Freeze via Titanium Backup: FWUpgrade.apk and SDM.apk
Use Root Browser or Root File Manager to:
Rename file: /etc/security/otacerts.zip to otacerts.zip.bak
Rename file: /system/app/ wssyncmlnps.apk to wssyncmlnps.apk.bak
Then do the following:
1. Open Root Browser or Root File Manager
2. Navigate to data/fota
3. Long Press and select Permissions
4. Uncheck all boxes making it 0000
The last bit is overkill, but you can do it if the OCD kicks in.
Just Say No to root-killing updates
Thanks Joe! If I freeze the 2 .apk files you mention with Titanium Backup, then do I still need to do the other stuff with root browser? (I use ES File Explorer, which I assume should also locate those directories and files.) So far, I've just been telling the nightly "upgrade" reminders to go away for another day.
