[General Questions and Answers] Assassin Iron Man:
I want to unlock my bootloader for custom ROMS and rooting but ran into some problems during the process.

When I run "fastboot oem unlock" and some other variations of the command, it gives the error "FAILED (remote: unknown command)" and I've tried several things to fix it.

I already tried using the official SDK Platform Tools newest and older versions, and Minimal_ADB_Fastboot_v1.4.3.

I've also tried switching from Windows 10 to a Windows 7 VM but that didn't help.

In case anyone thinks it is, I can tell you right now it is NOT a T-Mobile variant.

I used this guide: https://xdaforums.com/t/howto-unloc...cept-t-mo-via-edl-mode-easier-method.4077105/ (and got stuck on the oem unlock part of course)

Here is "fastboot getvar all" log for anyone that can read it:
