Hi , first your device is x552 model not x522 but never mind .
In order to fix imei you need to flash nvram.bin and you need to allow in scatter file nvram.bin to be flashed.
First download this firmware:
https://www.4shared.com/get/H9yvkOUoce/MT6795__Infinix__Infinix-X552_.html
Once you download , extract on Desktop , make new folder on Desktop and put just MT6795_Android_scatter.txt and nvram.bin which you can find in Extra files folder.
Now in order to flash nvram.bin you need to edit scatter file and enable instaling that file .
Here you have easy video instruction to follow:

If you solve the problem , edit this post as SOLVED!
Good Luck
Any One suffering from same problem, Below are Easy steps to fix Unknown Baseband version, NULL or Invalid IMEI and SIM cards / Network signal not detected on a Mediatek Android phone.
Before you proceed, ensure that your Mediatek phone has a valid Baseband (not NULL Baseband). If your Baseband is unknown then download the firmware for your model and flash using SP Flash Tool . Flashing the firmware to restore Baseband. With Baseband regained, you can then proceed with fixing IMEI.
You can use below mentioned tool to ENter EMEI again, But your mobile should show a valid baseband version or the below tools will not work.
SN Write Tool (SN Writer) method
Maui META method.

First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.
Good day People,
I don't want to beat around the bush so, I installed customROM works fine. then I reverted back to stockROM then IMEI is gone.
I tried the Engineering mode thing, I tried multiple IMEI Writers non of them works for me. I always have this error "meta mode entry fail" for some reason I don't know what to do.
I do have an MTK Based phone its dual Sim.

Thanks in Advance.

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.

we have a same problem.
I fixed my phone (FUZE) ... .
just flash the phone in Firmware with "SEC_RO" file.
Fix IMEI, at least for MT6589 Gigabyte GSmart Aku A1 (if *#06# show Invalid IMEI):
Call *#*#3646633#*#* Engineer mode, Connectivity, CDS Info, Radio Info,
Phone 1: AT+EGMR=1,7,"myIMEI" <send>
Phone 2: AT+EGMR=1,10,"myIMEI2" <send>
Hello @phaw16, @nandhu.crab19 : Can you resolve that problem?
I have the same here my phone is Blu Dash 5.5 D470u with mt6582 processor.
The meta mode is failed to connect. Drivers are ok.
Hello,
I have an Elephone P8 (2017). After flashing an ROM image to the device, the NVRAM was overwritten and the operating system reported no IMEI. To fix it, I used the SN writer tool to re-enter the IMEI numbers, MACs and serial and re-installed the latest stock ROM from Elephone.
The IMEI numbers are back again but for some reason, the mobile network connection is only available for a limited time after booting. 20-30 minutes later, no mobile network is available anymore until I either reboot the device or toggle the SIM to be used for the mobile data connection.
Has anybody an idea how to get a stable mobile network again?
Is there possible that anything else is wrong or missing in the NVRAM beside the IMEI numbers?
This sounds like you flashed the release-version 20170722, not the first update 20170831.
Recheck. If in doubt, format whole device with SP-Flash-Tool and reflash 20170831.
Hello,
I installed the 20170831 stock ROM but "about the phone" in the android settings lists a baseband version with an older data:
Base-Band-Version: MOLY.LR11.W1630.MD.MP.V9.3.P10,2017/06/26 09:07
Kernel-Version: 4.4.15 [email protected] #1 Thu Aug 31 11:28:07 CST 2017
Build-Number: Elephone_P8_V11_20170831
IMEI-Numbers: 3598500800XXXXX
IMEI-SV: 78
SERIAL: ELEE800....
Same problem

Hi GoaSkin,
I have the same issue than you. I also overwrote my NVRAM and restored my IMEI with SN writer tool.
(If anyone think he bricks his elephone p8 (2017), he should try to flash a test version (he worked for me, when all the other version didn't work) then reflash with a recent version. )
SMS and 4G Internet works fine but phone call (3G/2G) don't work :crying:. (sometimes when I reboot my phone, it works again but it is rare).
I have the same version of Base-Band than you.
I will try to flash other version, to test if it works for me.
I'll let you know.
I found advices in other forums that people have similar problems on other devices using "Moly Baseband". They managed to solve this issue by using a different version of the moly baseband file when using the IMEI tool.
When you use the IMEI tool, you need to submit the baseband file beside the IMEI numbers and MAC addresses you enter. The baseband file comes with any firmware image. I don't know which baseband version was installed before I bricked the NVRAM partition but it is possible that the pre-installed version was a different one to that which comes with the (newer) firmware updates.
Maybe it is worth to try to downgrade the baseband version which comes with an old firmware image or to try if it is possible to use a baseband image that comes with the firmware of a different device also using Moly baseband.
Furthermore I found out using analysing tools that the phone is still able to get some information of the GSM network. Possible the mobile operator closes the network link caused by bad network requests.
It would be so good of any one of you to help me for this problem;
Recently, using SP Flash Tool, I accidentally chose the "Format All + Download" option when flashing a ROM to my Lenovo A850. I managed to flash the ROM but the biggest failure is, I cannot call and use data connection. I also have an error called "NVRAM Warning: Err 0x10" at the Wi-Fi section. At my notification bar, it shows "Invalid IMEI".
My phone is Dual SIM.
I somehow managed to fix my lost IMEIs by entering EngineerMode. After fixing and rebooting my phone, my notification bar showed "Emergency Calls Only" but I placed a working SIM in my phone. I still could not call and use data. I am sure that I lost many important things (MAC Address, IMEI, NVRAM, etc.) when I formatted my phone using SP Flash Tool.
I am clueless on how to fix this problem. I don't know what I should do. I just want my phone to be able to call. If not my Lenovo A850 is useless. I am so frustrated now and I am so scared.
If any one of you are able to help me, PLEASE NEVER HESITATE TO HELP ME. This issue is so serious that it doesn't let me to have a peace of mind.
PLEASE I BEG YOU DON'T IGNORE THIS PLEASE!!! Thank You for your kind attention!
Hi !
In order to fix the "Invalid IMEI", you have to :
Dial *#*#3646633#*#* then go to "Connectivity -> CDS Information" then click on "Radio information" then if your phone is dual SIM, press Phone 1.
In the textbox with writen "AT+" click on it then select AT+EGMR=1,7,"" and between the quotes, write your IMEI 1 number.
If you have an error "This command is not allowed in UserBuild", simply add a space between EGMR and AT+.
It will look like that : AT+EGMR=1,7,"YOUR IMEI HERE"
And for the NVRAM error, simply follow this guide : https://forum.xda-developers.com/showthread.php?t=2730486
Have a good day !

Hi. Thanks for your help. I fixed NVRAM and IMEI. But still, I cannot call and use data even after I fix IMEI and NVRAM. The notification bar shows "Emergency Calls Only". I have inserted a working SIM Card but it is not being detected.
How will I get my phone to call?
Thank You very much!

Hi to fix that correctly , first root your device but fbefore that enable USB Debugging :
1. You can use KingRoot.apk , this one work for me if it doesn't work for you search for iroot.apk or frama-root.apk or some other.
https://kingroot.en.uptodown.com/android
2. Download SN Write tool ( we will use to put our Original imei number ).
https://snwritetool.com/download/sn-write-tool-v1-1752
3. Download MTK droid tool 2.5.3 (we need for restoring nvram backup) .
https://androidmtk.com/download-mtk-droid-tool
4. Download nvram backup for your device A850
https://mega.nz/#F!CQ1jjZSb!3wlZPapiIuRTuiqVWt4jKg
5. adbd Insecure v2.00 (install app just in case if your device is not recognized in MTK droid tool)
https://forum.xda-developers.com/sho....php?t=1687590
7. BusyBox.apk (install app just in case if your device is not recognized in MTK droid tool)
https://busybox.en.uptodown.com/android
Once you do that run adbd Insecure v2.00 app and check enable insecure adb now connect your phone on pc and run MTK droid tool , if is your device recognised press root to grant SU rights for root shell and click on OK.
now click on IMEI /NVRAM now click just on Restore choose nvram file which you downloaded put .bin file .tar file ignore and click on Reboot.
Now it should be working again .
To restore your Original imei , run SN Write tool go to System config check IMEI and check IMEI dual if your phone support dual sim and now load:
Modem DB and AP DB from data base folder which you can find inside your stock firmware make sure you don't make mistake by puting AP on MD1_DB or Modem DB on AP_DB click on Save now click on START , now you will see popup , write there your original IMEI 15 digits numbers click OK , take out the battery from your phone and put back now plug your device .
Once the process is finish you will See PASS your device will reboot and when is finish just exit from SN writter tool .
Follow this video if is easy for you :

Hey everyone, I need your help badly..
Device: Rmx2151
Android: 10
RUI:1.0
Bootloader: Unlocked
IMEI : NULL
Baseband: repaired
Problem level: software level(100% sure)
The Problem:
I can't use my sim card without wifi connect.
My nvram partion was corrupted, and so my IMEI and baseband was lost,(no backup)
I managed to recover baseband version by (as someone told me that it is mandatory to use sim card) deleting "nvram" folder from twrp file manager.
But my sim card still won't work, it only works when I connect to wifi, and as soon as i disconnect wifi the mobile networks also disappears,
Others who used the same method on this very device to recover baseband have a fully functional sim.
I also tried all other stock rom firmware files RUI1/2/3 A10/11/12
Heres how it looks:-
