Bootloader is unlocked, fastboot returns ''FAILED (Remote: Verify state locked)

Question

I am trying to root my Vivo V11 with Android 10. The bootloader is unlocked. It says so in the dev settings, and I have to go through the warning prompt every time I reboot my device. When I run the fastboot command to flash the patched_boot.img file, it returns:

C:\Program Files\Minimal ADB and Fastboot>fastboot getvar unlocked
unlocked: yes
finished. total time: 0.002s
C:\Program Files\Minimal ADB and Fastboot>fastboot flash boot patched_boot.img
target reported max download size of 134217728 bytes
sending 'boot' (38579 KB)...
OKAY [  1.269s]
writing 'boot'...
FAILED (remote: Verify state locked)
finished. total time: 1.276s

Things I've tried to troubleshoot:

Running cmd as Administrator (im using win10) Confirmed OEM unlocking is turned on in the dev settings (it is, it says "bootloader is already unlocked" Confirmed USB debugging is on Disabled "Verify apps over USB" and "Verify bytecode of debuggable apps" in the dev settings. Confirmed file transfer is enabled from my PC and my Phone (it is, I can transfer files back and forth between them) Tried a different USB cable

Does this answer your question? Android Verified Boot and generation of vbmeta image — alecxs, Jan 15 '21 at 09:02
@alecxs I tried flashing a empty vbmeta.img but while flashing it the result is still same. While writing 'vbmeta' it says failed verify state locked — Ayush Jhinkwan, Jan 15 '21 at 10:22
@alecxs i have edited the post for results it still can't verify — Ayush Jhinkwan, Jan 15 '21 at 10:40
try fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img and don't use Powershell btw, run C:\Windows\System32\cmd.exe as Administrator — alecxs, Jan 15 '21 at 10:51
@alecxs still same error. Does it has something to do with device. I have Vivo V11 with android 10 — Ayush Jhinkwan, Jan 15 '21 at 11:00
readback boot + vbmeta from SP Flash Tool. open the dumped files with hex editor and double check the dumps are identical with stock ROM (to confirm the scatter file fits your phone) - then - and only then - flash vbmeta_disabled.img from SP Flash Tool. always make sure to flash in *"Download only"* mode only. always uncheck preloader. try to boot. finally patch the dumped boot with magisk manager and flash magisk_patched.img — alecxs, Jan 15 '21 at 11:16
