Unbrick Your Device / How to use NVFlash
In the unlikely event you brick your device, don't worry, it can be saved. It's very easy. Please download NVFlash and any ROM flashable using NVFlash above, and follow the steps below.
Put your device in APX mode: Connect your device to your computer via USB and power on the device holding both the Power and Volume Up buttons for about 3-5 seconds. The screen will remain black.
Install the required drivers for APX: If you haven't installed them already, find your “APX” device in Device Manager and update driver manually, pointing it at usbpcdriver in the nvflash.zip.
Prepare your ROM: Download your chosen NVFlash ROM and place the system.img, recovery.img, and boot.img in the nvflashtf directory. "/nvflash/nvflashtf/".
Start the process: Run download.sh (Linux only) or download.bat (Windows only) to start the process.
NOTE: NVFLASH CAN ONLY BE USED ON AN SBK1 DEVICE. PLEASE CHECK YOUR DEVICE IS COMPATIBLE BEFORE ATTEMPTING THIS METHOD.
