Have you tried reflashing stock recovery? Also shouldn't you be in the AT&T One X forum unless of course you have the international version of the One X.
I have tried the stock recovery, but now its in fastboot and won't get recognized by adb on my pc as it did. It just boot loops now at that screen and won't get recognized. And this isn't at. &t

You're suppose to flash stock recovery in fastboot.
I know, I tried when it was getting recognized, now I can't even pick it up with adb
so its telling me to flash the stock RUU, but i cant use adb commands it wont recognize in fastboot, the computer dings when i plug it in, but adb devices comes up with nothing, i tried every usb port on my pc and everything

First of all ADB only works in RECOVERY mode not directly in bootloader. So do the following steps & instal custom rom (Any1 u like).
1. You need recovery.img in your fastboot directory
2. Go into bootloader and connect phone
3. Then use: "fastboot boot recovery.img" (thus booting your image from pc and not the installed recovery).
4. When in recovery, you can use the adb commands.
5. You can try with "adb devices" which should show you serial of phone.
6. command: adb push rom_rom.zip /sdcard

LG G3 Stuck in a Boot Loop. Someone please help me

I think I bricked my G3 :/
I tried usual methods but couldn't get into recovery or download mode, then a few days ago I realized I could get it into this fastboot mode by holding volume up and plugging into USB as you would normally do to get into download mode but you have to hold up for a minute or so (it shows the download mode icon for a few seconds and then goes to fastboot) when in fastboot it connects to the computer and shows in device manager as "android device" and the phone says "processing commands" So I tried to follow this guide http://forum.xda-developers.com/showthread.php?t=2785089 to return it to stock, but I couldn't get it to show up in the LG software.
I read some forum posts about fastboot mode and found that by using the command "fastboot boot twrp.img" (the recovery image I downloaded) in command prompt it would send it to the phone and the phone would display some info and then reboot into TWRP, from here I tried to install a correct rom but the installation starts and there are some errors and then it hangs. I also tried the command "fastboot flash recovery twrp.img" but it fails. This is as far as I have got with it.
It came to me in this condition but the previous owner said he was running Cyanogen and it was working fine until he tried to update it with a nightly build. I suspect he might've tried to install the wrong rom for the phone or the rom was corrupt.
ou could try to revive the phone doing a testpoint and then use boarddiag tools (look in xda thread).
Here is how to make a testpoint: http://forum.xda-developers.com/showpost.php?p=65002893&postcount=17

G4 bricked after trying to instal SU - Help

Hi guys!
I really need your help. Few days ago i had installed Cm 14.1 and everything was fine (i had unlocked the bootloader, installed TWRP, rooted the phone) yesterday night i wanted to install SU so i downloaded the .zip, logged in recovery ..and by choosing "install" i flashed the zip ..but after the restart from twrp the cell didnt work anymore , the little cm alien face is always loading. I tried to to get in bootloader mode by pressing the power button and volume down then relasing it and pressing it again but nothing happens. I got in download mode , connected the phone to the pc (after having installed the drivers) but i always get the message "waiting for device" when i try to get into recovery (bootloader recovery command ..well just because bootloader devices doesnt show me any phone connected) . So actually i dunno how to get in bootloader mode and make windows to see it. Any help would be really appreciated.
i add that i worked on a recovery loaded with fastboot command from windows so i didnt really installed it on the g4 even if i copied the img file on the sd card. Therefore i need to get into bootloader mode in order to send fastboot commands again
Thnx
