Unknown Baseband + Null Imei

[AthulPrasad]

Please help me in figuring out how to fix the unknown baseband error with null imei for Moto E4 plus Xt1770 Indian version.

What i have done so far!!!

I flashed twrp recovery after unlocking the boot loader, flashed Lineage OS 14.1 custom ROM and rooted using Phh superuser. But as I was not satisfied with it, I reverted back to the stock ROM using SP flash tool " Format all + Download ". But ever since I have unknown baseband error. I cant go back to the custom rom. So Please help me in fixing this problem by staying on the stock rom. I am desperately welcome to all suggestions.

Do you get the null imei in the bootloader only? Or is there an imei when you dial *#06#?
Also provide pictures like this from cpuz

This is the solution for unknown baseband and null imei error for mt6737 device Moto E4 Plus.

This is fix for Moto E4 Plus Xt1770 Indian Version.

(Note: You must have adb folder in Local disk C of your computer. To make things easier if you paste the firmware folder of Xt1770 within the adb folder , things will run more smoothly. To know how to have adb folder in Local Disk C, just Google it.)

Fixing On Moto E4 Plus XT1770

1.First download stock firmware and flash it (Format all+ download).

2. Then run the phone once. You will be having unknown baseband error.

3. Nothing to worry. Here is the fix.

4. Again Open Sp flash Tool and Click On Scatter Loading.

5.Here Select Scatter from LK Folder (Already In Firmware Folder)

6.Click On Download. Switch off the phone and holding volume up and volume down button connect it to PC.

7.After Flash Switch On The device
Device Will be on Special Bootloader Mode.

8.Again Connect Device to PC

9.Open Firmware Folder

7.Run "hwflash" Bat.It is present in firmware folder.(IMPORTANT)

8. Next Download XT1770. (I have attached the file)
Copy That Bat File in Firmware Folder and run it.
AFTER THE BAT Runs,Type "1"press Enter.
( Note: If it just runs without you getting a chance to press 1 , that means adb is not there in Local Disk C. You can confirm by running the command "adb devices" from cmd. )

9.If things go correctly, you will get Press any key to exit command.

10. Now disconnect your phone.

11. Again open Sp flash tool and select the default 6737 scatter file( NOT the one in lk folder).

12. Now deselect all except preloader and lk. Click download. Your phone is still in special Bootloader mode. Power off and holding volume up and volume down connect your device to the PC again.

13. Once flashing is complete. Switch on the phone again.

14. You will now have baseband. If you still have null imei, fix it using Maui Meta tool from hovatek forum.

I think that is because you have a highly secured antivirus installed. Try disabling the antivirus. Also in Windows 10 , ensure real-time protection from Windows Update is turned off. And even after doing all this if nothing works, like I already said, check if "adb devices" command detect your device. If the command does not recognize your device install minimal adb and fastboot and copy the files to a folder created to a folder named "adb" in Local Disk C. For assuring 100% success you can paste the firmware files also in adb. Hope this helps.

Please help me in figuring out how to fix the unknown baseband error with null imei for Moto E4 plus Xt1770 Indian version.

Null imei or no baseband. your device nvram which contain radio functionality of device(imei, bluetooth, wifi etc etc) somehow got corrupted or formatted.

But as I was not satisfied with it, I reverted back to the stock ROM using SP flash tool " Format all + Download ". But ever since I have unknown baseband error.

*Format all* option erases data from all partitions. probably you lose your device nvram.

You can fix this by following method :
anyone in this forum willing to provide you their device nvram data can fix your device or you can fix this by using imei injector tool.

Backup your device nvram manually :
dd if=/dev/block/platform/.../.../by-name/nvram of=/sdcard/nvram.img
dd if=/dev/block/platform/.../.../by-name/nvdata of=/sdcard/nvdata.img

Install using this method :
fastboot flash nvram nvram.img
fastboot flash nvdata nvdata.img
