
But since my IMEI is now 0 (on both SIM slots) i can't seem to find the position of the IMEI number in a HEX editor.
I'm following this tutuorial which seems (in my opinion) the most viable one for succes.
So what i need is a QCN backup of a working Motorola G4 Plus with the IMEI numbers replaced. (say 0X1A1111111111 and 0X2A222222222)
Hi, i am sure noone would like to share his NV-Backup to any other user. This IMEI is uniqe like a MAC-Address. Never saw a replacement of an IMEI in this way. You can try to download an app, which gives you a fake IMEI, use IMEI Analyser (for ex. https://www.youtube.com/watch?v=UZzZ0yhkxX0). I also tried this on my MOTO G and it works perfectly. Root is needed.

I've got both my IMEI numbers (which i grabbed from the sticker behind the back cover)
Problem is, i don't know where to insert them in Qualcomms QCN file since (according to tutorials) i have to search for 08xA (where x is the first number of my IMEI). Which in my case is reset to 0. Searching for 080A doesn't yield any results

Hi, i am sure noone would like to share his NV-Backup to any other user. This IMEI is uniqe like a MAC-Address. Never saw a replacement of an IMEI in this way. You can try to download an app, which gives you a fake IMEI, use IMEI Analyser (for ex. https://www.youtube.com/watch?v=UZzZ0yhkxX0). I also tried this on my MOTO G and it works perfectly. Root is needed.

Tried several of those apps, don't seem to work on my phone (which is rooted) Als tried some IMEI rewrite apps offered by the Xposed framework. No dice.
NV-Backup would be best, i just need to figure out where to insert my own IMEI in that file. So if someone could remove both of their IMEI's from the NV-Backup and replace them with (lets say) 08 11 11 11 11 11 11 11 and 08 22 22 22 22 22 22 that would be great.
@populus_ maybe this could help you: [Guide] [XT16XX] [Solve] Moto G4/Plus IMEI=0 issue
Thanks for the heads up. But unfortunately i don't have the persist partition any more. Only solution i could find is that i hook my G4 Plus up to a UMT Box (IMEI repair)

The tutorial which I mentioned doesnt need persist partition. You should be on your own persist and not of someone elses, thats the criteria.
You can recover your both IMEIs like I was able to do and many other Moto G4 Plus users too.
I have recently bought an Essential Phone from ebay with broken radios. No imei, no wifi... After troubleshooting, I found out that the QCN file was completely wiped. I have the original imei written on the phone and paper but need the copy of QCN to restore it. Could somebody please help ?

It's not safe to share imeis. Could you just edit yours with dummy imei and pass me the file? I can hex edit my original imei into it myself.

You are right. Actually, I dont have much to lose anyways as the phone is becoming replacement parts if I can't repair it. I will sent the imei via pm. Also, not sure if qcn restore if even enough, there is a chance of broken efs as well.

Qnc fixes efs....if it doesn't you could send me your nvrf partition,I could inject your IMEI into the one I pulled from mind and send you the fixed one...
Hi
Hello everyone I am so sad. Because A few days ago I noticed that the baseband was unknown. IMEI 1 and 2 unknown and Android ID Null from my Asus rog phone 2 Zs660kl version I001DC Global version and I cannot do anything because there is no any Qcn file for this phone , I am unable to do anything in my own, I do not live in United states, I cannot send it to repair, it would cost me the tax again, like 147 dollars again that I paid for the customs. Please if anyone has a good hearth to back up the Asus rog phone 2 file from the same version with the qpst toll... I would really appreciate. I need it , I tried to find the IMEI with Hxd editor and there is not any 1111 to find the error so I am unable to to that. There is no any Qcn file. I need a Qcn file from the same phone with a phone that has the baseband and the rest fine".
I need to have the Qcn file from this same phone I have issues with the baseband IMEI unknown and Android id Null, by doing this you can help through diag mode you just follow this just download Adb minimal, open it and and write Adb devices, then Adb shell then Su and finally setprop sys.usb.config rndis,diag,Adb enter and in device manager you will see in ports, Qualcomm devices which you can continue doing the next step which is installing latest drivers from Qualcomm on this video you can follow the steps After installing the latest qualcomm driver, the qpst tool will recognize your phone because it is now on diag mode since you did the previous step, by checking this video you can back up the Qcn file which is what many people need and there is no other way to solve the issue only with a phone which is in perfect condition as yours
how to use the qpst tool to backup the Qcn file , First diag mode with the commands I gave you second is installing the latest qualcomm drivers then backup and restore Qcn , and then you will have it done,
download the qpst tool and the Qualcomm drivers and it is an example of my problem with the baseband, you can guide with the one video and the third , the one video do not use the commands given by the YouTuber, because that do not works, use the commands I gave you , that works for our phones, and then the third video is explaining how to backup the Qcn file which contains the data? I was unable to edit myself the Qcn data from my damaged phone cause the IMEI is not there, there is no any 11111 number to replace it for my own IMEI, sadly,... Just need the Qcn from a good phone, please!!l
If anybody is still offering to do this and can help me... My phone is hard bricked and I can't do anything... I feel I can fix it with a QCN... Anyone want to help?
