I bricked my device too, then I done this,
Make sure all LGE drivers are installed in your computer then install msxml if you have installed already then Repair msxml
disable LGE Modem in device manager then start device in download_mdoe and in kdz updater, flash kdz with phone mode to =emergency
I hope this will help you.

Thanks to all of you! I entered into fastboot and I installed the 2.3! Now it works

How do I return to complete stock

Hello, what is the quickest way to return to complete stock coming from cm7?
you can flash original stock rom using, for example, smartflash.
See link here, post #37, to download the stock

stock roms vary depending on where and when you originally bought your o2x

And if you dont know which rom was for your region, just flash old v10b rom via nvflash and then do lg update. I did it two times for warranty repairs.

Yes, but I'm guessing it would be a rooted version of your stock rom.

You flashed wrong custom ROM or wrong firmware? If you flashed I9070P firmware on I9070 phone - your phone is hardbricked. Maybe something like this can help you: http://forum.xda-developers.com/showthread.php?t=2701363
P.S. Now I see that on that link is question, not a guide...
Anyway tell what exactly did you do.

Are you sure you own an Samsung Galaxy GT-I9070 Advance?
And if you can not enter in DM, then you may consider to donate your phone to devs for experiments.

Installing custom ROM from recovery shouldn't touch part where are part with Download mode. Try to pull out battery and retry. What happen when you try to charge the phone?
Tried many times to enter download and recovery mode..switched battery out and in...but it just boot normally and stuck on bootlogo...charging is not a problem...it charges normally...with a charging animation....

Can I Upgrade to JB?

Hi,
I have rooted ICS on my 4x HD. No custom recovery or unlocked boot loader. Is it possible to upgrade to official stock JB? I can't update via OTA, so would flashing the kdz work even though I am rooted? Thanks in advance, I just want to be clear before I go ahead.

Can I use the official LG Mobile Support Tool?

You could try. Connect your phone and using that tool try to force an update (somewhere in the upper right menu's). If that method leaves you on ICS, you'll have to flash JB yourself via kdz. Search the forum a bit for more on that.
