+####Troubleshooting
+I can't overwrite my flash and get the error "Lock Error Bit Detected":
+```
+> flash erase_sector 0 0 15
+status register: 0x1048b205
+Lock Error Bit Detected, Operation Abort
+failed erasing sectors 0 to 15
+```
+
+In this case you need to clear the protection on that bank (or banks).  This can be done as follows:
+
+```
+flash protect 0 0 15 off
+flash protect 1 0 15 off
+```
+
+When successful, you should see a message as follows:
+```
+> flash protect 0 0 15 off
+cleared protection for sectors 0 through 15 on flash bank 0
+```
