it could be in userapp partition… you can check ati3 and ati8 to make sure FW has been changed. ---

Just have a try with R13.3 and WP7609: 1. modify /etc/init.d/startlegato.sh 2. run WP76xx\_Release13.3\_GENERIC\_GCF.exe 3. the startlegato.sh will remain unchanged with the modification 4. mv /mnt/flash/ufs/etc/init.d/startlegato.sh /mnt/flash/ufs/etc/init.d/startlegato.sh.test 5. run WP76xx\_Release13.3\_GENERIC\_GCF.exe 6. the startlegato.sh will be back to the default one so you are correct!
