[Dell Venue] Resazurin:
HI all, looking for some help. I recently became the owner of this Dell 7840. It was my sister's former boyfriend's device or something to that effect. It looks somebody did a hard reset and when I boot it up is asks for the google acct verification for acct previously used. This is information that she does not have and is not willing to attempt to get. I tried all the tricks online to bypass to no avail. So I assume its bricked.

Having read through most of the forums on this device, I figured I would several posted suggestions to try and unbrick the device to fix it but have not been able to get anywhere. (Ref How-To: Unbrick Dell Venue 8 7840 by wirebook) I have no way of know if USB debugging or developer settings were enabled but I suppose not.

I can get into Fastboot mode which list the following:

Prod name: BB, Variant - Venue 8 7840, HW version -unknown, Bootloader version - unknown, IFWI version - 0004.FD1F

S/N - 5B700JQA01, Signing - unknown, Secure Boot - unknown, Device State - Locked

The in Green - Fast boot CMD waiting

I installed Drivers, intel flash tool, SDK tools, ADB fastboot - Shows up devices as an Intel Android Device, with ADB interface

It shows up in the Flash tool and I've tried flashing 1-502_droidboot_and_firmware, but it times out everytime at 40 tries.

When I go into recovery mode:

it says Android system recovery, Venue 8 7840-user 5.1 LMY47I BBX803A173600DEL release keys

other than the option to wipe data/factory reset and wipe cache partition - (which I have tried) - the only option is apply update from ADB.

When I run the cwm tether launcher through IntelAndroid-FBRL-07-24-2015 I get:

'Device Status ADB Online', 'Device into 5B700JQA01 sideload'

Try to run T4 - get error 'closed', 'waiting for device' - Which is odd because when I tried it yesterday it said something like this:

All I am trying to do is get thing back up and running - I don't need root or anything else - I would like to be able to sell as a functional device - if not possible no matter, but I thought I would ask the experts here.
