Android 8.1 manual upgrade for Gemini 4G (x25 and x27)

Please note this guide is for Gemini 4G devices only (both x25 and x27 models), not for Gemini WIFI devices.

The following guide will help you to install the Android 8.1 upgrade on your Gemini 4G, both x25 and x27 model. This guide is for an Android-only Gemini firmware, a multi-boot Gemini guide will be available soon.

If you have trouble updating your Gemini using the over-the-air udpate mechanism you can follow the guide below to perform a manual upgrade.

IMPORTANT INFORMATION for users in Japan on the NTT DoCoMo network: we had some reports that the network is not detected by the Android 8 firmware. We are investigating - please wait to upgrade your Gemini until further information is provided


To proceed, start by running the Firmware Update application. Inside Settings, scroll to the bottom and tap on 'About phone'.

A new version should be detected, please make sure you are connected to a WIFI network.

By tapping on the Download button you will start the firmware update download. If the download completes successfully you will just need to tap on the 'Install Now' button to start the update process and then tap 'Firmware Update' to complete it. In case you have troubles downloading the update, please continue with the guide.

If your download stops and cannot complete successfully you can complete the process manually. To do that, first tap on the square button on the soft keys (bottom right) as in the picture below to bring up the task manager.

After that, close the Firmware Update by swiping it out of the list as in the following screenshot.


Now, run the File Manager application and look at the root folder in Internal Storage. You should see a file called ota.zip. Delete the file by selecting it with a long tap and tap and then using the Delete  action on the menu that appears when tapping on the 3 dots button as in the following screenshots.

After that, you can download the firmware from a different location: http://support.planetcom.co.uk/download/Android8_4G/ota.zip. It's easier to download this archive directly from your Gemini, where you just need to open a browser and point it to the URL above. The file will be downloaded in your Download folder.

You can also download the file on a computer and copy it to your Gemini Download folder at a second stage.

Once the file is downloaded, open the File Manager application

In File Manager, browse the Download folder inside the Internal Storage to reveal the downloaded ota.zip archive. Make sure that the file you just downloaded was not been saved with a different file name. In that case rename the file to ota.zip.

Next, we will have to copy the ota.zip file inside the root folder of the Internal Storage. To do that, simply long tap the ota.zip file to select the file and then use the copy icon that will appear once the file is selected, as in the following screenshot.

After that simply go back to the content of the root folder of Internal Storager.

 Now, tap on the paste icon to paste the ota.zip file in the root folder.

Please note that if you already have a file called ota.zip, then the just copied file will be renamed with an extension. In that case, please remove the ota.zip file in the root folder of your Internal Storage and copy/paste the file again.

Now that we copied the update archive in the correct location, we need to start the update process. Inside Settings, scroll to the bottom and tap on 'About phone'.

Next, tap on the first option 'Firmware Update'.

Please note that the Android 8.1 update might trigger a number of upgrade scripts and application updates. As a result your device might appear slower and feel hotter than usual for some time.


Notes on using your Gemini with Android 8.1 

Re-starting and booting Android 8.1 for the first time

The first boot of the ungraded Android 8 Gemini will take a while as the system is booting for the first time.
Once the Gemini has restarted, it will still take some time until the installation is fully complete. You will get an on-screen message that the Android update is complete. After that the device may still feel a bit sluggish as file formats and data is being adapted for each application to Android 8 formats. This process should last a maximum of few hours, but it is dependent on the storage of your device. The more data you have the longer the process may take. You may feel the device even getting warm from the processing of this data. 


Android 8 security 

Because the security frameworks are different in Android 8 and Android 7, you may be asked to re-authenticate your Google or other accounts as well as to re-grant permissions for the apps that you are running.
Typically you will be asked to grant specific permissions with an on-screen message.
If you notice any apps crashing, this may be because they are simply not compatible with Android 8. Please check in Settings->Apps if all the required permissions have been granted to the app that is crashing, just in case it is a security issue.


New features in Android 8

We have introduced some new settings for the Gemini in Android 8.
You can now move the Android Navigation bar from the right hand side of the screen to the left hand side using the "Move Navigation Bar to the left side" setting.
You can also completely remove the Android Navigation bar from the screen by using the "Hide Navigation Bar" setting.
You will need to restart the Gemini for this feature to take effect. 
When the Navigation Bar is hidden you will need to use the keyboard shortcuts for the Go Back, Go to Desktop and Apps list functions.
The keyboard shortcuts for Go Back, Go to Desktop and Apps list are as follows:
  • Back - Esc (escape key)
  • Desktop - Fn + d
  • Apps - Fn + a



There is a new keyboard shortcut to rotate the screen:
  • Shift + Fn + R will rotate the screen from landscape to portrait and vice versa.

The new App Bar is now scrollable. You can scroll left and right and extend the number of app icons in the app bar.
