You will see a long block of text. Copy and paste this text into the the token field below (in the Windows command prompt: Right Click > Mark > highlight the block of text > Right click to copy. Mac users can use cmd-option to mark and select text.).

https://www.htcdev.com/bootloader/unlock-instructions/page-2#

you will get a email from HTC dev with a unique token

Step 8

You will receive an email with the attachment: Unlock_code.bin. Save this file in the same folder as your fastboot files (For Example: C:\Android).

If, after a short period of time, you have not yet received the mail, or you have received an email from HTC, but does not contain an attached file, it is possible that more stringent spam filters and anti-virus programs will block this mail or attachment.

In order to ensure that you receive the email with the attachment, we suggest you consider using a non-corporate email server as corporate servers tend to have more stringent attachment policies. If you have not received the email at all, please check your spam folder in your email client to check if the email was filtered out.

Step 9

In the command prompt type: fastboot flash unlocktoken Unlock_code.bin. In the command prompt you will see the following message:

Step 10

On your phone you will now see the disclaimer. Please read this carefully as this action may void your warranty. Use the Volume buttons to highlight your choice, and the Power button to make your selection. If you select Yes, your phone will be reset to its’ factory default settings, and your bootloader will be unlocked. If you select No, your phone will reboot and no modifications will have been made.

Step 11

To re-lock your bootloader, in the command prompt, type: fastboot oem lock.

Note: This will not restore the factory default lock, but will simply re-lock the bootloader so no further changes can be made. Furthermore, if you want to unlock your bootloader again, simply repeat step 9 with your original unlock key file to unlock your phone again.

You're Ready To Go!

Congratulations! You have successfully unlocked your bootloader. Browse this site for further sample codes, examples, and tips.

Kerberos Token Bloat (MaxTokenSize)

How to reduce Kerberos token bloat

To reduce the Kerberos Ticket Size you can:

•  Reduce group membership(No need to reduce DLs , Mostly security groups)
• Clean up SID History
• Limit the number of users that are configured to use "trusted for delegation". The account that are configured  to use "trusted   for delegation" the buffer requirements for each SID may double

          How to prevent Kerberos login errors due to token bloat

To allow a user to be a member of more than 900 groups you can increase the size of the MaxTokenSize by modify the following registry key on all workstations.

 To use this parameter:

1. Start Registry Editor (Regedt32.exe).

2. Locate and click the following key in the registry: System\CurrentControlSet\Control\Lsa\Kerberos\Parameters

3. If this key is not present, create the key. To do so:
   1. Click the following key in the registry: System\CurrentControlSet\Control\Lsa\Kerberos
   2. On the Edit menu, click Add Key.
   3. Create a Parameters key.
   4. Click the new Parameters key.

4. On the Edit menu, click Add Value, and then add the following registry value: 
   Value name: MaxTokenSizeData type: REG_DWORDRadix: DecimalValue data: 48000
