Root superuser denied

[Chinese guy]

Hi,guys, I am a Chinese.

I got a Desire Z recently, and wanna flash the rom.

I followed the procedure, downgraded the system to ver 1.34,get temprooted,and perhaps permrooted.(I can access the "root" directory every time I restart my phone in the file explorer)

I linked the phone to the PC,(Charge only,and USB debugging checked) and run adb, but cant get SU permission.

It's so too, in the Terminal Emulator,

I also installed a program on my phone called "superuser permissions", run it, just black screen.

Why? Anyone can explain. Thanks.

Welcome to Android Forums!

Whenever you run an app that requests root, SU Permissions should display a pop-up to allow you to confirm it. Similarly, at a Windows command prompt

c:>adb shell
$
su

should cause the same request to appear on the handset. What error(s) do you see when you try this?
