I tried to upgrade my rom but the process crashed. The utility mtty doesn't work because when I connect the universal, boatloader mode by the cable, to the pc, it says "USB not recognized" (sometimes when I connect the computer is frozen till I disconnect the cable of the universal)
Please, I tried to have some solutions in the forum but all the posts indicates is needed previously the usb connection.
Do you know if should be possible to run the flash of the rom in other way, for example using a serial cable connected into the miniusb of the universal, because the boatloader screen says "Serie, v.1.01"
I apprecite what you can say please, I'm really in a hole.
Try this...
Try taking out the battery for a few minutes (10-30mins) and reboot your PC then repeat upgrade process. Hope that helps. Good luck!!!
I have the same problem on my PC at work, it's caused by a poor USB chipset in the PC, or trying to connect through a USB hub.
The only thing I found that worked was to try a different PC, then it was fine...

In my case it still happening in other computers. Conclussion: some piece of the software in the universal has been lost. The screen shows "Serial" that means on some way that is opened to comunication but not USB.
My questions are:
- should be possible to put some starting software in SD and do the universal boot on it.
- do you know how to connect to the computer COM! port from the usb miniport of the Universal.
I appreciate, I was not planning to replace now the Universal...

Now works.... I still thinking windows is so stupid software made for distroy our mind ....
Solved after install drivers for a converter usb -rs232 ( I was looking for the way to connect from rs232 the universal)
I'm happy again and I promise don't try to change rom again (at least for a while)
If some person is interested in what brand of software/hardware I installed, send me a mail...
Thanks hearing me ...

i have the same problem with my friend's uni
does it mean that you don't have to own any adapter, just have to install drivers for USB to RS232 adapter
if yes, where to find it?
thanx

I want to say that is running after doing some things and obviously some of it solved my problems. I made:
- unistall last version of activesync and go back to version 4.0
- delete all the applications using ports usb.
due the connection still not running (windows message: device not recognized) and because in the screen of universal I saw: "COMM1" I tried to connect from computer port rs232. By that I purchased some special cable, name: hama brand, rs232 serial, 9 pin - usb.
As you can imagine all the steps I followed were followed by the typical restart of windows. In this sense is important to say that the universal, after connect, need to do a soft reset each time (again windows....)
Other comment is that I unmark the option to connect by usb in activesync and mark the connection by com1.
and after all was done, connecting by usb the unniversal, kill wcescomm, windows said "NEw usb device, sync device". I started mtty and now appears the USB option, great! same time the screen in universal changed from comm1 to usb, more great....
and that's all.
does it mean you solve your problem using special USB 2 RS232 connector?
ZeD
PS: it was my first idea , but i still believe i can solve the problem using USB port

I think my english wording was not fine. I mean I solved my problem after install the sofware -drivers- of the rs232 connector, but connecting to the universal by usb as on standard way I was syncronizing previous the crack with activesync.
OK, where to get this driver?

I have had the same problem several times now (search the forum for the thread).
I tried three different PC's/laptops and three different USB cables all with the same error as yourself.
Eventually I got a connection but the laborious process of trying - failing, restarting windows and soft resetting the phone, trying - failing........... until it finally worked. I did nothing differently the time that it worked but the strange thing is that it has worked every time since! Maybe the USB driver the phone has a bug in it that causes it to get 'stuck' in a mode where it will no longer correctly operate but once you have managed to 'kick' it into action it seems toi then carry on working.
It was also a ROM upgrade that caused my USB phone driver to stop functioning. Maybe the fact that the phone has a slightly diffferent software configuration after the upgrade but exactly the same hardware fingerprint causes the driver to fail.
Every time that I have had this problem it is after an upgrade but once I have gotten it to work once with the new ROM, it always continues to function - until the next upgrade.

If you're stuck in bootloader mode only, visit www.buzzdev.netand look for ExitBootloader utility written by the great Buzz. Just follow his instructions or scroll thru' Universal's forum here and there for problems relating to "stuck in bootloader"
hope this helps
no device is not recognized by PC so any trying to use exitbl is not available, anyway this option was one of the first what i have tried
thanx anyway
ZeD
i had the same problem with the QTEK of my principal after I upgraded his ROMs.
(after the hard reset, the pocket remained in bootloader mode).
you can solve this problem in a very simple way:
you have to launch the bootloader installation (BL1.01_RUU_UNI_V.1.2.EXE) from the PC (still connected with the PPC through USB) while the PPC is in bootloader mode (on your display you see "USB > Serial 1.01" or something like that).
then you do a SOFT reset and the pocket boot normally.
very simple.
i hope to be helpful to someone.

I had some problem. After uninstall all usb applications in the pc and install the software for cable usb -rs 232, doing some softreset in the pda connected, it turned the screen message "Com" by "Usb"
Greetings!
Past couple of weeks when trying to connect my Arc to the PC it will not pick it up. It charges OK with the green light showing on the side but absolutely no indication from PC or laptop that a phone is connected.. I have 3 different cables and another laptop - having tried all the cables on both machines - still no joy.
No notification in the pull down - nada!
Reinstalled Win7 and factory reset phone half a dozen times - still nothing!
Running Win7 64bit but have never had issues with OS previously up until a few weeks ago!
Service provider was as useful as an ashtray on a motorbike!
Anyone know a solution?
Thanks

Thanks for the reply TheHaso. Should have mentioned I have tried with Companion installed and not installed, updater installed and not installed. With debug on & off, MTP on & off, MSC on & off, storage mounted/unmounted.
Really strange to be honest!
check your 'Device Manager' on your desktop,, it will show you if any hardware connected and not working propely.
right click and try update driver if show caution on portable devices.

Also tried this for a solution buddy.. Thought it was a USB driver had slipped off or something.
Truly baffled! If it's charging fine then why would pc companion not detect it :-S

I'm sure you must have already done that but may be try updating with a different driver and see if it could solve problem. I know because it also happened to me.

Uninstall the driver from device manager, then restart the pc and connect to another usb port

This will work...
I have almost the same problem on my ARC.
Download MyPhoneExplorer on your PC and install it.
Download MyPhoneExplorer Client from the market and install it on your phone.
Turn on USB debugging and connect your phone with your PC.
This works on my arc and i guess it will work on you phone as well..

Many thanks for the advice. Still not working and decided the final option of giving it to T-Mobile for repair.

USB cable only charges the phone when connected to computer. Tried the following
1. Using 2 different cables which previously worked for data but phone only shows charging.
2. Using pc and Mac and both does not see phone. Looked in device manager of windows but it nothing shows up. Both computer previously used for data transfer on this phone
3. Looking inside usb-c port but no lint or dirt. Although just before update to September security patch my phone has some water on the screen which I wiped off. And the phone does not show sign of problem other than no data transfer to computer
4. Factory reset phone and same thing
5. No notification shown for changing charging only to file transfer
6. Computer doesn't Bing when connected.
What else can I try? Anyone can help or confirm if their usb-c works after September update so I can narrow down to hard ware problem.
Anyone diagnosed this hardware problem before?
Do you have developer options enabled in settings? If you do go into networking/usb configuration and change that. If you don't you can enable it by going into about phone in settings and tapping the build number 7 times.

I tried changing the options to MTP, PTP, midi, charge only, etc but non of them make any difference to the computer, nothing pops up and does not show as new item connected in device manager
did you try changing from charging to mpt, and maybe back and forth, while the phone was connected to the pc? I have the same update on my 5x and mine is working fine.

Tried changing when USB connected and when not. Doesn't seem to make a difference.
I'm not sure what to tell you. You could try flashing the firmware package prior to the sept update. You'll have to re-set up your phone, but if you've already done a factory reset it won't be worse than that. That could tell you if it's software or hardware

I don't know how I can flash a previous firmware if I don't have USB access.. it's really frustrating. Looking from ifixit. It does not seem there is any chip near usb-c other than voltage control.
Can't seem to find how I can look at logs to know if USB has been engaged or if there is any error message. It's all dead end and my phone seem to be the unique case.
Are you rooted and do you have chainfire's flashfire?

I should have asked if USB was working before the sept update? I had a problem where the PC would recognize the device but couldn't run fastboot. This solved that problem but it sounds different than your issue

USB worked fine, I am using it for Android studio, and transfered music across as well. Looked at the post and it seemed that has to do with device manager. Problem is mine does not show up any changes to device manager. I.e . No ADB or other device. Seemed like no data is exchanged and windows treating it like a battery or something
Any fix for this?
I've hit the same issue and wondering if anybody has a fix for this yet?
I'm using linux and seeing no usb activity at all from my nexus 5x after sep 17 update.
I've tried multiple cables. Cleaned the usb port on the phone. Multiple PCs.
I've connected to the phone using adb over tcpip and seeing nothing in logcat except battery logs when the usb cable is plugged in and out.
Turned usb debugging off and on.
I've set usb mode in developer options to mtp (it was on 'charging') and restarted the phone. Then find the option is forced back to 'charging.'
Logcat entries during boot show no failures in regards to usb connectivity.
Charging works fine but no data connectivity via usb at all.
Anyone got any other ideas?
Hello world.
I had the same issue.
To solve the problem :
- unlock developer mode
- switch on debug usb
regards
J.
I had this problem too- did not have to enable USB debugging though, just enabling the developer options fixed it for me. Which is odd because I definitely had them enabled previously... I guess a recent update reset that and for some reason all the USB data options are tied to developer mode now.
I've got 790 (american, as i know). The same issue, no response from service, guarantee, doesn't help, pc shows it as unknown device. some other bugs, mobile data fails, no sim detected after a few seconds, violet camera with no focus, but nice when the distance ia ok, so matrix works ok, but no stabilisation.
Then, bad battery, it seems that the bank ia ok, but controller works bad. it charges enough time to think that the capacity is not degraded. I suppose that usb controller (pc connection and fsat discharging) are nearby problems.
None of the above posts worked for me on my N5x (8.1.0 March), but searched some more and found this to work for me:

Hello everyone. I'm just resurrecting this old thread so I can provide the solutions I have found to this problem. It appears this symptom has multiple causes, and there are different solutions depending on the cause. I have seen this problem twice now on my Nexus 5x (stock, no custom ROM) and solved it both times.
1. SOLUTION #1 - Messing with USB Configuration in Android
First time I encountered this problem, I did the following:
- USB Debugging was already enabled
- Enter USB Debugging menu
- Scroll down to "Select USB Configuration"
- Open this and select MTP, even if MTP was already selected. On my 5x, MTP was already selected, but selecting it again fixed whatever was broken, and the phone was immediately visible again in the Windows 10 interface when connected via USB.
2. SOLUTION #2 - ClockworldMod USB Driver was installed. Replace with Google driver
The second time I encountered this issue, the Solution #1 above did not work. Surprisingly, the adb devices command successfully detected the Nexus 5x. It's just that the phone wasn't showing up in the Windows 10 File Explorer interface.
The root cause of this problem was that I had installed the ClockWorldMod USB Driver because I was playing around with their Vysor App (on a different phone.)
BTW, I think the Vysor tool is really nifty for screen mirroring purposes!
To resolve the problem, I replaced the ClockWorldMod driver with the regular Google USB Driver.
(Sorry, XDA is not letting me post links because of my low post count. The link is:
h++ps://developer.android.com/studio/run/oem-usb.html )
The procedure is:
- Download the Google USB Driver from the link above and extract the ZIP.
- Enter the Windows Device manager
- Find 'Android ADB Composite Interface'
- Open the properties of 'Android ADB Composite Interface' and you will see it is from ClockWorldMod.
- Right click on this Interface and Select 'Update Driver'
- Click on 'Browse My Computer for Driver Software'
- Click on 'Let me pick from a list of available drivers on my computer'
- Click on 'Have Disk'
- Browse to the Google USB Driver you downloaded.
- Select that driver and load it on top of the ClockWorldMod driver. (Windows may claim that you've got the best driver already installed, but ignore that.)
After re-installing the Google driver, the Nexus 5x appeared immediately in the Windows 10 interface for file transfers.
Cheers, I hope this helps someone out!
I have the same problem with LineageOS 15.1, I am not sure since when, because I don't use USB that often, but I it must have been after the second update for 15.1. ADB and FASTBOOT don't work.
None of the suggested methods work. I am on Linux, but I also tested the USB driver solution on a windows PC.
The problem is, my phone does not trigger any response from the system I connect it to.
On Linux an lsusb/dmesg shows nothing, and on windows it doesn't make the classic "ding" when I connect something to the USB port.
It is like my phone isn't even there.
In the developer options under networking and USB, USB was set to charging only. I changed that to MTP, but it didn't help.
Now I can't change it back (not that I want to, but just saying). No matter what I press on this menu, it always stays on MTP.
I am here because of adb not connecting tho, MTP is not my concern anyways.
I am not sure what to do, format data, and wipe system etc. and go for a clean install? The problem is, when I boot into recovery, ADB and FASTBOOT don't work either, i.e. my computers don't see an USB connection. So will a wipe even help? I am scared I wipe my phone, and then I can't connect via ADB in TWRP.
Hello @ufopaper
Did you try to cleanup usb connector with a toothbrush and/or a soft plastic tool ?
Did you try different usb wire ? On multiple computers ?

Hi, I am needing some help. I connect my A5 to my laptop but a pop up from Win10 says that doesn't recognize the usb device. And continue saying that the last usb device connected didn't work correctly and windows didn't recognize it.
I think this happened after installing ADB and some other things like ZX3 to try to unlock my A5 and then uninstalled them, so perhaps I deleted some drivers in the process.
Can you suggest any solution for me to try?
Thanks in advance!!!!

Try connecting your device and then deleting its drivers in the device manager. After that reconnect it and it should show up as normal. Let me know if it helped
No, already tried that. Same message. Thanks!
I tried another usb port on my laptop, and recognize the phone. I don´t know we after some cel phone configurations I lost connection and recognition.
I tried again the first port and touch some items in the developers option, set the MTP protocol and now it seems working.
I stil don´t understand what I have to do to establish a good connection for every time I need it.
Regards.
Hi all. I'm back because I stll have the same problem. Can't connect A5 to laptop. The message says that there is a bad descriptor. It is the 43 error code from window 10. I tried downloading lastest Samsung drivers that comes in an .exe file and installed them. But same error.
Even trying to update the error driver to the lastest samsung usb driver, window says it already has the latest drivers and do not installed them.
Every suggestion from searching in google tried. Don't know what else can I do!!!!
Thanks for your suggestions!!!!!

I was using an old usb type-A cable with a usb type-a to type-c adapter. I tried using the original Samsung cable and it worked!!!!
I can believe this was the problem!!!
Hope I can help another with this! Thanks to all for your support!!!
Hi, I continue finding problems to connect A5 with Laptop. After finding the original problem was the cable, I now use always the original cable.
The problem is that the phone doesn't appear in windows explorer unless I go to developer options and set the USB configuration from RNDIS (Ethernet USB) to MTP (Media Transfer Protocol). After that, a pop-up appears asking for permission for data access. I have to agree with the pop up to see the phone in the laptop.
I think I have to change permissions to granted for ever the MTP. Am I right? Where do I have to set it?
Thanks in advance!!!!
New update!! I have just chat with Samsung. The told me to dial *#0808#. That access the USBSettings options. There I changed the default to MTP + ADB.
Now I no longer need to access the development options. It still appears the pop up, asking for permission, but for now I can live with that!!!
Hello! I have a mi A2 lite, I can't connect it to the computer using USB, it doesn't install drivers, it doesn't appear on installed devices. I've tried all the tutorials available on YouTube, but it doesn't work, does anyone know what I could do to fix this?
- I already downloaded the drivers and installed manually, but nothing changes.
- I've tried on multiple computers and none work
- When I bought the cell phone it connected, but after a while no more.
Does anyone know any solution to this problem?
Thanks!

Did you allow the phone to talk to USB. You must use the notification to enable file transfer or set the default in settings or enable debugging if you want it to show up to USB.

It does not appear the notification, but I have already tried to activate by the settings too, I already connected the debugging mode, but it also did not work. When connector it only loads, there is no other action.

Same here on v11.0.12. Its a driver issue. You need to install latest xiaomi drivers + qualcomm drivers. I fixed it before but it doesnt work again after i uninstall drivers.
I connected phone to PC with only old original short cable, no other cables worked :/
Have you tried to clean phone's USB socked? There are some spray contact cleaners, that can be used for this purpose.
