Volume up plus camera?
Are you sure your buttons are working (no hardware defect)?
Check if files (/sdcard/update.zip and /sdcard/OpenRecovery) are there and fine. You can try to copy fresh ones just in case.
Or try /system/etc/init.d/60autoboot_or and set execute permissions (755 will do).
Perhaps sdcard is corrupt?
