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?¨
PS Sorry for my english

The Solution my friend is to buy them from the market place
This is the only solution, firstly because this is XDA developers and piracy isn't tolerated
Secondly, MS encrypted the marketplace which stopped the use of these programs for any legitimate or illegitimate reasons. So, Buy them.
If you have brought them an you are wanting a backup of the XAP then this is still possible, XAPs can be made from installed apps.

decrypted official programs from marketplace

a copy of encrypted file (marketplace) installed on the device gives decrypted file (xap)

yup, this should let you backup installed apps as XAPs allowing you to install them In one go later, it also seems to backup the data sections of these apps too.
Ive yet to play with this but it seems like a good idea, I was helping a chap months ago with something like this but was PC based. Its very handy but you have to wonder if it wouldn't be better just to make a complete zune backup...

Thanks for your reply, Program Manager, all backups save score games ? ^^
If yes you are the best !

Error 0x89731812

Hello, I tried deploy a XAP in multiple ways, but I constantly get 0x89731812 error.
I use a Windows 8 PC (I think here lies the real problem, there are no tools for Windows 8)
I tried developer XAP Deployer
I tried TomXAP Deployer
I tried Windows Phone Device Manager (Never worked anyway)
Zune is running
If i sent the XAP via email to myself i can install it, but i want to install it from the PC!

[Q] Windows Phone App Studio

Hi , I Have an HTC HD7 with dynamics rom wp 7.8
I tried to use the new app studio by microsoft to make an app
i used the QR code to download it on my phone , but i couldn't install on my phone , there was like something wrong ,
I tried to download the certificate on my phone with no luck
I'll be thankful for anyone who helps me :highfive::highfive::highfive:

Hi,
I just want to register at Windows Phone App Studio and asking for a invitation code that requesting from Microsoft and after three days still haven't received.
Does anyone know where to get or how to get a invite?

Your devices will still need to be unlocked using the Windows Phone SDK. It doesn't matter if you use the WP7 or the WP8 SDK, they both have the stuff to Developer Unlock your WP7.5/7.8 devices. Your phone will need to be connected via USB for the unlock and the deployment of your apps. The app generated from the site will need to be downloaded and installed to your phone using the Application Deployment tool on yopur computer. Just make sure it says Device instead of emulator when deploying.

[Q] How to open or Deploy original XAP into WP7

Hi All,
I have been using my 2nd gen Samsung Win Phone for a while (Omnia W - GT-I8350 to be more specific). I have recently interop unlock it.
The main account on the phone is a US Live account. So the app store tied to the US version. I however now living in the UK and wanted to install O2 Priority Moments. The app is only on UK store and when I tab the link on O2 website from my phone, it doesn't allow me to install it due to country restrictions.
I managed to found the app page on my PC, and downloaded the XAP for installing via SD card. But my phone doesn't have a card slot. I tried to sideload the XAP using Deploy software. But it cannot be read by the application.
Also, I thought normal XAP should have no difference to a ZIP file. But those I downloaded from Windows Phone website just cannot be open with 7zip or RAR software. The same happens to another free app that I wanted to install, but only available in the Hong Kong store.
Can anyone shed me some light on sorting it out?
Many thanks,
Jack

As far as I know, XAP files cannot be opened and edited like, for example, apk files in Android, because Windows Phone isn't open source. Therefore, all the apps are protected from editing (you actually CAN open them in WinRAR!).
If you have a proper XAP file of the app, you should be able to sideload it with Tom XAP Installer for example. But I'm fairly new to the world of Windows Phone, so you might wanne wait for someone else's answer. In the meantime, take a look here, it seems to be possible to change your region and therefore download the app the official way: http://windowsphone.uservoice.com/f...-allow-changing-your-windows-id-live-location

I have no problem in deploying other homebrew apps and/or "modified" apps in to my phone. Only those XAP downloaded from the windows phone website, those supposed to be installed via SD card, does work for me.
Anyone know how to make it work?
Thanks,
Jack

I think it's because now apps from Marketplace are encrypted, so maybe only Marketplace app can decrypt and install them.
If you're phone is unlocked, you can make an archive file for each installed app and then save it into your pc (if you search in this forum you should find some threads about this item).
Winrar or similar software "don't know" they need to decrypt the xap file.
