You may have to replace the Infinity v2 10.1 motherboard if the device no longer turns on and works. This process requires a soldering iron, so make sure to follow all the safety warnings and instructions in this guide and in the instructions of your soldering iron. You may be able to replace the motherboard without fully removing the battery from the LCD display, depending on what needs to be fixed on your device. Only remove the battery completely if you need to access the LCD as well.

    • Slightly pry open one corner of the device by using your finger nail to separate the screen from the back case.

    • Use an opening tool to carefully detach the back case from the tablet. Start by inserting the tool where your fingernail opened a gap, and work around all four sides of the device.

    • There will be a slight click noise as you free each tab.

    • Once the case is completely free, carefully lift it and place it face up on the workstation, being cautious not to damage the speaker wires connecting the two halves.

    • Pry beneath each side of the battery using a spudger.

    • The adhesive may be too strong to manually remove, so heat can be applied using the iOpener. This evenly heats the adhesive and allows the battery to be lifted away easier. Do not place the iOpener directly on the battery; always apply heat on the opposite side of the device.

    • You may use a blow-dryer on a cool setting. Keep the dryer moving and at least 6 inches from the battery to prevent dangerous bubbling of the battery due to excess heat.
