Hello Guys , 
                      I recently flashed my Moto M XT1663 with SP flash tool . I formated and then downloaded the rom . I had previously made nandroid backup with TWRP but lost it . The nvram partition is empty now and it created empty MP0B_001 file . I have no IMEI now .

I have tried various methods provided in our site and other sources but none of them worked .

All the Meta Mode tools like Maui Meta , Modem Meta , SN write Tool and various others gets error at get kernel port and fails . I installed the drivers correctly(Mtk preloader , Android cdc , Mtk debug , Mtk modem , Mtk usb port ). The preloaders port passes and hanshaked ok . The meta methods doesn't worked for me and doesn't get past preloader handshake .

I used the imei creator tool to create MP0B_001 file but it creates 24 byte files which are no longer valid . The current valid file is 120 byte .

I tried miraclebox , it strucks at please hold power key to connect to phone after detecting preloader port .

The Nck box doesn't have the MT6755 chipset option.

The GSM aladdin box or something , it doesn't even loads , yes I clicked the loader , a cat image prompted with run but it didn't run at all.

The infinity chinese box installs but doesn't opens up.

I feel exhausted now . Couldn't find any possible ways .

So , I request , If there is any XT1663 users out there , please provide me with the backup of your nvram partition via twrp or some other recovery and also the MP0B_001 file under /nvdata/md/nvram/nvd_imei/ . I don't want to or authorised to use your imei . I need it to work with for creating new nvram.bin and MP0B_001 files througth this interesting article :

Manipulating Nvram and MP0B_001

This is my only way. 

my nvram is all empty ( filled with zero ) , the MP0B_001 file is invalid and kind of empty , as the nvram itself is empty .

Please Understand , I don't intend to use or steal your imei or something like that . I just need non zero files to work with .

I'll be waiting . 

Regards ,

while waiting for someone who's has the device and willing to provide nvram backup
can you attach a screenshot of miracle thunder's error?
also did you try the other methods that require root? e.g adb method. it may not be permanent but at least one should work to at least get your device to receive network signals

First of all Thank you very much for replying quickly.

My phone is rooted with Magisk . I tried the adb method , it didn't work .

I have attached the miracle box screenshot.



After detecting preloader port , it instructs to hold the power key to detect the but it stand there forever . After a minute , I released the power key , the phone directly booted into system .

I tried the NCK box adb method with some random chipset since my chipset was not available in the option , 

it resulted ,

Device have root 
"/data/local/tmp/expl": error. Only Position Independent executables (PIE) are supported. And the device rebooted , nothing happend with imei..

I also tried to edit the MP0b_001 file , with info from this valuable source :

MP0B_001 info

Hexdump of my MP0B_001 file :

Code:

E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72 E9 1A 0B 2E 17 95 BD 0F 8B 86 53 72

As from the source info , the MP0B_001 file is empty with no imei .

so , I used the imei tool to create 24 bytes MP0B_001 file (12 bytes if 1 imei , 24 bytes if 2 imeis).

With hexeditor , copied the 24 bytes of MP0B_001 file and overwrited the first 24 bytes of the 120 bytes MP0B_001 file.

copied the modified file to phone , put it in the correct directory . set the user , group and read and write permissions and selinux context.

Restarted the phone , no chane in imei .

So , I booted into twrp , formatted Cache , Data , Dalvik and rebooted , Still no change in imei .

When I dail *#06# , it shows IMEI heading and empty space and a ok button.

No success yet ,

I tried all the other methods , none worked for me so for , I iterated many times with different computers and usb cables .

I believe it has to do something with the nvram partition. SO , If any XT1663 user out there , Please consider ...

still hanging on , 


Thanks again for replying.

Lets re-visit Modem Meta briefly.
Launch device manager then setup modem meta and return to device manager so you can see what happens when you connect the phone.
I want to know what the phone gets detected as while modem meta is working
BTW, any luck with Chamelephon and Tool Hero?

The Miracle Thunder 2.82 worked , the imei is fiexed now.Truly a Miracle , box , well , not really a box cause I used the loader version .

Flashed the stock firmware , used the miracle thunder , the imei got fixed .

But when I unlocked the bootloader to analyze what the tool has done , the imei vanished and no imei , the nvram is empty and so does the MP0B_001 file .

I would like to investigate further by using the miracle box on the unlocked device and analyze what the tool will do , but I have to return the device for now to my father . I will report back when I get my hands on the device again.

But for now , I locked the bootloader and used the miraclebox imei fix .The Imei is fine for now .

Thank you all very much for your time and effort .
I am really sorry for my typing errors .

I've attached the screenshot of the resolved device imei,.

Thanks again.
