Disable TLS 1.1 and SHA ciphers on MP56
How do I disable SHA ciphers and TLS 1.1 on the Mp56 phones?

I added the line:

static.security.default_ssl_method = 5

To the configuration file, to no avail.

Do your phone support this parameter?
Is the phone running on the latest firmware?

Kind regards,

Phone is running 122.15.0.107, which appears to be the latest.

It doesn't appear that the parameter works, since TLS 1.1 still shows enabled. How would I go about disabling TLS 1.1 if the parameter isn't supported?
