[Q] interop unlock on lg 7 for other oem market? - Windows Phone 7 Q&A, Help & Troubleshooting

hello everybody, I really can't get modding with windows phone, sorry I've been with android so long and now is all different.
So I have a LG 7 with mango, I want to install the nokia market xap. I just can interop-unlock modifying the registry with the mgf app?
Is a reversible operation?
Thank you

Hi, I'm actually the author of the Nokia Market (and Samsung/LG/HTC/Dell marketplace) XAP. You don't really need interop-unlock; normal developer-unlock works fine.
That said, to answer your question directly:
Yes, you can use the MFG app to dev-unlock (and interop-unlock, if you want) your phone. The steps are available on the Dev&Hacking forum, in multiple places including the interop-unlock thread.
The difference between dev-unlock and interop-unlock from your perspective is the MaxUnsignedApp value - if you put it at 10 (the default for a normal dev unlock) you can install up to 10 homebrew apps (XAP files), and they can't use ID_CAP_INTEROPSERVICES (access high-permissions drivers to break out of the sandbox). If you set it over 300 (most people go for 2,000,000,000 or so) you can install more homebrew apps than you'll ever need to, and they can use ID_CAP_INTEROPSERVICES (which enables some cool hacks, for example the MultiTaskToggle app linked in my signature - it's still compatible with LG just fine). This is referred to as "interop-unlocking" the phone, and must be done after "dev-unlocking" (which is just tweaking a few other registry values).
The whole thing is completely reversible. You can reverse it using the MFG app again, for example. I think you can reverse it using the Developer Registration tool (part of the WP7 SDK, this is the program normally used to dev-unlock a phone). You can, for the "nuclear" option, reverse it by wiping / hard-resetting the phone.
Hope that helps!

a big thank goes to you

Does the 2nd generation WP7 handset can unlock or not?

I found there is a great deal of the new devices of LG,JIL SANDER Mobile LG-E906 ,only 199.99 on expansys.
If there is a way to unlock /jb these devices, it's the cheapest 2nd wp7 that I have found...

Thanks ,I just want to know are there any other way to JB it ,such as flash the Romer's rom,because I just know the HTC has difficulties to rewrite the SPL.I dont know whether LG is the same as HTC?
I don't believe there are any custom ROMs available for LG Windows phones, though that may be incorrect.
You can certainly developer-unlock the phone; this is possible and supported on all Windows Phone models, whether you use the developer tools or the ChevronWP7 Labs unlocker.
Assuming LG hasn't removed the built-in registry editor from their new ROMs, you can also interop-unlock your phone. This allows installing high-privilege apps. It's not a "full unlock" (and the term "jailbreak" is far too vague) but it does allow some useful capabilities.

So I can install the XAP which is not verify through the MS, right?
I want to know is it difficulty to make this device's ROM?
If the Jill Sander have the MFG Menue so i think this one is possible.

Homebrew Bluetooth file sending app

Hi,
exist or someone developing homebrew app for sending files over Bluetooth ?
Thanks.
not at the moment
that's shame
I think it will come only if MS decides to bring this feature to WP. Search this forum there are links where you can vote for it.
Actually, it *might* be possible to implement it using homebrew - there are standard WinCE APIs for BlueTooth. If they are available on WP7 as well as WinMo and Windows Embedded, and aren't security-restricted, then it could be done.
I'd volunteer to take a look but I'm working hard on something else (and far more promising, IMO).

Would be great if you tried once. What are you working on right now?
btw, your OEM marketplace xaps were great. Keep up the good work
Right now, I'm working on the HtcRoot project, and various offshoots of it. Essentially, I want to add the advantages of a custom ROM into stock ROMs and, where possible, without forcing people to reset their phones. Part of this process involves writing tools for my own use, some of which I also publish. For example, the HtcRoot Webserver has essentially replaced TouchXplorer for me, though TX used to be a standard part of my toolset.
Considering the existence of the Contacts Transfer app in the Nokia store, which uses Bluetooth to transfer contacts from other phones and appears to run on non-Nokia phones (yep, I used my own OEM Marketplace XAPs to get it), I'm pretty sure at least some level of access to Bluetooth is possible from a WP7 app (using native code, of course).

yes, lot of people miss sending the files via Bluetooth,
So if you can add it as first priority it will be very helpfull
for all of us "geegs" which want to use WP7 platform
as geeg platform.
Will you be able to convert Junos Pulse client for winmo
to convert WP7 to run it in native mode?
Thanks for info.

Yes, you are right. The Contacts Transfer App is proof that transfer via bluetooth could be possible. And yes, I installed the Contacts Transfer app using your app

[Q] Homebrew App Registry Access on 2nd Gen Phones

Hey folks, I've done a fair amount of reading up and have come to the conclusion that homebrew apps that access the registry to make changes to phone features (like Advanced Config) will not work on 2nd gen Windows Phones (like my Focus Flash) as the situation stands.
I've seen more complicated methods arise to make some of these same changes (complicated to me, likely not to many of you. I could make these hacks work if I needed to, but am as likely to screw something up). My question is, are we likely to eventually see these 2nd gen phones hacked and opened up the way the 1st gen phones were, with app registry access and even custom ROMs, or are we looking at a different landscape for Windows Phone these days?
Should I wait and keep my eyes open for the status quo to change, or am I currently looking at the extent of Windows Phone development/hacking for the 2nd generation?
Well, Heathcliff74 says that the next version of WP7 Root Tools (v0.9) will support Samsung gen2. WP7RT includes registry and filesystem browsing, but the new version will also allow you to mark any app for running always in TCB ("root" or "admin") which will allow you to use many additional apps, such as Root Webserver and a few other things I'me currently working on (installation of XAPs from IE for example, if I can make it work on partially-locked phones).

[Q] How to develop an C# Wp7 app that accesses the registry and change the same

I want to make a new App to change settings for my phone.
How do I create a C # App in WP7 that makes changes to the registry and files WIndows Phone?
You need a lot of stuff:
- installed Visual Studio + latest WP7 SDK;
- interop-unlocked phone;
- knowledge in C# and WP7 programming.
If you meet the above requirements, read (attentively) this: http://forum.xda-developers.com/showthread.php?t=1569832
And if you are building Windows Phone 7 apps, you qualify as a startup and can get Visual Studio for free from Microsoft:
https://www.microsoft.com/bizspark/Startup/Signup.aspx
This gets you a free MSDN Ultimate subscription for three years.
Still looking for this help

I am an average programmer, I have these tools and capabilities.
My intention is to discover how to access and edit the registry through my applications.
wp7roottools is a good choice, but would like to know how to do it from scratch to the end user does not need to have the application installed.

Microsoft does not help much in this case
Well, you'll need to know how to write native code (use Visual Studio 2008 and the WinMo 6.x SDKs or the CE 6 or CE 7 platform builders). Write a native DLL with a COM class that exposes the functionality you want. You can then create an instance of the COM class from C# and use that via the ComBridge API. You can read more on doing this in a guide posted by Heathcliff74 on the dev&hacking sub-forum; search "guide developers native mango" and you should find it.
However, that will only give you the APIs to access the registry, it won't actually give you the permissions. You'll have read access to only part of the registry, and no write access at all. If you want higher permissions, you have four options:
1) Write an app for full-unlocked ROMs only. Full-unlock ROMs run all apps with max permissions.
2) Write an app that uses one of the existing "root" hacks that elevate an app to TCB (for example, require that people use WP7 Root Tools with your app).
3) Write an app that uses ID_CAP_INTEROPSERVICES and the OEM drivers present on most phones to do high-privilege operations. This is how registry editors and such worked before Root Tools, but requires substantial work to support various different OEM devices and firmware versions, and some device+firmware combinations aren't supported at all right now.
4) Find your own new elevation-of-privilege vulnerability, hack up an exploit for it, and use that. For example, when I created the HtcRoot project, WP7 Root Tools wasn't yet available for my phone.

Thanks to previous answers, this really seems to get bad to be useful.
So need to develop a DLL with COM classes (for Windows Mobile 6.5) that has the functions I want and then invokes it. I carefully read the topics mentioned.
Answers to your bookmarks:
Option 1) My first application is intended for the HTC HD2 fullUnlock, I believe not having problems with permissions.
Option 2) Use third party tools like WP7RootTools is not very advantageous for the moment
Option 3) seems to be the best option, but as the knowledge needed to collect it?
Option 4) I think I still do not have sufficient skills for this option.
Very grateful for your help this is really helpful and appreciated.

[Q]File explorer?

Yeah, is there any file explorer for non-HTC phones out there? I'm tempted to get a lumia 800.
Several (and most don't rely on device-specific code the way TouchXplorer does). Hell, WP7 Root Tools has been out for over a year, though it used to be Samsung-only. However, all of the file browsers require at least interop-unlock, and most require root-unlock (or full-unlock). Only a very few Lumia 800s can be unlocked that far; it requires an older bootloader that new models don't come with anymore,a nd nobody has found a way to flash the old bootloader back onto them (the Lumia 710 can be reverted, but not yet the 800; the 900 and 610 never used the relevant bootloader).
Aside from the Lumia 710, two of the gen2 HTC phones (Titan and Radar) can be full-unlocked using custom ROMs. Currently there are no custom ROMs for the gen2 Samsungs, but if you get one with old enough firmware (unlikely, but you may get lucky) you can use WindowBreak and then install Root Tools.
Meh, so my best bet is to wait and see what WP8 comes up with?
The only reason is mostly using other formats (e.g. PDF) for different things. I'm not a huge internet user, and I'm not too jolly that I gotta move some files in the cloud and then download them to my phone.
I wouldn't hold my breath for a WP8 file browser. Microsoft does not seem to be interested in giving anyone this capability. Furthermore, it could take very long time until there will be any WP8 unlock, due to the inclusion of Secure Boot (if there will be any at all - in case Microsoft implements proper bottom-up validation it could be possible that no application can run on SYSTEM privileges unless signed).
Be that as it may, why is a file browser so important to you? I don't find it too helpful in WP (except for hacking/developmental purposes) as you have IsolatedStorages (which are a mess to dig in from a file explorer), other folders like Windows and the Zune content store (of which the latter could be accessed per USB if wanted).
Anyways, the HTC Titan is a very nice phone to have, and so is the Lumia 800. I wouldn't purchase too much after what is unlocked yet, but rather after what you find best value in.
