Fixes & Enhancements
- Fixed the issue where TPM could not be initialized message is displayed after updating the Trusted Platform Module (TPM) firmware.
- Fixed the issue where the Dell logo that is displayed when you update the BIOS is bigger. This issue occurs when you connect a 4K monitor.
Important Information
- Once the BIOS is upgraded, you cannot downgrade the BIOS EXE/Recovery (RCV) to versions earlier than 1.6.0 due to restrictions. BIOS downgrades are restricted when there are security updates and important fixes with earlier versions that impact the functionality of the system.
- If you want to downgrade to an older BIOS version, you may follow one of the below steps:
1. Use BIOS Flash Update in the F12 Boot menu to downgrade the BIOS.
2. Disable the SMM Security Mitigation option from BIOS setup menu before to attempt the downgrade in Windows operating system.
- BIOS updates take no more than 5 minutes to be installed on your system. You can install the updates in the background while using the system.
