[Q] galaxy nexus troubleshooting help please

hi, i got this sgn from a friend with a broken screen, and ive now replaced the screen and the phone turns on and boots up no problem. but when i plug it in to my puter, it says usb device not recognized, one ot the usb devices attached.... as well in settings the wifi on/off toggle starts greyed out, if i go into the wifi setup, i can push the toggle and it says turning on wifi, but then after about 20 seconds or so, it just flicks the toggle back to off. bluetooth if i press the toggle, it instantly flicks back to off, and wont turn/stay on. and the last thing i have noticed that is not right, is when i try to go into the camera, it just f/c's and says gallery has has stopped, yet if i go into the gallery, it comes up. but f/c's if i try to access the camera.. i am thinking its probably a hardware issue, just was wondering if anyone might be able to give me any extra insight or suggestions, thanks in advance.
edit: oh, and the phone charges through the usb port, which i find weird that the puter wont recognize it...

yeah, ive got a usb jig to boot it into odin download mode, but i think i tried it but the computer still didnt recognize it, ill try it again and let you nkow what happens.. also, i have another working sgn here, and i switched out the boards, cause the usb port is not on the mainboard, it is connected by a flex ribbon (thinking it may be a faulty usb port) but either one generates the same results..

You dont need Odin. Just use fastboot and flash the latest Factory image. There are plenty of guides on how to do that. Good luck! If you cant get it to work just let me know.

okay i tried your advice, but the computer still fails to recognize the phone, i installed the drivers, cause the computer picks up the other sgn that i have here, i just unplugged the one thats fine, and plugged in the one i am trying to fix ant it doesnt do anything,...

Go to System Settings -> Storage -> 3 dots -> USB connection, and set MTP ON (V)
and if that doesn't work, try another DATA cable

tried setting mtp on, tried setting ptp on, tried setting debugging mode off and on, tried a different cable, still nothing..
something i did notice was that i have another sgn here and i went to the storage settings, and i was able to uncheck both mtp and ptp and my computer installed a new device "samsung something something" cant remember what the new device was tho..
oh and the bootloader is locked on the sgn im trying to fix and it is unlocked on the second sgn i have here...
could that have something to do with any of this?

This seems to work for most any device changing Android OS on their device
Disconnect your device from your PC/Laptop.
1
From your Device, disable USB Debugging found in Settings > Developer Options.
1
From your PC/Laptop go to Device Manager, click on View> Show Hidden Devices.
1
Double click Composite ADB Interface, click on Properties.
1
Click on the Driver tab and choose on Roll Back Driver. This will uninstall the problematic drivers.
Should 'Roll Back Driver' option be grayed out, click Uninstall.
1
In the confirmation pop up window, click the box marked "Delete the driver software for this device" and then click OK.
Repeat this step for all Composite ADB Interface' entries.
1
Shut down your PC/Laptop, then start again.
(IMPORTANT: Do not "Restart" from the shutdown menu, you must do a full shut down)
1
Once PC has fully rebooted, open device manager and keep it to the side.
1
Connect the device to your PC/Laptop. Your PC will recognize the device as a storage device.
1
From your device go back to Developer options and select USB Debugging.
1
Unplug the device, wait 15-20 seconds and reconnect. You should now see your device from you PC and Device Manager should now have a "Portable Devices" folder
1
Should 'Composite ADB Interface' show up again, repeat (4) and (5) to roll back the driver update.
Ƹ̵̡- It seems, using the universal driver is also a good suggestion. These can be downloaded here -Ʒ
LGUnitedMobileDriver Version 3.11
[URL="https://dl.dropboxusercontent.com/u/31151290/LGMobileDriver_WHQL_Ver_4.0.3.exe"]Newest version 4.03[/URL]​

try to reinstall your OS.
always works.

In my device manager there is no ACER.... When I connect my LG G3 (F400S) Android 4.4.2 version, nothing happens in the PC, nothing happens in the device manager (no refresh, no new drivers of LG or LGE), the phone just charges (nothing from the notifications as well). I have installed the LG drivers (latest from LG website), LG PC Suite, tried to connect from LG PC Suite, but the PC refuse to detect the phone. I tried with different USB cables, different USB ports and different PC with different windows (7, 8.1 and 10), absolutely nothing. More surprisingly, my friend has the LG G3 (D855) which he can connect and get detected by his laptop but mine does not in this laptop with his cable in the same USB port! I think the problem is with the phone itself even if it charges. Please HELP!!

@Mr Rus
Is this device new or did you purchase used?
Does the device charge? If so, how?
Has your LG G3 ever been connected to your PC/Laptop?
Do you hear any sound from your PC, when you connect the device via USB cable?

Hi,
1. The device was bought as used online. It said new on the website but by the look of it i know it is used (scratch at laser autofocus and screen not properly glued OR it is a defective one).
2. Yes it does charge with the charger. The one i got charged the phone 0 to 100 in 4 hours. So i use my tablet charger (5V, 2A) to charge the phone with another cable (about 2h and 15min from 0 to 100) as the cable which came with the phone also causes the slow charging. When connected to the PC the phone vibrates and charges. I can see the 'electric current' on the battery icon and on the lock screen I can see it says charging (%).
3. It is the first time i've connected the phone with my different PCs. First one i tried without the drivers installed then tried with driver and pc suite installed. In the second PC the driver was installed first then the phone was connected. No positive result.
4. No, no sound at all. But i remember that there was some android adb stuff in the device manager (maybe same to the ACER...), i uninstalled it without checking the box mentioned in your instructions unfortunately. Then i heard a sound when connecting the phone. And right after that another sound, in my taskbar it says unknown device and error (i forgot the error code). But nothing on my phone in the notifications, it just charges. Under USB controllers in my pc i could see Unknown usb composite device (something like that) with yellow exclamation mark. I googled and had this uninstalled. Since then no sound at all.
I cannot return the phone for exchange as the shipping cost would be too much for me to afford (about USD 70-90). I am waiting for a software update as maybe this will solve the problems. I am still with kit kat 4.4.2. But if this is a hardware issue, it would be difficult to solve this.
Also the USB OTG does not work.

Maybe you have some problems with usb
Maybe you have some problems with usb port. I use usb hubs in such situations. Somehow, gadget seamlessly connects to a PC via the the extraneous device. I found good reviews for usb hubs on topchoice.best, if you suddenly decide to take my advice.

There is no PC connection setting, no MTP settings as well.

I am on a stock based rom.
If you are using aosp or cm based you might find the mtp in storage settings.
If the previous owner defaults the connection to charge only then windows will not detect the phone.
A friend of mine did the same and i found the setting to reset back to a mtp connection when plugged in with usb.
If i remember i had to hit the ellipsis button ... The three dots and it was in there. Sorry i am vague but it was a long time ago and i am stock based.
If somebody running aosp or cm can chime in and tell him where exactly that setting is that would be nice.
Otherwise goggle it.
Good luck my friend!

Unfortunately there is no such setting. I am using the stock ROM from LG itself (android 4.4.2) and the only setting about PC connectivity is Share & connect --> LG PC Suite. There is not options for MTP even after connecting the phone. I know for my friend when he connect his, he get the notification to change to charge only, MTP etc from the notification bar, but mine nothing. I done factory reset so, I do not think that the default setting is still set to charge only. Tried everything for this issue :/

For a last resort you can try another usb cable and/or a different usb port. There are also apps on the play store that will do wifi direct.

Thanks bro. Good job.

@TonyStark, thanks for the job you have done, for us, but my friend's AT&T LG G3 does not connect to PC at all, i have tried many ways like 3845#*850# Post Setting > Diag Settings > USB Set for Diag && Settings > Diag Settings > USB Set for Diag, but still no luck, i have also installed LGUnitedMobileDriver which was also suggested by you on the first post, No Luck yet,
Edited: In the last i came to know that the USB jack or port of the G3 was badly damaged, hence, after knowing that i told my friend that he is luck because his devices is still charging with this port condition. And he went to the hardware shop happily
And you were pleased to shut down that thread, I don't know why? may be you were trying or looking to make something better than that but we lost a good hope.
Now please help me what can i do with it, it is running 4.4.2, any thing we want to do with it is failed due to no USB connection to the PC,
by the way, i know i can root it with kingoroot and install autoRec and than TWRP and can upgrade to Lollipop by the way of putting all material into SDCard but does updating solves the USB connection problem OR we will be in the same state. As far as Marshmallow is also landing soon so, I think my friend must not stay on kitkat, and lastly an LG G3 like wooping device may not live its all life without USB connection. Please help. Thanks

how
you can use last version lg mobile driver

You can access the PC connection from your phone setting/storage/upper right corner option/USB PC Connection.
Then you will have 3 options of Charge tablet, Media sync (MTP), Send images (PTP)
Unfortunately even after I select MTP, my PC still can't detect my tablet LG G Pad 7.0 LTE

hi, thanks for sharing this info (new member here)

[SOLVED] Problem with USB/MTP and more

When i connect to PC it's "charging", pressing that "charging.." notification does nothing, long pressing displays "System UI". So i cant get MTP setting. Some guys say go to Settings - Storage - 3 dots <-------------- there are no 3 dots in top right. Problems started with me pressing "Revoke USB debugging authorizations". After that when i connect to PC i'm just Charging.
P.s : This is not only problem i have with this device. When i connect to LG bridge on pc (when i still could!) it would offer me constantly (even if i apply the update) 10b update, even tho i received 10c on OTA.
I cant access recovery options with power button combinations (i tried them all) and when i managed to get in recovery over ADB i was welcomed with android guy with RED triangle with exclamation mark.
In the end i'm seriously considering smashing this phone in desperation. This is my last LG for sure.
Only good experience i had with this phone is this forum. Full of people with knoweledge and willing to help. Thank you :good:

I deleted all drivers on computer, reconected, mtp started working fine.. Now to fix other issues..

This may sound like a long shot, clutching at straws (and perhaps it is), but I've had similar trouble when using damaged USB cables. Do you have any others you can try?
I don't have the 3 dots in storage either. You were probably reading tips for another phone/rom. I think you can only access the USB PC connection menu via the notification bar after you've plugged it in to a PC. There are also apps available that can access these "hidden" menus.

usb data not working after september update

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 ?

I am rooted with magisk and have had no issues until recently I cannot do any file transfers via USB. I also cannot use fastboot to Flash Android p. I want to unroot and remove magisk and Flash the latest OTA however I can't determine if I can remove magisk and unroot without being able to connect to fastboot. I'm also thinking that I may have to do an RMA. Any thoughts? Has anyone else had their USB data transfer stopped working. I've tried multiple cables, multiple computers and Chromebooks.

Same here, happened out of the blue last week. No Android Auto and no computer would see it. Still charged but no data. I reset it but no go. I RMA'd and new one is perfect. The thing I knew it was messed up for sure is when I got new phone and you use cable from old one to new one to transfer data and it would not see old phone.

We're you rooted on the device you sent back? I'm worried Google will not approve my return

I flashed the new update yesterday and afterwards I had this exact same issue. the reason why I discovered was I never got the prompt to allow usb debugging I had to enable and disable usb debugging several times while plugging it into the pc and after a few tries I got the message and was able to enable it and then I could use the phone on the pc

I had the same problem but I eventually got it to work again. Heres how:
1) Enable developer mode by going into Settings > System About Phone > Build number and tapping a few times (5 I think!)
2) Click back and then select Advanced > Developer Options
3) Scoll down the menu until you see "Default USB configuration". Tap and then select the option you require (ie: File Transfer)
4) Click back, then scroll up the menu till you see "USB Debugging". Enable USB Debugging.
5) Connect your Pixel 2 to you laptop/PC. The phone should appear in the Devices list in 'Control Panel\Hardware and Sound\Devices and Printers. Leave it connected for another 5 or 10 minutes and it should become available in "This PC"
6) Disconnect the Pixel2 from your laptop/PC
7) Disable "USB Debugging" and disable "Developer Mode" on the phone.
8) Reconnect the Pixel2 to your PC/Laptop. It should now appear under "This PC" every time you connect and you should now be able to view and transfer files between you PC and Pixel2.
Let us know if this worked for you.

Try cleaning up with a brush. I could be too much dust interfering with the connection.
I read on another thread that someone used post-it strips to do the cleaning.

To close the loop. Cleaning worked. Thank you.
