So far so good...
I justed wanted to post to say thanks for releasing a very functional and efficient Froyo ROM for Epic users. Like so many, I was hesitant at first to attempt a ROM install, but I managed to use the instructions here and found the process of flashing with Odin and CW3 to be pretty reliable. I made a few mistakes (using Odin such as leaving the F. Reset checked) but ultimately got past them following the instructions posted. Removing the battery and trying again with a new USB cable and port on my PC seemed to be the answer for my original problems flashing.
Some tips for others:
1) I did have to remove the .md5 file extension for DK28 before Odin would accept it (otherwise got invalid hash).
2) I would NOT attempt installing any applications (nor restoring) BEFORE you apply TrulyEPIC and of the additional .ZIP files (listed on page 1) through CW3. As such listed on page 1 -- I restored both the Sprint and Samsung apps along w/ Voicemail to make the phone seem more stock. I use Home Switcher (as mentioned in this thread from the Market) so I can swap between either AM or Touchwiz as the default Launcher to test them both. Both work equally fine so far for every day use. Finally, I was "forced" to use the Froyo email.ZIP as the Galaxy Tab email client in this ROM will NOT receive any emails regardless of configuration. Others have stated the same results.
3) I did find I lost my GPS upon installing the ROM. I was able to perform under "GPS fix" on page 1, both #3 and #4. #3 only seems to work temporarily, while fix #4 is the BEST option and did resolve getting my GPS to work fine again and all is well with Google Maps/Navigation.
Further questions/comments I have remaining for TrulyEPIC are:
1) When I did the stock DK28 flash with Odin from SPH-D700-DK28-8Gb-REL.tar, I am unsure whether this applied the DK28 modem to my phone? My assumption is yes, but it would be nice to verify via a status screen or market application on the phone. Any ideas as to how I may verify this? Or do I need to flash the modem update separately from the Odin flash listed above? I am hesitant to flash anything separately as the voice and bluetooth functions of my phone are working just fine ATM.
As a side note (and mainly why I ask), I'm a mere 2 miles from 4g Wimax at my house. I read elsewhere the new modem update "expands" the signal reception to 4g. So far, I have not been able to lock on 4g either before or after the flash with Odin at my house.

I was hoping I might actually get a better chance of a lock to 4g at my house (yeah I know - wishful thinking).
2) If I use Touchwiz (yes I know others hate it), it allows for a widget to be placed on the phone desktop called Program Monitor. This is handy because it shows a color indicator bar with the # of still running applications. Often the stock voice search or browser will NOT close automatically when using the Return button on the phone, so this reminds me to close them. It does not appear under AM Launcher anywhere. Is there a fix for this? Or something folks have found that's equivalent or better? It's about my only reason to not keep using AM Launcher 100% of the time. It seems this widget should show up under either launcher...
3) As for the web browser in this ROM... It seems speedy enough, *BUT* without the pinch-to-zoom (with auto *word-wrap*) feature for re-scaling, it seems too broken for everyday use. I have installed Dolphin Mini broswer and it works amazingly well with this ROM (very fast, multi-tabbed, speedkeys etc.). It too will allow a quick toggle (under Toolbox from the menu key) between reporting the broswer user agent as either Android, iPhone, iPad or Desktop PC client-based. Finally, Flash 10.1 works perfectly with Dolphin. You might want to consider an alternative browser component for TrulyEpic going forward IMHO.
4) It seems there was no bluetooth headset dialing as promised with DK28 (Froyo). I have tried 3 different headsets and while they all work just fine *after* dialing manually with the phone, as with Eclair, they still will NOT allow voice activated calling from a BT headset initiation. This is truly a shame as I've heard this added functionality was a part of Froyo for most android phones. My car and old cell (flip) phone both have this support built-in. How can such a capable Android phone have so much functionality elsewhere but not handle bluetooth dialing?
Any responses to the above are appreciated. Again, my applause & thanks to Ragnarokx and all others who have made this ROM possible and contributed vital feedback. This has been my first venture into flashing my Epic and using a FROYO-based ROM. I am quite happy with it as it shows a big improvement in both speed and new functionality!!!
Keep up the great work!
