Put the latest one on an empty (non-bootable) 2-GB USB that's formatted FAT32. With BIOS Downgrading enabled in BIOS setup, plug that USB into PC with power fully off. Power on and start tapping F12. When the F12 menu opens, select the BIOS flash update option and follow the prompts.
About 4 days ago my Inspiron 3910 was offered a number of updates through the DELL update system including one for the BIOS. Having accepted it, instead of starting straight up into w11 after the install, it opened with a screen requiring one of 2 options to be checked. both had Inspiron 3910 in the wording with one including the phrase China HDD protection. There was no guidance as to these choices at all. I had no idea which to choose or their significance. Because I thought I remembered reading something about protection relating to the 3910, I selected that option. It went to another screen but in the panic of the moment I don't recall what happened there! Anyway my PC is now identified as "Inspiron 3910 - China HDD Protection" which I'm pretty sure it wasn't before and I realised I must've selected the wrong option. I've tried downloading an earlier BIOS to reverse the update but when I attempt to install it it fails to install with an error showing "unsupported image". As far as I can tell the PC is running fine. But I would really appreciate advice about this situation and any implications. Thanks
