So, since getting the G3, I've been using my G2 as my guinea pig. I used to have a couple Galaxy Nexus devices kicking around where I'd root/flash ROM them all the time. So it was a little different with my G2...
Regardless, I am finished playing with ROMs, especially if it were my daily driver. I had tried several ROMs, CloudyG3, AICP, etc... each were nice and had their quirks, but I'm really anxious to see what LG has in store for when they throw Lollipop OTA.
In order for that I had to figure out how to flash back a stock ROM for the phone. Give me TWRP and a .zip and I'm great. But sometimes OEMs have their own flashing tool, like Odin for Samsung. LG has "LG Flash Tool". And these things usually give me the heebie-jeebies as you often don't have many options, so I'm always afraid of bricking.
So I followed the thread over at XDA and it was fairly straight forward:

So I followed the thread over at XDA and it was fairly straight forward:
- Download your LG driver files (if it's not being recognized)
- Download your appropriate original firmward file (KDZ file)
- Download the LG Flash Tool (2014)
All the downloads done? Great, extract the LG Flash Tool somewhere on your drive, and to make it even easier move the KDZ file into that folder too.
Now, let's flash
- Put the phone into 'download mode'
- Make sure the phone is off
- with the phone off, hold the VOLUME UP button and plug in the USB cable
- eventually the screen will say 'download mode'
- Run the LG Flash Tool
- it's weird, I know, but leave the Type as CDMA
- leave the PhoneMode as DIAG
- Select your KDZ file by hitting the little yellow folder button
- Select which style of flash you want to do
- NORMAL FLASH means you'll just be flashing over something (okay if you're probably flashing stock ROM over stock ROM) - it leaves your files intact
- CSE FLASH wipes everything (probably best option)
- Next screen that comes up, just click Start
- It'll now ask you to choose a country and language
- I know it's weird, but leave it as is (changing it to Canada/English caused problems for me). Leaving it as it is will let you go on.
- Now another window will come up and it'll start doing some stuff. All's good until (at least for me) a screen pops up saying it's lost connection. Don't lose hope - and don't press 'okay' to cancel the upgrade.
- You'll notice on the phone files are transferring and everything's fine.
And that's it, let it's do it's thing and eventually the phone will reboot back into the normal original screen. Again, check out the XDA thread for any questions you might have.
One word of caution - for some reason, when I flashed the Bell KDZ file on my device whenever it would reboot it would forget the WiFi passwords. Doing a Google search it sounded like it's a common thing for the Bell device. Now... this was originally a Rogers phone, but I've unlocked it for Bell, so that might have something to do with it (but others were having the issue out of the box for a Bell phone). So, I just flashed the Rogers KDZ and if I needed to; put in the APN for Bell. Everything's working swimmingly now for me.
Now just to wait for the LG G2 Lollipop OTA!
