[Q] [HELP] Devices won't show up in adb when in bootloader - Android Q&A, Help & Troubleshooting

Hey friends, having a hard time here for some reason...
Both my N7 (v2) and HTC One m7vzw will NOT show up in "adb devices" when in bootloader mode. They do however, show up when they are powered on. Its been a while since I've tinkered with either one in adb so I can't remember the last time it worked, but couldn't have been longer than 2 months ago.
I've tried on two Win 7 x64 machines, my Dell Optiplex at work and my HP laptop at home. I've tried switching USB ports, I've tried different USB cables including the factory cables, I've tried uninstalling and reinstalling the drivers including HTC Sync Manager, I mean, I've tried it all as far as I know... Including updating everything is the Android sdk manager, I tried installing the drivers using WugFresh's Nexus Tool Kit as well (all with appropriate reboots as well...)...
So, I don't know what the eff is going on, but if anyone could maybe she some light or share some past similar experiences that would be sweet! :good:
You guys rock, thanks all.

Bump. Anyone?

however, "fastboot devices" does show the device, which is weird, so I should be good since fastboot is working and all I need to do is flash back to stock? I won't need adb commands?

If you have a windows 8 computer laying around, watch the video in that thread I linked you, it has drivers for 8.1.

Thanks, I don't, but I did figure it out, fasboot worked just fine, just no adb, luckily I only needed fastboot commands.

adb will only work in recovery and os, fastboot will only work in bootloader
So yes this completely normal

[Q] Phone not connecting to PC

[Q] Droid DNA - fastboot on Windows 8?

I have followed about every damn fastboot on Windows 8 post I can find on XDA and none of them seems to be working with this phone. adb drivers work just fine but no go on fastboot. Anyone out there have any luck getting fastboot working on Windows 8 with the DNA?
I successfully used fastboot and adb on Windows 8(64 bit). When i first plugged in the phone, and it wanted to install htc sync, i allowed it to. Then i uninstalled htc sync, but i believe it left the drivers. Adb and fastboot worked fine.
You might also check that you are using a usb2 port (not usb3) and not using a usb hub. Both have been known to cause problems with fast boot/adb

Reinstalled latest HTC Sync from their support site and switched to USB 2.0 port. Seems to be working ok now. Thanks! Can stop using the backup machine with this phone now :highfive:

i was in the exact same position. My system runs Win8 x64 and I had my phone plugged into a USB3 port, but even when I plugged it into the only USB2 Port, it still had issues so I used my Win7 x64 Rig and it worked flawlessly.
Also make sure you don't have an app like easytether installed on the computer this if very often overlooked just disable it for the system tray in windows

I was able to select and install the driver directly using device manager in Windows 8. The driver file can be obtained from the drive that the DNA mounts when you plug it in USB. I used the windows 7 driver:
i.e. <MountedDrive> HTC Sync Manager:\Win7_64\androidusb.INF​
Hate to revive a old dead thread, but I guess it is better than posting a new one, so anyways on to my question, my only computer is a Microsoft Surface Pro, and it only had one USB port which is USB 3.0. In the last few months since this thread has been dead has there been any progress on a USB 3.0 driver from HTC, or here on XDA. ADB works perfectly but I can't get fastboot to install. I have the SDK installed correctly but I just can't seem to get the drivers for for fastboot to install.

I don't have surface so i'm speculating but, just like everything else. Install htc sync to make sure that all the drivers take cleanly. Plug in your USB and
adb reboot bootloader
when your phone reboots it should say
fastboot usb.
If it does then you are good to go, just run the fastboot commands from the same folder that your platform-tools are in. fastboot flash boot boot.img
it will say sending, then working. and you should be good.
If it does not say fastboot usb, then please post back and we will do more research to figure this out.

It does say fastboot usb but none of the commands will work, no matter what I try it will always say <Waiting for device>
And I have tried it with HTC Sync installed and after uninstalling it. I seem to remember it did not play nice with some older phones but when you uninstalled it they drivers stay there, not sure if that is still the case but thought that I would try just to see.

I've never heard of anyone with a usb 3 succesfully doing it and i've searched the forums like crazy. The only way i was able to get it to work is cuz i have two ports and the other was a 2.0.
I mean maybe im crazy but is there some sort of an adapter than could change 3.0 to output 2.0? idk....
On a side note I loved Windows 8 for about 10 minutes then dumped it and went back to Windows 7. Just saying.. I know that's not always an option.

Lol , I'm with you on that one. I had dual boot and windows 8 took over my whole computer and locked me out of my Ubuntu partition. Plus hate the fact that windows 8 integration is dependent on having a windows account for EVERYTHING.

Well aside we are off topic anyways Windows 8 on a desktop or laptop is a piece of sh#t, but on the surface this is amazing I could not imagine anything better on a tablet. The only problems are the price and only one usb, other than that this thing is the best computer by far that I have ever owned. And I would venture to say that it's the best tablet EVER! The only thing that would make it better is if the DNA would play nice with it.

Fastboot not recongnizing

Fastboot is not recognizing my HTC One. I changed my cell ID and was trying to flash the GPE RUU when fastboot suddenly stopped recognizing my device. ADB recongizes it, and so does my PC.

Just realized something.. My Computer doesnt recognize my phone while it's in fastboot mode.. Is this normal? I don't think I have a recovery. My phone still works fine. Don't have a usb otg

Something weird for sure in Win 8.1, I too went all night last night playing around, and then today, nothing. Same thing, if I open cmd and check adb devices it list's it fine, but I can't run any commands, it just says waiting for device.
Reboot and recognize. I do believe there is a fix in the international forums, going to have to pursue. Seems to me nothing really works right in 8.1 though.
I got it, if you have just updated or changed something you must go through and redo usb debugging, I changed from 4.3 ATT to Brightstar 4.3 Dev Edition, and had to go through the whole setup process, enable developer options, enable USB debugging and checked through cmd, adb devices, and viola, it's there again. Not sure if that helps you, but it did me I still stand that 8.1 is a PITA!
I have the same problem as you! I do not know what to do. Please help! Will it work if I install windows XP?

you need hboot 1.55 to use fastboot in windows 8.1 or a special intel driver for usb 3.0
look around the forums theirs lots of info on it

The Intel rapid management (I think that's what it is) driver is so hit and miss. Sometimes it worked, most times, not. I gave up and went back to Win 8 last night and was able to do everything I needed to do. Win 8.1 has issues.

[Q] Stuck in boot loop

Hello, usually don't have much issues with this sort of thing as I have decent experience with this.
I'm stuck on this particular issue though as my phone is in a constant boot loop. I was planning on just reflashing a ROM on to the device, but in the bootloader or recovery my pc will not detect the device at all so I am unable to run fastboot or adb commands on it. I have tried this on 3 pc's(2 Windows 8.1 and 1 Windows 7).
Any ideas or help would be greatly appreciated.
Windows 8 & 8.1 will not work. I used the DNA toolkit on a Windows XP laptop to get my phone out of the bootloop (when you were using the Windows 7 computer, were you using the USB 2.0 port? It's been mentioned in many posts that USB 3.0 will not work). Don't use the drivers from HTC SYNC, the proper drivers are here on XDA (just Google it).

Yes it was on USB 2.0. Drivers won't do me any good if device manager won't even detect the device is plugged in to begin with. That is the issue is I have no way to flash a new ROM because I can't even get device manager to pickup that the device is plugged in on any computer.
Until I switched to a Windows XP computer, my phone wasn't recognized either, no matter how often I updated the drivers.
Sent from my HTC Droid DNA running KICKDROID Sense 6/4.4.2 ROM via Tapatalk
You can't update the drivers for a device though until it detects there is a device there. There shouldn't be any issue with Windows 7 being able to detect a DNA.
I never had an issue with this until now and now I'm just stuck in either a boot loop or going into recovery.
I would be willing to to try XP for the fun of it when I get an opportunity, but don't feel it is necessary.
If I do a factory reset from CWM Recovery I can get into Cyanogenmod and go through the initial setup steps. After that it sits at a black screen, but I can drag the notification drawer down and get into the settings. Only have a minute or two before it reboots back into a boot loop.
Surely there has to be some way to fix this...
I managed to get it to stay on. Here is what I did to transfer a new ROM over. Since all I could access on the phone was the settings I changed a locksceen slider to the Play Store and installed AirDroid. I then transferred the file over through AirDroid.
I am about to flash it now. If this installs fine and clears up the boot loop issue then I guess that issue is fixed, but that still doesn't solve the problem with my device not connecting to the PC through USB.
Okay I managed to finally get a new ROM to flash over after some issues with the ROM zip itself. It flashed and said updating apps 77/77 and restarted and its been sitting at the boot logo for 10 minutes.
Still never got it to detect USB connection on PC either.
I don't have a single clue what to do now. Am I just out of luck at this point?
Okay I know I have flooded this with messages, but I have Cyanogenmod 10.2.1 on there and it seems to be working fine. I can reboot and it goes back into Android without a boot loop from what I can tell.
USB still does not work even within Android though. Is there an issue with the hardware itself? It charges fine.

Is MTP checked or USB debugging enabled? If not you need to check them both
Sent from my HTC6435LVW using XDA Premium HD app
Yes both of them are checked.
Have you tried downloading pdanet that will reinstall adb asking with other drivers
Sent from my HTC6600LVW using XDA Premium 4 mobile app
Yes I have. Still should allow normal file transfer without it and also at the very least device manager should detect it. I think I am just out of luck on this. At least it can still charge.
On the Win 7 machine, are you sure that USB port is good? Sorry no one asked that simple question.
Also, have you tried cleaning your micro USB port?
Sent from my HTC6435LVW using xda app-developers app
Yes, like I said other devices work fine on PC and also have tried it on 4 different computers. I also cleaned the port.
NP, appreciate the response.

ADB help E5506

Hello everyone I'm having problems with adb on this phone. I turned developer settings on, adb on but I get no message to allow adb thru computer that I would normally get on any other phone. I can get adb devices and it provides my serial # but says offline. I've factory reset my phone, uninstalled and then reinstalled the drivers updated them and still no luck. I've looked all over the Internet and I guess no one has this problem. If any of you can shed some light on my situation I'd greatly appreciate it. I came from a Nexus so I do know some problem solving when it came to adb but I've tried pretty much everything that I could think of and also tried remedies I thought may help off of Google

This is a strange one
1. Are you on stock rom?
2. Are you rooted? (If so by what method?)
3. What PC OS are you on (Windows, Linux or Mac)
I am stock unrooted C5 ultra. I am using Windows 10. Yeah I have no idea why it's showing as offline. I tried again after work yesterday and no luck. I tried other USB cords as well. It shows up as a mass storage device in windows.

In Windows 10 go to your device manager /settings/searchbox n type (Device Manager)
In device manager find your C5 select it right click select update driver/let me choose/android usb device/ Mine defaults to the "MTP Device" you have to select "MTP USB Device" click apply and try adb again :fingers-crossed:
PS: Quote me or mention me @bigrammy or i will miss your posts

Glad you got it all sorted. :highfive:
To be honest In my opinion the Sony ROM is probably the best and most stable of any of the Mediatek based phones I have seen thus far :good:
Mine has not put a foot wrong so far and everything works as it should so I don't know how anyone could really improve it
Maybe Blisspop, MiUi and CM would be some good candidates just to have some choices and most of the work required to port them over is already done for the mt6752/32.
