I'm trying to restore my VZ LG G2 to stock so that it can be returned (audio input is malfunctioning). I am currently running TWRP + CM 11 Nightlies on it.
When I enter download mode, I see the screen "Firmware Update" and it says "B99" and "Rooted" at the bottom.
When I use the R&D Test Tool + LGMobile Support Tool to try to restore to VS98011A_01.kdz, the software update runs on my computer as if it is pushing the update to the phone, but the phone itself shows no actual status change. It just sits there with 0% on the status bar.
When it finishes on my computer it says (on my computer) that the software update was successful. Unfortunately my phone boots into CM just like it normally does with all my apps and data there.
Based on some suggestions I have seen, I have tried manually changing to COM 41 and disabling the device as a modem in device manager -- does not make a difference.
I have no idea why no actual change is happening on the phone. Any suggestions?
