I'm currently using a P769 model with JB, and it's never been rooted. I remember the phone was 100% charged when I looked at it three days ago and I didn't use it at all the day after that, but when I tried to use it yesterday it didn't turn on and it hasn't been responding since (I did try to charge it a few times). Actually the exact same thing happened a few months ago but it fixed itself in a few hours, but this time it's been two days and I hope it doesn't mean my phone is completely bricked The main thing is that I want to avoid doing a factory reset if at all possible since I made the mistake of not creating a backup.
I've tried some recovery tools (LG Mobile Support along with third-party) but the problem is that nothing seems to recognize my phone as connected. Weirdly enough, when I plug it in it without the battery, it connects and disconnects continuously (the device manager refreshes itself every 3-4 seconds); I've updated the USB drivers and everything, but nothing seems to work. Not sure what the Recovery Mode key combination is but I'm assuming the phone has to boot first for Recovery Mode to even be accessible anyway, so that's probably out of the question. However I have tried Vol+, power and Vol+, power, home, and nothing happens.
To make the recovery software recognize your phone,you must put it in S/W mode by disconnecting your phone,taking out the battery,reinserting the battery and then,while holding the volume+ button,plugging it into your computer(keep holding volume+ until the screen says S/W just to be safe).At least that's what I always did.
Hmm... I tried that, and nothing happens on my phone, but I get a popup from the system tray on my computer that says "USB device not recognized: The last USB device you connected to this computer malfunctioned, and Windows does not recognize it" which appears and disappears repeatedly. It appears that no software can recognize the phone as connected at this point. I think it might be a random battery failure but I don't know how to tell D:
The thing is all I really need out of the phone is the contact and app data if possible, which is why I'm so hesitant to do a hard reset :| I read around and I'm assuming what I should do is to flash the bootloader but I'm not sure how to go about doing that since I'm getting zero response from the phone itself.....
UPDATE: Tried a hard reset anyway, but still nothing from the phone. I attempted fastboot, however, I don't know how to make it work since "OMAP4430" does appear under TI Devices in Device Manager plus an "Unknown USB [device failed enumeration something something]" under USB Controllers, but that's it.... nothing appears under Other Devices, which seems to be where the bricked phone should show up. adb doesn't seem to recognize it either.
i have the same problem with my lg p760.
any solutions?
you had a solution for this problem ?

Hi All,
So, I tried to flash Cyanogen mod last night using the instructions here: http://wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide. I was coming from a BIONIX ROM that flashed fine.
Anyways, the phone went into a reboot loop in the recovery screen and I foolishly just held the power button until it stopped. When I turned it back on it was broken. That is, now all it does is display the white Vibrant logo in the middle of the screen with the smaller Samsung logo below it. If I hold the power button for about 8 seconds the screen goes black for about 2 seconds and then comes right back up to where it was. I can't seem to even turn the phone off any more. It just stays on that screen permanently unless I hold the power button, in which case the screen is off for 2 out of every 10 seconds. Yanking the battery of course turns it off, but putting it back in immediately returns it to the state I've described.
I've scoured these forums and tried every button press + battery state + cable state + SD card/SIM state combo suggested, but the phone won't go to download or recovery mode. I found one thread describing the exact same problem. The OP said he'd try a jig and then disappeared without any further updates. I'm going to try to get my friend to make a jig using one of these sets of instructions
http://forum.xda-developers.com/showthread.php?t=819551
http://factoidz.com/how-to-unbrick-your-samsung-vibrant-galaxy-s/
but until then my questions is: does anyone have any experience with this problem (can't even turn the phone off)? If so, do you have any recommendations? Did a Jig work?
keep trying to get to download mode, pull battery, plug usb in to computer and to the phone, while holding both volume up and volume down pop in the battery. People have tried hundreds of times with it not working and then all of a sudden *bam* download mode.
So... my friend made me a jig and it works in that I can see the shoveling droid indicating download mode. However Heimdall/Odin won't recognize my phone. Heimdall's zadig utility won't locate the phone either, even with the cable plugged in. I'm, once again, stumped.
Just an update; I've tried Odin on three different computers, two Windows 7 (64 bit) and a Mac (with Heimdall). None of them seem to recognize the phone. Device manager on the Windows 7 machine does not update when I plug the phone in (in Download mode via the jig or not) and I can't find anything about Samsung in it anywhere. However I have installed the Samsung drivers; a few different sets I've found around the forums. I've also tried a couple utilities like the Vibrant toolbox and one click unbrick. Nothing seems to have any effect. I was so hopeful when the jig worked and got me to download mode, but now it's seeming I'm actually bricked. Has anyone seen a phone that could get to download mode but still be bricked? Oh, and I checked the cable using a friend's phone; her Mac recognized her phone using the cable. Haven't tried her phone on my Window's machines though.
Once again, any help is more than appreciated.
Have you tried to see if adb is working? If it does then try adb reboot recovery? If it works there is a file I can post for you later (is in my pc) that can restore your sbl.bin and fix your download mode problems.
Thanks for your help everyone, the problem was apparently resolved by a new cable; which is strange because the old one works for data transfers... just not for flashing apaprently. :S
I swapped my son my Droid 4 for his LG-VS700 and I attempted to root it yesterday but failed
It seems there's a lot of issues I'm having and not sure how to resolve them
For example the HARD RESET for the LG-VS700 is
-Press and hold the Power button+Home key+Volume down key simultaneously then release 3 seconds after the LG logo appears.
-Once the LG logo disappears, an Android logo will briefly appear indicating that the reset is in process.
-The reset process may take up to 90 seconds to complete.
When I do this it shows the Android Logo and starts to reset then it reboots automatically and never resets
that's one issue
another one is the USB Debugging
On the Droid I could turn that off and on. It did not matter if it were plugged into the laptop or not. Is it normal that the USB Debugging option be "Greyed out" when the device is plugged into the Laptop?
I've tried every which way to get the laptop to recognize the device but it never shows on on my adb list in cmd prompt and every guide I've tried to use doesn't work because it seems nothing is detecting the device
I've updated with the latest drivers and installed the android sdk tools like many guides have suggested. I think once I've actually gotten the little debug icon to show up on my device screen in the upper corner but now it only shows the USB icon and charges.
I've tried several USB plugs incase it was the plug .. I've ensured all software was up to date. I've actually installed and uninstalled software over and over thinking it just didn't install properly
These are very odd errors to me that I've not seen before and cannot find answers to
1. Hard Reset not working properly (reboots instantly on the Android Logo)
2. USB Debugging being "Greyed out"
3. Device just not being detected by Laptop even with updated software
After an unsuccessful CWM flashing attempt, my phone it getting the infamous "SECURITY ERROR" message. Now, I tried the offline KDZ method, but like many other JB users, the flashing got stuck at 15%. So, finally I decided to use the online flashing method using the new LG Support Tool. But the sad part is that I am suffering from a low battery issue.
So, does anyone know how to charge a soft bricked Optimus L9?
Any help would be highly appreciated.
I'm just guessing but you could try removing battery for 15-20 sec then inserting it and connecting your phone to charger. If that doesn't work, try installing x and u using fastboot that try same process with removing battery...
You can always use another phone to charge your battery

I tried the fastboot method too, but I face a problem while doing it. The OAMP device which shows in the devices manager keeps disconnecting and reconnecting. So then I unplugged the USB and clicked on "show hidden devices" and then installed the drivers by clicking on the OAMP shown there. But when I plug in the USB again, the same reconnecting starts happening. Do you know a solution to this?
You should follow this post...
Connecting and disconnecting of OMAP device is normal, but it is important that it's recognized in device manager...
FINALLY UNBRICKED....
Sincere thanks to all those wonderful people who have made so many tutorials. I failed to do the offline KDZ flash as well as the fastboot method (as I have mentioned above). But anyway, I did unbrick my phone. I flashed using the online method as follows:
Download the latest LG Mobile Support Tool.
Connect your phone in "Software Upgrade" mode (by holding the Vol UP button while connecting the USB).
In the LG Tool, click on "Options > Recovery". Getting the recovery to open is a confusing task. You have to fiddle around with the USB Drivers options a bit.
Now, let the LG Tool do it's magic [In my case, it downloaded a 592MB file]
CAUTION: When the upgrade tool is in it's last stage, the phone will restart at around 93%. When it restarts, you quickly need to press and hold the Vol UP button to again enter the "Software Upgrade" mode, otherwise the upgrade will not succeed and you will get an error. If you get that error message, don't worry, the Tool will tell you how to "RETRY" (don't worry, no file will be downloaded from the internet this time )
REGARDING THE BATTERY ISSUE:
When my phone got bricked it was at around 65%. Now, when I finally unbricked it, I am seeing 83%!! So, either the phone charged when it was connected in the "Software Upgrade" mode, or it charged when I plugged the charger in the wall socket for half an hour. In any case, if your battery is dead (and phone is bricked) try to charge using a wall socket first. When you do this, the phone will automatically switch on and you will again get that sad "SECURITY ERROR" message. Just switch off the phone when you get this. Let the phone be plugged in for some time to let it charge. [NOW I AM NOT SAYING THAT IT WILL CHARGE AS I HAVE MENTIONED THE TWO POSSIBLE WAYS ABOVE, but hey, it's worth a try!] If your phone switches on, good job! Otherwise, try to charge via the USB by connecting to your PC/Laptop by going into "Software Upgrade" mode.
I just hope that the above points will help some unlucky soul who was stuck like me Remember, never give up!
Thanks to all for the tips my optimus was running fine at about 65 percent charged and just shut off. I bought a new battery charged all night in the wall still nothing. I can't get my computer to see it. when i hold power and vol down I can hear the computer make sounds like it recognizes it though

Can you enter s/w upgrade mode? ( Press and hold VolumeUP button and insert USB cable into phone )

I don't think so, just now did it and I can here the computer making sounds like it recognizes it but nothing shows on the phone
p.s. guessing my board went bad, no worries though just first time I ran into something I couldn't fix if the cpu would read it or any software I might have a chance
If you still have warranty you should take your phone to service, if not then try installing fastboot drives and flashing x and u then try offline kdz flash...

well I did the fastboot option i found but not sure if I did it right, I downloaded the omna files but not sure if the right ones but I did get the screen to show a faded out lg symbol not sure if that means anything
Use fastboot from here. You have here how to install fastboot drives. Then follow instructions from this page.
Read instructions carefully and you should be able to successfully unbrick your phone.
Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
I have a samsung galaxy s3 i9300! While i was sleeping, i was charging my phone and when i woke up the phone was stuck at the initial logo screen of samsung! Then, i tried to press the home bottom power and volume up bottom to reset while it was doing that it went back again to the logo screen before being able to choose wipe cache and stuff! I tried it several times! Then as i was searching through net i saw that odin thing custom Rom and i thought that maybe i should give it a try! So i tried to installed it by connecting my phone to the laptop but my pc did not identify my phone! Then I tried again by connecting and disconnecting the pc with my phone and while doing so i pushed the button of Repartition at Odin. My phone was not identified so i have no idea if that happened! Now my phone does not even open, or charging! Please tell me if there is a way to make it work again!
It might be of some help to mention that my charger is a new one that i bought from bol.com and its not the original one! I have no idea if that affected somehow the mobile functioning.
No, you are unlikely to fix that. You can try a usb jig, see if download mode will start, but it sounds like partial SDS followed by user panic until it was hard bricked.
If it didnt show in odin you have a driver issue and the repartition wouldn't have happened.
Remove battery, sd and sim. Make sure the battery is charged.
Insert battery and hold home+vol down while pressing power once.
If the screen lights up do not let go of home+vol down until it has entered download mode. If the phone wont light up at this point you have a bigger problem.
Once in download mode install the samsung mobile device drivers on your pc, you might need to try different versions, and plug the phone into the pc's usb on the motherboard. Try to avoid using front mounted or shared ports as they are unreliable. If your phone doesnt interact with your pc try other drivers.
