How do I fully reset a mangOH green to the official firmware image?

I have updated legato to 18.05.1 from 16.10.4 to test the procedure and would like to revert this.

I’ve tried `sudo swiflash -m WP750X -i WPx5xx_Release15_GENERIC_SPK.spk` but after the reboot `legato version` still shows `18.05.1`.

Downgrading with `update legatoz-16.10.4_wp85.cwe 192.168.2.2` does not work since the tool refuses this with

```auto
Systems installed:
  21 [good] <-- current
Legato frameowrk is running.

```

Any help is greatly appreciated.

Frank

try to first

```auto
swiflash -m WP750X -r

```

It will erase the user partition.

To erase legato follow instructions:

legato stop  
rm -rf /mnt/flash/legato/\*  
reboot

Erasing legato as @Francis.duhaut described worked.

Thx.

Yes it’s the best way if you have flashed a legato “update” (stored in RW partition).  
If you have flashed a .cwe, the new legato will be stored into the read only partition.

The only way in this case is to reflash the original firmware or old legato .cwe.

good day.  
Francis.
