I have TM-AC1900 bricked by abnormal cfe bin flashing.. result(only USB LED lit)

I try uart connection.. (no response)

How to solve this problem.?
JTAG?
Or Broadcom ISP?
flashing cfe by ROM writer?

upgrade firmware again by ASUS tool when TM-AC1900 at resume mode.

If you've messed up the cfe, buy a new router.
