Android 5.1 to Android 7.1

Upgrading your Door Tablet device from Android 5.1 to Android 7.1.

What you need
To update the devices you will need the following:

  1. 3 USB drives formatted to FAT32. We recommend you use 3 USBs to speed up the process
  2. Download our bundle that includes 3 files you will need for this process
  3. Latest Door Tablet App (from https://www.door-tablet.com downloads)

Basic Steps
  1. Download the Zip file and extract the content within to your PC. You will need a password from us to do this
  2. Copy each file to the USB you prepared and mark the USB drives
  3. Start by inserting USB1 with the Step 1 file and perform a firmware update
  4. Continue with Steps 2 and 3 using USB2 and USB3
  5. Install the Door Tablet App in the normal way and configure it to open your Door Tablet server

We would recommend setting up a hardware profile alongside installing the files needed to set up the upgrade on a large number of tablets. This will speed up the last step in the process.

To start the update:
1. Download the zip file from the downloads page accessible from your door-tablet.com dashboard

Note: contact us for the password for this file.

2. The zip file contains three files. Copy each to one of the USBs you have prepared and mark the USBs
3. Take the image file and save it to the USB. As shown below:



Note: do not expand the Zip files inside the main zip

Install the USB into the Device, and go to settings and go to the firmware update option. At the bottom you should see a button that alerts you to upgrade the firmware.
For example:


Click that and your device should restart. Be aware this might take some time to upgrade. Once completed your device settings should show the Firmware information as below:

Repeat the process in order for the 3 USBs

Reinstalling the app
When the above process is complete the Door Tablet application must be reinstalled. Users with an enterprise server can create a hardware profile for a quick process (as shown here Database 'Door Tablet HELP', View 'Help Documents', Document 'Network Deployment'), However non-enterprise server users will need to do the following:

1. Click on settings > Remote App Update and enter the following:
https://www.door-tablet.com/aio/aio-app.xml
2. Click set, the screen will show the progress of the Application Download

You can now launch the application and connect to your server instance.
