A few days ago we reported that HTC One on hboot 1.54 had been s-off’ed. Well the s-off has now been released and is called rumrunner. Please note this method will install stock unsecure kernel (by stock we mean Sense based kernel) so if you are on a custom rom it will result in a bootloop.

It has been reported working on below firmware versions:-

GSM

2.24.401.1

1.29.707.4

2.24.401.8

2.24.401.9

2.24.709.1

2.24.161.1

CDMA (Verizon HTC One)

1.10.605.2

1.10.605.8

1.10.605.10
