Can't flash TWRP with unlocked bootloader - Huawei P9 Lite Questions & Answers

Hiii,
I've read many threads but didn't find my answer, I have an unlocked bootloader but can't flash TWRP recovery.
Tried many different versions but all tries give me an "remote: image verification error"
Device is fastboot mode:
C:\Temp>fastboot devices -l
4<serial hidden>7 fastboot
Bootloader unlocked with official unlock code:
C:\Temp>fastboot oem get-bootinfo
...
(bootloader) unlocked
OKAY [ 0.006s]
finished. total time: 0.007s
Flash TWRP (failed) and flash STOCK (success):
C:\TEMP>fastboot flash recovery recovery_twrp.img
target reported max download size of 471859200 bytes

same with me ?

Try to relock and then unlock. I've had this problem too after downgrade to mm by official Huawei rollback package. Then phone and other tools shows than phone is unlocked and it was unable to flash recovery.

if it says wrong password it means you got the wrong password. it will say it's already unlocked if you try unlocking it while it's unlocked

My phone was unlocked with Potato v2.0.1, with working TWRP, rooted etc...
I solved this problem that arose after unsuccesfully install custom Rom, restore backup of stock rom, install update through dload and many many other attempts at improvement of my smartphone :-( No more time again!!!
Probably installing update through Dload will relock bootloader, but in the fastboot mode it says bootloader still unlocked.
Before I did all this, I had an original stock rom.
1: Relock bootloader with PotatoNV v2.0.1 (You need to open case and connect tespoint by wire - look on Youtube, i´ve find it there, also you need "Huawei testpoint drivers")
2: Factory reset
3: Install any update stock rom with Dload (Vol up + Vol down + power)
4: Factory reset
5: Developer options-turn on OEM unlock and USB debbuging
6:Unlock bootloader with PotatoNV v2.0.1 - keep password generated by Potato
7:Multitool 8 for Huawei - in the bootloader state unlock bootloader again - use password generated by Potato
8:Multitool 8 for huawei - install TWRP - it says "Succesfully installed" - TWRP works, root is possible. Yeah!!!
May be this is not right way to solve this, but for me it workś..

Stuck at FASTBOOT Zenfone Selfie/Zenfone Laser (Z00U/Z00T)

Hey guys, i wanted to unlock bootloader, and so i UNLOCKED BOOTLOADER, FLAHSED TWRP, TRIED TO FLASH CUSTOM ROM.
the twrp compared tz version and ended up in an error, so i searched online to know that, we need to update the system.
so i flashed recovery.img on top of twrp and rebooted where the fastboot got lost and ended up in a dead boot.
no vibrations, no led, no charging, no fast boot.
then i flashed using qfil using qualcom husb and got back the fastboot.
but this time, in fastboot, when i try to flash boot, system or recovery, it says, ::ARTITION TABLE DOES NOT EXIST.
so i tried to flash the gpt_both0.bin file as partition, and gave an error message of::: CANNOT FLASH THIS PARTITION IN LOCKED STATE.
i tried to fastboot boot twrp.img and ended up::: UNLOCK DEVICE TO USE THIS COMMAND.
so im pretty much got my bootloader locked and im unable to unlock it so i can flash stuffs.
the question is, how to flash the bootloader using fastboot so i can flash the rest and continue/??
