Hello everyone I've got an issue with my Nexus 4 which is why I registered, as I simply don't know what to do anymore.
My Nexus 4 is not recognized via USB at all, there is no connection sound and ist does not appear in the device manager.
It is charging and does show USB charging if I tap the battery icon.
Things I tried:
Uninstall/Install Driver with and without WugFresh Toolkit (USBDeview)
different Pcs (different USB Ports)
different USB cables which all worked with other mobile devices such as Samsung S3/4/5 mini
checking and unchecking MTP,PTP and Usb debugging
fastbootmode
factory reset
replaced the USB flex cable as i figured it would be defect
I tried to root it with some of the apps available bur none of them work with LMY48T.
I think it might be firmware related but because I didn't flash a Custom Recovery the last time I rooted it I have no possibility to flash another rom.
The root access was lost when the last OTA Update arrived which is why I can't install a custom recovery via the clockworkmod Rom Manager.
The Pc I'm working with is running on Win 10 I'm running out of ideas.
Please help me, thank you

Hi guys,
I have a massive problem.
I recently updated to 4.3 rooted etc, after a few days of not using my nexus 7 on the pc I wanted to flash a new rom.
Now my N7 is only shown as an "Unknown Device" in my Device Manager.
I tried to deinstall Drivers, install, everything, I tried every possibilty in Wug's toolkit, nothing worked. I also tried it on another Notebook where i have never connected any mobile device, same message and i'm not able to install the drivers.
I also tried several ports and cables(the original one included)
Here is the message:http://i.imgur.com/tgxOeZQ.jpg
Translation: The optimal driver software for your device is already installed.
After this I flashed back to 4.2.2 (downloaded the rom on my N7) while performing a normal factory reset, I can't wipe everything because then I am not able to flash anything.
So after flashing to 4.2.2 my N7 was shown as a portable device in my device-manager. I then turned on USB-Debugging to stock+unroot, it was then shown again as a Unknown device, in both modes, USB-Debugging turned Off and On.
So now my question, is there a solution to this? I searched for possibilites to get back to stock without USB but most of them were a bit sketchy or had dead links. Please help me (sorry for my bad english)
Edit:
I just the cable of my old Motorola Defy, and it randomly connects and disconnects(still shown as unknown), so basically I think it is possible that my USB plug is broken(it takes about 6 hours to load the battery which I think might be as well a reason for a broken USB plug).
But to send it back to Google I need to Stock Unroot first so here my problem is again!
greetings
... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426
Sent from my Nexus 5 using XDA Free mobile app
Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...
hello
i have a problem with my g928f
my issue is that it can not be regognized by the windows
i have tried at my desktop with win 10 and at my laptop with windows 7 and at both says unknown device,
i have tried everything i know of
unistall everything from the pc regarding samsung drivers
install it again , nothing
install smart switch , nothing
install kies, nothing
run odin , not even see the phone at download mode
made factory reset from recovery , nothing
charge is working just fine both from pc and my wall charger
i tried mhl hdmi and nothing happened

just a week ago i was using it just fine with my pc
should i take it to a store to check my micro usb port??
noone??
today i replaced the screen with a new one witch had a new usb dock on it and the problem is still here
i can not connect it to any pc.
i cann't flash the stock rom because odin is not see it also
is it possible to be a rom problem????
i can't flash the stock one because of the usb issue
but i think i can download another lollipop rom to give it a try.
Have you made sure that it is set as MTP?
Setting - Storage - USB.
Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.
sideload is not working either
usb is brand new and original.
is there a way to flash stock rom via recovery?
Hi guys !
I'm having a strange issue with my S4 i9505. It was running lollipop 5.0.1 Imperium Rom V5.0 (XXUHOD7) and it stopped prompting for MTP-USB notification in notification panel. When i connect the phone, it says me it is charging. I'm using windows 8.1 pro x64 + Genuine Samsung USB cable (which came with the phone) between my S4 and the PC.
Then i tried dialing *#0808# in phone app and choose MTP+ADB in USB connection option when the phone was connected to the computer. Nothing happened even if i tried other USB modes (like MTP, Rndis, PTP...). USB internet sharing didn't work either. Changing USB cables and USB ports on the pc didn't change anything either
So i did a factory reset under Philz CWM recovery and flashed an updated version of Imperium Rom v14.0.
USB-MTP was still not working even with *#0808# trick.
So i decided to install Samsung drivers and try a complete stock flash with XXUHOF2 Firmware from Sammobile.com with ODIN v3.09. When the phone was into Download Mode, I connected it via USB and it showed up on ODIN with no problem and then I flashed XXUHOF2 Stock firmware with no errors and no problems at all. The phone rebooted normally and the PASS message appeard in ODIN after ~10 mins.
But the problem still remains, even if flashing a full up to date stock rom with Modem/BL/System + factory reset. The phone still doesn't show into windows as MTP device even with *#0808#.
So i'm wondering if my USB connector is faulty ? Is it possible to be able to flash through ODIN with no problem and not being able to have MTP USB connection ?
I think ODIN flashes phones using Data +/- pins on the USB connector just as MTP do, so they might be good on my S4. May i be wrong ? Is it possible there is an electronic chip behind USB connector of my phone which is misbehaving preventing MTP to work but allowing ODIN to work ?
Do you guys have an explanation of this and do you think replacing USB connector of my S4 would solve the problem ?
I hope my explanations are good and you can help me

Try disabling and enabling USB debugging while the phone is connected.

I have the exact same probleme... Odin work but no mtp....Have you found a solution ?
Hi All
I am looking for an update.zip file I can use to flash the stock 6.0.1 rom again over my existing version to fix a USB connection issue. I need a Samsung OTA update.zip which can be flashed from the stock recovery via an sd card.
This has come to light as I've recently tried to update my note 4 to nougat but came across an issue where the phone will not connect with my PC via USB. I have tried all the usual tricks on the phone (dev options, usb debugging, MTP+ADB etc) but nothing was working. In the end I have replaced the micro usb daughter board on the phone thinking there must be an issue with the data pins but the phone still refuses to connect but charges fine. Strangely the phone thinks it's connected fine but the PC says it is not getting a device descriptor response. I have checked drivers etc and also tried 3 other PCs all of which connect to my old S4 without issue. I have also tried various USB cables including a new genuine samsung one.
Due to not being able to connect to a PC in any mode (such as odin download mode or recovery) and having the stock recovery without root my only hope is that a new update.zip will sort out corruption from the last OTA update. I believe this may be the reason as I was able to connect fine until the most recent update a couple of weeks ago. I have tried using a zip from the samfirm downloader but the recovery failed immediately with 'unable to map file'
Any help you guys can give would be greatly appreciated as I really don't want to be stuck on Marshmallow now Samsung will no longer be updating the Note 4.
I have tried connecting in MTP mode, odin download and recovery mode with usb debug both on and off
Many Thanks
Luke
