How to Fix Bricked / Unbrick HTC One M8

Any Android smartphone can get bricked and this includes your recently bought HTC One M8 (2014 edition). So, before screaming “what did I do wrong?”, you should understand that soft bricks generally occur right after you attempt applying an unofficial operation and the list includes a variety of procedures such as flashing custom kernel, gaining root access, installing custom ROMs, overclocking the CPU, unlocking the bootloader and more, but don’t forget that you still have a chance to unbrick your HTC One M8.

Anyway, before proceeding, you should know that there are two types of bricked devices: the first soft brick that we have told you about (this is the case that has a chance to be solved), as well as the hardware brick which practically means that you cannot use your HTC One M8 at all. In such case, we must tell you from the start that we cannot give you any tip for your bricked smartphone; you just have to return it to service for technical inspection as soon as possible.

We know that all the operations previously mentioned aren’t official and the warranty of your phone might be voided, but technical assistance is necessary and you have to try. We know that the idea of technical service (which is quite expensive) cannot sound good in any context, so when performing unofficial operations, don’t forget to restore the warranty and save yourself for any unpleasant surprise.

And if we are talking about a software brick, then you can unbrick your 2014 HTC One M8 by yourself, but only after following these steps.

Preparatory steps:

  • Make a full backup of your HTC One M8 and by that we mean saving al the market apps, call logs, contacts list, personal data, text messages, accounts and other info that might be important to you;
  • A computer will be required and don’t forget to temporarily disable the antivirus and any other security protection;
  • You’ll need the original USB cable for establishing the connection between your HTC One M8 and the PC at some point, so prepare it now;
  • Install the phone’s USB drivers on your computer, as well as Android SDK and don’t hesitate to set up ADB;
  • Charge your THC One M8 especially if there is less than 70% power left; it is better to prevent bad things happening than regretting when it is already too late and your device bricked beyond repair.

HTC One M8 and the USB cable
