M9 Unlock Token Verify Fail?

Not new to the scene here, just getting back into it. My M9 is giving me trouble; I've been through all the threads Google knows about in English and other languages.
** This is a "One M9 Unlocked" GSM phone; not developer version or carrier-specific **
[KillSwitch] Last Byte is 0X01, enable unlock - I enabled the bootloader unlock option in developer settings.
Using Download mode, as this is the new correct way. fastboot devices works and get_identifier_token works.
I tried several unlock codes from HTCDev.
Tried rebooting and all combinations of rebooting + getting new code.
Tried HTCDev fastboot.exe and android platform tools fastboot.exe.
Tried cmd and powershell.
Tried different folder locations (desktop and C:\Android)
Note that every time I get_identifier_token, the token is different. I don't remember if that's normal.
I've used HTCDev to unlock many devices, never had problems.
Output of every attempt to flash unlocktoken:
Code:
C:\Android>fastboot.exe flash unlocktoken Unlock_code.bin
sending 'unlocktoken' (0 KB)...
OKAY [ 0.016s]
writing 'unlocktoken'...

(bootloader) [KillSwitch] Last Byte is 0X01, enable unlock

What am I screwing up here?

I am confused. Why are you trying to unlock a phone that is already unlocked?

Thanks for your question: It is the factory carrier unlocked version. It works with any GSM card without needing a carrier unlock code - however, the bootloader is still locked. Whereas it's nice to not be tied to a carrier, I'd also like to get involved with cyanogenmod again.

For whomever else finds themselves in this situation: Good luck, I have no idea what happened.
I tried and retried this process several times. Finally gave up in exasperation and tried later on a different machine because that makes no sense but why not... Here's my winning magic combination (that I already tried, but on a different machine)
Front panel USB port.
Complete HTCDev unlock procedure with caveats:
I used the Google Bootloader Interface driver; HTCSync has never been on this machine.
I used the Google platform tools fastboot application.
Everything else exactly as HTCDev prescribes.
Do this on two totally different machines; it might help to be exasperated the second time. Did literally nothing different... on to the roms now.

what is missing ?

This does not belong in development.

@osamaxosama
In developer options, you have an option called OEM unlocking. This should be checked.

didn't work
still the same, same msg also
i receive on my phone that download is 100%
and at the botoom of the screen " under flash "
it didn't take me to the bootloader next screen.

Pretty sure the token has to be obtained after OEM unlocking is checked, try a second token.

Activate the OEM unlock, obtain the unlock code.bin after that, make sure that you are using htc_fastboot, not other thing, and (I am not 100% sure, but other members can help) go into download mode, not into bootloader when you flash the unlock code.bin

i did this exactly. but to let you know, i couldn't get the token when on fastboot, but after entering download mode, i was able to get the token.
also, i tried to flash the token on fastboot, but didn't flash, only on download mode i was able to get the token and flash it.
on cmd i still get the same msg, but on my htc screen i see this " attached picture " " download 100% "under flash
ad everytime i press the power button, i see another " under flash " msg.

What happens if you press the power button.. try adb to reboot recovery/bootloader??

solved
i tried on another pc.
the issue seemed to be from th sdk folder.
i tried 15 seconds installer, i knew it was the problem, because it runs from everywhere, i think it doesn't recognize flash commands or the file destination.
thank you all

why you don't go to http://www.htcdev.com/bootloader to open it
I don't know if work or not cuz I not get the phone and never use htc before

double check you have entered your serial number etc correctly on the htc dev site, any mistakes will generate the wrong unlock code.

That is the website I am getting my unlock, I am a long time HTC user and I have done this hundreds of times, the thing is just not working out for me this time, but thanks for trying to help

Doesnt HTC 10 also have option in developer options to block bootloader unlocking?
Here on mine M9
OEM unlocking
Allow the bootloader to be unlocked (unchecked by default)

I'm having the same problem. Allow unlocking is ticked

Did you allow unlocking before you tried?Or after it failed u tried ticking it on?
Because if u allowed bootloader unlocking you need to generate new unlock token all over!

Before. I've tried several times, still can't get it

Well try contacting HTC support than.

Just got it to work. Not sure what exactly solved it. Did another reboot of the laptop, used Chrome instead of Microsoft Edge. Waterfox (Firefox) didn't work properly with HTC Dev, so not sure what was going on.

No OEM unlock on the Verizon 10 in developer settings

not sure that was reason but used Microsoft edge and it worked Thanks!!!!!!!!!!!!!!

Surprisingly, I am running into this issue as well. I have done this several times before and never had this issue. I am doing it on Linux and I have done it from Linux before. The developer option for unlock is enabled.
I have tried several times now, with different browsers, and the same result.
Does anybody know how to get out of the download mode? I can't even reboot this device at this time. Holding power does not power off - fastboot reboot helps.

yes I was in the same boat. I had to generate 4 unlock.bin files till it finally accepted it.

Looks like 4th time is the charm... It finally did unlock it.

Power button and vol down held down for a while will reboot it. Also, "fastboot reboot" will do it too.

I had the same thing happen to me. I rebooted the phone, went into developer settings to verify OEM Unlocking was checked (it was). Powered off the phone, held down volume down, took it into download mode and tried again. This time it worked. I only ever got one Unlock_code.bin file, so I know it was good even when it was failing.

Make sure you are including the <<< >>> lines, both above and below? Off the top of my head I cannot remember what they say, but there are lines of texts before the code begins and after it ends.

Same here, it was the third time for me, but I did notice each time I'd run the get_identifier_token, that the token would come out differently each time. Eventually submitting through Edge got me the proper unlock.bin
First time Firefox said invalid error
Second Chrome said success, but unlock bin did not work
Third used edge, Success, unlock bin worked.
This was not this much of a pain on both Motorola Moto X and Moto MAXX

Error while unlocking phone

I just bought an HTC One M9 - Developer edition. I wanted to unlock it and followed all of the directions from the HTCDev site. The only difference was that I used the fastboot program from my Android Studios instead of their fastboot zip. When I run the command fastboot flash unlocktoken Unlock_code.bin, I get an unusual response:

When this happens I am stuck on a screen that says "download 100%" and "Start downloading" highlighted in blue. The HTCDev site says that I should get a pop-up that says whether I want to unlock the bootloader, but I just get stuck here. I know how to get out of this screen using the up arrow and power button. What I'm trying to figure out is how to actually unlock my phone.
Any thoughts?
P.S. It may be worth noting that I fully updated my phone beforehand so I don't know if its setup to work for an easier version, but fails for 6.0

If u got a dev edition it's already unlocked.
It says u are unlocked.
If not, check the oem unlock in the developer settings.
Good luck!

Okay, I guess I'm trying to turn the machine to S-OFF then. I still don't have root access (or at least that's what titanium backup says). Do you know of a place with instructions for that?

Security status stuck at S-DBG

Hello everyone,
(was trying to ask this questions to dev thread but my "clearance" is not high enough
I recently played with my HTC10 - unlocked bootloader, did S-OFF, changed CID, etc - well, all that normal usual things
At some point later I decided to go back so I removed root, changed CID back and was trying to put security back to S-OFF when I accidentally used command
fastboot oem writesecureflag 2 (instead of 3).
At the next boot the phone showed me some strange window with some Chinese text, asking me for a password. I put 0000 and the phone told me that the password was Ok, but my data could not be decrypted. It formated everything and that was Ok, but now my security status says "S-DBG".
Now I can't change CID or MID, when I try it tells me:
[email protected]:~/phone# fastboot oem writecid HTC__621
...
FAILED (remote: WRITE CID PERMISSION ERROR)
finished. total time: 0.022s
If I try to change security level to anything, it gives me:

I tried to use SunShine to reset that but the program told me my phone already had "S-OFF" whereas in fact it does not
Does anybody know what that "S-DBG" mean and more importantly - how to go back to either S-OFF or S-ON??
Thank you!

He is one of the Sunshine devs and I'm mentioning him here so that he sees this post. No need to PM him

I assume you are the same user that opened a support ticket with us. SunShine wasn't written to work with devices in this state. If you want to change your security status you'll need to use another (hardware) solution.
