USB/MTP Problems - Samsung Galaxy Nexus

Ok so recently I picked up this head unit for my car. It is amazing, works great and sounds epic. One problem though, it will not work correctly when connected to my GSM Galaxy Nexus via USB. It works great if connected Bluetooth, but you lose a lot of sound quality that way. USB always sounds way better, however when I plug in my phone nothing happens at all except that my phone starts charging. I wonder if is the ROM I am using and if possibly a different ROM would solve the issue. I am using AndroidME. I am also wondering if the problem is that GNEX uses MTP. However several people have said that they use this head unit with a Galaxy Nexus so I don't know what to think. I am currently using a 16gb flash drive full of music and it's actually working fine. So I know the front USB port does work. Is there anyone who can tell me anything about this issue? And if it's an MTP thing is there a way to force a mass storage connection?

Do you use a custom kernel with fast-charge, or does your ROM have it built in with it's stock kernel?

Fast Charge is not on. I found out that the head unit simply does not accept MTP connections, thus anyone using ICS or JB cannot connect to it. Nothing to be done, I'm afraid :/

[Q] Galaxy nexus USB data stopped working (still charges)

My Nexus is stock but it is unlocked.
I have the latest CWM on there (touch 5.8.0.2)
I was currently downloading all the necessary stuff to flash to AOKP but havent even got there yet because all of the sudden my USB isn't working.
I have tried two different cables, the stock one and a different one (both which were working before).
I get charging working through USB but no file transfer.
I just did a wipe data/factory reset and wipe cache via Recovery, and still nada.
Am I cooked here? B-stock with no warranty from Expansys, now currently kicking myself for not buying brand new.
[edit] yes MTP and USB Debug were/are both checked on
[edit2] a lot of my searches seem to indicate that you can move and transfer via adb in recovery or fastboot while having this error. I am not finding that to be the case.
[edit3] windows 7 does not show any indication of a usb drive or anything plugged in as it used to before. This is obviously making it hard for me to try things like reinstalling drivers and whatnot.
thanks
It probably has nothing to do with the USB port...
Plug your phone into your computer, and then scroll the status bar down. You should see a notification "Connected as xx" Select that, then make sure connect as MTP is checked, if it's connected via ptp (camera) it won't allow you to sync files, for what reason so ever...
If that doesn't help, then reflash stock ROM, that usually helps.. With most problems anyway...
If both of these don't work, then I'm sorry, but I can't help you. I'd then call Samsung, and send it in...

Yea MTP was already checked on. USB debugging being on would have auto kicked in as well.
I flashed AOKP but still the same issues. The hardware might have gotten bonked - I hate how fragile these tiny little ports are!
Is there some kind of diagnostic I can run to see if it is truly a hardware issue?
It's the kernel, try another one

Just swapped to Faux kernel... still persists.
I'm really starting to think its the hardware but crossing my fingers there's a fix.
the same thing is happening to me, it started yesterday too!
I am on AOKP b-23, Faux kernel....
plug in my usb, it can charge but absolutely nothing happens on the computer side, try it on number of computers too... but the phone is able to charge.

Mine started doing this. Would charge‚ but sometime I couldn't transfer data or use adb. It seems that the USB didn't like to stay in my computer. Any little movement would unplug it just enough to keep it charging but nothing else.

I've since tested the MHL cable and also tried using the usb host cable to connect a mouse and both work... does that mean my data connection theoretically could be fine?
I'm using AOKP #23 with Trinity and not had this issue at all. Whether it's because I combine the ROM, Gapps and kernel before flashing I don't know but my phone is running fine
im having this problem as well. does anyone have a solution?
So all you guys that are having problems have enabled MTP through Settings >Storage?

Had this same issue yesterday ( phone was 1 day old ) had it plugged into my windows 7 machine and all of sudden the machine couldnt see it. So I wiggled the cable sure enough the computer saw it, jiggled it again and it would lose connection to the PC. Tried this on several PCs with Several cables and same result everytime. If I held the cable connected to the phone at the right angle it would never lose connection.
Ran to Verizon and the numbskull behind counter tried telling me that is normal and I would just have live with it, almost punched him in the throat. Demaded he go get another phone and show me if that one does it. It didnt so he swapped it and was to hasty about it, ended up giving me another cable charger and headphones WOOT WOOT
new phone doesnt do it as of this writing
See http://forum.xda-developers.com/showthread.php?t=1427539 This is probably the issue you guys are experiencing. Seems like you should swap it in or try to fix it yourself by changing the USB charging board.

i'm an android dev and this has happened to me. really really not good to no longer have adb access to my device. restarted both the phone and computer and tried a different coworker's computer and usb cable with no luck.
i used a samsung usb charger last night which i usually never do (i usually just charge it on the computer) and now this morning i have no data connection.
Hello,
have this problem already on my GNEX. After some reading, i got an idea to turn off Fast Charge in Trickster MOD.
And MTP now working .
Anyway there is an warning about fast charge - " Enabling this will disable access to phone storage" .
Problem solved
Yes, i can't connect mtp too and you rigth..usb fast charging is the problem.

Just so y'all know...Fast Charge is simply tricking your phone into thinking it's plugged into an AC outlet...rather than a USB port.
Thus MTP won't work.
same issue here
I'm having the same issue here. Charging works fine with 2 computers and multiple USB cables (as well as AC and car charger adapters), but data transfer has completely stopped working. My computer won't see my phone at all. I have the correct drivers (given that I used them to connect to my computer when I first rooted and unlocked the bootloader). Tried changing the drivers, but I can't get my phone to show up in Device Manager at all. MTP and USB Debugging are enabled.
The only thing I can think of is that I dropped my phone while it was connected, and now the USB cable only charges the phone if I bend it in a certain way (it usually requires upward pressure where the cable plugs into the phone to work). However, other USB charging cables work just fine without any pressure. Is there any chance that a new OEM Samsung USB cable might solve my problem? The other cables I've used weren't OEM.
I normally use a wi-fi data transfer app because the USB data transfer has been slow since day one, so that can be worked around. What IS a major problem for me is that I'm trying to re-root my phone after my root access was lost with the 4.0.4 OTA update. I didn't keep up with the news and only realized last week that my root access had been lost because I tried to do things that required root. Since the OTA update trashed my CWM recovery image, I seem to have no way to re-root and reinstall CWM aside from going back to my computer and doing what I did the first time. But if I can't connect to my computer, I can't do that. It also seems that I would need computer access to remove root in case I bring it back to Verizon for a replacement under warranty.
So on another note, if you guys know of a way to re-root my phone without connecting it to my PC, I'm all ears...

I have run into a lot of USB defects on the phones I have received. It might be wise to get Samsung to repair it, but you will be without a phone for a week. You could also try another cable.
I used to have similar issues except where the power got routed into the data port, frying my phone in multiple areas.
On Samsung's repair ticket they said REPLACED COMPONENT (I'm assuming this is the usb controller and port) this could be the solution but it requires sending it in.

[Q] Galaxy Nexus USB Connection Issues

I am having a very annoying issue with my Galaxy Nexus. When I connect it to my PC, it recognizes the device, however, constantly connects and disconnects. The USB cord is not moving. My other USB devices connect and stay connected (hard drives, mouse, printer, droid). I found this post attached, however, therre is no PhoneUtil code for the Galaxy Nexus.
Does anyone out there know how to solve this issue?

Have you tried another usb cable?
yes. same thing happened.
I have the same issue on 2 separate Galaxy Nexus phones now. no solution yet. I am on the phone with Samsung to see what they can do.
thanks for the reply. please keep me posted. i havent resolved my issue yet.
I've tried changing it from MTP to PTP and turning after switching between the two. I've tried two different roms, one based on 4.0.4 and 4.0.3. I've Tried several different USB cables, including the ones that came with my G2x and Nexus One. I've tried it in a USB 3.0 Port. I've tried using different kernals. Even when I get into recovery, windows still doesn't read somthing is attached. I've been transfering ROMS to it via dropbox. I don't think it's a rom issue as it should still show up in windows when in recovery. Also on those roms I made sure that they didn't have "USB Fast Charge" enabled, as I heard that can cause the issue I'm experience. Thinking it was an issue with CWM, I downgraded it, but still no USB. I'm stuck here. Any help is greatly appreciated.
The 1st posts pdf seems to be the most logical solution, we just need the phoneutil code for the galaxy nexus.
This seems to be a common issue with the GNex, see http://code.google.com/p/android/issues/detail?id=23789 and http://forum.xda-developers.com/showthread.php?t=1427539.
Please star/comment on the google issue tracker.
thanks for your post. the issue in the posts you included seem to be a different issue. those refer to the battery and charging icon, while my issue is related to the computer recognizing and connecting with the phone. i am going to post something on the google board though, i havent seen that one before. thanks!
It's the same issue...
Before I had the problem with the charging icon it started just like your problem...seems to be a problem with the usb plug....only solution is to send it to repair or exchange the phone.

What annoys me is that when I got the phone it was already rooted and I didn't have a chance to try it stock or back up the original. It was rooted with an older version, so I flashed 4.0.4 on it. Check out the reviews on newegg I'm not alone in reporting a messed with Galaxy Nexus.

I found a fix for the issue
This was a very frustrating issue for me. I just purchased the phone yesturday to have an issue like was unacceptable. After hours of frustration, I found a solution. First off, download the offical driver pack from samsungs website. Once you have the pack installed, plug the phone back in. Once you have completed this, go under development and enable USB debugging. After the debugging, you should have a stable USB connection and wired tethering will work. I hope this helps you guys with your issue. It resolved mine. This was also done running Windows 8 beta.

Connect to PC charge only

This may be a simple question but I can't find the answer so far.
Can anyone tell me how to connect my Gnexus to my PC using USB in charge only mode? i.e. so it doesn't mount as MTP or camera.
The only options available when you connect are through the notification bar option "connected as media device". Previous versions of Android allowed you to choose to connect for charging purposes only.
Thanks
so far i can´t think of no other way then using a charge-only cable (i know it sounds strange, but they really excist ). Since 4.0 the charge only mode provided in earlier android versions isn´t available anymore. except there is an app but i don´t know one.
If you are using a custom kernel that supports USB fast charge, enable it.

I'm on stock for the time being, about to flash the Franco kernel though. Not sure if that has fast charge, I'll check. Thanks.
You could always just ignore the warning popups on your PC. I charge mine at work with a USB cable and my PC does not have drivers so I ignore everything and it charges fine.

Try ever so carefully bending the usb port up towards the screen. Maybe with a tooth pich so you do not scratch anything. My SGS2 did this and after tweaking I had ZERO issues.
I just tried that it sometimes works now (rarely though ). I also noticed that the phone charges its just the MTP that isnt working
Same issue...
Went to root my Gsm gnex... Couldn't connect to the pc...
And now whenever I go into gallery it force closes... Could it be an issue with the internal storage?

Not sure I've had my phone rooted since the start of this year...I also reflashed a different ROM (full data wipe) so I don't think it's software related

Is there any chance that you've got fast-charge enabled (say if you're running a kernel that allows it and some script starts it upon boot?)? If so, then USB Storage or MTP isn't going to work and isn't supposed to until you do this:
1) take it out of fast-charge mode (like with .. trickster mod or an "#echo 0 > /sys/.. {wherever it goes, have to google it},
2) unplug USB
3) plug it back in
4) hopefully it'll work if that was the problem.
Just a thought and it's happened to me. I use a script I wrote on boot to enable fast USB charge and another from userspace to disable fast charge so I can see the drive.
Good luck.

I use Trinity Kernel and I made sure fast charge is disabled. I even flashed from Rasbean to CM10 to make sure it isnt related to the Rom or kernel. I'm guessing it might have something to do with the usb port in the phone as sometimes it connects but disconnects after a while
Thanks anyways

Ah well, too bad. I guess if you need to get to your PC and don't mind reduced speeds, you could always use a cifs (common internet file system) aware kernel, (faux or air I think, maybe more), then use cifsmanager to mount whatever PC share you like and transfer over the air for now.

hardware issue?
I did some research and came to conclusion that it is most likely a hardware issue. I had tried bending the pin inside the USB port but that didn't do the trick for me and seems to be a rather unreliable solution. I found a guide to replace the port yourself on ifixit. Since I don't own the tools and am not very good in repairing those things myself I had mobiletechvideos do it for me (i'm not allowed to post a link but you'll find it by googling for it).
It's a fair price for not having to do it myself and risking serious damage to the device. I got my phone back after 9 days and since then it has been working like a charm.
Anyway, it sucks that the micro usb port is that fragile and got damaged so easily in the first place.
I had connect problem and everyone kept saying i needed to install drivers and sending me to toolkits. I KNEW drivers installed. Turned out to be the usb inf file in sdk only had nexus one, ns4g, and the 7 wrote in. I copied the gnex info to the file and rebooted computer. Worked perfectly. Didn't even get the new hardware popup.
*Shaolin Shadowboxing*
I've been using trinity and noticed that sometimes it doesn't recognize the USB when plunged in after it's been up for awhile... Something happens when it's been on for awhile I don't know if it is fast charge related or not..
My solution... reboot the phone with the USB plugged in.. works EVERYTIME...

[Q] Why won't USB OTG work correctly? (Galaxy Note 2 N7100 x - demo version)

I have a demo Galaxy Note 2, which is running on the Revolution HD 8.0 rom. I flashed the following PIT file;
PIT_N7100_16GB_20121102.pit
The device works perfectly; very smooth, no FC's, the full 10.16GB of system space etc etc. However, one issue I am having is getting USB OTG to work.
When I plug in any one of my 4 USB OTG cables, I get the following;
'USB Mass storage connected'
'USB mass storage unexpectedly removed'
Does anyone have any ideas why this might be happening? I was hoping to use my Note 2 as a portable media viewer for the photos/videos I take on my DSLR. Kind of frustrating ...
Does your device do this at all? Better still, if you have a demo version of the Note 2, does USB OTG work on your device?
Really hope someone can help,
Thanks
There is a fix for that in custom roms try wanam rom 2.8.
I think you may find the flashable mod somewhere in GS2 forum.

USB OTG works on my device but...
Without a power source I can only see USB sticks and SDCards.
If my hard drive enclosures have an external power source that I hook them up to, then they work too. It the drive is NTFS formated then you have to use Paragon exFAT, NTFS & HFS+ to see it.
Thanks very much for taking the time to reply. I actually ordered and replaced the usb connection port, yet the issue still remains. So I am quite sure it isn't a hardware fault. I'll try and find the mod you have mentioned ...
Just out of curiosity, is there anything else I can flash beyond the pit file, the kernel and the rom? My device is a 'demo' Note 2, so I am starting to think that maybe Samsung put some other firmware file on the device that tells it not to fully mount USB OTG devices (it'd make sense to do such a thing in order to stop customers in a shop loading up their software from a USB stick).

I've tried everything I can think of to get this problem sorted. I am starting to think that it is a hardware issue relating to the fact that the 3G aerial that would normally be powered/connected to the USB connector board is not attached.
As such, the USB power being delivered to USB OTG devices is higher than normal (given that there is no 3G power drain)...so it perhaps overloads and disconnects connected devices.
I have replaced the USB connector board with a hardware revision 0.2 board (the one that came with the phone was a 0.7). I have installed the following files via Odin;
BOOTLOADER_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CODE_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CSC_XEF_N7100OXADLJ2_422394_REV00_user_low_ship.tar.md5
MODEM_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
t03g_0907.pit
I don't think there are any other software partitions on the phone that can be overwritten (the phone is therefore 'stock' as far as could possibly be the case with a demo phone).
If you do find a solution, I would be most grateful to hear about it. This is my perfect device for video/picture editing & uploading to Youtube whilst cycle touring (I don't need the phone connectivity when abroad). Although I can work around the USB OTG limitation, it would be incredibly useful to have that functionality.
All the best,
