hello we bought the robot and started testing, the robot paired and relatively worked properly.

then we tried updating the fireware to the latest version 1.22 and started having problems.

The installation did not run, it ended in an error but it already managed to delete the original fireware that was loaded in the robot.
Now the robot is without fireware and installing new fireware always ends with an error message:/

now because otto ended up without fireware there is nothing to do with him
is there any way to install the fireware other than through the web application?

Thank you very much and any advice

Hi @otahapet welcome to the community!

1. You can still try the online firmware updating by pressing the boot button on the PCB (refer to manual page 3)

2. Another way to update the firmware is by using Thonny.org IDE, Kevin has a very nice video tutorial for that https://youtu.be/fmgQ8Dcg9uM?si=yq7JMqwesUCTRlPm (Select ESP32)
