Is there any risks of flashing the phone? Can it be permanently bricked or spoiled if the flashing goes wrong?

Flashing is not risky if uve got CID36 or CID 49 and NOT brown phones but you gotta follow all steps with pateince.Read all tutorials and understand before u get down to flash

If I flash my phone and change the system files, does my phone's warranty get void?

It does get void . but if u reflash back to k750 using tutorial 3 then ur warranty stands again ( since the sony guys wont know that uve flashed!!even if u fiddle with acoustcis, or camera, thers no way SE ppl can detect any changes. they just dont have the facilities to do it.

Camera Sounds - Silence

Method 1: Disable Camera Sound completelyThe camera sounds come from the files camerashutter.3gp and camerafocus.3gp. If these files don't exist, the camera is silenced. This means the camera makes no sound even if the phone is not in Silent Mode. You could also delete only camerafocus.3gp for example, if you only want the shutter sound to be heard.The camera sound files can be deleted from /tpa/preset/system/sound

Method 2: Enable Silent Mode for camera soundsThis method will enable you to disable the camera sounds by turning on Silent Mode. When not in silent mode, camera sounds will operate as normal.Copy the customize.xml file in /tpa/preset/custom to the computer and make a backup. Open customize.xml in an editor and change the following setting from false to true:trueSave the file then delete the existing customize.xml on the phone and copy in the new version.Important: You will have to do either a settings or master reset before this trick will take effect. Once you do, you will be able to silence the camera on demand, simply by putting the phone into silent mode

Backup Games and Java Apps

All Java midlets can be backed up by copying the jar and jad files from the phone to your computer.The jar and jad files at can be found here: /tpa/preset/system/ams To backup your games, simply copy the jar and jad files in this folder to your computer.The games will need to be reinstalled if you delete them from the phone and then later want to reinstall. You can't just copy the old files back into the ams folder. But you can use the old jar and jad files you copied from the phone to reinstall the game (the same way you would install a game normally)

Deleting Pre-Installed Content and Games

You cannot delete the pre-installed content from the handset itself, but with access to the internal file system you can delete ANY pre-installed content you want. Simply browse to the folder where the preset content is stored and delete it.Here are the folder locations for the various pre-installed content:

Games: /tpa/preset/system/ams.

Games: /tpa/preset/default/java

Sounds: /tpa/user/audio

Sounds: /tpa/preset/default/audio

Images: /tpa/user/image

Images: /tpa/preset/default/image

Themes: /tpa/user/theme

Themes: /tpa/preset/default/theme

Video: /tpa/user/video

Frames: /tpa/preset/system/multimedia/pe/frames

Frames: /tpa/preset/system/multimedia/pe/funlayer

Clipart: /tpa/preset/system/multimedia/pe/clipart

Change System sounds

The various system sounds are stored at /tpa/preset/system/sound. If you replace them with your own versions you can change the sound the phone makes for a given system sound. For example you can replace the noisy lowbattery.mid with something more subtle.Replacement sounds should have the same name and audio format (mid, mp3, amr) as the original, and be about the same length.To replace a system sound, delete the existing sound from /tpa/preset/system/sound and copy in your own version.

Change Startup and Shutdown sounds and Images

Startup and shutdown images and sounds are located in various locations. To change, simple delete the existing file, and copy in your file with the same name. Here are the various names, file sizes, formats and locations:Boot image: SPLASH in /tpa/preset/system/settings/This is the 176x220 pixel image displayed at boot up, called the Splash Screen. Can be in gif, bmp or png format. Animation not supported.Startup Image: STARTUP_IMAGE_SEMC in /tpa/preset/system/settings/This is the 176x220 pixel image shown after the Splash screen. This image can be chosen by the user in settings/display/start-up screen so you don�t need internal file system access to change this image.Shutdown Image: SHUTDOWN_IMAGE_SEMC in /tpa/preset/system/settings/This is the 176x220 pixel image that is shown when the phone is shutting down. Can be in gif, bmp or png format. Animation is supported, but total number of frames should be kept low, and gif should not be set to repeat animation, as this will slow down the shutdown.Startup Sound: STARTUP_SOUND_SEMC.mid or STARTUP_SOUND_SEMC.mp3 in /tpa/preset/system/settings/This is the sound that plays when the phone starts up.Shutdown Sound: SHUTDOWN_SOUND_SEMC.mid or SHUTDOWN_SOUND_SEMC.mp3 in /tpa/preset/system/settings/This is the sound that plays when the phone is shutting down.

Delete the SE Web links

Sony Ericsson or your operator install links at the top of every folder in your phone's file system to websites with their content. These are pretty useless to most of us, and serve only to clutter up access to our files. The links are stored in two locations within the file system.Firstly, as xml files in folders within fs/tpa/preset/system/custmenu. For example the folder GAMES_HOOK_1 might contain an xml file pointing to the operator's game download page, as well as an image used as the icon.Secondly, the links are cached in the files cust_menu_data.dat and cust_menu_done_unpacking.dat that sit in fs/tpa/preset/system/custmenu.To get rid of an operator link, you need to delete the folder in custmenu for the relevant link, then delete the files cust_menu_data.dat and cust_menu_done_unpacking.dat.

Get rid of tiresome cam sound...

The camera sounds depend on the files camerashutter.3gp and camerafocus.3gp. You can change the camera sounds by replacing these files with your own versions. The new sound files must have the same names as the old ones, and be in 3gp format, preferably audio only.Delete the existing files from fs/tpa/preset/system/sound and then copy in the new versions.

TO INCREASE SMS STORAGE…

To increase the everlasting SMS inbox storage memory....

These are the prime requisites to increase SMS storage----

1.USB flash Drivers
2.XS++
3.FAR manager with SEFP

Lets start…

1) [only for CID49]::Firstly, we need to patch our MAIN firmware to make it compatible with FAR and SEFP. For this remove SIM and connect your phone with XS++ [as we do in flashing,with the 'c' key pressed](or any other flashing program that you use), and check to -"Flash MAIN Firmware". Click ‘…’[path] and browse to the FAR folder and then to Plugins folder. Select the file according to your phone model, in my case, ‘k750w800_r2e_dcu.49r.ssw’ (for K750/W800/W700 CID49) . Now hit flash . 5 flashblocks will be loaded in 5 seconds!!!). Now our MAIN is patched.


2) [for CID36 and CID49 both]::Close XS++, unplug fone and re-insert battery to refresh. Now open FAR manager program. Press F11 and then select SEFP plugin. in the following screen select… Device:DCU60, Speed: 921600 ,Boot Script: According to fone model (k750_w800_CID49 or k750_w800_CID36) Do it carefully!!! … Now Hit --Enter The MATRIX!!!Connect your fone when asked with the "c"button pressed,,after detection release "c" button.after a few seconds, a screen will show you two folders, FLASH and FS. Note that the window is divided into two… the left side represents your phone contents. The right side represents your PC's hard drive contents… currently inside FAR manager folder.

3) [for CID36 and CID49 both]::Now double click on FS and wait for a couple of minutes till it breaks into your FileSytem. Now you are inside the phone's control centre. Before we do something u must create a backup folder for your original files (in case you need them). So on the right side (harddrive) of your screen, click anywhere and press F7 to create a new folder. Name it as ‘backup’. On the left side (fone FS) open the folder,/ifs/settings/messaging… you will see a file named pref_store.txt. Click and drag this file to the backup folder. now,select it and press F4 to edit the file. in the new screen, change '/smsdata' to '/tpa'. press F2 to save and F10 to quit the file editing.Now goto the root directory by clickin "..." where u see ur ifs,tpa,system,etc etc folders... there is a folder called smsdata with 2 folders inside --messaging and system. copy both folders of smsdata to tpa folder. this way your old sms wil not be deleted.

4) [for CID36 and CID49 both]::Now, that we are finished with our operations, we need to shutdown the loader. For this keep on clicking ‘..’ (root of folder) until it asks you to shutdown CSFS loader.Click yes and Quit FAR manager, and unplug fone. Remove and Reinsert battery to refresh.

5) [only for CID49]::The final step is to un-patch the MAIN firmware. Again, open FAR manager program, and connect fone, the same way as before. This time goto FLASH instead of FS. and now in FAR manager folder. goto Plugins folder and then to REST. You see a number of files… with prefix ‘REST_’ followed by your fone’s firmware version. Select the appropriate file of your MAIN firmware (I have a k750 flashed to w800 r1bc002 main so REST_W800_R1BC002 in my case) and drag it to anywhere on the left side. select Copy then in the new window Hit flash. Quit FAR manager and unplug your fone. The job is done!!!

Insert SIM and turn on your fone and enjoy.........
