Step 2: Extract Win32DiskImager zip

Make sure all the files are extracted or else the process will fail.


Step 3: Insert USB or SD drive


Step 4: Write to disk

 

 

 

 

 

 

 

Be careful not to select an external harddrive. It WILL wipe the drive completely! 

Click the folder icon to select the bin file The bin file is located at 
\\rcit-techdata\Tech\Acer ASP\C740\Benetton_Edu_RMA_20150203

All data will be erased from the USB drive/card once you hit Write! 

Click the Write button Click Yes on the Confirm overwrite dialog
The image is now being written to the drive.

Step 5: Disable HW Write Protect Switch

Remove the screw marked red, place the bottom cover back on the system. Upclose view of the hardware write protect switch

Do not put the screws back in since you will need to open the system again

Placing the bottom cover on the system enables the battery


Step 6: Enable developer mode


Step 7: Using the RMA SHIM

If the device is powered off, press ESC+REFRESH (F3)+POWER to turn the Chromebook on


Step 8: Start the Factory Test

If using a barcode scanner, make sure to click the enter Seiral number filed after scanning the serial number and before pressing enter. If the barcode scanner is set to tab after scanning, it will go to Mark Failed button and fail the test.

 

The device is now ready to get enrolled to the enterprise environment.
