Summary
TXOne has identified a firmware upgrade issue that may affect some StellarOne devices that have previously run version 3.1.3137.
As a precaution, the affected StellarOne 3.3 and 5.0 ACF firmware packages will be temporarily removed from MyTXOne until fixed versions are available.
Issue Details
Under certain conditions, StellarOne version 3.1.3137 may leave the bootloader configuration in a partially configured state without showing visible symptoms.
The affected StellarOne device may continue to operate normally and complete later upgrades. However, when upgrading to StellarOne 3.3 or later, the upgrade may fail while attempting to reconfigure the bootloader settings.
If the device is rebooted after this failure, it may enter a degraded state and require remote recovery assistance from the TXOne R&D team.
Affected Customers
This notice applies to customers whose StellarOne device:
- Has previously run version 3.1.3137
- Is currently running version 3.3 or 5.0
