Question about ext4 - Epic 4G General

So I was wondering if the ext4 only works with roms or how can I get it to work with my stock rom that's rooted. I like the stock two launcher with the dk28 and I want to keep it like that. Thanks for your help in advance

Most ROMS will indicate if they have ext4 support or not. Read the release notes and see if they mention ext4. If they mention ext4 in the title, they do support it. If in doubt, post a question about it in the thread to ask the developer if they do and if not, if/when will they get it.
To get ext4, just use Daemon's CWM3 method to upgrade to ext4 and then flash an ext4 ROM.

Follow the instructions in the ext4 thread to convert to ext4. Then, flash your dk28 from clockwork, followed immediately by flashing a kernel that supports ext4.

Ok thanks for your help ill try that

Just remember to flash the kernel after the rom and before you reboot the phone and you'll be fine.
The kernel may only be available with the older amend scripts so you may need to use clockwork 2.5.1.0 and 2.5.1.2 to flash it.
Make sure you have the recovery redirector installed. If you have run the one-click root and recovery v2.5.5, then you have it.
Get the the one click ext4 from this thread. It says this method is deprecated, but it works just the same. Read the instructions before you do anything with it. Get the dual file system kernel from this thread.. And you can use noobnl's pre-rooted and redirected DK28 from this thread.
Since you are still on DK28, I would flash the prepare.zip, reboot to 2.5.1.2, run the one-click .bat file, flash dk28, flash the kernel, and tTHEN reboot. Then you will probably need to either reinstall cwm 2.5.1.2 (using the prepare.zip) or go ahead and install cwm 3. It sounds complicated, but it isn't that bad. Waiting for everything is the worst part.

Yes the rom has to be ext4 compatable. Make sure you flash the kernel after the rom.

i assume you mean ClockWorkMod recovery.....
Root the phone...Download ROM Manager....open the app and flash ClockworkMod Recovery...reboot into recovery...if it takes you to the stock 2e recovery...hit re-install packages and it should take u to CWM recovery

which rom? i'm assuming you're using an ODIN'd 2.2 rom, and if so, you need to use SuperOneClick to get root, then mount system as rewriteable, and then push untermensch's modded 3e recovery so that you can use CWM with a 2.2 rom.
OR
You can dl one of the voodoo kernels, making sure you have the required voodoo disable key file on your sdcard, and flash the voodoo kernel using ODIN. (which is WAY easier in my opinion)

Cwm3 question

so I already have nebula rom with ext4 and cwm2.5.1.2 and a lot of new roms say they need cwm3 to flash them is there a way to get cwm3 without having to flash back to stock and do the new 1 click root? Thanks for your input in advanced
Sent from my SPH-D700 using XDA App
I just used the new one click root that installs the new cwm to get it installed onto my phone.Then if your not converted to ext4 yet just boot into cwm and it will convert over all the file systems to ext4.

Looking for ClockworkMod 2.5.1.2 to flash over 2.5.1.0. Just can't seem to find it.

A link or a file, either would be great. I keep finding CW 3.x and 2.5.1.0, but never 2.5.1.2 for Epic. Please, someone point the way.
Many thanks.
To get to .2 boot into clockwork go to advanced and reboot recovery. That should put you into .2
Sent from my SPH-D700 using XDA App
This thread is where you need to go. Get the one-click ext4 zip. Inside it is a file called prepare.zip. Flash prepare.zip to add 2.5.1.2 to your phone if the rom you have doesn't already have it. Then, if you death-grip into recovery, you will see 2.5.1.0. Select advanced->reboot recovery to reboot into 2.5.1.2.
Thank you guys. I do need to flash since I never have flashed 2.5.1.2 prior.
I also found a similar file inside the viper 4.0.2b ROM package.
Follow up question, inside the flash, in addition to the recovery files, I see:
/system/etc/mke2fs.conf
/modules/ext4.ko
/modules/jbd2.ko
I presume these are for ext4. I plan to stay with RFS for now. I was looking for 2.5.1.2 because I want to use the latest Bonsai ROM (coming from stock DK28) and it seems to call for it, even with RFS. Will these extra files cause any issues later?
Thanks again.
I don't think that is going to work with Bonsai! 2.0.0 or > howeverif it does work please post your results in the bonsai4all thread

Thanks for pointing this out. I mis-read the post. In the original post, while beneath the "Latest News", it is written that RFS not supported in V2.0, immediately below that, under "Next Release News", it is written that "No more RFS...". Based on "Next Release", I thought it would be the version after the current. That, along with the instructions on the second post for RFS, I falsely figured...
I guess it's all for not.
I am stuck at SAMSUNG anyhow (after Reboot Recovery from 2.5.1.0). Can't get to 2.5.1.2...
Edit: On the Stuck on SAMSUNG issue, I re-flashed the latest 1-click from HERE, then re-flashed the .2 prepare/flash first .zip, and all is good. I can get into .2 now.
So the big question is whether you can create a swap disk with 2.5.1.2?
Sent from my SPH-D700 using Tapatalk
I flashed 2.0.1 with no problem using 2.5.1.2 but i was already converted to ext4. Flashing it would put you on ext4 and add cwm3
now that I know how to update it to 2.5.1.2 my question is-
should I?
I have no real reason to do so. I don't intend to do any further modifications to my ROM, just going to stick with the pre-rooted 2.2 I have. Would there be any benefit to updating CWM in this case?
The only reason to get 2.5.1.2 was to be able to flash to ext4. And then cwm 3 simplified the conversion to ext4. If you don't intend to convert to ext4, then there is no reason to get anything other than 2.5.1.0.

It adds ext4 and negates the need for cwm3 iirc.

Odin? Then, restore a backup once your back on stock RFS (assuming you don't want to lose anything. Otherwise, don't restore.
Also, you might have gotten a bad download

thanks can u walk me through this a bit its been a while. How do i odin back to eco5 and keep root? i have everything i need. I guessi just need to odin to eco5 and convert to ext4?
If you're on RFS trying to install an EXT4 ROM, it won't run because of the edify script. Best bet is to either convert to EXT4 or find an RFS ROM... First you'll have to Odin of course, but after that, aim for either RFS-EXT4 capable ROMs or you'll have to choose which one. Also, I don't really know about his ROM's that much, but is it EC05 or newer?
eco5 at this point i just want to get back to stock eco5 and get root

You wont be able to keep root. You'll have to Odin back, then re-root your phone. It's a process, but it's what'll have to be done. It'll take maybe 10 minutes total. Just search the dev section for Odin, and follow the directions.
Here's the link... Just follow the instructions.

Thanks dude your a lifesaver. So once I get that part done I need to root. My apps im not worried about I have titanium backup and a nandroid backup through rom manager. never used it after somthing like this though so what is the next step after I odin to eco5?
After you Odin, run the new root with the new cwm so you're completely up to date... then you will have root and recovery, and you just flash a ROM, or a backup ...just make sure it's EC05 and RFS or you'll have the same issues.
hmmm.....do u have a link by any chance? also when I 1st start this up how long should I wait for this to start? any ideai oh how to use rom manager of titanium back up comes into play with this?
You got asserts error because you used ROM Manager. If you download the EB13 stock tar from Bonsai site, use Masterkey unlocker on that, then power down, 3 finger into recovery and flash 4.1.3, Boot up, power down, 3 finger, Advance Restore Data you will be fine. Stay away from Rom Manager and Quick boot for backup, restore or flashing.
Look at the sticky posts in the dev section. You're looking for 3.1.0.1 one click root. Download and run that. And yes, don't use ROM manager. Just power off and use volume down+ camera+ power to boot into clockwork mod.

Rooted my GF's Fascinate, Need Help Nandroiding

I just rooted my girlfriend's year old fascinate that was bone stock from day 1. In CWM I am unable to make a nandroid (I get an error). I've heard I need a modded stock kernel in order to successfully make a backup in CWM 3.x or something along those lines.
I looked in the developer forum under the sticky with the list of everything, but it only shows three or so kernels (none of which hint at stock).
I have a Thunderbolt and before that a Droid 2 so I know a lot about rooting and flashing with those two devices, but I am new to the Fascinate. I messed around a bit with Odin when I rooted the phone, but I'm still learning.
Any help is greatly appreciated.
Older recoveries supported amend scripting (2.x.x) while newer ones support edify scripting (3.x.x)...depending on which rom your running it may cause problems with backups and restores if you don't have the right recovery...unless you plan on going to an Mtd build (cm7, Miui, ect) I would recommend using the (2.5.1) recovery also called the 3/30 fix all recovery because this version supports both amend and edify scripting..so you make a nandroid with out issues....if you can get to recovery still I would install this zip and then select reboot recovery...it will bring you to the 3/30 fix all recovery where you should be able to backup and restore your nandroid...link to follow shortly...
Scroll down in the first page to the .zip file, download and continue with the steps I listed...I know its confusing at first mainly because development has happens rather quickly which is a good thing! its just a lot to catch up on!

What would you recommend if my plan was to install MIUI or OMFGB?
I'm deciding between those two because I use OMFGB on my Thunderbolt all the time, but MIUI is very good for my girlfriend I think because it's very straight forward and simplistic.

Its not hard to get in to these roms, but you must be sure if you have problems or want to go to anything non Mtd you will have to Odin an official VZW tar and pit file to repartition before going to any non Mtd rom

So basically:
1. Flash the CWM you posted in your original reply
2. Nandroid her current stock setup
3. Flash MIUI
4. If I ever want to return to stock or a non-mtd rom I have to do what's posted in your second reply?
If all that is correct please let me know. Also lets say she doesn't like MIUI, can I simply flash that nandroid or will I have to do what's posted in the second reply?
When I try to flash that older CWM in CWM I get this message:

Yes you will have to do what's in the second reply.
You have it all correct, if you nandroid her current stock setup you can only restore it on a non Mtd build you would have to do what I linked to in the second post to use a vzw rom with pit file to repartition...boot fully, flash recovery then you could restore her stock nandroid..for example you get her on Miui you can only do a nandroid with the recovery that comes with it...I think its a 4.x.x recovery...trying to restore the stock nandroid before repartitioning back to stock will cause problems...so basically you only want to restore a nandroid on the same build (Mtd to Mtd nandroid, or ext4/rfs to ext4/rfs nandroid) and if all else fails and you run into big problems, doing the VZW restore (although can be a lengthy process) will get the phone back running to start over!

I did see it after I replied, is her phone on ed05? I'm surprised that neither the 3/30 fix all or 3.x.x is working
Edit after looking at the pick again you're using times infinity's recovery....you would need to Odin the 3/30 fix all recovery and immediately three finger boot into recovery without letting the phone boot or if you installed the 3/30 fix all via .zip file, you need to choose reboot recovery to enter the fix all one, it should be 2.5.1 I believe

Here's a picture of her phone info:

And as you can tell from the other photo, both making a backup and flashing the CWM 2.x doesn't work.
Trying a backup results in: "Error while backing up boot image!"
Trying to flash CWM 2.x results in that long information message.
That sucks man i'm sorry I've never been on ed05 so I don't know if that why your having problems my suggestion...back up all her contacts by exporting them to sd card, download titanium backup its free in the market, backup all of her apps and screw the nandroid, flash what you want, restore her apps with titanium, but do not restore data, restore get contacts and then boot into the recovery that comes with the rom/kernel and then do a nandroid and that WILL work..again sorry for the trouble, just trying to help.

I appreciate all your help. I'll let you know how it goes.
ed05 is not the problem...You have to use cwm 2.5.1.x if your trying to nandroid backup a stock rom. This version of cwm works on all froyo roms and powerwashed gingerbread. After you make a nandroid with cwm2.5.1.x, then flash cwm4 and proceed to installing miui.
Read this link for flashing mtd based roms such as miui, cm7, vgb...etc

That was my first reply to him...to use 2.5.1 but he said he still got errors? I don't have a clue what the problem is...he's said he's used ti's 3x.x, and the 3/30 fix all still with errors? confused?

If not you need to:

make a nandroid back up of the stock rom.
go back to odin and flash the jt's cwm4
boot into recovery
wipe data, cache, dalvik
install miui.zipfrom sd card
Follow the rest of the directions in the link I provided
+1 there ya go. Beat me to it.
Plus, I wouldn't even worry about backing up your stock ROM. Just flash the full official package. This will wipe your slate clean if you run into problems. Restoring nandroid backups leads to glitches eventually from what I've seen.
Sorry, I didn't see there was a second page here...I'm a bum.
