Hey, when I try to update my GHL Dosers 2.1 Slave from 1.40 to 1.45, the update cannot process. I do every step correctly in the installation from the tutorial posted in GHL. In the step 5/5 pops up a window that GHL needs to go to bootloader mode, when I press OK the Doser turns off and the update automatically finishes but the version is still 1.40. Any help, tips would be appreciated. Thanks.
