It seems obvious but I forgot to say that we must go into debug mode and plug the phone into the pc
I hope you will solve your problem :good:
Hello,
when starting my Phone in fastboot mode, it will be detected as USB serial device, and Qualcom NTV Tools recognizes the device. As soon as I click on "connect", an error message appears stating that the device cannot be connected.

Is this a known issue? I searched for in on the internet but couldn't find a proper solution.

Thanks and regards,
Helmut

Have you restored your phone by flashing a MM based KDZ? I couldn't get the program to recognize my device when I was running the Nougat Beta so that might be your problem.
I you have restored your phone with a MM based KDZ but the program still doesn't work properly, make sure that you have enabled Debugging mode, you could try an other USB port to.

The first step with the phone app is important. Personally, I fixed my IMEI with Nougat and it works
You should not be in fastboot mode but with the phone turned on.

I solve the problem! Now i have my imei back! Thanks a lot to @Pif0u and @Mr.FREE_Bird. :D
The problem is that the program efs professional doesnt work on windows 10, i try on windows 7 and it works with nougat firmware so the problem isnt the firmware.

I am really happy to hear that!
But I don't know if it depends on which Windows version you are running, for me it works just fine on Windows 10 but I can't get it to connect with my phone when it runs Nougat. But @Pif0u could get it to work while the device runs Nougat... so I guess you need a lil but of luck. Happy for you that you sorted it out and that you got your device fixed. :good:

Well, if you are in TWRP you could flash any MM based ROM without any problems. Just make sure you do a complete clean flash. :good:
EDIT: I almost forgot to mention that before you flash a MM based ROM you have to install a MM bootloader and modem!

I've been able to boot into fastboot. Can I do something from here?
Depends on if your bootloader is unlocked or locked. I need a bit more information, is your IMEI intact or has it turned into a "0"?
If your IMEI is okay, you should be able to unlock your bootloader if it isn't already and you should be able to boot or flash TWRP.

I guess my IMEI is wrong because i cant flash the unlock.bin and my bootloader is locked because of that guide i followed before. Is there anyway to change the IMEI via fastboot or using any other program?

At the moment I haven't found any way to restore an IMEI via Fastboot, sorry to say that. I quess you can't access the Download mode and you aren't able to boot the phone?

Try it in fastboot

Code:
fastboot erase userdata
fastboot erase cache
fastboot reboot
Already tried that. Can't do that because the device is locked

Is there a way to flash via fastboot the stock rom?
