You probably did not make the Res folder in your Phone memory that's why you are facing this problem..
Just do the following:
==> Download this: http://www.megaupload.com/?d=5K6H2GK3
==> Inside that pack you will get an app_patch.bin and an rc2 file..
==> Use that apps_patch.bin.. you can use the android rc2 that you downloaded earlier or the new rc2 which you downloaded in the above mentioned pack.
==> Now in the multiloader select LSI6410 and provide the libk of rc2 and apps_patch.bin wherever it is required and then press the download button
** Now your boot screen will change. This is what you have noticed right? Here are the next steps.
Now you download any theme. You can find the themes here: http://darkforestgroup.com/starmod/index.php?board=4.0
You will notice that inside the theme you have some files like gadget.swf, menu.swf, myfiles.swf
==> Now go to your phone memory and make a folder "Res" there.. Inside the Res folder, place the gadget.swf,myfiles.swf,menu.swf.. Or as a starter place everything that you downloaded from the theme section into the Res folder..
==>Now after doing the above mentioned steps, switch off your mobile. Now switch it on and while you are getting the new boot screen press and hold the lock key for 2 seconds.
==> you will be redirected to a patch menu.
==> Now in this patch menu, up/down navigation is done with volume up/down keys, selection is done using camera key and saving is done using lock key.
==> Here you will get 4 options as
1. Patch Menu
4. Restart Phone
==> GoTo patch menu by pressing camera key.. then you willl get a list of patches. Among those patches activate change swfv1 patch. (activation means moving to change swf v1 by moving up/down using volume keys and then selecting it using camera key) After you select it, save them using the lock key again. then you will get 'Saved' written at bottom of screen.
==> Now press the back button and again you will be back to the menu with the four options as shown above.
==> Now select Restart phone and your phone will restart..
==> Let the phone boot normally and then you will get a new for your phone..
==> Try it and let me know wherever you are stuck..!!
