If you don't want to wait for the Sprint Epic 4G's Android 2.2.1 Froyo update to push out over the air, you can now manually update your phone. Here are the steps to manually update your Epic 4G to Froyo:
- Download the update from Samsung. Hint: Just download the Mac version, even if you have a PC. The file you download will be the update.zip.
- Move the update.zip file to your SD card (instructions).
- Turn off your phone.
- Hold the Volume Down and Camera buttons, then press the power button.
- The update should automatically launch itself. Sit back and relax.
- Reboot the phone.
Couldn't be much easier than that, and it beats the hell out of waiting any longer. No ODIN, no wiping, just pure Froyo goodness. (If you PC folks want, you can download and install the desktop version of the updater, which works just fine, too.) If you still need more help, check out this thread in the Android Central Forums. Thanks, jamex!
