Start over. Download STOCK DK28 from the wiki, and odin it. Then run one-click root with redirect, and then run through the steps over again. I was in the same place you were.
[Epic 4G Android Development] ryno502:
You will break your gps if you odin straight to dk28. Mine breaks anyway. I recommend flashing to di18 get a lock then update.zip to dk28
[Epic 4G Android Development] leatherneck6017:
Not true. Works just fine for me, and believe me, I've Odin'd my ass off since DK28 :p
[Epic 4G Android Development] ryno502:
Hmm maybe im just unlucky then. odin breaks my gps unless I go to di18 and get a lock first
[Epic 4G Android Development] leatherneck6017:
I've read about people having that problem, I think it varies by phone but it seems most get away without having to do that workaround. Guess I'm one of the lucky ones!
[Epic 4G Android Development] TurboFool:
Every indication I've had is that that's just placebo. Results are random, and people often don't properly evaluate the GPS before they determine whether or not it's working. In my case I went straight to DK28 and my GPS is working as well as it ever does (frequently loses the signal, then picks it back up again within a minute). But then again I went to that straight from a previously working ROM, so perhaps that's the same as going DI18 first.
[Epic 4G Android Development] SnoopDawg:
So I completely facepalm'ed mine while doing. I was getting the lock ups on the samsung screen.

re-flashed with ODIN

Thanks,but bear with me..Files are extracted to desktop..What would the whole command be type as?This is my wifes phone,Im use to my Evo..Now that i started playin with it ,i cant put it down until i do this..hehe..
[Epic 4G Android Development] leatherneck6017:
That would be a painfully long file path, for me anyway. It will also vary by a) what version of Windows you are running, and b) what the username of your active login is.

For example, for me, using Windows 7 it would be "C:\Users\Home Fast\Desktop".

Easy solution is to extract the .zip to your root drive like C:\ext4 or something similar. Then from a command prompt all you would have to do is type cd c:\ext4 and voila, you'd be in the correct directory to run the adb commands.
[Epic 4G Android Development] TheBurgh:
Gonna give this a shot shortly. So all I need to do is flash the prepare.zip first, then run the commands

Got it figured out. Sorry for my ignorance with abd. Still green with some things

when I type reboot recovery in adb it just boots the oem recovery...

That means that you don't have the Clockwork Redirect installed. It is a prerequisite to installing this mod.

You might want to reapply it again. If it were working correctly, you would be booting into Clockwork.

I finally fixed after bricking my phone while updating to ext4.... damn cables :D I want to make sure the kernel is flashed what is the kernel # ? 2.6.32.9 ? Also is there a GB keyboard that will work on ext4 ? I tried to flash the one I was using but it does not work. Thanks
[Epic 4G Android Development] jcluo:
I followed the instructions but it is not working.

I ran the prepare.zip and saw the version number 2.5.1.2.

But when I ran install_ext4.bat, I got the following errors:

Pushing the kernel modules
failed to copy 'jbd2.ko' to '/tmp': Read-only file system
failed to copy 'ext4.ko' to '/tmp': Read-only file system
Mouting the jdb2 and ext4 Kernel modules
insmod: can't open '/tmp/jbd2.ko'
insmod: can't open '/tmp/ext4.ko'
Unmounting filesystems

...

If I run install_ext4.bat in CWM, it always get "device not found" error, even after I unplugged and replugged the cable.

Can anyone post a precise instruction?
[Epic 4G Android Development] kilmarac:
I have the same problem. I have run the 1clickroot with redirector probably 10 times now and when I do adb reboot recovery to try and run this mod, it puts me into the samsung OEM recovery.

I have tried on both the DI18 stock and the DK28 stock from the wiki.
[Epic 4G Android Development] sniperkill:
Which DK28 are you using? I think the only one that works is the origional DK28. You cannot use none of the extended ones... look on page 14, I got posted a little bit different of directions that migt work better for you, also on the next page (pg. 27), "prophour" posted some pretty clear directions also. Everyone should read the entire thread b4 asking any questions... there's a lot of very useful info in there ;-)
[Epic 4G Android Development] mictek:
I had many issues, but most were solved by reinstalling my samsung drivers mutiple times. For some reason adb would stop seeing my device. I also had to odin dk28 again and finally got everything working. The dk28 I used I think is the same one here http://xdaforums.com/showthread.php?t=794138. The really only issue I had was that my drivers had to be reinstalled mutiple times. Once your in adb type adb devices and make sure you phone is listed if it isn't don't try the next step until you get it listed. Hope this helps.
[Epic 4G Android Development] Zei:
No offense but this should have been tested more before releasing to the masses. This is reminding me of using odin smh. Ppl "bricking" left and right without proper walkthroughs
[Epic 4G Android Development] R.O.C.:
Long time lurker, though I haven't read ALL of the pages.... I would be forever grateful if someone posted a YouTube video of how to do this.
[Epic 4G Android Development] pjjohn73:
Thanks for the link....

It looks to be a FULL DK28 ROM (kernel, modem, filesystem) that can be ODINed. What pit file do you need to use to do the ODIN? Same as the DK28 Modem or a different one? THANKS...
[Epic 4G Android Development] :
Seriously?

Do this.

Odin DK28.tar

##RTN#, MSL, Reset. (just to be sure)

Extract the 2 zip file to the sd card

All the other files go into folder "ext4"

Put that folder in the root of the C:/ drive

Turn on debugging

Connect phone

open cmd.exe

type: cd/

type: cd ext4/

type: adb reboot recovery

wait

flash prepare.zip

wait

unplug, then plug in

type: adb reboot recovery (if it fails, go to advanced then reboot recovery)

wait

look for 2.5.1.2

unplug, then plug in

type: install-ext4.bat

wait

Wipe data x3

Wipe cache x3

Wipe Dalvik x3

install .zip Quantum ROM 2.5

install .zip KERN-DK28EXT4.zip

Reboot

Confirmed working.

[Epic 4G Android Development] JustinLoe:
Lmbo, If you can't do a one click run bat, you should never even begin to attempt to root your phone to begin with or enter a forum titled "development". The instructions are laid out fine in the op, and if you didn't read them correctly it's your own fault. Besides Odin is easy as pie if you brick; Download Tar, place tar in correct table, click, done.

Anyways, Thanks a ton for the work Dameon, phone runs outstanding.
[Epic 4G Android Development] pjjohn73:
prophour

Can you link the DK28 you ODIN'ed and the pit?

I got to the "Wipe Dalvik x3" and everything was fine but then for some reason I did not have an option to get back to last clockwork recovery menu to Flash, so I "rebooted into clockwork recovery" from the advanced menu. It went back to the older version of recovery.

So now I need to ODIN my phone and would like to ODIN strait into DK28 not KI18, which I have and update version for and the full ODIN version w/o a pit.....

Thanks

PS: and yes I have been searching for it, before asking.....
[Epic 4G Android Development] JustinLoe:

[Epic 4G Android Development] hayabusa1300cc:
I agree, it's your fault if you can't folie directions... Easy as reading, and following. Always helps to read throughout the thread as people are asking the same questions.

It's well known that you will have issues depending on what usb cable you use. Lots of people are blaming windows 7 on their problems. It's not. Use a quality cable, I'm using htc. I had same issues on windows xp before I changed cables a week ago.

Other than that, make sure you are running compatible software as prior stated (redirector)
[Epic 4G Android Development] mictek:
I didn't use a pit file. I used a Tar file. If you follow the link I believe you can find the tar file. I know I returned to stock froyo after I got stuck on the Samsung screen because of a stupid mistake. Then everything worked pretty simply.

Just a side note. It appears I have two versions of CMW. In order to install stuff you need to be on v2.5.1.2. I can boot to 2.5.1.0 but it screws stuff up if you try to install files.

Very important your device is seen by adb. I had issues getting mine to be seen all the time. I used mutiple cables. I think it's my computer, but either way run adb devices to verify.
[Epic 4G Android Development] pjjohn73:
Thanks for info, but I think I am missing something. If you used the Tar file in ODIN, don't you need to use a PIT file also to map the installation? So, how did you install the Tar without a Pit?

Also, how do you boot to v2.5.1.2 VS. v.2.5.1.0 after your all done with this?
[Epic 4G Android Development] pjjohn73:
Thanks... but...

I already have the DK28 ROM Tar and the Modem Pit, but using the Modem Pit does not seem to work on the DK28 ROM Tar. It only seems to work on the MODEM Tar.

Edit: When using the full DK28 RAR and the Modem Pit, it seems to hang on the factoryFS (the phone screen turns purple and then hangs)

Edit: Decided to go back to the DI18 RAR for a full ODIN recovery and even that is not working now. I have done that multiple times before with no issues... not sure whats going on now.

Edit: Well I tried over and over and over again and finally ODIN took. (was getting nervous) LOL
[Epic 4G Android Development] mictek:
I followed the directions to return to stock. I may be mistaken. Once all was done I installed the midnight rom and use the quick reboot. That gets me to the 2.5.1.2.
[Epic 4G Android Development] smoothone:
I agree it should have been tested more! This instructions you posted are clear and concise for a newb! They are not what is posted in the OP! I know what I'm doing and even fixed the bat file from the original steps and redirector was not working. I had 2.1 installed like he said in the OP and it didn't work for me untill I Odin to the DK28 tar and then installed redirector! So I would agree that the instructions were slightly vague and inaccurate!

[Epic 4G Android Development] thetoady:
ok, so that sort of answers the Q, "basically its the direction android is going", though I'm wondering why this instead of ext2 (are they really concerned about fsck times?)
[Epic 4G Android Development] Dameon87:
Ext2 has no redundacy. If something happens then your data is gone.

It is faster, but on a phone redundancy is pretty important.

[Epic 4G Android Development] SRobby:
Worked great for me

1. Flashed DK28 Stock not extended, extended failed for me.

2. install one click root + Clockwork 2.5.5

3. copy over files to sd card root

4. from home screen, from win 7 x64 cmd -> adb reboot recovery

5. from cwm flash prepare.zip.

6. send adb reboot recovery command a second time.

7. verify correct cwm version.

8. run cmd "adb devices" to verify connectivity.

9. run install-ext4, wait...wait...wait...

10. Flash Quantum 2.5

11. wait for google to finishing sycning all my crap, titanium restore.

12. Play mini-squadron while at work

Perfect, not a single problem thanks so much.

how ya like this.

If so can someone please post a working link to a rom I can load so I can get redirect working? I looked for quantum 2.1 and could only find the new ext4 version. :confused:

Also its worth mentioning, I get an error when flashing dk28 stock rom. it says something about asphalt demo 5 that I dont have in my apps anymore.

Just go copy the link for quantum rom 2.0 and paste it in the address bar and change 2.0 to 2.1. I just did it this morning and it worked just fine.

As for the second part...odin back to dk28 and rerun one click root w/ cwm redirector, then install quantum 2.1, then start with the first "adb reboot recovery". After the prepare.zip file is flashed you should be able to "adb reboot recovery" into the .2 version of clockwork.

[Epic 4G Android Development] mkasick:
The STL is responsible for wear leveling. ext4 is used over the STL, so like RFS it benefits from STL's wear leveling.

Reads don't matter for wear. Both ext4 and RFS use journals, so the number of erase ops between the two should be similar. That said, ext4 uses significantly delayed block writebacks for performance reasons. This means any blocks that are frequently modified will result in fewer erase ops in ext4 than RFS.

It wouldn't surprise me if, on average, ext4 uses fewer erase cycles than RFS and would be better for longevity. From Samsung's own documentation, RFS targets durability ("robustness") as its primary feature, not performance or minimized wear. Seems kind of silly in battery-powered devices where unexpected power interruption is infrequent.
