Bleh just got my Optimus yesterday, came stock with zv9. Decided to root today and had no trouble, flashed TWRP recovery using FreeGee then updated to the newest TWRP version using GooManager. Made a backup using TWRP then used GooManager to download Lifeless ROM. Just downloaded, didn't flash. After the download was done I shut off my Optimus but when I went to restart it, it powered on, showed the LG logo for half a second then just went to a black screen. Can't boot to recovery. Whenever I try and turn the phone off it just restarts again showing the logo for brief period of time then black. Any ideas? It's gotta be bricked but I just don't understand how or why. Probably going to try and take the battery out and see what happens.

okay well your not bricked if you can get even a little life like an LG screen. hook phone up to computer and use adb to get into bootloader and try to reflash the recovery img again. it just sounds like you need to reflash your recovery. thats why it didnt flash. lemme know. ill keep checking back on the thread for awhile

Okay perfect I appreciate it. Downloading SDK right now, I'm away from my desktop and didn't have it on my lappy. LG has a program similar to ODIN too right? Would that maybe work as well?
You would need LGNPST. you can find it in the IRC if you can get to download mode you can flash back to stock and start over.

Just because the screen doesn't come on don't think the phone is off. Plug that sucker in. If you see the logo you should be able to get in download mode. Also, if the phone is on, you will eventually see some green android screen.
The same thing happened to my phone once. I only know of one way to hard brick this phone. I am not telling anyone how. But, I doubt you did that. It isn't something you would accidentally do.

It's on but it just shows a flat black screen. No matter how long it is on it doesn't get passed that. Also, when it's plugged in there aren't any charging lights. Not sure what to do since adb doesn't recognize it.

You are going to have to pull the battery.

I had manually loaded ICS 4.0.3 but didn't like it and tried to go back to 3.5. I used the unlock ROM that's been floating around here for awhile. When it was done installing I re-booted, the "SAMSUNG" logo came up and then screen goes blank. Only way to turn phone off is to pull battery.
I can get into Samsung recovery mode but when I try factory reset it tells me cache/recovery files cannot be found.
Any help on a solution would be appreciated.
Fortunately I have a friend at corporate or I'd really be screwed. He can get me a new phone but I'd like to try and fix this one as it's my fault.

Likely bricked. Do you have flashing notification and capacitive lights? Have you LGNPST'd? If yes to both of those questions, you're in the same predicament as I was and hopefully you have insurance, because your phone is fried.

Because your phone doesn't know if it needs to be in charging mode or booting. Pulling battery will fix it.
Sent from my LG-LS970 using xda app-developers app
I had a similar problem as you. Upon getting the phone I rooted and used the FreeGee app from the Google Play store to unlock the bootloader. Everything seemed fine and dandy, until one day when I let my phone's battery drain completely. Pluggin it in to a wall charger resulted in the failed boot where the LG logo flashes before going to a blank, but backlit screen. Luckily, the first few times this happened, through a combination of quickly plugging and unplugging the usb cord and holding the volume up+power button, I could get it into recovery (TWRP). Then a simple cache & dalvik cache wipe, and the phone would boot up as if nothing ever happened. Very strange.
Well yesterday this happened again, however, this time there was no getting the phone into recovery. My previous methods of button mashing and plugging and unplugging weren't working. So, I decided to bite the bullet and use LGNPST to get back to ZV7. Now, like you mentioned, this failed boot would automatically happen, without pressing the power button to turn it on. So it was difficult to get the phone to stay off. I found that with the phone unplugged, if you continue to press the power button until the blank backlit screen turns off, AND continue to hold the power button for an additional five seconds, the phone would stay off and not auto power on into the failed boot.
Once I was able to get the phone to stay off, I pressed the middle of the volume key to depress both volume up and down, and then plugged a usb cord that was attached to my computer. This powered on the phone into download mode. Following the LGNPST guide I was able to get to around 67% complete before my phone turned off and an error message flashed on the computer screen telling me to power cycle the phone and reconnect. Well, the whole 67%/85% LGNPST failure is apparently common and not indicative of an actual failure; HOWEVER, my phone became completely unresponsive. It wouldn't power on at all. It didn't matter if the usb was unplugged or connected to the computer or wall charger. So, I was forced to unplug the battery. I followed this tutorial and successfully disconnected and reconnected the battery cord, and the phone shot back to life. It even booted up into the factory stock ZV7 rom. I guess that LGNPST was successful. It looked like I was on my way to returning my phone to breezy's deodexed ZV9 stock rom that I was previously running.
I went ahead and re-rooted, ran the FreeGee app again, and rebooted into recovery. Then I made a backup and attempted to flash my new rom. Now, I think this is where I royally screwed up. I was pleasantly surprised to see my screen layout and all of my settings still intact after LGNPST back to ZV7 and thought I could just wipe the caches and ignore the factory reset and system wipe before flashing. Perhaps it was this, but part of me also thinks there might be something wrong with my battery draining extremely fast in recovery.
I proceeded to flash and all seemed good, but rebooting resulted in the LG logo failed boot that we have already discussed. So, I went ahead and repeated the LGNPST-re-root process numerous times (switching to the freegee 0.5 batch file instead of the app). Everytime after the first initial restore, I could never get my phone to enter recovery. As soon as I rebooted after using freegee, the phone would be soft bricked again. Sometimes I would get the LG logo thing, other times I would get the dreaded alternating flashing red notification light and soft keys. A battery pull was usually required in these circumstances before I could get back into download mode to start all over.
I was about ready to give up when I took to the LGOG irc channel. That's when Xboxfanj stepped in and helped me out IMMENSELY. Over the course of several hours, he walked me through flashing some partitions in ADB. At times it seemed like there was no hope and that I should have just returned the phone, but he failed to acquiesce, we pushed forth trying a couple of other bootloader options. The new bootloader appeared to have fixed the phones erratic behavior with powering on and off, but I had no rom to boot into and no recovery. Xboxfanj recommended using fastboot to flash over a recovery. Once in the new bootloader screen my Windows XP machine detected new hardware and wanted some drivers. I attempted to use the [ADB/FB/APX Driver] Universal Naked Driver 0.72, but XP indicated that I was missing 'winusbcoinstaller2.dll'.
I grabbed winusbcoinstaller2.dll from here and all was good. Fastboot recognized the phone, I was able to flash recovery and subsequently boot into recovery. From there I reformatted the system, wiped data/factory restore, wiped cache, wiped dalvik cache, and flashed breezy's ZV9 deodexed rom.
Fortunately, after around 7 hours, I am happy to say my phone is back to being rooted, unlocked, and running ZV9. It powers on and off properly and can get into recovery without a hitch. I'm still curious what will happen if I let my battery drain completely. Perhaps I'll try it some time this week. I'll be sure to post back here if/when I do that. All in all, it was a harrowing, but educational experience.
Anyway, just wanted to give a big THANK YOU to Xboxfanj! You really are the man :good:. Thanks for your patience and determination.

Hello guys !
I have done something terrible and phone is not booting up part recovery now.
I had rooted the phone with one-click universal method without any hasstles and then try to reboot into bootloader by pressing VolDown+Power button.
Eventually ended up rebooting in original android recovery. I tried rebooting with option in that but it was not responding.
While trying it out, I mistakenly wiped cache partition.
Now NO MATTER WHAT COMBINATION I TRY, phone doesn't boot up past the recovery.
Please help me sort out this mess. I need to sell the phone.

I wipe my cache partition all the time. I am rooted but still locked (I don't think that will last much longer). Anyways, in the android recovery with jelly bean, I found that you no longer use the power button for selecting or confirming. It's now done using the menu button below your screen (on the right) . At least that's how it works for my phone.
I hope this works for you.

Mate.. after getting the phone booted up I installed FreeGee app from Play store to get bootloader unlocked and flash recovery , but downloading recovery stopped due to an error. So I rebooted the phone and since then Wifi is not detecting my home wifi network.
I then tried to do erase cache partition and even factory reset but nothing helped.
Do u know what else I can do to get it right ?

I haven't fully unlocked my phone yet. Only rooted it. However it sounds like you might have to LGNPST to set things right. Maybe someone else that is more knowledgeable with this issue could chime in and correct me if I'm wrong, but I think that might be your only option.

Thanks mate.. will try this
OK.. mate I tried the LGNPST method. Downloaded LGNPST and stock v9 bin file. Used it to flash the stock rom back to stock.
howvere even after full completion of the process without any errors , the phone stucks at LG logo forever. I have tried the process twice.
Is there something I might have missed. I followed the instruction to the line from the pastebin link. Do we have a different Dll for the stock rom then whats there in the LGNPST repository named LS970_LGNPST.dll or something ?
Hopefully this will get you going.
If you downgraded from ZVB to ZV9 heres some needed info:
If you're stuck at the 4glte screen: To get to stock recovery - Power off phone. You need to hold power button for about 20 sec to get it to turn off. Then press and hold vol down+power - The LG logo will come on, then the capacitive lights. Immediatly let go when the capacitive lights turn on.
It takes a few seconds to work. Data wipe/Factory reset. Reboot.
And if you happen to reboot into recovery after this upgrade? Use the "menu" button on the led lights (far right when holding it) to get it to accept your commands. power button won't work.

If that doesn't work try this.
Get into DL mode and run "teeny bin" from the post I sent you to, to get LGNPST. Try the main one first, then the optional one if it still doesn't get you into TWRP. You just might have one of those "haunted phones" that seem to be poping up.

Thanks again mate.. I was able to install Teeny bin and then flashed a AOSP rom. Now I have my wifi working again without any issues.
Do u have a link of any stock based rooted deodexed rom for this ? I don't want to flash bin images via LGNPST but want the stock look and feel
Imperium and Lifeless are our only 2 stock ROMs so far. In the Development section. Both are very nice.

Another tip when putting the phone into download mode would be removing the battery before pressing the necessary keys.. Once the dl prompt appears battery maybe reinserted back
ok thanks for the help, but ill have to do this after i get back from work. pulling a grave yard shift tonight.

oh by the way, just to add, while phone is of, simultaneously press the power key and the middle part of the volume keys, with the battery removed. Then insert the usb cable. That should do the trick. Good luck!

You are in CWM boot loop. You don't have to take the lg flash tool.
There are some simple method to fix it.
try this method if your PC could recognize your phone.

If you could not get it to work, flash TWRP to your phone, then use the TWRP method in this post

Please make sure you already have a rom installed in the phone!

Nice new sig, BTW
ok so im back from work and i gave the cmd method a whirl but no luck at all. I went ahead and continued with the TOT and it actually worked. I dont mind at all that i have lost root, im sure some one will figure that out. But what does this mean? Did i just brought back to life a bricked phone? if it is, it would be my first time. I have never bricked a phone in my life and this time it was not by my doing. Im just glad to be part of this community where one might not now it all but everyone working together and helping each other can get things done. Thank you all that helped me out! cheers!!!!
