[Q] Lg optimus one p500 can't bootup stuck at lg logo - Optimus One, P500, V General

Help, i stuck at LG logo and can't bootup ,i try everything,holding power buton home buton volume down ,up etc. with only usb cabel without battery and still nothing,today i take my lg o. one at my lg service,and im waiting on answer., I had 2.2.2 froyo and after tutorial from cyanogen mod site with topic:LG Optimus-One Complete Flashing Guide" i succesefly insttaled CyanogenMod 7.2.0-RC1-p500,so today i wanted to try CM 9 or is4 beta4 from this thread:[UNOFFICIAL][DEV/GEEKS-ONLY] Cyanogenmod 9 (Android 4.0.3)[BETA4][KANG TEST BUILD]
" , and just as i started , i enter in rom manager ,enter in clockworkmode and when asked,i hit lg optimus one option instead lg optimus one oldbb , so clockwork installed and in rom manager i enter in recovery., and than start this big , nervous problem of mine, my phone is stuck at lg logo and can't bootup when i pressed power buton ., is the problem in that DJOptimus-One mention in his tutorial,i quote "5) Press the “Flash Clockworkmod Recovery” option
6) Popup appears, asking for your device; select “LGE Optimus One”
7) Another popup will appear giving two options for the basebands:
- LG Optimus One (This is for new baseband)
- LG Optimus One (Old BB) (This is for old baseband)
I would advise you to select Old BB recovery as its more stable; new baseband may result in semi-brick (Personal Experience) " )
??!

Flash a stock firmware using KDZ while in Emergency Mode (Back+VolUp+Power).
There are a few tutorials on the O1 section on how to do this.
I believe this happened because you installed a recovery for the new BB when you had the old BB. If you want CM9, flash a stock 2.3.3, that will also install the new baseband on your phone.

In addition to the above, once you get it resolved, don't forget to use Rom Manager to create a back up of your existing ROM, so that you can flash it back in cases like the one you're currently in. I've been thankful a few times that I had a back up to fall back on.

11:41:57 : Unpacking KDZ
11:41:59 : KDZ file extraced
11:42:00 : Files were extracted.

In kdz select emergency instead of diag
And boot into emergency
Power+vol up+back
