Earlier this month developer jcase from Sunshine shared with us a teaser picture of a S-OFF’d HTC One M9 but didn’t release the S-Off method then. Well, coming to end of the month, team Sunshine has now made the S-OFF officially available for HTC One M9.

For the unknown, HTC devices come with S-ON (Security On) by default and turning it off (S-OFF) involves a great deal of expertise, which is a thing of pro developers. But thankfully we’ve Sunshine, an app that can achieve S-OFF on a number of HTC devices, it’s co-developed by jcase & beaups.

Sunshine isn’t a free service though, for the hard work developers does to make it possible to S-OFF even the shiniest of devices from HTC using Sunshine, the app charges you a fair amount of $25 to be able to use it..

The Sunshine app works pretty easy: you install the app, pass through the disclaimer, perform a compatibility check, pay for the service ($25), and then finally S-OFF the device. It’s a smooth process.
