# AT+RESTORE=, using an undocumented value for

## Question

Asked by AndreyS on 2023-03-30 in Wireless.

By mistake, the “AT+RESTORE=2” command was sent instead of the “AT+RESTORE=1” command.

```
AT+RESTORE=2

OK
76687460787878787878787878787878787878787878787878787878
76687460787878787878787878787878787878787878787878787878
76687460787878787878787878787878787878787878787878787878
```

1. What happens after executing the “AT+RESTORE=2” command?

2. What happens after executing the command “AT+RESTORE=type” if “type” contains an undocumented value?

```
AT+RESTORE=3

OK
value = 3(0x03)

ready
```

1. Could this have led to the commands “AT+CWJAP_DEF…” and “AT+CWJAP_CUR…” now they always return the answer “ERROR”?

Hello [@AndreyS](https://maker.wiznet.io/u/andreys)

When recovery is not possible due to incorrect settings, try using it after re-writing the F/W.

Please refer to the document below for how to write F/W.

[@austin](https://maker.wiznet.io/u/austin) thank you for the answer

I rewrote F/W before and after writing this post, but it didn’t solve the problem.
