This mod will make you able to have torch flash light while you are on LockScreen by long pressing on the home button...!!!
Actual mod was done by RobbieHood and eybee1970
Needed tools:
1) Backsmali/Smali program from here
2) Notepad++ program from here
3) WinRAR or 7-zip archiver
The procedure:
- Backsmali android.policy.jar
- Navigate to classout/com/android/internal/policy/impl/ folder
- We will be working on 3 smali files:
KeyguardViewMediator$4.smali
- Search for "packed-switch" and add the blue line just above "return-void":
- Search for ":catchall" and add these lines above it:
- Now go to the end of smali and add these switches above ".end packed-switch" line:
Code:
.line 1255
iget v2, p1, Landroid/os/Message;->what:I
packed-switch v2, :pswitch_data_72
.line 1298
:goto_7
[B][COLOR="Blue"]:pswitch_7[/COLOR][/B]
return-void
.line 1257
Code:
.line 1295
monitor-exit v1
goto :goto_[B][COLOR="Red"]7[/COLOR][/B]
[B][COLOR="Blue"] :pswitch_6e
iget-object v2, p0, Lcom/android/internal/policy/impl/KeyguardViewMediator$4;->this$0:Lcom/android/internal/policy/impl/KeyguardViewMediator;
iget v3, p1, Landroid/os/Message;->arg1:I
if-eqz v3, :cond_majdi
move v3, v0
:goto_nj
#calls: Lcom/android/internal/policy/impl/KeyguardViewMediator;->handleSetTorch(Z)V
invoke-static {v2, v3}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->access$2400(Lcom/android/internal/policy/impl/KeyguardViewMediator;Z)V
goto :goto_[COLOR="Red"]7[/COLOR]
:cond_majdi
move v3, v1
goto :goto_nj[/COLOR][/B]
:catchall_7b
move-exception v0
monitor-exit v1
- Search for "nop" and another "nop" line bellow it (don't forget to leave empty line in between):N.B: pay attention to number 7 in goto :goto_7 that could be different in your smali according to your ROM, make sure it is the same as the first one which is just above the new line ":pswitch_6e"
Code:
.line 1255
nop
[B][COLOR="Blue"]nop[/COLOR][/B]
Code:
:pswitch_data_72
.packed-switch 0x1
:pswitch_8
:pswitch_10
:pswitch_16
:pswitch_1c
:pswitch_22
:pswitch_28
:pswitch_2e
:pswitch_38
:pswitch_40
:pswitch_4c
:pswitch_52
:pswitch_58
:pswitch_64
[B][COLOR="Blue"]:pswitch_7
:pswitch_7
:pswitch_7
:pswitch_7
:pswitch_7
:pswitch_7
:pswitch_6e[/COLOR][/B]
.end packed-switch
.end method
Save changes...N.B: if your smali has :pswitch_7 and :pswitch_6e by default, then use another :pswitch_value for :pswitch_7 and :pswitch_6e. If you do so, then don't forget to change :pswitch_7 and :pswitch_6e value in added codes from the beginning above as well
KeyguardViewMediator.smali
- Search for ".field private static final SET_HIDDEN:I = 0xc" and add this line bellow it (the blue one):

PhoneWindowManager.smali
All changes here, will be in this method ".method public interceptKeyBeforeDispatching(Landroid/view/WindowManagerPolicy$WindowState;Landroid/view/KeyEvent;I)J"; so it is better to know from which part of smali this method starts and ends in order to not touch other methods!!
- First search for the method ".method public interceptKeyBeforeDispatching(Landroid/view/WindowManagerPolicy$WindowState;Landroid/view/KeyEvent;I)J",
- Search for "Lcom/android/internal/policy/impl/PhoneWindowManager;->mHomePressed:Z" and add these lines bellow it (the blue ones):

Now backsmali classsout folder to get new classes.dex file. Now Open android.policy.jar by WinRAR or 7-zip and drag and drop the new classes.dex file inside it; then push it to your device framework folder and fix permissions to chmod 644.
Download Torch.apk from attachment bellow and push it to your device app folder and fix permissions to chmod 644 as well... and viola.. lockscreen the device and do long pressing on home button to have torch flash light..:laugh:
If you could manage to shorten this tutorial by omitting unnecessary steps, then share your experience here please
