[T-Mobile LG G3] DudeThatsErin:
I was using this method to root my phone: https://www.google.com/url?sa=t&rct...-VIhhUe3eupYY1bKA&sig2=MyzZOys2QGrlPe6Pwlh_AQ

& I was stupid and combined the 20B file with the 10R file and then also didn't label TWRP as boot.img as the installer tells me to do as I overlooked that.

Now, I can plug in my phone and my computer recognizes it (Windows). I can't view any files though I just hear the sound that something via USB got connected.

I've tried taking out the battery and unplugging it and pressing the power button for 60+ seconds and then putting it back in and trying to go into download mode. It doesn't seem to work. THough I hear the sound of it plugging into the computer.

So, I tried the LG Flash Tool. It fails at model information check. Then has a bunch of zeros after that.

I tried LG Flash Tool 2014 and all of the KDZ files I had on my computer (as I was unrooting just last night and trying to fix stuff and had KDZ files that worked for me to unroot). Well, that fails with all of the files.

Since that didn't work, I've been googling stuff and decided to try the original tool I had and that's when I noticed I didn't rename TWRP to boot.img and I combined 20B with 10R and figured out my problem. So now aboot and laf don't match the software that the phone has installed on it. For this reason, I can't do anything with my phone.

I'm assuming this is a hard brick. How do I fix this? I need my phone TODAY like an hour ago. :/ I was stupid to try and re-root. Ugh.

Can someone help me please?!

EDIT: I tried the LG Mobile Support Tool and I was able to get to the Install USB Driver section. I clicked it and it loads but nothing happens. So, I clicked options > Upgrade Recovery. I entered my IMEI number and it went through the steps and one of my batteries was low so I changed it out and went back through and it stops randomly and tells me to do the Upgrade Recovery which I was already doing. :/

EDIT 2: Tried uninstalling and reinstalling the driver from the device manager and then re-ran LG Flash Tool but it stopped at the model info check fail again. So I tried all of the USB ports on my computer and they all stopped at the same error.

EDIT 3: I can't find my iPhone so I really need this fixed. I just want to be clear that I tried these methods as well and nothing has worked thus far: http://xdaforums.com/showthread.php?t=2785089

I checked the LG website for drivers and such as well so everything should be A'OK from that point of view. I even tried my USB 3.0 that are in the front of my computer.

EDIT 4: Still no luck. Been searching google and other places. I tried fastboot and adb but my phone isn't recognized by those so I can't do those. I want to try and flash the files I found here: http://xdaforums.com/showthread.php?t=2766437

As I know that will help but without fastboot working, I don't see how I can get the files to be seen. Even if I were to put them on my MicroSD card, I don't see how I could flash them onto my phone. :/ That's all I need are the aboot_XXX.img and laf_XXX.img files fixed. UGH

EDIT 5: Called T-Mo to get a replacement. That will be here Monday. Until then I am doing my best to try and figure out how to fix this. I am severely upset by this. Found my iPhone so I won't be without a phone I'll just be upset until UPS gets here on Monday.
