I updated my Nexus Player to MMB29U and rooted it using NRT 2.1.4. Now the USB port of the Nexus Player does not work after a full boot into Android. The only way that I can get the USB port to be recognized is by booting the NP into bootloader mode. In bootloader mode my Windows computer Device Manager recognizes the NP as an Android Device->Android Bootloader Interface. From this mode I have re-flashed MMB29U and I have also gone back to MMB29T and rebooted the NP, but once Android boots the USB port does not work. Before the update when I connected my USB Hub to the NP after it booted, the LED of the USB Hub would come on... now it doesn't. I suspect there's an issue with the NP USB driver not loading correctly. I have flashed in full wipe mode and have factory reset the NP several times. Any idea as to what might be causing this issue?
Fix it by going back to the factory installed image Android 5.0 LRX21V (full wipe) and then flashing 6.0.1 MMB229U (full wipe) and rooting. The issue with the USB hub might have been caused by flaky USB OTG cables. I have 3 OTG cables and only one of them works consistently with the NP.

Hi i have a nexus 7 (2012) everything was working fine until android 5. The device was slow and almost unusable. Then the 5.0.2 update came out and guess what? I updated it and now my laptop wont recognize the device so i tried a different cable and nothing. I plugged the nexus 7 in my second computer and nothing not even the sound that means you plugged something in the usb port. So i went to my brothers house and tried his computer.... the same... nothing. We plugged his nexus 7 (2012) 5.0.2 wich is the exact same device as mine and it works so we thought that it was the usb connector on the device and we switched my connector with his....NOTHING happens. computer wont recognize the device, no sound, no pop-up, no ADB detection. Does anyone have the same problem or a solution on how to downgrade 5.0.2 back to 4.4 without usb cable?
Thank you
Did you tried out to start n7 into fastboot mode and recovery mode?
Is usb not available also there?
fastboot and recovery mode also has no USB. absolutely nothing happens. when i connect the device it charges but the lightning icon does not appear on the battery in the status bar. and its not the usb port on the N7 i changed it.
?????????????????
Same here
I have the same Problem - a N7 GSM with 5.0.2 and no communication via USB.
I have tried different computers with Win7 and Ubuntu14.10. As well as differnt cables. (And all combinations of that work with my HTC M7, by the way)
Under Linux, not even lsusb shows the device, or dmesg shows any connection to a usb device.
To be completly honest, I did not give much love to my N7, I have been using it hardly. But when I did, I have been flashing some differnt Roms and testing different bootloaders so this might be some kind of my fault.
i updated to 5,1 and still the same problem so i assume its hardware related. but i know it is not the USB connector because i tried it on my brothers N7. and it works
Mine is quirky, comp recognizes it and can order boot but sideload and push to device don't work. Its odd.
Hello everyone I've got an issue with my Nexus 4 which is why I registered, as I simply don't know what to do anymore.
My Nexus 4 is not recognized via USB at all, there is no connection sound and ist does not appear in the device manager.
It is charging and does show USB charging if I tap the battery icon.
Things I tried:
Uninstall/Install Driver with and without WugFresh Toolkit (USBDeview)
different Pcs (different USB Ports)
different USB cables which all worked with other mobile devices such as Samsung S3/4/5 mini
checking and unchecking MTP,PTP and Usb debugging
fastbootmode
factory reset
replaced the USB flex cable as i figured it would be defect
I tried to root it with some of the apps available bur none of them work with LMY48T.
I think it might be firmware related but because I didn't flash a Custom Recovery the last time I rooted it I have no possibility to flash another rom.
The root access was lost when the last OTA Update arrived which is why I can't install a custom recovery via the clockworkmod Rom Manager.
The Pc I'm working with is running on Win 10 I'm running out of ideas.
Please help me, thank you
So I purchased a Nexus 10 off eBay with the issue of when it turns on it boots up to the android guy facing up with the red ! and says no command if I hit power button and tap volume up I can get into stock recovery. I tried wiping the cache no luck I have tried factory reset no luck. So I figure I would just flash the stock image via fastboot. But I can not get my PC to recognize the tablet at all no dings or anything when I plug it in. I have downloaded the drivers for the Nexus 10 from Samsung website. I have installed google drivers. I have installed Wug's Nexus Root Toolkit and downloaded the drivers from his toolkit with no luck. When in device manager and plug in the the N10 nothing pops up in device manager. So I figure well maybe its a bad USB port on the N10 but if I plug it into a charger when its turned off it will turn on. Also if I plug my OTG drive into the N10 while its on the no command screen my OTG drive will light up like its loading so then it can't be a bad USB port. I also have tried 2 different usb cables. Any thoughts or suggestions is appreciated.
So after getting around to installing the July security patch a couple days ago USB C charging stopped working on my Nexus 6P. If I use a USB A to USB C cable it will charge, but not if I use USB C to USB C. This persisted over multiple cable and chargers.
I tried to wipe the cache but had a problem getting into recovery - I could get to the boot loader but when i select Recovery i get a 'No Command' error screen. (eventually i found out i could power and volume up from this screen to get recovery, but the wipe cache didn't fix anything.)
Then I installed Oreo hoping that would take care of the issue but no luck. Any thoughts? Anybody else get this from the security patch?
Google support has not been particularly helpful.
Hi, i just started getting this issue today. I installed android O yesterday. My original charger which is C to C wont work but C to A will work fine. I've also had my 6p not recognized by my pc. It only charges when i plug it in. Tried different cables, different computers, but I think it might by my charging port. Google support tried, they didn't know what was going on.
But I'm stuck without a custom recovery right now and have lost root access. But phone is working fine. Messed up during flashing, didnt flash custom recovery thinking twrp would be intact but nope. And I cant use ADB to reflash anything cause my stupid 6p wont get recognized by my pc. haha

haha. use bootloader mode and fastboot flash the TWRP you overwrote when you flashed over recovery. ADB only works in Recovery, but fastboot works in bootloader mode which previously said you can access.
Hi all!,
For some reason my shield stopped working, it only boots in safe mode, but no other option in the fastboot seems to work. Tried to plug in the shield to pc with a usb c to usb a cable but it is not showing up in device manager so I can't flash it. It was on stock, nothing was modded before also. Is there anyway to fix the no device on pc? i've tried to different pc and 2 cables, my phone works with those cables, it is only the shield that doesn't connect using the farthest usb from the hdmi.
