It’s really sad when your device is fried. Sometime a device may break due to a bad software update or other hardware issues. Mostly it occurs due to our experiment on new firmware and other tools. There is less chance for bricking of device naturally. I myself 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 and it is pretty unique. 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 brought from Japan. Second, there were no dealers in my country. After researching for a few weeks, I found the solution and this is the tutorial to help all of you. There are two types of Bricking i.e. Soft Brick and Hard Brick. Hard brick that requires a resistor combination called Zig to fix. I am dealing with soft brick that can be solved by installing correct firmware.
I bricked my firmware by 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 almost all repairing shop in my city but none could solve it. My tablet was just stuck in this screen shown in the picture. After a bit of search, I found the manufacturers original website. This unbricking process can be used for many Chinese and Japanese tablets or mobiles.
