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.

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.
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.
Hello. I finally got around to playing with my 2 ADT-1's. I was able to get TWRP and Pure Nexus TV ROM running on one using the dev cable and ADB. For some reason, my computer never detects the 2nd unit when I connect it. I've got debugging on and for fun I tried both dev cables and another computer. Nada. I fear that it may be a hw issue so I'm wondering if there is any other way I can get the ROM installed. I've tried ADB over the network (on both) but for whatever reason I can never connect. Could I get a cable and go USB port to USB port (bypass dev cable) or will ADB only detect using the dev cable? I'm all ears if anyone has any suggestions. I have not tried resetting factory defaults on it yet. Everything else on it is working fine. Thanks in advance.
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.
I try update my nvidia shield tv 2017 but now the System bootloop on Android circles animation (dont start box).
- I try fastboot with Controller but dont work (many, many times)
- I try conect to pc but dont connect device with fastboot
bricked bootloader??
I dont have solutions.... please help.
Sorry my english
Try un plugging the power then plug a USB keyboard in and hold the A and B key and then plug the power back in.
same problem for 3 days, can not enter fastboot mode. my shield is in bootloop
Shot in the dark, but have you tried different USB ports on the computer? I know in my case, some otherwise working ports will not work with the shield. Seems to be very fussy when it comes to which ports I choose. None of my front ports work on this desktop, I have to plug into rear ports in order for my computer and shield to see each other.
Also be sure to use the original cable that came with the shield.
Also make sure USB debugging is on.
Any fix ? Same problem
Have you tried "adb reboot bootloader" in command prompt when the android logo is looping?
I have no Android logo i have no os just twrp and twrp with no access adb and fastboot command dont work on NVIDIA logo
If you put lineage os on a usb stick can twrp read the usb stick? If so, you can install the zip file of lineage with gapps...once that's installed and booted up, you can enable usb debugging in the developers options and fastboot and adb should work again.
