[Dell Venue] drewski1969:
So I just got a Dell Venue 8 7840 and have been trying all day to get this to work. I am on Android 5.1 and when I try using the flashing tool I get errors and flash failed.

Anyone know what is wrong here ?

I just got a Venue 7840 and am only on 5.1. Mine says there is no updates when I check. How did you get to 5.1.1 ? Also whenever I try fastboot oem unlock i just get an error message:

<bootloader> checking unlock authorization

<bootloader> unlock command is protected

<bootloader> Go To Android OS to remove the protection.

FAILED <remote: Unlock not permitted>
