Have you watched qbking77's videos on "How to return to stock"?
No, you haven't. You still can though, and I would suggest that. They are great vids and easy to follow along to. You can pause, stop, even rewind them to keep up
All kidding aside, check them out. It will get you where you want.

You might wanna try to flash eb13 and after you use odin to flash to eb13, connect to wifi and manually update your software via ota to ec05. Go to settings and click about phone then system updates and select update android. This should get you back on ec05. I had the same problem when i wanted to go back to ec05. But i gotta say the second time i flashed ef02 all my functions that didnt work previously now work flawlessly. Although i did redownload the ef02 file again so maybe my original one was a bad download...Good luck to you...Dont forget to update us....

still didnt work...and idk if its just my epic but every rom ive tried the battery is off really bad...it would take me a half an hour just to go up 3%...also i backed up my stock 2.2.1 tw and i tried restoring it but it wouldnt restore through clockwork(i have the purple cwm)it would just stay on the samsung bootloader and vibrate constantly. I would have to use another rom just to fix it...i just want to restore it back to stock with root but i have yet to sucessfully achieve that....would appreciate that i looked at the videos but none showed how to restore back to stock

U might want to go back as far as d107 or d118, their eclair versions but u could update back to froyo using ota updating. In your case I would start from the bottom and work my way back up.

[Q] Question about updating

On the Samsung website, they offer the program that upgrades your phone to the official EB13 2.2 software. My question is, will I be able to use this if I am rooted and running DK28, or would I have to unroot and reset my phone before doing this?
Yes you should go back to di18

If you go to this thread and go to the Alternative Method, it has a link to download the full EB13 and you can odin straight to that, instead of having to go back to DI18 and then updating
http://forum.xda-developers.com/showthread.php?t=963652
That exe from Samsung you are talking about should work too, it flashes EB 13 just like odin...no need to go back since it just wipes and flashes anyway
Alright, thanks for the info

[Q] How to "upgrade" from DK28 to EC05? [Q]

I did my research in and out of XDA w/o finding specific method on how to go about doing this :s From what I've read in these forums I found 2 different files from k0nane that, according to the people that posted them and my limited knowledge of this, lead me to believe that it will do what it is I am asking. One is "k0nane.info/rom/SPH-D700-EC05-8gb-REL.tar", and the other is "k0nane.info/rom/acs-ec05-modem.tar". (being a new user I can't directly link to the files)
I would like to know which one is the one I need to make my phone EC05. Now that summer is here I'm interested in installing ROMs, themes and trying to brick my phone ^ .^ Thanks in advance
PS: If it isn't too much of a bother, where in Odin does one place a .tar file? I've only used Odin a few times a while back; last time to put DK28 on my Epic :3
You used the first one you named. You put it in the PDA slot in Odin.
The second one is only the EC05 modem, which is pretty much the "radio firmware".
Just know that Odin does wipe out everything on your phone except your SD card.
Is there a way to upgrade from DK28 without wiping your phone?
My phone is rooted and I have CWM v2.5.1.
I have Titanium installed.
Thanks.
Search the forums for user qbking77 I think is his nick he has excellent videos on how to use odin and other stuff. I have links in my sig too but not sure if my sig shows well using xda premium.

Is there a rooted version of EC05 that will work directly from DK28 without having to go back to DI18 and lose everything? Or is there a way to backup apps and restore after ODINing ?
you can backup everything with titanium. Apps, data, contacts.. everything.

So just to be sure....
1. Titanium backup
2. Odin to DI18
3. Upgrade to Ec05
If I have CWM 2.5.1 is it necessary to upgrade to latest version?
Is step 2 necessary or can I go directly to EC05?

I have the program on my desktop pc, but not my laptop. can ANYBODY please direct me to the Non-odin way to flash the Samsung Epic back to stock? I am able to update the phone over 3g/4g after that for updates.

[Q] How to restore "Stock" recovery and unroot without reflashing the ROM?

Is there a way to replace CWM with the stock recovery?
Also, is there a way to unroot?
I am currently on EC05 rooted with CWM purple but I'd like to unroot and remove CWM without having to reflash and spend hours reinstalling all my stuff.
Yes. I can't gve an exact guide right now, but you should delete superuser.apk and /system/xbin/su or /system/bin/su. Then find the stock recovery

DCrocks put out a stock recovery flash. Then I guess you would remove Superuser. Why do you need to do this? If you go to Development in the stickies there is the How to fix a semi-bricked Epic. Dyeha posted links for this in one of the last posts.

I'd like to use the OTA GB whenever it arrives. I'm on stock EC05 except for root and CWM, so I think reflashing stock recovery should allow the OTA without losing my setup.
I refuse to have stock anything on my phone; I continue to wait patiently for a GB that is fully modded and hot rodded

I tried the above zip, but it caused my phone to hang on restarting; only odining something could get my phone back.
Like the above poster, all I have is a rooted stock EC03 (with no system apps removed whatsoever), and all I want is to update to EI22, either OTA or from the Google download, without losing my data. Does anyone know of another way to restore stock recovery to help make this possible?
Thanks much!
I wish I could do the same since I'm on stock rom + root. But since I'm already getting the OTA gingerbread prompt, I'm going to go ahead and try to ODIN to EC05 then upgrade to Gingerbread then root again.

That will certainly work. I did it and it worked fine. But I didn't want to lose my settings and data, and I'm not adept enough with Titanium Backup, so I didn't keep things that way. Still trying to find a way with keeping my settings/data...

If you followed the instructions right, you've already hosed what was previously your "stock" rom.
First, did you make a backup?
If so, wipe and restore.
If now, flash a new rom.
Did you already update the modem?
If its still on EC05, flash an EC05 rom.

Dude, just restore your nand backup.
If you want to go back to stock and become unrooted, go to youtube and search samsung epic return to stock. Watch qbkings video. You will need the ec05.tar file, samsung drivers for your pc, and one additional file that should come with odin, and a valium. There are turtorials everywhere around here, but for step by step "easy" instructions, use qbkings video.

Two options if odin doesn't see your phone. Try a different cable I bought mine at staples 15 dollars for a better 6 foot cable. Second option is remove the battery hold down 1 and power insert battery. That should get you back in. Then odin to stock ec05. Find a rom of your choice like randomrom thunderhawk. After it installs use the ec05 to ei22 modem flash. That is the method that I upgraded worked like a champ.
If odin doesn't see your phone, try disabling your antivirus and firewall that was causing me problems a while back with Norton I think.
