SXT LTE6 Re-installed RouterOs now can't connect to SXT

SXT LTE6 stopped recognizing the SIM so re-installed RouterOS 6.48.4 and rebooted.
Now can’t access the SXT and Winbox and Netinstall no longer able to find SXT.
IP address unknown and on Wireshark only shows LLDP and CDP packets without IP address.
How can I find IP address to access SXT.

After netinstall unit not have any configuration, means no default 192.168.88.1/24 with DHCP Server. Webfig (www panel) not work when you not have IP Address at unit.
You must connect using WinBox app or Mobile app thanks to discovery and connecting via Layer2 by Mac-Address (no Layer3 IP Address).
