Here's another (yes another) practical guide for those of you who are NOT rooted and updated to DK28 and want to go back to DI18. There are many out there with different download links, so I wanted to provide one that has the latest links that worked for me (as of 12/6/2010). 1. Get the USB drivers for the Epic here: Samsung Select "Software" in the bottom. The Description should say "Device(Install),USB Driver (Software) (ver.1.0)" 2. Install the USB drivers on your system. 3. Download ODIN from here: http://www.sdx-downloads.com/devs/noobnl/Odin3epic.rar Extract the file. You will be using the Odin3+v1.61.exe 4. Download the TAR file from here: http://firon.net/xda/SPH-D700-DG27-8Gb-REL.tar It is VERY important to make sure you get the full file or else you will get errors and failures. My filesize I read on explorer for this tar is: 255,690 Kb 249 MB (261,826,560 bytes) 5. Start ODIN. (Open the Odin3+v1.61.exe file that you extracted earlier) 6. In ODIN, click on the "PDA" button. It will open up a prompt. Select the "SPH-D700-DG27-8Gb-REL.tar" file that you downloaded earlier. It will automatically check the check box next to the "PDA" button after you select the file. 7. Uncheck the "F.Reset Time" check box 8. Turn off your phone. Unplug the battery and plug it back in. Hold down the "1" key on the keyboard and keep holding it down while you power your phone on. It should eventually display the DOWNLOAD MODE with the droid character as a construction worker. 9. Plug your phone in. Assuming the USB drivers installed successfully you will now see one of the "ID:COM" fields turn yellow and have a COM # assigned to your phone. It will vary depending on which USB port you plug in. 10. Hit Start. It should take less than 3 minutes and you will have stock DG27 again. NOW to update to DI18 do the following: **credit to Andrew Ruffolo on Android Central for the following** 1. Download the following file and save it in your phones root directory (not any special folder) - which basically means when you use "USB storage" on your phone when it's plugged into your PC...drag the update.zip file into your phone where you see all the folders. Do NOT put it in any folder. update.zip - 4shared.com - online file sharing and storage - download 2. make sure its named update.zip and nothing else. if its named something else like update1.zip, change it to update.zip 3. turn phone off 4. Hold down camera, volume down and press power. 5. Use volume down to select SDCard: update.zip 6. Press Home on the capacitive buttons to select. 7. Phone should automatically install and reboot.
