[Q] Phone completely unresponsive

[bikeracer4487]

The phone is off, but holding down buttons gets no response: no vibration, no boot screen, no flashing buttons... This is my brother's phone and I know that he had previously been running CyanogenMod without any issues, but I'm afraid he might have hard bricked the phone. I've recovered from plenty of soft bricks, but I'm unsure of how to proceed with this. Any help would be greatly appreciated.

Try pulling the battery and plug in the USB into the phone and a computer while holding the volume down button and see if it will go in download mode.

Most likely it's bricked. That sucks. But no worries these guys are the best. I have used them. Have your phone back and running in a flash..
