[Windows Phone 7 Development and Hacking] RustyGrom:
So I've been banging my head against this for a few hours and not getting anywhere really. I modified the HTC XAP in the OP with a different setting just to see if I could get it to write to the registry at all, even in the white listed locations. But it's a no go on my Titan. Shouldn't this work?

<wap-provisioningdoc>

<characteristic type="Registry">

<characteristic type="HKLM\ControlPanel\Phone">

<parm name="test1" value="test1" datatype="string" />

</characteristic>

</characteristic>

</wap-provisioningdoc>

I'm not having any luck whatsoever getting the ConnectionSetting trick to work at all. It says it applied the settings but my registry value isn't getting created. Am I missing something? I know the files are getting copied because the Interop Unlock entry is getting added (I've used the reset thing to make sure it's not just using an old one).

Any update on 2nd Gen HTC devices?
[Windows Phone 7 Development and Hacking] Jznwlnl:
@Heathcliff

I have WP7 Root tools running. I also tried to fix my 3G connection with your xap file and with step 11.2 unfortunately both are not working?
[Windows Phone 7 Development and Hacking] Heathcliff74:
I will now cast a magic spell to get rid of the error messages you're seeing. Is that "working"?

[Windows Phone 7 Development and Hacking] Jznwlnl:
I will try to explain it better than last time.

I have deploy you xap file to fix the 3G connection to my phone. Unfortunately if I turn my 3G connection on "3G" doesn't appear. So I tried step 11.2 and here I get the same result: no "3G" at the top of my phone.
[Windows Phone 7 Development and Hacking] Heathcliff74:
That's a little bit better already...

What Device brand/model/OS version/Firmware version do you have?

Did you try all other recovery options? What was the result of that?

Are 2nd Gen Samsung devices still a possibility for Interop unlock with this method yet?

thanks for all your work!
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Samsung gen2 devices can be interop-unlocked with this method. However, so far we haven't gotten any interop apps to work on them, so the only benefit of interop-unlock right now is to install additional homebrew apps.
[Windows Phone 7 Development and Hacking] jaminroe:
Doesn't work on mine I guess

So if I have all the latest updates on my HTC HD7, I can't Interop yet correct? Just double checking... Because I followed all your directions, and everything went well. But when I try to install something like TouchXperience or Registry Editor, it gives me the error of not being able to install an Interop application.

I will keep an eye out for an update. Fingers crossed ;)
[Windows Phone 7 Development and Hacking] Klocker2:
thank you yes

Focus S and did Chevron and the tethering/interop unlock and can load interop programs and run some like advance config tools 1.5 beta but few if any features will make changes.

so hopefully, 2nd gen can get registry allowed some day. :D

That's right!

Fingers crossed you get Interop for updated HTC Mango Devices working ;)

Hello,

I must come back to this problem because I've just discovered that the 0x89731812 error is back to another my computer.

As I sayd about one week ago I solved this problem with a hard reset of the mobile. But on a new computer that until few days ago the xap deploy worked properly, now stops with the same error.

On the other computer the xap deploy is continuing to work without any problem. That's quite strange...

What do you think Heathcliff74 ?
[Windows Phone 7 Development and Hacking] Ttblondey:
Are the name of your pc the same?
[Windows Phone 7 Development and Hacking] Sig. Gargiulo:
No, is different like the others that the deploy works properly.

Wanted to ask the same thing..

Any progress ???
[Windows Phone 7 Development and Hacking] e_rl:
I wish somebody would make an unlock that didn't require an unlock previously. Chevron doesn't offer tokens anymore and the other option doesn't work for VZW Trophy.

:(
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Well, that's what the Windowbreak project is all about. Sadly, it requires using known file types, and the HTC interop unlock uses a file type the phone doesn't (officially) open.

You can always get a developer (apphub) account, which will let you unlock your phone. It does cost money, though, unless you're a student. Students get free accounts through Dreamspark.
[Windows Phone 7 Development and Hacking] reflaze:
whats the actual state of the interop for htc devices? There are many threads and people write about different versions. (v2 v3)?

Can I use the latest version to interop my 7740 HD7? And Which is the latest version? sorry but I lost the overview....:confused: :D

Hello,

I have HTC Trophy with Mango 7740.16 and unblocked with Chevron from Nodo Chevron, the unfreezing goes perfectly I can implimentar apps and they work correctly, except someone of photographic type that at the time of taking the photos of the gallery gives to me "nullreferenceexception". My question is; is this a question of interop, and if I try to install Interop.xap he might interfere with Chevron?

Thank you in advance a cordial greeting.
[Windows Phone 7 Development and Hacking] Bator92:
But with this I can install only three apps. How can I install more apps? (HTC Trophy 7740, newest drivers)
[Windows Phone 7 Development and Hacking] dragonide:
We are on the same boat, we are all waiting for interop unlock of second gen devices :/
[Windows Phone 7 Development and Hacking] JuvenTino.ks:
So this is how I unlocked my Verizon Trophy running MANGO (this is the only way I was able to get 3G to work after the unlock)

1. install the htc connection app from the market

2. deploy the HTC interop unlock app

3. make sure there is a SIM card in your phone

4. go to settings>cellular>GSM

5. look at the status bar on the top (keep your finger on it) in the second the network status changes to the bars with the circle in them, start the htc connection app.

6. click the 3 dots down to the left, chose manual, in the country choose interop unlock

7. hit the check thingy on the button

8. restart your phone

9. VERY IMPORTANT UNINSTALL THE HTC CONNECTION APP

10. change the network settings back to CDMA

11. you're done.
[Windows Phone 7 Development and Hacking] reflaze:
What about an interoped unlock for the 1st gen htc devices with 7740 and htc updates?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
@reflaze: We're working on it, but it's likely that anything which works will also work on HTC gen2. Since gen1 can downgrade the driver and gen2 can't, just keep an eye open for gen2 news. We are trying.

In the mean time, if you really want interop-unlock, just downgrade your phone, use interop-unlock for HTC, and upgrade again.

i want to know my cellphone can keep interop-unlock when i upgrade to 7740

is there any backup tool for WP7?
[Windows Phone 7 Development and Hacking] snickler:
If you use the WP7 Cab Sender, you can send cabs to the device and make a backup of it. Either way, upgrading to 7740 and even to 8107 keps interop unlock =)
[Windows Phone 7 Development and Hacking] memeqxda:
where can i find the cab sender, and is it risky and complicated ??

so after i upgrade my phone to 7740, do i need to register my phone again ?
[Windows Phone 7 Development and Hacking] snickler:
Not complicated at all. If you head to Heathcliff74's thread with the CAB update list, you'll find instructions on how to apply those updates. Its in this same forum. No need to register your phone again either. All unlocks persist through these updates
[Windows Phone 7 Development and Hacking] farooq88:
yes ur cellphone can keep intropunlock after updating

and i know it cuz i updated my phone to 7740 and by the normal way via zune

does anyone know how to extract xap from phone ?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
What do you mean, extract xap from phone? XAPs are installation packages, once an app is installed the phone doesn't store the XAP.

There are some XAPs on the phone, system apps that are included with the ROM; you can retrieve them from the \Windows folder using the WebServer app, any filesystem explorer, or WPDM.
[Windows Phone 7 Development and Hacking] memeqxda:
i mean can i extract apps from my phone

WPDM seems not work on my computer
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Installed apps? Short answer: No.

Longer answer: Not without way more work than it's worth.

Obligatory question: why would you want to do this? I can understand wanting to back up the data for the apps, but what's the point in "backing up" the apps themselves? You can just re-install them (from marketplace or use a XAP deployer if homebrew).
[Windows Phone 7 Development and Hacking] nitin88g:
Hi,

I have developer unlocked Omnia W (Diagnosis app ver 1109)

I deployed the xap using Application deployment tool.

But when i open gprs save menu (Heathcliff v2 is not available).

How can i Interop-unlock my device!!!
[Windows Phone 7 Development and Hacking] memeqxda:
my connection setup version is 1.9 and this version seems not exist in marketplace or somewhere.

last time, i update this app, trying to interop unlock my phone; however i failed.

then, i restored my phone ,and use that version. successfully unlock my phone.

so im wondering if the app is the key to successful unlock. that's why i want to preserve the app

maybe few weeks later, new way of unlock phone will be released. the app is not that important
[Windows Phone 7 Development and Hacking] Nullstring:
I have not yet applied the HTC Interop Unlock. I just wanted to check MaxUnsignedApp in my registry and currently, the value is way far than 300

MaxUnsignedApp=2147483647

Should I still run HTC Interop Unlock?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
If your MaxUnsignedApp value is 2 billion and your phone is developer-unlocked, you are most certainly already interop-unlocked. In fact, you can't even read those values normally without being interop-unlocked.

At a guess, you may be using a custom ROM (these typically come pre-unlocked) or you may have used some other other technique which applies interop-unlock (but doesn't necessarily call it that) such as Ansar's upgrade/unlock tool.

VZW HTC Trophy Unlock Procedure

All - after some trial and error and keeping 3G after applying this to my VZW Trophy, here is the modified procedure I used that worked (note I did this even being on 8107 from pushing CAB updates). I only have the v1 HTC drivers so I expect v2 will not work. Note - read this before doing as you have to be fairly quick at one point.

1. Make sure you have a backup of your device (scroll up for instructions)

2. Make sure you have a backup of your backup (No kidding! Zune may overwrite the backup you made. Here's the backup: %LocalAppData%\Microsoft\Windows Phone Update)

3. Download this attachment to your PC: HTC Interop Unlock.xap

4. Connect your device to a PC running Zune and install the xap-file using any xap-deploy-tool. You don't need to start the app. If it starts automatically, you can close it right away.

5. Download and install HTC Connection Setup on your HTC device (if you don't have it already)

STOP - go to Settings>Cellular and set Mode to GSM. Exit back to main screen and wait for data connection to go away (there will be a little box with the crossed circle in the upper left where connection status is shown).

6. Start HTC Connection Setup.

7. Tap the three dots in the down-right corner of your screen and tap "manual select".

8. Tap on the country. This will open a list of countries you can select.

9. In the country-list scroll to "Interop Unlock" and select it.

10. Tap on the round ok-button at the bottom of your screen and wait until connection setup is finished.

11. Tap "Done" to exit the app.

STOP - read this first. When you press Done you are taken back to the apps list. Quickly Uninstall HTC Connection Setup and never allow it to run again.

12(new). Power off and back on phone.

13(new). Go back to Setting/Cellular and set Mode to CDMA. Exit to main screen and verify 3G is there.

14(new). Go back to Settings/Cellular and set Mode to Global. Exit.

15(new). Uninstall the HTC Interop Unlock.xap

You are DONE!

Thanks goes to all on this thread for supplying methods and tips towards this particular phone. I have found this method does not loose 3G (HTC connection setup really does no good with the CDMA network so it used only once for Interop Unlock; if it ever runs a second time it screws up the CDMA data connection).

Hello!

I had made the Interop Unlock at my HTC Trophy (ChevronUnlocked).

It works fine, but when i will install WP7RootTools or TouchXplorer or Bazaar it does not work. Also Error 0x81030120

I try Tom XAP Installer, but there is error: Make sure that your phone is unlock or Zune is running.

When i install WalkManGo or BatteryStatus it works fine with no error.

I try to install the InteropUnlock new. I delete HTC connection Setup und HTCInteropUnlock. I restart my Phone and install Interop and HTC Connection Setup new, but when i open a list of countries, HTCInterop is not there?

What is my Problem???
[Windows Phone 7 Development and Hacking] Heathcliff74:
Have tried to scroll down in the gprs menu? If it is really not there, I'd like to have a copy of your diagnosis app for analysis purposes. Please download the Mango webserver. Run it and configure it (IP address setup and provide password). Use your PC to connect to the phone. Open this in your webbrowser: http://<yourphoneIPhere>/Windows

There are a lot of files. One of them is called DiagnosisApp.xap. Download the file with your webbrowser from the phone to the PC and post the file here.

Thanks!

Thanks for the detailed steps. I will add it to the opening post and give you credits for this explanation.

If you have error 0x81030120 you are simply not Interop Unlocked. Current version of WP7 Root Tools doesn't work on HTC, but you can use it to see if it gets deployed to your device, just to see if Interop Unlock is working. You should see "Interop Unlock" in your country-list, according to the instructions in the opening post. If that is not there, then I think you did something wrong. Read the instructions in the opening post very carefully!!

Ciao,

Hi Heathcliff74

I had installed the Interop Unlock with the instructions in the opening post.

In the country-list i insalled HTC interop.

After reboot i must install the Repair HTC CS.xap because HTC Connection Setup will start after every reboot.

I try to install TouchXplorer, but it came Error 0x81030120.

Now i try to install HTC Interop 2nd time, but in country-list is no HTC Interop.

Must i do Hardreset or something???
[Windows Phone 7 Development and Hacking] Heathcliff74:
Don't hard-reset. That won't help.

I'm quite sure the Interop Unlock hasn't worked for you in the first place. Even though it seemed to install, it probably got rejected. Probably because you drivers are too new. Read info in the opening post. Maybe it can be fixed by restoring your last backup.

Heathcliff74
[Windows Phone 7 Development and Hacking] Björn-SH:
you write that my drivers are too new.

which driver do you mean exactly?

I have WP7.5 Version 7.10.7740.16
[Windows Phone 7 Development and Hacking] Heathcliff74:
7.10.7740.16 is your Windows Phone version. You get updates for Windows Phone from Microsoft and from HTC. The latest update from HTC makes that my HTC Interop Unlock (in opening post) doesn't work anymore. I'm still looking at the new drivers to get it working, but I'm working on a lot of projects now. So if you restore a backup and that backup removes the last HTC update you can probably do Interop Unlock. All this info is in the opening post too! Please read that before asking more questions.

Heath, you have any idea on whether or not the latest Verizon Trophy update is going to break the Interop unlock for the Trophy?

Or is it just planning on fixing that loss of 3G issue (which I experienced once myself, not while unlocking, just was playing with connection setup and ran it twice).

I'm trying to do it on the Verizon Trophy now, and when I start connection setup after going GSM mode, it gives me this:

[Windows Phone 7 Development and Hacking] dreamcaster012:
When I change my celluar connection to GSM and enter the Connection Setup application it says that it can't continue because I don't have a SIM card or a PIN number, under Cellular in settings it just says "Invalid Sim" and the icon is like a paper with a circle/cross through it (rather than the general 3G bars or no connection bars).
