Windows Phone 7–Free developer unlock anyone?

I’ve been working on a little project with some mates to “free” the Windows Phone 7 OS from the marketplace shackles. 

Rafael & Long

Basically what you needed to do was pay Microsoft $99 (USD) or $150(AUD) to gain “access” to the device you paid for, so you are able to deploy applications you have created.

So what we created was ChevronWP7.  An application that runs on your desktop and unlocks your phone.  Head over to the website for more information.

If you have any questions feel free to ask them here or at the link above.

Didn''''t work - I just get (I did follow all the steps nd yes zune is running with phone visible):


Uh oh.

Sorry, I''''m having trouble communicating with the phone.

  • Please make sure it''''s connected using USB

- Please start the Zune application

OK

25 Nov, 2010 03:34 PM

Gordon, What operating system are you using? Close the app and re-open it and does it say "unlock"?

"Your phone is locked with a pin. Please unlock the phone and try again" How?

25 Nov, 2010 03:58 PM

That means you need to unlock the screen on your phone. That is all it is asking.

Hi Chris! I ve a HD7 and on PC Win7/32 Before insert the reg, and start ChevronWP7 there comes directly the error message "Uh oh. - trouble communicating with the phone".

After insert reg file and restart the pc i can start ChevronWP7. It shows me the window with the Preparation checklist. Marked both entrys and klick on unlock. Then comes the same error message as above.

I ve really installed the certificate on phone.

I agree, an opensource version would really help It was hard to find the 2 issues I had : -hosts file write access -https port already used

Still, thanks for this wonderfull tool, you did a great job. It''''s very nice to be able to test our applications on device

Hi guys,

I have the same problem... I have followed all the steps: -certificate installed -zune full sync- -registry key is there (I have browsed it and it has correct value) -pretty much stoped all the uneeded services.

I get message that my phone is PIN locked (it is not). Sometimes I get the ChevronWP7 window open but then when i click unlock it gives me this message again. I am using HTC HD7 on windows 7 x64. Please could you help?

If one needs to re-lock the phone how is it done?

For example, if you decide to join the $99 developer''''s club, but MS decide that Developer Registration will only work with a locked phone.

if you are trying to re-lock it, simply re-run our application. Gives you a prompt to re-lock it.

3 days later, after ticking both boxes on the checklist page, I still get the "uh-oh" error. Got the dev tools, checked for anything using port 443, installed the cert, ran the reg file.

I get no dialog asking for a SIM unlock code, so I assume that''''s not it. So how do I install this? My o/s is Win 7 x64.

I am an idiot. The tool clearly states, "install cert on PHONE". I''''d installed it on my laptop. Read a post saying "... on phone''''s browser", penny finally dropped, installed it on phone. SUCCESS!

Now, how do I get an app to install?

Eric, It''''s not a decision of the people it''''s a decision between Chris and MS. I think it''''s the right choice at the moment. Microsoft needs developers for WP7 and their marketplace and if this is a chance to open the system, give them a little bit time to discuss about it.

My hope for a more usable and more administrative device in future is activated :))

So we have to wait for some cool tools and tweaks which will enhance the experience on wp7 devices.

With that point of view i''''m not angry that i ve bought a wp7 phone :))

Big applause to Walshie and Co. and MS for understanding what near 30 percent of users really want.

Hope that some well known developers jumps on the wp7-train now :))

Ok, for this tool to work you need: 1. Install Windows Phone dev tools 2. Put your phone's screen timeout to Never or Disabled 3. Close all other apps on your computer: yahoo messenger, skype, outlook all. 4. Open zune and change Relationship from 'Guest' for your phone (just follow the onscreen instructions, it's easy) 5.Disabled you PIN in the phone: Settings/Slide to left/ chose Phone and at Sim Security turn off 6.connect the phone to your pc with only zune running on your computer 7.Check the 2 boxes on Chev's program and click Unlock.

To prevent relocking do this: 1. Open Windows\System32\drivers\etc hosts file (with Notepad!) 2.you will see there the line saying developers.windowsphone.com...blablabla, delete them and put this: 127.0.0.1 developerservices.windowsphone.com 127.0.0.1 developerservices.windowsphone-int.com After this go to this file Properties/Security and uncheck Write, Modify and Full Controll for every user listed there (you may have to click Advanced, and uncheck Iherits permissions from parent folder...) 3. Go to services.msc and change the startup mode to disabled for Zune Windows Mobile connectivity service. 4. Go to forum.xda-developers.com and download the files neede for your phone to prevent unlocking.

Until you install the files on your phone, turn off/turn on your phone DO NOT Update your phone with pre-Nodo or Nodo.

Although dev unlock was useful, I just had some problems with MySQL server on my PC. It wouldn't allow me access to admin tool because it tough I was accessing from developerservices.windowsphone.com and not from localhost. Thankfully I managed fix this by deleting lines added to hosts file.

for all who are having issues i found a way that should definately work.

http://www.microsoft.com/downloads/e...displaylang=en download from the above link. install first.

Once you installed whats above then do the following:

  1. Connect Windows phone 7 (HD7 for me)
  2. ON THE DEVICE go to http://www.chevronwp7.com/cert and install. Lock the phone and leave it.
  3. edit the properties of ChevronWP7.exe (I am running windows 7 64 bit.) a. Run in compatibility mode XP SP3 b. Run as Admin. c. Apply those changes and exit. DO NOT RUN IT YET
  4. Start up the Zune software, and make sure it detects your phone
  5. Run ChevronWP7 (If you get the pin code error, simply slide the lockscreen up so you can see the tiles, and run the program again.)
  6. Then click all of the check boxes and unlock There you go. This is just how it worked for me. If you have any questions, Ill try to help you.

Хорошая альтернатива стандартным стиральным средствам — мыльные орехи. Это плоды индийского дерева, которые имеют моющие и противогрибковыми характеристиками. В отличии от обычных стиральных порошков, орехи экологически чистые для здоровья и не вызывают аллергии. Мыльные орехи используется для уборки в доме, стирки, мытья посуды, а также чистки украшений. Лучше ознакомиться с товаром и купить его, можно зайдя в интернет-магазин натуральных товаров для красоты и здоровья. CHANDI интернет магазин косметики. Мыльные орехи.
