Hi,
I did this too, I had to do it file by file. So first flash the fls (CP baseband file). After that the phone will turn off. Start it in update mode and then install the AP (rom) file. It worked for me. I used smartflash.
I don't know why, but the phone turned off after CP flash and it didn't start again, which lead to timeout error.

Nope, no need to go back to stock, just boot into S/W update and go.

Maybe try to flash any rom with SmartFlash
1.Take out battery
2.replace battery
3.hold Vol- (volume down button) AND power button together until you see the recovery menu. then scroll to Cm updater file and reflash -or- clockwork mod file and flash from backup.
No way!!
When i tried Smartflash pc not found com ports. so i cant flash with this way.
also i tried (JAZZMAN's advice) power and vol- to enter CWM menu but i cant see any thing. (my phone not open)

How phone must show bootloader or you have installed already CWM it must boot into CWM, if it doesn't show your phone to the service .

If you really did everything and in a right way, you can start to build a new house because you have the first brick already.But...it's not so easy to brick a phone with SFT.If you really followed the rules for Smart Flash Tool it's practically impossible.I know that people tend to panic in such situations and do something wrong in a rush.Well, take the battery, sim card and memory card out of the phone; hold the volume up button and then plug your usb cable( sure that cable and contacts are okay ), which is pluged in your computer with SFT opened; sometimes the phone enters in s/w mode in a second but sometimes needs five.Then flash a GB rom or anything you want.If nothing will happen is very much possible that you have a hardware problem( something similar happened to me when my motherboard was fu.ked and this is quite common with P970 ).Good luck.:fingers-crossed:
P.S. Are you talking about SE arc or LGE P970?

Did you maybe flash a wrong ROM? Double check please. Whats the name of your kdz file? Where did you get it from? Did you interupt the update procedure? Or did it get interrupted?

Are you sure you used the v10G for P970? Cause otherwise only and interruption could cause such a hard failure...

Well, the phone goes in bootloop when you flash patched files with recovery and then forget to flash Superuser.You must not boot your phone when it enters in recovery after flashing with SFT but flash Superuser from your SD card first.I think that this maybe was your first problem.But LG logo and flashing leds are also a very possible sign for a faulty motherboard.The same happened to me with one week old P970 with official firmware and not rooted, when I tried just to reboot the thing.And if your phone died after this, you can be 99.9% sure that you have a fu.ked motherboard.
Is it possible to make a downgrade to my rom só i can restart to use new cm nightlies

I dont think you can just downgrade with smartflash tools. V30 has a locked ICS bootloader if im correct and apparently my O2X bootlooped when i did that. Now i stuck and even NVFLASH fails
i downgraded my v28g to v20s with smartflash
Thats the answer....
Use Nvflash i downgraded many times from v28a,g,v30a down to v20 or cyanogen mod Its the savest way.
Im form germany... only found the german forum but the zips of nvflash work very well use it:

I think it might be time for me to throw away my P990 because im not sure if the VOL UP button actually works or is it the PC problem.

Anyway although I doubt smartflash could work for my case, I decided to give it try and flash V20B rom (starhub) via the .fls and .bin files method. It gave me an error when it was about to partition the "7 partitions". So i exited and unplug my phone as the SW upgrade screen on my phone turned to a blank screen. I wanted to try again and plug back holding the VOL DOWN button to enter SW mode. I heard the Windows sound notification (when a device is plugged or unplugged) as i do so but the screen was still blank. So i checked the device manager screen and saw that i entered the NVFLASH recovery mode.
Im confused as to how it would work now but anyway i was grateful to your post and that made me give smartflash a try still. :laugh::good:
the easiest way in your situation is using this [TOOL] Full Brick Repair (Clean & Easy)
It's nvflashable and already includes a CM10 nightly. Boot it up and upgrade CM10 with the built in upgrader. That's what I did yesterday. Then boot into recovery and flash gapps.

I'm using LG Optimus EX Su880.
Sorry when creat this thread here because i'm not found any thread or box support su880
Please help me about this problem;
I try installing recovery on my phone :
----flash 2.3 KDZ via NVFlash-----> Root by EXroot -----> install exrecovery apk via file manager
Then i open recovery app & select [ Reboot recovery ], Phone reboot into LG logo and stuck... Phone only can connect APX mode. cannot S/W mode.
I use P990 All In One Toolbox to Extract KDZ file. I have got img files ( bootloader.img, recovery.img...)
I use NVflash to flash img files but nothing is hapen. Cannot open S/W mode
I think Su880 & 990 is same. Hope you help me save my phone. Thank you very much !
