OK Background-
rooted running ics zv9
worked perfectly until i decided lets try and get cmd 10.1 on here
backed up everything and ran the .zip in recovery mode
phone restarted and stuck at black screen(with backlight)
I can turn it on and off but the only screens that i can get to show up are:
Download Mode
FastBootMode
Blackscreen (backlight)
and Off

ive tried the kdz Updater,
in 3GQCT Type and CS_EMERGENCY AND EMERGENCY PhoneMode
I get an Upgrade Error wParam=100, lParam=72

ive tried lg mobile update...
Says Update is not available

I dont know what else to try or so... im really upset with myself that i did this.

Please help me people!!! Thank You

Can no one help me?! I managed to get recovery mode running again so now i have Black screen, Download Mode Fastboot mode and recovery... Im trying to see if i flash another (compatible) ROM if itll actually let me use the phone because unbricking it isnt working. Does anyone know what the error WParam 100 LParam 72 means?! Thanks :/

[GianPo]

Flashing Lifeless Rom now.

[GianPo]

So yeah so idk if anyone cares but problem solved its even faster than stock rom. I highly recommend LifeLess

Solved by self lol

Glad you got it working. Yeah, don't flash an AOSP ROM on a phone that isn't supported.
Additionally, you can use LGNPST tool to revert to stock ZV7 as long as you can get into Download Mode.
Don't ask for a link, as we're not allowed to link directly to it. You can, however, find out more about it on the IRC channel (look in the Sprint Optimus G XDA forums)

How were you able to load the recovery back onto the phone? I'm having that issue now. I have the lifeless ROM but I'm having a hard time getting the zip file onto the phone so I can load it. Please help.

[Matt Thomas2]

[ryan gregory]
