[Q] I'm having trouble trying to unlock my HTC Mozart - Windows Phone 7 Q&A, Help & Troubleshooting

Hello,
I'm trying to unlock my HTC Mozart (OS Version 7.0.7004.0)
I'm using Chevron WP7 (not the official unlock, but the first one) but everytime I try to unlock it I get this message:
Sorry, I'm having trouble communicating with the phone.
-Please make sure it's connected using USB
-Please start the Zune application
I've already:
- Installed the Windows Phone SDK
- Sent the ChevronWP7 certificate on the phone
I tried a lot of solutions:
- Downgrade to Zune 4.7
- Downgrade to the previous SDK
- Add this registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsPhone\ProxyPorts]
“DeviceReg”=dword:000069C5
- Connect through WPConnect.exe
- Remove entries from HOSTS file
- Check that HOSTS file is not read-only
- Check the relationship with Zune
- Make sure that the device was not PIN-Locked and was on the home screen
I'm on Windows 7 x64, how can I make it work?
I can't use a cooked ROM because for an unknow reason, when I flash a cooked ROM, touchscreen starts to work bad...

Chevron certificate is out to date (since Nov,2011)...you have to change date settings on your device and pc (put the same i.e. 01/09/2011) - not connected to internet, both - and all should work well...good luck

THANK YOU SOOO MUCH!
IT WORKED PERFECTLY!
Thanks again!

glad for you, i remember first time i unlocked my phone, was so excited! i didn't slept during 24hrs looking for things to do...then i found XDA community !!! since that day there are always things to do... :]
Please change [Q] for [solved] in #1 post "edit post" then "go advanced"...thanks
If i can suggest you another "custom way" as you had bad issues untill now, let's give a try to ansar's new tech rom, it's quite a stock rom with awesome tools to update and keep unlock...

hallo... i have a Htc mozart too... and i try all of this that you said but i still get the same answer....
Sorry, I'm having trouble communicating with the phone.
-Please make sure it's connected using USB
-Please start the Zune application
what can i do..?

Where can I get the original Chevron WP7 Unlock and certificate?

With a time machine. They don't work anymore. The cert has expired and the hack that the tool used doesn't work on any ROM version since 7389 (which was released over a year ago).

what can I do now to jailbreak my htc Mozart...?

HELP ??
The instructions you can find here are all pretty clear and they work.
I went according to this one:
1. Install WP7 sdk Windows Phone Developer Tools;
2. Install zune;
3. Make partneship with zune and phone;
4. Attach the ChevronWP7.cer(you found in the toolkit) to your email and send the email to your email itself (On PC);
5. Login to your email account (On Phone), Open the email, Select attachment and install the cert;
6. Connect your phone to pc and make sure zune is running in background;
7. Run the unlocker (ChevronWP7.exe) and click unlock button(Make sure your phone date is set correctly)
(you need to close skype and disable network adapter.. hamachi.. wireless.. Dropbox.. etc)
6. Install toms .xap installer;
7. Deploy Connection Setup.xap, Touch Xplorer.xap and XBMODDeployer.xap (Install it on the phone and run XBMODDeployer.xap);
8. Copy the .provxml from the ringtons folder to the windows folder (on the phone using touch explorer app);
9. Run connection setup to install the .provxml;1. Install WP7 sdk Windows Phone Developer Tools;
2. Install zune;
3. Make partneship with zune and phone;
4. Attach the ChevronWP7.cer(you found in the toolkit) to your email and send the email to your email itself (On PC);
5. Login to your email account (On Phone), Open the email, Select attachment and install the cert;
6. Connect your phone to pc and make sure zune is running in background;

8. Copy the .provxml from the ringtons folder to the windows folder (on the phone using touch explorer app);
9. Run connection setup to install the .provxml;
You are probably just missing a step
you must be doing something wrong ..cause as i just stated above all the tool and unlocker still works as it did 3 months ago...check some of tutorials in the forum...

hi , i connected my phone using wpconnect , im still having same problem
Check your hosts file.
If it contains following entry, Chevron will not work:
127.0.0.1 developerservices.windowsphone.com
I cant remember where I read this but it helped.After completing the above instructions,Open task manager(Ctrl ,Alt &del).Go to processes ,select zune launcher and click on end process.reboot pc ,connect phone , wait for it to sync wit zune ,if it doesnt ,run zune then run chevron and you are done.I did this for 3 phones and it worked.hope this helps.good luck.
another confirmation that the unlocker still works for me without any problems at all...i dont nor havent deleted any host files or changed any setting at all within the machine. I have had one or two problems with it not working, the first problem i ever had when i first started using the unlocker was the registry key not being edited correctly... and for the second time it didnt work, all i did was unplug device and let re sync...tick, tick BOOM unlocked!! Besides those couple times it has always worked for me...Bought a new machine today and installed tools, then zune software and created account " naming phone " and installed chevron, opened and unlocked....if you have sdk tools installed and have the unlocker installed, with zune software completely set up and phone communicating with zune, not as guest...and you will change the relationship from guest to " whatever you name your phone " during setup... haven a complete and main relationship with phone " not guest " is one of the most important parts with zune!!! The other most important part is making sure the registry is edited and should look like this...
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsPhone\ProxyPorts]
“DeviceReg”=dword:000069C5
the window phone developer tools will edit reg for you...i have learned that if you relock the phone it sometime can takes a little while for things to click and be able to unlock again!!
So there is nothing wrong with any of the tools or unlocker, so if your having problems tripple check your zune settings to accomplish a non guest relationship, and check your reg. edit.....most problems i have seen and heard about are ppl and their zune!

how do you ensure that it is not GUEST?
i seem to be unable to get it to sync with ZUNE
Wow... you can come and work on our helpdesk any time, they log calls about as badly as you explain a problem lol.
You've said it's "not working". Why isn't it working? Where are you getting up to? Are you getting an error message?
Have you deleted all entries of Developerservices... from your host file?
make sure you have corrected date and time
and if possible use SIM Card with "big operator" in your country (well known operator)
sorry for bad english, using google translate

[Q] Hd7 Tiling changes?

Hello, I'm relatively new to the wp7 platform and am wondering if there's a way to change the tile colors to something other than the ones that are set? I'm new to all of the phone editing world as well, so sorry if this seems like a 'noobish' question. Thanks
You need to have an unlocked device & side load the app, Accent Changer.
Thank you!
How do I go about unlocking my phone??
Does your device have the NoDo update? If so you either need to sign up for a student apphub account to legally unlock your device or downgrade to a pre-NoDo ROM & unlock via a hack like Chevron Unlocker. There's a few threads around XDA about this.
See these;
NODO jailbreaking,100% sure
ChevronWP7 Unlocker & Cert download
You'll also need a side loader app such as;
TouchExperience WPDM public release
I'm at OS Version 7.0.7390.0. I believe that's the NoDo update, right? Do I use the first link to unlock it then??

Correct, that is NoDo. The firt thread I posted shows a way to hack unlock by downgrading or else try this (How to register/developer Unlock Windows Phone 7 for free, even NoDo) thread which I used to unlock mine.
I'm not a student, so I don't have a student email ending in .edu. How do I downgrade? Thank you for all the help and everything by the way!
Find the Forum for your specific device & there should be a ROM for it you can download & flash. Remember, you'll have to reinstall all your apps, contacts, settings, etc.
I did the zune restore. I'm back to version .7008. Do I just follow both of the links you previously posted now?
Use this one, you'll need the ChevronWP7 Unlocker & Cert to complete the steps.
EDIT: Intsructions for the Unlocker Tool found here.
When I go to open the Chevron thing, I get an error message, that it can't find my phone or soemthing. That's not normal, is it?
No clue, I never used it. I can tell you, make sure you emailed yourself the cert & download & install it from you cell's hotmail. Also, make sure Zune is open.
At the unlocker & cert link, how do I do step 5?

Registry Editor
You'll need to side load it with Tom XAP Installer v1.2
I also recommend side loading Advanced Configuration Tool to enable Max Side Loaded apps.
Also make sure the Dev tools are installed...
What Dev tools??
I dont know what I'm doing wrong. I keep getting the message saying it can't communicate with my phone. :/
Oh, I think this is the WP7 Dev Tools FiyaFleye was talking about.
EDIT: Also, make sure your cell is not asleep or locked. See this video;
http://www.youtube.com/watch?v=3ozyq-PMD7g&feature=player_embedded
EDIT2: Just realized, that reg should be on your PC, not cell, duh. Open Start Menu, click on RUN, type in "regedit" without quotes. Click ok or hit enter key. Registry editor will open. Browse registry to the specified value in step 5. From what I read, this value should be added by the Dev tools, or you can manually add it. Once you successfully unlock your device, make sure to go to the how to thread & follow thesteps to prevent MS from relocking your device.
So the dev tools won't work if I have windows xp? That's unfortunate

Okay, I've changed the registry, and i re-downloaded the ChevronWP7 file, but I'm still getting the error message that says "Can't communicate with phone, please make sure phone is connected via USB - Please make sure Zune is running." when I try to open the file.
Could this be happening because I was running the NoDo update previously?

Depends, what phone?
HTC HD7. Everything would be ok and I could use to new design, but none of games isnt working - MS Revoked
Developer-unlocking a Mango phone (dev-unlock is what ChevronWP7 Unlocker did) is possible with an official marketplace developer account, or (soon) through ChevronWP7 Labs. If you have a restore point for NoDo, there are ways to carry the unlock forward if you don't have an official one (although for HTC it's more difficult than for Samsung or LG, and the methods keep getting closed off).
"Application has been revoked by Microsoft" message usually means that you're trying to run a sideloaded app on a non-dev-unlocked phone. This can be fixed by dev-unlocking. Now, I'm going to avoid jumping to any conclusions, but there aren't that many games publicly available for sideloading. XDA-Developers is about using our phones without artificial restrictions, not about using other people's work without paying for it. Discussion of software piracy is not accepted here. Just... thought you should know.
I restored my phone back to nodo with backup. Maybe will try to update with unlock someday.
ps. maybe someone can tell me privately how to reinstall (install android) if there is no exe files but only system files in extracted folder ?

[Q] INTEROP-UNLOCK for MANGO - No revert to NoDo - is it possible for HTC devices?

Hi there, I've read several guides and tutorials around how to allow InteropServices on Mango (beta2) devices by changing MaxUnsignedApp value, but so far there was no working solution for HTC devices, only Samsung ang LG(?).
So does anybody know how to enable interop services on HTC device running Mango Beta 2 and regular Dev unlock? I really don't want to revert to NoDo once Mango RTM is available in Zune.
Thanks in advance!

If you continue reading, you should have read that there is no way yet, but its still being figured out. Hopefully real soon.
If you are already unlocked, have TouchXplorer already Sideloaded, USB Storage Enabler install on your PC, & HTC Connection Setup, than you can do this registry hack with CustClear.ProvXML. Create the ProvXML, copy it into \Windows\ of your device & run HTC Connection Setup. If you are own NoDo, I suggest installing Registry Editor & Advanced Configuration Tool by Schaps as he now has Mango compatible versions available.
It might be possible to patch a network selection app for everybody with an unlocked device.
You will download the app legally from the marketplace, than use heatcliffs method to replace a provsion file from one of the providers by deploying the app. This provision file now contains all the keys to unlock, run your legally downloaded network selection app, select the patched network and bam unlocked.
If somebody is willing to test I might give it a shot, PM me.

I tried TouchXplorer on my HTC HD7, but it won't work, because of InteropServices limitations - with the capabality in manifest it won't install, without it it installs, but does not work. I've tried several file system managers, ho success. I don't know, what is USB Storage Enabler, but if it's some kind of homemade USB jig I'm not interested.
Well, it looks like NoDo revert is the only way

This is why I said if you have TouchXplorer Sideloaded before Mango. Then, it'll work. I have TouchXplorer/Registry Editor (Mango Version)/Advanced Configuration Tool (Mango Version already Sideloaded & waiting for official update to come through so I'll be ready. My only concern is I might need to use the unlock hack when i update to Mango even though I have an official AppHub account. When I tried upgrading to the Beta & RTM, the unlock tool wouldn't connect due to apps/registry changes I have installed.
If that is the case does that mean screen capture app based on dll will work?

So I rolled back to NoDo today, dev unlocked, installed TouchXplorer, Advanced config. and DiagProvXML, uploaded CustClear.provxml file to Windows file and runned Connection setup... but after updating to final Mango nothing works, all three apps are not working, so I guess it's no go for me with interop services.
This is an absolute no-go. Of course I tried this, but Interop-dependent apps installed before the update didn't launch after the update. Interop-dependent apps in Mango won't install. With the capability commented out they install, but don't work. Especially TouchXPlorer, which does not show any files, Registry Editor seems to be working, but cannot acces the right keys (same as on NoDo), Advanced Config works, but does not actually apply the settings. I also wasn't able to make any of the ProvXML deployers work.
ProvXML I prepared to the Windows folder was not applied by Connection setup (however this method NEVER worked for me before Mango, I'm actually quite surprised, I've been that dumm to try it).
Heatcliff says he's working on HTC-compatible Root Tools, so let's just wait for it

How to tell my phone is unlocked or not

I've just bought a second-hand Samsung Focus (SGH-i917) from a local cellphone vendor for developement purpose. From settings, about, it reports software version Windows Phone 7.5 and OS version 7.10.7720.68. Is there a way to find out if my phone is unlocked or not. If unlocked, how can I load XAP onto the phone? If locked, how can I unlock it. BTW, I do not pirate, just for developement.
Hi
You can see if your phone is locked or not trying to deploy a XAP file on it.
You can do this using a deployer like Tom XAP Installer.
You also need the Windows Phone SDK (download it HERE) which is necessary to develop applications and deploy them.
After installed, download a XAP file (or use your own), connect your phone and run WPConnect (C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Tools\WPConnect) and open Tom XAP Installer, select Add XAP files and click on Install. If the installations finishes correctly, your phone is unlocked, otherwise you have to unlock it.
You have two ways to do this:
- Official jailbreak by Microsoft (HERE), It costs 9$ and allows you to deploy 10 applications. You won't lose warranty.
- Downgrade to the 7004 firmware (VIDEO) and unlock it using ChevronWP7 (Download HERE), then before updating to Mango you have to send a file (unlock.xml) to your phone (Tutorial Here), otherwise you'll lose the unlock.
Thanks, I'll try your instructions.
@AshleyT: A couple of minor corrections:
The official ChevronWP7 Labs unlock is not by MS, though they permit it (thus "official"). They don't get the $9, though you do have to use a Live ID.
There is another official way to dev-unlock your phone: get a Marketplace developer ("AppHub") account. http://create.msdn.com ($99, goes to MS) or http://dreamspark.com (requires student email address, free). For these methods, use the Windows Phone Developer Registration tool that comes with the SDK download.
The reason I point out the apphub account option is that, if the OP wants to develop apps, he or she may want to publish them to the marketplace at some point. You can't do that with a ChevronWP7 unlock, official or otherwise, but you can with AppHub.
Chevron can check whether your phone is unlocked, or u can try to install one simple xap application to test this.
It seems that my phone is locked.
First I tried Tom XAP installer, it said:
-Please Make sure your phone was unlocked!
-Please Make sure you connected device to PC and Zune launched
Try again?
Then I tried Application deployment from Windows Phone SDK 7.1, which said
Error - Failed to connect to device as it is pin locked.
I am sure my phone is connected to PC as I can see music/video/picture in Zune.
Could someone explain to me what is "pin locked"?

To remove the error of pin locked u just need to swipe up the lockscreen and try to deploy the xap file.. it will be successfully deployed..
I countered the same problem earlier..
Hope this helps
i have successfully unlocked my Dell Venue Pro and i have 5 applications installed. Now when i do Hard reset I'd be able to install only 5 or 10 applications?¨
