Hope not
[Epic 4G Android Development] squshy 7:
I'm sure this has been answered, but is there an "uninstall" (reformat rfs)? I've seen some people on other threads say if you flash a rom from the old cwm it puts you back to rfs, but that doesn't make any sense to me seeing as there would still be no script to format the partitions to rfs...

I love this. I applied the ext4 and it is awesome. I checked adb shell just to make sure it worked. If It didn't work would Rfs be in place of ext4? Just curious for if I ever Odin back I could check to make sure back to stock rfs file system. Thanks

For those who have flashed a rom and no longer have clockwork 2.5.1.2

With some roms you need to put put 2.5.1.2 back on your phone, because having 2.5.1.2 in addition to 2.5.1.0 is kind of a hack. To get it back, do the following:

Unpack the prepare.zip to your sdcard. I just let it call the folder "prepare."

Now, open a terminal and enter:

su

remount rw

cd /sdcard/prepare/system/bin

cp recoveryfiles/recovery /system/bin/recoveryfiles/

cp recoveryres/* /system/bin/recoveryres/

cp recoveryres/images/* /system/bin/recoveryres/images/

remount ro

Now you should be able to get back into 2.5.1.2 again. When I copied the recoveryres folder on my phone, it told me that it skipped recoveryres/images, so that is why that is on another line. You can also push the files via adb if you choose.

I would like to try out the new CM6 prebeta 15.3.3 with or without ext4... When i tried to flash it like I would any other ROM (without EXT4) it would not flash.........

Then I tried to flash WITH EXT4 and failed, this is what I am doing : I got into CWM .2 installed EXT4, flashed CM6 ROM and CM6 Kernal.. It auto reboots and get stucks on Samsung logo.

I am not a total noob, I have flashed a ROM before, & got EXT4 to work.... I have Odin'd back to stock dk28 and now I am waiting for help so I can get this bad boy up and running!

Thanks any help would be greatly appreciated!
[Epic 4G Android Development] pjjohn73:
Having awful luck with ext4. I have tried several times. The process goes well. But then the phone is very laggy. Stutters on menus then jumps ahead. Games like Angry Birds stutters about every 1.5 seconds. Have tried on the Quantom and Midnight ROMs. I most recently did the simplified version that is on the Midnight OP. Still no luck. At first I thought I had an app causing problems, but just confirmed the same issues without any apps installed.

If anyone has any idea why it is so laggy, please educate me...

EDIT: I was surprised that even after going to Midnight ROM ext4 and it did not work out, I was able to go into CWM 2.5.1.2 and wipe everything and do my Mammon 1.0.4 CWM Restore. I know the kernel is ok for both files systems, but the last time I had this kernel on and did a fresh install of Mammon 1.0.4 is was all stutter like the extROMs, so surprised that the restore worked and still is running good and not only that by a Quadrant Score of 1617 which is good. Now if I could just do it on a Ext4 ROM.

Its almost as if I do any Fresh Install wether ext for or not it is laggy, by if I go to my latest backup it works. Don't make since.

[Epic 4G Android Development] Lonewuhf:
Ok. I've setup my Epic for Ext4 and it's faster than ever. Now I'm interested in overclocking the processor. How do I go about this? I've never gone into OCing yet (at least not on my phone) so I'm not sure if I can OC using the kernal here, or if I have to flash another file. Also dunno if flashing another kernal would ruin the Ext4 setup. Any help would be great!

Also, that's really high! I thought my 1650ish was high with Quantum ROM. Is that the nightly version of CM6?
[Epic 4G Android Development] DiGi760:

I tried to delete that part of the script and put those files in manually but I ended up getting stuck on the boot up screen after flashing CM and the kernel so I think I must have done it wrong.

[Epic 4G Android Development] ipaq3115:
I've been flashing back to dk28 all night.

I flash to dk28 (acs version with CWM) via odin

Then I flash prepare.zip and I get the error

If I ignore it and reboot recovery then I get to the .2 version and there are two errors, something about bitmaps missing.

Then the ext4 zip

then cyanogenmod

then the EXT4 kernel

Then I get stuck at the samsung boot logo which I'm assuming is caused by the error at line 3 in the prepare.zip

[Epic 4G Android Development] musclehead84:
why are people losing the new cwm when flashing some roms? what roms are they? thanks
[Epic 4G Android Development] DiGi760:
Because the new cwm isn't actually loaded into where the real recovery is. The reboot recovery thing is a trick to redirect to our secondary recovery which is in /system/bin/. If a rom says it supports or requires ext4, they probably included the recovery. If they didn't, you can copy the needed files from the prepare.zip and install the .2 version into other roms.

[Epic 4G Android Development] DiGi760:
@MedicStuder

Try flashing the newest midnight rom instead of the prepare.zip. It has everything baked into it that the prepare.zip did. From there you should be able to run the .bat file and convert to ext-4. The midnight rom also has both rfs and ext4 support and will work with either file system.
[Epic 4G Android Development] MedicStuder:
I think i got it know. I again odin dk28 then followed the steps in the youtube video and ignored the errors and installed midNIGHT ROM and it appears that the EXT4 installed correct and the ROM is running great.

[Epic 4G Android Development] thomasskull666:
I'm trying this out as well, and I can't get the phone to be picked up by ADB when in CWM. I never have been able to, it would be handy and I think that is the only way to get this to work. I haven't successfully seen the "2.5.2.1" yet, which isn't a good sign lol.
[Epic 4G Android Development] sniperkill:
For some reason, I dont think your supposed to run the .bat file while your in cwm. I think your supposed to reboot your phone, make sure you have usb debugging enabled, and run it from there, but I've found that you have to have adb.exe files installed where ever you have the whole ext4 downloaded at. I downloaded it to my desktop, and the run2.bat file wouldnt run until I put adb.exe files on my desktop.. But even after that, it still failed when I ran the run2.bat file. Dameon started, and it seen my phone, but it kept saying cannot stat, like, everything it tried to do.... So, imma wait it out til Dameon87 can shed some light on this for us...
[Epic 4G Android Development] thomasskull666:
I know all this, I just couldn't even get the phone to connect to my comp when in CWM. I got it working now, but when I reboot into recovery after flashing prepare.zip either by using adb reboot recovery or by selecting advanced/reboot recovery, it hangs on the Samsung logo screen. Not sure why, I've tried to reflash recovery again with the 2.5.5 one click and still it's a no go. Any tips?
[Epic 4G Android Development] sniperkill:
In order for you to see recovery 2.5.1.2 at the top, you put the 2 .zip files on your sdcard, boot into recovery using adb, then grab your phone and navigate to the prepare.zip file and flash it with cwm. Even tho IT WILL fail, after it tries flashing it, once you reboot into cwm, it will say 2.5.1.2 at the top....
[Epic 4G Android Development] sniperkill:
OOOHHHH, my bad. I misunderstood you... Can you get into download mode? If so, try flashing DK28

[Epic 4G Android Development] thomasskull666:
Lol it didn't fail, it flashed fine. Just still won't let me reboot into recovery, I can boot into recovery from pressing the 4 hardware buttons (and it still says 2.5.1.0) but it will just stay at the samsung logo screen if I use adb.
[Epic 4G Android Development] sniperkill:
lol, glad to hear you got it working.. As for the other guy's question, I dont think anyone besides the OP got it to work yet... imma have to try again tomorrow, the wife's getting pissed that im still up, lol.... Good luck
[Epic 4G Android Development] thomasskull666:
Lol I think you misread my post, I'm still not able to reboot into recovery after flashing the prepare.zip. It hangs on the Samsung screen if I use any other method to reboot into recovery other than pressing the 4 buttons, directly after flashing the .zip. Baffling.
[Epic 4G Android Development] hayabusa1300cc:
I can add that at first I had adb in cwm and ran the .bat

Nope. I just ripped apart the 2.5.5 root and recovery one click and implemented the first part of this into it. Now I am in 2.5.1.2 cwm, we'll see where it goes from here.

Unknown Volume Errors

When I boot into recovery, in addition to the orange menu, I also get several lines of white error text. It mostly consists of "unknown volume" errors.

E:unknown volume for path [/data]
E:unknown volume for path [/cache]

There are also errors about not being able to mount and open the folders that would be under those paths.

Out of the box > odin > ext pit and pda files. Only have auto reboot and partiion checked. when it's done, pass, I let it finalize it's bootup. Then I shutdown. When its off I boot to clockwork and let it do it's thing, then flash bonsai 4.01. I done this several different ways with same lockup issue. I've tried not flashing bonsai and just letting it boot.

Are there any benchmarks to prove

"ext2 would be a) faster and b) less damaging (no double writes due to log) to the flash."

If this was true why is every major ROM on the market using ext4 when ext2 is so readily available?

This is a sincere question and not a slam...I am uninformed.
[Epic 4G Android Development] ZenInsight:
Great question. You are asking if a nandroid Data restore (only) from a RFS backup will work once ext4 is installed. Excellent question.
