Unable to have phone recognized as a device on any computer - Honor 8 Questions & Answers

Hello there! I posted in the N00B thread without any success and so am casting a wider net:
I have a rooted phone that's been working well for about 1.5 yrs and all of a sudden it's not able to connect to the computer via USB. It was working fine til about 3 months ago, no new apps or changes to the system as far as I know. It still charges when connecting to the computer but I don't get the prompt to choose the USB mode and the computer doesn't recognize it as any sort of device. I've tried it on several computers that have recognized it in the past without luck (drivers up to date) and have tried different USB cords.
I've gone to USB and developer settings and changed and restored default settings for USB connection as well as toggled a bunch of other settings in that section.
I've wiped the Cache and Davlik Cache several times.
I cleaned out the physical port. Any other thoughts? thanks!

If you are on windows 10 PC, the latest windows updates could be an issue. I faced the same issue with my computer. After rolling back windows update (or may be resetting the PC to default settings) has helped resolve my issue and i could connect my phone again normally. It is nothing to do with your phone as far as i know.

You said the drivers were up to date but you didn't say whether you tried completely uninstalling the drivers. If you didn't, uninstall every driver you can find related to the Honor, reboot and plug the phone back in. I'm running the absolute latest version of Windows 10 and have no problem connecting my wife's Honor 8.

Thanks for your suggestion - I did try rolling back the update without benefit. Also, to reiterate - this is not being recognized by several computers (including a Mac) and that leads me to believe that it's the phone that's the source of the issue. I don't even get the USB menu (Charging, MTP transfer, debug mode, etc) when I plug it into several different computers.

Thanks for your reply- I uninstalled all the drivers and still nothing when I plug the phone in, after a reboot.

I don't even get the USB menu (Charging, MTP transfer, debug mode, etc) when I plug it into several different computers.

It may be too obvious but did you try another USB cable? If it's not the cable try this with the default dialer *#*#2846579#*#* then select in background>usb hisuite, connect the cable and see what happens.

I have tried different cables but no suggestion is too obvious! My sister in law actually also has an Honor 8 and her cable on my laptop is recognized, so that's what I've been using to troubleshoot with my phone. I did go into that menu you suggested and I tried toggling HiSuite, Manufacture, and Google and exit the menu and still nothing when I connect the cable (other than charging). Thanks

Have you played with any of the developer options like USB Debugging or USB configuration...... Nevermind, just re-read your original post. I was almost sure the dialer thing would fix it but if a reset won't I'm at a loss. I still don't think that it's a hardware problem but I guess it could be. There are things like wiping the cache partition that I see some folks have used for various problems. That would be an option that wouldn't affect your apps.

[Q] Trouble connecting Nexus 5 to new laptop in MTP mode

Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.
Attempting to copy a 12MB file to it gives an estimated time of over 2 hours.
Scenario C. Success?
After tinkering with it for some time to no avail, I was beginning to worry if I have gotten a defective hardware.
Then I remembered I had an old laptop stashed somewhere, so I tried connecting my Nexus 5 to that.
And... voila! It works without a hitch (MTP mode, USB debugging off).
A maybe useful note is that I have used both the old and new laptops to transfer files to my Note before.
4. Possible causes
While many seems to have solved the issue by simply unplugging and letting Windows reinstall the drivers, I have no such luck.
I sincerely hope that it is not due to any hardware defects since
a) my Note can talk to my new laptop through the same micro USB with no problems, and
b) my Nexus 5 can talk to my old laptop.
I feel that this is a driver-related issue but I am not sure.
Is it possible that there are compatibility issues with using USB 3.0 port (which should be backward compatible...) or a 64-bit Win 8 Pro?
Any help is appreciated!
It is so strange..
I just bought a USB 2.0 hub and connected my phone to my new laptop through it.
Guess what... it works perfectly!
Apparently my problem was that my new laptop only had USB 3.0 ports for me to test on?
Doesn't make sense... thought 3.0 is backward compatible and my old Note works on it!
Maybe I'm missing something but I'm happy it is solved for me now
This solution worked for me. Go to http://forum.xda-developers.com/showthread.php?t=2512549 and see post #5. Be sure to thank n7of9 for the link and WugFresh for his toolkit solution. Enjoy.
Hey,
I basically seem to have the same problem as you do.
My laptop also only has USB 3.0 ports and Windows 8.1 Pro 64-bit installed.
The Nexus 5 doesn't get installed, in MTP mode it is just shown with the yellow exclamation mark in Device Manager. Downloading different USB drivers including Google's and trying to manually install it doesn't work at all. I specifically checked that all older similar drivers are gone, so I doubt that older Android devices could be interfering.
On the other hand, as you noted, using an older computer with USB 2.0 works perfectly, I had the same result.
To be honest, I'm not much of a developer or Android tinkerer, so I'm not really making any progreess... In the end, I think I will follow your example and test it with a USB 2.0 adapter.
Did you manage to get it to work without this workaround?
Kind regards! :fingers-crossed:
I'm using Linux Mint. Just plug the Nexus in. It shows up as a folder. No hassle

I had a lot of issues with my S3 and my work computer (windows XP SP3) and it was because I had half installed some USB driver that windows tried installing.
I fixed the problem in device manager by manually uninstalling EVERY SINGLE USB DEVICE attached to the computer while I had my phone plugged in.
Word of caution: You'll probably uninstall your mouse/keyboard doing this.
Once everything was uninstalled I reinstalled the Samsung drivers and it worked fine.
The same computer only required me to install the Google drivers for my N5. If I enable USB debugging, I all of a sudden can't install MTP drivers, but USB debugging disabled works fine.
USB & MTP mode
I have the same problem with my Nexus 5. The only workaround to transfer files to my phone from a computer via USB cable is to enable USB debuging, set the phone to PTP mode instead of MTP and then it shows in My Computer as a camera. I can only access the DCIM and Pictures folders but for now I have to settle for this...I copy all the files I need to let's say Pictures and then using a file explorer (on the phone) I cut and paste them to the folders I wish...e.g. movies to Movies, music to Music and so on...
I had same problem. Developer Mode...USB Debugging ON worked.
I have this problem too, but I got it to work using a galaxy s3 cable. for some reasons the cable that came with N5 did not work.
Its usually just missing drivers.. You can get them straight from Google or a toolkit as mentioned! (P.s you need to download a little applet like thing from Google if you want to hook up your Mac to your n5)
See andoid.com/filetransfer for the drivers.
This worked for me when all else failed: http://forum.xda-developers.com/showpost.php?p=35854664&postcount=7
Hope that helps!
The problem I am having now connecting is that my phone got wet recently. I dried it immediately and used dessicant to withrow the water and now it works (sort of). Now when I plug my phone into my pc, the usb debugging icon doesn't even show up.
I tried connecting to both my work pc and home laptop and they both say the same thing, that the usb device has malfunstioned and that windows doesn't recognize it.
Is it time for a new phone?

Sounds like the usb is shorting. How long did you let it dry. Give it more time and try it again.

Yeah maybe thats what happened. It's been drying now for about a week. The screen was the major problem at first but has since dried there mostly.
Hopefully it will come back. Would suck to have to buy a new phone because of that.

MTP connecting problem solved
Going back to the subject of the thread: I am pretty sure that ADB drivers and SDK (I am confident that a lot of nexus users have their devices rooted and that means they must have the above installed) is what is causing some sort of conflict when trying to connect the Nexus 5 as MTP. After I reinstalled the windows (W8) on my computer and connected my Nexus 5 it took @1-2 minutes to auto install the drivers and then worked fine...I have no ideea what happens if I install ADB and SDK again...

If you tell the SDK not to install the drivers it'll be fine
The simplest and shortest way to connect google nexus5 with PC as MTP(Media device)
When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
Unplug the device from the computer
Go to Settings -> Storage.
In the ActionBar, click the option menu and choose "USB computer connection".
Then select Media device(MTP) or Camera(PTP) based on your requirement...
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection..
I hope this will help!

Hello !!!
I faced the same problem with mine...
Couldn't connect my phone with my laptop.
It installs the driver but not displaying the folder in my computer.
I uninstalled the Existing samsung driver in control panel.
Then the issue has been solved,
Or uninstall previous mobile's drivers
Try this!?!
Search for Universal Driver here in XDA. Had the same problem most of you are having. First try and BAM! Works like a champ...
NEXUS 5
Problem solved for me
I have no more issues what-so-ever after I unninstalled ADB & SKD drivers...Windows(8) installed my phone by itself after a restart and it works as it should in MTP mode and PTP mode.

[Q] Nexus 5 not connecting to computer (usb), does not show in device manager

Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.
Have you tried enabling and disabling usb debugging while plugged in?

Are you sure you're using a data usb cable and the usb port is good?
Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.
so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance

PC connection

Hello all. I have a problem that is not unique, but I cannot for the life of me seem to fix it.
My S6 will not stay connected to my PC so I can transfer files, use Kies, SmartSwitch, or anything. Sometimes I hear the Windows notification that it's plugged in, but even when I do, it goes back and forth between being recognized and not. Most of the time it doesn't even show up in Device Manager.
I'm currently running Windows 10, but it did the same thing on Windows 8.1.
I have downloaded the Samsung USB drivers as well as allowed Kies and SmartSwitch to install them.
Thinking my Windows 10 being upgraded from 8.1 without a full wipe carried over whatever problem was in 8.1, I did a full wipe of my PC and reloaded Windows 10 clean. That also didn't help. Note: when I first installed Windows 10 clean, my PC didn't recognize my phone at all. It just acted like a charger. After I installed the Samsung USB drivers, it started making the 'connecting' and 'disconnecting' sounds. Also, the most I got Windows to recognize my phone was for about 5 seconds, and that was right after turning off USB debugging. But with it on or off, it still won't stay connected.
And yes, I've made sure (when the phone has connected for a second or two) that it was on MTP. But... I've tried the camera mode as well.
This makes it not only impossible to move files easily between my phone and PC, but also to use Odin.
I've read many posts where people have this problem, but everyone just tells them to go download the Samsung USB driver, and after having done so three different ways, I can say it doesn't work for me.
Anyone who could solve this for me... well... I'd be willing to donate a bit of money to the cause of your choosing, including yourself.
No one else has experienced this or is willing to shed some light on this?
When I had that issue with my nexus 7 I switched out the USB cable for a different one. Seems to have improved.

Try downgrading to windows 7. Before you connect your phone to the computer install necessary drivers, samsung driver and kies. Use USB 3.0.

Yeah, I'm definitely not going to downgrade to Win7. That would be 2 Windows versions ago for me. I've installed every driver available, from Samsung's (with and without Kies) to Google's universal Android USB drivers, and none have worked. I've also tried USB 3.0 and 2.0 ports (I have both on my laptop).

Hey, did you try connecting other usb devices to your pc to see if they connect? furthermore, you should also try to connect your phone to another pc to check if there is a USB port problem with your PC/Phone
For me the standard USB cable gives this problem, with another cable it works perfectly. So try another cable

Hi, everybody.
May you help me, please? My S6 SM-G920F, also is not recognised by windows 7. Smart Switch say S6 dont connect in emergency mode. I supose they means "emergency calls only", is that? I had bought the phone locked to O2 but I live in Portugal and I have no valid O2 SIM card. I bought an unlock SRS by TomMobile because I dont knew that needs a USB cable connection. What can I do, please?
Thanks in advance. AS

Hello all. I have a problem that is not unique, but I cannot for the life of me seem to fix it.
My S6 will not stay connected to my PC so I can transfer files, use Kies, SmartSwitch, or anything. Sometimes I hear the Windows notification that it's plugged in, but even when I do, it goes back and forth between being recognized and not. Most of the time it doesn't even show up in Device Manager.
I'm currently running Windows 10, but it did the same thing on Windows 8.1.
I have downloaded the Samsung USB drivers as well as allowed Kies and SmartSwitch to install them.
Thinking my Windows 10 being upgraded from 8.1 without a full wipe carried over whatever problem was in 8.1, I did a full wipe of my PC and reloaded Windows 10 clean. That also didn't help. Note: when I first installed Windows 10 clean, my PC didn't recognize my phone at all. It just acted like a charger. After I installed the Samsung USB drivers, it started making the 'connecting' and 'disconnecting' sounds. Also, the most I got Windows to recognize my phone was for about 5 seconds, and that was right after turning off USB debugging. But with it on or off, it still won't stay connected.
And yes, I've made sure (when the phone has connected for a second or two) that it was on MTP. But... I've tried the camera mode as well.
This makes it not only impossible to move files easily between my phone and PC, but also to use Odin.
I've read many posts where people have this problem, but everyone just tells them to go download the Samsung USB driver, and after having done so three different ways, I can say it doesn't work for me.
Anyone who could solve this for me... well... I'd be willing to donate a bit of money to the cause of your choosing, including yourself.

iphone and Samsung S6 same issues
Hello wvcadle,
I have the same issue and it is quite frustrating. Did you find a solution? As some additional info for you. My i-phone was doing the same thing on my computer. I thought it was the phone and I upgraded to a Samsung S6. It does the same thing as the I-phone, what you described and it works fine with other PCs. SO must be computer related. My bet is windows and my IT recommend a full wipe and reinstall of windows. We run Windows 7 Professional.

Most of the basics have been covered. Did you ever try different cables? Or on another computer? Do you have any issue charging the device by cable?

Most USB ports only put out about .4 - .5 amps. They will generally charge more slowly

its not usb port or cable problem... this problem starts when someone trying to root ... & damage efs partition..
Its just Cable problem my friend.
Find and buy a reliable usb cable. You stated all options and fixes but you never been able to speak of your cable
For those whose saying that root and damaged efs will affect your phone connection to your pc, he's wrong . Rooting and corrupted efs partition doesnt have to do with windows driver etc.
Just think out of the box.
If it did not work with your pc. Then switch to other pc with smart switch & samsung usb driver installed.
I prefer installing samsung usb driver and then smart switch.
If it didnt work, try using different cables.
If it didnt work again, use other samsung phone and see if it connects.
And so on ...
Having exactly the same issue...
Started just today (yesterday and previously no problems experienced, phone would just connect & be visible and available for data tfr, no problems). Today, no go. To be clear, it's Galaxy S6 128 gb running Lollipop, which no longer connects for data tfr via USB to laptop running win7 ultimate. It only connects and charges. I have checked for updates for both windows and Android. There are none outstanding. I have downloaded & reinstalled samsung USB drivers on laptop. No change. I have tried 4 different USB cables, 2 new, and the cable supplied with phone. No go. I have tried these cables in all USB ports on laptop. I have tested other devices in all USB ports and connectivity to laptop with other devices is fine. I have tried connecting phone to another PC, same issue (only charging). I have done the developer thing and switched USB debugging on, no change, and off again, rebooted both devices multiple times, all with no change. Yesterday all was good, today - nada. Anyone got any other suggestions?? Wit's end, reached.
It's been said many times already, but I had this problem and it was the original white cord that came with the phone. It would not stay connected to my laptop nor would it stay connected to the charger. It sat there blinking and making the charge cord inserted sound when plugged into the charger/computer. I changed cables and it went away.
I remember picking the phone up one night in bed and forgot the charging cord was attached. I reached the end of the line and it yanked out of my hand and fell to the ground. This is the only thing I can think of that damaged the cord. I was lucky it didn't damage the charge port on the phone. So you could have a screwed up charge port on the phone if you've tried new cords with no avail. I wouldn't encourage it but sometimes the charging fin can be bent back into place to make a better connection....had to do this on a dell tablet.
Also, if you're using lock screen or fingerprint, I believe you have to unlock the phone after connecting to PC to access and transfer stuffs - just a thought.

Thanks for the input - it's not a lock screen issue - I've tried connecting with screen locked (then unlocking when connected) - and connecting with screen unlocked, and I don't use the fingerprint security option. No changes observed. I have had concerns about the charging fin, but I am always careful connecting and careful with the phone generally - it looks OK and I'm rather loath to start bending it about in case I just f**k it up entirely. At least it still charges OK. Looks like I might have to bite the bullet, wipe it and take it to a Samsung repair centre. At least it's still under first year warranty. Thanks for your time talroot.
Original white cable did not work from day 1. Fast Charging is working fine but USB connection and tethering is a hell. You need a new cable and a good quality, not some cheep stuff.
Samsung really disappointed me because I owned many of their devices and most of them had some small issues, but after this in s6 edge and overheating issue (especially when using Gear VR) I will not by from Samsung anymore.
just for the record....
...my phone started connecting to laptop again. After about 3 weeks of non-connectivity, I connected again to charge and *ding* it was an external USB device once more. Same cable as before. Doesn't make any sense, but there it is. Thank you everyone for your input.

USB Problems

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

Obvious Question #1: Did you check the phone notification dropdown area to verify the phone is in MTP or PTP mode so it will show up on the pc? As for transfering files...you do have the option of loading up a microsd card with whatever files or installing a wifi adb app to connect wirelessly. You could even use an app like airdroid to let you do all sorts of things.

Therre's no notification after connecting the usb, it just charges the phone, seriously, I've tried everything to enable MTP but nothing does the job. And what do you mean by using an adb app? Can I root my smartphone by a wireless connection?

You are overcomplicating things. 1st...there is ALWAYS a notification in the dropdown that says what mode the phone is in....mtp, ptp, charge only or "cdrom mode" which installs the usb drivers. Pressing on that notification allows you to change the mode the device is in.
As for rooting....all you need to do that is to flash or boot TWRP (details on booting it are in the system image thread) and then flash the supersu zip from inside twrp to your device...reboot and done...but I think in the newer TWRP's they even offer options to root automatically...ie the zip is already built in. After rebooting to your phone you install the supersu apk from google play so you can configure what apps have superuser access.

I'm telling you, everytime i try to connect my smartphone to the pc nothing shows up, i only notice the device is charging, there's no option anywhere to change it to MTP or Camera or CD ROM... And I've tried 2 different pc's

Your telling me when the phone is plugged into the pc you don't see the notifications below or some version of them at all? If so then you need to fully uninstall the devices in device manager including remove the drivers...then use the drivers in the system image thread (since you obviously can't use the ones from "cd rom mode" which would be the best solution). USB debugging isn't even an issue yet...your phone should still show up to the pc as a camera device (ptp) under just about ANY scenario using even built in windows drivers.

Thanks for all those tips, but I already tried that out aswell, 2 times to be precise, deleted all the drivers, rebooted pc and smartphone, tried different cables, but still nothing ever occurs.

Have you tried a different cable? Perhaps that one is damaged or is only setup for charging? Only thing I can think of.
And then I realize you mentioned that Not sure what else would prevent it from giving you those options.
I'm also facing similar issue after the 2 update. Were you able to fix this?

Which kind of USB cable(s) have you tried specifically? Were they cheap eBay/generic kinds or well known branded ones?
Something as little as a Micro USB cable can cure a lot of problems. It needs to be a well built one by a known manufacturer to avoid problems.

Actually I've been having pretty good luck with the $1 ones from Dollar Tree but the key is certainly to try multiple cables....on some the microusb plug will make it difficult to get a solid connection especially if you have a case on the phone.
You may be missing the point of "trying" different cables. It's not so much the "quality" of the cable, it's the fact that some cables are for "power only", and "will not" transfer data, regardless of how hard you try.
You need to be using a "proven" data/power cable, otherwise your beating your head against the table for nothing.
Just to add, I put a piece of red tape on all my usb cables that are power only, no guess work.
I own idol3/moto g 2015 and s3, have no problem with other 2 device. I'm having this MTP issue after the UE40 update. Verified in all 3 OS, adb is detecting the device but not MTP/PTP. Idol3 support is not worthy responses.

Well, USB works fine here, and I've had 5 different rom's, 2 Canadian, 2 US, and the Chinese rom, on this phone without any USB issues, sorry, can't help any further.
After a complete wipe and restore, it worked.

I had the same problem as well. It only showed charging when I plugged in the USB cable. Tried switching cables, turning off and on USB debugging but nothing worked. I finally just rebooted the phone and then it worked again. Strange that it suddenly stopped.
I have a different issue; the different USB modes work fine but I don't have the 'cdrom' option in the USB mode dialog. I've tried various Alcatel ADB drivers that I have found and none are working, using Win7 64. My Idol 3 4.7 is 6039I (US).
Answered my own question, simply install the Mobile Upgrade Q software.
nope, doesn't show up. it's a bug. i had it before, googled until i found a fix and got it working, now it's back to not being recognized. nothing shows on drop down menu.

No USB Connection

Today, looking at the storage left i noticed i had only 12.55 instead of ~25 (my N5 is the 32gb model) and i tried to reset the device following a guide. Easy, right?
No.
The device didn't connect to usb, i tried 3 different cables, on 3 different pcs, with and without drivers, uninstalling and reinstalling them, even reinstalling windows on a machine. Nothing.
I thought it could be the OS, so i changed rom(i put on Cataclysm 6.0.1) but the situation was still the same.
I even tried to mount the storage in TWRP but no signal at all.
Not even fastboot. Only charge.
You are my only hope, please help me.
What guide did you follow? A factory reset is not called for yet.

here some suggestions on the usb ploblem, didn't work.
I also tried the driver guide from NexusRootToolkit, resulting in a 30 second connection recognized by the phone but not by the PC, a laptop running Win8.1.
i didn't include 3 other threads on XDA that redirected everyone to a common troubleshooting.
While plugged in, swipe down from the top and change usb charging to usb for file transfer.
Is that what you are wanting?

There is no signal AT ALL, no choice between charge and MTP, no devices in Device Manager on windows, nothing.
I tried turning on debug usb, no signal.
Tried forcing MTP in developer settings, nothing.
Only one single time i heard the classic windows sound telling me a device was plugged in but there was no phone on file explorer and the phone was only charging.
It's only charging now.
UPDATE: turns out the FLEX connector is the real problem since the screen went full retard and now looks like this http://forum.xda-developers.com/google-nexus-5/help/nexus-5-screen-colorful-static-t2600032
