ok, I don't know why no one is replying to me neither you krarvind... but I'm getting really frustrated with this.
Using apktool, I decompiled mms.apk (yes, I installed the framework from my system/framework)
I modified mms_config.xml (from res/xml). I just changed two values:
-20 recipients limit to 100
-8 sms to mms treshold to 200
Then, compiled again. Then, deleted resources.arsc from the compiled apk.
Finally, copied META and resources.arsc from original mms.apk to the one I compiled.
I copied that to system/app using root explorer and set permissions to rw-r--r--
Rebooted and nothing. The messaging apk wouldn't even show up in launcher! Please someone help me cause I've spent lots of hours on this and still nothing....
Below in attachments is my final mms.apk that doesn't work.. in case someone wants to check it for errors
