[Epic 4G Android Development] jdelano:
My experience and results

Hey all

Wanted to share what I did and how things went.

First I will preface this by saying, I have been reading these forums since I was given my Epic for xmas. To see what was available and which rom seemed to have A) the least issues and B) the best support. It was clear that ptfdmedic not only does great work but more importantly is very active here, even though his life pretty well packed with excitement. Bravo sir, you earn every donation that comes your way.

So last night, I downloaded 2.5 + EXT4 and the files needed for the 3 step instructions. All on the first couple pages of this thread. If you're just coming to this ROM, these steps work, however it should be said that you must use Odin3 to install the DK28 Modem on your phone, that is a little lost in the volumes found in the first 3 pages of this thread. So read before jumping in head first.

I found a nice youtube video by randyshear, that shows the process of using odin3 to do that, search google for "SAMSUNG EPIC 4G HOW TO ROOT AND ADD CUSTOM 2.2 FROYO ROM" on youtube. He shows the Odin stuff and how to boot into recovery, where to go to clear the items (3x each) and then run the install of your ROM, highly recommended if you're doing this for the first time. Also of note, I found people had problems if they flashed both PIT and DK28 modem, GPS issues to be specific. So I just did the modem as that was the thing mentioned as a must have.

So I did that and went to the 3 steps, all went well <grin>

Couple issues for me:

1. My backup pro can't find the backup I did before doing this. I copied the entire contents of my SD card to my computer before hand (after running the app and call log/text msg backup). I copied them back over to the phone after installing my backup pro and my backup pro doesn't see them, not a huge deal for me. I don't have a ton of apps.

EDIT:

Found this on another forum that solved this issue for me

Go to options in MyBackup Pro and uncheck "Use SD card for local" (the top one). If you're still not getting it move the rerware folder into /sdcard.

2. 3g/4g. I have to say my 4g reception actually seems better. The modem help that??? BUT .... before (using stock 2.1) the 3G icon would always be in my notification bar and if 4G wasn't available it simply would switch, no interruption. Now the 3G goes away and I get a no network available message retry .. i click yes and 3G will come back (sometimes needing a few retries) again for me not major but a little frustrating

3. contacts would not let me out. I found in this thread; that the fix was to remap the contacts button in launcher pro to contacts. that worked for me as well. (littlepr on page 7, thanks for posting that)

That is it when it comes to anything different from what was expected, nothing is a show stopper.

I am using wireless_tether_2_0_5-RC1 and it works great, also installed the swype keyboard and that is working great too.

I can tell you the phone feels REALLY fast.

Here are some benchmarks from before and after (because people LOVE benchmarks <grin>)

stock

linpack : 8.1 7.9 8.1

quadrant: 927 927

quadrant : 1387 1682

speed test

missed 480kbps up

1107 kbps down 330 kbps up

792 kbps up 548 kbps up

I think the data is quirkier because of the 3g issue I outlined above.

Battery seems really good too, I charged it (as your should have a full battery before flashing) then did the steps, left it unplugged all night and have setup email and still have 32%

So 2 thumbs up !!

I hope this helps someone, lord knows everyone's posts here helped me immensely when deciding which to use. Thank you to everyone who posted, not only their issues and the fixes, but the positive posts. They are as important as issue posts for sure.
