Good evening to the entire XDA community . I'm new to this forum, and I need some help if it is possible, apologize if you see something strange but this is the only forum I know where everyone is active, about android, hacking, roms, etc. Here is the question:
How can I change / modify the IMEI of my Nexus 6P Huawei?
I have reviewed several topics here on how to do it, I have done a process to roote this phone because it does not allow it from apk but by flash, so I have rooted it, installed XDA ROM (Flash) and XDA Framework application, also the well known TWRP Which is the recovery mode I am currently using.
I Tryied installing a module called Phone ID changer, but it did not work with several attempts, so I see only hidden the IMEI but does not change it, so my phone is still without mobile network service because of the report.
I decided to investigate a folder called EFS that supposedly contains all the information about the IMEI and where it can be changed, I tried with the Root Explorer application and try to find it but I could not find the EFS folder even with the option to show hidden files. BUT by entering recovery mode with TWRP and entering backup, it allows me to make a backup of that folder (EFS) so the folder is on the phone, but I do not know exactly where.
This is all I have tried so far to change my IMEI reported to be able to use my phone with SIM and signal. Please help, this is the only forum I see active mainly in android, I have searched thousands of videos, tutorials, etc but I have not been able to find something that changes the IMEI to a new one.
Thank you very much to all.
Data:
Phone: Nexus 6P Huawei
Android Ver. : 7.1.2
Recovery Mode: TWRP
Problem: Can't change IMEI
If you need more information, please comment it I will gladly add it.

Questions regarding change in IMEI number of android not allowed on xda. It is illegal and you don't get any help regarding this. So better you don't ask here or find it yourself.

Hi All,
I’ve just got myself a “bargain” from eBay that was advertised as unlocked but alas turned up with the sim lock on
I’ve contacted the Tmobile network in the UK and they will only send a code to a uk address and I am not there.
I have looked on this and other forums and seen that I could do it myself. I have rooted the phone and now have the yellow warning triangle on boot up. I also have CWM and Superuser icons in the Applications.
I have then tried to go onto the android app store to download Chainfires Galaxy S2 SIM Unlock. I then get the "There are no Android phones associated with this account" problem. Again I have looked at the solution to remove the phone number and re-enter it but this has not worked. I have tried several times.
I do not have Wifi and obviously can’t access the internet on the phone.
Is someone able to kindly send me the file in an email?
Once I have this done what else do I need to do to the phone? I’ve rooted it but only to the closest number I could find.
Thanks to XDA and all of you for reading this!
I'm a little slow so plese can you dumb it down... alot! ha ha
Phone: GT-I9100
Android version - 2.3.5
Baseband version - I9100BOKJ1
Kernel version - 2.6.35.7-I9100XWKE2-CL187606 [email protected] #2
Build number - GINGERBREAD.BOKK1
apk
That app only works on early version phones and may not work for you. If it doesn't you should try Helroz's Galaxy S Unlock app it works on all S II's but I believe it requires Internet to get a small payload. Which could be a problem for you unless you drive around for the first open WiFi.
It also doesn't give a code it just straight unlocks the phone.
Thanks. I have downloaded this to my computer. What do I now do with it?
I'm still lost... What do I do?
Please can anyone point me in the right direction!
Thanks
Place the app on your internal or external sdcard and install. Ensure you have enabled 'unknown sources' or something like it in the phone settings first. Allow it root access when prompted by the super user app.

Thanks for the quick reply,
The phone is brand new to me and I don't understand your instruction. I have downloaded the file and extraced the folders and files. I have then placed this onto the card. I then go into the phone and have ticked the unknown sources box. I then try to run any of the files and only get a "No applications can perform this action" error.
If I try to run AndroidManifest.xml it opens HTML viewer.
Anyone Please....
It's an apk, you weren't supposed to extract it. Apk files are android installation packages. Push the apk to your phone's sd card, and open it using the "my files" app to install.
Thanks again. I've done that. I can find the file eu.chainfire.sgs2simunlockcode.zip in My files. When I tap on it I get the message "Open file. No applications can perform this action"
What am I doin wrong? Thanks for your patience

You apparently somehow changed the file extension from .apk to .zip. Change it back.
I had to change the file extension from .zip!
I am not running the app and hopefully that will work. Wish me luck!
What else should I do to a new phone? Is there any way to get rid of the Tmobile startup screens?
Thanks for all your help, you have helped me stop pulling all my hair out and shouting at the dog!
The app did not find an unlock code
Anymore ideas anyone?

You can flash a stock unbranded firmware... But it sounds as if you should read a lot more educational material before attempting this. Lots of good information is in the roll up sticky in the i9100 general section. Start there, and start reading. I can't offer you any shortcuts. Shortcuts tend to lead to frustration and bricked phones.
I have looked into other ways to unlock this phone...

Aren't there services on the web that cost abot $40 and send you an unlock code? I understand that you don't have wifi, and the phone doesn't work. But if that's the case, how r u posting here?

I have a computer with a sim card in it. I know that there are services to unlock but I am trying to avoid that cost if I can. Perhaps after I have tried all other options I will have to go that route.

Hi,
I have made a mistake trying to change a rom for my device (Lenovo s820).
I thought my phone was gone, but step by step I was able to bring it back to life.
Now I have a working rom and I set back the IMEI's, but I still have "no service".
After reading a lot, I understand that I need to recover my "NVRAM" and to do so, I need for somebody to send my a file called "NVRAM.IMG" which applies to my device.
I can't find this file anywhere on the net.
Can somebody please send me?
Thanks in advance

Attempting to change my MAC address I deleted 4 files whose name where WIFI.... something. Right after that My wifi went down and the phone is no longer WIFI capable. I know that I was surfing ROOT file system but instead of copying I clicked delete.
Yeahhhhhh My phone is a chinese model running 4.2.2
what i did was using Xroot file searched for WIFI and selected those files to delete.
SO my guess is that I deleted not only my MAC address but also other configuration files.

You know how many Chinese phones have 4.2.2? Me neither, because there are so many (100s), with such poor documentation that it's ridiculous. Without knowing more info about yours such as board type, brand, screen size, etc, no one can help you unless they have some sort clairvoyant powers.

It would have everything to do with the model of the device. If you have deleted essential /system files, then without knowing what OS and phone you have, how could we get you the right files to replace? It even matters on many of these devices how much storage you have as well because there are different tools to reload depending on that. Seems like it shares a lot of stuff with the Star S7589 phone, so might find stuff on that one to fix if all else fails.
Thank you!
Well what I did was to search WIFI on the root folder... (I wanted to change MAC address somehow) but instead of copying the files for further analysis I deleted like 4 results that apeared with the word WIFI... I am not sure where did I deleted them from...

Send me the updater-script in the ROM there might be some problem with that..
Sent from my XT1033 using XDA Premium 4 mobile app
Well I've no clue what you were trying to link to because no matter which way I searched for it, nothing would come up that was close. Tried on the PC and phone and made sure to put the address in how needrom.com would typically see it (I'm familiar with the site) as well as searching for just bits and pieces of the link in Google and on the site. But if it is the original rom for an Alps phone, most likely you have to load with SP Flash Tool, not recovery.
I found this one, which is the update before the one you posted, I think, but it has the how to on flashing: http://www.needrom.com/mobile/star-s7589-10/ Even if that isn't the right firmware, it should be the correct guide to installation.
Thank you!

There is no file like that inside the zip folder
....
Just be sure to load the correct stock ROM and you should be fine.
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
I would suggest to install Xposed and you can find IMEI changer in the download section. This will change only one IMEI number though. I mean IMEI1=IMEI2.
Another option is to use DFS tools.
And a 3rd option is to use Xiaomi (or similar for dual SIM) IMEI changer, you can use it to change both IMEI numbers.
All can be done provided that you have the box that the phone was packed in with the IMEI numbers on it.

Go to the section Guides where you have posted in a topic with "unlock bands..." There you have all what you need in the OP. Connect your phone in DFS tool, check the section where you have IMEI and update it.
Or use what I wrote with Xposed and IMEI changer.

Search for "WriteDualIMEI(W+G_eMMC).exe" file. Once you found it, check instructions on google to change the IMEI. It is working for Xiaomi devices as far as I remember. I tried on LeMax2 and it worked. I said I'll do a guide but time did not allow and also I forgot later on. For sure you can find instructions on xda as well.
This is the only tool I found to change both IMEIs.
Good luck!

I'll write down the instructions for you.
1. Phone should be rooted, adb drivers installed
2. Connect the phone to PC and select MTP and USB debugging
3. Open command prompt from Start. In Run, type cmd.exe
4. Type in the command prompt the following: adb shell
5. Then it should show [email protected]_x2:
6. Then type: su
7. Grant access on the phone
8. Then it should show [email protected]_x2:/ #
9. Type: setprop sys.usb.config diag,adb
10. The phone will go to Diag mode, check in device manager if it's like this. It should show at section Ports: Qualcomm HS-USB Android DIAG 901D (COM6). "6" is an example.
11. Open the WriteDualIMEI app and you should see in COM: COM6. This means that device is connected and you can type in the IMEIs.
12. Press START and that's it.
Ok. So here's the deal:
My SGS3 I9300 exynos phone did the famous IMEI 0049 and SN null trick.
I cannot say what precipitated it but is simply stopped registering on the network, so no calling or data. All other functions operational.
After much searching and reading, I settled on flashing the stock 4.3 back. This succeeded only in doing absolutely nothing to alleviate this issue. I wiped the entire phone. Maybe I missed a critical section wipe, but since the stock ROM overwrites all? the CSC/BL/MODEM functions I thought it would set the default for EFS (which I believe is where these critical data live). I'm not a programmer so I cannot say diddly about the architecture and interrelationship of OS files, but I am technical and I know how SW and HW does what it does.
This phone is my own and I have all the rights to it.
I had loaded RRemix ROM a loong while ago and it was functioning fine. Probably a corruption of the EFS due to battery contact being loose. This is in my mind the most likely cause as the system may be accessing the EFS files, say making a call, or accessing data, and the power drops out and voila! Corruption. But again this is theoretical.
Needless to say I tried the usual hocus-pocus out there with no avail.
Getting to understand the system better it seems obvious that these critical identification numbers are hard-coded into the chips on the phone. Which explains the ability to 'fix' them with JTAG and other cable/box solutions and SW. However, I cannot see how the SW loses the ability to read the IMEI/SN that is hard-coded (fused?) into the main-board.
All my research pointed to the EFS files having something to do with this.
Way back when I loaded the custom ROM I did not come across the 'backup your EFS' as a necessary step, so I had nothing to go back on.
And loading the stock 4.3 ROM back on and not having that fix the issue, led me to believe something else was up.
Somewhere in the guts of this phone something is screwing up the layer between reading the registers where the numbers sit and the software layer that reports the numbers.
So, much searching led to the nv_data.bin file being a key component in all this fiasco.
Now, before I say any more, I believe that describing the next steps could be a big no-no here.
Now, understand, all I want to do is get MY personal device working again. I have the SN and IMEI numbers on the physical device.
Sure, I could have stolen it and am attempting to change these to avoid prosecution. Anyone can say anything online.
Therefore, before I can proceed, I need advice from moderators and VPP to either say 'Yes you may post this info' or 'No. Go away'.
Am I allowed to do the following:
1) Describe how I restored my IMEI (Not changed, overwritten, or subverted to my limited knowledge)
2) In the case of 1 not allowed, post the link to where I found the info to achieve this.
3) Submit the 'fix' to a moderator or developer to check whether this is indeed and restoration or a change.
If it's a restoration of existing functionality, I cannot see how this could be a problem. If its changing something, then it's a whole other sack of ferrets.
My reasons for posting are that xdadevelopers has given me years of joy with my SG devices. (Yes, I have the whole range exclusively) Many ROMS, customs, fixes, hints and saves deserves something back, and the difficulty in achieving this particular fix, warrants it.
But I don't want to break any rules, this being my first post.
So, please let me know what I can do to help others stuck in this position...
You can find it if you have the correct search parameters. Perhaps I can say that instead?
Thanks.
And thanks to all who have helped over the years.

[Edit] Just to clarify, the solution requires no special HW or 'boxes'. You do need root, however, and a hex editor. I had a reply explaining the use of Octoplus, which requires credits and registration. You will need none of those.
I can't speak English but I will try.
1- flash stock firmware.
2- root your device s3 .
3-in the web download " octuplus crack box"
4-in youtube see how install " octuplus crack"
5- before install stop your antivirus PC
6- open octuplus and connecte your phone with PC
7- chose your device i9300 .
8 click repair imie
9 click read info and do what OCTU said to do.
10- click repair or write the true imie in your device ( remove battery to see)and click repair.
11- restart phone .
12- see: call work fine
13- in phone go to mobile network\ access point names\ apn's

How to restore corrupted or null 0049 IMEI on SGS3.
Right.
Thanks to the moderators for agreeing to let me share the solution. :good:
Thanks to the reddit poster who found this solution. I don't know how the hell you figured this out, but big-ups to you. For privacy I will not mention names or addresses.
You do need a rooted phone and I cannot assist anyone without root as I have not tried it.
Whether this only works to restore a corrupt IMEI or change it, I cannot say, but it managed to restore my existing one.
Preparation: Get your IMEI number from under your battery compartment. Say your IMEI no. is: 123456789101213, write/type it in the following fashion: 1 23 45 67 89 10 12 13
Now some funky transposition: Excluding the first number, transpose the subsequent pairs of numbers so that you have: 1 32 54 76 98 01 21 31. Can you see it? Swap 23 to get 32. 45 to get 54 and so on.
Now add 08 to the beginning and add A after the 1 so that the completed number is: 08 1A 32 54 76 98 01 21 31
Now you will need:
Rooted Galaxy S3 (This may work for all android devices that have an EFS folder. If anyone can confirm that would help others.)
Hex editor (PC based or Android app) - PC is faster and easier. I used hex workshop trial version but I'm sure any editor will do. I used the default install configuration.
USB Data cable (if using PC editor mentioned above)
You should probably back up the EFS folder entirely, just to be sure.
Using your favorite root explorer browse to root/EFS folder and copy the nv_data.bin file to an accessible area in sdcard. I use a /sdcard/Downloads folder.
Either open the file with your hex editor app or transfer the file to PC where you can open it with your hex editor program.
Open the file and jump to address 00550.
Now, get your modified IMEI number from the prep steps above and enter the values in the ASCII TEXT window to the right, NOT the HEX values window to the left. This may be different for other editors but hex workshop works like this.
Double check your address and entered data. When satisfied, save the file and transfer back to the phone if copied to PC.
Now, place the phone in Airplane mode, turning off the cell radios.
Go to the EFS folder and rename the original nv_data.bin file to something else. I used nv_databak.bin.
Copy the modified nv-data file into the EFS folder.
Turn off Airplane mode and do a full reboot.
Your IMEI number should be restored and cellular functions should work.
My previously garbled serial number was also restored.
I hope this works for you. I have no knowledge of any other method as I did not delve further into trying other numbers or such. I can't assist any more other than further clarifying the steps above if you don't understand something.
If anyone can decipher what is going on here, I would love to hear about it. I suspect something between the HW and SW layers is getting garbled or corrupted and this kick starts the process to get the correct data again.
Maybe.
May also contain nuts.
Hastalavista.

THANKS FOR POSTING THIS HERE!
I have this Samsung Galaxy S3 that I bricked 4 years ago and never wanted to sell it or even try to give it away. I searched for months for a frekin solution to this problem. Yesterday night i decided i wanted to try and install custom roms on it and so i wanted to give another shot at this stupid issue i had with the lost IMEI before doing so...and BAM! Today it's fixed!
I'm so thankfull I wanted to post here so that you know that you helped at least one person with this
Thanks a bunch!
@TrinityTrip54
Hi,
can you confirm that this is a permantent solution and remains when flashing new (custom) ROMs? Or is it just for the current installed ROM?
And I am having an issue with "jump to address 00550" in Hex Workshop. There is no address like this, just 540 and the next one is already 558. When inserting 00550 in the goto search field of Hex Workshop it jumps to 210. Any idea?
thanks anyway.
