## The context

Due to a server incident, previous versions of /e/ OS are no longer available. We strongly recommend installing the latest available version to ensure optimal performance and compatibility. Upgrading to the latest version should resolve any existing issues.

{% include alerts/tip.html content="Important: Before proceeding, back up all data on your device, as skipping OS versions may result in data loss." %}

- To switch to new /e/ OS version, from older versions there are 2 possibilities.

### Option 1: Use "Local update" function in /e/ Os Updater

{% include alerts/tip.html content="This feature is only available on Android T or higher, and this feature was unavailable between /e/ 1.16 and OS 1.20." %}

In case your version is not in this range, please use the following steps:

- Browse to https://doc.e.foundation/devices

- Find your device, and click on `Official install doc`

- Click on `install` under command line

- Under `Downloads for ....` click on `T stable`

- Find the latest image file to download it, but If the link contains a package name starting with IMG-, remove IMG- from the link, so that package becomes e-*.zip

👉  **Example**:

Instead of downloading 

https://images.ecloud.global/official/FP5/IMG-e-2.5-t-20241108446629-official-FP5.zip

download:

https://images.ecloud.global/official/FP5/e-2.5-t-20241108446629-official-FP5.zip

- Transfer it to the phone with memory, if not downloaded from the phone already.

- Click on: `settings` > `updater` > `3 dots on top right` > `local update` > `select file`

- Complete the installation

### Option 2: Sideload via ADB

👉 Install ADB by following https://doc.e.foundation/adb
