Unbelievable... I never thought that this really cool initiative would become that "hard"...
Hopefully everything goes well and that Heathcliff gets the phone soon...



Nice. :)
Any webshops with this price out there? :)

Cheapest from a webstore in my location is 178 euros, but they only deliver locally. I wonder if the ATIV S sales are rising because of its ridiculously cheap prices, specs that are better than the 920 in certain apsects or because it is the first to be Interop Unlocked? Well, most likely all three :D

sorry to say, but globally nobody cares about interop unlock - and certainly shops don't :)

Samsung GT-I8750: MSM8960 or no MSM8960?

Found this in the ATIV S registry.

http://wap.samsungmobile.com/uaprof/GT-I8750.xml

It mentions LTE under supported bearers. But this is for the GT-I8750, not the SGH-T899M, which has LTE.

Very confusing. The ATIV S has an LTE chipset (My ATIV S' drivers are all MSM8960), but is LTE disabled by Samsung to cut costs by just using one motherboard and disabling LTE on one and enabling LTE on another?

WindowsPhone.com mentions that the GT-I8750 uses a MSM8960 chipset (LTE chipset), and I sincerely doubt that windowsphone.com would get the chipset wrong for a phone with its OS.

Conclusion: Samsung uses the same motherboard on both the SGH-T899M an GT-I8750 to cut costs and on the T899M, they flashed ROMs with LTE enabled and on the I8750, they flashed ROMs with LTE disabled. Similar to the Lumia 810, LTE can be disabled even though it has an LTE chipset. Kinda expected this from Samsung...

This chipset supports FM radio ;)

For some reason i cant side load these files.. I have another program from the marketplace that i can side load on my SD card.. but when i go to the market place and click on SD card. I dont see your apps listed. Am i doing something wrong? I downloaded the files in IE and FF and nothing made a diff. I am also using the ATIV S Neo (I800) not sure if this will work.. but I saw somewhere that it should.. I also upgraded to GDR3 last night.. did i screw myself? I am also dev unlocked

You need to use the app deployment app from your PC. Click to open the deployment tool for either 32bit and 64bit.

I would like to know that, too!

@sireangelus: Did you finally send the phone?!?
@Heathcliff74: Any news?

@sireangelus was not online since october 15th. I haven't heard from him since. If he kept his promise last time, he sent the phone. But I have my doubts. I sent him 2 PM's since that time and I haven't gotten any response.

Maybe it's time to contact the Italian police. I have his full name, address, phone-number and email.

:( :( :(

It looks like that we have to do that.

Don´t forget that we have the postal receipt, too.

When he got the phone he had to sign for the delivery...

Hm...
the question is: Does the Italian police care, if non-italien people are complaining about an italian guy?
All this is very frustrating... I really hope, this situation isn't going to "kill" the goodwill of all the donator here on xda.
If we need to donate for another phone, i'll hop on, btw ;)

Hi Heathcliff,

I have emailed sireangelus and asked him to respond. Although XDA cannot officially police such matters, it is in the spirit of the community that i have asked him to contact you as there may well be a very good reason for the delay - we all have real lives and sometimes this interferes with life on XDA.

I hope that he responds positively soon. :cool:

Tim.

EDIT: guys, please do not dilate this thread with comments about the above, as it detracts the purpose of said thread, i will have a clean up in due course - thanks.

Hmm, it's a bit late for not being angry - but it's not to late for sending!

In the end:
Others have worked their butts off - not to get him a new phone in replace quick, but to get that "unique" phone to Heatcliff much quicker!

Please read my post above, the subject is not to be continuously debated over and over again, thanks.

Hello All!

First of all I want to thank all the devs for their work.
I have done the GDR3 updtate and today I make a Dreamspark acount to have a dev unclok for my Ativ S.
So far everything is good. Then I tried the Interop-unlock, and it works. I used the App deployment from the WP8 SDK to sideload the .xap.
And now I'm trying to sideload the BootsraptSamsung_Release_ARM.xap file on my phone. I have the 0x81030120 error everytime and I'm limited to 3 .xap .

I'm trying different ways to make this working but nothing works.

Thank you for you're answers.

You didn't prevent the relock. The phone periodically "phones home" (once a day or so, plus every time it is connected to a PC) to check what unlock level it is supposed to have. Part of a "complete" interop-unlock is preventing this re-lock; there are two registry value which you have to clear. They should be indicated clearly in the tutorial. Repeat the unlock process (starting from modifying the MaxUnsignedApp value) and make sure you don't skip that part, then try sideloading the bootstrap app again; it should work and then allow you to run the capability unlock app.

EDIT: Updated the link in the first post, it was going to an outdated version of the app that didn't include the prevent-relock instruction. Sorry about that!

    It took us much longer than WP7 did, but the first Interop Unlock hack for WP8 is now available. It's currently limited to SAMSUNG phones, although we're trying to extend it to other phones, of course.
    WARNING: Samsung is trying to break this hack! If you take the retail upgrade to GDR3 including the Samsung firmware update, it will not work!

    A brief summary, for those unfamiliar with interop-lock: Windows Phone allows a number of high-privilege app capabilities, which can be used to make changes to the OS which are normally not possible for a third-party app. The limitation on whether we can use these capabilities or not is based on what "level" of developer unlock the phone has; standard "ISV" (Independent Software Vendor) dev unlock (max 10 apps or less) is what pretty much everybody gets; OEMs, however, get a special OEM Developer Unlock (300 apps or more) which gives them the ability to use much higher-privilege app capabilities than the standard ISV unlock permits. The name comes from ID_CAP_INTEROPSERVICES, the capability which was most important in WP7. In WP8, however, there are a great many interesting capabilities. Note that Interop-unlock by itself does not enable all of these. However, at least on Samsung phones, it is now possible to enable *all* the capabilities.

    Guide for Samsung's ATIV phones:

    The instructions are generally well-provided in @-W_O_L_F- 's app (direct link for updated XAP). You will also need the Diagnosis app, which is included (though hidden) on every Samsung WIndows phone.
    The instructions are as follows:
    • Developer-unlock your phone. You will need the Windows Phone Developer Registration tool for this; it comes with the SDK.
    • Sideload the helper app using Application Deployment (included with SDK) or WPPT. It does not work to just copy the file to your phone, or similar.
    • Open the Phone dialer (the built-in one) and dial ##634# to install the Diagnosis app (if you hadn't already). You can exit it afterward.
    • Run the Interop Unlock Helper app and read the instructions, clicking Next until you get to Step 2.
    • Click the button to generate the toast notification for your phone's Diagnosis app, then tap on the toast to open the hidden registry editor.
    • Press-and-hold the Back button, and switch back to the helper app without closing the registry editor. Click Next to go to Step 3 in the helper app.
    • Copy the provided registry paths and values out of the helper app, use the Back-and-hold switcher to return to Diagnosis, paste the values into the registry editor, and write them.
      Don't worry if the app says a write failed! Just hit Read afterward to verify the change.
    • Repeat the previous steps a few times, hitting Next after each set of instructions, until the Helper app says "Finish".
    Once all the registry values are written, congratulations; you are interop-unlocked!
    At this point, you probably want to run the EnableAllSideloading hack below.

    If you want to enable sideloading even more high-privileged apps, you'll want the following:
    1. Install the BootstrapSamsung app attached to this post. This requires having interop-unlock already, and will not work if you have Samsung's ships-with-GDR3 firmware update unless you unblock RPC.
    2. Run the app once, and ensure it displays a success message. You may then exit and (optionally) remove the app.
    3. Install the EnableAllSideloading app attached to this post. This requires the bootstrap step. However, it is not specific to Samsung (we just can't bootstrap anything else yet).
    4. Run EnableAllSideloading once, and ensure it displays a success message. You may then exit and (optionally) remove the app.

    At this point, you will be able to sideload any capability, even the ones used for built-in apps and services. However, there appear to still be restrictions, even with a capability such as ID_CAP_BUILTIN_TCB. Multiple XDA members, including @Heathcliff74 and myself, are working to overcome these restrictions.

    It may be necessary to repeat these steps after a phone update.


    Capabilities which will be enabled, without further modification, by using interop-unlock:

    Note: This list is *just* the ones from Interop-unlock; it does not unclude the ones from EnableAllSideloading.
    • ID_CAP_CALLMESSAGING_FILTER
    • ID_CAP_CAMERA
    • ID_CAP_CELL_API_COMMON
    • ID_CAP_CELL_API_LOCATION

    • ID_CAP_WALLET_SECUREELEMENT
    • ID_CAP_WIFI_BASIC


    One of the goals of this thread will be to explore what we can do with interop-unlock, and look for ways to achieve full permissions. I think I've found one, but it requires the ability to write registry multi-string values. Basically, if we could add a "superuser" privilege, or enable the use of ID_CAP_BUILTIN_TCB, which already has it, this would allow the creation of "root" apps.

    Aside from myself, credit for this hack goes to @cpuguy for the Native Toast Launcher tool which permits accessing otherwise-unreachable code, and @-W_O_L_F- for helping put the pieces together. I'm not actually certain which one of us achieved the interop-unlock first; we were both working on it. @Heathcliff74 continues to be a help on the quest for full-unlock.

    The source code for the apps below is posted at http://xdaforums.com/showpost.php?p=45606584&postcount=88

    Root unlock achieved (EDIT: Sigh, not quite) on my ATIV S. Details forthcoming. In the meantime, rest assured: it is possible. This still won't let old apps be used, but it will let new "root" apps be written. Basically, an all-new WP8 Root Tools.

    EDIT: Agh. Still not working. I'm trying, though!

    Hi all,

    Sorry for this off-topic message. But everybody who concerns this, follows this thread. So I'll drop it here.

    Today something amazing happened. I received a package from Italy. It was the long-awaited Samsung Ativ-S developer device. Many people donated money so we could buy a new phone for @sireangelus and he could send his phone to me. Within a few days money was collected, new device bought and sent to @sireangelus. After that, silence... I sent several PM's to him often no response. Or messages of him trying to be funny or whatever. But nothing was sent. I'm not easily pissed off, but last week, almost 2 months after he promised to send the phone, I got really angry and I sent him a couple of whatsapp messages to convince him he should keep his promise and don't be an @$$. Today I received the package. :)

    This night I had some time to check it out. Conclusion: it is really a developer device and very valuable for research! Yay!

    I already had an incident with it. I connected the device in mass-storage mode to my laptop, while I already had a WP8 virtual disk mounted. Windows 8 decided that all partitions needed to be unique and it actually changed the entries in the partition table of the Samsung (!!!) It couldn't boot any more. Luckily, I could still use mass-storage, so I could still inspect the device. I found that the partition table was corrupted and I could manually fix it. Pfew! All is working well again and I can further dissect it.

    Thanks to @sireangelus for finally sending the phone. I advise you to act more pertinent the next time you sell something, in order to avoid that people are getting really pissed off at you.
    Thanks to all guys who donated to make this possible. I hope to bring you new hacks soon!!

    Ciao,

    Questions and Answers

    Can I install WP7 interop apps using this?
    They will install, but there's no point. They almost certainly won't actually work. Interop-unlock enables access to parts of the OS which third-party developers were not intended to touch; consequently, there's no backward compatibility. Even the methods used for native code on WP7 (which is different from, but nearly essential to make use of, interop-unlock) won't work on WP8. However, it should be possible to port many of those applications to WP8.

    Will this work on Lumia phones / How can I get this on my Lumia / Are you working on this for Lumia phones / What about HTC, or some other OEM?
    The current hack relies on a Samsung-specific component. Adding support for other phones will require new hacks. We are looking into it, rest assured; at this time, however, there is no way to gain interop-unlock on any WP8 device other than a Samsung one.
    EDIT: It looks like there should soon be a Huawei W1 custom ROM with interop-unlock included. I don't deal with custom ROMs, but you may be able to use homebrew apps on that phone too.
    EDIT: Lumia phones *can* be interop-unlocked via JTAG. However, this requires some extra hardware and some phone disassembly. Not an online hack, and not for the faint of heart.

    But what if we installed the Diagnosis app on a Lumia phone (using Fiddler proxy or similar) and then followed this guide?
    I repeat, Samsung-specific component. Nokia doesn't put the required services/drivers for Samsung's Diagnosis app into their Lumia firmware, so the app would not work!

    Can I upgrade my phone to GDR3 if I have this?
    Yes. However, be aware: if you install Samsung's updates that come with the retail GDR3 update, it will break your ability to re-unlock, or to use some homebrew apps! (Developer preview updates are fine, as those are purely Microsoft code and don't mess with the Samsung components.)
    EDIT: There's a way to unlock the Samsung services for full access again on GDR3. You still need to interop-unlock beforehand, though.

    Can I re-lock my phone if I want to?
    Yes, easily. The simplest method is to use the Windows Phone Developer Registration tool (the one that comes with the SDK) to de-register the phone (you can then re-register it if you want to get your normal dev-unlock back). This doesn't remove any changes that were made using the interop-unlock, though (for example, it won't undo the EnableAllSideloading hack, not will it set back the Full FS Access hack). Apps that require interop-unlock will still be installed, but may no longer run. To manually remove interop-unlock, you can reset all the registry values that were changed by the interop-unlock hack to their original values, and remove all the apps. There still may be a great many other changes that also need reverting, though, if you want to get back to stock settings. See next question.

    Can I get my phone completely back to stock settings without knowing every little thing I changed?
    Yes, a hard (factory) reset will undo all changes made by interop-unlock, or any apps (including ones that require interop-unlock), and will remove all apps. If you need to send your phone in for warranty servicing and are worried that they won't take it because you interop-unlocked it, this approach will fix that (they would probably tell you to hard-reset anyhow, if it's conceivably a software problem).

    Will the interop-unlock survive a hard reset?
    Not using this method! Read the question above. This unlock is purely in software, not firmware; it is reset along with everything else.

    Can I upgrade my phone to WP8.1 if I have this?
    Tentatively, yes! We're still working on figuring out exactly what WP8.1 means for the homebrew scene. The short version is that most apps and some (but not all) of the hacks they contain seem to still work, though. However, see next question...

    Can I interop-unlock my phone on WP8.1?
    At this time, I don't believe this is possible (unless you can use a custom ROM). One step of the process appears to have been "fixed" and we will need to find a different way. -W_O_L_F- has indicated that he has one, possibly coming soon...
