Hello everyone.
Thanks for all your efforts on this website, i've tried to unlock the bootloader on my Itel A49 A661L but it didn't work,
I followed this method but resulted in an error (https://www.hovatek.com/forum/thread-32287.html)

Here's the inbut:
  1. ~$ sudo -i
  2. ~# sudo usermod -aG plugdev root
  3. ./fastboot devices0765740239000778 fastboot
  4. ./fastboot oem get_identifier_token2...(bootloader) Identifier tokenSadbootloader) 30373635373430323339303030373738OKAY [  0.022s]finished. total time: 0.022s
  5. ./signidentifier_unlockbootloader.sh 30373635373430323339303030373738 rsa4096_vbmeta.pem signature.binIdentifier sign script, ver 0.101+0 records in1+0 records out48 bytes copied, 0.000574723 s, 83.5 kB/sIdentifier sign successfully
  6. ./fastboot flashing unlock_bootloader signature.bin2downloading 'unlock_message'...OKAY [  0.010s]unlocking bootloader...FAILED (remote: Unlock bootloader fail.)finished. total time: 0.113s


Then I looked up in the vbmeta which i unpacked directly from the same firmware pac i did today.
Firmware:Itel_A49_A661L_V024_221021_11_SPD
Here are the results:
