How To: Update Sprint Epic 4G to Android 2.2

Filed under Guides by Korey Nicholson on December 4, 2010 at 4:59 PM

We’ve just reported that Android 2.2 has been over-the-air updated to the Sprint Epic 4G. Edit: This update was just for beta testers and may be OTA’d to others later. Until now, users not receiving the update yet have been out of luck. Below, we’ve uploaded an update.zip to allow you to install Android 2.2.1 Froyo on your Epic 4G. Go ahead and push the file to your internal SD card. From there you can flash the file in recovery mode.

For best results, flash clean to DI18 before upgrading to DK28 Froyo.

Instructions: Update Android 2.2 Froyo for Epic 4G

Intended for those going from stock Android 2.1 to the latest firmware.

  1. Download the required update.zip file
  2. RENAME the file to “update.zip” (If you get an error while flashing, your file might accidentally be named “update.zip.zip” due to Windows’ file renaming system. Simply rename it to “update” to make it update.zip and flash)
  3. Move the file to your storage on the Epic 4G (Mount USB storage and drag the update.zip into root folder)
  4. Boot your device into “recovery mode” (if you don’t know how: click here)
  5. Apply the sdcard update.zip from Recovery Mode
  6. Congratulations! You now have Android 2.2.1 Froyo (DK28) on your Samsung Epic 4G from Sprint!

    I followed the instructions listed and my Samsung Epic phone works FASTER! I can now use watch flash video and use Skype to make VOIP calls. I honestly don’t know what everybody is having problems with. I’ve not had a single problem since upgrading my firmware. The only curious new features is that I now have two portrait views on the screen of the phone, which makes it hard to tell if it is “upside-down” while sideways -yeah I know, weird. Other than this, the phone works perfectly.

    You obviously were to stupid to know how to do it in the first place. The GPS and 4g are easily fixed by following a few steps.

    If I placed the OS/Zip file on the SD Card and installed in recovery mode. Can I still return it back to stock using Odin?
