Silly question but you did use other microSD's right?
There is no silly question !
at 6:30 you will see that I was sending biskeydump.bin
This payload(or hekate payload) does not require any sd card to be inserted at the boot step.
On the command line screen you will see that it struck after sending payload to the console.
It is not about the USB 2/3 port.
I tried 4 different ports on my pc, same result, 2 consoles work, 1 console does not work.
I did try my best to cover in the video that my other console(at least 2 but only recorded 1) work fine on the same environment.
In fact, I have never failed to send payload to my 2 other consoles at all.
I also verified that it was on RCM mode (APX device).
I also tried different payload, show you the checksum of the file to make sure that the files are not corrupted.
I have no other idea what might be the error from user perspective.
