Updating my 9470’s firmware to 4.7.0 yesterday via Jabra Direct failed. The 9470 screen was white and the 9470 was not listed in Device Manager under “Sound, video and game controllers.”
The Jabra support document How to recover a Jabra PRO or GO touch screen after a failed firmware update.pdf instructs to download the firmware file, which is correct, but the manual update no longer works through Jabra PC Suite. Jabra support gave me the correct steps:
1. Download the firmware. Do not unzip it.
2. Exit from Jabra Direct.
3. Run the separate program “Jabra Direct Firmware Updater”.
Update September 15, 2020 Recent comments (below) report that this updater is part of Jabra Direct 3 and has been removed from Jabra Direct 4.
4. Apply the firmware to the device.
This un-bricked my 9470.
