Since you own serial connection equipment you will be able to simply flash a functioning firmware as described in

https://openwrt.org/toh/tp-link/tl-wdr4300

in the section "de-brick or OEM installation using the TFTP and RS232 (serial) method" at the beginnning of the second third of the page.

don't worry you don't have to use serial, just use this method I've done it dozen of times

I know. But as the user is apparently connected via serial interface, there's no need to recovery blindly. One can stay connected and watch what is going on.

Bytes transferred = 8060928 (7b0000 hex)
original_product_id = 9410002
original_product_ver = 02
recovery_product_id = 43000001
recovery_product_ver = 01
auto update firmware: product id verify fail!

Solved!
I had a brick after I mistakenly upgraded it with 941 firmware, and after that it does not part TFTP on my 4300, but just pay attention to the message ... I changed with the hexadecimal editor the wdr4300v1_tp_recovery header!

Thank you all!
