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.

Hello all,
first to all who will say I must read the forum for problem solving - I did but from all the info out there it was simply too much. So I decided to start a thread in the hope that somebody will be able to help me.
So I have a corrupted nv_data.bin in my /efs folder but I still have backup of this file. But only this file.... I know - totaly dumb... I installed new JPX and after trying to change the product code from KOR to MOT (Slovenia) I accidentaly deleted nv_data.bin. I of course tried to replace it thru Astro Mate (I did had rooted phone - Darky's 6.0 was working fine ) but everytime I tried copiing this file tt didn't copy actualy - It said copied but the old file remained there - I know this because the Productcode didn't change. So I deleted the file thinking that this will help and tried to copy again. To my bad luck it didn't. I tried to copy and everytime a new file was created instead. also renaming a bakup file in this folder was not succesfule - it said Fald to rename file nv_data.bak. Since then my SIM card is not recognized and when I check what Baseband version I have it it written Unknown. So I tried even with ADB Shell, use busybox and when I eneter cp /sdcard/nv_data.bin /efs it says Now enough free space??? So I don't know anymore what to do. Does somebody have an idea what I can try to solve this? Please please please? I will donate to the one who helps me saving my SGS.
Thanks,
Borut
Hi !
This is because the file is used by the system.
Safest method:
- Reboot into recovery (make sure you have root in recovery)
- do what do need to do in recovery
- Reboot in normal state
In recovery phone / baseband / RIL are not started.
so you mean when I boot in recovery i can copy the file using adb shell? Or how do you mean I can do what I must do?
I have done it before while the phone is on, but you have to enter flight mode, set the correct owner and rights and reboot afterwards.
Well, regarding ownership and stuff like that - I'm a tootal noob
Help please NV_Data.BIN
I know this isn't the place to post this but I have been trying since yesterday afternoon can't figure out where I should post it to I keep getting an error that due to spam I can't post to certain areas without having 10 posts.
Please help -
I am not sure what to do now. I changed the rom on my phone to put 2.2 on it a while back. I never saved any of the files because I was not aware to. Now I am trying to go back to stock already used the one click Odin program and I have the original stock firmware on it. But when I try to update via kies mini it will not show up. I have searched And found multiple postings related to the fact that the product id and imei could be incorrect and you would need the original nv_data.bin file. I have searched through windows explorer on the phone but can't seem to locate one. Is there any way that I can get a copy of the original folder for /efs/nv_data.bin and any other files that are needed?
I have the Samsung Captivate on AT&T currently running 2.1
BaseBand: I897UCJF6
Kernel Version: 2.6.29 [email protected] #2
Build number: ECLAIR
You need to check your IMEI matches your original .
You have stock rom stock as in not the network supplied firmware that came with the phone ..
Windows explore is no good you need something like root explorer .#
I can get a copy of the original folder for /efs/nv_data.bin and any other files that are needed? Not unless you saved them they are phone specific .
Worth doing a factory reset before you make any step as that may solve your problem .

how do I check the original imei? I didn't backup the files as I was not advised to in the information I found online at the time (couple months back). I have done a factory reset via the phone (privacy settings) a couple times now and still when I plug into kies it tells me Unregistered device.
This is very simple to fix if you have nv_data.bak in the EFS folder.
If that file is present then you can safely delete nv_data.bin and reboot the phone.
A new nv_data.bin will be generated.
how do i know if I have nv_data.bak? where on the phone would I find it and how?

It should be in the efs folder (unless you've done something to delete it). As said by JJEgan, you will need root explorer. Navigate to it in the efs folder and copy it to the external sd card and then keep it safe somewhere.
how do I check the original imei?
Its on the box and or with the receipt .

The Baseband problem started when I flashed ICS euphoria from toxic 9.
I tried stock>cm7 initials>ICS passion> euphoria>slim, stock>jetpack the same problem IMEI is 004999010640000 or unknown.
The efs folder contains lost + found folder and unable to delete it. I also tried EFS pro to restore EFS. But nothing works coz the nv_data.bin is used and generated by some process. I will attach the nv log file.
Help !!! I am stuck in froyo (The IMEI NO is correct and the phone works in froyo coz nv_data.bin can be replaced easily)
Solved it by deleting all the files in EFS folder and replacing it with back up files.
The phone should be in flight mode. Then restart the phone.

U need a root explorer app and of course root! Also
The steps are little bit tricky...
Step 1
Make a copy of your EFS folder on your sdcard using root explorer and then backup to your computer [ to have another copy if you have to format the sd card sometime ]
Step 2
Delete the EFS folder (Make sure you have the BACKUP in a safe place as mentioned in STEP 1) from the root of your phone using root explorer.
Step 3
Do a Factory Reset. After that, navigate to the root directory of your phone.
Step 4
Go to EFS folder using root explorer; delete “nv_data.bin” and the “nv_data.bin.md5” files.
Step 5
Go to your backed up EFS folder on your sd card, copy the “IMEI” folder to the EFS folder at the root of your phone, then again go to the backed up EFS folder in your sd card and copy the ” .nv_data ” file to your EFS folder at the root of your phone using root explorer.
NOTE: the dot in first of nv_data is not a mistake, copy the “.nv_data” file.
Step 6
Make another copy of the “.nv_data” file in EFS folder in your phone, so you would have 2 copies of “.nv_data” in EFS folder.
Step 7
Rename one of “.nv_data” files to “nv_data.bin” and another one to “nv_data.bin.bak”
Step 8
Open Command Prompt in your Windows PC (Terminal for all you Linux users) at the ADB tool path, or run Terminal at your phone enter these commands:
adb shell (use this command if you use ADB, if you’re using terminal, skip it )
su ( When the option comes up allow the superuser to access the file system by clicking “grant” on the phone screen )
chown 1001:radio /efs/nv_data.bin
Step 9
Reset your phone…. after that you have your original IMEI. you can check your IMEI by dialling *#06#.
You have successfully recovered
It seems to me the nv_data files are not present in the efs folder.
I was just going through steps but I didn't find these files.
I have backed up the files before flashing the phone using the twrp & Samsung tool box. But in both of the backups there is no nv_data files available. N currently in efs folder there is no no_data file.
the dot in front of .nv_data means they are hidden. you probably won't see them

I got this error after restore my Rom by a backup (Nikalli Rom). What is this?
Try to restore again or flash rom again.
By the way which ROM are you using??
I also had this issue when I flashed stock ROM using SP Flash tools. I had lost my IMEI number.
I restored it using MAUI META
Please check if you have IMEI
Dial *#06#
I have solved it using this topic:
Many MTK device's users are facing the WiFi NVRAM WARNING err 0x10 Problem by formatting the whole flash by SP Flash Tool.
After a long time I Found a Solution for mtk Users to solve the problem.
This method is easy as any other methods..
What you need to perform the methods..??
1. A Rooted MTK device
2. Root Explorer.apk
3. Wifi Error Fix.rar
How to do this?
On Your Rooted device go to root Explorer
And navigate to File system root/
data/nvram/APCFG/APRDEB
There you will found to files named 1) WIFI , 2) WIFI_CUSTOM just simply delete these files
Now extract the files from the WiFi fix.rar
and move the extracted files to the previous (root/
data/nvram/APCFG/APRDEB) folder.
After this process complete You need to just reboot your device. Now go to the wifi adapter setting and you will find the message of NVRAM Error Warning is gone...
I tested this on my Micromax A89 Ninja(Mt6577).
If I helped you all just say thanks by hit the :good:Thanks Button...
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.
