I would be really grateful if someone could test these blobs in terms of fixing data without any hacky scripts:
Thanks.
I made a complete backup, pushed the files using adb from the CWM recovery.
If anyone is interested, mount /system in CWM, on the computer then,
adb devices,
adb shell ls -l /system/bin/ (in order to list the files and permissions,
adb push ks /system/bin/,
adb push netmgrd /system/bin/, ls again (my permissions where kept).
Then
adb shell ls -l /system/lib/libac*,
adb shell ls -l /system/lib/libcs*,
adb shell ls -l /system/lib/libnetm*
adb push libacdbloader.so /system/lib/,
adb push libcsd-client.so /system/lib/,
adb push libnetmgr.so /system/lib/,
then all 3 ls again to check the permissions, also kept during the push for me. End with
adb shell reboot.
It boots, but nothing changed, no Data at all, and running the script still solves the issue.
I will remain with the files for now and see if it has changed anything else but probably not.
We'll find it one day.
