how come i haven't get any update to 7740.
[Windows Phone 7 Development and Hacking] MeatHead88:
I've also tried toggling CDMA to Global and restarting, but the same behavior remains...no data and connection setup starts after each reboot.
[Windows Phone 7 Development and Hacking] Ttblondey:
any update for v.2 device?
[Windows Phone 7 Development and Hacking] hbxntsxw:
Today I update my mosart to 7440, but Zune delete the backup file automaticly.:(， and now I have no backup.
[Windows Phone 7 Development and Hacking] Ttblondey:
Where does it located i can't remember.
[Windows Phone 7 Development and Hacking] Core2pt:
i was with old advanced config.. now with last version it dont crash , just give some access errors time to time.

but i´m about 20 xap´s installed and interop unlock is ok

maybe the restricted access is about the app´s and not about the interop now

nice work

I have Mozart with 7740 and SPL 5.11

I followed the instruction but i still unable to deploy apps like Native Keyboard

I am using gold card now to restore my SPL

Thanks for all your efforts
[Windows Phone 7 Development and Hacking] Heathcliff74:
To get your data back you can try to install TouchXperience Advanced Config and go to "Tweaks" and check "Run Auto Data Config" and restart your phone.

You can get 7740 here.
[Windows Phone 7 Development and Hacking] Heathcliff74:
Read the opening post. If you have a backup from before your last update, you can restore it, apply interop unlock and update again.

Just for being up-to-date:

There is no Solution for devices with Bootloader 5.x and higher, right?
[Windows Phone 7 Development and Hacking] MeatHead88:
I'll let you know

thanks for the response! I'll try this as soon as i get home. I'm at work now and they would not look kindly on installing those types of support apps ;)
[Windows Phone 7 Development and Hacking] verynuclear:
I think so

I tried with no result
[Windows Phone 7 Development and Hacking] chriskay:
That is not true. I reverted back to a previous state and I could unlock it, although my bootloader was 5.10. It is the tethering update that seems to bring new drivers as Heathcliff74 pointed out already.
[Windows Phone 7 Development and Hacking] verynuclear:
My bootloader was 5.11

OS Version 7740

I tried many time without any result

Could you tell us what did you do exactly?
[Windows Phone 7 Development and Hacking] zepretender:
Hi !

I try to unlock my HTC Titan... but I don't understand : I can't deploy HTC Interop Unlock.xap with Tom XAP Installer... because my phone is locked !

Is this tutorial complete ? Is there a forgotten thing ?

[Windows Phone 7 Development and Hacking] Necroman_AI:
Hi there!

I'm using official Chevron unlock token on HTC Mozart with OS 7.10.7740.16 (without the tethering update), bootloader 5.1 and latest version of HTC Connection Setup on marketplace (1.13).

I can deploy the HTC interop unlock and choose that country on HTC Connection Setup, but i can't get interop unlock (i'm still limited to 10 apps and unable to deploy WP7 Root Tools, error 0x81030120).

I tried to deploy right after choosing Interop Unlock on country or after choosing my country on HTC CS.

After that i deployed Repair HTC CS and followed the tutorial on that, but still i can't have interop unlock.

Can someone help? Thanks!

EDIT: I reverted back to 7720 with the backup i had, but i'm still unable to have interop unlock using the tutorial. I go through all steps successfully, but no interop unlock in the end :(

Can you deploy apps like Native keyboard, Advanced config and Registry editor?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
@zepretender: This tutorial (obviously) required dev-unlock, since you're deploying apps to the phone. It does in fact say this, too.

Easiest options:

Paid AppHub developer account (http://create.msdn.com).

Student AppHub developer account (http://dreamspark.com).

ChevronWP7 Labs unlock (http://labs.chevronwp7.com).
[Windows Phone 7 Development and Hacking] Necroman_AI:

I tried, but this did not get my cellular data back.

I restored my phone from back up and tried again, but i'm in the same spot!

How come the "Interop Unlock" Country still exist in my Connection Setup even I reinstalled the CS?

I tried to update my HD7 to 7740 from 7720 AND STILL the "Interop Unlock" Country exist in the CS.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
The country/operator database isn't part of Connection Setup. It's stored elsewhere on the phone, normally in \Windows as part of the ROM. Removing Connection Setup doesn't remove the database, even the custom database we're using.

That said, running setup with the "Interop Unlock" country should remove the custom database. If it doesn't, then the only way to get rid of the entry (until Heathcliff or is able to fix it) is to restore from backup (the one the steps say you need to create). Sucks, I know.
[Windows Phone 7 Development and Hacking] Makker:
Heathcliff, thanks for all your hard work on this. Worked a treat on my HD7 with 7740 Mango. Small donation for all you efforts. Makker

update to 7740 still interop-unlock

thanks Heathcliff74,Kounadisk and GoodDayToDie
[Windows Phone 7 Development and Hacking] s10010001:
read the instructions carefully, the info you seek is in there. Its in a parts that says "This or This"

Edit: This this is the one I used, it does work! Read it carefully. After you interop unlock, get your data connection back to global in the phones setting under Cellular.
[Windows Phone 7 Development and Hacking] Heathcliff74:
There is a fix that works for most people. It's in the opening post: Repair HTC CS.xap.

VERY MUCH APPRECIATED, MATE!!
[Windows Phone 7 Development and Hacking] Necroman_AI:
I reverted back to 7720 with the backup i had, but i'm still unable to have interop unlock using the tutorial. I go through all steps successfully, but no interop unlock in the end (HTC Mozart, 7740 or 7720, btl 5.1, htc 1.13)
[Windows Phone 7 Development and Hacking] chriskay:
It is not the OS version that counts. Reverting back to 7720 would not make a difference as long as the tethering update (OEM) is still installed. I reverted back to a state prior to the HTC tethering update and could unlock my device no problem.
[Windows Phone 7 Development and Hacking] Necroman_AI:
I don't have the tethering update (at least i don't have that option in settings) and i just got the 7740 update yesterday (only the 7740 update from MS, not the update from HTC). I bought my phone one year ago branded to T-Mobile Germany. I debrand it and installed the official ROM from HTC for Mozart with 5.10 bootloader.

Here is my info:

[Windows Phone 7 Development and Hacking] prjkthack:
So does the HTC CS repair xap essentially overwrite the custom provxml file (the one put into the phone by your HTC interop unlock xap) with the original one that HTC CS normally uses?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Not quite - it actually overwrites the custom database file with one that will cause Connection Setup to ignore the custom database. That will cause the app to fall back to the official database of provxml files for actually setting up connections.
[Windows Phone 7 Development and Hacking] prjkthack:
Ahhh. Interesting. Thanks for the insight!
[Windows Phone 7 Development and Hacking] chriskay:
That is indeed very interesting... Hm. But as I said, I also have a 5.x bootloader, but after restoring a pre-tethering backup, I could unlock my phone no problem. If you say you never had the tethering update (or maybe any other HTC update) after Mango, then I am really not sure what else could cause this.

Just to double-check: your phone is dev-unlocked though, right?
[Windows Phone 7 Development and Hacking] Necroman_AI:
Hi! Yes i'm using official Chevron unlock token (I can deploy up to 10 non interop apps) on HTC Mozart with OS 7.10.7740.16 (or 7.10.7720.68), bootloader 5.1, latest version of HTC Connection Setup on marketplace (1.13) and without the tethering update.

I can deploy the HTC interop unlock and choose Interop Unlock country on HTC Connection Setup, but i can't get interop unlock (i'm still limited to 10 apps and unable to deploy WP7 Root Tools or Advanced Configuration, error 0x81030120).

I tried to deploy right after choosing Interop Unlock on country or after choosing my country on HTC CS. I even deployed Repair HTC CS and followed the tutorial on that, but still i can't have interop unlock.

Then i uninstalled CS and tried all over again, but no interop unlock.

Finally i reverted back 7720 with the backup i had, but i'm still unable to have interop unlock using the tutorial. I go through all steps successfully, but no interop unlock in the end :(

EDIT: So here is what i did next, a full reset (on 7740), applied official chevron unlock, followed the tutorial on first post and still no interop unlock. Tried to restore an even older backup from September but got an error and was to unable to restore. Now i will restore to backup prior to 7740 (7720) and stay with it until someone can help figuring this out?

Is there any other way to have interop unlock, besides using a custom rom?

Thanks!
[Windows Phone 7 Development and Hacking] MeatHead88:
Repair seems to do nothing for me...

The Repair Connection Setup.xap does not change the behavior of my phone at all. Is there anything I can do to force this overwrite manually?

Connection Setup still launches at each boot and I have no Cellular data.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
After installing the Repair app, you should be able to use Connection Setup to do the standard provisioning for your phone. Once you've done that, the problems should go away. Did you try that yet? Installing or running the Repair app is not enough by itself (in fact, running it does nothing at all).
[Windows Phone 7 Development and Hacking] Ttblondey:
does hard reset to factory setting can remove the IS and be able to interop-unlock my hd7?
[Windows Phone 7 Development and Hacking] Heathcliff74:
No. Updates survive a hard-reset.
[Windows Phone 7 Development and Hacking] Ttblondey:
guess i have to go back to nodo if i want to do the interop-unlock.
[Windows Phone 7 Development and Hacking] zyxer_raffy:
After updating my Unbranded HD7 to 7740, still didn't have the IS. :(
[Windows Phone 7 Development and Hacking] Ttblondey:
we need to downgrade atleast 7720 without the IS or NODO.
[Windows Phone 7 Development and Hacking] chriskay:
The 7740 update is a Microsoft update. The tethering update comes from the OEM and does not change your OS version number.
[Windows Phone 7 Development and Hacking] MeatHead88:
I've tried that a couple times...

Good Day, GoodDayToDie,

I've installed the repair app, re-ran conenction setup but no data. I've then rebooted, Connection Setup still runs by itself, with Verizon Wireless automatically and correctly selected. Connection Setup says it was successful and I hit "Done" but still no cellular data. My unlock remains solid, though :)

One note:

To get mine to interop-unlock, i had to use the method of switching cellular to GSM and waiting for no service and then opening Connection Setup... That is the only difference in instruction I had to use from the first page in this thread.

Thanks for your work on this and taking the time to help me and others out.

Can I TRY new HTC Interop Unlock on my shipped HTC HD7 Final Mango ROM (with Internet Sharing)? Or I have to have another ROM version?
[Windows Phone 7 Development and Hacking] jpmadeira:
I have a HTC Mozart and I still don't have the interop-unlock working on it.

I did all the steps with the different xap for htc unlock and when I want to select manually the country it happears always Interop Unlock instead of "Phone Customization" (and yes I'm using the new htc unlock file ). I do every step without an error but when I try to install TouchXplorer I get the famous error 0x81030120.

In every attempt i have uninstalled CS and the other unlockers and restarted the phone.

My Mozart info

os version:7.10.7720.68

Firmware revision number:2250.21.51007.401

Now i'm getting a pop up message telling me that i should update to 7740. Should I or that will get even harder to unlock the device??

[Windows Phone 7 Development and Hacking] Budniu:
What can I see folders and file in Touch Explorer with InteropUnlock ?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
@MeatHead88: You might need to put the phone back in GSM mode and run Connection Setup again to make it stop being a problem. You could then try enabling Auto Data Config (using Advanced Config or a registry editor) and seeing if that helps after switching back to CDMA. Sorry; I don't have a CDMA phone so I can only guess at things.

@jpmadeira: There's some evidence that the firmware version X.X.51007.X is the problem. If you've got a restore point prior to that revision, you could try rolling back and interop-unlocking the phone then. Otherwise, I'm not sure what I can do for you.

@Budniu: Unless you're on a custom ROM or have not received the very first HTC update for Mango (normally included with the Mango update itself), TouchXplorer won't work for you. It may be possible to work around this - that's one of the things I've worked on before and will try again - but so far no luck.

[Windows Phone 7 Development and Hacking] Ttblondey:
You don't have to try cause it won't work. I have tried all the 3 interop-unlock to my same device and spec as yours.the only way is what Heathcliff74 mention is to go back to 7720 state without IS or back to pre NODO.

Hi! I also have an HTC 7 Mozart but with 7.10.7720.68 (even tried 7740) and firmware 2250.21.50104.401 but i still can«t have interop unlock!

In the last one or two pages i explain in detail all i have tried to do to make it work, with no sucess! Can you help? Should i try your method instead of Heathcliffs?
[Windows Phone 7 Development and Hacking] Ttblondey:

Thanks a lot :)
[Windows Phone 7 Development and Hacking] Ttblondey:
Good news to maybe for everyone. I have found a way for those who have a backup of NODO and wants to make a restore point from it.Here's the picture. My restore point that i backup is from chevron unlocknodo with update rom,radio& bootloader. Edit : deleted some phrases and change the picture.
[Windows Phone 7 Development and Hacking] Budniu:
Ok, but if you later (after when you do backup) install HSPL and now you want restore system from that point, you have to install system from RUU. Then you don't restore from that point (I tried). You can restore ONLY with the system that created point - new install system = new system and can't restore from old point.
[Windows Phone 7 Development and Hacking] Ttblondey:
i'm not using custom rom. So i'm not sure how to do for custom rom.I have backup for the restore point my nodo and my chevronunlock with IS and from 7004.I'm not going to post the step because I need to run a few test to my device and hope to get to 7720 without IS so that I can interop-unlock my hd7.I still haven't restore my phone yet fyi.Maybe i will edit some phrases that I have post earlier.:)

---------- Post added at 01:14 AM ---------- Previous post was at 01:11 AM ----------

I apologise for any confusion that i have make.
[Windows Phone 7 Development and Hacking] MeatHead88:
I got mine to work, kinda..

I had to restore to a post-mango but pre-HTC Update to get this to work....

I followed the instructions on the first page again and they worked perfectly without the HTC Update installed...

I've been using the phone for about a day and the unlock seems to hold, even after rebooting multiple times, so then I connected to Zune and installed the HTC Update... and the HTC Update installed, rebooted my phone....

Then Connection Setup automatically ran and broke my 3G!!!! :(

so then I was back in the same spot i've been fighting, no 3G or cellular data, but interop-unocked...

I restored to my backup that I made that was unlocked and had 3G working, but no HTC update...

Seems everything is great unless you have that last "HTC Update for Windows Phone"..

I've have not tried installing that HTC update again because I'm workign pretty good now but if anyone has any ideas so that i can get that update, I'm all ears ;)

Thanks for everyone's help.
[Windows Phone 7 Development and Hacking] Ttblondey:
I totally don't have any restore point because I reformat my pc and uninstall and reinstall my zune a few times. I have find a way to 'make ' a restore point for my device.
[Windows Phone 7 Development and Hacking] jpmadeira:
I have no restore point available. I don't understand why because i didn't format the pc.

Looks like i will not have interop-unlock in a near future, which is a pitty. :(

Nevertheless I have to say "thank you" and "congrats" to all the people that made it possible for several guys to have interop-unlock.

[Windows Phone 7 Development and Hacking] Ttblondey:
I manage to create a restore point (see my 1st post picture )with my NoDo backup which I don't have after reformatting my pc and reinstall my Zune.I just worry that I might brick my phone due to bootloader,firmware,hardware and radio differences when I downgrade to NoDo.I'm sceptical on downgrading back and I'm still keeping it on hold.I don't use any custom rom or apply any rspl/hspl on my device.
