Temporary fix for the FastBoot loop problem: Search the HTC One X forums for "SOLVED: Stuck in fastboot with low battery. Use this BATCH file! by floepie" - all credit to floepie

The script continually reboots your phone, which allows it to slowly charge (plug it directly into the motherboard, good USB cable, and non-essential USB peripherals unplugged for max amperage). Eventually it will boot normally, though in my experience, it's taken hours. Not sure if it's actually the battery charging or just random luck with the number of reboots. 80% battery and 4.1-4.2V might be the magic numbers. This probably won't work if you had a bad flash or other preexisting condition.
This ridiculous problem now happens to me every time my phone dies or I have to reboot it. I have the recommended TWRP, s-off, unlocked, no tampered message, etc but pressing recovery just reboots it into fastboot again. I'll probably try re-flashing stuff or just use this method until it's completely dead. Bought it in 2014 when it was >$200 unlocked but I excessively baby my devices; 3 years is good in cell phone years, but I was expecting more.
I really like this phone, but it's getting hard to love between this, the pink camera issues, and speakerphone problem with the older InsertCoin (my preference). Good size, snappy Sense interface, and decent battery life when used with a nice, slim kernel and rom.

Windows - Put the following into a .bat file in your adb directory:

Code:

@echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start

Linux/Mac - Put the following into a .sh file in your adb directory (untested):

Code:

#!/bin/sh
while true
do
./fastboot getvar battery-voltage
./fastboot reboot-bootloader
sleep 5

Edit: Latest numbers are 2 hours of rebooting to get to 4110mV / 82% reported battery (started sub 4V after a phone freeze/reboot)
