Default [Solved] libbinder.so

I have a problem with getting it to work with my X8 1.6...
I have installed JDK, Android SDK, X8 drivers, everything is recognized fine. I have rebooted PC and phone, unmounted SD card, set to debugging mode, clicked root and OK - everything seems to be working fine... however when it tries to test su, it fails. I can connect to phone via command prompt (adb), and it even has root access (displays # instead of $ at beginning of line)... Superuser icon is displayed in menu. Judging by the log in SOC 1.5.5, everything seems to be fine too - pushing files, remounting /system etc... But it fails on running su - in adb it says:
"Library 'libbinder.so' not found"
What could be the problem? I have already tried everything about enabling and disabling developer mode...
Oh, and, almost forgot - now it seems to have root access and when I click Root button again, it flies through the process, again everything seems to be fine, but it fails again on running su - same error again - libbinder.so is missing.

Edit: Sorry for bothering... a little time spent on Google and it seems that su file wasn't for my device - replaced it and it's working now!
