I have been searching a way to replace system app with other app. I successfully replaced my music app in cyanogenmod 7.2 with a miui music app through root explorer but when I tried to do same with the message app nothing happens and the message app disappears from the app drawer.
Please tell me a way to replace it
1) by root explorer.
2) by flashing a zip of that app.
I have a link where a tutorial on replacing a system message app is given but it is for custom rom
Can you also tell me is it possible to make a flashable zip of any .apk file.
I really need to do this thing as in default mms.apk there is no option to select recipients from contacts. Every time sending the message I have to write a name each and every person which is frustrating. Please guys help me.
