Yea mine does the same thing...weird if you ask me. I miss the days when we had control and enough freedom in our lives to know who the hell is doing what on our phones.

Something else happens too often when it shouldnt... Sometimes when there are no applications open,my phone seems to show a "H"(when connected to 3G). I wonder what information 'they' are downloading off our phones...lol..but in all seriousness..its starting to bother me. It seems my phone also runs abit slower as well!

found way to fix unable to connect to phone.

you'll have to go to "C:\Windows\System32\drivers\etc" open hosts with notepad.exe and remove line (or lines)

<your old ip> developerservices.windowsphone.com

save it and try to unlock again.

note that on Win Vista, Win 7, you'll have to run notepad.exe as Administrator

That's hosts file look ok already. make sure it's not read only (right click on files, properties and uncheck read-only) and make sure your mail your phone a certificate. click on certificate and install it before do the unlock.

I have successfully do this on my HD7 and LG using same computer (different day with different IP).

ok I still cant connect to the phone but i think it has to do with where i am storing the certificate... when I goto install it asks what certifcate store i want to store the cert in??? Im on Windows 7 32bit... not sure where i should be storing this certifciate though... any ideas??

Thanks in advance!

The cert needs to be installed on the phone, not on your computer. Email the cert to yourself, and then open that email from the phone. click on the cert attachment on the phone to install it.

Thank you for the answer.
I've install .net framework 4 but the unlocker still doesn't work, there are other method to unlock my Htc or other solution for my problem?

P.S. I've the same problem in Windows XP SP3

    As people may know, Chevron have removed their unlocker download for WP7 :( so I thought I'd archive it and make it available for everyone here still:

    http://www.megaupload.com/?d=JY0ZFVKD


    EDIT: Thanks to Cendaryn we also have the required security certificate :) - the easiest way (thanks to Talys) to install the cert and unlock your WP7 is to do as follows:

    1. Unzip file, and attach chevronwp7.cer (see below for file) to an e-mail to yourself
    2. Open email in WP7
    3. Tap attachment once, turns it into a shield, tap it again, goes to install certificate screen with white letters on black screen
    4. Click install at the bottom

    5. Make sure registry is modified:

    Code:
     [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsPhone\ProxyPorts]“DeviceReg”=dword:000069C5
    I think the WP7 developer tools from MS does this, but you can add it in manually (it's a 32bit DWORD)

    6. Plug in phone and leave Zune running
    7. Run chevronwp7.exe, click both checkboxes
    8. Click unlock

    Excellent video tutorial here thanks to Jaxbot

    Worried that Microsoft has relocked your phone? They haven't, look here

    Hope this helps someone.

    Possible solution to Chevron problems.

    Hello to all!

    I think, I've finally found the reason why Chevron almost never works. After a few days of struggle, I managed to successfully unlock my HD2 three times in a row, all by the same trick.
    The idea is to change the IP which Chevron emulates DURING the process of jailbreak. Here's step-by-step.

    1 - Disable LAN card in your PC (Control Panel\Network and Internet\Network Connections\ right click on "Local Area Connection" and choose "disable"). It is very important to disable ALL connections, but you MUST remember which one is used for Internet access (see below, why).

    2 - Do all the standard steps of unlock - install certificate, start WPConnect e.t.s. When Chevron fails to unlock - LEAVE IT OPEN.

    3. Start Notepad and open hosts. Delete lines added by Chevron (at the bottom). Save. LEAVE NOTEPAD OPEN.

    4. Press Win+R and enter IPConfig /flushdns , press "enter". CMD window will blink for a second - that's normal.

    5. Press Win+R again (there will be IPConfig /flushdns typed already), but DO NOT PRESS "ENTER", just leave this window open.

    6. Now the trick. Start WPConnect. WHILE it connects, continue to repeatedly press "Unlock" button in Chevron, until the black CMD window of WPconnect disappears. Chevron will fail to do its job, but that's in fact is the very thing we need.

    7. Now, do not touch Chevron window, just return to Network Connections and ENABLE yor LAN card.

    8. Go to Notepad and JUST CLICK "Save", do not alter anything inside.

    9. Return to the window with the typed command IPConfig /flushdns . Press Enter.

    10. Start WPConnect, WAIT until it disappears, and press "Unlock" button in Chevron. You're done - this time unlock would work.

    At least, it worked for me 3 times in a row, while NO other ways worked.

    Best regards - Draco.

    P.S. If you have firewall - disable it before doing anything.

    P.P.S. Win7 from NAND + MDJ Desire HD 4.4 from SD = best phone in the world :)

    Succeeded

    Okay so here is *everything* I did to succeed in re-unlocking my Samsung Focus

    1. Have Winphone developer tools installed
    2. Connect Phone via USB
    3. Wait till zune starts and sync completes
    4. Verify that zune is not in a guest relationship
    5. open a command prompt, type netstat -a to confirm that port 443 is not being used
    6. open an admin command prompt, navigate to c:\windows\system32\drivers\etc\ then type notepad hosts and delete any references to windowsphone developer services
    7. go to the settings on the phone and turn airplane mode on (so that the phone is forced to use internet via zune)
    8. While the phone is still on the settings page, run Chevron with admin privileges

    And it worked!

    If you are having issues, you should also make sure that your machine isn't running anything that may be using port 443 (including IIS, Skype, etc)
