I did not make UnrEVOked, I just make the guide
It enables you to root easily & have a custom recovery image installed (like Hero or G1) so that you can have access to Recovery anywhere. (& Backup SD EXT)
Can I get Back?
You can get back very easily by using an HTC RUU for your network which you can find here. Or use one of my OpenRUUs for Linux & Mac users.
A HTC Desire
A PC, Mac or Linux (Linux or Mac recommended because you will have no problems with drivers or HTC Sync.)
NOTE: When UnrEVOked 3.2x is released, This method WILL work with it.
You can check UnrEVOked's Twitter feed to check if it has been released yet or join #unrevokedtest IRC here to see if there are any test builds avalible.
(FYI, 3.2 roots FroYo)
Follow my guide here to root & flash a recovery image! http://bit.ly/c53S7A
(the guide is on my site so I can edit it easily and to prevent all the copies becoming out of date.)
