My phone is the Lg optimus L9 p769 running FW v20h. I had it rooted, bootstrapped cwm recovery is installed and still accessible. Unfortunately for me, i had disabled usb debugging off. Cant remember why, but I did.
I was browsing around for build.prop tweaks, found a good list, and implemented a few. After reboot, everything was going smoothly, hell, faster and smoother than before, which i assume came from tweaking the build.prop. At that point, i chose to implement 1 more and be done. So i added the line and rebooted my phone. SOFT BRICK!!!!!
Now, as i said, ive done quite a bit of searching for a fix, including the offline fix and basic LG Support Tool restoration, but nothing is working. Offline fix says my phone is not connected. Online recovery says im already at the most recent FW available. Ive tried fastboot, but installing the u boot and x loader wont work. CMD doesnt recognize my phone when i try anything adb related (obviously, because usb debugging isnt enabled), nor does it recognize my phone as a fastboot device even with the phone displaying the mirrored logo and says fastboot v0.5 in the top right corner. Also, the bootstrap CWM wont mount my external SD, which has my build.prop backup on it.
So, basically, that what I've read into. A wall, so to speak. As a side note, my wife has the same phone with an unmodified build.prop. in fact, the only thing that i have done to hers is root it with the LGpwn app.
Now, is there anything i can do with this, other than throwing it against the pavement outside? While i think I'd get a sick satisfaction from that, it hardly solves my problem. Also, i called LG directly, but they won't help me at all without payment. Even with their CS rep saying it was their fault (because, of course, I'm not dumb enough to tell them I broke it by messing with the build.prop). However, the slight bit they did do remotely through the laptop had them going through the LG Service Tool.
Anyway, that's about it. It really is a great phone and i really would like to repair, rather than replace, it, but im stuck. Anyone got any ideas?
