I tried rooting my L9 P769 earlier today.
I saw that I could unlock my bootloader for a faster rooting process, so I tried that.
I flashed to 10A from 20D, and that's when I got the wonky screen and reverse image.
From there I flashed to 10G and although the reverse image was gone I still had the wonky screen.
Now I've flashed back to 20D and I still have the wonky screen. I can't even get through the initial set up.
I've flashed and rooted phones before with no problem, so this is very discouraging to me. Please help
EDIT: Right after publishing this topic I thought of something. If there is a way to enable USB Debugging via the emergency call keypad, I can use the adb to fix the screen problem. I saw a fix for it earlier, after I had gotten myself into this bind. Is there a way to enable USB Debugging via the emergency call keypad?
Hello there,
I'm using a rooted LG Optimus 4X HD - P880 with the stock firmware. Or should I say I was using :crying:
Well everything started when I decided to flash some good looking roms into my rooted LG, I needed to unlock my bootloader so I did. ( I was using Os V20D_00 as I remembered but definitely a version newer than V20A_00) Everything was fine my phone got restarted and obviously then the Setup Wizard started.
That's ok till now. But after that, whenever I try to setup my phone, cause there's no way LG would let me access settings or any possible menu without setting it up, and "Unfortunately, LG Setup Wizard crushes " everytime I tried.
I should say that I have had uninstalled lg's base home launcher before (but replacing it with another app), and couple of google apps like hangouts and google plus. I never touched to G play or anything but I guess home launcher might be a/the problem, only guessing though and even if so I don't have the solution that's why I'm here :laugh:
I tried hard reset
I tried to reinstall stock firmware from using kdz V20A_00 and V10F_00 both
I tried to redo all rooting and unlocking bootloader processes. Yeah they work but the problem is I'm not able to flash any custom roms or gapps also cause my PC sees my phone only when it's on S/W Upgrade mode.. That to with no access to internal memory somehow, I can see its connected to LG Mobile Support Tool though.
So I'm pretty troubled right now. I wasn't using any recovery also.. (yeah, very noob thing to do, as I am kinda noob)
Device is on warranty but since I bugged my bootloader and all, I can forget about it if it needs to go and get fixed I guess..
So I would like to know if there is any solution that any of you knowledgeable gentlemans and ladies out there know..
I would be really glad if anyone can help me out.. :fingers-crossed:
Thank you.
Hey everyone,
I know there are countless threads on this but I've been up all night going through pages and pages of info and trying virtually everything that each post said to no avail, so I thought I'd just make a new thread and see if anyone can help me.
Okay, so, I had a rooted L9, with locked bootloader, on stock JB before I started any of this. Yesterday, I decided that I wanted to put Cyanogenmod 11 on it, yet, I have only managed to soft brick it.
Basically, it's stuck at the Security Error screen. I can get it into the S/W upgrade mode, however, when I do that and open the LG support tool the program just crashes. The Windows "not responding" error pops up, and the program closes. I have no idea why this is happening now, because the program was working fine before, but anyways, yeah. I have the shttps thing running in the background, and the connection is successful. I tried doing the offline fix countless times, but no luck. I have the UpTestEX_mod2_marwin.exe file, too, that I've been trying to use, however, as you all know, it just opens the lg program when you click on "upgrade start" and the program crashes. I tried doing the software upgrade through the exe file, but it doesn't find the port. Device Manager tells me the L9 is on port 9, but it looks on port 1 or 0, and doesn't find the L9.
I think that's basically it, and, if anyone can help me at all it would be very much appreciated (I don't really want to have to buy a new phone!)
If it is a security error than I think it would be easier to fix it from omap4boot mode with unofficial fastboot. Its a thread in this forum.

Hey, so I've looked through these forums, as well as google search, with every combination of words i could think of to address my issue, and so far nothing has worked. So im posting here, hoping y'all can help me.
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?
Hello,
I had a similar problem, offline method didnt worked for me saying that my device is not connected. Then I faund this tool on forum http://forum.xda-developers.com/showthread.php?t=2797190
Use it with described tutorial (use 3GQCT and DIAG) and you are going to unbrick your phone.
Ok, I'll give it a try when i have access to the neighbors laptop again. I'll post the results here. Fingers crossed, my phone is up and running again soon and I'll be able to post my results from my unbricked phone.
IT WORKED!!!!!
Holy hell, it worked! A week of searching and trying with no success, now my phone is up and running again! Thank you sooooooooooooo much! Can i get a solved tag?
You're welcome. I'm glad I could help
I bought the T-Mobile LG V10 off eBay. It was listed as a parts/repair phone cause the phone would keep rebooting and apps would crash.
A factory reset from the stock recovery those issues . Now I noticed there is no sound at all. Not even through headphones.
I have unlocked the bootloader but am having trouble flashing TWRP recovery. I keep getting a error right before it finishes.
Edit: I forgot to mention that the phone is on MM.
PS. Is there any other way to root this device?
Any ideas what could be going on?
TIA for any replies.
There's a dedicated T-Mobile LG V10 section.
