Any doubts on tacoroot method, pm me...
Hit thanks if I helped You...
I have Sensation with S-ON and HBOOT 1.27.0000
First problem I have met, that HTCDev does not work on my device (and on others with latest stock rom), can't flash in fastboot (i.e. recovery) therefore I can't root and can't S-OFF.
Jonouputbear and Tacoroot did not work.
Any real solution?
You just need to keep trying cause many others have posted that they had trouble getting the HTC Dev unlock to work, but they did eventually get it to work. The HTC Dev unlock does work with the 1.27.000 Hboot version. If it did not the Juopunubear S-off would not hsve even been developed.
