Hello everyone,
first sorry for my english.
I have Nexus 2012 with 3G modem. I had android 5.1.1 witch root and twrp, but was slowly and i made wipe. Then system doesn't work. I decide to install again 5.1.1 via nexus tool kit - tablet work. I connected rtl sdr dongle install sdr scanner - it's working. Reboot tablet and it doesn't work. So i tryed to install android 4.4.4 - and i have the same situation (of course have root) first install and sdr is working, reboot and it doesn't work. I have info " no connected device". Before i made wipe and tablet work slow everything worked fine. I use active hub, connect directly to otg cable - the same problem.
I don't have any idea. Could you help me? Dongle sdr connected to computer work.
Regards

Hi!
Yestarday I installed VegaComb on my POV Tegra. The VegaComb 3.2 Build7 is fast and stable.
1. problem: the USB on my tablet works only in PC connection mode. When I plug in a pendrive, or external hard drive nothing happens. (looks like not connected...)
2. problem: I can't install Build8.1 because VegaModdedStock_v1.10_v2.exe writes: "unknown device".
Can anybody help me?
Ad 1: USB host is not supported yet in vegacomb (at least not in the standard USB connector)
Ad 2: I installed build 7 directly from the standard Point-of-View firmware 1.10, which ran fine after doing a factory reset. But than I wanted to move to build 8.1. From build 7, I was able to install modded stock v2 without problems, which gave me access to CWM. Than re-installed build 7 through CWM. Than installed the build 8.1 patch through CWM. That works on the Pointof View tablet too.

Thx, it works, but I wait for a newer version with working USB host...
Hi guys,
I have a massive problem.
I recently updated to 4.3 rooted etc, after a few days of not using my nexus 7 on the pc I wanted to flash a new rom.
Now my N7 is only shown as an "Unknown Device" in my Device Manager.
I tried to deinstall Drivers, install, everything, I tried every possibilty in Wug's toolkit, nothing worked. I also tried it on another Notebook where i have never connected any mobile device, same message and i'm not able to install the drivers.
I also tried several ports and cables(the original one included)
Here is the message:http://i.imgur.com/tgxOeZQ.jpg
Translation: The optimal driver software for your device is already installed.
After this I flashed back to 4.2.2 (downloaded the rom on my N7) while performing a normal factory reset, I can't wipe everything because then I am not able to flash anything.
So after flashing to 4.2.2 my N7 was shown as a portable device in my device-manager. I then turned on USB-Debugging to stock+unroot, it was then shown again as a Unknown device, in both modes, USB-Debugging turned Off and On.
So now my question, is there a solution to this? I searched for possibilites to get back to stock without USB but most of them were a bit sketchy or had dead links. Please help me (sorry for my bad english)
Edit:
I just the cable of my old Motorola Defy, and it randomly connects and disconnects(still shown as unknown), so basically I think it is possible that my USB plug is broken(it takes about 6 hours to load the battery which I think might be as well a reason for a broken USB plug).
But to send it back to Google I need to Stock Unroot first so here my problem is again!
greetings
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
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 am desperatley in need of a ROM for the 2012 Nexus that supports USB UTG and Charging.
I would be thankfull for every Info with a working Download-Link to a ROM.
Thanks!
I need it too. And I'd like to have undervolting feature. But looks like you should find ROM by yourself and then flash kernel with OTG+power
FWIW I flashed my 2012 N7 with LN14.1 build 20180625-UNOFFICIAL, OTG and charging work fine, however MTP connectivity to Win PC only works when the N7 is booted into TWRP recovery.
See https://forum.xda-developers.com/nexus-7/development/rom-lineageos-14-1-nexus-7-2012-t3530261 for download and installation info.
I am also looking for a way to use a music player from usb/powered usb hub/fat32 60G card in dash car mount.
