Hello dear community, I tried to update the bullet to the latest firmware version today. After I updated Roastime to version 3.3.0, the bullet should get its new stable firmware.
After the start, a red warning sign immediately jumped up at 1%, telling me that my bullet is no longer connected. Then all operating options are frozen. I’ve waited a while, but nothing has happened. The control panel of the Bullet was also no longer able to operate. So after a while of waiting, all I could do was unplug it from the mains.
After I restarted the Bullet there were several (6 I believe) loud beeps, but nothing appeared on the Bullet’s control panel. Everything was off, only the USB people lit up and the fan was on.
There is a constant red light flashing under the bullet where the electronics are located, which I never noticed before.
I then reconnected the Bullet to my Mac (until then I never had any problems with the software) and tried to restart the update. Roastime recognized the bullet and started the update. However, it always stays at 1%, even after over an hour.
the current firmware on my bullet is “unreadeble”.
A walktrough via an “updating manual bootloader” following the video instructions from Aillio was unfortunately unsuccessful. Here, too, the update bar gets stuck at 1%. An attempt with a Windows notebook also failed. Because here I have the problem that the bullet is recognized in the device manager, but no driver is installed. Even if you try to force the driver via RoasTime, it is unsuccessful. I’m slowly desperate. Do you have an idea?
