[Windows Phone 7 Development and Hacking] GoodDayToDie:
Found a potential new way to interop-unlock *all* phones, even ones like Dell or Fujitsu/Toshiba. I haven't made it work yet, but the chances are pretty good. It requires messing with a carrier-specific file, but I think this file is present on all phones and can be customized for each.

Details forthcoming when I know more. If you want to help out during exploration of this, please PM me. I'll post publicly when I have a real test ready.

EDIT: Heathcliff74, please check your PMs. :-)

Hi, Heathcliff74, any progress on finding exploit in the HTC Mango Drivers v2? Thank you !

Will this cause purchased apps to identify the phone as a different one using the marketplace device limit for purchased apps??

Someone on a Focus S reporting

exactly

the same issue I had on my Focus after running an interop-unlock and repairing 3G settings.

3G enabled + wifi enabled = most connections time out

3G enabled + wifi disabled = Normal data behavior

3G disabled + wifi enabled = Normal data behavior

Hard-reset of the phone finally fixed it...but I lost the interop-unlock in the process (of course).

I'd recommend putting a warning in the original post about this issue. Its probably a bad idea to interop unlock any Samsung phone until a method is found to fix the resulting data issues.

Okay so I reverted back to the v1 update. This is before the IS feature got turned on. I did the unlock but it didnt work. So I uninstalled CS. But whoa HTC Apps disappeared from the Marketplace. I still have HTC Hub so I tried to get access from there but it looks like I "debranded" my phone from being a HTC anymore.

Something is definitely happening here.

update: okay well did a hard reset, tried the unlock again. didnt work. still could access htc apps though.
[Windows Phone 7 Development and Hacking] piaqt:
Interop-unlock worked on my HTC Surround: I now have registry access, but file system, no. Anyone else? Possible cause/workaround?
[Windows Phone 7 Development and Hacking] GoodDayToDie:
@piaqt: the HTC update that was bundled with 7720 for most people (which is also the one that broke using \Windows\CustClear.provxml to unlock) modifies the system DLL that TouchXplorer and similar apps used. Those apps no longer work on most phones.

I've avoided getting that update, because TouchXplorer is very useful to me as a hacker. i've tried to find a way to make it work again, but so far no luck. Heathcliff74 says he can port his WP7 Root Tools - which includes filesystem access - to HTC, but that it's a lot of work (and I know he's been busy as heck).
[Windows Phone 7 Development and Hacking] MeatHead88:
I'm all set :)

I've been running interop-unlocked for about 2 days succesfully so last night I made sure Connection Setup was uninstalled then proceeded with the HTC Update.

The HTC Update installed and i retained my 3G !

Connection Setup is both a savior and a devil! :)

I won't be reinstalling Connection Setup anytime soon....

[Windows Phone 7 Development and Hacking] sinister1:
That is strange, min works great and 3G is still runing the only errers I get is from Connection Setup when ever I reboot but I just ignore them. also I get errors when changing accent colors whit the Advance Config tool but I hit cancell and it still works. Just waiting on a dang file explorer so I can make my own coustom alerts.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
You should be able to use provxml to copy a file to the \Windows folder and add it to the Alerts list in the registry, then you can set it for your sounds.
[Windows Phone 7 Development and Hacking] dopecoder:
thanks, used HTC Interop Unlock.xap on my HTC Trophy with a chevron unlock and i didnt have HTC update installed.

WORKED!!! checked by installing advanced config, it worked.

Question: can i update my phone with the HTC update? will it not lock the interop-lock again.

Also i tried to install 'registry editor 1.2.00' xap it didnt work on trophy, told me cannot access regstry, is that an issue with the unlock or is it the app? any other registry app you guys can recommend.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Updating should not re-lock the phone (no current updates are known to do that). Major updates may do so in the future.

You need a newer version of Registry Editor that is Mango compatible. 1.2 is quite old.
[Windows Phone 7 Development and Hacking] benneh:
Mine relocked. Rolled back to premango backup, installed the interop unlock, installed reg editor and advanced config no problems. Then installed all available updates which took me to 7.10.7740.16 (HTC mozart, debranded), and I lost interop-unlock and my developer registration. Added it back as a registered developer device, but can't deploy interop hack again now :(

Still this got me where I needed to, was able to make a crucial registry change while I had it unlocked.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
Mango will lock your phone, yes. I believe NoDo did too. That's what I meant by major update.

The whole point of this interop-unlock is that you use it on Mango, you don't roll back to pre-Mango. Nobody who has any need to use this update (i.e. they are already on Mango) is expected to have their phone re-locked by 7740 (a minor update) or by an OEM update.
[Windows Phone 7 Development and Hacking] Heathcliff74:
I see you have firmware version 2250.21.51003.901. I'm not sure, but I think those are the HTC Mango drivers v1. If that is correct, you're good to go.

I have my HTC device updated to latest firmware for hacking purposes. It runs 2250.21.51004.401, which is newer than yours. These are the HTC Mango drivers v2. On this firmware the current exploit doesn't work anymore.

Ciao,

I'll back this theory up with the conflict on data connections. If I enable the Wifi, I still feel sometimes that it's using the data connection. Things time out and what not, so i disable the data and 3g, and i get things to load. Weird
[Windows Phone 7 Development and Hacking] Heathcliff74:
If you look at post #10 in that thread you see that this problem is probably due to Internet Sharing. Could even be a WP7 bug as HTC seems to suffer from the same issue. Please verify that you have Internet Sharing on your phone.
[Windows Phone 7 Development and Hacking] Heathcliff74:
It seems that the second generation HTC devices will be getting an update very soon. If you'd like to keep your chances of getting Interop Unlock as high as possible I suggest you don't update your device yet. I'm working hard on the HTC Mango drivers v2. I can't tell you *if* or *when* I can make Interop Unlock for it, but I'm making progress.

:( They hate hackers / homebrew that much? Hiss, boo.
[Windows Phone 7 Development and Hacking] GoodDayToDie:
It's really rather funny, actually - first-gen HTC WP7 devices, with their unlocked bootloaders and lots of easily-used high-privilege DLLs, were the most hacker-friendly option. Now, with them trying to lock down the SPL and blocking all those wonderful DLLs from doing anything useful (including interop-unlock in many cases), they are becoming more frustrating all the time. I'm really wondering if my next phone will be an HTC after all...
[Windows Phone 7 Development and Hacking] Heathcliff74:
Heheh. I would call my relationship with Microsoft a love/hate relationship. I totally appreciate their products. And I see the beauty of it. Even their security mechanisms are beautiful. But they should REALLY allow some sort of full unlock/root for tweakers, like us. But I understand them. There are big interests and a lot of money at stake. So they protect their products. That's life. Anyway, I just hack for fun. I love it when I can out-smart the pro's somehow. :D

@benneh, clarify please: Did the interop-unlock process work, or do you simply still have the interop-unlock you had before?

Thanks.
[Windows Phone 7 Development and Hacking] benneh:
Ah thanks, sorry I misread the following thinking there wasn't any current updates which would overwrite the unlock...

I rolled back once again, upgraded to 7.10.7720.68 and applied interop unlock. It's now survived two subsequent HTC updates.

---------- Post added at 03:31 PM ---------- Previous post was at 03:29 PM ----------

No interop was just remaining from before. Would a capture of the latest HTC update be useful? Could rollback and capture if needed.

It doesn't work on my HTC Mozart...Os version: 7.10.7720.68...It doesn't show any error either. I did it many times, but couldn't make it work. I thought restarting the phone would help, but it didn't work either :(

Mozart had another HTC Update yesterday, let's call it HTC update #3. Unlock made before installing the tethering update (#2) remains.

FW after #3 is 2250.21.51101.401

BL is 5.11.2250(133487)

Just for the skeptics. If you read the thread (painfull, OK), it works on Mozart BL 5.x as well as system 7740, you just cannot have the tethering update. Phone remains unlocked after the tethering update and after yesterdays update #3.

That's all I want on my Titan.

I have no problems at all with paying for software but that one seemingly simple thing requires such a heavy system hack..

Yes, you can.

I searched the thread and didn't find anything else about this. Is there any news about the Titan?
[Windows Phone 7 Development and Hacking] anttaz:
Even if you interloop unlock titan advance cofig does not work nor will reg hack through provxml method. I am on first gen phone. Developer unlocked, Chevron unlocked and interloop unlocked and neither work for me even since aftet 7720 advance config of any version available does not work and HTC drivers will not allow through connection setup anymore. Same with registry editors no longer working because of nee drivers. These new first gen drivers came on 2nd gen devices from day one. Myself I don't think interloop unlocking alone will help you edit themes as it will not allow me to.

I have not hspl yet nor intend to as too much on phone to reflash. So just stuck without being able edit themes or reg.

[Windows Phone 7 Development and Hacking] benneh:
ok something odd is going on here. looks like interop unlock somehow disabled itself sometime in the past 24 hours... I did install the latest HTC update but it was working ok immediately after. Getting the message:

e.g. Supreme Shortcuts has been revoked by Microsoft. Please uninstall it.

I know from past experience these messages are when your dev unlock has been removed for some reason, so I tried to unlock again with Windows Phone Developer Registration Tool, but I keep getting the error:

Error Communication with the App Hub. Please set the correct date and time on the phone, check the Internet connection and try again later (ErrorCode:0x64)

Time is set correctly, and have tried manually and automatically setting the time just for good measure.

Edit: Never mind, I accidently removed my device in apphub. Apparently it appears there only as the devices original name, not it's current name, so I removed the wrong entry from my list of registered devices.

Reading allowed. For interop-unlock you need at least a developer- or chevron-unlocked device.

Or is it to install app only?

tnks...
[Windows Phone 7 Development and Hacking] GoodDayToDie:
It's not a SIM unlock. Nobody has been talking about SIM unlock anywhere else in this thread. Lots of people talking about installing apps with ID_CAP_INTEROPSERVICES and installing more than 10 apps and so forth, hopefully that makes it clear what this is all about...

Eh, you'll find that provxml works in certain circumstances - there are a few registry keys that can still be modified, and I think you can use provxml to move files around still - but yeah, the restrictions on the high-privilege DLLs are a real *****.

So Interop-unlock for the 2nd gen HTC devices is not going to happen?

LOL...that was a question. Just looking for a status. :-)
[Windows Phone 7 Development and Hacking] GoodDayToDie:
It hasn't happened yet. The sun also hasn't swallowed the earth yet. That doesn't mean it's not going to.

These hacks aren't something that happens on a schedule. It's research and experimentation. I might figure out a working unlock tomorrow, or I might die tonight. I can't see the future, and I doubt anybody else can either. People are still working on interop-unlock, though.

Hi all,

I unlocked my Mango LG-900 with this guide but every time I try to deploy any apps with one of many tools (ie. Tom XAP Installer or New XAP installer) it fails.

The error returned is this:

Connecting to device...

Deployment FAILED with the following ERROR:
0x89731812

I Googled it and searched on xda but it seems to be very uncommon error and I can't find a solution or an explanation for it.

Zune works properly...

Thank you in advance for any one wants to help me :)
[Windows Phone 7 Development and Hacking] Heathcliff74:
Try to reboot your phone and your pc and make sure your phone is not on the lockscreen. Then try again.
[Windows Phone 7 Development and Hacking] Sig. Gargiulo:
Thanx for the tips Heathcliff74...I forget to specified I already did it several times but without any benefits :(
[Windows Phone 7 Development and Hacking] Heathcliff74:
Does syncing pictures with zune work correctly (take a picture with your camera, connect with zune and see if it gets transfered to the pc)?
[Windows Phone 7 Development and Hacking] Sig. Gargiulo:
Sure, Zune works properly: music and pictures are synced from Zune to the mobile and viceversa :)
[Windows Phone 7 Development and Hacking] Ikkari:
I had the same problem with my Omnia 7, Zune was syncing fine...

But App deployment suddenly stopped working... Deployment on my Lumia 800

still worked fine...

-The first time i fixed it with a Hard Reset of my Omnia 7 (it worked for a while)

-The second time I didn't want to fix it with a Hard Reset:

So i tried different USB ports....

starting the Deployment Tool with Admin rights...

Restarting Phone and PC several Times...

Installed my missing USB 3.0 drivers...

Reverted to the old Windows Phone driver in the device Manager...

Uninstalled Windows Phone Device Manager from Julien Schapman

Updated again to the new driver in the device Manager....

Not sure what helped... I already had given up.... The next day it worked fine again.....

No problems since then

I've also installed the Networp Setup-tool from Nokia and your Interop-unlock XAP.

Also; when I enable flight mode and try again, I get a different error.

No idea if this is of any help :p
[Windows Phone 7 Development and Hacking] Briefcase:
The number of times you see the "Interop Unlock by Heathcliff" entries is dependent on the SIM card you are using. It doesn't matter which one you take, all entries do the same. Having one entry is not better or worse than having multiple in this case.

What does the error say when you put your phone in flight mode??
