Stock firmwares of Android 8.x for Nokia Phones required OST LA 6.1.2, but you still can't use it even if patched.

Here's the guide of how to flash stock firmware with OST LA 6.0.4.
Prerequisite: Your phone has bootloader unlocked, check this guide if you haven't:
https://forum.xda-developers.com/nok...lcomm-t3769930

You must use OST LA provided by heineken78 , which provided in the bootloader unlock topic.
(Right click on the setup.bat and run with administrator privileges)

1. Download the firmware provided by blackpanther0582.

Skip step 2 to 5 If you're flashing Nougat stock firmware.

2. Use this unpacker to unpack this firmware into multiple files:
https://forum.xda-developers.com/gen...-tool-t3699464

3. Use a text editor that supports Unix formats (e.g. Notepad++) to open the file with mlf extension.
4. Modify these values as shown below and save:
Code:
INITOPTION = 0x20000
INITDLTYPE = 0x60
SECURITY_VER = 0x0001
5. Use OST LA 6.0.4 to load that modified mlf file.
6. Check "Normal Download", "Clear user data", and UNCHECK "Check System AP status".
7. Put your phone to download mode by connecting your phone to PC when powered off, then click next.
8. You might see a prompt to tell you "Ask customer to try to unlock it first", it's for service point employees. Just ignore that and click Yes.
9. After firmware flashed, you might see an error with code 0xC6DA. Ignore that, close the OST LA and force reboot your phone by press and hold Power button for few seconds.
Quote:

That means the phone flashing result can't be sent to FIH server.

  
That's it.

Special thanks:

@heineken78 for providing unpacker and patch
@blackpanther0582 for providing stock firmware

Edit phoneinfo
How do you check "Normal Download", "Clear user data", and UNCHECK "Check System AP status"?
I cannot click on "Edit Phone Info", If I click on the button, the OST LA does not respond. However I can click on "next" directly, but later I met an error -Download fails
SE_ERR_ADB_CMD_GET_FAIL_RESULT (0xC6DA).

After reboot. Nothing changed...

P.S. I just want to root my phone TA-1052 with slot A on sep SP and slot B on oct SP.
I have tried all the possibilities, even the downgrade does not works...

Whenever I try to unpack the NB0 (Nokia 7 plus TA-1046) file using the NB0 tool v3.4, it always gives me an error (see screenshot) and if I click on "Continue", it gets stuck in halfway.

Yeah it seems to be a problem on my PC. I gave the firmware to someone else and he was able to unpack the firmware.

If you mean the solution for the OST LA, sorry but no solution for the moment it seems.
