How can resize that system.ext2 size????

How can resize that system.ext2 size????

check out this thread http://forum.xda-developers.com/showthread.php?t=774254
you will need to install ubuntu (or a linux distro)
You will need to mount the orginal ext2 copy out the contents from that into a new folder then recreate the new ext2 using the genext2fs command and setting the size to somthing bigger. the suggest size in the post is 307200 (which equates to 300MB)
Hope this helps

you can also dd extra space to the end of the filesystem..
something like .
dd if=/dev/zero bs=1M count=X >> system.ext2
count=5 would add 5mb
edit forgot after you dd you have to run resize2fs system.ext2 to resize the filesystem.

dd stands for duplicate disc. it is a command that is used in a linux terminal.
If you want to use it then
a) you will need to install a linux distro (e.g. ubuntu) and
b)read this http://www.debianhelp.co.uk/commands.htm as it might help explain a bit more

Lag Fix for Galaxy S "Showcase"

I'm sorry to post this in the Fascinate forum, but as you all know Cellular South's version the "Showcase" is identical in hardware as is the Mesmerize, but there isn't a forum for either of them..
I see there's plenty of kernels and etc.. But is there just a simple lag fix that I can do to my Showcase that will make every day use better and less laggy?
A simple yes or no is fine with me.
if there is a way a link post or explanation would be VERY appreciated.
Thanks,
Elijahblake
(PS)Sort of on the same subject, but I read that gingerbread is going to support ext4 file system. I know the Galaxy S uses the RFS file system which I believe is where we get the lag in the first place.. Will it be possible to switch file system formats?
I'm not real familiar with all these Linux formats. Would it be similar to reformatting like from FAT32 to NTFS?

If you can provide some additional information and files, I can port some things such as Voodoo lagfix to your device.
Needed:
stock kernel
stock mbr
mount output
All of the following can be done through adb on a rooted device.
To dump the kernel do:
cat /dev/block/bml7 > /sdcard/zImage
To dump original mbr do:
dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
To get mount output do:
mount
then paste the output of that command as well as upload the showcase.mbr and zImage files here.

look for the thread in the fascinate forum simply titled "root"
also you will need to locate the thread explaining how to get clockworkmod recovery on the showcase in the same forum

will do.. May take me some while to get all this info gathered..
quick question? I've read of some people not being able to see certain apps in the market after rooting.. Is this still the case?
If my phone is rooted and 2.2 finally does come out (officially) will have to un root and remove any lag fix to upgrade? How hard will this be?

To get the upgrade, you shouldn't have to un-root, but you should probably disable voodoo first as the update will almost certainly have a new kernel, and applying the update without disabling voodoo could cause quite a headache.
If you do apply the update right away, you could quite possibly loose root, so you may want to wait until the devs re-root the update. This could make things easier for you as the rooted update will also likely be cleaned up some.
To disable voodoo, you'd just need to create a file called "disable_lagfix" in /sdcard/voodoo and then reboot your phone. See the thread in the dev forum about removing voodoo for more details if you want.

ok well it looks like I'm rooted.. Now I tried to open the ADB that came in the fascinate root zip but it's not opening for more than a split second... you have a download link?
Also can uninstall all this bloatware now??
edit.. thought I had Android SDK on this laptop.. Downloading it now

Alright, so i'm rooted now and got ADB set up.. And this is the first time I've done any of this. So can you please tell me the exact commands to enter. I really don't want to mess anything up.
Thanks,

I have c:\androidsdk
I put ADB inside tools and it sees my device when I run ADB devices
But on the commands you listed nothing happens, I'm not sure if that's the entire commands or if I'm supposed to add something to them..

Try to run the following
Code:
adb shell cat /dev/block/bml7 > /sdcard/zImage
adb shell dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
adb shell mount
or just typing "adb shell" and entering the commands at the new prompt, and typing "exit" to get back to the normal command prompt.

here's what happened..
the first two commands didn't work. DO i need to create a folder name zImages?
The second command said access denied..
You tell me if the mount worked haha..

jt will have to comment on whether that is what he needs from the mount command. Can you try the following to see if it works?
Code:
adb shell
su
shell cat /dev/block/bml7 > /sdcard/zImage
shell dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
exit

well, it granted me SU rights.. but still a no go...

i figured since i was in shell i shouldn't type that.. still got no directory found...

would root explorer make this any easier?

I just tested out all of the commands on my Fascinate and they all worked, so I'm guessing that the Showcase is putting stuff in a different place. jt will have to help you out further as I'm not sure of where else to look for the info he needs.

for the cat command it should bml as in lowercase L, not 1. And it looks like you added a space between the of and = on the dd command.

How do I backup my efs on s4?

I had a google but I could not find anything to help me backup the efs on my s4. I read that because it is Qualcomm it may be different, and also that on the s4 the nv_data files are not in the efs folder.
How do I backup my efs on the s4?

getting my Black S4 delivered tomorrow and was wondering the same After owning many samsung phones I've learned this is the single most important thing to do by flashing everything in sight

just copy EFS folder (root explorer) and put in safe place.
Thats all

dont that break the permissions ect? If not then I'll just drag the whole folder across to my card :victory:

dont just copy and paste efs folder, for permission issue
use dd command in terminal emulator
for I9505 type in terminal emulator:
Code:
su
dd if=/dev/block/mmcblk0p10 of=/mnt/sdcard/efs.img.ext4
dd if=/dev/block/mmcblk0p13 of=/mnt/sdcard/m9kefs1.bin
dd if=/dev/block/mmcblk0p14 of=/mnt/sdcard/m9kefs2.bin
dd if=/dev/block/mmcblk0p15 of=/mnt/sdcard/m9kefs3.bin
then copy the backuped files to your computer

Your choice is also working.
(Permission is not a problem. Paste backup efs folder back/ than flash rom via odin)

NB: nv data files are located in block 13,14 and 15 so it is better also to backup those partitions:
for I9505 ONLY
Code:
su
dd if=/dev/block/mmcblk0p13 of=/mnt/sdcard/m9kefs1.bin
dd if=/dev/block/mmcblk0p14 of=/mnt/sdcard/m9kefs2.bin
dd if=/dev/block/mmcblk0p15 of=/mnt/sdcard/m9kefs3.bin

first you must be rooted
install terminal emulator from play store
open terminal emulator and type "su" (without " "), press enter, then grant permission (it will prompt)
then type dd...... command, press enter. that is it, you will find the backup in your internal storage
move these backups to ext sdcard or computer to prevent wiping

Where am I going wrong? I'm getting permission denied.
Think I've sorted it by changing the permissions of the mmcblk0p10 folder. My efs file is about 13 meg is that about right?

Will do. Is it as simple as dropping them back into the the dev / block folder if something goes wrong?

to restore, put wanted file in internal storage, and type in terminal emulator (example for efs):
Code:
su
dd if=/mnt/sdcard/efs.img.ext4 of=/dev/block/mmcblk0p10
beware restoring to wrong partition may brick your phone! be sure to write it exactly. (for EFS restore to block 10)

I have a very simple question.
dd the tool that is used to back up the efs partition from the terminal comes installed already as part of the stock samsung rom right?
i tried to just run the dd command and it seem to be there on the phone already.
this is stock rom. + cf-autoroot.
i dont have busybox installed.
i was reading a few tutorials which say install busybox............ if DD is already available why install busy box?

Hello buddies! I just want to know if there is a way to backup EFS without root? Thanks

Anyone please???

[Q] Restore 32gb

Lol, what a pathetic answer. I wish it was as easy as that.
By flashing a 16 GB kdz you actually messed with your partitions - that's not so good.
I feel very sorry for you since it's quite a mess you have to go through. Here's the guide.

Thanks, surprisingly it wasnt as bad as i thought, had to change the command lines and add /xbin and worked like a charm.

Only for kdz. Custom roms don't mess with your partitions (unless you're flashing the Korean lollipop)
