try downloading image again
Mount MTP in recovery
Copy image to External_SD
Unmount MTP
Install.

Pretty sure your doing it correctly, but think you may have a corrupted DL. Check the md5 sum on dl page against yours
I honestly do not understand this. It still will not go past the boot logo. The md5 matches perfectly. I checked it.
 
I think something is wrong with your recovery? Why does it say unable to mount?
I suggest redownloading and reflashing recovery
Mine does not say that in red

I'd also say that something is wrong. Try to use the lg flash tool to downgrade to zv3, then flash twrp and the cm12 ROM. It looks like your persist-lg partition is corrupted for some reason, are you sure you didn't format it or erase something on that partition?

Try to go into mounts in twrp and uncheck the box next to persist-lg and try flashing cm12 again. See what happens and let us know.

it will not let me go into download mode for some reason.

Try to download the zv5 modem and flash it. That should restore your laf partition and re enable download mode. If not, then I hope you took a backup of your laf.IMG before you flashed twrp or any Roms, because you can reflash your laf partition from android itself with adb.

Are laf images universal for the volt does anyone know?

I figured out a new development. Omni flashed perfectly with no problems what so ever.
 
I've been running the 2-28 build all weekend, runs great and is for the most part stable. I haven't gotten any random reboots, but some apps force close. Usually only when I'm messing around with settings in the app. Texting and MMS work just fine, calling too, and LTE works faster than my home WiFi connection sometimes! I also seem to be getting better signal overall.

For what its worth, my install process looks like this:
Wipe/factory reset
Flash cm12
Flash gapps
Flash zv5 radio
Flash Universal Boost APN Fix

I don't know if flashing the radio is necessary, and I haven't tried it without flashing the radio, but I've had working data first boot every time with doing it this way.

I haven't tested Bluetooth yet, NFC won't even turn on, and GPS seems to work, but I've yet to give it a road test.
Interesting I followed your install process to the letter but I can't get LTE to work for nothing. Can anyone help me? Also I can't find in settings the option to turn off the mobile data/:
 
I'm still not understanding why my rear camera doesn't want to work for me. Even with Camu it just doesn't work. Everything else works great and I appreciate all the hard work that you have put into this ROM! It's just the rear camera that's not cooperating. Is anyone else experiencing this?
 
As of now I flashed the 2/28 build of this amazing lollipop ROM, and the only things that arent working are vibration and LTE. Does anyone now a fix for either? I flashed using lollipop TWRP.
 
I was having that issue as well, after I flashed the 2/28 version.
But! I think I fixed it by going back into the radio menu and selecting "CDMA auto (PRL)" for the "preferred network ."
You could try that.

Edit: I may have misunderstood. My issue was the signal would repeatedly disappear, then come back, every thirty second or so.
Thank you this worked for me but sadly still no LTE
 
I downloaded a fresh copy of everything but the stuff needed for the downgrade tool. It's honestly just not working. Omni works fine, so I have no clue if it's my phone, or the rom being buggy.

That sucks...

Thank you this worked for me but sadly still no LTE

How long have you been running the ROM? I think for most of us it took a while before LTE would work.. Don't know why but if your apns are right try to just forget about LTE and use your phone as normal...maybe you'll get lucky

I just don't understand it what so ever. This has been the most stubborn ROM I have ever tried to flash. Does CWM work for this? or is there no CWM? Also, should I do it from zv3 or zv5?

I don't think the cwm we have is for cm12.
And I would assume zv5 but I honestly do not know
