[SIZE=+1]Q1: Why isn't Flashtool working?[/SIZE]

If you are getting an error message about the header of your ftf, then you will need to copy loader.sin into your ftf file before flashing. Make sure that the drivers for your device are loaded and that you wait for Flashtool to ask you to connect your device. Your device should be in msc mode and USB debugging needs to be on. There is a thread dedicated to issues with flashing here.​

[SIZE=+1]Q2: How do I root my device?[/SIZE]

Rooting is usually done by applying an exploit or sometimes it can be done with Flashtool. Rooting can be a little bit confusing because not every version of Firmware is vulnerable to the same exploits, so some rooting strategies require changing the Firmware as part of the rooting process. It is probably best to consult one of the rooting guides for your device. For example: here or here​

[SIZE=+1]Q3: How do I unlock the bootloader?[/SIZE]

Unlocking the bootloader is essential if you want to use custom kernels. After unlocking the bootloader you will have to use Flashtool to update your device because PC Companion and SUS won't recognize your device, unless you relock your bootloader. You can use either the Official Sony Unlocking method or SE Tool to unlock your bootloader. See the guide here​

[SIZE=+1]Q4: Will --fill in the blank-- work on the Dual?[/SIZE]

If it doesn't explicity say that it works on the Dual, it probably doesn't. Make sure to read the OP carefully and have a recovery strategy in place, for example a recent nandroid back up, just in case.​

[SIZE=+1]Q5: What is the best ROM or kernel?[/SIZE]

This is probably NOT a good question to be asking. Asking this question will most likely get you made fun of, and since it is against the rules, your thread or post will most likely be deleted. The best ROM or kernel will depend on how you use your device and what you are hoping to get out of it. So, only you can answer this question, have a little bit of fun testing different ROMs and kernels and then pick the set up that works the best for you.​

[SIZE=+1]Q6: Where is everybody? Why am I so alone?[/SIZE]

lol, don't worry, sometimes it takes a little bit of time before Development of a device takes off. It is already clear that this is going to be a vibrant place for Development.​

[SIZE=+1]Q7: Where can I get more information? What if I don't see my question here?[/SIZE]

The search functions in xda are pretty powerful and they will help you find what you are looking for. They can usually be found at the top of all the forums and the "Search this Forum" box usually does a good job narrowing your search down. There is a good index/all-in-one guide in the Development section: here and a "Help for any topic" thread here Make use of them!​
