Hi, Is it possible to downgrade the firmware on anABV378PRO? I have upgrade a couple of boards to the latest firmware (8.12 Build 4) to take advantage of using HID drivers but this has caused an issue with the boards. Now when you try to calibrate the pens, the board thinks the pen is in a completely different position then it actually is. Eg, you could move the pen up and down near the bottom of the board but the board will detect it is moving left to right at the top of the board.

Initially pen stopped working in Windows 10 1809 and needs to restart the PC to fix for a while, then I upgraded the firmware to V8.65 Build 1 in order to fix this issue.
Now pen does not work at all in our Active Board, is there way to downgrade the firmware or any fix?.

Thank you for your post.
It appears by the firmware version listed that you are having this issue on an AB500 board. Could you please provide the model/product code to verify?
What firmware version was the board showing prior to the upgrade?
If you have not do so already, please restart the computer after the update and reset the board per the following article: https://support.prometheanworld.com/article/1287/
We look forward to your response.
