HT-M02_V2 Blocked after upgrade and reboot


I try to upgrade my lor gateway MT-H02_V2 using this command:
rm -rf update_M02* && wget && chmod +x && ./
I add an error message : cp: cannot create regular file ‘/root/.func/watchdog’: Text file busy
I delete the file and redo the upgrade ==> all seems good.
I did a reboot and now my gateway is no more visible on my ethernet network …
How could I restore the system or reinstall or any clue ?
