Hi, because with last update increased count of people with bricket phone, I just tryed search for way how to repair this phone. It seems, that last possible way how to save your phone is emergency mode.
I would like to notify you, that I didn't tested it (I'm had not luck enough to brick my phone yet ). I just searched and tried write this for help to others.
So, let's go on.
1) If it's not possible connect to phone via ADB (in Adroid SDK/tools run "adb shell") at all you will try next steps. If it will work, you can use another, verified tools like custom recovery or KDZ_FW_UPD (search on forum for more) [HOWTO] Flash original firmware on P500, )
2) If you fail in previous step, you can try enter into emergency mode manually and try to flash ROM with KDZ_FW_UPD:
Download KDZ updater and uncompress it
http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html
Install msxml.msi from the uncompressed directory
Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)
Turn phone off somehow (remove battery etc.)
Install drivers properly
Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
Install the LG drivers by selecting the update manager from the lg site
Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
Press and keep pressed "Volume up"+"Return" and connect USB cable to phone
Yellow screen with text emergency mode should appeared
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT (I have one report that CDMA mod works too)
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
I Recommend do not switch phone off. There was some people, which done it and after they were not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....
In KDZ file : Choose the ROM file you downloaded in the first step
Press Launch software update
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Make sure that all update was done successfully. Phone should restart itself automatically
Disconnect the USB cable from the phone
Press the three button combo for HW reset of device i.e volume up + home + power button
List to do based on Zecanilis's [HOWTO] Flash original firmware on P500
3) Still no success? Wait for more "What I can do" or just go to LG and let repair on them.

Please let me know if it works. I just searched for way and I haven't possibility to test this steps for now. I will do update if it will be necessary, same as I will try describe more about software which I founded.
Some experiences from thread(s):
AVanover5: ...It works if you set the mode to CDMA and DIAG. Just to let people know. Not sure if it'd work without the recovery screen or not. I never tried it ironically, haha. Thank you guys.
geejay2: ...Bricking seems to be easily achieved by forgetting to disable the LG Modem driver. Apparently the modem driver interferes during flashing. Also I noted that kdz is not stable under Win2k, I switched to WinXP to flash successfully. I saw several aborted flashing attempts in WinXP with modem driver enabled.
domenic_s:KDZ_FW_UPD doesn't work (Application cannot start) -.- Using Windows 7 64bit version. //edit: allright tried another pc (win xp 32bit) and yeah - it worked... I'm so happy.

About shaking (sorry, but I still can't believe... )
salte_eskil:wow! shaking the phone really worked! seems kind of stupid but thanks to you all at the xda forum for tips and tricks
4wd vege: Now unbricked. Strangely kdz updater only saw my phone after shaking!!!
me2kimi:It sound crazy to shake the phone while at emergency mode. I's crazy but it magic. ...So what I do is connect to usb, Launch software update at kdz while shaking the phone. Then after that kdz is working like normal.

I tried with all possible combination.. with and without battery.. vol- home, vol + return, power vol+ home.. end more.. but phone don't turn on...
In meantimes the phone is in the service LG.. hope...
Exscuse me for my English
Did you had phone off before trying this? And also battery should be charged. I just added this things...
If event that it not show you emergency mode, LG service and warranty is probably the only way how to proceed. Sorry. But I will be searching if another way will exist...
Good work .. I hope that you will find a way to solve ... especially for other users .. good luck
Good work @The_ERROR.
It should work. I think you should also add that the phone mode should be set to Emergency (and not DIAG as mentioned) in the kdz updater.
Moved to development and stickied it for a while!
Thank you!
Cheers

Good to know - do you know differences between CS_EMERGENCY and EMERGENCY?
Recovery Phone?!
Hello,
Had anyone tried "Recovery Phone" from the LGMobile Update app? It's under the "Customer Support" menu. Enter IMEI or S/N and see if it can bring it up to life.
Cheers.
Yes.. I tried.. but nothing.. the LG MOBILE UPDATE crashed because don't wiew the phone in Usb...

Not really. Gathered some info though. We use emergency mode when the phone boots into only emergency mode else we try CS emergency as last option.
In any case this method will work only if the kdz updater recognises the phone.

I was able to do the KDZ, actually thats the only way possible. Please add this to the list:
1. Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments.
2. Install the LG drivers by selecting the update manager from the lg site.
3. Disable the modem driver.
4. Once done, reboot the handset and when it has come to emergency mode connect it via USB.
5. Its going to detect it as usb drive. Launch KDZ. No need to go into Emergency mode.
6. shake the handset - IT DID WORKED FOR ME.
My suggestion don't give up. It took me around 14 hours to bring the handset back to original firmware and here I am today trying to boot the rom once again.
7. UPDATE AND ENJOY.

Thanks, I will do!! Only about 4 and five.
First reboot the handset and when it has come to emergency mode connect it via USB
and then
It's going to detect it as usb drive. Launch KDZ. No need to go into Emergency mode.
So, whats about if phone didn't go into emrgency itself (for example stuck on Android logo)?

I am talking about phone getting into Emergency mode, KDZ doesn't need to switch to CS_EMERGENCY or EMERGENCY Switch off the phone first, then you are either connect it to USB cable or you can remove it from the USB cable. Key combination to bring the phone only in emergency mode are:
1. Connected to USB cable, only thing visible is the LG logo, this is because its getting charged. Press VOL UP + BACK BUTTON
2. Not connected to USB cable and is not charging and so switched off: Press VOL UP + BACK BUTTON + POWER BUTTON
In both the cases phone will switch to a yellow screen showing: "Emergency mode!!" and will remain like that.
It's only in Emergency mode that the handset will be detected like a USB drive and can be KDZed.
I seriously doubt the "Shake your phone part". It just sounds so ...
Peace

OK, I edited it. But I kept possibilities of EMERGENCY and CS_EMERGENCY modes if standard way failed. About switch into emergency, I think that it does not matter which way for emergency is used.

Have you tried all the mentioned methods? Press the combination buttons a little longer (Maybe that can help).
BTW what did you do that bricked your phone?
1. The phone was connected to Powerbank and after disconnected can't turn on to stock rom.
2. When I click on I see only LG logo and after 5 minutes logo my cellphone provider.
3. I can turn on Factory reset but after I choose factory reset after next reboot still is bootloop.
4. I thought that I can turn on Download mode I hold volume up, plug in the cable, and I see text "Download mode" and it tells me to keep holding. after 1 min. nothing going on. I have seen on internet photos that download mode should look diffrent than mine.
5. When I'm in "download mode" after 2-3 min. it turns on fastboot.
6. I have installed LG Driver but my computer recognizes my phone as an USB charge only interface - Lg Flash Tool and LG PC Suite didn't see phone
Any suggestions ?

You can try installing google's driver and finding your device in adb, also check in device manager if your pc can even detect your phone
Unfortunately on my phone debug mode is turned off. I installed google drivers but Adb can't see my device.
My computer detect on my phone :
Modems: LGE AndroidNet Usb modem
Ports: LGE AndroidNet Usb serial port
Devices : Lge Android MTP Device
------------
Update
Finally I gave the phone so lg service and after few days They said that burned internal memory. Subject to close.

Hello guys,
I open a new post because I have not found solutions.
I attached and detached the USB cable and the battery several times to try to get into the S / W Upgrade mode.
Suddenly the phone screen is not turned on. I can no longer access the S / W Upgrade mode. I tried to connect it with the USB to the PC and detects it but after three seconds you disconnect, then again begins again and goes on for a couple of minutes until no longer be detected.
The PC tells me it can not recognize the device.
Someone what can you do?
Thanks and sorry for my bad English.
Hi Guys,
I'm in a bit of a problem. I bricked my phone and nothing seem to help.
Let me tell whats happened
1. I updated my TWRP in LeTV X500
2. This kinda made my phone to in soft brick mode every time I restarted it went to TWRP
3. I than installed new ROM from TWRP (i think it might be too high for my phone)
4. Phone endup bricked, not switching on, off nothing - redl light only
5. I tried here to install new rom from Windows and Linux via SP Flash Tools - phone is not recognised.
6. I disassembled the phone and detached battery
- now this is actually helped in a way that windows now recognises the phone, but the connection is not continous
- it recognises MediaTek Pre launcher ... few seconds pass
- it disconnets the MT Pre Launcher
- It recognises VCOM USB Port ... few seconds pass
- It disconnets again
- loop like this goes on and on
7. I tried holding any of the buttons (up, down, power and combination) - not helping
8. I believe my last option is to try and bridge some of the points on the motherboard to try and reset the system ... is this correct?
I have no idea what should I bridge with what ... there are no labels on the MB, i'm not even sure where the GND is.
Any ideas fellas?
Here is front of the MB:

Here is back of MB

help will be appreciated
Have you found a solution?
I have an old LG G Vista (VS880PP) without root, stock firmware android 5. For no reason, when turned on, fastboot mode began to load.
At first, the phone booted normally time to time (if pull out and insert the battery back), but now it doesn’t want to boot at all. I can't even charge that phone because of this...
It enters to the recovery mode without a problem, but it does not boot into the safe mode (it did it before I made a hard reset...). Deleting the cache/hard reset did not help.
It does not go to Download mode either. When I hold Volume+ and connect it via USB to PC, the pre-boot mode is displayed only.
When connected to a PC holding Volume+ but without a battery, the question mark in the charging silhouette shows up and that's it...
Installed:
- adb,
- LG mobile drivers
- LG PC Suite.
- LG Flash tool 2014.
But I can not install "LG mobile support tool" because the installation process hangs at 5% indefinitely (the same situation on a laptop with win 8.1).
