ESP 880 file password protected and DSP cannot remove

Hello CSP experts,

Please help.
I have a ESP 880 with a file and DSP password protected, although I have done a NP F via RS232, i was able to scan the new default ip but trouble is i am having the RED led, i think the only way is to upload a new clean project. But because the device has been loaded with a password protected file, even if i scan a new project to upload, the password dialog box still appear and prompt for password. Any idea how to break this password protection. Thank you for your attention
