Micro USB port on TX1 is broken.. How do I reflash L4T without Micro USB port

Hello guys

(sorry for my poor English ^^; English is not my mother language)

anyway I wanted to reflash L4T 32bit on my TX1

But Micro USB port on my TX1 is broken … so I have to reflash L4T without Micro USB port

so Is there anybody who reflashed L4T on TX1 without Micro USB ??

Is it possible to reflash it via USB 3.0 port?

The micro-B port is required for flash. There may be some difficult and expensive way to do the equivalent with a JTAG debugger. If the port failed RMA may be possible.
