Hello, the tablet (Lenovo LePad) was rooted with z4root, but I have run the "unroot" option, and now the tablet is stuck at the boot logo. I have investigated already, but I do not have enough experience to say what is wrong. It appears that file permissions prevent reading some files, e.g. the DalvikVM cannot start up. I have attached the output of mount, dmesg and logcat - maybe an expert can tell me what is wrong? I saw some scripts in /etc which use busybox, but when z4root performs "unroot" it deletes /system/bin/busybox - could this be the problem? I am not sure the scripts are used at startup. I managed to copy the binaries for busybox, su and rageagainstthecage to the device (the only writable place I found was /data/appstore). I can run rageagainstthecage, but busybox and su give the error "cannot execute binary", even after copying them with dd to /system/bin and running chmod 4755 on them. I notice that an already present binary gives the same error message (/sbin/rm). There appears to be a permission problem, but I have not found a way of viewing permissions of files and directories using adb and the shell. I'd be happy if someone with a working LePad could send me their logcat, dmesg and mount output so I can compare to mine in order to understand where things go wrong... I don't know how to proceed at this point. Does anyone have the firmware flash images so I can use fastboot to flash the pad to its original state? The exact description for the pad is: Lenovo LePad Y1011, version LePad-001n. Any help much appreciated!
