I have been trying to flash a patched boot image file (to install Magisk) using the fastboot command. My bootloader is unlocked.
But when I enter the command, it just doesn't write the image. It's blank until I remove the USB connection, and then it gives the following error: FAILED (Status read failed (Too many links)).
I've tried different USB cables, and also a different device, to no avail.

I'm not sure if it is worth mentioning, but when I boot up the device, a warning message shows up at the top:

Code:

"INFO: LOCK FLAG IS : UNLOCK!!!
WARNING: LOCK FLAG IS : UNLOCK, SKIP VERIFY!!!"

What does skip verify here mean?

download and use latest adb & fastboot binaries from within platform tools @ https://www.hovatek.com/forum/thread-17104.html
bootloader is unlocked, so verifying boot and recovery partitions is skipped

No luck there :-( The problem still exists.

Your model seems to require a signed vbmeta and images for flashing.
What's the device model?

Just as I suspected. Try flashing recovery.img or boot.img from your stock rom (extracted pac file) via fastboot.
Lets know if that flashes fine

Yup, it successfully flashed the original boot image without any problem.
(Ignore the first two attachment, I can't seem to remove them even after clicking the remove button -_- Would be nice if an admin was able to remove it)

quick questions, how did you unlock the bootloader? and does your device have a vbmeta partition? you can check if your pac file contains vbmeta,img

I had to unlock the bootloader using identifier token (this method): https://www.hovatek.com/forum/thread-32287.html
Yes, it has a vbmeta image.
