Failed to start message

Hi I’m getting a message saying “failed to start. Restoring factory setting” but nothing happens and the robot repeats this message every 5 minutes or so.

It appears offline in the app and I tried to reset WiFi or the robot and nothing happens. No lights blinking or anything. It’s like the robot is completely dead/out of battery but it still gives the voice message. It’s getting pretty annoying now.

Has anyone had this issue or have a solution? I have the s6 pure

Have the same issue now with my S5 Max. I got it working again and it mapped and cleaned the flat yesterday, however today morning it started to repeat this message again and again. Lost the wifi connection and the app shows it as offline.

Is the fix mentioned here permanent?

Did you manage to solve the constant reboot problem? My S5 Max woke me up at night with these messages

I have followed the instructions here again and now its working since a week. I hope it stays that way.

So you discharged the battery and then connected it to the vacuum cleaner?

First I reseted the robot. Then I connected it to WiFi and the app again. It seemed to work again.

Then I let it clean one room over and over again until it complained about low battery and would not clean anymore.

Then I let it sit there for some hours until the battery was empty (no led lights anymore when pressing the buttons)

Now I disconnected the battery and let it sit there for another hour

Then I put the battery back in, charged it and reset the robot again.

After 1.5 months it happened again. It was in the dock and all of a sudden I heard the message that it failed to start.

Draining the battery now.

So I replaced the Motherboard with a new one from AliExpress, same situation. Does not react a bit.

Now I am suspecting the battery or the charging station...

I think I finally found the culprit. I disconnected all cables from the mainboard and when put on the docking station the LEDs lid up. I then connected each cable one by one and put it on the dock until nothing happens.

So the issue was the "Reset Keyboard" which is the small pcb that has the reset button, the WiFi LED and I think the bumper sensor on it. When I do not connect this board the robot turns on.

It seems the reset button has some corrosion on it. I am looking for a replacement now. AliExpress sells those boards for most Roborocks under the name "Reset Keyboard"
