HELP-Deleted su file... How can I restore...?

    Hi,

    I've been having problems with my root and superuser. I tried to install supersu also but was crashing every time. The superuser could not get the new su version and generally my acer A100 acted as not rooted. I tried to do the rooting process again and again with no luck. I downloaded the latest su version and tried the commands again.

    Then it crossed my mind to remove the old su from xbin (since I got the new version) and give the commands. So I rm it but then I gave it a closer look and saw that the command did not copy the new su to xbin but was using the cat command. The commands I gave are
    (The su version is supposed to be the latest one)

    $ export PATH=/data/local/bin:$PATH
    $ pwd
    /
    $ cd sdcard
    $ /system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`'
    $ /system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`'
    $ /system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`'
    $ ls /system/xbin/su
    /system/xbin/su
    $ su --version
    0.83:SUPERSU
    $ /system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`'
    $ /system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`'
    $ /system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`'
    $ ls /system/xbin/su
    /system/xbin/su
    $ su --version
    0.83:SUPERSU
    $ rm /system/xbin/su
    rm failed for /system/xbin/su, Permission denied
    $ ls -al /system/xbin/su
    -rwsr-sr-x root root 91980 2012-03-24 01:40 su
    $ /system/bin/cmdclient ec_micswitch '`chmod 6777 /system/xbin/su`'
    $ ls -al /system/xbin/su
    -rwsrwsrwx root root 91980 2012-03-24 01:40 su
    $ rm /system/xbin/su
    rm failed for /system/xbin/su, Permission denied
    $ mv /system/xbin/su /mnt/sdcard/temp
    failed on '/system/xbin/su' - Cross-device link
    $ /system/bin/cmdclient ec_micswitch '`rm /system/xbin/su`'
    $ /system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`'
    $ /system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`'
    $ /system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`'
    $ ls /system/xbin/su
    /system/xbin/su: No such file or directory

    Now I have no su file... how can I restore it? Can anyone send me the su from their A100 (I guess it would be the same)

    I can't understand why the rooting stopped. It use to work ok...maybe the interference of superuser and supersu caused this..
    It happened after a restart...

    Anyhow... how do I get my root back...? Any ideas...?

    I did it... I tried a few different su versions I had downloaded in the past and one worked... with superuser ... the supersu crashes....

    I got rid of supersu and through superuser I updated the su file..it worked like a charm
