Help! i have the t-mobile variant, D80120e. did the 4.4.2 update, then rooted with towelroot, now i dont have the Download mode, i am trying to restore to the Stock firmware (Unroot) but its not letting me go to the download mode. i tried installing the TWRP recovery, but just soft bricked my phone, so when i try to restore through the device, it boots up to the lg screen and pops up an error on the top left of the screen. when i try to go in to download mode, (by holding the volume up, and plugging in the device) just boots up with the LG Logo and shows the battery charging, and my pc recognizes it. is their any way i can restore to stock firmware or unroot the device to its factory state?
