Dell Venue 8 7840

I was looking around about how to root the Venue 8 7840 and followed the instructions step by step but it does not work for this device. When I select the T3 method as recommended, I see the following on the fastboot launcher on my PC.

=======================

DEVICE STATUS: ADP-ONLINE

DEVICE INFORMATION: * daemon

* daemon not running. starting it now on port 5037 *

ADB server didn't ACK

* failed to start daemon *

error: cannot connect to daemon

< waiting for device >

=======================

I'm stuck on what to do. I have rooted other devices so I have a good idea what to do, but I'm guessing because this is still a new device, the method isn't perfected yet, but is there any workaround to this issue?

I'm running Win 8.1 x64 and I have the ADB and Fastboot drivers v1.4.2 installed, and using FBRL 01/17/2015, and SuperSU v2.46 is already copied to my SD card on the device

does anyone knows how to install windows on chuwi v99i? read on internet onda v975i also shipped without windows then they installed windows 8 on it. there were some issues with its hdmi after installing windows due to lack of resistors on motherboard. But chuwi v99i does not have hdmi port so no need to hardmod it i guess. even if someone installs windows 8 on it.

2 Acer Iconias, different results

Hey, I successfully rooted one Iconia with no trouble, however upon attempting to root the second one, the IntelAndroid FBRL 'device status' always says 'UNAUTHORIZED'. Sometimes the 'device information' says ' emulator-5554 device'.

I've done everything the same way on both, but for some reason this second one just will not cooperate. I have made sure that USB debugging is on, and when asked to allow, hit always and yes. I've uninstalled/reinstalled drivers, factory reset, and tried different cables. I'm at a loss at this point, I'm really hoping someone might have an idea of where to go from here.

Any and all help is greatly appreciated!

EDIT: I solved the problem. I had to actually use a different computer to make it work for the second tablet. Don't know why since I had uninstalled everything Android related off my desktop and then tried again with fresh software/driver installs.

OSX and Lollipop

Hi,

It seems this method is designed for Windows based PCs to tether to the Android device. Can this be done with a mac/OSX as easily? I have the dab/fastboot tools, but not sure if the .bat file can be converted easily to a .sh type file.

Also, I recently upgraded my Dell Venue 8 7840 to Lollipop. Do these instructions still apply or would this be a KitKat only process at this point?
