Windows 8.1 Fastboot

I'm on a fresh install of Windows 8.1
Here's what I did.
1. Installed HTC Sync Manager
2. Installed Minimal ADB and Fastboot
3. ADB works fine, boot into bootloader.
4. Windows shows Unknown USB Device (Device Failed Enumeration) in Device Manager
Running fastboot devices returns nothing
I can connect my phone to view files, I can ADB on my phone, the only thing I cannot do is fastboot. Why is this happening and how can I fix it?

I just experienced the exact same issue following the same steps on my laptop also running 8.1

Fastboot doesn't work w 8.1. No workaround. You need another OS.

Uh no. I have it working perfectly fine on my Surface Pro. It has both USB 3.0 and Windows 8.1. I'm not sure exactly how I got it to work but its possible.

From all of my research, you're the first person I've heard of having it working. Any specific drivers used? I'm very curious (currently, I have to use a backup machine to push TWRP updates to my VZW One)

Same thing here. 8.1 broke fastboot. Is this a Microsoft problem specifically because if it is I seriously doubt they will be in a hurry to patch it.

I have found out something based on the VMware experience. Can somebody try it out and report back???
I feel that the fastboot problem in windows 8.1 is related to the USB port.
For those people that having problem, are you guys using USB 2.0??? If yes do you have USB 3.0 port in your computer??? The real problem maybe is that fastboot only works with USB 3.0 but not USB 2.0 in windows 8.1...

I tried both USB types, and half a dozen drivers and workarounds, and nothing.
I don't believe the dude above got it working. He is probably thinking Win 8, not 8.1. I have it working on 8.

Flash Image GUI will probably do everything you need to do in fastboot without the need for a computer. I just threw 8.1 on one of my extra PC's, I'll see if I can get the drivers going. I feel like this was answered in another thread though, I think it is in the rumrunner thread...

Just another reason why 8 is bad

i just used http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ and fastboot works on a 3.0 port on 8.1

I've just had this problem last week, and now got a solution...
Hi guys,
For anyone interested, due to something DreamerTKM said - I tried both USB 2 & USB 3 sockets on my Dell L701X laptop and both failed:
ERROR: Unknown USB Device (Device Failed Enumeration)
I did a clean install of Win 8.1 Pro and it still failed...
Anyway, I was using Windows 8.1 Pro default drivers for my system when this issue came up last week - default as in Microsoft's own out of the box drivers (drivers on the install DVD and Windows Updates) for my CPU chipset, USB chipset, etc... - my entire system (except for my nVidia graphic card!)
My laptop is now a few years old and my official "Dell" CPU chipset drivers are not compatible with Win 8.1, so I need to rely on Microsoft for these, but my USB 3 originally had Dell supplied "Renesas USB 3" drivers which I hadn't installed or even thought about installing as my USB 3 socket worked - and worked well...
...anyway, after installing the original Renesas USB 3 drivers the fastboot commands work once plugged into a USB 3 socket! USB 2 still wouldn't work though, but now my Win 8.1 laptop can do fastboot commands through a USB 3 socket.
I understand not everyone will have a Dell L701X laptop but the moral here is before blaming Microsoft and their Windows 8.1 O/S (which is truly awesome), try installing the correct drivers first!
DreamerTKM - thank you for putting me on the correct path with this!
Hopefully this post may help some of you!

guyz if u r working on win8.1 just plug it in ur usb 3.0 then it will wrk...if u put in usb 2.0 it wont!

No changes. I have read a few topics that it barely works with Win 8.1, so I will have to try it somewhere esle with Windows 7, then I'll be coming back to tell what's up.

Full fastboot and ADB support is available in windows 8.

I have been using fastboot and adb with no problems on Windows 8.1 since January. But the issue is much more than simply using a different USB port. Here is the tutorial I used. http://www.droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/ Certain security features of 8.1 need to be bypassed to install the modified drivers. Also see this guide: http://forums.team-nocturnal.com/index.php/topic/1362-how-to-adb-fastboot-in-windows-xp-7-81/ I used this just for ADB, but it looks like he's updated his guide for fastboot as well. Hope this information helps.

OnePlus 3 fastboot driver issue

I had previously rooted my OP3, but accidentally updated it with the OTA open beta update, losing twrp recovery. I'm finding it incredibly difficult to flash twrp again to reroot.
The bootloader is still unlocked, and USB debugging is on with OEM unlocked, but I keep getting FAILED messages when I attempt to flash. "fastboot devices" shows the device (as a series of numbers).
I've tried using the OnePlus3&[email protected]_radaideh, but when attempting to flash it shows the below and then fails:
error: no devices/emulators found
I couldn't get it to work on my computer at home (win10) and read about problems with the OP3 drivers being unsigned (even with driver enforcement off). I'm also struggling on win7 - for some reason, the driver is listed in the Device Manager under the hardware group TP-LINK Android Phone and I can't get it to work using the OnePlus Android Bootloader Interface (under OnePlus, Inc.) or the Android Bootloader Interface (under Google, Inc.).
Could anyone suggest anything I should try?

Win10, Update & Security, Recovery, extended Start, there disable driver signing and then do your thing. Don't reboot or signing is active again.

Thanks for the reply! I tried that and couldn't get past the issues people complained about in a thread on Reddit about Kedacom drivers (can't link).
I'm at work on win7 which I believe should be easier, but still struggling with the problem as described in the post above

Did you use the drivers coming with the phone on a emulated CD drive? These worked very well for me in the past.
EDIT: Yes, Kedacom problem is nice. But changing the driver to the unsigned one manually worked for me in the past.

Yes, I have tried those drivers (the OnePlus, Inc. ones). They worked for me when I rooted originally, I'm having trouble now though

Yep I was here aswell. Boot into driver signature mode and install the proper drivers. If you connect your device you can change the drivers. I don't have a PC next to me so I can't give you exact steps. The unbrick tool has the proper drivers, just follow the first few steps of that instruction to get it to show up as Qualcomm or something else as long as it isn't Kedacom.

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

i am on the latest twrp. will blu-spark help fix it?

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

What are the driver links if you have? I already installed the OnePlus drivers.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!

[SOLVED] MPT not working

MTP isn't working on my PC. I tried on other PCs around here, and they're working.
I was using a custom rom before that, it was CAF for android 11. ( [ROM][11.0][STABLE] CAF Android 11 for RN8/8T [LA.UM.9.x][VANILLA/GAPPS] | XDA Developers Forums (xda-developers.com) )
But I'm suspecting it's windows fault. Recently, there had been an update, and when it was updating it ran into problem, but I eventually fixed, but the result was that installed programs and configurations were all reset.
I tried installing ADB, or some USB drivers I've searched for, but none of them worked. I've also tried updating the driver throug Devices Manager, but windows said it couldn't install it.
I'm trying to install another rom, but I have to solve this issue first.
[EDIT]
I formated windows and it's now showing up here. I have no idea what caused this, but the windows update probably messed up drivers or something.

Is this something from the computer, right? It's weird, because I never had to change this stuff before. Before the update, windows was recognizing my phone normaly, but after, it didn't. But thanks for the reply, though. Things are working normaly after I formated.

yes, mybe that update was a security patch for windows, usually adb and mtp not work correctly if drive signature is enable

My tablet is stuck as an unrecognised USB device by Windows 10.

Hi there. Sorry if I sound dumb. I'm new to this whole thing and this was supposed to be my first experience with flashing custom ROMs and stuff like that. I was planning to get ready to install LineageOS on my Nexus 7 using a Windows 10 PC. Unfortunately, things quickly went south.
My first roadblock was the tablet not being recognised by fastboot. I checked online for a bit and from what I could gather, the solution was to install the Google USB drivers using device manager. I went into device manager, right clicked my Nexus 7 in "portable devices", selected "update driver" and chose the Google USB driver I downloaded from the official Android developers website. I'm not sure if this is relevant but the tablet was in fastboot mode when I did this. From that point on, my tablet is no longer recognised and it just keeps saying "device descriptor request failed" whether it's in fastboot or normal mode, and regardless of which USB mode I choose.
I tried uninstalling the driver, factory resetting, WugFresh NRT, and using different cables and USB ports. I checked for all sorts of solutions but they either didn't help or they require an unlocked bootloader (which was the very first thing I tried to do before finding out I needed to install the driver for fastboot to recognise the Nexus 7). Does anyone here know of a solution to get this working again? I'm completely stumped on what to do.
EDIT: I tested with a Chromebook and an old Windows 7 PC I had lying around. Neither could detect my Nexus 7 and the W7 PC even said it failed to install the driver as soon as I plugged it in. It seems that the driver update screwed up my tablet somehow and I have no idea how to fix it. I really don't understand how this could have happened considering I followed Google's own instructions for updating the driver.
Does anyone perhaps have a copy of the OEM driver for the 2013 N7 Wi-Fi (flo) model? ASUS don't distribute the driver on their website anymore and I'm out of ideas.

Review this thread and the solutions.
After you have fixed it, you can easily install a new custom ROM with two steps:
RESTOCK - installs USB drivers and unlocks it, latest official stock ROM
CROSS - various custom ROMs, 1-click installation, TWRP, incl root

Thanks for the response. I don't think I'll have enough time to try this today but I might as well ask. Do any of these fixes work without needing a USB connection to a PC, or if they do, do they require adb and fastboot to work? Because if so, I won't be able to use them since my USB data connectivity is completely busted no matter what I plug my Nexus into.

I just ran the RESTOCK 1 script and it worked wonders! My tablet's USB connectivity has been fixed and as an added bonus, my bootloader is now unlocked. I'll be continuing the process in Linux on my Pixelbook since it doesn't require any driver installations as far as I know. Thank you so much! You're a life saver!
