Android 8.1 manual update 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 update 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 update.
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 update your Gemini until further information is provided
To proceed, start by downloading the update archive from 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'.
Now, inside the Firmware Update application, tap on the settings icon, in the top right of the screen.
Inside settings, tap on Manual Update.
You should then be presented with a screen as in the screenshot below. Tap on 'Install Now' option on the left.
A confirmation dialog will then appear. By tapping on the 'Firmware Update' button you will start the update procedure. Note the the button might be not fully visible in landscape mode.
Your Gemini will then reboot and complete the update. Once the update is completed you will see the following message.
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.
- LEDison has been reported to crash under some circumstancies - we will update the application in the Play Store soon
- It has been reported that sometimes the Micro SD may 'disappear' - we are investigating, but if this happens to you, just reboot your Gemini
- The Factory Reset does not work on Android 8 - we are investigating this
