I am running Windows 7 on my computer and after unlocking and rooting my phone I can no longer get ADB to recognize my phone. I have rebooted both my phone and computer numerous times, and even changed/tried numerous different usb cables and nothing seems to work. Any help would be greatly appreciated.
Thanks

Earlier i was trying to flash a custom ROM and i accidentally deleted my whole OS... My problem is that every time i plug in my device it comes out as unrecognized. I have tried installing all the drivers from Nexus Tool Kit and i still get the unrecognized notice. I've tried plugging my device on three different computers and still nothing. I've tried just about everything i could read about in the posts but nothings worked yet. If anyone could please help me with this id really appreciate it!!!
I need some help guys.
My Nexus 7 all of a sudden stopped sending data through usb OTG and i tried to erase cache through TRWP but ended up deleting the OS. Now I am stuck with a device with no OS. I cannot mount the USB for my computer to recognise it so that I can restore it. I tried ADB sideload but it doesnt load and gets stuck on starting...
If I click on Mount, I cannot click on the USB-OTG box. My computer does have the correct drivers for the USB as it used to work on it before but since the OTG stopped responding to data I am now stuck and cannot push a restore image to the device.
Any help would really be appreciated.
Many thanks.
I've tried almost everything I can think off. I tried different OTG cables, different computers. None of the computers even detect a device as plugged in. Whether I boot into bootloader or recovery I just cannot get the PC to even acknowledge the fact that something is plugged in. As a result I am just not able to flash it at all. I tried NRT with the soft-brick option but that fails too because it says no adb connectivity.
any help please?
I'm currently on H91810j and decided today to finally root my device.
I was able to get turn bootloader on, but after that, it's been downhill
I've tried:
deleting the adbkey/adbkey.pub file
2 different LG drivers
multiple usb ports
multiple methods of alternating between different usb connection methods ( midi, charging, photo transfer, etc)
factory restart
multiple restarts on pc and phone
kill and start adb server
revoke usb debugging authorizations
I've run out of ideas at this point. I've tried other suggestions from past threads, even for different devices with no success.
I'd appreciate the help as I haven't found someone who's gotten this far without solving the issue, so this is new territory it seems.
Thanks in advance

Click to expand...
Click to collapse
okay so i revoked first, then i disconnected from usb, power down device, power back on plug in then click charge only again then it should pop up for you to connect to pc from phone, CHECK MARK ALWAYS hit okay.
or skip windows bs drivers and OS. and download FWUL live USB. there is a forum on XDA just type Lglaf H918 and follow the steps to making the fwul usb. linux doesnt need all that fun stuff to get the job done like windows.
hello I'm really hoping somebody can help me because I'm not getting answers anywhere I've halfway through a course to learn mobile tech repairs and I'm completely stuck on a Samsung SM g925a when trying to remove the FRP. I have written my class instructors and I'm not getting any response. I've downloaded all the drivers from Samsung I've updated them all but however it is not allowing me to connect the device to my PC so I can get it into odin to flash combination files. When I plug the device in to my windows 10 pc I receive a pop up saying the last USB device you connected to this computer malfunctioned and windows does not recognize it and then in device manager when I open it it shows as unknown USB device device descriptor request failed. I tried to download the drivers again reinstalled and updated them and that didn't work. I changed all my cords tried it on every Cord I had and it didn't work, yet these cords recognized other devices I had. I also uninstalled the USB driver and then I ran the hardware troubleshooter still got nothing and then I also disabled fast startup none of this has worked. I also have spent countless hours researching on line and I'm just not getting any answers and I get the same troubleshooting ideas I've already tried however I did come across a program USB debugger r but I don't know if I had just downloaded it wrong or had the wrong firmware files but it wasn't working for me I thought maybe that would help me to connect to PC. I'm still learning and only halfway through the course but it seems like this is such an easy issue that I just can't seem to figure out is there anybody out there willing to help me figure this out please I'm sure something simple Im missing or forgetting but I've been dedicated to this phone and I sure can't figure it out it's stopping me right at the gate. Thanks in advance
