I’ve got the ranger for my son as a Birthday gift, sadly enough after assembling it with the big rubber wheels it didn’t move.
I’ve removed them and tried, it was working, the back wheels was spinning, this didn’t last for a longer time
So it did stop completely and with any command, it just makes the beep sound and nothing else.
After searching many topics, all suggested firmware update, so I’ve connected it to my PC and did the update, which will start and continue to 20% then fails
With the following error
I’ve tried many times, and did restart also, but no luck
Any advice, please?
