USB device not recognized - Nexus 7 (2013) Q&A

I used WugFresh's toolkit to unlock and root my Nexus 7. I also kept the stock recovery, so that I could receive OTA updates. So when I got the notification that an update was available, I downloaded it and tried to update my Nexus, but it would fail and show this message
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So then I plug my Nexus 7 to my computer, but my computer does not recognize it.
I've tried:
- switching from MTP to PTP and vice versa
- turning USB debugging on/off
- deleting relevant drivers using WugFresh's toolkit and then reinstalling drivers
- plugging in my Nexus 5, and then plugging in my Nexus 7
- doing a factory reset
It charges fine, and makes a sound when plugging/unplugging. It just always shows up as an unknown device. I've tried plugging into my desktop and my laptop, and neither recognizes the Nexus. I'm using the cable that came with my Nexus 7

you should of updated recovery and skip OTA, have you tried the normal way adb and fastboot?.
you boot into android os?,since the installation failed it shouldnt of overwritten the partition. i would use flashify and flash recovery and go from there.
sorry if not helpful, i never kept stock recovery, i only OTA on non rooted devices, i prefer downloading and flashing via CWM/TWRP

I'll give flashify a try. I just wanna keep as close to stock as possible. And yeah, I can boot it up, and it's useable. The computer won't recognize it, and I can't update OTA.

[Q] Not working drivers

Hey everybody.
At first I wanna say that i've flicked through some topics and none of them helped so I decided to get this thread.
I wanted to root my nexus 7, so I used wugu nexus root toolkit. Everything was done, device seems to be rooted etc. But I wanted to connect it to my pc and there's no response. I want the MTP mode back when there was a cute Nexus 7 icon at my computer. Okaay. So then I wanted to connect my Galaxy S running CM 10.1 (usb storage mode) aaaand no response ! The thing is that gt-i9000 is visible in devices

When I connect Nexus 7 it says that Android ADB interface is an older device and cannot be connected to usb 3.0. Alright, so I connected it to usb 2.0 and Nexus 7 shows up at the bottom of the devices in the unassigned devices,
I remember before I rooted the device and installed drivers from the toolkit, in device manager there was a Nexus 7 device instead of now "Android Device - Android ADB Interface". Can you help me get things fixed ? I'm running out of time because I'm leaving my country soon for a long time and I wanted to prepare both of my devices...
Oh and if that helps, I run windows 8 x64 on my laptop. I know some people may say that this is the reason but before i rooted nexus, everything had worked fine.
Thanks in advance !
Try and switch mode to camera instead of mtp device under storage.

[Q] Windows 7 doesn't recognize phone

I have a stock AT&T HTC One X, trying to root my phone.
I've downloaded everything I need, but I can't connect my phone via USB. I've downloaded various drivers from here and HTC Sync Manager, but that doesn't help.
All I'm getting is this whenever I connect via USB

Also, every time I install a driver, a command prompt window shows up with the words "Access Denied", spazzes out, and disappears. The installation never said it was finish, so I'm guessing it never worked.
Without it, I can't get to the command prompt of the ADB and Fastboot.
On my Windows 8 laptop, I'm capable of connecting with the right drivers, but Windows 8 isn't compatible with fastboot.

Here is log from recovery http://www.dropzone.graczu.info/recovery.log , there is actions when i trying to mount OTG and turn Sideload on.

Flash an older version of TWRP? Why do you need sideload access?

LG G4 Problem with driver

Hello guys!
I am trying to update my LG G4 to Android Marshmallow but no success.
I am doing everything as is wrote in guide, I tried to search internet for help and nothing works
When I reboot into download mode, pc does not install drivers.
I have latest LG Drivers, LG Flash Tool 2014, KDZ file, Windows 7 64-bit
I am using original USB cable, different cable, different ports, latest drivers (tried also older ones)
I tried to restart PC couple of times as well as my phone
I have got this error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
This is how Device Manager shows my device in download mode:
Tried also manual installation of drivers:
i have exactly the same problem..... but i think that something happend when i trait to use the LG Flash tool..... before i try to update... my drivers have been working fine
@nothingfacey yes me too and its normal he recognize on bridge for example .and when you try to flash for roolback you cant . first bcz there are anti rollback on the motherboard and second because for the moment the flashtool need to be update because the dll on the kdz is not the same
I am having the exact same problem and I have yet to find a fix.
I noticed that I could get ADB to temporarily work after switching to/from MTP/PTP mode multiple times randomly with unplugging/replugging. It would be interesting to see if anyone has found anything reliable.
Have you tried LGUP? That does everything automatically.

G3 not detecting usb when connected to pc and not showing charging sing with charger.

The problem started yester day when I updated my D850 (at&t) from kitkat to lollipop. By going to settings→ about phone→ software update.
Once updated to lollipop I connected the phone to my pc running win 7 with original lg cable. However it did not show the usb connection on the phone or laptop, it did not even who the charging sing on phone. So I opened my phone and there was no damage to usb jec. While powered off I connected the usb cable it showed charging when I turned it on it did not show charging sign but after an hour it charged 30% on charger.
I updated it again using the same way it went to build 21q but did not fix the issue. Reinstalled the lg drivers on pc but no luck. Found the tot 4.4.2, failed to downgrade it because there was not com port showing in device manager. Factory restored it, hard rested it, no luck. Tried to root it via akp app but failed (towel root, stump root, Iroot, kingroot).
Enabled and disabled usb debugging, but no luck.
Installed android SDK manager however I do not know how to use it.
I want to flash cloudyG3 2.5 on the device.
Plz help I am out of ideas after spending 14 hours trying to find a way.
I also tried to manually add the port in device manager. There is no option for lg devices and I do not know the configurations to manually do it. Could not find the .inf either.
