Did you happen to try installing the P7510XABKMP_P7510UEKMP_HOME.tar.md5 that came in the sgt10.1_root_unroot.zip? I know it is for a different device but give it a try and see if the problem is still there!
Then reflash the P7500XWLB1_P7500OXXLB1_P7500XXKL4_HOME.tar.md5 I accually had to do this on a different device "HTC Desire HD"! Different problem the Phone was bricked nothing would show up on the screen so i flashed a Sensation stock Rom still didn't work but when I flashed back my stock Rom everything worked perfect!
