I have Vostro 5471 and installed support assist wich informs me about urgent bios update to 1.7.0.
Every time when I try to update - I get error.
I tried to download bios 1.7.0 manually, but could not find on the site dell.com. The latest version wich I have found is 1.5.0 wich I already have on my laptop.
I have the same issue.
But please note that the 1.5.0 BIOS update that I found in Dell's Support>Downloads and drivers (http://www.dell.com/support/home/us/en/04?app=drivers&~ck=mn) (logged in and using my service tag) did seem to update my existing 1.5.0 BIOS.
If I use Support Assist, I'm led to the 1.7.0 BIOS update which fails (error message = FAILED) when I try to download and istall it (within Support Assist).
I did successfully update the BIOs with the 1.5.0 update diredctly from the Dell Support web pages however. The name of the file is <Inspiron5370_Vostro5370_5471_BIOS_v1_5_0_x64.exe>
I would like to know more about the status of the 1.7.0 update.
