I accidentily deleted mms.apk (missclick, stupid, I know) and I tried restoring it to a version I found online. What I did was copy it to my SD card, in root explorer mount to r/w, moved the file to system/app/ and tried to install it there.
Those were the instructions I found. However, I got the message 'application not installed'.
What could be causing this, am I trying to install the wrong mms.apk? If so, does anyone have the proper one for the LG Optimus 2x?
Thanks in advance!
