@AugustRobot_Zou said in How to upgrade the boot loader of coolpi 4b?:
Since I upgraded my PC to Win11, the RKDevTool always cannot find the device of coolpi-4b.
Does the RKDevTool support Win11?
Or could I upgrade the boot loader of coolpi-4b in ubuntu environment?

用这个办法升级成功,避开RKDevTool 在win11驱动问题
