I tried to update the BIOS for my 5055 tablet from version A07 to A08, since Dell shows this as an urgent update. The update appeared to proceed normally, including through restart. The tablet operated semi-normally after the "update", but the BIOS version continued to show A07, and the tablet would automatically re-boot about every 10 - 15 minutes. At that point I was afraid that my tablet had become essentially unusable. I was able to stop the periodic re-booting by downloading and re-installing version A07 of the BIOS. Needless to say, I am not inclined to try updating the BIOS again, no matter how "urgent" the update. After this scary experience, I don't have ANY confidence that Dell can get it right.
I am having the same problem. I have tried multiple times to install the A08 update and the tablet will simply not install it. NO error messages, just won't do it.
I have tried a "normal" download and run. I have also booted from Windows 10 installation USB and tried to run it from there... still nothing.
I'm trying to update it BECAUSE of the random rebooting issue. Reboots every 7-10 minutes for no reason.
Any Dell help here would be appreciated!
It's not clear from your post if you tried reverting to the A07 version of the BIOS as I did. I downloaded and re-installed the "old" version A07 to stop the re-booting behavior that resulted from my attempt to update to version A08. At this point, I am resigned to using the A07 version in order to have a tablet I can use. I'll risk whatever venerability that the A08 version was supposed to address. I don't think Dell is going to devote any resources to fixing this.
