When upgrading the basic BIOS, the Toolkit tool was able to activate the basic BIOS version successfully, but the update of the basic BIOS version was unsuccessful, suggesting that "the software version has not been updated", and the site was checked through the command line, and the software version was still the original upgraded version, which had indeed not been updated;

Huawei OSN3500 Device Alarm Messages

The base BIOS update was unsuccessful, and the device had no abnormal alarms; the Toolkit tool prompted "Software version not updated";

Processing

1、Check the upgrade steps, consistent with the instructions in the upgrade guide, to rule out operational problems;

2、Suspect Toolkit tool problems, the scene using navigator software for basic BIOS upgrade loading, still can not operate successfully;

3, upgrade the software package problem, the scene by re-applying for new software to reload, the basic BIOS software still can not be updated;

4、After the company finally analyzed and positioned, the scene from the main master OFS2 copy of the basic BIOS to the main master OFS1 file system, that is:

:sftm-copy-file:bid,"/ofs2/hwx/basebios.hwx",bid,"/ofs1/hwx/basebios.hwx";

5. # Activate the base BIOS, bid is the main control board bit

:cfg-active-basebios:bid

6, and then finally use the tool to activate (i.e.: reset) or manual soft reset the motherboard. However, after this operation, the basebios.hwx file will be left in the motherboard, if the motherboard space is insufficient, you can manually delete the file after the activation is completed.
