Yes, I am back on 56S after testing the EUI 6 CN firmware. If factory reset does not work (SETTINGS, VOL +, CH +, CH-, VOL-, POWER), then:
Install the letvupgrade938.bin file from 4pda (Firmware for X4-43, X4-50, X4-50 Pro, X4-55 (Russian division of R & D) Version: 5.8.218T_1114), by adding it to a USB device and turning on the TV with the bin flash method (SETTINGS, VOL +, VOL-, CH-, CH +, POWER).
Set that up, and then install the US 56S zip with offline update option via a USB drive(hit yes when it warns you of US locale).
After the flash, factory reset it with the SETTINGS, VOL +, CH +, CH-, VOL-, POWER combination and you will be back on the US firmware. This worked for me.
