Hi. Kindly help if you can please. I'm trying to unlock the bootloader of Infinix Smart 7 HD and so far no luck. I tried This Hovatek Method on Linux and This Method I found online on windows but both failed. I followed all the steps and the device is being detected when I input fastboot devices command (when the device is in Fastboot) but ultimately when I use either Fastboot flashing unlock OR Fastboot oem unlock, I get the following error: FAILED (remote: 'unknown cmd.') fastboot: error: Command failed. On the Hovatek method on Linux, I'm able to get the signature.bin file after using the identifier token but when i run this command ./fastboot flashing unlock_bootloader signature.bin, I get this error downloading 'unlock_message'...okay [0.000s] unlocking bootloader... FAILED (remote: Unlock bootloader fail.)

The chipset is Unisoc SC9863A1. My end goal is to root the device. Thanks in advance.
