Hello, my V20 boots into download mode and the only way to get the system started is to plug the USB port in and restart the phone using the volume keys+power.
Also I noticed that the the phone is not detected by the pc I connect to in the file transfer mode.
I don't know if both the issues are related to a problem in the USB port. I even opened the phone and gave it a cleanup with no result.
Thanks for helping me.
Tried a different battery? Remember having a similar problem which got fixed by changing the battery.

Yes It did indeed, the V20 battery itself is recently replaced as well. I also tried an external power supply providing enough voltage and power.
It still says waiting for connection aka download mode.

You might want to try a kdz, who knows?

The problem is it is AT&T and there is not kdz available for that version. Also it is not detected in any flash tool. I assume there is something wrong with the board. BTW I have never owned an LG with no major issue in its hardware especially in their board. That's a shame for a giant company like LG. Even cheap Chinese ones make flawless hardware.

If you press on the cable right near the microusb location (to insure there's no "wiggling" around in the socket), does it charge properly?
If it's not, it might be some weird combination ROM/flash/phone and I suggest you switch back to a stock ROM and see.

To me it looks as the firmware is screwed up. You should try and reflash. Probably stock.

I'm out of ideas, so you should probably ask in the custom rom thread for help (last you flashed).
can be due to a USB connector short.

My focus had the same issue. Vibrates, gives sound, screen comes on. I searched on google and found out it is a hardware issue. The pin inside the charge port might be too close to the corner. Check it. Solution: Use a sharp pin to pull it back to middle. It worked for me.. You can give it a try.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
So the problem is the following: my nex 4 has suddenly stopped charging..it was 2 days ago.The strange part is that when the system runs i can't charge the phone.It looks like the phone recognizes that i put the usb cable into it,but it shows the no charging sign on the battery history menu point (and the battery is discharging).And the twist is: when the phone is fully off and i put the usb into it it charges normally(white accu on black screen)but as soon as i turn on,it stops.
I did hard reset many times...Im on stock 4.3(unlocked bootloader,no root)
I changed the cable.No progress
I use a converter cause here in Hungary we have a two pin system,but this is nothing cause it has always worked.
Btw,the phone runs normally.
Any ideas?
First,I would like to get a solution,not a "RMA it answer",it would be the last option.
Thank you for your time.
My first thought would be to try a wireless charger.

If you have tried a full hard reset then its probably a hardware issue, not a software one. Try a different charger anyways, that could be it. Or like you've said, RMA or if your feeling brave you can open the phone up to see if anything battery related is loose/disconnected

Yes this was my first thought too.I just wanted to stay away from this thing,it's a little bit tricky when the phone is from England and I'm a thousand km away.But looks like I have no choice.Thanks for the confirmation.Any thoughts about the RMA?Will they repair it?Or Changing it?

You can try. Ring up google in hungary and see if they will do it. Otherwise you would have to find someone you know in the uk to return it.
One other thing, have you tried charging from a pc, not the mains? You could try that

Hi, I Do think the converter does not meet the specifications, if your device is off it generates just enough power to trigger the charge-regulator in your nexus4 and the phone is charging; if it is switched on, the phone drains so much power from your battery and/or charging unit that there is not enough voltage/mA-Load to switch the charge-regulator in your nexus4 to "On". The power provided by a converter is no sinus wave, it has irregular spikes and waves and this might over the time-being has "weakened" your Nexus- Charger or the charging controller in your phone.. Try another converter/charger combination if possible with a converter with pure sinus-wave output.
By "Hard reset" do you mean a "factory reset"?
I have an issue when the phone temporarily stopped charging, but it was a particular rom.
You can try buying a charging board replacement from ebay: http://www.ebay.com/sch/?_nkw=nexus%204%20usb%20charging%20replacement

This. If you just went into settings and hit factory reset, it just wipes data, not the system. Try downloading the google images (Or wait for the KitKat OTA)

So the only choice is to replace "insides", thanks for help. I'll use my country's auction site a lot cheaper

Yes i think the problem is the flash (ROM) chip. It is on motherboard so yes you must replace "insides". And i am sorry for your phone.:crying:
Have you tried to uninstall the drivers for the phone? And if your computer is Asus, do you have an app called Asus usb charger or something like that?
I had a problem with an Iphone which was not recognized by Itunes. And the device manager was going crazy, bcs the computer kept switching off the connection with the phone. It turned out there was an Asus app, called Asus usb charger or something like that, which was causing the problem.
So, check everything on your PC and find out why the connection keep getting switched off, format your memory card with SD formatter and after that try to flash it with Windows 6.5.
Best of luck!

Hi,
I have a Samsung Galaxy Note 4 N910F.
Suddenly, literally out of nothing it died.
No reaction when trying to power it on, no reaction when trying to charge it. nothing, literally NOTHING. (Also tried different chargers, sockets, cables, and 2 different batteries)
ALSO CANT GET INTO DOWNLOAD MODE BY POWER+VOLUME UP OR DOWN+HOME.
I did NOT root the phone, i did not use cheap chargers, everything was/is stock.
When i connect my Note 4 to my laptop, and go to device manager, it finds: QHSUSB_BULK
I dont know if it is bricked because i didnt do anything weird with the phone.
QUESTION 1: IF MY LAPTOP FINDS THE NOTE 4 AS "QHSUSB_BULK", IS IT NECCESSARILY BRICKED?
QUESTION 2: IF IT IS BRICKED, IS THERE AN UNBRICK YET?
QUESTION 3: IF THERE IS NO UNBRICK, WILL A MOTHERBOARD REPLACEMENT DO THE JOB?

Seen it, its not a solution.
In that case a new Note 4 may be necessary or take it to a Samsung repair centre.
I posted yesterday that my phone was going weird
Today it is in exactly the same situation as yours. Sucks that I have now to pay to take it to a repair centre when you can see a trend here. Really sad and frustrated. Mine is the Canada version N910W .
Qhusb_bulk cannot be fixed by PC... just a gsm service. I do this almost everyday with octopus box. Only qhusb_dliad can be made from pc with the help of sdcard.

Hi all,
Have just started to connect my device so i can pull the patched boot image for my thread and it won't see the computer, tried on several laptops and nothing, no adb, no fastboot.
It charges just fine but does not show the android usb system notification.
Really annoyed by this as i'm kind of stuck.
I'm on 7.7 but on a custom ROM / Evo X 5.9.1, doesn't look like anyone else has this issue besides me, have seen the odd user complaining about the same thing but haven't seen any fixes come up], if anyone has any ideas then i'd be grateful to get your two cents.
Will test MSM but it's not looking good, fearing a return to oneplus as i do have a good unit with none of the issues anyones ever listed like green screen and overheating problems.
It's usually me helping others but this time i need you guys help

Aye I've cleaned it up mate.
Tried different cables, I think EDL mode is working.
Means I could maybe return to OOS but it wouldn't let me back up..
Shame, I'm just downloading MSM now... Really annoyed..will give the usb socket another clean

Yea I'm dreading it being hardware. Never had this issue on OOS.
I think it may be Evo X but I don't know.
Bad luck I guess
Cheers anyway.
So MSM did indeed work, it's booting now, obviously couldn't back up any of the info on the device so i'm super annoyed at that but so long as usb connectivity works then i'll be happy with that.
USB Connectivity does NOT work now so i CAN connect to EDL mode but not normal usb conenctivity.
Anyone have any ideas???
Cannot root, install anything via ADB or even delete apps via ADB. Shocking problem to have man
I'm RMA'ing my phone, just getting it set up now.
Very painful process, they absolutely need the purchase order for warranty, things have changed with 1+
3-10 days apparently, used to be 5 when i've sent it in the past.
On connecting a USB hub i can read USB sticks and i can control my phone with an xbox pad??
Am i missing something? How is all this working yet i can't mount my phone?
Best bet, probably you broke the charging port. did you by any chance use like force usb charging like that?

I did use the force USB charging yes.. wishing I hadn't now..
I also connected to a usb-c to hub to connect a screen.
Issues kind of started after that.
Physically I haven't damaged it from movement. But could be from the forced charging
UPDATE:
Erm ok this is confusing???
I just connected my phone to a charger that is clearly not rated for it, in the hope it would shock the device, i then connected my phone and made a cup of tea, when i got back my phone showed me this (screenshot attached)
??? Lol what the hell? I've already booked my RMA lmfao
anyway, i shall keep an eye on it, i'll thoroughly test it and get it back up and running.
Strange, very strange.
