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:-
CDMA (Verizon HTC One)
