I have the same problem, I tried everything, turn off firewall and antivirus, the registry trick, the actual wp7 SDK, airplane mode, date and time, host file, everything that this 56 page thread has to offer but no results. I even re-flashed WP7 all over again by flashing first an official rom then hardSPL and so on. I unistalled and installed everything in my computer but nothing. the only thing I cannot do is format my computer due to various reasons.

on the other hand, I read somewhere that Chevron is something like web based, I mean it works like internet connection sharing between pc and phone, thats why you need to be disconnected from internet. if thats the case, then I have to admit that my HD2 with WP7 when connected to Zune gets no internet, even in flight mode. I don't know if thats normal, I suppose not but thats what happends. no internet acces through Zune, maybe thats why chevron doesn't work... I had to set an wireless point to get internet access and download the e-mail with the cert in my HD2...

I suppose that at the moment ther is no other way to unlock the phone, right?

If you have any other ideas, please tell me.

thanks

WORKED AFTER FORMAT!!!!

imho it's a windows update!
[Windows Phone 7 Development and Hacking] armato:
like you i tried everything but nothing...

i just formatted... install zune and sdk and all works perfectly now...

imho we need to block automatic windows update... the last one remove the possibility to use chevron... always always imho

edit: now i try to update windows except updates of 2011... i ll see and post results
[Windows Phone 7 Development and Hacking] Pica_Man:
Chevron has just stopped working for me after no previous problems at all. I have not installed any updates.

EDIT: i'm on Win7, got SDK installed. worked yesterday and doesn't today. I think chevron is accessing my Wi-Fi internet connection when i run it- why?
[Windows Phone 7 Development and Hacking] Pica_Man:
Found a fix, this worked for me:

6. navigate to c:\windows\system32\drivers\etc\ then opem hosts with notepad 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

Attention: if port 443 is used (see on your list) stop IIS or exit Skype program
[Windows Phone 7 Development and Hacking] jardan:
I tried that too, because of the 7th step I tried to see if I actually have access to internet with my phone when connected to Zune but as Isaid I have no access, maybe my problem is somewhere there...

the rest of you that are unable to use ChevronWP7, do you have internet access on your phone when connected to Zune?
[Windows Phone 7 Development and Hacking] Verkunder:
I get the feeling we're all shooting in the dark trying to get this thing to work. I get the feeling the only solution will be the have the Chevron people actually find a fix, but since it'll be disabled in about a month...
[Windows Phone 7 Development and Hacking] Donagh:
Have tried everything on this thread and the others and still can't get it unlocked.

Yeah, still have internet access.
[Windows Phone 7 Development and Hacking] Diggia:
@Pica_Man

Great suggestion, i "navigate to c:\windows\system32\drivers\etc\ then opem hosts with notepad and delete any references to windowsphone developer services" as you told us. So i tried with ChewronWP and now i have finally unlocked my device again !!!!

But now i have problem with XAP installer, i get "connection error". Any ideas ?
[Windows Phone 7 Development and Hacking] becknise:
Finally unlock

After 24 hours of trying to unlock i finally managed to do it. A long process and painful unfortunately. I formated my hard drive, install a new windows os and reinstall all tools and zune.
[Windows Phone 7 Development and Hacking] X2xc:
Thanks man.

Great work, working for me
[Windows Phone 7 Development and Hacking] darkduelist:
Thanks bro !!!!! work for me too.
[Windows Phone 7 Development and Hacking] Freek666:
Works not for me.

I had everything working but Zune updated my phone to 7004 and

disabled al the programs i installed via application development.

By example when i start TouchXplorer i get the message: TouchXplorer has been revoked by Microsoft. Please uninstall it. [uninstall] .

Chevron: Sorry, I'm having troubles..

Weeh.. ;-)
[Windows Phone 7 Development and Hacking] Pica_Man:
The Chevron guys are apparently now developing for microsoft, they won;t be updating their software in any way :(
[Windows Phone 7 Development and Hacking] Verkunder:
That's exactly what I'm saying.
[Windows Phone 7 Development and Hacking] Pica_Man:
As @Verkunder says, we may all just be shooting in the dark here, trying different things and sometimes getting lucky. I'm certainly no expert.

anyway.....

I guess u r using Tom's XAP deploy, try using the deploy application in the Developers SDK, or if you search on the forum there are some other apps around as well. I had probs with Tom's a few times as well. good luck.
[Windows Phone 7 Development and Hacking] Pica_Man:
Thats happened because the phone re-locked itself (i think the zune desktop does it). So unlock it, deploy your XAPs, then unplug your USB and then do what you need to do with the XAPs. There is a Registry edit that will stop the phone re-locking, its on the forum somewhere, but don't ask me where! :rolleyes:
[Windows Phone 7 Development and Hacking] dinkk007:
Thank You.... So much.. I searched everywhere and was unsuccessful no matter what I tried... This was the only method that worked.

Thanks Again
[Windows Phone 7 Development and Hacking] b16b:
i can even now unlock my phone hd2 but i can't use xap anymore... maybe new zune block the xap? anyone who using xap right now?
[Windows Phone 7 Development and Hacking] kata:
Also for me.

This method is the only one that works. :-)

Thanks
[Windows Phone 7 Development and Hacking] Laurentius26:
@Iridium21 and Cendaryn, thank you.

Working like a charm, unlocked my HD2 :)
[Windows Phone 7 Development and Hacking] js1974:
It's absolutely amazing how much trouble I had getting the ChevronWP7.exe working. I was suffering like many other people so I broke it down piece by piece and for me I was able to get this issue resolved following these steps.

1. Go to the Control Panel

2. Devices and Printers

3. Select your Windows Phone

4. Right click and choose Troubleshoot

5. The troubleshooting program ran and found that the driver while it was connecting was not connecting properly.

6. Choose fix - It should say unknown device driver fix.

7. Close Zune and reopen Zune

8. Wait for the sync information to show up.

9. Run chevronwp7.exe

10. Profit

I really hope this helps some of you I can't believe how easy it was and I spent so much time trying to get this resolved.

Other steps, Make sure in Services.msc Zune Windows Mobile Connectivity Service is started and manual. You can also try to restart it.
[Windows Phone 7 Development and Hacking] Verkunder:
No dice. I think I'm officially giving up getting this thing to work.
[Windows Phone 7 Development and Hacking] DanielNTX:
No go, here either. The phone re-locks itself and I've tried it on: three Windows 7 (x64) machines and two Windows 7 (x86) machines and it's a no go. It's the program. It knows when the phone is pin locked so it is connected. I think the error message is ambiguous and not representative of what the real error is. I think it won't unlock because the HTTPS server it's trying to spoof is not responding.
[Windows Phone 7 Development and Hacking] djyl:
wp7 chevron

hello i have unlock my phone greatfully, but now i have microsoft message of my phone omnia 7:

[Windows Phone 7 Development and Hacking] ceesheim:

[Windows Phone 7 Development and Hacking] kreedz92:
who can make for me a video like "how to hack wp7?" i'm hungarian and my english not too bad and not good... :S

thanks a lot!
[Windows Phone 7 Development and Hacking] Jaxbot:
Here's one I made: http://windowsphonehacker.com/tutor...ice_and_install_custom_ringtones-12-01-10.php

Uninstall it, and then re-unlock your device. The certificate was probably deleted somehow.
[Windows Phone 7 Development and Hacking] Shudog:
Hi guys,

I am having a problem with this.

I followed all the steps int he video tutorial, but when i run it, i tick the two boxes, and as soon as i click unlock, it errors out straight away. (chevronwp7 has stopped running)

I am using Windows 7 Ultimate, and a samsung omnia 7.
[Windows Phone 7 Development and Hacking] lekki:
So I name the file DeviceReg and save it as a txt. I changed it to .reg and ran it but got the error saying it wasn't a registry script.
[Windows Phone 7 Development and Hacking] iridium21:
Excellent! Added to first post. Thanks.
[Windows Phone 7 Development and Hacking] feygor:
didn't use this when it was first out, i was gutted when it was discontinued and the custom ringtone xap was created. Just tried it, not a single error, already had developer tools, i just mailed myself the certificate then ran the program.

Thanks loads
[Windows Phone 7 Development and Hacking] prootc1:
hello,

i´m trying to do this unlock, but don´t now how to modify the reg, in my regedit, dont have that...

any help?
[Windows Phone 7 Development and Hacking] heisven:
Try a real SEARCH for it. Not just open directories.
[Windows Phone 7 Development and Hacking] prootc1:
already try, but maybe wrong name, what name i search?

Dont appear nothing on "DeviceReg"...
[Windows Phone 7 Development and Hacking] prootc1:
Now Mine show this, cant get access at proxypots...

Regards
[Windows Phone 7 Development and Hacking] Snppls:
Thank you for this. It's insane that they are charging developers $99 to be allowed to develop apps for a platform that desperately needs more apps. Why no free accounts that allow development, debugging and testing and a paid account that allows shipping to the marketplace.

I'd like to use this just to debug my apps on an actual phone, I don't want trouble with microsoft or lose the ability to use the marketplace or something like that. ChevronWP7 says it's easy to revert the changes to the phone and relock it completely, but I'm not seeing that option anywhere on the program and nowhere is it mentioned how to do this.

Anyone know how remove the certificate again?
[Windows Phone 7 Development and Hacking] Foxandxss:
As I said in another post:

That resolves the "crash" problem too.
[Windows Phone 7 Development and Hacking] abudabu:
Gah!! Tried everything mentioned in this thread.

Even the hosts file, I made sure Read Only was unchecked. Tried on my computer (XP SP3), 3 different cables. Nothing is working on my phone - Samsung Focus

Steps I did:

Installed cert. Synced with Zune. Signed in to Zune. With Zune open and phone on start screen, I opened ChevronWP7 tool. Checked both checkboxes and clicked [Unlock]. Damn error message

**can't post link till I reach 8 messages**

I've hacked into iPhones and Androids. But this is, by far, the toughest.

Does everyone's Registry show similar to mine:

**can't post link till I reach 8 messages**
[Windows Phone 7 Development and Hacking] .oisyn:
I initially had the same problems. Make sure the Zune software isn't actually syncing stuff. Once, Zune kept saying it was at 0% of the syncing process (even though everything was up to date). Reconnecting the cable helped solve this.

FWIW, I'm using Windows 7 x64
[Windows Phone 7 Development and Hacking] taz5176:
i saw the tutorial vid at 1.25 mark, the unlock button becomes relock, i saw somewhere someone saying to use the chevronwp7 to relock the phone as well.

but yet to see anyone posts on that.

btw, is there any way to tell if the phone is unlock? i mean from the phone itself?

EDIT:

by reseting the phone, does it relock?
[Windows Phone 7 Development and Hacking] TehPenguin:
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)
[Windows Phone 7 Development and Hacking] orb3000:
Hey TehPenguin!

Nice to see you around:)
[Windows Phone 7 Development and Hacking] EclipseX:
hi, I have a big probleme here...I try all ways...and not working :S

I'm connect to zune but....when I try run ChevronWP7 I check all boxes and click on unlock....when I try click unlock the cheveronWP7 give me the message Please make sure.....please start zune app....

Omg I don't know whats happens....:S

ps: I have 2 keys for windows phone....I call to microsoft for ask about that....and the keys don't work :S
[Windows Phone 7 Development and Hacking] jardan:
so guys this is what I did. after trying everything mentioned in this and other fora I was always getting the no connection error. while I was going to give up, I had my phone connected to zune and also connected to the internet I decided to synch my mail, after sync was done I tried one last time ChevronWP7 and this time it worked! and because I mess the never-lock hack, I hard reset my phone, did the same thing again and worked again!

just do not press relock as I did and you will not have to hard reset..

I hope it works for you
[Windows Phone 7 Development and Hacking] Drakosha:
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 :)
[Windows Phone 7 Development and Hacking] Shadowsalyer:
Too bad, even that won't work for me, did you list even the most obvious steps?
[Windows Phone 7 Development and Hacking] lemonspeakers:
I'm still not being able to get this working! I still have the "uh.Oh!" message!

zune connects fine and can sync. but chevron cant recognize the connection! WTF!

anyone else?
[Windows Phone 7 Development and Hacking] tauntt:
App was working, now it's not. I get this: I'm sorry can't communicate with phone. Zune is launched, and see's my phone. What might be the culprit?
[Windows Phone 7 Development and Hacking] aPlekan:
im haveing a problem with my phone randomly reboting. also when i soft power my phone and go to turn in on in like 5 min or so i get nothing. just a balck screen. the only way to get it back is to pull the batt out and restart it. has anyone els have this crashing problem? i really need my help please!!
[Windows Phone 7 Development and Hacking] doublecheese:
I have unlocked my HD7 when the Chevron was first announced to public.

Since then, I have never had this UH..OH MESSAGE ............ , I have also installed TouchXplorer but I did not install any customs ringtones.

When does this message pop up, on the screen of the WP7 phone ?

Everybody is having a problem and how come I am not having one ?

My HD7 is a phone I bought from UK with O2 Pay As You Go line and then I have it unbranded it and now I use it as an unbranded phone with a few different sims.
[Windows Phone 7 Development and Hacking] EclipseX:
I've benn sucessefull in unlock my phone....ChevronWp7 say unlock....but When I try install any app

see that:

Zune is open, no firewall no nothing turn on...only zune :S

wtf?!
[Windows Phone 7 Development and Hacking] mikmik111:
I don't know if this was said before but the only way for me to unlock it once again is to reset the phone. Settings->about->reset your phone.

Make sure you back up first and/or there's no important file that you need that's in the phone. I don't because most of the services are cloud based.

And make sure you unlock it this time with the ChevronWP7 no sideload limit, and then patch the no relock registry as soon as you unlocked the device without even disconnecting it from your PC.
[Windows Phone 7 Development and Hacking] krumbs:
Struggled with it for two days, tried almost all suggestions, used three computers. No luck. Finally what worked (tried it two times in a row) was having Windows phone emulator running in the background. Detailed steps:

Reset the phone (from Settings - About)

Let Zune recognise it, sync it up.

Add a gmail account (any non-Windows Live account), mail yourself the certificate, open, install it.

Put the phone in airplane mode, start ChevronWP7. Do not tick the checkboxes or the unlock button.

Start Windows Phone Emulator. Wait till it loads with the IE logo. Do nothing more with it.

Return to Chevron, run unlock.

Pray it works!
[Windows Phone 7 Development and Hacking] theshowman:
Wow, nice. It finally worked for me with your trick, after having exhausted all other instructions (kept on getting the connection error from Chevron)

Brilliant and many thanks to everyone else for their efforts.
[Windows Phone 7 Development and Hacking] eiMer:
Hi,

finally i read every single post in this thread and my HD2 is still locked. (no connection prob.)

A few days ago i unlocked it without any error. Yesterday i tried to install a ringtone.xap but the installer said that the phone is locked -> pleas unlock!

So i started Chevron and the only option was RELOCK!! So is thought - no problem.. fist Relock, then Unlock it again. But i think that was a big mistake.

However, is it possible to Unlock the device after u hit the Relock button??

Thank you for ur help!!
[Windows Phone 7 Development and Hacking] lionhart1001987:
hi , i tried this method but i couldnt download window phone emulator due to my country.

any other way ?

as long as i click unlock , my program stops working and closes
[Windows Phone 7 Development and Hacking] krumbs:
Did you try a full reset? For me, that helped things a lot. I know, it is painful to start all over again, but might be worth a shot (assuming everything else has failed).
[Windows Phone 7 Development and Hacking] eiMer:
windows\system32\driver\etc -> set "hosts" file to NOT read-only
[Windows Phone 7 Development and Hacking] eiMer:
No not yet... but i think this is the only thing left to try.

Ill do this tonight and post my results.

Has anyone hit the Relock button und Unlocked it again?
[Windows Phone 7 Development and Hacking] krumbs:
The program crashes could be because the Hosts file is read-only. Please check its properties, also open in Notepad and delete all references to localhost/ your ip which Chevron might have added.

Am not sure if the package is available as a redistributable. It comes with a small installer that downloads around 350mb data.

Would you be able to do a VPN to a US IP and then download the package?

Or maybe someone smarter would be able to upload just the emulator for everyone to download - am sure we don't need the entire package to make this work.
[Windows Phone 7 Development and Hacking] lionhart1001987:
okay , im not sure how to dele all reference to localhost / my ip which added

another qns

it says im having problem communicating with the phone

please make sure its connected with usb(obviously)

please start zune application(it started when i plug in the phone)

how ?
[Windows Phone 7 Development and Hacking] EclipseX:
my probleme is solve for now =)

I only reinstall all app of my pc...

framework + sdk + windows phone developer tools
[Windows Phone 7 Development and Hacking] Frasch:
Find your "host" file drag it to the desktop. Then right-click open with notepad, scroll all the way to the bottom, delete anything with windowsphone. Click file "save" then drag the file back to its original folder.

That will fix your next set of questions as well...:cool:
[Windows Phone 7 Development and Hacking] lionhart1001987:
hi , tried it .

no avail.

im going nuts , ive been trying all solution and im still stuck here.

OMG !!@@$#!%R!@$#!@#

it still cant work ):

did the drag , did the delete my ip address , still cant
[Windows Phone 7 Development and Hacking] dexcox:
this one worked , thx a bunch !!!!
[Windows Phone 7 Development and Hacking] Mallux:
The first time i tried to unlock, it took me forever. At first, when i would try to open the launcher, i'd get the "oops" message without ever seeing the launch screen. Then, after hours of trying random things to fix the issue, it suddenly opened and i was able to check the two boxes and press launch; however, it still produced an "oops" message. About thirty minutes went by as i kept trying random things, before I just said f*@k it. Then suddenly, after just sitting there for about ten minutes, i tried it one more time and it worked...

Now that the new accent changer has come out, i tried to install it and for some reason my phone was relocked...So, i tried to use the unlocker again and..."oops". So, i've gone through all the steps again and i've gone back and forth between "oops" while launching Chevron and "oops" while attempting to unlock and it really doesn't seem like there's any rhyme or reason to this error process. At least not that anyone is aware of. It seems more like people are trying random things and when the unlocker suddenly works, they attribute its success to whatever steps they recently took.

Not to be a jerk to those who've posted solutions, I am truly thankful that there are people out there who are willing to help out with the issues many seem to be having. It just doesn't seem like the true issue has been brought to light yet.
[Windows Phone 7 Development and Hacking] Mallux:
all that is inside my "hosts" file is:

192.168.1.102	developerservices.windowsphone.com

127.0.0.1	developerservices.windowsphone.com

192.168.1.101	developerservices.windowsphone.com

Am i supposed to delete everything?
[Windows Phone 7 Development and Hacking] eiMer:
Thats absolutely correct!

Almost none of these random changes make any sense. The first time i unlocked my HD2 i dident even open the hosts file to change anything. I just set it to not read-only.

There must be a solution for this issue but until now no one figured out what exactly has to be changed.
