I have a samsung galaxy ace 2.3.6 (the original firmware from samsung), it is rooted. And I want to install a custom ROM, so I need to install Clockwork mod first. So I installed clockwork mod 4, and after installing it, when I was already rebooting it, It gets stucked at the start up screen showing my phone model. I do not know what went wrong, i followed the steps mentioned in the threads i found: 1. Download the file, ClockWorkModAce.zip 2. Copy the downloaded file, ClockWorkModAce, to (the root-directory of) your sd-card. 3. Power off your phone (using power button). 4. Boot up your galaxy ace to recovery mode (Press Home + Power Button). 5. Select Update Zip From SD-Card option. 6. Choose the file (named : ClockWorkModAce.zip) you downloaded earlier. (Note :- Use Home button to select). 7. After it finishes installing the zip file, reboot your device. --now after installing it, I cant open my phone anymore. (((( PLEASE HELP!!! i dont know what to do, im screwed.
