make a backup with my method and try it. If works, yeaheee. If not restore your backup and wait the progress of this unlock method
PS. LEAVE US A FEEDBACK AFTER THE ACTION .....

Doesn't work on my first generation Omnia 7. It says I have to dial *#9908# in the diagnostics tool, which opens up the GPS manager. There is no option "WindowBreak" there.

Did you uninstall the diagnostics tool, and reinstalled it again after the unlock?

Works perfectly on my Omnia 7 broke my 3G but it was a easy fix to restore it.

This method worked for me (Omnia 7, latest Mango version). I don't know what type of unlock it provided, but I'm able to deploy xap packages without problems now. Also, I don't know if this was happening before or the unlocking screwed it, but sometimes the 3G is not working till I reboot the phone.
Anyway, nice job!

yes, it causes from unlock process. here the fix Samsung Repair 3G by Heathcliff74.xap

Stock Omnia 7 without branding. Updated via Zune "Force Update" method. Mango Version: 7720.68. Firmware: 2424.11.9.2 // Radio: 2424.11.9.1
Set "windowbreak" active via Save in the GPRS Manager. Rebooted. Sync partnership in Zune is set to "Guest". Deployment of "WP7 Root Tools" was not possible with following error msg saying that my device does not support interop unlock apps.

Found the solution to my problem:
- Connect your Omnia
- Start Zune and wait for the Omnia to show up
- Establish a sync partnership if you haven't done already
- Run WPConnect
- Close Zune
- Unlock your Omnia (Screenlock)
- Deploy XAP

I didn't at first, but I retried after uninstalling the diagnostics tool, and still the same result. It opens up the GPS manager, and there's no option "windowbreak" in there.

Ok, I just did a complete reflash to JK1 and then went through all the updates, and now it's working! I did that because my compass wasn't working either - my firmware got stuck at JJ6 (probably because I updated the radio rom without updating the firmware once)

if you unlocked your phone with chevron or any other registry editor you are fully unlocked. However if you have a true developer unlocked phone (via a dev account with MS), then you cannot install interop apps on Mango. See here for details.
A user with a legit dev unlocked device cannot deploy ID_CAP_INTEROPSERVICES xaps. They just get the dreaded E: 0x81030120 error.
Here is what the expert says.
but there is hope for Samsung and HTC users. Heathcliff just released a new procedure to fully unlock without going back to NoDo here.
---------- Post added at 02:02 AM ---------- Previous post was at 01:54 AM ----------
btw. there is another thread announcing the app. Schaps also updated the registry editor which works fine on my LG Quantum.
there is no straight forward way to uninstall the newly installed apps from the settings page. I successfully uninstalled with XAPDeployX. Sideload the xap again and check "force uninstall if application is already installed". Then click deploy. The program will uninstall the existing one on the device first and report this in the deploy tool with a success message. Right then you unplug the phone from the USB. Voila - it is now uninstalled and gone from settings.
Somebody else posted that you can install an older version (e.g. v1.3) that will show up in apps. Then you uninstall and it normally and it will be removed from settings as well.
just in case it doesn't work for you and you want to remove it...

if you are on Mango until now only LG users were able to get into the registry via the MFG tool to unlock their devices. Other users would have to go back to NoDo, fully unlock, set measures to prevent relock and then upgrade. But Heathcliff seems to have found a way to do this without going back to NoDo. He seems to be very close to a solution, working on Samsung and probably soon on HTC as well. I'd suggest you wait and follow that thread before going the painful back-to-NoDo route.

I'm on Mango beta. To install the official release, I'll have to revert to NoDo. I did on a previous phone, and escaped unharmed.
So depending on which arrives first, how do I fully unlock, etc. before installing the official update? I tried previously, but must've done something wrong because it didn't work.
I am following Heathcliff's thread. With reverence, awe and bated breath.
Again, thanks.

Many believe that if on 7720.68 you will just see firmware and radio updates rolled out to your device and you are all set. We really do not know at this point and might as well throw a coin. There seems to be some evidence that those on 7720.68 won't have to roll back.
If you do have to go back then unlock and stay locked using these guides

im on unlocked samsung focus mango 7720.68 using version 1.4
deployed OK & showing under settings but when clicked i get error "UnauthorizedAccessException"
then if i hit OK then the app opens but i do not think its working correctly after that

i managed to start the HTC interop unlock !!!! and now ? what is the next step ????
what can or must i do to unlock this phone ?????
Windows Phone 8 can install xap's, this does not mean it can run or start them if they require interop unlock. Currently interop unlock is not possible.
pffft...finally got this (allmost) working...
it doesn't lett me in several of these folders....
working on it...i will update later...
You can change any value by Registry Editor and save ? (or not - I think so not)
For check you can try to install an application that needs access to the root eg: Shutdown: http://forum.xda-developers.com/showpost.php?p=21751650&postcount=1
You can install app but not run (when tap, app is back to the apps list).

Oh wait it's only for Windows 8 WTF? There is no way I'm going to upgrade to that crappy os.
Very nice news! Hope to see this on HTC 8X too!
i follow you men!
i have an HTC 8S too, i will install VS 2012 and make DevUnlock with the SDK tools.
i will help you if you need testers, i am just begginer i can not help you to develop.
wp7mktplace cant sign these apps anymore
try other things or already signed homebrew apps
It possible to call all funcs from system dlls. But a lot of funcs returned Access_denied.
How about we all save some time and stop trying this silly idea, huh?
The interop unlock you're trying to install was for older HTC WP7 devices. It doesn't work on newer devices, and it certainly won't work on WP8 devices. The apps won't work for two reasons:
-Your device isn't interop unlocked
-The binaries are compiled for WP7, not WP8. Not even simple innocent apps like Orientation Lock run under WP8, because they aren't compiled correctly for WP8, nor do they use the correct APIs.
What should be encouraged, however, is an evaluation of the OEM apps on the device, to see if any have exploitable holes. I'm guessing that HTC has learned its lesson by now, but hey, worth trying.
Also, I'm curious to see if this XAP will do anything if sideloaded. I'm guessing no, as it won't have interop privileges, but I'm still curious to see what happens.

I'm with you, trust me I want the same thing... I have a edu Dev account and I am sick of the 3 app limit, never mind the lack of custom colors (Advanced Config), It seems a interop unlock for my 8X would be the only thing I need now to enjoy it more.
As long as these apps will work with a 8X of course

Probably you have Preview for Developers already installed and you performed a hard reset.
After a hard reset, with OS Preview installed, it "break" the license of oem applications during the configuration of the phone, and this is why Windows Insider crash.
The solution is flash a rom.
Do you know if there is the possibility of having issues with the botloader and not be possible to use recovery?

Also I would like to know if there is any way to stop the update from installing by itself after the download is complete. Pls help....

change the server
This is my first post. I have successfully installed WP10 on my lumia 620 using the chinese method. Everything went good as expected.
Now i feel more confident to try the detailed method given in other thread so that my data doesn't go through a chinese server.
So my question is: I already have WP10 on my phone. If i have to reinstall WP10, do i have to do full reset with windows phone recovery tool, or is there any other method.
I tried no 520

*Don't try it on Ativ S, unless you've somehow already secured the 8.10.14319.341.
Otherwise, faking your phone's identity will make it go through this update (before even thinking of WP10), which makes Ativ S phones reboot in a loop, forcing you to reflash your phone. That's the state my phone is in right now (I knew what I was walking into, I just wanted to try it)

How to turn it ON?
Sry Im new in Windows phones...I really need closer explanation on this...Maybe step by step
I download file that you gave me and now..? :silly:
On your phone go to "Settings/Update & Security/For developers" and enable "Developer mode" (this is only for W10M Insider, not for 8.1)
also dont forget install WP SDK on computer for XAP deploy
Im using 8.1 and I don't have that option...I have Update & Backup. So I need W10...I still dont have update from my career.
Can I update on some other way dxdz?
I must install this, right?
SDK 8.0 is too old not recommended... you must use newer SDK...
full VS comunity free version (but dont forget to enable phone tools installation -
)
or SDK 8.1 lite http://dhost.info/vink/avink/forums/viewtopic.php?f=10&t=4&sid=ccbd2d48ec5475ae2495402fe47fe82f
and Win 10 not officially relesed. only via insider testing
ok, what should I do after I finish this? like in this description https://msdn.microsoft.com/library/...UsingtheWindowsPhoneDeveloperRegistrationTool ?
Cant communicate with device...
you dont need to run developers tools, only installed...
to deploy XAP file to phone use deploy tool, but dont forget first upgrade to Windows 10 and enable developer mode

Yes, but this is confusing for me...
Windows 10 not released yet and you need to join test program called "Insider"
join with your microsoft account to https://insider.windows.com
install Insider app from store and with this app you activate upgrade to Windows 10...
dont forget, Windows 10 for phone is still in testing stage and have many bugs and problems...
Ok, this help a lot...But tell me, if I do it and after that I want back to stock. Can I manage to to that?

Problem with Google Pay on EMUI 9.1

Hello,
i have the problem with google pay.
The safetycheck says cts: false.
I have the build 9.1.0.241
who can fix this problem?
thanks in advance
I had the same, it's not verified by Google, I went to 9.1.0.311 and it worked fine.

It's not fixable without a firmware flash
It looks like this is a pretty common issue with P20 Pro users and here isn't a solution or a fix yet. Download to 9.1.0.311 until a fix has been implemented.

Install Huawei HiSuite on PC, Connect your phone to PC, once the HiSuite recognized your phone, go to Software Update, it will say your phone has the latest software available. Click the "Other software versions" (or something like that) below, and it will show you the earlier firmware versions. Select something you know it works well, and just go ahead with it.
You should also backup your data using HiSuite before doing the downgrade, just in case if you need to restore them later.
