EDIT: This issue should now be fixed in the latest version 1.14.2 but I'm leaving these instructions here for now in case the issue is still not 100% resolved. If you are prompted for a Pybytes token even though you selected "stable" as the firmware type: Please post your OS type (Mac, Windows (32/64bit), Linux) and exact version here. Then please use the following firmware updater: MacOS Windows Linux Please ignore the message about an upgrade being available.

@dhruv I have changed your device from 868MHz to 915MHz. Please re-run the firmware update tool to flash the new region.

@jmarcelino Thank you. That's what I needed to know :)
