Bootloader unlocked but can not flash twrp recovery.img fastboot say Writing 'recovery' then nothing happend...

Device Model : Itel L6005
Processor : Unisoc SC9863a
Bootloader is unlocked, you can see attached image
I try to flash recovery with this command...

>fastboot flash recovery twrp-recovery.img 

the output is

Sending ‘recovery’ (23132 kb)           OKAY  [  1.029s]
Writing  ‘recovery’                              _       

and then nothing happend. I attached screenshoot you can see.
How to fix this problem.

Note :  My devices Ramdisk : NO     SAR : YES  That means I can not flash custom recovery with root access or magisk.
I need to flash custom recovery first for make root or other access...please help how to fix this problem.
Thanks in advanched.

It's Unisoc,
twrp-recovery.img must be signed
https://www.hovatek.com/forum/thread-32674.html

and you need custom signed vbmeta

In addition to what @Gargoyle said:
1. Reboot straight into recovery mode after flashing the recovery.img because once you boot up, the recovery you flashed will get replaced by stock recovery so adb reboot recovery would fail
2. Once you gain temporary root, you need to rename recovery-from-boot.p (in /system) to recovery-from-boot.bak else the recovery you flashed will get swapped with stock recovery once you reboot

I could not unlock my phone's bootloader with "Identifier Token" method. That's why I unlock my devices bootloader from a mobile store. Bootloader is unlocked but only stock img file is writing other img file e,g, recovery.img stuck at writing image. You said cusstom-sign-vbmeta file need to resolve this problem. The private key is required to create the custom-sign-vbmeta file. My device bootloader is unlocked, can I get the private key now? If the bootloader is unlocked, is it possible to get the private key somehow?
Please help if you know. Thanks for replying.

He already dropped a link above. If the Identifier Token method didn't work because your model uses custom keys (not the default one) then you can't sign any image and are limited to getting root using a pre-rooted GSI.

It would help to know what the mobile store did differently to unlock the bootloader

Can I flash pre rooted gsi rom in this situation? If it is possible I will do so. Please inform me is it possible?

The only thing that can be seen on the screen is that he used the Infinity-Box CM2 Dongle to unlock the bootloader, which does not use the token method and some information about the device, only the manufacturer has the OEM RSA key,

Vendor: Kingston OEM is definitely not the OEM RSA key you need, it's just the device storage information
