Hey all,
Long time no post.
I have an issue with my grandparents' Slate 21. The bootloader doesn't boot into OS. I'm no super tech nerd, but I have done Android reinstalls on Xiaomi Pocophone F1 and Samsung Galaxy S4 I-9505 with TWRP.
To install TWRP on the Slate 21, all you need is a male-to-male USB A cable and ADB.
My issue. I have downloaded many drivers (ADB&Fastboot, Google USB driver) and used methods such as
updating "Fastboot" driver software via device manager to a specific driver
manually installing drivers (Right-click -> Install)
switching USB ports
When I type in
Code:
fastboot oem unlock
or ANY
Code:
fastboot
command I always get
Code:
<waiting for any device>
. I have tried everything, so I came here as a last attempt. I will give any info you need because my grandpa needs this Slate.
Some info:
I installed ADB and Fastboot via the "15-second installer"
Fastboot loads correctly on the device itself
I cannot access Developer options because it doesn't load to OS
I use Windows 10
Love,
Nerijus
Simply installing drivers you don't know what they are meant for makes no sense at all, IMO:
Google's USB driver you installed is only applicable for Google devices ( e.g. Pixel, Nexus ).
You have to install the "Android USB Driver" suitable to mentioned phone.
BTW: To get the most accurate ADB & Fastboot drivers use my tool what is linked to in my signature.

The issue might be USB 3.0 ports.

If you say so ...
IMO your issue has nothing to do with of what type an USB port is.
The differences between USB 2.0 and USB 3.0 are
You can transfer data at up to 4.8 GBit/s with USB 3.0. That is ten times faster than with USB 2.0, which has a maximum of 480 MBit/s.
USB 3.0 works full-duplex. This means that data can be transferred in both directions. With USB 2.0, you can only transfer data in one direction at a time.
The maximum cable length with USB 3.0 is limited to 3 meters. USB 2.0 cables can be up to 5 meters long.
Never heard / read that ADB & Fastboot drivers depend on type of USB port.

My laptop's USB 3.0 ports completely failed to unlock Xiaomi Pocophone F1's bootloader. Meanwhile, my old PC did it easily on the first try and it has USB 2.0 ports. Weird. Might be the reason.

I am trying to connect my G3 to Android Studio, but no devices are listed by ADB or the Android Device Manager. I turned on Developer Options and enabled USB Debugging.
I tried:
Switching between PTP/MTP
Reinstalling drivers
Using another computer
Updating the SDK
Plugging in another USB port
Rebooting the computer and device
Is there a step I am missing?
Thanks
EDIT
Found a specific version of the driver that includes ADB. My account can't post outside links, but search LG G3 USB debugging Driver and go to the androidsoul site.
I installed the drivers from LG PC suite and adb worked fine for me
went through the same issue.
keep trying different USB cables. makes no sense, but solved my problem
yo xda.
USB file transfer is dead on my phone.
when i plug the phone to a computer, it charges, but i have no choice for USB file transfer (MTP or PTP) that was just there in the notifications bar.
i tried with 5 different computers (win7 and win10), and 2 usb-C cables (the xiaomi official one, and a brand new samsung usb-c one, no luck).
Is it possible the USB transfer stuff is broken in Android sofware-wise???
I have magisk only for systemless hosts, to suppress tha ads, nothing funkalistic . Stock rom, stock (unlocked) bootloader.
USB transfer just stopped working without warning.
I reinstalled drivers without effect. No USB file transfer thing in notifications .
One more very weird thing is that i can still fastboot to the phone. So i think the cable works as intended.
>>>C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
>>>2871d3b5 fastboot
How to reactivate the USB thing? Maybe i disactivated by error...no clue, really.
aaand flashed full stock funkelnagelneu fastboot rom.
i gained an OTA. but still; adios USB MTP or PTP. ftp, here i come.
why fastboot works, and not usb transfer, is a mystery.
Upon connecting my Nvidia Shield K1 Tablet (2017) to my Windows 10 machine I get an error:
"The last USB device you connected to this computer malfunctioned, and Windows does not recognize it"

First thing I did was enabled USB debugging in Developer Options, Set USB Configuration to MTP, swapped cable, and swapped USB ports
I have followed the instructions at https://developer.nvidia.com/gameworksdownload#?search=SHIELD Family Windows USB and keep getting the error:
"The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it's designed to work with Windows for x64-based systems."

I have also attempted to use the "CodeWorks-1R8-windows_b181" aswell which seemingly installed the same USB drivers but still same error.
ADB Devices and Fastboot Devices do not show any devices detected.
My phone is getting detected using same cable, I don't understand what else to do other than find x64 Nvidia Shield USB drivers but all the resources point to either of the 2 softwares above. Is my only other option making a Linux Mint bootable?
Other System Info:
Windows 10 Enterprise
AMD Ryzen 5 2600X
16GB RAM
I have made a Linux Mint USB bootable and installed ADB/Fastboot and still it will detect my phone but not my shield. I'm just using some Galaxy S7 cables, Ive seen on other forums that the shield is picky about cables for data transfer but could that really be the case? I'd test it but I don't have a premium cable laying around
Hello all,
My OnePlus 7 Pro, can't recognize USB through my Windows PC, I don't get the prompt to connect to my Win PC.
Also I enabled ADB with Developter Options. I go to fastboot and also after adb devices and fastboot devices command, he can't recognize my device.
My OnePlus 5T is working with ADB and normal USB Win PC, tried two cables and laptops.
I did an run Android 10, now 11, beta etc nothing works! The phone can charge etc.
Please help. Reset etc tried also.
it is known issue ADB don't work on USB 3.0 ports
just goto BIOS > Advanced > USB > XHCI and change the setting to Disabled.
This will make the ports run in USB 2 mode, and fastboot and ADB works as usual.

Can't confirm this. At least latest version of ADB works at me with USB 3.x ports.
Nvm I didn't read the thread well if the PC can detect the other phone on ADB perhaps you can try "revoking USB debugging authorization" so it would ask for permission again
Hello,
I recently got a Pixel 2 on stock Android 11 with the intent of flashing LineageOS + rooting. But I haven't had any luck getting ADB to recognize the phone so far. I am using Windows 10 and Ubuntu Linux 20.04 LTS.
As a prerequisite, I enabled developer options, USB debugging, and OEM unlock.
I'm pretty sure the USB port of the phone is okay because the phone still fast charges.
Here's what I've tried:
- using Minimal ADB (device does not appear when adb devices is run)
- using platform-tools ADB (same as above)
- using wireless ADB (ADB is able to pair but the phone still doesn't appear when adb devices is run)
- checking Device Manager (device does not appear)
- Installing Google USB drivers
- using OEM cables from Samsung and other Android OEMs
- using a micro USB cable with a micro-to-C adapter
- using a USB hub
Am I missing something? What should I be doing to get my phone to be recognized by my computer?
Thank you in advance.
Hi, sounds like you've tried all the usual trouble shooting bits with cables, ports etc. Only other things I can think of at a stretch are to try enabling file transfer when you connect to a pc and see if that makes any difference or booting into bootloader via the button combo from powered off and then running fastboot devices from your adb and fastboot to see if it is recognised in fastboot mode?
