Have you tried using your bootloader to do a factory reset? I don't know how to do it on a Dell phone, but try:

Pull the battery, let it sit for 10 seconds, put the battery back in. (if you can't remove the battery, do a full shutdown)

Now hold your volume down button and push the power button.

Depending on how Dell did it, you may have an android icon in the middle of a warning triangle. Push power, volume up, down, or other buttons (and even combos) until you get text. Or search for how to access reset through your bootloader on google. Now you should be able to reset the default using the bootloader. This should restore you to 100% stock.

Also, search XDA for any recovery files, an SBF, or something that can reflash your phone.

i tried doing a hard reset to the phone by pressing the volume down + power key at the same time but nothing happens. i think i corrupted the privileges... so that no one is able to use them..

Are you able to do the temp root option again? If so, temp root then reboot. Then try Z4 for perm root again. If that fails, but you're able to do temp root: Temp root, install ROM Manager and have it install clockwork mod. Then reboot into recovery using something like "Quick Reboot" from the market to go directly into clockwork mod. From here you can delete everything on /data (wipe cache partition and dalvik cache, as well) and flash a new ROM. Get a ROM from XDA's Dell xcd35 section. You can put it on your SD card by going to Advanced and enabling USB drivers (or whatever it's called). Transfer files over and then flash it by 'installing zip from SD card'.

Im able to temp root and i also checked if i can run su on the command prompt "yes i can" when i reboot my phone i cant run su because its just temp root. sounds perfect!

Now i try factory data reset... doesn't work...

but when i perm root my phone after rebooting im unable to run su i get permission issues

does this mean ibroke the software seal and the data reset wont work any more??

Ok, so temp root then install ROM Manager. Now, after giving it SU permissions, you should be able to install Clockwork Recovery, right? If so, good. Now download "Quick Reboot" from the market, click recovery, and give it SU permission to reboot into recovery. Anything happen?
