Unlocked bootloader but I can't flash anything

I had unlocked bootoader for more than 1 year and didn't have any problem with it. But now for some reason I can't flash anything.
When I try to flash using TWRP i get ERROR 1. From recovery log:
Code:
Updater process ended with ERROR: 1
I:Legacy property environment disabled.
and when i try adb (not only flash but other commands like fastboot oem device-info aswell)
Code:
FAILED <Remote: command not allowed>
Any idea how to fix this?

try to unlock again, and check what it say will you try to unlock.
.
Note: The only file system that works with fastboot is the file system that you extract from update.app, only!
But doesn´t work if you flash with twrp, for twrp is the file system that you pull from the phone.

I know. Tried to flash stock boot img with fastboot and zip with magisk in twrp.
EDIT: I was able to flash boot.img after this, I guess it worked. Thanks!

I have the same problem again... But now unlocking bootloader again doesn't help.
Also reflashed twrp.

Anyone?

If you only want to flash boot.img you can do that in TWRP.

When I created this topic all I had to do to fix this problem was unlocking bootloader again.
But few days ago this problem occured again and unlocking bootloader doesn't help.

It's a bug. REINSTALL default firmware it 3 buttons, let it turn on. Unlock boot again and flash twrp. If that does not work either your phone is damaged or you did something wrong in the middle.

Try sending command "fastboot devices". Does a number appear? In that case, check your recovery_ramdisk img and directory

Download the files again and make sure you are correctly using fastboot

since you rebranded the device, you should unlock the bootloader again. fastboot doesn't allow running command with a locked bootloader
fastboot oem unlock yourcodehere

Dude, how many threads do you need to create, it won't make it any more likely that anyone will help you
Your problem is caused by that you only unlocked the bootloader and not critical partitions
Which stock rom were you on before flashing a custom one?

Are you sure?, if so, manually flash boot, system and vendor using fastboot to your current slot
Fastboot flash boot_a boot.img
Or boot_b if active slot is B etc...
Then go to developer options and enable oem unlocking, if you can't enable that option, lock the bootloader, enable the option then unlock bootloader and critical flashing

You need to enable bootloader unlock through setting in developer option enable oem unlock, and then you can use the ' fastboot flashing unlock'
You can't root with locked bootloader as it will show an error message your device is corrupt,
At you situation now you should flash stock boot and then the phone will open and then you go to settings as i mentioned to enable oem unlock through developer option in settings

Fastboot unlock bootloader with long command, you will see it unlock temporarily till reboot, flash boot.img and recovery.img, reboot into recovery wipe data & cache, utilize USB otg to reinstall rom.

Use "Fastboot fastboot oem nubia_unlock NUBIA_NX629J" to unlock the bootloader and flash the correct boot img. Or you can go to stock recovery flash the whole system. It is caused by an unsigned boot file.
