Serial console for wr841n V14 or how to recover device?

Hello

I've not found how to use a serial console for TPLink wr841n V14.
I've bricked a device while I installed with tftp the
openwrt-ramips-mt76x8-tplink_tl-wr841n-v14-squashfs-sysupgrade.bin
instead of xx-squashfs-tftp-recovery.bin
image because I've not found it in a thread

Or is there an other way to recover the device?
