I have tried to upgrade to A04 version (current A01) and the firmare flashing successed but the step "sending intel(r) management engine fw update" stopped to 0%. continue press power button till it switch off, dell forcing bios update,and giving bad bios update making peoples laptop stuck during update,dell need to stop giving bios update every month. The progress is 0% from more than an hour without progress. I couldn't wait for an answer any longer, so I removed the battery et windows has restarted. Dell Inspirion 15-3552 laptop calling for restart to install firmware update although latest update is already installed. Is there any way to fix this? If it won't boot after that, you can try doing a BIOS Recovery.

* Download/Save the latest BIOS file to the Windows desktop* Close/end task all unnecessary software applications (Browsers, Dell SupportAssist, Dell Update Application, Dell Display Manager, Steam, Anti-virus, etc.
