Rut240 uboot file

Hello to everyone, yesterday I tried to update a clients rut240 that was on 00.01.07 if I am not mistaken and the device bricked!
Right now it boots up, gives me access to the login page, after the login it is asking me to change the default pw as it should but nothing happens next, when I click apply the login page shows up and I can login again with the default pw and again it asks for a pw change!
The 192.168.1.1/index.html is not available but I can access the 192.168.1.1/uboot.html so, where I can download uboot files to try to unbrick the device?

Good afternoon,

In your instance, if you are able to reach the Uboot page, you can upload the regular firmware of the device, and see if you are able to get it working.

However the full uboot procedure can only be performed in our Warranty facilities, therefore if the device is still within warranty, please contact your distributor for further assistance.

Regards,
Arturas
