Downgrade to C Firmware for ROOT ACCESS
for the D415 LG T-Mobile variant
UPDATED 03/20/2015
First of all, if you've got the D415 stock, you need to know this very important point:
Do not preform the system update when you receive the phone, otherwise you'll have to follow this guide!
But, for those of us on e firmware, we don't have an exploit since even bnr recovery mode is locked down on e firmware. Onward!
STEP 1
Deal with MegaUpload...Ugh. This is the worst part, and takes forever, you'll need the KDZ...

STEP 2
Ge the LG Flash Tool 2014 toolkit

STEP 3
Install B2CAppSetup.exe as administrator.
http://tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
STEP 4
Close it.
STEP 5
Run notepad as administrator. In C:\Windows\System32\drivers\etc there is a file called hosts. Inside notepad open it and add this line:
Save and close. Disconnect and reconnect to the internet.
Reboot.
STEP 6
Run shttps as Administrator.
Run windows enabler.exe as administrator and click the tray icon so you see the word "On".
If you receive an error about your update only working wireless when you try the next step, you must disable WLAN Updates from the programming menu:
WIRELESS FIX
With your phone powered ON:
Dial 3845#*415#.
System programming menu pops up.
Tap WLAN Test.
DISABLE OTA update.
DISABLE any wireless update options.
STEP 7
With phone powered off, Volume Up + Power. This gets you into Download mode. Then connect your USB cable, and run the LG Flash Tool 2014 to execute the flash. It starts the LG Support Tool and preforms the flash. You'll see stuff happening in the shttps server window if you've set it up right.
Do not and I repeat do not disconnect the device while it is flashing. You may hard brick.
STEP 8
You'll be bootlooped, either that or Google Play will crash repeatedly, perhaps some apps will force close, etc. So turn the device off. Just hold the power button until it's off. Hold Volume Down + Power, release Power when you see the LG Logo, then press and hold it again. When you reach the factory reset screen, use the volume keys to navigate the menu and reset by having the proper option selected and pressing the Power button. Phone will factory reset. Now you're out of your bootloop and crashing issue. Factory Reset takes care of some of the leftover garbage from your other ROMs.
STEP 9
Complete! You'll want to ignore the system update prompt and immediately root. towelroot works. towelroot is easy to do...no guide needed. Just enable Unknown Sources, instal it from the stock file manager, ignore Lookout's dribble about it being malware, allow it to install, run it, click make it ra1n, and done!
Thanks to all the devs at XDA for making this possible! If ya fark something up it's your fault! I am not responsible! I'm just a guide!
