[Epic 4G Android Development] gismo4:
i'll try to post everything here for you. if you know a certain step, skip it.

Step 1 - Download the drivers for your epic to your computer so your computer can recognize it. Make sure to distinguish between 32 bit and 64 bit for your machine. Here's a site that has them for windows - http://www.downloadatoz.com/driver/...h-d700-usb-driver-for-windows-7-vista-xp.html

Step 2 - Odin back to stock dk28. download the dk28 .tar.md5 file. erase the .md5 so the file is simply a .tar file. upload this file to the PDA button. the pit file goes under the PIT button. the pit file and dk28 .tar file are in this link.

the big thing is to get rid of the .md5 extension. after you have the files, open your keyboard. while holding the 1 key, push the power button. it should say something like Downloading. connect the phone to your computer via usb. the odin application should recognize your connection by saying com5 or com6. the number doesn't matter. click start on odin. it should work. a blue bar moves across your phone and odin keeps you updated. once done, it'll reboot back to a stock form of dk28.

Step 3 - On your phone, go to settings -> Applications -> Development and check USB debugging. Download clockwork mod 3.x to your computer. clockwork mod 2.x will not work with midnight rom 3.3. after downloading clockwork mod 3.x, extract it to your desktop. connect your phone. open the clockwork mod 3.x folder and run the run.bat file. this will give you root access. now, connect to your USB storage. since your still in USB debugging mode, slide down the menu bar on the home screen. select the text that says something like, connect to computer to share files. sorry, i forget exactly what. now, on your computer, delete the midnight folder extras folder. put on the midnight rom 3.3 .zip file on the sd card. that's it. 3 button boot into recovery. that is, hold down on the volume key + hold the camera button and then hold the power button. you should boot into clockwork recovery. if this is your first time, it'll take some time running some scripts. just wait a moment while it sets up. once in, go to apply zip from sdcard. find the midnight rom 3.3 .zip and select it. it'll take about 6 minutes to complete and it'll reboot on its own. once on, turn your phone off. (or use quick boot app to get to recovery if you're familiar with it.) 3 button to clockwork recovery. go to the midnight rom extras folder and select your apps. i had issues until i unzipped these specific files. midnight rom standard.zip. google apps.zip. stock mms.zip. swype (beta i think it said).zip. gingerbread kb.zip (just in case there are issues with swype like i had.). that's it. you should be good to go. of course, you can unzip whatever and play with it from there. if you ever get stuck, boot screen won't go away, stuck at samsung screen, just take the battery out and boot 3 button into clockwork recovery and unzip the midnight ROM 3.3 again. and repeat your unzip process from the midnight extras folder until it is the way you want it. :) if you ever get stuck and can't figure it out, just go back to stock dk28 with odin and repeat the above process.

sorry for the long post. i tried to post everything from beginning to end to get midnight ROM 3.3 on your epic. i hope it's thorough enough. :D
