Problems with a mobile application help!

Question

im having difficulty getting this game to work. its a simple black jack game. what ive done is generated a random number, then if its this number put this image on the screen, if its this number put that image on the screen, etc etc etc. only problem is nothing happens when the program runs. itll start, the music will play and all that will work. but it wont show any images when buttons are clicked. I dont know whether its something wrong with the drawing sprite images, or the buttons not actually responding. can anyone see why its not working? any help would be greatly appreciated. here is the code

Answer 1

first of all try update the firmware if that dont work try the following
cred for rad 24
With all these operations I recommend you TAKE OUT MEMORY CARD and DO A BACK UP OF YOUR STUFF!!!
NOTE: In front of the hash key ( #) there is also a STAR key that people often miss and state that the code does not work.
1.. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data) Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for ALL operations listed here is 12345.
2.*#7370# - Reformat your phone (out of the box, tho keep in mind that most newer nokia phones at least n series, e series and s60 based phones have udp - user data preservation so not ALL data may be lost. still it is a good idea to always do a back up of your stuff.)3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
3. hard reset - hold the following buttons * (star key), 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM - use the following buttons to do a hard reset, /GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800's that have firmware version 20... and up. ) For Nokia N97 (unofficial version but works) is SHIFT /SPACE BAR / BACKSPACE while holding the power button. Again do not let go until you see the handshake screen.
If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.
If  i have helped at all a click on the white star below would be nice thanks.
