    Thanks. This is working out pretty good. My phone would lock up if I let the phone sleeps for a few minutes on the 800mV kernel. So I'm using the 850mV kernel and it seems to be pretty stable.

    My question about UV is just how it works. Anyone have any documentation about it? It just seems like feeding a chip less voltage than it was designed for is a bad idea that could have less than desirable consequences.

    The worst UV can do is reboot and crashes. If that happens, just do a nandroid restore. It's like what we do with PC's CPU.

    When you flashed the UV kernel did you also push the associated .ko file? That would cause the WiFi to not work if you didnt...

    if he flashed in from recovery using the zip, the .ko file is already where it needs to be (tested on mine)

    I do have one question if any of you here know, is it possible to mount /system to be seen on my computer? i selected the mount option from recovery but it does not see it, it only sees /sdcard when i select mount for that one.

    Anytime you Flash a Custom Kernel you Should ALSO Push the Associated .ko file. If you don't you Could Run into Problems. If you just flash a Kernal from recovery the .ko file STILL needs to be pushed.
