I've previously managed to get my tokenID from htcdev without any problems on various handset but lately I've come across a few issues.
For example I'm trying to unlock the bootloader for this DesireHD but when trying to get the tokenID I get an error saying no devices attached.
My computer has installed the correct drivers and it shows up on device manager. I am able to 'adb devices' when the handset has booted up but when in fastboot / bootloader nothing comes up when running the same command.
Is it something to do with my Android SDK folder?
Is there a way to come around this because if I want to do similar process with other devices I need to understand what I need to do before.
Thanks

Adb does not work in bootloader, just with a fully booted device. You have to use fastboot command in fastboot usb
Hey guys,
I followed this thread to unlock boot loader (http://forum.xda-developers.com/showthread.php?t=2694600), used the automated way to install adb drivers and did everything like the post says, but when I boot into bootloader and connect to my pc, when I type an adb command to get the code, it just stays at waiting for device for ages...
What I'm doing wrong? I even updated to the last api of adb, which are on the automated post (http://forum.xda-developers.com/showthread.php?t=2588979), posted by an user.
Can anyone help me please?
Thanks in advance!
You don't use ADB at the bootloader, you use fastboot. ADB is only when Android is running

This method does not require you to boot into bootloader. It does require S-off, however. Notice the instructions only tell you to boot into bootloader as the last step, simply to verify the unlock was successful.
Confused...
What? I don't know what to next then... I installed the automated way drivers, installed HTC connect program and allowed the connection via usb in developer options... What shall I do next to unlock boot loader?
For what I see on the VomerGuide it says after:
"Enter Fastboot (bootloader) Mode" ... now you are telling me that I do not need to...
When I enter in this Fastboot Mode, I connect the device to pc and then say the command to get the code, but it says waiting for device for ages and doesn't give me the code... Can you explain me what I'm doing wrong/what shall I do next?
Thanks in advance!

Make sure "usb debugging is enabled" on your phone, then cmd "adb devices" on PC and it should return your phonr serial number.
Will try that.
BTW, shall I enter in bootloader and then connect to PC, or do the other way around?
Thanks!

My apologies. I was looking under a different page from the link you provided. If you are following VomerGide, yes you do start in fastboot.
Try this first, though. Make sure USB debugging is enabled, leave phone on (not fastboot), plug it into your computer, and cmd "adb devices". If a message comes up on phone screen to allow computer connection, choose to always allow. Once you have gotten adb to recognize device, you can cmd "adb reboot bootloader" and phone should reboot into bootloader. In bootloader screen on phone, you might have to select fastboot mode. Then try to cmd "fastboot devices" and see if it brings up you device info. If so, you are good to go!
First I must say, I searched all over the internet for answer to this problem. None of the topics I read had matched my problem.
I want to unlock my bootloader so I can flash custom recovery and get root access.
When I want to access the bootloader ("adb reboot bootloader"), in my phone all goes fine (I see on my phone the Fastboot instructions, etc). The problem is in my computer that fastboot won't recognise my phone anymore. When I want to get the device-id, fastboot is stuck on "waiting for all devices". When I want to see the list of devices, ("fastboot devices"), I get nothing, wether my phone is on bootloader mode or not.
I installed all the LG drivers, including the ADB one. I am in USB debugging mode, and I disabled OEM protection.
Android version is Lollipop.
I need help on this matter, thanks in advance.

I know mine can be unlocked. I actually can get to the bootloader via ADB. The problem is that fastboot won't recognise my phone afterwards. (I believe it's the european version of the H815 model, and according to one-click-root app, my phone can be safely rooted. Also my Lollipop version is 5.1.)
There are other few issues also:
Fastboot won't recognise my phone, even if the phone is not in bootloader mode.
Windows will recognise all of the LG related drivers including the ADB related driver, while the phone is powered on normally.
However, it fails to do so, in bootloader mode. I see non working driver in Windows 7 Device Manager, under "Other Devices" by the name "Android" with yellow exclamation mark. Nothing else.
Still looking for advice...

I have the same problem, adb detects my phone but fastboot does not. Same Phone btw
Still no solution until now ? I have the same problems
My device is H815
Hi !
I have had this problem too...solved with strong battle to understand myself...
My solution : when you have installed driver ,when your phone go to fastboot mode and the pc don't want to reconize the phone : on the pc on windows go to harware manager (config panel) and you can see in theory "android" with a "?" ==> you have to install manually the driver by searching somewhere on the harware list "android adb interface " (i don't remember where it is) ==> your phone wil be reconized ! And you will have the 2 lines of ID on the adb comand interface....and follow the tutorial...
I have read hundreds of issues with driver problems when it comes to windows.
Please try Linux instead. There are live distributions like Ubuntu available. Install it on USB stick and start from there.
No driver issues anymore. Just works.
.
@steadfasterX it need some knowledge for to use Linux OS for adb thingsv (unlock bootloader ,instal TWRP,rom,apps...etc...) ? maybe you can do a small tutorial for to help ?
For windows i have found these pictures for an eventual help (see ZIP on attach file)
@Loulou-13 , now i can see my device-id - solved -
but now have another problems, my imei is not match with my device-id ...
my device is H815

Well there are hundreds of guides out there just use google...
adb and fastboot working the same way under Linux so there is no need to have a specific guide for linux.
I haven't tested that guide here but it looks very good as a starting point:
http://forum.xda-developers.com/showpost.php?p=44739402&postcount=1
As said there are other maybe better guides but Google will tell you.

@steadfasterX thank for your link ,it's useful for people who have problem and read this thread
It's not for me .... i have my bootliader unlocked ,twrp...( and this fabulous Imperium MM rom !!!! )
I need a little help. I tried to unlock and root my phone. I was on build NDE63X. I was able to unlock the device no problem, but then ran into some issue with the root. I'm not sure what happened. Now I am stuck in bootloop.
I am trying to sideload the OTA NDE63X through ADB. However, adb isn't recognizing my device. If I type "fastboot devices" then it pulls up my device. I have tried to uninstall my drivers and reinstall the drivers and every time the driver says "Android Bootloader Interface". I don't know if that is the problem or not. Any help would be appreciated.
Thanks!
