I read thru the first few posts again.
If you are talking about the tutorial which is this :
TUTORIAL 5: Recover System Apps than have been removed from V3
-- Place your desired app or apps on your sd-card
-- Use Root Explorer and copy them
-- Go to system\app and press the Mount R/W button on right top
-- Paste the app or apps you have selected
-- Long press what have you just pasted and set permissions to rw-r--r-- for each app
-- Reboot phone
Yes, i followed this. Was able to recover apps like camera. But sounds recording doesn't work.
If i misses out something, can you help me with pointing me to the particular fix for it ? I've done searching, and no people seems to be asking about sound recorder.
