Unfortunately, it's not quite as easy. First, we need read/write access to /system, which is only possible if we boot the device with something else than the stock kernel.

to remount /system partition:

if u have adb shell access...

push the busybox binary to /data/local/tmp/

Code: 
adb push busybox /data/local/tmp/.

change permission to execute...

Code: 
adb shell "chmod 755 /data/local/tmp/busybox"

then enter adb shell and type following commands:
Code: 
cd /data/local/tmp/
mount -o remount,rw -t yaffs2 `mount | busybox grep /system | busybox awk '{print $1}'` /system

doesn't work because of no root access "busybox: permission denied"

great so the system MTD block is at /dev/block/mtdblock0

now try this in adb shell:

Code: 
mount -o remount,rw -t yaffs2 /dev/block/mtdblock0 /system
--OR--
Code: 
mount -o remount,rw,relatime -t yaffs2 /dev/block/mtdblock0 /system

and if u dont get any error then post output of:
Code: 
adb shell "mount"

BTW: how come u have "com.keramidas.TitaniumBackup-1"??? is ur device rooted yet? or were u just trying out apps ;) ?

    So here's simple root package that is supposed to work for Arc. It's not tested as I don't have the device myself - just made it for my buddy who got the phone few hours ago and successfully unlocked.

    I modified the original initrd to provide the root shell. Use it to copy su binary file + install Superuser.apk to achieve root.

    This is only for people who understand what they are doing!
    If you don't... just wait for some tutorials etc!

    1. Unlock the bootloader
    2. Download the boot.img http://www.mediafire.com/?il5sb1n45fw5dxa
    3. fastboot flash boot boot.img
    4. adb shell -> remount system rw -> push su into /system/bin
    5. Install Superuser.apk

    Cheers,
    z

    I'm sure it will come but what I didn't understand what it makes harder to root it after the bootloader got unlocked.

    We will keep doing try and fail till we succeed. Thanks for the help

    rooting and bootloader cracking (not needed on Arc) are different things

    rooting involves using an exploit (uptill now psneuter/rageagainstthecage) to gain access to root shell and then install superuser binaries...

    google mostly patches the codes in android for these exploits and so new versions of android are harder to root because newer exploits need to be found...
