Re: Instant Re-Imaging Tablets in EDU environment
Not sure if this is relevant anymore, but I was not able to find one...I did however find a reasonably decent way of clearing the tablets between students though by clearing app settings for downloads, browser and whatever else and then removing the files in the directories that typically have files saved in them all over ADB.
You can make a batch script that goes tablet by tablet. Install the android SDK and get ADB running, not helping you there... but once it is.
ADB Devices will list all of the attached devices, enable developer options and authorize the tablets. You'll also have a list of what tablets are attached and the device ID(DevID) something like e233ge21. You'll need to figure out what apps your allowing to run, and the actual app name to clear its settings out. Get one tablet running and you can copy and paste it so the script clears the other tablets in the same way.
The lines with the rm command delete the files in the directory
the lines with the pm command clear the app settings to those apps. The downloads and gallery3d settings are important because deleting the pictures and downloads directories leaves traces behind of empty files.
adb.exe -s DevID shell rm /mnt/sdcard/Download/*.*
adb.exe -s DevID shell rm /mnt/sdcard/DCIM/*.*
adb.exe -s DevID shell rm /mnt/sdcard/Pictures/*.*
adb.exe -s DevID shell rm /mnt/sdcard/Pictures/Screenshots/*.*
adb.exe -s DevID shell pm clear com.mobeera.pdfmax
adb.exe -s DevID shell pm clear org.mozilla.firefox
adb.exe -s DevID shell pm clear com.android.gallery3d
adb.exe -s DevID shell pm clear com.google.android.youtube
adb.exe -s DevID shell pm clear com.qrd.omadownload
adb.exe -s DevID shell pm clear com.android.providers.downloads
adb.exe -s DevID shell pm clear com.android.providers.downloads.ui
adb.exe -s DevID shell reboot -p
Hope that helps you some!
