[Q] Official unlock with firmware version 2.42.405.4
I am trying to unlock (s-off?) my desire z with official procedure at htcdev.com site.
Unfortunately I had an ota upgrade to 2.4.405.4 (perhaps bug fixing...)
Obviously OFFICIAL htc software does not recognize 2.4.405.4 version.....
well there is no need to back anything up but if you really want to, fully read the guide and it will show you how to temp root you phone and then use titanium to back things up. personally I feel this is unnecessary but do as you'd like
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
