I recently purchased a HTC 8X on eBay. The device was stuck in a boot loop so I got it cheap. I did some research on how to correct it but, nothing worked. No method of hard reset or combination of button presses could fix it. I determined, after reading many posts about how the phone died while watching a video or updating software, the power was too low for the phone to charge while constantly trying to boot. The boot process was sucking what little juice the charger was providing faster than the charger could provide it.
Disclaimer: This will most definitely VOID any warranty you may have. There is also a good possibility of physical damage without great care.
Now for the hard part (unless you have tinkered with these things before). The only way to charge it without it trying to boot is to disconnect the battery. Yes, this does require disassembling the phone. However, you only have to remove the case.
The trick is to heat the outside edges to soften the adhesive and use a guitar pick or similar tool. There are several instructional videos on the usual sites.
Once that is removed you can access the battery terminals.
Remove the 2 small phillips head screws from the flat, silver contact near the bottom edge and gently pry the contact free of its mount. (Pry is a strong word as it takes very little effort to remove the contact.)
Now, you'll have to destroy and old charger. Clip the end off of a charger and expose the red and black wires.
Connect those wires to the battery terminal. It is marked + and - on the underside of the ribbon going to the contact. As you're looking at it from the bottom of the phone with the back facing up, the + is on the left. Obviously red wire to + and black wire to -.
Plug in the charger and let it sit for 10 to 15 minutes to get a decent charge.
Reassemble the device and hold the power button until it turns on (no reason to do a hard reset here). Watch in glorious amazement as your HTC 8X comes back to life with all data and settings intact. Hooray!!!
I have since purchased a 2nd HTC 8X that would not power on and tried the same method. I now have 2 fully functional 8X's.
