Huawei P8 Lite bootloader locks itself

Hi guys, I have a P8 lite here with a problem: it stays stuck on the huawei logo. So I'm trying to flash a new rom to solve the problem.
I went to the huawei website, obtained the oem code, then i proceed with
fastboot oem unlock CODE
output OKAY, the phone changes its status to UNLOCKED
then I
Fastboot reboot
and the bootloader it LOCKED again. Do you know why this happens? Could I try to flash twrp right after the OEM UNLOCK without rebooting?

Hello,
take a look at the UNIFIED HELP THREAD,
post#6 ---- UNBRICKING AND DOWNGRADING FROM EMUI 5
where it is well explained how to use the rollback package.
You need the marshmallow version of your ROM stock.
Ex: VNS-L31 Rollback Package + VNS-L31 (C432 or C185 or others) B160 / 1,
depends on whether dual or single SIM or others available for your CUST / Region (C432 or others).
Follow the procedure carefully ...
Cheers

TWRP cannot be installed

In Huawei p9 lite VNS-DL00 I wanted to change the location to the European one to upload Android 7. I unlocked the bootloader using the PotatoNV method. When trying to upload twrp via both SRK Toll and minimal adb and fastboot, the error "FAILED (remote: image verification error)" pops up. How to solve this problem?
Ps. could it be related to the lack of oem lock removal options in the developer options and the lack of fastboot frp on the screen (only phone unlocked)?
did you try this?
