Good afternoon Hovatek! I have a 2016 Asus ZenFone 3 Max (ZC520TL) device in my hands. The official Asus utility for unlocking the UnlockTool bootloader is not available due to the antiquity of the device, the bootloader is locked, an appeal to Asus did not bring
The results, the method indicated in the topic did not help, the method with Magisk (BOOT firmware) failed. SP Flash Tool was useless in my case. Question to Hovatek: is there any other way to unlock the bootloader, using a script for example, or in some other way? or it's time to stop dancing with a tambourine and forget about the loader. I ask for advice, and also I apologize for the incorrect language (translated from Russian using Google)

Thanks for your Reply
Yes.I know. I enabled Developer Option and Enabled OEM Unlocking. But i think Gionee M30 can't unlock bootloader with fastboot comand.
You can find in your post about fastboot comand.
Do you have anyway to try.
Thank you very much
