[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?

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

1. You need to do is to check the latest version for your phone here by entering your phone's IMEI code.
2. Keep in mind the version and country and download the KDZ file you need.
3. Install LG drivers on your PC.
4. Go to this thread and from the section How to flash ROM KDZ Method start from the 3rd step.
This video shows how to get into Download Mode.
Then you have to root your phone again.
good luck

Hi, mirko0. We have the same problem and we need to do the same procedures to find the solution.
As seen in the following links:
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
http://arena4g.com/forum/threads/unbrick-hard-unbrick-d855.7/ (Brazilian portuguese tutorial)
http://open-freax.fr/guide-unbrick-your-lg-g3/
You'll have to open up your phone (seriously) and make a short circuit in the board. Than, your PC will recognize as Qualcomm 9008.
Do not forget:
Install the x32 or x64 drives
If x64, do not forget to disable drive check
If windows 10, do not forget to reboot in advanced mode and disable drivers check
Everytime the phone reboot, you'll need to make the short circuit. I know, a pain in the ass.
You'll need the MBN folder of the Lollipop or Marshmallow. This is our actual problem
I haven't found the MBN folder of 6.0(v30) or 5.0 (v20), just v10. We'll need those files to proceed.

I finally had to send my phone for repair and I have repaired under warranty, soon expected to return repaired

All started when the phone isn't capable to install the official update to 6.0.
I decided to try other ROM's, opening the boot loader and installing the TWRP recovery. All goes well, but the ROM that are working better (Tomal - Discovery 2.00) had problems with my LTE networks.
Reading one of your post, I started to try to install the official 6.0, but I forgot to wipe the system before relock the bootloader.
After trying flash different RUU files through fastboot I used one from easy firmware: (0PFJIMG_A51_UL_K44_DESIRE_SENSE60_Orange_ES_1.28.75.5_Radio_01.01.010_U10305041_08.01.41222_2__combined_signed.zip) that belong to my CID (Orange Spain)
Then the phone don't respond to anything...
I will uninstall all drivers and programs and restart according your instructions...

Did you do this ?: 1.Android ADB driver https://yadi.sk/d/TVkbNcXv3KP7mQ Connect the phone to the computer in the Device Manager on the computer to choose the interface adb to install the driver specify in the manual on the desktop. 2.Also install USB_driver_QCOM https://yadi.sk/d/mrmvZKrk3MSggY 3.Connect your phone to your computer,оn the computer in Device Manager, click the tab ports (СОМ and LPT).What is written there?

I'm running Windows 10. As you know this OS not showing Ports (COM and LTE) in Device Manager. I added manually a COM port, (COM3 in this case), but appears only the yellow signal (!) related to errors.

I need help :(

Hi guys, my friend gave me his girlfriend's Mi A2 Lite because it does not work. I need your help.
The phone does not turn on, no fastboot mode, no recovery mode. It is stock, without customization (no custom rom, no custom recovery, locked bootloader). The only think it does, when i plug it to a pc through usb, the light starts blinking. The pc recognize it like "Qualcomm hs-usb qdloader 9008", that mean (i think) it is in edl mode, but if i try to flash a rom with miflash, it give me an error "cannot receive hello packet..."
Sorry for the long message, i hope you guys can help me. Thank you

It is probably problem with the rom you download (it needs to be tgz.file ) or you put wrong address of the file in mi flash program. Make sure to download rom from this link:
https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871 ( you need to extract this)
and just in case watch this video for beter understanding (2 and half minutes long) : https://www.youtube.com/watch?v=TdvAlb7cXvQ&t=55s

https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871 ( you need to extract this)
and just in case watch this video for beter understanding (2 and half minutes long) :
&t=55s
let me know if this works. Good luck.

I tried rom you linked me:
1st attempt: for few seconds status says "flashing", after that it changes in "ping target via firehose"; after about 80 seconds it gaves error.
2nd attempt: status says "can't receive hello packet" and give me error.
After these 2 attempts, pc does not recognize the phone at all. On device manager it says "unknown usb device" instead of Qualcomm HS-USB QDLoader 9008.
What can i try now?
Thank you

You didn't say why the phone is not working, maybe is hardware problem not software, anyways try to download drivers on pc to recognize phone, if that is not helping you probably need to buy new motherboard and replace it

The phone turn off by itself and stop working. I've updated driver on pc. I've to solve "ping target via firehose" problem on miflash.
There is any method to discharge battery even if the phone won't boot?
