Known Issue:

• Upgrading directly to the January 2026 firmware, which includes BIOS 2.25.0, may fail on systems running BIOS versions prior to 2.12.2, due to compatibility constraints.

Required Action:

omreport system version

• If the BIOS version is earlier than 2.12.2 contact Dell Customer Support to apply the September 2021 firmware block (AVP: Gen5aSep2021Blk338753.avp) before installing the January 2026 firmware.
