Official Rooting Process LG Lucid Fixed:
Let me just first start off by thanking all of the developers for all of there hard work in writing all the these programs that make it so easy for all of us to work on, fix and modify all of our phones and devices.
I did not write any of these procedures, or programs, i will just expand on what others have already done here. If at all possible donate to those who do all the work.
You will need a set of programs downloaded on your pc to flash your device to the next to last final update. I believe the the final update is: ics 4.0.4 or VS840ZV8_05.S8_05.P58016.R5
What you need is: converted to:
For whatever reason the latest final update for ics 4.04 for LG Lucid, has a locked bootloader, will not root, it frezzes and fails every time, at least i couldnt get it and this is how i did it.
How to force phone into download mode: Pull battery Put battery back in/ Volume up+down at the same time plug usb cable into phone port to pc, wait for it to virbrate a couple of seconds, and boom your in.
Note: recovery mode is not the same as download mode, keep that in mind when flashing the os. Flashing custom roms, nandroid recovery, and nandroid backups you will need to be in recovery mode.
Also make sure your pc is reading you phone before hitting the upgrade button or flashing will fail.
In order to get the cab file for the Original LG Firmware you will need you will have to obtain the Original LG Firmware.exe program from xda developers.
Instructions to convert the cab to a KDZ and flashing it: AKA UNBRICK
1.Make sure drivers are installed
2.Connect your phone to the computer in "Download Mode"
3.Open and extract to a folder
4.Install msxml.msi
5.Disable antivirus software
6.Open UpTestEX_mod2_marwin.exe
7.Wait for the program to open
8.Look for "Encrypt cab file to kdz file"
9.Click the folder icon
10.Choose the location of the cab you downloaded for VS840 firmware
11.Encrypt cab -> kdz Program will freeze up. DO NOT EXIT until program says Done!!! Otherwise it won't finish converting.
12.Close program
13.Open KDZ_FW_UPD.exe
14."Type" choose CDMA
15.Choose in "Phonemode": Emergency
16.Click the folder icon and choose the kdz file that UpTestEX_mod2_marwin.exe just made.
17.Click Launch software update and enjoy!

18. Once you have completed this procedure you can go on to rooting your phone using Root_with_Restore_by_Bin4ry_v15_(2).7z exe If you do not plan on rooting you can skip the rest of this turtorial and update using the ota ( over the air) method or you can use the KDZ_FW_UPD.exe and convert the latest firmware update to kdz and re- flash your phone to the latest upgrade. Or you can use the LG Program B2CAppSetup.exe Have fun either way.
19. Once the terminal comes up click on #1 for normal mode and follow the instructions. Dont worry about the code it asks you to put in, just click restore phone when it asks you to and wait for it to reboot.
Note: I will not be posting any links or mirrors. you will have to find them on your own. It is very easy to find all of the usb divers for the device and all of the software you need on xda developers web site. Or just google it.
My advise to you is to get all of the rooting files from xda, because there is a Root_with_Restore_by_Bin4ry_v15_(2).7z exe from google that is a downloadable program that simply put is a virus, the program you need is a noninstalable standalone program that opens a terminal. Just be careful where you get your stuff from.

SOURCE: My LG chocolate VX8550 phone fail to complete power up/boot up

I have seen that so many time on liquid damaged chocoloates. It's called power cycling. unfortunately there is not a whole lot you can do unless you can take the phone apart and clean it with technical spray. That may or may not help.
Another trick I have heard of is putting your phone without the battery in a bowl of rice and putting it on top of the refrigerator for about a week. I heard that works about half of the time though.

SOURCE: phone shuts off

if you droped the Vu than you could have damaged the insides and that might cause the repeating of it shuting off but a easyer way to get music onto your Vu is to get a Micro SD and get an adaptor for it and put music on that and then plug the SD into your phone its alot easyer and faster than useing the cord

hope this helps

Shows 99% won't open and can't shut down

You can first try doing what's called doing a Soft Reset. It's the first and preferred method to try as you don't lose any files or settings. Hold the power button until the Nook turns itself off. In most cases that will be twenty seconds or more. Then turn the power back on by holding the power button down for about two seconds. Hopefully this will allow you to complete a normal boot process. The second and more dramatic way to get a working Nook back is what's called doing a Hard Reset. This process will put your Nook back to "Just Out of the Box" mode. You will lose any files and settings stored internally inside the Nook itself. The good part in all this is it won't touch anything stored externally on your external SD Cards. To do a Hard Reset Turn the NOOK off completely. Hold the Power button and Home (n) buttons. The device will turn on. Continue to hold both buttons until the device shuts off once again (~15-20 seconds). Turn the device on normally. It will prompt for a factory reset. Press the Home button twice to confirm. ------- The important part in the above is to be sure you start the Nook via holding down both the power button and the Home (n) buttons at the very same time and keep them both pressed down until the Nook turns itself off.

Battery not recognised/not charging

Turn the computer off, unplug it, take the battery out. Then hold the power button down for 10 - 15 seconds. Plug the ac adapter back in, but do not put the battery in yet. Boot the computer, then shut it back down. Put the battery back in then boot it again. It should recognize the system now.

Lg lucid screen went black

Remove your battery, and leave it out for a minute or so, put it all back together, and charge... it may look lie it isn't, but since this phone seems not to have an LED the navigation buttons are your only indicators of trouble(pure speculation).
Your battery is probably depleted. i found out the hard way that a Droid X won't charge it properly... hope this helps

Powers up for 1 to 2 seconds shuts itself off

probably a boot loop, hold down the f8 key when you turn it on untill you see a boot menu and select "safe mode", if you can get it to start there, you should be able to shut it down and have it start normaly the next time. if not hold down f8 again and select "last known good configuration". if it still continues to loop after that, you will have to reinstall windows.
