Sorry for posting here but disscusion about this are all over international and sprint optimus g and is also not for developement section.
LS970 has the same hardware as E975 so kernel should be the same, the only difference is that LS970 is CMDA, causing wifi issues on E975.

Viper ZVC is a stock based kernel with some very useful modifications: UC, OC, voltages control, faux gamma / audio and dynamic FSYNC.

Download from HERE
IMPORTANT: I will also upload a flashable recovery archieve with necessary modules to get wifi working, and modules_stock in case you restore LG stock boot.img

Known issues
  • max / min CPU freqs random reset (usually after reboot you have to set them back in trickster mod)
  • Strange LED behaviour (fixed using LightFlow with direct mode and root mode switched on)

Original thread: Viper ZVC
Enjoy more battery life and performance on your stock based ROM

Back up with CWM. In case there is anything wrong, you can do advanced restore and restore the boot.img. For now, we don't have stock kernel. I tried it and it is working. So far no issues.

I read somewhere that cpu frequency is 1.8 for default and even if reduced keeps jumpin to the highest value. The same for the gpu. Can someone check this?

True, this problem can be solved turning off mpdecision and activating freq lock. But 1.8ghz is really stable never had any issues and it hardly touch 1.8 with mpdecision on. (35h, only 9 minutes on 1.8)

You will have to use trickster mod to undervolt.

Can't install apps from playstore after flashing this kernel and modules fix. I'm getting error 403 or error 923 after reboot. Done factory reset...same errors occur. Tried on Savvy rom v5.1 and E97510b-CIS-XX 4.1.2 - MODv1.51

how to fix this?

Definetely the kernel has nothing to do with play store, so no ideea what causes your problem.
