Help!

Just got my new Marquee and I think I may have already bricked it, I have been looking everywhere for a solution but am unable to find one.

I am stuck on LG screen. I am unable to get into CWM, and unable to connect via adb.

Here are some details of how i ended up here.

Phone was not upgraded yet so I rooted without an issue, had that set up for 1 day before I installed CWM and attempted to make a back up.

CWM got hung up on system during the back up for 45 mins.

I tried this again a few times with the same result.

Thinking my sd card was the problem and it was set up EXT4, I wiped and reformated my sd card as it still had partitions from my old replenish. I then tried CWM again, and BOOM, LG screen!
I had booted several times before this with no issues, not really sure why this would happen.
Thanks in advance.

Are you able to enter into emergency mode (download mode)?

I'm not sure how to enter into it, try (from powered off):
Hold Volume up and down and power button.

Thanks for the help!
Yes I can, but I can't get any of the tools within UPK to work properly. With LG mobile update, it gets stuck at 4%. With software update [kdz] I get error 52 and 100.
And I can't seem to locate the bin files for smartflash.

The phone is ON all of the time, unless the battery is not in it, always stuck at LG logo, or in emergency download mode

I actually have the bin, give me a couple of minutes to upload it.

Here you go:

Unzip the ZIP

Oh how I miss Odin...

So I am not sure, but is there another file i need for smartflash?
The How-to in UPK has a .fls in the CP bin box.

Any ideas?

I've never heard of nor used UPK.
Edit: try following this guide while in download mode:

And instead of DIAG, choose EMERGENCY.

If that doesn't work, try CDMA instead of QPST.

UPK is the name of the upgrade kit that is in that thread, I have tried every possible combo I can think of, with the exception of smartflash, which i need the .fls file.

Hmm, I think I saw a .fls when I extracted the cab. I'll look again to see if it was from the LS855 (I extract so much firmware from LG that I lose track of what's what lol).
