yes oem unlocking is enabled and this is the factory unlocked one preordered from HTC. Has anyone seen similar issues with their unit?

i had the same issue and used Microsoft Edge browser and it worked as per suggestion from somebody here

I'm having the same issue. Can't figure it out
Different browser did not work for me.

Think I had this issue once when I didn't copy the code into the box properly, copy it exactly as they do first line to last, I tend to have to remove some leading text from each row.

I was getting this error too but didn't realize I generated the code before checking the OEM Unlocking option dialog. The code changes once you do so.
Pasting this code in will just give you an unlock code that fails with that error message. Make sure you did not accidentally do it backwards.
Not sure how browser would be an issue.

Using the Microsoft Edge browser worked for me, but I have no idea why

I've got the same problem. OEM unlocking is enabled and I've regenerated my unlock_code.bin after doing so. I've made sure there's no leading or trailing spaces in the oem token code thing I paste in. I've tried downloading the unlock_code.bin through Microsoft Edge. Exact same error as OP. Any clues?

Took me 3 tokens

HTC one m9 wont boot into OS, and cannot boot into recovery (please help)

A while ago i rooted my android Phone as per this guide: "http://forum.xda-developers.com/one-m9/general/guide-root-install-twrp-htc-one-m9-t3061133".
Now when trying to revert to stock as per this guide: "http://www.androidswiki.com/restore-htc-one-m9-to-stock-easy-guide-and-download-links/" i got locked out of my Phone.
As soon as i locked the bootloader as per the instructions the Phone wont boot into Android OS and i cannot transfer the RUU file to the SDcard as i get the error: "error: device not found".
when trying to unlock the device via the command: fastboot flash unlocktoken Unlock_code.bin
i get:

the only things i can boot in atm are the download mode and the bootloader mode.
Please advice as how to proceed.

Can't get bootloader unlocked

Trying to unlock the bootloader, got my Unlock_code.bin file, but when I try to use it I get this error message:
C:\Users\Will\Desktop\fastboot>fastboot flash unlocktoken unlock_code.bin
target reported max download size of 800000000 bytes

finished. total time: 1.082s
And of course when I reboot into bootloader it says it is locked. Tried moving the file with fastboot and the unlock_code file to a couple different places and nothing helped, and rebooting both phone and PC. Any ideas?

Did you enable unlocking in dev options?
If so, many others who have had an issue with their unlock tokens reported that using a different browser worked for them. Search the forum, there's at least one thread on about it.

Also the error message says your unlock token is 0KB. Are you sure the file is complete?
Maybe try redownload it and verify it with an MD5 hash.

I figured it out, it was just that I copied the code to get the unlock file improperly when I was in CMD. I had to copy it, but I had to turn off "enable line wrapping selection" in the cmd properties, when I tried before to copy it I ended up copying a bunch of extra info that I edited out in notepad, and I think that caused an extra space or error to be somewhere in the code, even though it worked on the HTC site. Anyway thank you for the tips guys!

Maybe your computer automatically extracted the file or something

I had to request unlock multiple times and use different browsers until it finally worked. I believe it finally worked when I completed the process with the MS Edge browser.

go to settings, developer options, and check OEM unlocking,(tap build number numerous times in settings to activate developer options)also make sure usb debugging is checked
