S5 Mini "kminilte" stuck in bootloader

[SirRGB]

Describe the bug
After unlocking the bootloader and the recovery flashing the device is stuck with "Downloading... Do not turn off target!!"
After manually force-rebooting the device to recovery using vol+, power and home buttons it continues to work just fine.

Possibly related to #231

Expected behavior
No user interaction required or describing the process to reboot to recovery.

Log file

*the device was already unlocked, I ticked the box tho iirc

Hard to tell what is going on, since I'm not able to reproduce this issues with the Samsung devices I have available and the logfile does not contain any enlightening information...
Can you interact with the device through heimdall directly when it reaches this stage?

Cant replicate
Maybe Ive tried to unlock an unlocked device?
