hi guys, new desire owner here..just bought about 1 month ago..hehe
wanna ask you guys about rooting..
i have a desire SLCD set, with PVT4..stock 2.2 froyo.
tried to root with latest unrevoked3..at first everything is okay (got say this is huge triumph msg)..then reboot..took too long..(more than 20 minutes)..so i reboot from phone itself..no problem..but of course the root was considered unsuccessful,(no superuser app,etc2)..
So decided to rerun unrevoked3 and start over..
but now everytime i run all okay until it got msg says
Error:failed to get root.is your firmware to new?
help

Check your HBOOT version. Ideally it should be 0.93 or an older version.
