Root Tried to root, bricked, help!

[ProxDroid]

I have a request from a customer to write an app that requires privileges that are only available on rooted devices. To build it, I need a rooted device.

I followed some instructions I found to root the device, installing "UPDATE-SuperSU-v1.75.zip" and "openrecovery-twrp-2.6.3.1-deb.img".

I suspect this was a mistake. Now, the device never boots, and I can't seem to restore it. When I try to install the factory image from Google I get:

razorg-jls36i] ./flash-all.sh

I should mention I am on a Mac, and I have the dev tools installed.

Any help is greatly appreciated.

Hello and welcome to the forums. I see your android device has a rooting problem . Need some information to help you repair this problem . What is the device doing now . Did you have a fully charge battery and can you still access fastboot recovery .

Hi, and thanks for the help.

Right now I can get it to fast boot, but when I choose to boot normally it gets to the "Google" logo and never proceeds past that.

It's fully charged and plugged into the USB port on my Macbook Pro.

Use this flash the one for your device in the fastboot

It looks like you tried to use the recovery designed for the LTE version of the Nexus 7 when in fact you only have the Wifi Version. Downloading this image in particular and running the flash all script should fix you right up.

Thanks for the help. With the advice above I was able to un-brick the device. Now, to try again to get it rooted, so I can meet my client's need for a system app

What system app are you looking for

What system app are you looking for

I wasn't looking for one, I was writing one. I just finished it, in fact, and it works great on Android 4.3. Doesn't work on 4.4, but the client is ok with 4.3 for now. Apparently Google changed the requirements for WRITE_SECURE_SETTINGS between 4.3 and 4.4. The client will be very happy though.
