Sprint says the Epic 4G update to Android 2.2 is only a test build, here’s how to install it

Over the weekend it was discovered that Android 2.2 was available for the Samsung Epic 4G, but a post on the official Sprint forums says it is only a test build. They warn users not to flash any update files that come from 3rd party developer sites, but the test Android 2.2 build (DK28) is still on Google’s servers so you can trust it is safe.

Sprint warns this software is not yet approved and they recommend that users refrain from loading it, but as long as you understand what you are getting into then go ahead and flash away. Some users at xda-developers have experienced issues with this test build, but others flashed it with no problems at all. The good thing is that it’s possible to return to the latest official build and wait for Android 2.2, but there is no telling how long that might take for Sprint to release it.

To help in the flashing process, here is a quick video that explains how to un-root your Epic 4G and return to a stock build so that this latest build can be flashed.

Manually install Froyo on the Samsung Epic 4G

  1. Download the zip file from Google’s servers
  2. Rename the file to “”
  3. Save file to root directory on your microSD card
  4. Boot the Epic 4G into recovery mode (hold down the “Volume Down” button, “Camera” button, and “Power” button simultaniously)
  5. Install or apply the “” file from recovery. Use volume keys to navigate menu. Home key is select.

Below is a statement from the Epic Product Manager regarding the leaked release (DK28):

“Sprint is working on a software package for the Samsung Epic4G that will upgrade it to the Froyo version of Android.  Over the weekend, some users were able to access and download a test build (DK28) for the Samsung Epic from some 3rd party developer sites.  Unfortunately, this is not approved software for Sprint production devices and we strongly recommend that users refrain from loading it.

Software version DI18 is the current production version of software.  When new versions of software are available, users will receive a notification from Google on their device stating that an upgrade is available for download and installation.  While we are unable to communicate a firm delivery date, rest assured that we are working on a software upgrade to Froyo and hope to have it out in the very near future.”
