    • Now we are going to separate the back cover. First, warm up the device to soften the adhesive, then use a plastic spudger to open up the rest of the device.

    • Take care when removing the back case as too not damage anything.

    • Remove all Phillips screws and the SIM Tray.

    I've had issues with my SIM tray on this phone and found I need to insert the ejection tool at slight angle to find the trigger point.

    • Use your spudger once again to separate the middle frame. Be careful to take your time here as well so you don't damage anything.

    Tip to separate middle frame: Start at the sim tray area - the plastic clips are weakest there and it's easier to get a plastic tool in.

    • Carefully pry out the old charging board, and put in the new one.

    There is a little glue on the bottom of the old charging board. It may take a little extra pressure to pop it out of place. My new board came with glue installed and a removable plastic strip.

Great guide! I recommend removing the Fingerprint Sensor as a whole. It will make it easier to remove the board, as the charging board has some adhesive, so you will need to pull a bit harder.

When screwing the sensor back, make sure to not tighten each screw all the way at first, but instead alternate between tightening one screw and the other. This will make sure that the sensor is properly aligned! This fixed the issue I was facing with reading some fingerprints after I had my screen replaced by a third party repair shop a couple of months ago. Two birds with one stone!

This guide will help you to replace the charging board - definitely not too difficult. I replaced my board after my A71 stopped charging when I inserted the USB C cable. First it wouldn't fast charge and then wouldn't charge at all.

Thanks man, got it done in roughly half an hour! My phone would charge but not transfer data and this seems to have fixed it.

The guide was very excellent, however after putting the components all in place and booting back into the OS, the finger print reader refused to work anymore (both the original and a replacement one) and as far as i could tell there was no damage to where the reader connects. However, a more important issue is that with the replacement board my phone refused to recognize having the sim card inserted. If there is any software nonsense I have to go through it would be appreciated to have a pointer but at the end I had to fix the USB C port on the original board and reinstall it.
