[Shield Android TV General] adam_ky:
The guide is great but yea it does not go into great detail. Maybe a proper write up will be around at some point. I'm glad its here though, helped me a lot.

I'll try to answer your questions

1.yes

2.latest stable supersu binary should be fine. I think the one u posted is the one I used. I rooted mine Monday and used the latest stable.

3.unlocked bootloader is required for all to the best of my knowledge. If you are going to manually install one I believe.

My shulield updated to 5.0.2 automatically and I unlocked bootloader..twrp.. Then root..

Dev version isn't true root.. Its just elevated permission I do believe.. Regardless you shouldn't have to install any version in order to root.

4. It is possible to install twrp but its unofficial and I am waiting for any kinks to get worked out. I would recommend just fastbooting the recovery.IMG and once booted flash the supersu binary.

5.I cant answer this... I am new to the shield. I have read that if you unlock and root it won't fota. But if it does, all you have to do is flash the supersu binary again and your good to go.

Hope that helps

Hey partner. I see your having some issues and I'm here to help. I think.

I think you have a driver issue and I'll explain why. There is a couple hurdles that stand in the driver installation way.

Windows 10 blocks unsigned drivers I believe and you have to go into recovery and allow them.. Google it.. Its pretty easy.. Its been ages can't remember.

Next.. The drivers. Get them from nvida website. Scroll down and find the adb drivers and unzip..

Here is the issue.. You can right click the INI and install but windows won't actually assign the drivers. The drivers are just installed to a windows system folder. U actually have to manually install all 3 drivers via device manager.

1. With shield at home and device manager open on computer

Turn on adb debuging usb.

2.plug in the USB connecting shield computer. You should see a device pop up in device manager that's not properly installed. Never the less.. Right click.. Update driver manual... List of drivers.. Have disk. Nvida driver folder.. Select android adb from the list.

3. Now for the fastboot driver. U will see it pop up during boot so select it for it disappears and update driver.

So now while everything is connected plug in the controller to other USB port one one closest to HDMI I believe (verify). Now that the remote is plunged in device manager still open go to power and reboot on the shield. Once you see the restarting popup, start holding a and b on the controller.

The shield should boot into fastboot / bootloader. You should see a device pop up in device manager named fastboot.. You want to quickly click on that and update driver same as before, above. This time though select the adb fastboot driver from the list of 3 drivers. There is another driver, composite I believe.. If u see something else pop up at any point install it as well..

Now... If you do all that, you should have the drivers installed properly.

So let the device boot up normal.

Once booted, oncomputer from command prompt:

adb devices

Fastboot boot c:\recovery.IMG

(If that's where you put it.. I would tho simplicity)

Plug in controller and reboot from shield ui while holding a and b

This should boot into twrp.

Now a few things to do in advance...

I forgot to mention above unlock the bootloader.

This has to be done first. Do this before booting to twrp Shield at home. Command prompt open

Adb devices

Fastboot oem unlock

It will say waiting for device.. Reboot the shield with controller plugged in while holding a and b

It should boot to fastboot and run the OEM unlock

DL the super su binary (latest stable) and save it to your download folder (will be fine). That way once your in twrp you can flash supersu.

Once u flash super su do a reboot from twrp. Heads up, it will probably bootloop once then reboot itself and load as normal

Hope that helps. I tossed in the extra but I'm sure the driver part will get u going. Good luck

Forgive sloppyness and whatever else.. Its early and just got off work... And using my phone.
