Bluetooth stopped working after patching DSDT to show battery status and now shows "Bluetooth not available" with the Bluetooth logo crossed.

My laptop is a Lenovo ThinkPad Edge E531, model number 6885-EUG. In my last post, I asked about patching the DSDT to show a battery status. After patching the DSDT and rebooting, the Bluetooth just stopped working. What can I do now? Thanks in advance
