Unbricking Allwinner Tablet and Phone
Unbricking Allwinner Tablet and Phone

It’s regrettable when your device is fried. Sometimes a device may break due to a bad software update or other hardware issues. Mostly it occurs due to our experiment on new software, firmware, and other tools. There is very little chance of devices bricking naturally. I have soft-bricked my mobile and tablet many times. But bricking my Allwinner Tablet LUV Pad AD701 was the worst. It took a lot of time to fix the device. I learned a lot because the process is pretty unique. Therefore, this guide is to help everyone who is in the path of unbricking Allwinner tablet or mobiles.

At first, it is a Japanese tablet that I bought from Japan. Second, there were no dealers in my country. After researching for a few weeks, I found the solution. The solution process is quite simple but tricky. It needs a special procedure to connect the device and install the firmware. After a bit of search, I found the manufacturer’s original website for the software and guide. This unbricking process can be used for many Chinese and Japanese tablets or mobiles. The flashing process is easy, but the problem is finding images, installing drivers, and connecting the device. I felt that many people might need this. So I made this tutorial to help all of you.

There are two types of Bricking, and they are Soft Brick and Hard Brick. Hard brick is complex and can require a resistor combination called “Zig” to fix. I am dealing with soft brick that can be solved by installing the correct firmware. I actually bricked my firmware while trying the CWM Recovery tool. After that, the device didn’t boot. My tablet was stuck on boot loop in CWM recovery. I took it to many repairing shops in my city, but none could solve it. My tablet was just stuck on the screen shown below.
