If you factory default the mm2211 with a paperclip in the hard reset hole for 8 sec,
it should reply to 192.168.30.1 with login credentials super/sp-admin. Here are the
latest firmware code and control file to put on your FTP/TFTP server. Use the GUI
as it's much easier to use for upgrade, than the serial console CLI.
Thanks for a fast reply.
I alredy tried hard reset but the firmware in device both backup and main are customized.so hard reset not working.
Given links of firmware and control file are not working.
Please give me correct links for download. It would be helpful if there is a guide available for tftp or serial flashing.
