[Q] Unrecognized Device only in hboot/fastboot

Let me say beforehand that I am a lifetime lurker. I would not be posting here if I hadn't already spent at least two days scouring the web for an answer.
My HTC Desire HD cannot connect to HTC Sync, but it can connect as a storage device, and can be seen by adb. Whenever it connects while in hboot/fastboot, it will flicker "USB" a few times before Windows tell me it's not recognized (Device failed enumeration code 43). This includes using the RUU wizard from HTC. That will just make it stick on "RUU" in the bootloader.
I have tried every driver download suggested on this site. I have switched USB cables three times (all htc cables). I have used two seperate computers (Windows 8 and Windows 8.1).
I'll admit I'm a nooby specifically to Androids. All I want to do is flash new ROMs/root my device. As far as I know this is step one, and I can't go any further until I've unlocked my bootloader.
EDIT: SOLVED
HTC Desire HD drivers really hates Windows 8 and 8.1. Installed Windows 7 32-bit and it worked just fine.

That error can be a pain in the ass. I have it as well. I believe disabling griver signature enforcement in win8 (it's your OS, isn't it?) should allow installing adb drivers, but I was too lazy to check it. As a workaround I instead flash the boot.img in bootloader by putting it to PD98IMG.zip
I can upload you a template, leave the txt in it and replace the boot.img with your desired one, choose store (none) compression level, then put the zip directly (don't use folders) in sd card
EDIT: I didn't fully read your post before. If you don't have S-OFF most probably you can't get away without adb drivers..

Turned off device signing. No effect.

Have you tried now manually installing drivers in device manager while the phone is in unrecognized state? Does it still say the drivers are incompatible?
If your OS is 64bit, you need these http://d-h.st/23V

I have those drivers. I installed them manually. I tried the updating the drivers through device manager and pointing them directly to the drivers folder I need, and Windows is insistent that not having ANY drivers installed is the best driver to have installed for my device.
I am getting a pop up saying that the device is failing to to start. It's not like other usb devices I might have plugged in and they just sit there in at least their correct category in device manager.
The part that ticks me off most, is that this exact problem on this exact model has been solved on three different forums, and each time the OP just said "nvm I fixed it" and never even bothered to explain how for the rest of us.
It's really hard not to curse right now.

in device manager update dialog goto
browse my computer --> let me pick --> have disk --> choose the .inf from the drivers path.

Ya, I had tried that too. None of them will work. It says the file I chose doesn't have compatible software for my device.
Once again, this only happens in the hboot/fastboot/RUU. Once the phone has loaded the OS it works totally completely fine, save for HTC Sync not seeing the phone and vice versa. I don't understand why some drivers would only work sometimes unless something is wrong with my bootloader, and if so, how do i fix it?

have you tried un-installing HTC SYNC?

Nothing is wrong with your phone, same thing happens to me, I just thought disabling driver signing should fix it, like I said I was too lazy to check it since I found workaround for my needs.

It is currently uninstalled.
@smoger:
I would try your workaround, but I' m not sure where to obtain the boot image I need. Also, I thought you could only change the S-Off if your bootloader was unlocked anyways?

Power down DHD and connect it to PC. I realized, my win7 was installing drivers, while phone was off.

It appears to be the same device/drivers when powered off or when in the Android environment. While in the bootloader, it shows as an unknown device.
I also noticed that only when I am trying to update via RUU, it says instead "Device Descriptor Request Failed"

The boot.img is in the ROM-zip-file packed. But I think, if its a RUU it is called PD98...img

Try this, I know its from Samsung, but this installs fastboot drivers and drivers used for ADB access

For the set of Google Drivers, go here too http://d-h.st/23V

My drivers list does not show the Google or HTC drivers like yours does after installing all the things in your links. In fact, that's the fourth time I've downloaded those Google/HTC Win7 64x drivers from people around the web. They are not in my drivers list after installing them via the INF files. I must be doing something wrong.

To be exact I have:
Tried HTC Sync
Tried HTC Drivers Installer
Tried to Automatically search for drivers
Tried to install drivers by using the inf Install option
Tried to manually select drivers by pointing to the folder the Win7 64x drivers were placed
Tried to manually install by picking out the exact inf files
Tried to install from device drivers list, were they were not listed
Tried these steps with driver signing turned off
Tried all of these steps with another PC
I still think the issue is related to the fact that it only has problems in the bootloader menu

Ok, like u know I had this issue. Now I randomly managed to fix it when I needed adb drivers for my new toy (Sanei tablet for 40$ lol)
The mistake I was making is that I was trying to install the drivers while device was in fastboot, but apparently you can get away with casual "My HTC" drivers which can be installed when DHD is booted into Android. It looks likethe phone is not being detected from bootloader (it doesn't like any of the drivers I had tried), but I can fully use ADB while it's in recovery or starting/trying to boot OS, so it should be enough for rooting/unlocking bootloader.
I remember with HTC Wildfire I had drivers package with seperate drivers for Android and fastboot, so I had to install different driver after rebooting to fastboot, but with these new drivers and win8 it doesn't work out this way.

Solved. Used Windows 7 32-bit. Windows 8.1 was the culprit.

I am facing the same problem and I too have tried different methods like you did. Am using Windows 8.
Gotta try on Windows 7. Shall update if that solves my problem too.

Adb recognizes devices during phone on state, but not in fastboot.

Okay so now that I've scanned pretty much all of what the internet has to offer on this issue, I'm helpless and forced to write a new thread here about this.
Yes, a similar question has been replied to a million times before, but absolutely none of that helped, made no difference whatsoever.
So earlier, I was on the stock rom, with TWRP flashed and root access. But wanted to switch to the community build. Tried the twrp trick to install the CB but that didn't work, so flashed the stock OP3 rom and flashed community build.
All went fine, until I tried flashing back TWRP. Used the traditional ADB method of doing that, seemed to have flashed it but tried going into recovery only to be presented with a black screen. I got fed up of that trying to fix it for a whole day so I just left it, because I could still boot into the OS and that worked fine.
Fast forward to about a week later; somehow the flash didn't work and I still have stock recovery. Now I try flashing TWRP again, but I discover that my device doesn't get detected in fastboot. It absolutely refuses to.
It DOES, however, gets detected in the OS just fine.
I've tried every which way, absolutely NOTHING seems to work AT ALL.
- OEM unlocking is checked, if that makes a difference
- USB debugging is turned on
- Uninstalled all USB drivers related to the device, and installed them via device manager (but it gave me this error:
"the folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with windows for x64-based systems)
seeing as I'm on an x64 version of Windows (its worked before with my Nexus 5, I swear)
- Tried it with different adb fastboot files, from all over the internet. All of them show just that blank space after I type in 'adb devices'
- Installed universal adb drivers.
- Samsung drivers.
- Obviously the official OnePlus drivers.
- Used Usbdeview to uninstall / force stop and re-installed the drivers.
- All in one tool
Now I'm thinking, I should try to re-lock the bootloader and unlock it again, or do like hard rest sort of things. I have no idea though, how this would affect the detection in fastboot.
Anyone have any ideas? Because I'm out of all of them, and so is most of internet.
TL;DR - Adb devices detects phone while booted in OS, but not in fastboot. Tried all methods, nothing works. Going to do lock bootloader then unlock it and try again, if not that then going to do a clean wipe and install the community build again, hoping that would work. Should I?

You need modified twrp by @eng.sdk.

I am having a similar issue. I have a brand new OP3. Everything stock. I'm attempting to unlock the bootloader and have found that while ADB recognises the phone, Fastboot doesn't. I'm pretty sure it's a driver issue and I have no idea how to fix.

it seems to be a problem with adb Windows 10 IDK

I'm afraid you've missed the point, my friend.
If the phone does not get detected in the fastboot, it means I cannot flash anything, period. No original TWRP, no modified TWRP.

I had this exact issue and fixed it.
Fastboot would never see my device, no matter which driver package I tried or no matter how I tried to install or force the correct drivers. Turns out Windows 10 (and Windows 8) has a feature that completely prevents installation of unsigned drivers, which blocks the fastboot driver. If you're seeing "Kedracom" or "Android Device" in the device manager, then your driver is NOT actually installed. This is true even if Windows doesn't throw you an error message during install, or if you appear to force the installation. Even though it looks like you're doing the install correctly, Windows just ignores your unsigned drivers.
You need to temporarily disable the security feature to permit installation of unsigned drivers. This involves invoking a special restart function. Here's the howto for Win10: http://www.howtogeek.com/167723/how-...igned-drivers/
Once you've done this, on the next reboot you can do a forced install of the unsigned fastboot drivers you downloaded for the OP3. And simply rebooting your computer restores the security feature.

It's mostly because of the windows security over unsigned drivers.. Try the above method or just the cmd way..

OP3 Not Found By Fastboot (Win 10)

So I'm running windows 10 on my pc and my op3 is easily found by windows. When I enter fastboot mode on my op3, the command "fastboot devices" doesn't show my op3. I used that 15 sec adb & fastboot installer.

Have you enabled oem unlocking from developer options?

I'm having the same problem. After going back to Oxygen OS (now 3.5.4) from MIUI 8 fastboot just doesn't work anymore. ABD works just fine (tried on Minimal ABD and Fastboot on Windows and ABD installed over Android Studio on Ubuntu. Fastboot did recognize the phone on Ubuntu but flashing TWRP resolved in a bootloop (tried the old and the new recovery image).
All drivers are installed on both Windows and Ubuntu (I even removed all drivers on Windows and added them again) and just to make sure everything gets installed I disabled driver signature verification on Windows, but as I said - still no luck.
Edit: Of course USB Debugging and OEM Unlocking is enabled (my bootloader is also unlocked since I already had tried out multiple roms)

Had the same Problem, Win10 is the Problem + the old OP Drivers + the new Update to Win10 etc.
Nothing worked, tryed everything. Created a Thread last week here also...
After that i created a new Partition and installed Win7 on it. All works fine, only thing is while Boot ur System u have to pick ur OS or it waits 30sec to boot up but thats ok.
Now i have Win10 for everything and i reboot to win7 for Fastboot/OP3

Can't solve your problem, but OP3 fastboot does work in Windows 10. I did have to disable driver signature verification to install the driver in the first place, and you'll have to leave it off for the driver to stay functional, but it definitely works on Win 10.

I dont tryed ur Way, so yes after disable Driver sign. it works like u Said but i did not Test it.

i had the same problem to find the correct adb driver spent many hours but it didnt work so after that last i try to update windows 10 and find adb driver there after updating window its work like charm so all u have to do is just connect ur phone with data transfer mode on and search the window automatic updates .

Same here

It's driving me crazy. I've updated from a rooted stock OS (incl TWRP) via full OTA directly to 3.2.7, which removed TWRP and root.
I now cannot enter a Fastboot mode which detects the USB connection. Thus I can't flash TWRP again and can't root my phone, making lots of apps unusable.
I've tried every suggestion on every thread but nothing works...

Rebooted both devices, OP3 was in fastboot. Then there was a Driver called Oneplus Bootloader Interface (or something similar)

Yeah that one. After disabling the driver signature verification you have to re install it, when it's not disabled windows just doesn't install it although it says it does. After I disabled it Windows actually showed a completely new window during installation to install the driver properly

I went into device manager and phone was listed as Marshall London bootloader interface so automatic driver update then updated it to kedacom bootloader but it does say adb on the drop down. I'm stuck as how to get my device to show on adb/fastboot devices?
I'm currently on win10 and as no luck of installing secondary win7 at the moment

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!
