What if htc one m8 can't boot?

1. This situation may be because the machine has been brushed and the system is not very stable. At this point, you can plug in the mobile phone charger. The charging indicator light may not be on, but please make sure that your power supply is connected properly. Then press and hold the "Power" and "Volume+"keys at the same time until the phone vibrates for more than 3 times. Press and hold the power button again and turn it on to see if it can return to normal.

2. The mobile phone can't be opened. Generally speaking, the most common method is to take out the battery, then put it back and turn it on again. Of course, this method is limited to non-integrated mobile phones. If this method doesn't work, you can try the first method.

3. Connect the data cable first and try to charge the computer for 30 minutes. Sometimes the reason why the computer can't be turned on may be that the battery is dead, and it enters a dormant state, and it can be restored as long as it is reactivated.

4. If it can be confirmed that the mobile phone has power, it still cannot be turned on, which is probably caused by poor contact between the battery of the mobile phone and the mobile phone. In this case, you can take out the battery, then wipe the metal part of the battery with a dust-free cloth, reinstall the battery and restart the phone. This method is suitable for this kind of mobile phone without integrated battery.

5. The mobile phone charger has been used for a long time, and the data line of the mobile phone may be broken due to repeated bending, especially the wire at the socket, which is often bent and easily broken. Try a different charger, and it is best to match it, because different models of chargers may not support your mobile phone. If there is nothing wrong with the data cable, you can try to replace the battery.

6. If the phone still can't be turned on after trying all the above methods, then you can consider repairing it. If you want to send it to the store for repair, remember to find some regular mobile phone repair shops, and don't go to some brand-name stores for cheap.
