after that you can use the code.
after repair you can restore original firmware from backup whit cm2qlm.

Thank you for your answer. I previously created the backup. I believe the file for this model exist in infinity support, I hope infinity support could confirm if yes or no. If yes I hope they could provide a link to download. Now the flash filled support is closed, I think is not good for users. My last option is use your suggestion. One more time thank you for your cooperation.

What do you mean "flash filled support is closed" ?
You can make search in support area by word Oneplus

I have logged in , i have access to Best files but for infinity I have message “Maintenance in progress”.

I do not see any problem with support area.
Where do you see message “Maintenance in progress” ?

Now is ok, but when I previously checked give error.

Unfortunately in support don’t have 4.4.4 version.
