Dell Inspiron 3847 BIOS Downgrader

Officially, Dell Inspiron 3847 BIOS firmware updates are not possible to rollback once applied. That is to say, once a Dell is running on a higher version firmware, it can go to a newer firmware version, but it is not possible to downgrade to a previous version.

For example: A Dell Inspiron 3847 with the latest A11 firmware cannot return to the A01 firmware, even if it originally shipped with A01.

Fortunately, there is a way to bypass this behavior. Simply download the tool below, run it, and the Inspiron will revert to version A01. From there, the official Dell tool will allow installation of any desired firmware.
