Problem seems in your system toolbox symlinks hijacked by a bad busybox installer

All these entries should have been kept linked to toolbox instead of busybox. But, probbaly some third party busybox installer (market installers, a ROM you installed...) linked them to busybox without resetting toolbox links

So, as they are linked to busybox, they got deleted and you end up with a corrupted toolbox installation

Try this below script:

#!/system/bin/sh
toolbox ln -s /system/bin/toolbox /system/bin/cat
toolbox ln -s /system/bin/toolbox /system/bin/chmod
toolbox ln -s /system/bin/toolbox /system/bin/chown
toolbox ln -s /system/bin/toolbox /system/bin/date
toolbox ln -s /system/bin/toolbox /system/bin/dd
toolbox ln -s /system/bin/toolbox /system/bin/df
toolbox ln -s /system/bin/toolbox /system/bin/dmesg
toolbox ln -s /system/bin/toolbox /system/bin/hd
toolbox ln -s /system/bin/toolbox /system/bin/id
toolbox ln -s /system/bin/toolbox /system/bin/ifconfig
toolbox ln -s /system/bin/toolbox /system/bin/insmod
toolbox ln -s /system/bin/toolbox /system/bin/ionice
toolbox ln -s /system/bin/toolbox /system/bin/kill
toolbox ln -s /system/bin/toolbox /system/bin/ln
toolbox ln -s /system/bin/toolbox /system/bin/ls
toolbox ln -s /system/bin/toolbox /system/bin/lsmod
toolbox ln -s /system/bin/toolbox /system/bin/mkdir
toolbox ln -s /system/bin/toolbox /system/bin/mount
toolbox ln -s /system/bin/toolbox /system/bin/mv
toolbox ln -s /system/bin/toolbox /system/bin/netstat
toolbox ln -s /system/bin/toolbox /system/bin/printenv
toolbox ln -s /system/bin/toolbox /system/bin/ps
toolbox ln -s /system/bin/toolbox /system/bin/renice
toolbox ln -s /system/bin/toolbox /system/bin/rm
toolbox ln -s /system/bin/toolbox /system/bin/rmdir
toolbox ln -s /system/bin/toolbox /system/bin/rmmod
toolbox ln -s /system/bin/toolbox /system/bin/route
toolbox ln -s /system/bin/toolbox /system/bin/sleep
toolbox ln -s /system/bin/toolbox /system/bin/sync
toolbox ln -s /system/bin/toolbox /system/bin/top
toolbox ln -s /system/bin/toolbox /system/bin/touch
toolbox ln -s /system/bin/toolbox /system/bin/umount
toolbox ln -s /system/bin/toolbox /system/bin/uptime

Copy paste it in a sh file using notepad++ with EOL Conversion set to unix format and run it in a su terminal

If complicated for you, use attached file:

- download toolbox_fix.txt

- rename it to toolbox_fix.sh (do not open it or edit it in windows notepad or it will be corrupted)

- put it in /system/bin in your phone using a program like root explorer (you have to mount /system as rw in root explorer)

- in root explorer, long press the file name and select to change permissions, check all boxes there

- save settings

- open terminal and type:

su
sh /system/bin/toolbox_fix.sh

Now, reboot and all should be fine

If not, in terminal type:

su
ls -l /system/bin >/sdcard/ls_log.txt

And attach here the ls_log file you will find in root of your sdcard

Please report back if this fixed your issue. If it is the case (which I am quiet sure), I will edit my uninstaller script to automatically make these symlinks for people in situations like you
