Hi, I recently got my Herelink Beta. I am trying to update the firmware to see if it fixes a few problems. Following the instructions, from a windows desktop, in the CMD prompt, enter adb reboot bootloader. That works, but nothing else. Double click from same folder flash_all.bat and it opens a CMD window and some text, but just sits there. After about 30 sec. the Herelink reboots with no update. HELP…
