How to Fix Invalid IMEI Problem of a MediaTek Android Phone

How to Fix Invalid IMEI Problem of a MediaTek Android Phone - General Topics

Usually Invalid IMEI error occurs after you flash your MediaTek device. No need to worry as there is a simple fix for this issue. No need of root privileges on either method.
Method 1: (Works even if your phone a single error of Invalid IMEI or both if you have a dual sim)
1. Open dialpad and input *#06# (If a single sim is working you can see an IMEI and another is invalid, you can find invalid IMEI under battery of your phone)
2. Copy IMEI number.
3. If no sim is working you can find those numbers just below your phone battery.
4. Open mobile uncle, click engineer mode and chose android or mtk.
5. Go to connectivity, CDS Information, then radio information and chose the sim that isn't working, either one or two.
6. For sim 1 press phone 1, Click on AT+ on the top and type these AT+EGMR=1,7,"XXXXXXXXXXXXXXX"..... Here "XX.....X" is your IMEI number. Type it (make sure its in quotes). Now click send then reboot.
7. If invalid sim is sim 2 then click phone 2 and type AT+EGMR=1,10,"XXXXXXXXXXXXXXX" , click send then reboot.
Method 2:
Dial “* # * # 3646633 # * # * 2- then follow that path –> CDS info –> Radio info –> Phone1 (for the first imei) 3- at the top there is a command line which begins “AT+” just type there “AT +EGMR=1,7,”IMEI_1? (instead of IMEI_1 put your first imei number) 4- hit send command 5-if you done just reboot the phone, if you change the second imei go to step 2 and select “Phone2? 6-and enter the code “AT +EGMR=1,10,”IMEI_2? (instead of IMEI_2 put your second imei number) hit send command 7-reboot 8-Dail ” *#06#” Check Imei(onlyshow the first one)

IMEI invalid in CCIT S8 pro
I have a CCIT S8 pro chinese phone. which i have flashed two weeks later but now the problem is phones imei is showing invalid what should i do plz help me. Thanks in advance. Plz help.

Thanks this helped me to restore the imei on my phone

Cds information didn't occur

I've got info for first time: "This command is not allowed in UserBuild" because my ERGO A500 add by himself this AT+ command without space
Then I made some research and it's important to add SPACE between AT and + so it must be AT + not just AT+ like exactly like @subodhpoudyal wrote above

The best tool for fixing Invalid IMEI in MTK devices is Maui META. Google it.
When it is installed connect your device (make sure you have the correct USB drivers and debugging enabled in developer options)
The tool works on your phone whilst the device is in META mode.
There are many guides online on how to use it,
It works better than anything else and it is incredibly user friendly,

The Engineering mode method doesn't work on all phones. Tools like SN Writer, Maui Meta and hardware boxes / dongles (e.g Infinity CM2, Miracle box, NCK box etc) would prove more reliable. You can read up mod edit - blog links removed for many other methods

i have a problem
now i have a problem i flashed my phone lenovo a7010 and i've invalid imei and when i enter the engineering mtk mode there is no cds information option i tried alot and no solution

I WHOLE formatted my Cherry Mobile Fuze Q390 (MT6582) with SP Flash Tool. Then I flashed the official firmware of this device with SP Flash Tool. I don't have any backups because I am reverting to stock. Now the phone works fine but it does NOT detect the SIM card. Also, the IMEI is shown as "INVALID" for both SIM slots when I input *#06#. When I try to fix IMEI from MTK Droid Tools it shows (ERROR : pttycmd1 device NOT found!). Also, MTK Droid Tools shows (Baseband V -----). I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. So the device has no baseband or radio files right not and also the data/nvram/md folder has nothing in it. Although, WiFI still works perfectly except the annoying NVRAM Warning that I kept on seeing when ever that I wanted to connect to a network. Now the official firmware of Cherry Mobile Fuze Q390 does not contain any nvram.bin file. It does contain the BPLGU file but I can't seem to modify IMEI with SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. I tried using the MTK Engineering mode mode also and tried to write it using the AT+ code but it keeps on saying failed to send command. Probably the SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. only modify the IMEI when the baseband or radio files are already present on the phone. So I think the only way out for me is to flash a nvram.bin using SP Flash Tool or Flash nvram.bin+nvram.tar to MTK Droid Tools which I don't have. Any ideas whether I am on the track or not? If I am, then how can I get the IMEI back on my phone. As you people can see that I have tried a lot of things, so please suggest/advice accordingly and any help would be greatly appreciated.

Try using another phone's nvram.bin, which is illegal and modify the IMEI with SN Write Station or any other tools to correspond with that of your phone.

1. check your baseband with mtkdroidtool if it null,you just only use flashtool format it (whole flash) and up rom again,your baseband will return,imei still null.Now you can use mtkdroidtool to re-write your imei,or use Imei & SN writer tool for hard imei.
2.if you still have baseband,just can not write imei throw mtkdroidtool -> just use Imei & SN writer,please install full driver for your mtk devices, include cdc driver

I've tried all the other software like the IMEInSe writer, the MauiMeta 3g, MTK droid tools... none of them worked. But the method mentioned above worked for me.... now there wasn't any NVRAM error in the wireless notification.... The simcard can register to the network as well... this is flawless...
just to share... CPU version showed by the software was MT6572, but if i boot it in factory mode, it tells me its MT6589... I do not know which one is the right one, but the above methods worked for me.... Samsung S4 Korean (clone 1:1) mediatek. running JB Android 4.2.2..

One week after i brought my phone, I accidently formatted my device using sp flash tools and lost the IMEI/NVRAM. It has been a real pain for me to repair it because i was new to an mtk device. Finally figured out how to repair by doing many search. So I made this thread to share the working methods to help those people who are suffering from invalid IMEI
So let's start.
Always remember "Prevention is better than cure". If you are planning to flash a custom rom, First of all Backup your IMEI. Don't Trust that a custom ROM flash will not delete your IMEI number. because odds are it will. It's important to store your backup to external SD because some ROM flashing techniques will erase your internal SD. so the best way to keep your IMEI number is to take my advise and make a backup.
Some Video tutorials will be added soon
DISCLAIMER: Do not do try any of these methods unless your IMEI has been lost! Doing so may permanently corrupt your imei partition.

I tried this method but every time I tried, I was getting "Entre Meta Mode Failed" I am unable to understand why my device is not going into meta mode. I have written IMEIs and MAC IDs with this tool on Canvas HD, hell lot of time.
The process for Canvas HD is little different, I used to select both the database files, first "BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V6_P18" and then this one "APDB_MT6589_S01_MAIN2.1_W10.24" secondly I used to power on my device "Power On" msg was displayed on SN Write Tool.
I tried all possible scenario, selected only one database file, changed the sequence of selecting database files, tried to turn it off after hitting start but worked nothing for me.
When we select Database files the window opens twice, did you select same file both the times? And have you tried to write all the things together, means IMEIs, MAC ID of BT and MAC ID of Wifi in just one go?

Yes i select same file for twice name of file is given above in my post and i never try to write other things like bt address, imei same time but i want to say don't try to write bt address because it will show error every time when you try to write and i also want to say that imei number can be written with this tool but select only imei don't other things like sn number, wifi mac address.......etc. try one thing only at same time. means when you want to write imei then select only imei but you can choose sn and wifi mac address at same time it can be flashed successfully......

There are so many reason to occur the issue you mentioned
1) Virus/ malware infection
2) Contact database corrupted
3) Due to 3rd party application which share your address book such as Viber, line ets..
4) Sim card contact memory location having issue with data filed
5) recently you imported contact complicating or address book limit exceeded
Simply you can reset the device and most probably fault will be fixed but before reset the phone make sure all contact backup to the your google account.
Hope this answer help you!

I found a little thing that make that command failed; there's no space and no . (dot) within the command, so the command should be
AT+EGMR=1,7,"IMEI_1 NUMBER HERE"
that works with Lenovo A859

Hope it helps! Regards!

No permanent solution
It requires root. Also it's not permanent solution. After performing hard reset, imei are erased again. So give permanent solution.

I used Maui meta to recover my imei you guys could also try sn writer

Thank you very much (an original author and you)! Really.
( AT+ EGMR=1,7,"IMEI_1 NUMBER HERE" worked for Phone 1 and AT+ EGMR=1,10,"IMEI_1+8 NUMBER HERE" for Phone 2 ( IMEI1 + 8 ) )
Btw, a command *#06# shows two same IMEIs, but SIMs and dialling works. Is that okay?

What happens when I dont have my imei number
What happens I.don't have my original imei number
Dailing the 06 thing says invalid IMEi
The sticker on which the IMEI.number was is so faded I cant make out jack.....
The box is gone
Hellpppppppp????

MTK device IMEI null or invalid solution

install MTKEngineerMode app
Select Engineer Mode.
Select Engineer Mode MTK.
Select CDS Information from the Connectivity tab.
Select Radio Information.
Select the SIM you wish to change the IMEI on.
At the AT+ line for SIM 1, enter AT+EGMR=1,7,”THE-FIRST-IMEI-NUMBER”. For SIM 2, enter AT+EGMR=1,10,”THE-SECOND-IMEI-NUMBER”. Of course where the words are, you will enter a number.
NOTE: Do not forget the quotes surrounding the number
NOTE: If you get an error regarding “this command not allowed in user build”, then put a space after AT, so it reads for example AT +EGMR=1,7,”THE-IMEI-NUMBER”
