As Frodo suggests you may be better going to the Crescent section in the Modoco Forum. You`ll be able to join the Darkside and hopefully sort it then
You basically need to install the Clockwork Mod so that you can get into the CWM Restore screen. In there you use the up/down Volume buttons to move through the selections and the last selection is Advanced, that moves you to the second page with the HOME key being used to select. The back key takes you back to the first page. Wipe Data/Factory Reset and other options are in there. If installing a new ROM it needs to be on the SD card ready. If its the Crescent.zip (use for Vivacity or SFII) then you need the Vivacitykernel.zip (use it to make sure all keys are aligned, for SFII users theirs also a SFIIkernel.zip file) on the SD card too. You need to Flash both one after each other before choosing the option to restart the system (phone restart). This takes up to about 10 mins to restart the phone as all the changes are applied. Its advisable, if you proceed, to wipe the Cache and the Dalvik Cache as well as the Data/Factory Reset. Then you have a better chance of a fresh start.
This does not unlock the phone, that`s a separate routine and needs to be done before applying this ROM change, if that`s what you intend to do. Basically it`s apply the drivers with the USB lead disconnected, install QPST on the PC, turn on USB Debugging on the phone, press and hold the VOL down button on the phone and start it-release the button when you see FTM on the screen. Reconnect the USB lead then open the correct USB Port in QPST Configuration. Once done and showing the phone is connected close QPST and open Software Download. Save a QCN Backup file, unzip the correct unlock folder (Vivacity or SFII) and run download. Press START then sit and wait. Restore the QCN Backup. Remove the battery and USB Cable then insert your Sim card of choice, sorted! Full instructions are there, this is the condensed version to give you an idea.
