THIS GUIDE IS NOT FINISHED BEING WRITTEN AS OF YET, PLEASE DO NOT COMMENT!
Okay, it's the weekend, got alot going on... Will continue work on this thread Monday.
<3 MadSci.Alright, so since I have this wonderful space by accident, I figured I'd make perfect use of it by writing a little reference guide for everyone who knows nothing about the Xperia PLAYs out there. Why, again? Because being seasoned in T-Mobile Sidekick 4G Android Development / Modding didn't help me one bit.
N00B Reference Guide (yay!)
ROOTING:
This is when you give yourself "super user" permissions to make wonderful changes to your phone.
HOW TO ROOT:
Original Thread Here.
Download DooMLoRD's Easy Rooting Toolkit.
Extract the toolkit anywhere.
Enable USB Debugging.
Enable Unknown Sources.
Plug phone into USB cable and USB cable into computer.
Let Windows Update download the drivers, or install them yourself (will link here later).
Execute "runme.bat".
Follow on-screen instructions.
CLOCKWORKMOD RECOVERY: This is a handy tool that allows you to write wonderful things to the phone, such as zip files packed with themes, mods, ROMs, etc. Also handy, it allows you to backup and restore your phone.
HOW TO INSTALL CLOCKWORKMOD RECOVERY:
Original Thread Here.
Download ClockWorkMod Recovery 5.0.2.6 Easy Installation.
Extract the toolkit anywhere.
Enable USB Debugging.
Enable Unknown Sources.
Plug phone into USB cable and USB cable into computer.
Let Windows Update download the drivers, or install them yourself (will link here later).
Execute "install-cwm1.cmd".
Follow on-screen instructions.
FASTBOOT: This is a mode that you can put the phone into by holding the search key and plugging the phone into a USB port while the phone is powered off. This is the feature that saves your butt when you screw up by allowing you to use a command line interface to push files and commands to the phone. Do NOT toy with this unless you're sure you understand the instructions and are willing to risk bricking your phone... also pray that you never mess up your ability to enter this mode.
HOW TO FASTBOOT:
Download Fastboot package.
Download phone drivers.
BOOTLOADER: This is what starts before Android OS, and tells the phone how to do so.
UNLOCKING THE BOOTLOADER: You need to do this so that you can flash different kernels to the phone, which bring better features and allow better ROMs.
HOW TO UNLOCK THE BOOT LOADER: If you're phone is a model R800X (Verizon Wireless, United States), you're screwed (will update this later). If your phone ISN'T a model R800X, follow the instructions here.
Reserved Space.
Will sell this space for one million dollars
So I used ROMmanager to get clockwork recovery mode. Now when my phone entered the recovery mode it just say:
"Fastboot mode started"
"udc_start()"
If i connect my USB cable to it it says --suspend--
Now i tried using KDZ_FW_UPD in Emergency mode to restore original firmware but it cant find the phone. The log is:
[R&D Test Tools Log File]
10:50:59 : Launching SW update
10:50:59 : Unpacking KDZ
10:51:14 : KDZ file extraced
10:51:17 : Files were extracted.
10:51:17 : LGMobileDL Load.
10:51:17 : Port = -1
10:51:17 : Connecting to phone
10:51:17 : PHONE WAS NOT FOUND!
10:51:19 : ===FINISHED===
I tried this procedure on 2 pcs but no luck. It seems that my phone can't connect to PC with usb cable.
I installed LG Moblie United drivers and disabled the lg modem thing in device manager. I am using Windows xp Proffesional SP3.
So does anyone has any clue what I am doing wrong ? If u need more info just ask.
Maybe if I try from some linux distro it will detect my phone ? But what tools to use then ?
Use fastboot to recover the phone. Check the wiki at the Troubleshooting section.
---------- Post added at 03:31 PM ---------- Previous post was at 03:12 PM ----------
I recommend using drivers latest version. Last time I checked, United Mobile Driver was version 3.7.2 release 4.9.8.1 and Modem Link Driver was 1.0. I'm providing links for download from my personal Dropbox folder because I don't remember from which LG site I downloaded them from.

i had the same problem few days back... (ROM Manager sucks).... ok.. so.. before connecting the phone to the PC.. remove the battery, press both the volume keys (no need to press the power button)... and connect the usb.. now the cell phone will be in emergency mode.. try launching the software with kdz updater now... it should detect it.. after its detected.. connect back the battery (without disconnecting the USb cord ofcourse)... hope this works.. good luck
Good tip, adding to wiki later...

Didn't I said i did that ? My PC wont recognize my phone in fastboot or emergency mode, with fastboot being stuck at udc_start() and when i connect USB it says "-- suspend --" ,
I tried this guide madmanzrocks still dont see phone.
deleted lg modem, reinstalled all usb hubs, tried 10 versions of LGunited drivers, used both official update tool and kdz nothing works(can't detect phone), and also tried from cmd.
My problem isn't how to unbrick but rather why my pc won't recognize my phone :/
So, no feedback (USB Device connected sound) when conneting the phone? I assume you have tried all ports available.... Long shot, but maybe the phone's USB connector is dead... You have some background on electronics? If so, you can follow the service manual I reposted recently at the General section to check if the connector is gone (p. 113).

yeah tried all ports, I¨ll try on several other pc's. no connection sound, but phone is charging. I have quite some background on electronics so ill check it out when i try this on couple others pc's. Don't want to dissaemble it quite yet and if it rly is dead repair will probably take more money then i spent to buy it(I got it 2nd hand for around 50 $). It happened before that my PC coudn't recognize some devices but never like this. I ussualy get device not recognized, malfuctioned or smthing like that .

as I mentioned the same problem was solved bu connecting the cell phone with the battery removed. But if even that doesnt works for you, then maybe there is a fault in your PC. Does your PC instantly recognizes USB Pendrives? And which OS are you using?

Hey, i have the same problem, and i also can' t fix it, i tried all ways, but my pc dont detect my phone... so i hope that someone will find a way how to fix it... but it' s not normal what is happening with this phone...
Don't know if it helps or you already tried it.
Start fastboot v2 and start the flash so it waiting for device.
Then plug in usb and start phone in fastboot.
That worked for me before.

I can try.
First start fastboot v2 on your computer.
Load the recoveryimage amonra or cwm5 (not cwm6)
Start flash so it say searching for device.(or something like that)
Plug in usb in computer.
Start your phone in fastboot.
Plug in usb in phone.
If that don't work you can try to instead of start phone first start it with usb cable.
Can need to unplug usb and plug it in a few times if the device say suspend.
Hope it helps.

Can you please add the links to this files or the files? I would be very thanksful...
Up to this point i tried all the methods you guys told me and some i found myself. Nothing worked for me as my PC stil won't recognize my phone, I have also tried all this methods on 4 PCs(2 had windows XP Proffesional SP3 with all the updates, and 2 had Windows 7 SP1 with all the current updates installed(note that 1 version was 32-bit and other was 64-bit).
My conclusion is that the USB connector is DEAD, even thought i can still charge my phone trough it. I probably won't be trying to fix this anymore as I've found an 4th gen iPod and i'll be using that from now on.It is true that i can't make calls(at least not the standard way, you know, it doesn't support SIM cards), but i have my old dumbphone phone for that and this will be used for just about anything else.
So thanks to all of you guys that tried to help me but i fear this is unrepairable. If anyone want's this phone I'll give it to you for free so you can have some fun cracking your head to see what is wrong . I only ask that if you find a way to fix it you post it here and notify me about it(send me pm).Otherwise do whatever you with it.
I have solution

There is no direct way that I know of run the lg mobile support tool to return your phone to stock and then start the guide over. This time take a look for my post regarding the kdz error under windows 7 and my solution.

Ok try this in this order:
1. Un-install the LG drivers and the LG support tool.
2. Reboot the computer.
3. Reinstall the LG drivers and LG support tool.
4. Reboot the computer.
5. Plug the phone back into the computer.
6. Wait for windows to finished installing all drivers (usually about 15 min or so).
7. Right click on the P930_UDT_v18f_04112012.exe and select "run as administrator".
8. If you are still having issues try a different USB cable or USB port.
Edit: One more thing that just occurred to me. This error can also be generated by too low of battery. But since the phone doesn't charge in download mode I would recommend powering the phone off and charging on AC before proceeding.

Just to piggy-back on that:
* DON'T use a USB Hub to connect your phone to your PC...ALWAYS directly connect whenever possible.
* If your touch-buttons are flashing, you're battery is low and you WILL have problems (I found this out the HARD way). Makes sure you're using a charged battery...As already stated, Download Mode DEPLETES your battery (irregardless of it being connected to a PC).
Good luck!
I tried that and it still didn't work...The battery is charged, I tried a different usb cable and its directly plugged in the pc
well I fixed it ....It might have been stupidity on my and probably was...But anyways When I ran the KDZ I never let it finish because of the error it would show but it still flashed afterwards. But at least people will know now to ignore the KDZ DLL error
Hi there
I have accidentally close the LG Flash Tool while the program is flashing my phone
And now, the phone stays in black screen and keeps in download mode
When i try to flash the phone using LG Flash Tool again with TOT/ universal DLL
It seems that the phone has lost PID, IMEI, Phone Model, SWversion information, therefore the flash will not run
I have googled for half day but can't find any answer, Pls HELP!!!

Your best bet would be to use LG software tool. You will get the rom at the factory setting and you will have to root the phone again (if you so desire). The tools and drivers can be downloaded from the link below. Once you install the tools on a PC, just plug in your phone with USB drive and follow the prompts. Here is the link for the tools:
http://www.mylgphones.com/lg-software-tools-download
Good luck!!
Nope no solution. Motherboard is corrupted. Use your warranty and get the phone RMA'd
Thanks for reply
The phone has been repaired by a professional
There is no any soldering required, and done by shorting two pins on the board, and flash with qhusb USB interface
Quiet simple way to repair
All imei/other info exists

Can you boot to recovery? Should be the power + volume down combo until the logo comes up.
Alternatively,
Have you installed ADB and fastboot drivers?
Can ADB see your device when you're plugged into the computer? Perhaps you can get into bootloader mode through ADB if so.
Connect LG G4 to your computer.
On the PC, access the Android SDK folder (download it if you don't have it).
There, open a command prompt window by pressing shift + right click on any blank area.
In the CMD window, execute the command " adb reboot bootloader " without quotes. If you haven't enabled USB debugging, you may be out of luck.
Tried but not working
Hello, Friend Thank you very much for your time and efforts while typing this to help me out. I did but still doesn't recognize took the owner. Technically the phone is dead.

1. Point us to that dubious unlock app please!
2. Very very often an issue occurs because a user do not use the correct commands or important error messages are thrown and the user do not show. So please write EXACTLY what you do. For example the exact command to proof the connection (e.g. "adb devices") and the exact result. easiest and best way is to just make a screenshot of anything.
3. Another example is how to you try to get into download mode? There are some guides which do not work so explain what you do always helps others to help you.
I use the following method:
Pull out battery
Plugin USB cable connected to the pc
Press vol Up and keep pressed while putting battery back in place
4. To avoid driver issues you should consider to use FWUL ( https://tinyurl.com/FWULatXDA ) for anything else then kdz flashing (this requires windows)

Hi, Thank you very much for taking your time and energy to answer me. I used Z3x to Factory the LG G4 (T-Mobile) I wanted to flash it by downgrading before to see if it could work. this is how I break the phone with the downgrading. So now the phone is not recognizing by the computer as Modem when I plugged in, I see it only as External Drive.
