This has been updated to be deodexed+root+busybox only (though it still supports JAC kernel out of the box). At this point there are so many different lag fixes that it's hard to keep up with them all.
What it does have:
ROOT
No .odex files (deodexed)
Newest Busybox
ext manipulation files and libs, so it makes it easier to e2fsck or tune2fsck if you want ext4.
Also thanks to eugene373 for his work in establishing a baseline update.zip without which this would have taken a great deal more work.
Should work in clockwork, doesn't seem to need a wipe. If you have problems, use regular recovery, just rename it to "update.zip" on the root of your sdcard and it should flash just fine.
WARNING:
This should be completely safe. Nonetheless, should loss of job/loss of fertility/nuclear war ensue, I am not responsible.
Instructions:
1. Load the .zip file onto the root of your internal SD card (/sdcard)
2. Using Clockwork recovery, do "Install zip from SD card", then "Choose zip from sdcard", choose the VibrantDeodexed.zip, and choose "Yes"
2b.(ONLY If you don't have Clockwork) rename the download to "update.zip" and place it on the root of your sdcard. Then reboot into recovery and choose "Update packages".
3. (Optional) Flash JAC's kernel with ODIN using the directions specified HERE It is more stable and gets better benchmarks but there do seem to be some issues with the screen taking a while to wake up.
http://www.getyourboneon.com/VibrantDeodexed1_2.zip
NOTE: The first boot takes a long time because it has to dexopt stuff.
Version 1.0:
Just stock and rooted w/busybox
Version 1.1:
Uses the latest version of busybox and comes with support for JAC kernel out of the box (no need to flash the init.d update.zip and supersedes my method if his kernel is flashed.)
Version 1.2:
Updated busybox, added ext tools. Removed all lag fixes, though it will still work with the JAC kernels.
There are so many lag fixes out there at the moment that I didn't want to "lock in" people to a particular one.

what is the ext hack? and how does it make the phone faster?
the ext hack puts the data and dalvik cache on the sdcard on an ext2/3 partition...
it brought my quadrant score from 850-950 up to 1400-1500
its like apps2sd but the apps part is still on the phones internal memory...
original link is here for the hack--http://forum.xda-developers.com/showthread.php?t=739647
anomalous, thanks for all your hard work...
so if we get a good deodexed rom, someone could compile JIT for our 2.1 right?

why does the phone run faster with the data stored externaly? or is it because of the partition type?
im not quite sure, I would have figured our internal mem had a faster transfer rate than an sdcard, but Im on a class 2 and still getting better results... so it cant be a faster transfer rate...
@freedom: put simply, EXT formats run way faster than Fat32, which is what the rest of the storage is.
wiki: EXT3 (common format) and ext4 (latest)
edit: better explanation here
However, I'd most love to see either one of the internal storage (app storage or the other internal) finding a way to be put into EXT3, as that would probably run better than any sdcard.
Just so everyone Knows, the Format via the update script don't work, still trying to find the correct command for it....
But, in clockworkmod, just format the system / data / cache partition's before flashing.

Er, the internal storage is "rfs", samsung's proprietary fs. (And the read/write speed of fat32 tends to be a little faster than ext2, and TONS faster than ext3/4 - journals slow it down in exchange for stability after crashes)
The increase in speed is just that - faster underlying hardware. The onboard "sd card" (same "disk" that /data is partitioned out of) is heartbreakingly slow.

Is there an app to test thr transfer speed on the phone? I ask because I have moved my data/dalvik to ext3 on a class 6 sd card. When I benchmark reads from Linux the speed and seek time between internal and my sd are not that great yet the actual performance of the phone is as different as night and day.
I wonder if this is more an issue with the rfs implementation than a hardware speed issue. My other thought is that maybe the benefit comes from having a separate I/O lane for loading data/dalvik. Not sure the hardware actually supports multiple/parallel I/O but it's a theory.

I'll see what I can do to test it out this afternoon. (If you want to jump the gun, what I'm figuring is finding a static-linked arm version of bonnie++ or similar. Booting recovery, mount data or sdcard - not both - and test. Reboot recovery, test the other one. Maybe test dbdata and external sd as well, but the interesting numbers will be the first two - onboard-with-rfs and onboard-with-vfat..)

Honestly, used the ROM kitchen for most of it; it uses a brute-force approach to sort out dependencies. Only one I had to do manually was TouchWizCalendar.apk (because it needed both twframework.jar and com.google.android.maps.jar). I'll work on getting the update script working during work later today.

Which ROM kitchen? I used my own script. Does the ROM boot up and run doing it that way? Should be interesting to play with.
Hmm, got the update script working almost perfect, but now it causes crashes. Seems to be missing dbus.conf.
OP updated - it works.
I did something very noobish.
I formatted the cache, system and data and forgot to throw the update.zip file onto the internal sd card prior to doing this. I can get into the stock recovery but as far as rebooting the phone to put the update on the internal storage I can't do that. I am able to take out the 2g memory (avatar) and load the update.zip on there but, of course, the stock recovery won't recognize that.
Is there a way to put the update.zip onto the internal memory in the position that I am in? Is there anything I can do?
I think I just made a HUGE no-no.
Any help would be greatly appreciated.

Hi there,
I've seen all the posts about formatting the sd card with the ext3 filesystem, but i would like to know if there is a way to modify the root filesystem to be ext as well?
I know this is probably a daunting task, but im willing to learn and want to jump into android headfirst. Any suggestions would be appreciated. Thanks!

That's basically what Voodoo does, except it uses ext4 not 3. No such thing yet for Froyo unfortunately.
Well this may be OCD of me , but I like knowing the file system isn't some virtual filesystem. I'm still learning advantages and disadvantages of different file systems, but I know that FAT (or RFS) is horrible.
It sounds like I'd need to write my own ext4 driver, flash a kernel with that driver, make a partition on the main 1GB internal memory as ext4, and install the ROM over that. Am I missing anything, or does that sound right? And if that is right, are there resources on how to do that task?
Thanks so much, everyone!

first of all, you need to start out with source for 2.2, which is not available yet....so everything else is pretty much not going to happen until source is available. there are couple of 2.1 kernels that have already been built and they work pretty well.
**EDIT**
and source has been released for the i9000. we are close now
These patches add ext4 support for your sdcard (in the Nexus S - the internal card.) There are a number of reasons you might want to do this - performance (ext4 is faster, plus mounting ext4 is basically instantaneous, which is very nice on reboots...no more checking sdcard), it's more efficient, you get a bunch of file system security features (if you care...)
You should not apply them if you don't really know what you are doing. The patches are resonably benign. Converting your sdcard partition to ext4 is NOT NOT NOT benign and you can really hose yourself doing it.
I'm not going into great depth with these instructions. If you don't understand them, play around with building cyanogen, installing it, etc until they are crystal clear.
To swap your sdcard to ext4:
* Apply the patches and rebuild cyanogen. Rebuild it. They will change your recovery image and vold.
* Install vold and flash (and/or boot) the recovery image.
* Boot into recovery, mount your sdcard and back it up to your computer (i.e., not nandroid, copy the files.) Nandroid would be a good idea too.
* Format your media partition to ext4 (the one that is vfat, by-name is media, mine is partition 3) mkfs.ext4 can be found by googling, or you can use make_ext4fs from /system/bin. I used mkfs.ext4.
* You should be able to manually mount that.
* Push your files back.
* sync and reboot.
Et Voila, you should have an ext4 sdcard partition.
THIS IS VERY DANGEROUS.
YOU CAN REALLY HOSE YOURSELF DOING IT.
Here are the patches:
http://review.cyanogenmod.com/#change,1705
This one adds ext4 support to vold, thus allowing gingerbread to mount ext4 partitions for the sdcard (which on the Nexus S, is the 'media' partition.)
and:
http://review.cyanogenmod.com/#change,1716
This is a change to recovery, making it seamlessly mount ext4 partitions for /sdcard.
Code:
# mount
/dev/block/platform/s3c-sdhci.0/by-name/system on /system type ext4 (ro,noatime,barrier=1,data=ordered,noauto_da_alloc)
/dev/block/platform/s3c-sdhci.0/by-name/userdata on /data type ext4 (rw,nosuid,nodev,noatime,barrier=0,data=ordered)
[b]/dev/block/vold/179:3 on /mnt/sdcard type ext4 (rw,nosuid,nodev,noexec,noatime,barrier=1,data=ordered,noauto_da_alloc)[/b]
/dev/block/vold/179:3 on /mnt/secure/asec type ext4 (rw,nosuid,nodev,noexec,noatime,barrier=1,data=ordered,noauto_da_alloc)
tmpfs on /mnt/sdcard/.android_secure type tmpfs (ro,relatime,size=0k,mode=000)
....and if you turn on USB Storage, the sdcard shows up as an ext4 disk...
As expected, but this is going to be one for the Linux geeks.
Wow, it is VERY nice to have that sdcard mount instantly on boot. VERY nice.
oh the read/write speeds
If anyone is interested in playing with this, I submitted the change to cyanogen:
http://review.cyanogenmod.com/#change,1705
The tricky bit is getting the filesystem created. You can use:
/system/bin/make_ext4fs.
That leaves me with a recovery which will not currently mount sdcard as ext4 unless I fiddle with fstab and mount it myself. On to look at that.
...and, here's a patch to the recovery which will let it mount /sdcard as either ext4 or vfat, making this change reasonably seamless.

i would love to see a Quadrant or a benchmark after this
this is and awesome hack to use with App 2 SD
it'll be lag less
the only annoyance, is that if you want to MOUNT USB on a Windows PC, then you'll need a software to read EXT4
for anyone interested this will be handy
http://www.ext2fsd.com/?page_id=16
i'll definitely be doing this MOD, as i'll be running anything i can from the Internal SD
So this will only work on CM7?
Please some of the genius here may post a step-by-step tutorial or howto for this one? It will be very apreciated.
No, it will work with any build, but you need to rebuild vold in order to get it to mount. The easiest way to get them outside of the CM tree would be to build cm and then copy the vold out and use that. It should work with any ROM.
The latest versions - which are in CM's gerrit - include modifications to the sdcard utility to use fuse to mount the filesystem using FAT semantics (i.e. - bypass security). Frankly, this is a waste. It slows everything down, noticeably, and app problems are few and easily fixed if you know how to fire off a chmod.
I haven't provided step by step instructions since it can seriously hose your phone if you don't know what you are doing.

If done right this would increase the read/write speeds. For example, your boot up time would be much faster and ext4 is more effecient. So it's not a waste but it has to be done correctly otherwise is could do more damage than good
Using the version I posted to CM gerrit, which bounces the file system through fuse and mimics FAT security, is still better than FAT (IMO), but it's not nearly as fast as just mounting the filesystem as Ext4 - though it is more compatible.
I've been running mine mounted as straight ext4 for a couple of weeks. Probably the single best mod I've made to any of my phones. There are occasional app bits that I need to fix manually (such Dropbox resetting file ownership), but it's worth it for the quicker boot up and faster overall operation.
Here you find the ROM CyanogenMod 7 compiled for Nexus One with ext4 sdcard mount support:
- https://github.com/diegostamigni/nexus/tree/master/one
Is the only reason to pipe it through fuse to get it to mount on m$? If so I'm not going to bother - I only use linux almost exclusively these days

I bought new SD card i want to wipe my phone completely and install Darkys Rom. I formated my new SD card to ext2 in Ubuntu but my phone didn't recognize the file system. Then i used Clockwork to format my (external) SD card and what i did i formated my internal SD card. I'm completely failed. Can somebody give me step by step tutorial how to format external SD Card to ext2 or ext4. Also i would like to know if i will be able to copy data under windows when the phone is connected through USB.
Thank you
Sorry for my English
Hi! Please tell me why do you want to format your SD card to ext2 or ext4? There is no need for that. Just format it tu FAT and that's it. If you want to apply lagfix then do it under recovery with the lagfix option under advanced features.

how do I format my external SD card to ext2? I have Samsung Captivate. I got Cygwin, since I use Windows. Does anyone know what commands to type in cygwin?
I want to put files larger than 4GB on my card as well.
I think this will be useful for a lot of people.
I found a thread http://android.modaco.com/content/h...an-i-bind-mount-e-g-system-sd-xxx-sdcard-xxx/
But I am a noob in Linux, and it would be GREAT to have step by step commands I would have to type in to format my external SD card, while its in the phone, etc
Possible problem I see is that the phone might not recognize external card if its ext2/3/4 . We might have to have small FAT32 partition on there as well? Or may be Froyo has that ability...
I'm looking into doing this myself, in my case so I can use symlinks to copy apps "data" folders (not the "data" partition, but the folders in /mnt/sdcard where apps put different things) onto the larger, external sdcard. It seems like it could be possible, just need to make sure the /etc/fstab file is updated properly, and of course make sure your kernel has the ext2 and/or ext4 modules loaded and running (which you probably will if you have a lagfix installed). I will play with this and post back my results here...
I have been looking for this myself for a while aswell, but on 4 different kernels and CWM v2.5 and CWM v3.0, I couldn't find any option on how to change the ext. SD to Ext4. If anyone knows how to then please post it here!

So, progress report...
Still no success in this matter, although I have learnt a bit today about Android's internal workings. After backing up my system with CWR, I first tried formatting my ext sd card with gparted on my computer. Bad choice... Even though no config files were stored in it as far as I could tell, Android "panicked" and decided to restore all my configs to default, severely crippling my system and making a lot of apps force close when I restarted the phone.
At that point I thought, since it is now broken, might as well play with it So the next thing I tried was formatting my internal sd card (only the vfat partition that gets mounted in /mnt/sdcard) to ext2, but this time using the "busybox mke2fs" command, on the terminal emulator on the phone. This seemed to be successful, and I could read and write to the new ext2 partition, although for some reason, I got the feeling that apps kept resetting their settings (not sure what caused this, didn't really looked into it much). So once that was up and running, I decided to modify the /etc/fstab file, like I would do in a normal linux environment, to automount this partition on boot, as ext2.
At this point I rebooted the phone, but hmm... Android converted the partition back to vfat. Not good. This leads me to believe there must be some kind of "recovery" commands run on startup, in case the system detects the partition is not the default file system, or something along the lines of that. At this point it got kinda late, so I decided to document my progress, restore (which thankfully left my phone the way it was at the beginning of the day) and call it a day.
So, things that I still need to find out:
1) How does the system convert the partition back to vfat on startup and how could I avoid it from doing it? Maybe by having a small vfat partition to fool it into thinking all is good and normal?
2) When I had my partition as ext2, I couldn't see it on my computer when connected via USB (I'm on a linux system so the fs being ext2 is not a problem). Wonder why...
3) If I had a small vfat partition, how would I go about mounting the ext2 partition on the same mount point after the system checks the vfat one? Maybe by binding it? Gotta look into that as well.
4) Finally, have to check why the apps couldn't maintain their settings after a certain amount of time (for example, if I opened terminal emulator and changed the colors, these would stay if I closed and opened the app again right away, but if I closed it for a while, say half an hour, and opened again, it would be back to default...)
I'm on a Galaxy S btw. If anyone has any insight on any of these matters, would be much appreciated!
Any progress? Would really like to use +4 GB files.

Not true, read the rest of the thread before u post! Its not a hardware limitation, its because Android uses fat32 as filesystem.

I have ext2 on my external 32GB SDCard, just formatted it on my PC and put it in the phone, working without any problems. I just watched a full length 720p movie with DTS sound on my phone without having to re-encode the mkv
I'm using CM7.1 on my phone which auto-mounts the SDCard even with ext2. It won't work on stock ROM, but any kernel that has ext2 support should be able to read ext2-formatted cards but they might not auto-mount the sdcard.
On my PC I had to install a ext2 file system driver (google ext2fsd) for Win7 to be able to read the card when attaching the phone to the PC.
Hi there,
Is there a way to make the add the internal SD card to the main memmory? So that there would not be an internal SD card anymore?
I do not mean swapping the moutpoints around so my External_SD becomes my primary and my internal my second....
I want to get rid of the internal one alltogether (adding it to main memory).
I figure that I'll have to format the storage in a certain way... would that do it?
Can someone tell me step by step what to do?
I do have CW-mod installed.
I did search the forum, but couldnt find anything conclusive. Just hints that it should be possible...
If there already is a thread where all this is explained, please point me to it, because I couldn't find it.
Thanks,
Pfeffa-rah
I don't think this is possible , never heard of someone who did it
I have no idea how to do that. My question is... why would you want to do that?
Having an internal_sd partition adds the benefit of having big app data (such as those in Gameloft games) sit in a very fast partition and still be called "sddata".
Also, it's mountable via PC so everything in there can still be backed up. So it's best of both worlds really.
This was discussed some time ago in this thread: http://forum.xda-developers.com/showthread.php?t=1013575
There were ideas on how to remount the cards at boot. I myself come to the conclusion that since more phones start to behave in this way, app developers will have to start dealing with it. It just sucks they are mostly slow on the uptake. My main problem was the Spotify cache location being hard coded so I resorted to hack the Spotify apk.

That was actually an honest question.
I wanted to understand why he wanted to do it. (i.e. What would be the advantages of it.) There was no supposed sarcasm in there.
how about the ability to install 5x more applications?
Having that stupid 5gb partition as sd card and the real sd card as a sub folder is retarded...
My 32GB class 10 cars is a lot faster than the internal one.
The internal 5gb memory is MUCH TOO SMALL!!! Most apps don't allow you to store data on the external card. If you like me and many others install some games that download aditional data + a nav app that downloads maps for europe + some streaming music app like wimp that can cache music for offline play then you are ****ed with LG's setup.
The setup CM7 uses solves the main problem but effectively wastes the 5gb by mounting it at emmc where like 0,0001% of apps are able to access it.
So adding those otherwise wasted 5gb to the main memory would be great. But i have not seen any solution to that yet :-(
Thank you Gensplejs for explaining that to them. I had no idea how to reply to that since it seemed so obvious to me.
This thread was ment to be a question about how to do it and not to discuss the usefullness of it. That is where I lost the way in other threads...
So, thanks for your replys all (realy).
But now, back On-Topic:
How would I do it?
Sent from my LG-P990 using XDA Premium App
Please don't blame me if you tried it and you screwed up your phone.. It's your choice...
Well, I don't know if this would work, but this is how I would do it (accepting the fact that I'd loose almost 2GB of /data's free space):
1. Format your internal sd card to the same file system as your /data partition is (ext3 or ext4)
2. Copy every file from /data 1:1 to your sdcard (cp -R /data/* /sdcard)
3. I don't know when and where the partitions are mounted (maybe init.rc??)...anyways change the target there and let /data point to the internal sd card partition (so it is ensured that it is mounted automatically to the new location)
4. Reboot and keep your fingers crossed
I think i figured how to do it in theory. First we need some free space at our microsd to cp /data. Then we should repartition with fdisk /dev/block/mmcblk0p8 and p9 into one partition and change vold.fstab to mount only externalsd at /sdcard as we do when we swap partitions. In theory it should work but i cant test it right now or make a script since ve gone vacations and i dont have a pc to restore in case of error
I agree.. certain apps wont store to sdcard.. its better to use the whole 8gb as phone storage, and use external sdcard as default sdcard.

What ive found till now is that sd swapping is easy. You can do it by tweaking only vold.fstab. But repatriationing is a pain in the ass. Looks like lg has "faulty" partitions or something and to do it you must mesh up with with almost half partitions.
I had to rebuilt boot lgdrm recovery data and sdcard to make em half work. So it probably isnt worth the trouble. Also I think init.rc is built on the boot. So just remounting internal sd to /data wont work either.
sectors is not space
it says 7996, so thats 8GB
i saw it in hurry. the brain sometimes belives whats he want to belive
sorry
New to XDA
Hello everybody,
I'm new to android and i'm trying to find out how to solve the problem posted in this thread.
I see you've got the awnser but i don't know how to do this.
I've been searching google and XDA for ever but i just can't find the awnser.
Could you make a step by step howto or point out to a post how to do this.
I mean converting your external sd to ext4 and change the mounting points.
I'm a complete nood, i didn't get adb to work on my pc, ext4 recovery is not for the p990 2x.
I've read something abbout changing fstap for swapping te mounting points for sdcard and emmc, witch is also ok for me, but formating to ext4... wel i frankly don't know how to do this.
I'm quite stuk on this.
The only partitioning experience i've got is Gparted in Ubuntu or repartitioning in Windows 7.
Thans in andvance!
Greetz,
JMG

check this
you can expand data partition , but there is a limitation of 1.75gb
Thanks davjan
Thanks davjan,
As far i can see it's indeed not worth it.
I wil have to go on and try to find out how to change the filesystem to ext4 and swap the internal and external sd.
That way i get more usable space instead of a big datastorage witch cannot contain program data.
But thanks for the quick reply.

what rom are you using? is your phone rooted?
swapping internal with internal sd is very easy
and most of the roms here on xda are ext4 , if you instal one of them they autoconvert to ext4

I you read the link provided you'll see that it makes what you want: grow internal filesystem = lower SDcard usable space. The only thing is that it doesn't seem possible is to use the whole space: system limitation. 75Markus tried high /system and /data values and phone didn't work.
See in his Mediafire Folder, 'Nvflash + guide for changing Partitions:
http://www.mediafire.com/75markus
Ext4 is now common with custom ROMs (in fact all of them).
You should search in sd-ext partition system, which was designed to artificially expand filesystem on older phones using an 'ext' partition. I didn't heard anybody using this on O2X.
If you use CyanogenMod based ROMs, your external card will be mounted ad /sdcard by default.
Switching internal and external SD
Thanks guy's,
I'll check it out.
I've been using cyanogenmod 7.1 stable with vorkkernel 20110208.
But that gave me batterydrains while using maps and nextvid ate the same time (while i'm driving).
Now i'm trying MIUI 1.11.11 with latest swift extreme.
But MIUI is very buggy so i'm thinking of going back to CM.
The only thing is that my phone won't boot with the latest vorkkernel.
