Symptoms

If you update the BIOS using SupportAssist or Dell Updates (silent install) and the Inspiron or Vostro shuts down. It boots to the BIOS updater and gets stuck at 1 percent. This only happens when updating to BIOS version 1.8.0.

  • Inspiron 7435 2-in-1

This is a side effect from enabling the ROM Armor (AMD feature). Boot mode does not update to the BOOT_ON_FLASH_UPDATE while resuming from S4 when ROM Armor is enabled, the PSP keep blocks access for the SPI ROM then causes the system not to update the BIOS.

The BIOS has been removed from SupportAssist and Dell Update. If you download the BIOS.exe installer from the Dell support website and run the installer, it installs fine.
