[E1] Bootloader Unlock Problem (important!)

So. I would like to unlock the bootloader. All fine, I get the code, and when I type in
Code:
fastboot -i 0xfce oem unlock 0xcodehere
it says
Code:
FAILED: Command did not succeed.
However, when I do it the second time (enter the command right again) it says OKAY but the device will end up on a bootloop next start, and when I try to flash a kernel, it says not allowed.(fastboot) If I flash when unlocked without restarting device, the device will shut down at SONY logo. Is it possible that I got a temporary unlock? How could I unlock the device successfully?(permanently) I tried it with Flashtool, and the same results. I literally tried everything. I also cannot install the permanent OS-independent CWM because of the shutdown at the SONY logo. I didn't yet contact my service provider, but I don't think they would like the idea. I really want CyanogenMod on my device, and I'd also like to fix some problems if I can. Please try to help ASAP. Thanks!

I have the same problem. Did you resolve it?
Open Phone and dial *#*#7378423#*#* go to Service Info->Configuration if Rooting Status says Bootloader unlock allow: No you can't unlock it. If it says Yes go to Sony's official website for unlocking and follow the instructions.
Good Luck.

Unlocking Bootloader AGM M5

I've been trying for awhile now to unlock the bootloader on my AGM M5. It is running on a simplified Android 8.1. I've enabled USB debugging and have enabled Bootloader Unlocking in settings. ADB works fine but I cannot get the bootloader to unlock when I run the following commands.
C:\platform-tools>adb reboot bootloader
C:\platform-tools>fastboot oem unlock
...
FAILED (remote: unknown command)
finished. total time: 0.000s
C:\platform-tools>fastboot flashing unlock
...
FAILED (remote: unknown command)
finished. total time: -0.000s
I've tried running them from several different devices. Windows 7, Windows 10, and Raspberry Pi. But they all gave me very similar results.
If someone could give me some help it would be great. I'll mention right here that my ending goal is to install Postmarket OS. So if this is totally an unnecessary step please let me know. The reason for this step was I was trying to get a boot.img from the device and I wanted to install TWRP. But I was running up against every direction it tried and all my research was yielding very little as it seems that my M5 is not a very popular device.
