WP7702 root password recovery. How?


Hi Guys,
How can I recover root passwd in WP7702? A customer changed it… And he does not remember it. :frowning:

I tried with Developer Studio Legato recovery wizard. After success flashing, I can not enter via SSH, password is required and the blank passwd is not good for it. As I remember blank pw is the default for root.


Hi @tomx,
I think you can reset the password using the swiflash linux tool. You can use the below command which will restore the Linux root filesystem in its original state by erasing the USER1 partition and your password will be reset.

./swiflash -m WP77XX -r

If you have not installed the swiflash , You cna fallow the instructions in the below link to install the swiflash.

Hi muralinagraj,
First problem is I can not login to Legato, because I do not know the password of root.


That is the reason i told to use the swiflash tool to reset the paswword with command i have provided. swiflash is the host tool, you have to connect your board with the Wp7702 module to host PC and execute the command i have provided from the host PC.
