Hi all,
Managed to screw up my phone during a flash operation resulting in losing/corrupting my EFS partition and my IMEI number in the process. Being looking over all the Internet and I was able to find the procedure to follow to restore it but a need for a kind soul to send their QCN file to me, after previously of course changing their IMEI number to a dummy one.
For the ones not familiar to this but willing to help, please take a look at http://techsarjan.com/2016/10/fix-invalid-imei-problem-xiaomi-mobiles-miui-8.html for the restore IMEI one. Taking a backup of one is just going to the "Backup" tab of the QPST tool and the rest is obvious.
Thanks in advance.

I will make a backup tomorrowand will send you. Don't worry
Thank you for your reply via pm.
I would also would like to add that if you have problems in restoring the qcn file in the qpst tool, from the type of unable to open file, it's probably due to the fact that you're using the wrong file editor tool to change the imei. I was using ultraedit and it was screwing my file. Switched to hex editor and it solved the problem.
@dragonii @SAFI_AFRIDI It would be nice if you could post that file in here. I mean censored file in here. So future users will not have to beg for it.
In the meantime, I received from another source all the needed files (in Russian only) but with Google Translate, it should be ok for anyone to follow.
The QCN file, based on the filename, is for Redmi 4 Pro but I can confirm it worked also for the Prime model.

[Guide] Fix Invalid IMEI
How did you repair the efs partition? I got my imei restored on my note 4x but haven't been able to fix the other parts that have gone wrong.

Hello, I need help, my gtab has blocked the imei, it is possible to change the imei?
Thanks!!!
I think theres an nv_data file in the efs partition that can be edited with a hex editor, but its quite risky, so make sure you research and google everything a lot first. If you've got a backup from superoneclick or something like that, its sometimes possible to restore your imei from that md5's and bin's in the efs partition.
Would someone please PM me a link to a copy of the nv_data.bin file, I need them for some new research.
Thanks in advance.

Hi Odia,
I can provide you with an nv_data.bin file or even the content of the whole EFS folder. I also have a question on this - I heard and see that you are The Expert here on these kind of stuff. The stuff I can send you does not contain my EMEI only a generic but otherwise seems to be OK. Let me know how would you like to receive the files. Also I have to state that - although it would of course be welcome - your help is not "in exchange" for mine.
So here's what happened:
1.) I was using various custom ROMs (rooted of course)
2.) Went back to leaked stock ROM (here comes the problem) 4.0.4 LPQ5. Unfortunately I learnt only after installing the ROM that its PIT file is corrupted. Error messages begun to show about "internal storage not formatted", etc. probably here I made the second mistake agreeing to format the storage. After that I had generic IMEI, had CSC, HW_rev. and Unique number unknown and a black semi transparent window stuck to every screen showing that.
3.) Re-flashed (with Odin) an older Samsung stock 4.0.3 FW (actually the one I bought my phone with), now everything seems to be solved except the IMEI which is still generic 004999010640000. At this stage I took a backup of my whole EFS folder I can provide you with. (Yes I know, I should have taken a backup of EFS before I started to even touch the ROM)
I learnt that the nv_data.bin contains the IMEI in an encrypted form so restoring the original IMEI it's not a simple hex editing. And that's where I'm stuck at now and would welcome any help.
Best regards and please have my appreciation on your work and contribution here!

You can`t share a EFS ( http://allandrophoness.blogspot.nl/2013/05/android-to-z-what-is-efs-folder.html) folder, it is specific for one device containing much data . You need to install a new motherboard if you lost your EFS folder and didnt`t make a backup that you can restore.

I know that , but i need a generic one from another device for adapt it on it building a new one, please if somebody can share it.
This forum doesn't condone anything to do with IMEI or EFS manipulation or practices that could aid repairing stolen handsets.You've been a member for more than a year, so you should know this. Or would if you spent five minutes pursuing existing EFS threads here.
If you had done a Google search you'd already have answers. This is the wrong forum to be asking such questions.

No, you cant repair your stolen S5 lol, call to mobile operator and go to Technical Service
imei is invaild in lenovo A328

or any other way to fix this

BR,
Step by Step Answer
Ok so I'm sleepless after an all night session from having the same issue with my partners a369i, many fruitless attempts to fix it until I did the research into why this happened so here's a basic tutorial and the final fix which works for all lenovo's...
Custom roms on lenovos wipeout the 'NVRAM' where the imei is stored resulting in 'Sim not detected'.
You will find 3 main ways to change the imei but they will all fail if you deleted the NVRAM (took me 7 hours to work this out for myself!). Roms generally don't contain the NVRAM files because then every device using the same roms would have a duplicate IMEI, It could take some searching online to find the nvram backups (ian if you still have the issue i am expecting delivery of an a328 later today and can send the files if you PM me.)
ANYONE READING THIS BEFORE FLASHING TO A CUSTOM ROM USE THE STEPS BELOW TO FIRST BACKUP YOUR NVRAM (backup is directly above the restore function). I strongly recommend doing all the following with no sims installed, I rebooted with sims after flashing NVRAM but before changing the imei and i was given a harsh onscreen warning by my network operator that i was using an invalid imei.
Use this only to fix a broken imei with your phones original legal imei's, please do not use for fraudulent purposes to clone or fake an imei
search online or ask a friend with the same model of Lenovo to backup their NVRAM (you will have a duplicate of their imei which can be changed in the final step), you will have a bin file and a tar file hopefully.
I recommend reflashing your device to ensure you are starting fresh.
Download and install 'SuperSU' for root access, no root no fix!
Download to your PC MTKDROID Tools
Connect your device via usb in debugging mode it should be detected by mtkdroid tools in <30 seconds.
Click the 'ROOT' button in mtkdroid to get full root and this allows the application to have terminal access to the device.
when the indicator box is green (ie not blue or yellow) now click the NVRAM / Imei button to open the next screen.
Extract your downloaded backup NVRAM files to your desktop, in the mtkdroid nvram screen go to restore and browse for your backup files. It will flash almost instantly with nothing else to click, you now have created the folder structure and correct files to allow an emei change, you don't need to reboot your phone at this step but if you like you can do so and see that you have gone from a null emie to the one in the backup files.
You can now use the 2 text boxes in mtkdroid tools to enter your own valid imei, click 'CHANGE'.
The process is now complete you can reboot the phone to detect the new emei, i recommend doing this without sims installed for the first boot, once verified in android you can install the sims and use as normal.
issue for fixing imei
Hi guys,
above methods are not working for my lenovo a328. Please help us guys.
Root your phone.
Install ROOT EXPLORER.
Navigate to DATA folder, locate NVRAM folder and delete all of its content!
First set permission to data folder to RW or else it won't let you delete any files...
Reboot your phone.
Now A328 should generate the correct IMEI.
Good luck!
If anyone needs a NVRAM, this Russian forum thread has all of them. but it requires registration.

Hi Guys,
Recently I lost my imei. I don't know what happened but I tried everything nothing helps me. There is only one hope. I need someone qcn backup file. if I get a qcn file I can restore it to my phone and I will change the imei number by using EFS Proffesional Tools.
You can change the imei number of qcn file using HEX Editor.
Hope I will get it soon. Sorry for my bad English
Thank you
