### First things on your RDV40
You will need to run these commands to make sure your rdv4 is prepared
```
pm3 --> mem load f default_keys m
pm3 --> mem load f default_pwd t
pm3 --> mem load f default_iclass_keys i
pm3 --> lf t55xx deviceconfig a 29 b 17 c 15 d 47 e 15 p
pm3 --> lf t55xx deviceconfig r 1 a 31 b 20 c 18 d 50 e 15 p
pm3 --> lf t55xx deviceconfig r 2 a 31 b 20 c 18 d 40 e 15 p
pm3 --> lf t55xx deviceconfig r 3 a 29 b 17 c 15 d 31 e 15 f 47 g 63 p

Set all t55xx settings to defaults (will set all 4 at once)
pm3 --> lf t55xx deviceconfig z p
```

### Verify sim module firmware version

To make sure you got the latest sim module firmware.

_Lastest version is v3.11_

```
pm3 --> hw status
```

Find version in the long output,  look for these two lines

```
#db# Smart card module (ISO 7816)
#db#   version.................v2.06
```

This version is obsolete. The following command upgrades your device sim module firmware.
Don't not turn off your device during the execution of this command!!

```
pm3 --> sc upgrade f ../tools/simmodule/SIM011.BIN 
```

You get the following output if the execution was successful:

```
