[Q] P350 fastboot bricked

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.

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?

I'm using Windows XP Proffesionall, all the other usb devices at least give a message if my PC can't recognize them. You know that yellow box that pops out saying device malfuctioned or smthing like that.

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

I understand. I'm just asking if you really using right boarddiag (thread that I mentioned - willcracker.rar)
Also be sure that you have a phone connected to right port (check it in device manager)

You have to use the original LG usb cable. Dont try with fake china cables because its a lot possible to have troubles with them.

charge your battery full and insert it
after downloading emergency files WDRT looks for device usb connection so make it perfect
plug/unplug pc usb cable several time with 1min time interval with all ports one by on
also check cable of bottom USB board to main board .

The trick to shortcut 2 pins on mainboard...? exist?

Take the battery out, then plug it into computer via usb. WDRT should recognize it in emergency mode. About 3 seconds after it says 'flashing' insert battery. Or it might fail. Took me a few attempts on that one. WDRT should download the emergency files. Look in C:\ProgramData\Microsoft\Packages\RM-xxxx. X being the device name. emergency file is called 'emergency_flash_config.xml
Oh yeah, might need to enable 'hidden files' in Folder options. ProgramData a hidden folder

when my 925 went crazy i downloaded latest WDRT and tried..just got error all the time..then unstalled it and downloaded the NOKIA version of WDRT...dident work either..then i reinstalled the latest WDRT without unistall the nokia verion...WHEN it worked for me

USE THIS AS STARTING POINT!!!
I once bricked a LG Leon and the solution to pc not recognizing the device was pinning the motherboard so the pc recognizes the qualcomm and you would be able to flash it, something like this:
Pinning

You need something like boardiag as shown in the video and some files to flash it, once you do the pinning and the pc recognizes the device, you will be able to flash it, you need some specific files. As far as i remember i had some folders with files with some LG models, G2, G3, etc... you need to find all the files compatibles with your device, i would suggest you first try everything to make it work without the pinning step, if you don't succeed then start thinking about this step, you can also try to do it without flashing the qualcomm, once your pc recognizes the device you might be able to recover it with WDRT without having to flash the qualcomm. Sadly, i cannot provide you with a full tutorial (including must dos if something goes wrong) because i don't have the required experience to do so.

my lumia 1320 phone is died

my lumia 1320 phone is died afer I tried to unlock bootloader with wp internal
its now There is no response to any screen response does not light up and there is no vibration and does not see the computer when its connecting with USB no any thing
plz help me

Sorry for late reply:
if it is still in that state, unscrew back cover (T4 Torque) and pull off battery. Wait some minutes. Click on battery. You should hopefully find your phone after reconnection as Qualcom Bulk device or even better in a defined state for recovery. By the way, which SBL3 file did you use for unlocking?
Best regards
Joachim

What is the model?
RM 994 or 996?

Did you remove and reconnect the battery? After that connect to your computer and check the device manager. Report if you see a device. Check also if your USB connector is physically clean (dust...).

I've done what I've been told and when I connect the phone to the computer this message appears (your device is not regonized) and I have a message in device manager (usb input device)

Have you installed the Windows Device Recovery Tool (for the drivers). Have you already tried a different USB cable, USB port, also a different computer with correct driver set?

Yes
Yes..Yes. yes

Did you already uninstall this USB input device (with drivers) and reboot the computer? We should come to a point where we have a Qualcomm device or a Nokia Emergency device or even a Lumia1320.
