HOW TO DISABLE THE SMS TO MMS AUTO, UNLIMIT-CONVERSION WHILE EXCEED 3 SMS

WHAT DOES THIS MOD DO: This mod will let you type very long text messages and it won't automatically convert it into MMS.

★ Go into your system/priv-app/SecMms_Delight_Open folder and take out your "SecMms_Delight_Open.apk"

★ Then use one of the applications such as apktools or baksmali and then use the commands to decompile the SecMms_Delight_Open.apk

★ Once you have decompiled the SecMms_Delight_Open.apk, go to:

Now open up "l.smali" with your notepad++ for editing.

Now for this part of this guide what I have highlighted in "GREEN" text is what you have to find using Notepad++, What you see in "RED" is the line you have to remove/delete completely, And also what you see in "BLUE" is the line you have to make changes to:

SEARCH FOR:

[COLOR="Green"] sput v0, Lcom/android/mms/l;->Q:I[/COLOR]

[IMG="Mod SecMms_Delight_Open Galaxy S6"]http://choimobile.vn/attachments/1-jpg.18356/[/IMG]​

NOW REMOVE:

.line 213
[COLOR="Red"] const/4 v0, 0x4[/COLOR]

[COLOR="Green"] sput v0, Lcom/android/mms/l;->Q:I[/COLOR]

AND CHANGE TO:

.line 213
[COLOR="Blue"] const/16 v0, 0x3e8[/COLOR]

[COLOR="Green"] sput v0, Lcom/android/mms/l;->Q:I[/COLOR]

NOW SEARCH FOR:

[COLOR="Green"] sget v0, Lcom/android/mms/l;->Q:I[/COLOR]

[IMG="Fix mms s6"]http://choimobile.vn/attachments/2-jpg.18357/[/IMG]​

AND REMOVE:

.method public static e()I
.locals 1

.prologue
.line 881
[COLOR="Red"] sget v0, Lcom/android/mms/l;->Q:I[/COLOR]

return v0
.end method

AND CHANGE TO:

.method public static e()I
.locals 1

.prologue
.line 881
[COLOR="Blue"] const/16 v0, 0x3e8[/COLOR]

return v0
.end method

NOW SEARCH FOR:

[COLOR="Green"] sput v1, Lcom/android/mms/l;->Q:[/COLOR]I

ABOVE THIS SAME LINE YOU HAVE TO ADD A NEW LINE WHICH IS IN BLUE:

.line 2481
const-string/jumbo v1, "pref_key_threshold"

const/4 v2, 0x4

invoke-interface {v0, v1, v2}, Landroid/content/SharedPreferences;->getInt(Ljava/lang/String;I)I

move-result v1

[COLOR="Blue"] const/16 v1, 0x3e8[/COLOR]

[COLOR="green"] sput v1, Lcom/android/mms/l;->Q:I[/COLOR]

Once done now save changes, Recompile your SecMms_Delight_Open.apk and that's it you are now DONE!!!

HOW TO CHANGE THE MESSAGING TIME STAMPS TO ITS ORIGINAL TIME

WHAT DOES THIS MOD DO: This mod will show the exact sent time of received messages, not the moment when you actually received it on your phone.

★ Go into your system/priv-app/SecMms_Delight_Open folder and take out your "SecMms_Delight_Open.apk"

★ Then use one of the applications such as apktools or baksmali and then use the commands to decompile the SecMms_Delight_Open.apk

★ Once you have decompiled the SecMms_Delight_Open.apk, go to:

Now open up "SmsReceiverService.smali" with your notepad++ for editing.

Now for this part of this guide what I have highlighted in "GREEN" text is what you have to find using Notepad++, What you see in "RED" is the line you have to remove/delete completely, And also what you see in "BLUE" is the line you have to make changes to:

SEARCH FOR:

[COLOR="Green"] invoke-static {}, Ljava/lang/System;->currentTimeMillis()J[/COLOR]

THIS SAME LINE THAT YOU HAVE JUST LOOKED FOR, IS ALSO THE LINE YOUR GOING TO HAVE TO REMOVE WHICH SHOULD LOOK LIKE THIS:

.line 2668
:cond_8
const-string/jumbo v2, "date"

[COLOR="Red"] invoke-static {}, Ljava/lang/System;->currentTimeMillis()J[/COLOR]

move-result-wide v4

invoke-static {v4, v5}, Ljava/lang/Long;->valueOf(J)Ljava/lang/Long;

move-result-object v3

invoke-virtual {v1, v2, v3}, Landroid/content/ContentValues;->put(Ljava/lang/String;Ljava/lang/Long;)V

goto/16 :goto_1
.end method

​

AND THEN CHANGE IT TO THIS:

.line 2668
:cond_8
const-string/jumbo v2, "date"

[COLOR="Blue"] invoke-virtual {p1}, Landroid/telephony/SmsMessage;->getTimestampMillis()J[/COLOR]

move-result-wide v4

invoke-static {v4, v5}, Ljava/lang/Long;->valueOf(J)Ljava/lang/Long;

move-result-object v3

invoke-virtual {v1, v2, v3}, Landroid/content/ContentValues;->put(Ljava/lang/String;Ljava/lang/Long;)V

goto/16 :goto_1
.end method

Once done now save changes, Recompile your SecMms_Delight_Open.apk and that's it you are now DONE!!!

Comming soon...
