Blocked bootloader

Hello. I have a VNS-L21 and when i tried to install a different Android version, it changed from C432 to C900. Now I have VNS-L21C900B160, and my bootloader is unlocked, but won't receive commands from fastboot, saying that the command has failed. The only command that works is "fastboot reboot". Can someone help me get that working? I would like to install TWRP and get back to the C432 region. Can anyone help me? Every idea is highly appreciated. Thanks in advance
get your oem unlock code again and type in fastboot : fastboot oem unlock yourcode ( replace yourcode with oem unlock code )

I tried this twice, second time after a wipe, but didn't work either way
Also, it says that it is unlocked, FRP unlocked, but at booting time, the yellow warning screen does not appear. So I don't know...

FRP unlock

Is there any way to unlock frp from the fastboot if the bootloader is unlocked and the device is bricked.
Already tried : fastboot oem relock xxxxx
Returns : command not allowed
I am on stock recovery and the device is bricked right now.
Help needed!Many thanks!

you can try this, I dont know how usefull it can be
I don't think there will be FRP because the V9 doesn't come with all the Google stuff. Unless, they were added afterwards by installing them all manually.

My PH-1 bricked ,I am so sad.What should I do?

question:
today I locked the booloader,but my PH-1 can't boot,it siad"Your devices is corrput,It can't be trusted and will not boot."
I use adb cant find devices.But it can use"fastboot decives".
"fastboot -w"is failed,the remote is "remote: Erase is not allowed in Lock State."
"fastboot flash boot.img" or "fastboot flash recovery twrp.img" also failed. the remote is "remote: Erase is not allowed in Lock State"
can anyone tell me how to get devices?

It sounds like the OEM unlock was turned off in developer settings.
If you can't get to recovery and you can't boot to be able to unlock again, you're stuck [emoji17]
This is a warning to others. Don't lock bootloader. You can leave phone unrooted, no TWRP, and bootloader unlocked. It has the annoying warning splash screen with every reboot, but a lot safer than locking bootloader

Exactly. This has been highlighted many times - relocking the BL after unlocking it once is a bad idea...
Shoot me a msg I May Be of help

For "Your devices is corrput,It can't be trusted and will not boot." Press power button?
Try
fastboot oem disable_dm_verity
Then
If able boot into recovery (hard reset button combination)
adb reboot "dm-verity enforcing"
Worth a shot ...
