Ok, firstly, just be careful if you attempt this, as I
cannot be held responsible for any damage or corruption caused to your phone.
You are doing this at your own sole risk. I have experience with modding phones and it is probably a lot easier for me to write up than it is for you to understand. If you have a concern or are confused about something, do
NOT proceed with the operation. Just take it slow and research the appropriate method for applying each item. Ask here for help if necessary, and I'll do my best.
The basic tools you're gonna need to flash your phone are:
1) Your phone (nah...)
2) A computer running a recent version of XS++
3) The data cable that came with your phone
It's probably not a good idea to start off with the patching, as that can get a little confusing, but it's fine to start off with a simple camera mod. Speaking loosely, you're gonna need to find a camera driver for your phone that you like the look of (just google them, they're easy enough to find). If you don't like one don't worry, just download another and keep re-flashing until you find one you like. You then need to connect your phone to XS++, navigate to 'FSX', and then flash the camera driver to
IFS/SETTINGS/CAMERA
Then just re-insert the battery, boot the phone, go to the camera option, and you should find yourself using the new drivers. Simple

.
The same method applies to the audio drivers - just find the ones you want to use, go to FSX, and then apply them to
IFS/SETTINGS/ACOUSTIC
Start your phone and enjoy

. I won't name all the directories, as that'll take ages, but those are a couple of basic ones. If you find someting you want to change, just get the driver / patch you need, and google the location it needs to be set. Have fun
