[solved] Can't access neither via ssh nor serial after vlan edit

Hi! I'm russian, so I can make some big mistakes in word semantics, but i'll be simple:

I've made a big mistake by splitting VLAN's in SWITCH settings of my router (asus rt-n14u).
I've changed CPU port to OFF in both of VLAN (1 and 2) than press "SAVE AND APPLY".
After that I can't access router neither via ssh nor serial after vlan edit. DHCP not working.

Via serial I can watch bootup process, but I'm Unable to send data (keyboard not working, Putty won't accept any keystrokes). Log is here:

I'm using this firmware:
[openwrt-15.05.1-ramips-mt7620-rt-n14u-squashfs-sysupgrade.bin]

Switch off hardware handshake for the serial port.

https://openwrt.org/docs/guide-user/troubleshooting/failsafe_and_factory_reset

Misconfiguring the switch won't affect serial. Unplug the Tx and Rx wires from the router and connect them to each other. That should echo back whatever you type in the terminal, showing that your converter etc is working.

Failsafe and factory reset should work for you just fine as mentioned above by @slh

I've tried connecting via XON\XOFF and NONE handshake. No results.

I've spent whole evening trying to access "failsafe mode" - no results. Device is not acting on RESET button click.
Factory reset can't be done because I can't access SSH on this device.

Will try now replacing Tx\Rx wires.

Thank you all very much.
The problem was in my UART wires configuration, I've messed up with wire color, put 3.3V instead of RX.
