Probably just connections optimizer.

I flashed this rom with cwm and all seems fine. How do I know if I need to update the radio?

Flash the radio if your baseband is c1 should be c8

Try using FasterGPS and see if that straightens it out. It rewrites your gps.conf, worked wonders for me.

As for the actual cause, I don't know.

Have a question.... im a noob to the lgvolt.... thanks bg4m3r..... you helped me so much reading through all these threads i like how you broke it down on another thread. but i have a question. im a noob as i stated before. but are there any cool ass roms for the volt yet? Im coming from a S3 and we all know those roms were sick.... but how do you install CWM on this phone? and... MERRY CHRISTMAS

bg4m3r · Dec 25, 2014

Cyanogen and MIUI are in the works, but neither are fully operational yet.

I'm assuming you are rooted. If so, just download the cwm image and flash it with Flashify.

thebeast567 · Dec 25, 2014

yes. you assumed right. again thanks to your detailed instructions. i just came to my g-ma house. sorry for the delay. but not i tried to do the fastboot but it's not working. i put in the two codes into the terminal and it keeps saying no memory on device. I have a 32gb sdcard with 4gb avail. also the phone was whipped clean so im not sure but now my phone wont go into download mode because fastboot trys to work but it dont... it keeps saying processing commands for about 5 mins then it says
[320040]--reset--
[320040]EP1/out FAIL nfo=40 pg0=ffdb840
[320040]--portchange--
[320050]usb_read() transaction failed
[320050]fastboot: oops!
[320180]fastboot: processing commands

then the number switches and keeps saying the same thing still connected to pc running windows 8.1

whats flashify and how to put it on the phone

bg4m3r · Dec 25, 2014

There's no need to mess with fastboot if you're already rooted, or at least on v3. Flashify is an app in the store.

Why didn't you try a different combo?
Vol- + power
The instructions are all laid out for you
http://lmgtfy.com/?q=lg+recovery+combo
Please stop complaining. If it's not booting then you probably flashed the wrong cwm.

bg4m3r · Dec 25, 2014

Vol - + power to boot recovery. You can't flash a full ROM with Flashify AFAIK. Updating to v4 should restore download mode. I don't know if the OTA update would overwrite cwm. I wouldn't risk it.

With cwm recovery, you shouldn't really need download mode, but if it's not restored with v4 and it's really bugging you, you can restore the backup of laf you should've made, or if someone can post a copy.

bg4m3r · Dec 25, 2014

The error you are getting from fastboot is due to the phone not being connected to a computer and/or not receiving commands.

thebeast567 · Dec 25, 2014

Ok... after hours of using my brain power i figured it out.... why ya'll aint tell me Fastboot was computer to phone lol i said i was a noob.... lol but damn this lg shit is crazy. i loved how simple galaxies was but hey can't be happy feeling accomplished

Please be careful. It's pretty clear that you are a novice with this stuff. It is overly easy to mess up your phone. Check, double check, triple check if you have to. No one wants you to brick your phone!

I'm fairly certain it's explained in the instructions that fastboot involves sending commands from your computer. I'm guessing the Galaxy is the only phone you have experience with? You can't expect everything is going to be the same on all devices. Please read thoroughly before rushing ahead.

thebeast567 · Dec 25, 2014

man, I finally got it to do what i wanted so far. but whats up with the radio thing

When updating the kernel, there is no visible difference in the "Software Information" menu on the phone. With both ZV3 and ZV4 it reports "Kernel version 3.4.0+". Just to confirm that the kernel did get changed, here is some more info generated via "adb shell cat /proc/version". You can see that the ZV4 kernel has a newer date.

ZV3:
Linux version 3.4.0+ (lgmobile@LGEACI1R3) (gcc version 4.7 (GCC) ) #1 SMP PREEMPT Thu Mar 6 12:48:55 KST 2014

ZV4:
Linux version 3.4.0+ (lgmobile@LGEACI2R14) (gcc version 4.7 (GCC) ) #1 SMP PREEMPT Mon Aug 18 17:45:38 KST 2014

You can also just run this command in terminal emulator.
