Well Said!
:D

Short answer: No, this can't be used anymore, are you blind? Read the great big text at the top of the page!

Longer answer: This hack was broken well over a year ago. Making it work now is extremely difficult and probably not worth the effort, even if possible. However, if you really want to try, you'll need to meet all of the following conditions:
* Your phone is a gen1 WP7 (HD7, Surround, 7 Pro, Mozart, Quantum, Focus, Omnia 7, Venue Pro, and a few others, but *NOT* gen 1.5 phones like the Arrive)
* You have a very early stock ROM for your phone (build 7004 or 7008 are the only ones that are known to work).
* You are able to flash that stock ROM (this requires a flashing too that varies depending on the OS and a working flashing mode in the bootloader, or a Zune restore point for one of those builds).
* You are willing to hard-reset your phone, or at least revert it to the state of your 7004 or 7008 backup (if that's what you have; if you flash a stock ROM you'll lose all data).
* You've downloaded the ChevronWP7 Unlocker tool and its certificate (no idea where you can get working links to them; maybe somewhere in this thread but I haven't tried).
* You understand how to set the clocks back to make the expired certificate work.
* You don't mind either staying on pre-NoDo, or you have a way to re-dev-unlock as you upgrade (certainly Mango, and I think also NoDo, will reset your hacked dev-unlock).

If you have all that, go to town. Personally, I suspect that's not worth $99 of my time and effort, so I'd probably just get an AppHub account instead, which will give you the exact same level of unlock...

More to @lsguntu than to you @kms108, but a bit of both. This is *NOT* the right thread for almost anybody, even if they have a theoretically compatible phone. The number of hoops one must go through just to unlock in the first place, and then to keep the unlock while re-upgrading, is ridiculous.

The correct threads, really:

I know it's a long process to unlock the phone, it was a few months back that I unlock a samsung focus from 7004 just to add asian language aside the default 5 european language then upgrading to mango just for a freiend, it took about over 1 1/2 hours.

And yes I do have all the roms, tools etc to perform the task.

I have done the developer unlock and am limited to 3 sideload apps. Also I'm unable to install anything else like apps and tweaks in bazaar because I'm not fully unlocked. Any ideas?

Sent from my Lumia 900 using Board Express

GoodDay, my phone recently re-locked for whatever reasons MS deemed fit to follow Apple's failed jailbreak approach. Until this morning, my phone was dev-unlocked using your xap [HTC Interop Unlock v2]. I even had ur oem Nokia trick working. This morning, I get the "app has been revoked by MS......". Not even Adv config works. Do you have any idea what trick I can use to reset this on the phone? since reg editor doesn't work and Adv confi closes as soon as I launch it [after the phone has relocked that is].

Thanks in advance.

Well, not this, for sure (not unless you want to roll back to 7008...)

If the "interop-unlock" entries are still in your Connection Setup list, you can use those again. If not, you'll need to dev-unlock the phone first so you can re-interop-unlock. Currently, we don't have a way to dev-unlock an HTC phone except by the official method (AppHub account).

    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

    [Edit 20th January 2011]

    Want to keep your unlocked HTC from re-locking every sync? See 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 :)

    aaahm.... I guess I have something for you :)

    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)
