Hi,

I bought a tablet Viewsonic Viewpad 100N for my son. One day, after a month of use, the tablet loop in starting animation.

I tried to start in recovery mode and restore factory settings without success.

I thought, I could flash the tablet with the original stock firmware. Searched in Internet and downloaded stock firmware for my tablet Viewpad 100N (wifi) from following link:

pan.baidu.com/share/link?shareid=435382&uk=2467009660#dir/path=%2F%E5%AE%89%E5%8D%93-%E5%B9%B3%E6%9D%BF-%E5%9B%BA%E4%BB%B6%2FViewPad%20100N%20%20%28PRO%29

This is the Original Firmware published by Viewsonic for Viewpad 100N (wifi)

Once downloaded, i have restored tablet firmware as follows:

- With the tablet unplugged and Power Off, I pressed Vol + and connected the USB cable to the computer

- I installed the drivers for Win7 64 bit

- I opened the soft RK Batch Tool 1.5

- The number one appears in RK Tools with a green square

- CLick "..." to explore and find the .img file

- Click on Restore

The process began and ended successfully

Here is the log:

After restored firmware, tablet restarted with BLACK SCREEN (no image).

I have tried the following:

Upgrade / Restore with RK Batch Tool

Reset + Power on for 30 second

RK Batch Tool 1.7 with Win 8 (64bits Driver) in Win 8 64bit computer

RK Batch Tool 1.6 with Win 7

Tried to press Vol- and Power On with firmware .img in the SD memmory

Always with the same result. Black screen.The tablet works correctly without image. Sound is heard when you press the keys, you can raise and lower the volume can be turned off properly. Always no picture (black screen). The computer recognizes it fine. Works screens backlight.

Someone could help me, please? I have probed everything and I dont know what to do!

Thanks!
