HELP!! PHONE get STUCK with RED triangle

[Guest xlxlxl]

Hi, aber i rebrant my T-mobile Desire and flashed this one Desire_HTC_WWE_1.21.40_NoRadio_NoHBoot_Rooted_Sign ed.zip, everything was fine. But i still havn't root, today i tried to in the recovery Mod again and used TinyCoreLinux

in there i typed

sudo mkdir /mnt/cdrom

sudo mount /dev/cdrom /mnt/cdrom

cd /mnt/cdrom/root

sudo ./step2.sh

and get stuck since 30min with the Red Triangle!!

What should i do?? Can i just put out the batterie?:confused:

to leave the triangle-screen:

-press Volume up ("+") and the power-button.

-select "Reboot system now"

..and you're done! :(

no battery removal necessary
