Hi All,
I've been looking into the forum and came across couple of issue with 'dead' nexus 7 but none of them applies for mine. I was browsing the device, when suddenly it flashed and powered down. Now the table wont charge (there is no battery logo) and even the table wont powering on. I tried both with power and usb charging (for long hours).
The device is recognized by adb drivers (as unauthorized) hence could not do any modifications and not recognized at all by fastboot. I was wondering if someone had similar issue in the past with nexus 7 2013 (2nd gen) or similar android tablets/handsets.
I appreciate any help!
Thanks

How is it recognized in ADB or fastboot without powering on? My understanding is that the tab would not turn on if the battery is dead since it doesn't use the current supplied through USB directly. It could be something as simple as that; or the battery connector came off as it is rare one would go out abruptly like that.

It is recognized in ADB as an unauthorized and every command is type the response is "error: device unauthorized ...." Is there a way to Enable USB debugging from command line (windows/linux)? There are no blinking leds, and cannot boot it up into recovery mode.

I understand your saying "it won't power on" to mean nothing happens when you try to turn it on- as in it's totally dead. In that state, PC won't even see anything, let alone recognize an ADB device. You might want to backtrack a bit and tell what you did, what happened, and what you're trying to accomplish now, and maybe someone can help.
Does it turn on at all, and if it does, how far would it get?

Thank you for your reply.
After troubleshooting I noticed that its not dead since i am able to see the devices under adb devices. I also noticed that the device isnt dead because it rang when I clicked locate my device from my google account.
I think its the display which is faulty. I will buy an HDMI cable for the nexus 2013 device and connect it to hd tv to mirror the display.
Thanks

Hello everyone,
having major USB issues on my GNex. It's not charging anymore, but when the phone is off, it displays a charging animation. I could get it to charge once since this occurred, I left it plugged in overnight on my Mac (phone turned off). Did the same thing last night, no charge at all.
Mac OSX does not recognize the device, my Windows machine keeps telling me something like "the connected device is not working properly and can't be used... ". This message pops up every few seconds, so I guess it's constantly connecting and disconnecting. I can't access the internal storage on both systems.
My first guess was a hardware defect. But when I try to boot into recovery mode, a screen instantly pops up that shows Andy and displays a message: "Downloading. Do not turn off target.". In the upper left corner it displays " ODIN MODE" in small red letters.
When I press the power button in this screen (there is a big arrow pointing to the button with "start" written in it) the phone just normally reboots.
I can't get into fastboot mode because of this. I can get into CWM Recovery when i use the reboot into recovery option built in the ROM.
I dunno much about Odin (next to nothing). Has it something to do with Samsungs Kies? Could it be that something has put my phone in this "ODIN MODE" and it constantly tries to download something, making the USB port unusable? The port is not completely broken, as the phone displays a charging animation when it's turned off... so there is some connectivity left!
Thoughts coming up that this could be some kind of software issue. If there is a possibility to get out of the Odin Mode, it may solve the problem.
The phone is unlocked and rooted, running AOKP Milestone 5 and franco kernel.
I tried to restore an older nandroid, but it did not change anything.
Would send it in for exchange, but not able to relock the bootloader due to no fastboot access. If it can be confirmed that this is a hardware problem, I have to pay for the repair, I'm fine with that.
Has anybody any ideas that could be helpful? Any help is much appreciated, thank you in advance!
Do a search and you will find at least 30 helpful threads. Basically you only need to replace your USB charging board and it works again. Should be a warranty issue, but Samsung has really been an ass on handling this issue lately and claiming water damage.
I have mentioned it many times here: this problem can be probably solved by thoroughly cleaning your USB with soft toothbrush.
True, I also cleaned my port but it only fixed it temporarily.
Thanks guys. Tried to clean the port, nothing changed.
Ordered an OEM charging board off ebay, hope changing it will fix the issue.
Only thing I'm wondering about is, that the phone is stuck in Odin Mode when I boot it up with Vol. - and the Power Switch. So I downloaded Odin but it does not recognize the phone...
I am also facing the same problem. I am currently using the phone by charging the battery externally. Can someone confirm that changing the USB flex cable is the solution ?
Just posted in another thread but it is definitely the USB port for me. Using an HTC Vision (Google g2)
Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Ah yes, that is where it was hiding....But unfortunately the checkbox is checked.
This seems like a hardware issue, but I'm not certain since the phone still recharges when plugged in

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

Google galaxy nexus nfc battery. either the battery or the port is shot. People having issues.
And get your drivers from Samsung and Android sdk. Qbking77 has a YouTube video on how to set it up.

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?

I have a Samsung Galaxy Nexus. It is had some water damage in the past (making it near impossible to get repaired under warranty) and that has caused it to act funny. Funny = Powering off at random times and rebooting itself/causing the buttons to act silly. Recently it did the thing where it powered off and now it won't come back on. I know the power button still works and it is charging because when I plug it in the charging symbol pops up when I press the power button. However it won't power on. I plug it in to my laptop and it charges but my laptop does not recognize it is plugged in. Is there any sort of program I can download that will allow me to get into my phone or anything I can do? Also I have tried the Power and Volume buttons to try and power it into Bootloader mode but that does not work either. Neither does pulling the battery or putting a different battery in or using a different charger.
Isnt it clear it is dead? Electric stuff+water=death. (Physics 101)

So your galaxy nexus turned into a Nexus 4? Or is there another reason you're in this forum?
Rude
Why are you people so mean? I am looking for help, really just a program that would allow me to plug my dead phone into the computer (since it indicates it is charging) and allows me to get files off of it. That would be nice.

Hey man,
I'm not sure if your gnex is salvageable, but if when you plug it into your laptop it indicates charging perhaps you may be able to get to your data. First question...do you have usb debugging enabled in settings? We have to get your laptop to recognize the phone as a drive,then try to grab the files. Tell me more about what happens when you connect it. We aren't all mean, some here just forget how it was when they had nothing but questions and no answers. Most in the forums are very helpful, regardless of experience level.

Thanks for your civil post, I will try my best to inform you more on what my phone is doing.
When I plug it into the laptop it does indicate it is charging but that is the only sign of life I can get out of it. After reading a little bit more on the issue I figure might be the power button that is the issue since it is running JellyBean. One solution that I have tried that has yielded interesting results is plugging the phone into the laptop via USB without the battery in the phone. My computer then makes the "beeping" sound like it is connecting to it and then "beeps" again like it can't connect.
I can't post a link but if you google katzz ifixit then you can go to the website I went to that described the issue and gave the solution I just described. Katzz is the name of the user who posted the solution.
I'm pretty sure I have USB debugging enabled in the settings because before my phone stopped responding I plugged it into the computer a lot to transfer files.
Is there any sort of program that would allow me to turn on my phone from my computer even though I can't seem to get my computer to recognize my phone?
Hi everyone,
first off, I've spend days now trying to find a fix. If I've missed anything, I'm sorry, it wasn't for lack of trying.
Here's the situation: I have acquired an HTC One X earlier this year which has worked quite flawlessly. I went ahead and unlocked the bootloader and installed a custom recovery. However, since I handed the phone off to my not-so-techy sister I did not use a custom ROM, and after the HTC update failed with the custom recovery I reversed that as well. The device should now be stock everything with unlocked bootloader.
After a few months my sister encountered heavy problems, though. She described them as battery related (wouldn't turn on correctly) and eventually she moved to a new phone. Now I have gotten the device back and I am trying to fix it. After charging it I managed to have it boot once. However, I but it to the side and wanted it to load some more. Ever since then the screen doesn't come on. The charging LED seems to work fine (eventually switched from red to green, too, indicating that the device is fully charged) and the button backlight still works, too. Most significantly though, the device is recognized as MTP device in Windows: I can access all the data in the storage without problems.
I have read that there is an issue with the HTC One X and the display connector so eventually I went ahead and took the device apart. It's lying in front of me now in pieces, but I still couldn't get the screen to come alive. The obvious conclusion would be to buy a new screen but the device doesn't feel like it's worth the investment. Besides, I would like to know for sure that it's the screen before I do anything.
So I turn to you guys and ask if you have any idea how I could access the phone via my computer. I tried to boot it up in bootloader mode but due to the strange standby methods HTC is using and not seeing anything on the screen I haven't been able to do that yet: Whenever I connect my USB cable it's recognized as MTP device, not ADB. Debugging seems to be deactivated so that doesn't seem to be an option. Does anyone have any idea how I could get the phone to talk to my computer (i.e. get into the bootloader or ADB screencast for sure)? With my Galaxy S I could simply plug in this dummy micro USB and would be sure to end up in download mode.
Any help is appreciated!
tl;dr: HTC One X screen is dead but LEDs work, is recognized as MTP device. How to make it talk to the computer?
Thanks,
rien
Alright, sometimes just posting stuff like this helps already. I was now finally able to get the phone into fastboot (apparently) and it's reacting to the fastboot commands. I suppose the next step is to load CWM and connect via adb. This way I can at least do a factory reset.
Does anyone have any ideas regarding the original issue with the screen? Especially since it does seem to work occasionally. And doesn't show any fragments...
Can I enable USB debug mode from within the recovery to work in the system?
The touchscreen on my 2013N7 fizzled out earlier. Responsiveness has been on and off for the day - for a few hours it would improve after I press on a certain spot on the back of the device, but after that it has gone entirely. I've rebooted several times and there is no response.
I'm trying to use android control (http://forum.xda-developers.com/showthread.php?t=2786395) to just access it and get my data off of it, but when I plug it into a PC, the PC doesn't recognize that there is a device plugged in at all, even though it'll still charge the N7. It's completely missing from the device management list; adb shell can't find devices plugged in. I've looked around for possible fixes, but all of the ones mentioned require being able to access the tablet.
I'm at a bit of a loss here - is there a way to get the N7 to show up on the device list, or an alternate way to pull data off of it?

The spot corresponds to the plug (att) and now it is time to unlock, reseat the cable and relock it as all of the problems relate to poor contact of the cable.
Same issue here,I am inserting a usb otg and connecting mouse there and then rebooting. This is really a bad issue
