I just tried this. Everything seemed to go okay and the installation said complete. It rebooted, but it will not go past the 4G LTE screen. Any ideas? I will try it again to see if it was just fluke.

I just reran it and it is doing the same thing, any ideas?

Update: Awesome, I just pulled battery and did the volume down and power with a factory reset and boom goes the dynamite, just like NEW!
Thanks

Do I need to be rooted or have an unlocked bootloader to do this. Sorry for the stupid question, but I'm about to buy a used Spectrum and I know completely nothing about this device. I own a Droid Bionic and only know things about Motorola devices, not LG. When I get this device, I want to do this to make sure the software is legit. Thank you!

No, this runs from LG's boot loader and it does not matter what state your phone is in as long as you can enter download mode.

Every time I turn off the phone, it stays on the "Verizon 4g LTE" splash screen for quite some time (like 10-15 seconds) before turning off... Is this normal? Sorry for dumb question, just got new spectrum.

It depends on how much stuff it's cleaning up after. If you have a lot of things running in the backround that it has to clean up, then yes, this is normal. When I was on stock, my shutdown was about 5-8 seconds on the splash screen.

Hi again, It's been a while, and I recently saw that CM 10.1.2 is out for the LG Spectrum. I couldn't help myself...I had to give it a try (I'm the guy who just can't get any copy of CM to run on this particular VZW LG Spectrum). No Joy...*sigh*

Any hints, tips, ideas for getting CM to run on my phone? (And as always, if this should be somewhere else, let me know and I'll move it...I realize it's a tad off the original topic)

Can anyone confirm that Neph's update in the OP works for the new zv9? I'm currently on stock w/ root...should I do a zv8 cab flash before taking the new OTA, or can I just do some standard app backups and take the update while still rooted? Thanks in advance for any advice.
