Default [SOLVED] [Q] (Soft?) Bricked my LG MS769, KDZ flash with LG software not connecting

Hello, I shall do my best to shortly and concisely lay out my difficulties. (It was a bad decision to try to install a custom ROM on the Monday before finals)

I was looking to put a custom ROM on my phone, and was following this guide. I put CWM on my phone via this method. I had the ROM I wanted on my SD card. I boot into CWM, wipe the davlek cache like a good little boy, wipe the system (yikes), and select the .zip I want. Nope, status 7 error, abort! Heart racing slightly, I quickly Google and find a nice solution. Problem! When I reboot back into CWM... there is no CWM, and I'm stuck with the useless stock recovery mode that literally does nothing but show a picture of a dead android on its side.

I'm having issues with the offline installer. I've tried both the automated method and doing it myself but really nothing seems to be getting around the fact that my computer doesn't want to talk to my windows 8 computer, or my friend's windows 7 computer.

Here's some log output:

Thank you for the reply.

What happens: I hold power and volume up after plugging in. Immediately I get a "USB device no recognized" in a bubble in the bottom right. A second later I get the S/W screen. I put the battery in. Start the program. If I switch windows it hangs. It gives me this:

Code:
 [R&D Test Tools Log File]

20:28:06 : Launching SW update  
20:28:06 : Unpacking KDZ   
20:29:00 : KDZ file extraced  
20:29:18 : Files were extracted.
20:29:18 : LGMobileDL Load.
20:29:19 : Port = 0
20:29:19 : Connecting to phone    
20:29:42 : PHONE WAS NOT FOUND!      
20:29:44 : ===FINISHED===

Hi not_so_optimustic, did you do this?

**Navigate to Update/Tools and there select upgrade recovery.
Just in case:
In the own tool you have an option for install the drivers, you could try it.
Cheers . Good luck.

Sorry for the delay. I have found some more time to try to fix it this weekend.

I am not sure what this part refers to:

Quote:
**Navigate to Update/Tools and there select emergency recovery software.
There is no such menu visible in B2CAppSetup.exe that I can see.

Other oddities:
  • I was wrong about my phone model. it is actually an LG L9 MS769, not a P769. I don't know if that matters.
  • The B2CAppSetup.exe interface looks VERY different on my friends computer as opposed to mine. (see the attached screenshot) I am in the process of going through the motions on her computer to see if I get different results. However after opening the app and selecting my phone model and letting it install the drivers, I unplug and plug the USB cable again (staying in S/W mode), and nothing interesting happens beyond the circling "connecting" icon.

Let me know what you think. I'll keep trying.

I feel like I'm getting close! After installing the drivers, both the "Start Upgrade" and "Install USB Driver" buttons are greyed out. A message assures me that "Your device has the latest software available from the LG Mobile Support Tool", although this is clearly not true.

After clicking on the dropdown menu in the top right and selecting "Upgrade Recovery" it pops open the window pictured in the screenshot and attempts to download the software. This window stops progress at the download stage where the timer is frozen at 15 seconds.

Default Reinstall recovery image through fastboot

I managed to mess my L9 up several times before getting the bootloader unlocked, and one of the ways I got out of it was getting into fastboot using this method: http://forum.xda-developers.com/show....php?t=2119090 and then using fastboot commands to re-flash recovery, as described here: http://wiki.cyanogenmod.org/w/Templa...stall_fastboot (step 6). You can find recovery img files in the second post on this thread: http://forum.xda-developers.com/show....php?t=2623222

If you can get into recovery again then you can flash a new rom, if I've understood your problem correctly. Good luck!

I flashed the recovery (successfully?). My next confusion is how to boot into it. My device now shows the LG logo at boot and "Security Error" underneath.
