Hey guys,
I'll put it as simple as I can :
-no SIM service whatsoever. Happened a few hours after i flashed Androidmeda ROM. no clue if thats the reason
I tried:
- restart
- wiping all caches and data
- factory reset ( 3 different ways )
- flashed 3 other ROM's
- recovered a very old nandroid backup i found
- drained the battery, recharged fully
- left battery out for a few hours
- slapped it around (gently)
Im drained out of ideas. Any clues? anyone?
Thanks in advance
Sim card in slot .
Check you have the correct network settings .
Check IMEI is the original one .
Wrong IMEI restore your backed up EFS folder .

Just one Q.

is rule one backup efs folder so you can restore your IMEI ..
The /efs folderThe /efs folder is a folder in your phone that contains information specific to YOUR phone, for example your IMEI number, product number, Wireless MAC addresses, and much more. There have been reports of people messing up their /efs folder when unlocking their phone or flashing new ROMs, here is an example from the Nexus S development forum (jump to page 111 to see everyone start to panic):
http://forum.xda-developers.com/show....php?t=1034130
Therefore, it is important to make a backup! Instead of just regurgitating guides on the forums already, here is a link to a very good one by Rawat:
http://forum.xda-developers.com/show....php?t=1068193 (Rawat)
The easiest way of doing it is by using terminal emulator rather then ADB (unless you have ADB all up and running and are confident with it)
You need to search the other multitude of IMEI posts see if you can find a fix .
If not its a service centre repair if you have proof of ownership and no custom rom and no root and custom rom counter set to zero .

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..
It's gonna very Helpful for me & other ppl.. ??

Glad i could help mate. Can you confirm your mac address and bluetooth address, whether it is same or changed.

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.

Current addresses on my phone:
MAC - 00:0a:f5:a9:XX:XX
Bluetooth - 7C:7F:F0:82:XX:XX
Left out some numbers just in case they are mine. For the purpose of checking that will still be enough

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.
before i asked many people for fix but no correct solution is got but ( thanks for devs support). now i experimented and solved imei and efs partition currupted by qcn method
NOTE: ( third party qualcomm imei changing softwares will not work i tried many but no use)
steps
1. first download tools and install
2. go to qpst.exe in c:/programfiles/qualcomm/bin/qpst
3. now connect your phone open port by dialing(*#*#76937#*#) in stock
4. check whether qualcomm diagnostic port is enabled or not in device manager
5. if it shown enabled and device info its connected through diag port in qpst
6. now click software download and take backup of ur partition and save as (.qcn) and click on start it will read ur partition and
xx.qcn file will created(xx is any name)
7. now open hex editor search your imei number with [08xa] x is your starting digit of imei example(087a) for second imei click
find next option
8. now open your imei convertor and palce your imei and click convert
9. replace that converted imei in the form of hexadcimal replace with old imei same for second imei
10. important thing is while saving the file only by (save as) which is important if any mistake is happen we cant recover after
restoring in efs partition.
11. after saving again go to qpst npw go to restore option now click on start .
thats it! you got imei and signal:laugh::laugh::laugh:
i struggled 3 days for this to find correct way recover my ime
tools here
From what I understand I guess you lost your phone.
You should have your EFS partition backup as it probably contains all the IMEI information from your phone. I can't imagine an EFS partition from other phone working into yours without duplicating an existing IMEI.

Did you backup the EFS partition before starting changing ROMs over and over?
If yes, try restoring it.
If not, nothing to do.

yes i fixed even without backup of efs already , also posted fix in guide forum
I don´t have the option
I have a Lecco Le x626 but when I write the code #*#76937#*# only appear one option "Sleep Sing On" no more what do I do for activate to option necessary for that thanks
maybe a stupid question, but if I do a full backup including nandroid via TWRP before flashing anything, will the imeis be included? thanks

Only if you check EFS partition to be made a backup, otherwise IMEI will not backup.

Sadly, the x626 (a.k.a Le S3) is a MediaTek Device, so no Qualcom Mode available.
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

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.

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.

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.

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?
