Hi,

After many attempts to make update from USB, I finally decide to ask the community.

I have a R820 that I want to update. The Http way (downloads.dell.com) is not working as I need (So slow and usually ends with errors).

The DRM option fives this alert "Some plugins are not available for export" when I try to make a bootable USB.

So I decide to make updates trough Lifecycle Controller from USB. But things are not going well as I hope: Many times it ends by "generic" errors. So I have some questions to figure out what I'm missing:

- USB should have a specific or limited seize to work?*

- I formatted it in FAT32. That's right?

- I downloaded ALL drivers from Dell website MANUALLY. But There is different formats of files (EXE, SIGN, BIN, ....) witch format I should use to update?

- How can I make updates: Can I put all drivers in USB and launch the LC update? In separated folders? In on folder? 

One last question: Why it is so complicated to make a simple update ????!!!

Thank you in advance
