However , if you used the [http://support.planetcom.co.uk/partitionTool.html Gemini Partition Tool] to create a custom Gemini partition table, for example to obtain a custom multi-boot Linux/Android installation or a rooted Android, then you will have to update Android manually.

Let's start by downloading the updated Android Base firmware. To do that, simply visit the [http://support.planetcom.co.uk/partitionTool.html Gemini Partition Tool] page, select your Gemini version (Gemini x27, x25 or WIFI only) and click on the '''Download Base Firmware''' button. Make sure you select the right firmware for your Gemini. <span style="color: #252525; font-family: 'Source Sans Pro', sans-serif; font-size: 15.008px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">If you are not sure about your Gemini version, just check under Settings -> Wireless & networks. If you see a menu called SIM cards, then you have an x27 Gemini, otherwise you have an x25 Gemini.</span>

See the following screenshot for reference<br />:</span>

The most important thing here is to untick the userdata partition, which contains your data, so that your information is not deleted from the device. If you accidentally flash the userdata partition as well, then all your data will be lost. If you have a custom multi-boot Gemini as used in the screenshot, then most likely a few other partitions will already be unselecteddeselected (in the screenshot, you can see that the boot, linux and boot2 partition are deselected), this is fine.As a rule of thumb, at least the system partition and one of the boot partition (boot, boot2 or boot3) should be selected. Make sure you selected the '''Download Only '''option.   <div style="margin: 0.4em 0px 0.5em; color: #252525;" source="" sans="" pro="" sans-serif="" font-size:="" 15="" 008px="" font-style:="" normal="" font-variant-ligatures:="" font-variant-caps:="" font-weight:="" 400="" letter-spacing:="" orphans:="" 2="" text-align:="" start="" text-indent:="" 0px="" text-transform:="" none="" white-space:="" widows:="" word-spacing:="" -webkit-text-stroke-width:="" background-color:="" ffffff="" text-decoration-style:="" initial="" text-decoration-color:="">To start the flashing process, just click the big '''Download''' button, connect your Gemini to your PC and restart the Gemini. Once booting, the flash tool will detect the unit and will start flashing the device with the selected firmware.</div><div style="margin: 0.4em 0px 0.5em; color: #252525;" source="" sans="" pro="" sans-serif="" font-size:="" 15="" 008px="" font-style:="" normal="" font-variant-ligatures:="" font-variant-caps:="" font-weight:="" 400="" letter-spacing:="" orphans:="" 2="" text-align:="" start="" text-indent:="" 0px="" text-transform:="" none="" white-space:="" widows:="" word-spacing:="" -webkit-text-stroke-width:="" background-color:="" ffffff="" text-decoration-style:="" initial="" text-decoration-color:="">The following screenshot shows a successfully completed flashing process:</div>  <div style="margin: 0.4em 0px 0.5em; color: #252525;" source="" sans="" pro="" sans-serif="" font-size:="" 15="" 008px="" font-style:="" normal="" font-variant-ligatures:="" font-variant-caps:="" font-weight:="" 400="" letter-spacing:="" orphans:="" 2="" text-align:="" start="" text-indent:="" 0px="" text-transform:="" none="" white-space:="" widows:="" word-spacing:="" -webkit-text-stroke-width:="" background-color:="" ffffff="" text-decoration-style:="" initial="" text-decoration-color:="">[[File:Screen_Shot_2018-06-21_at_12.08.02.png|center|799x602px|border]]</div>
