Idea for general (all phone brands) interop bypass (NOT UNLOCK) - but can it be done?

MOD EDIT: Thread closed by OP's request.
If you have used reker's proxy, you will notice the "by @reker" entry on top of the list with search results. If we could do the same with the SamWP8 tool (and link his app to a similar app page), maybe we could bypass the interop unlock requirement (the error you receive if you try to sideload a app with interop capabilities on a non-interop unlocked phone) because apps installed in the store don't get this check (as compu829 demonstrated by saying the original Microsoft youtube app contained the ID_CAP_MEDIALIB_PHOTO_FULL entry in the WMAppManifest.xml, and how could you install this app on phones without having an interop-unlock, exactly : the app was installed through the store).
Correct me if I'm wrong, I'm still learning how the WP OS is build and how it functions.
To admins, I can't post this in the Windows Phone 8 Development and Hacking thread because I don't have the required 10 posts yet.

Seems like a feasible idea, I'll take a look on how the store works but I think the XAP's still need to be signed by a trusted root to this works.
I'll post any updates here as I can't post on dev section x.x

This idea is older than WP8, and it doesn't work. First of all, the apps themselves (as opposed to the data about them) are delivered over an encrypted channel that uses certificate pinning; we can't intercept or modify it. Second, the Store will only install Microsoft-signed (and probably only DRMed) apps. Unsigned apps failed to install through this channel back on WP7. Third, even if we could install the apps this way, hey would still be unsigned. The OS would thus treat them as developer apps. Developer apps on phones where the MaxUnsignedApp registry value is less than 300 are limited to the standard third-party app capabilities, meaning no INTEROPSERVICES or similar.
By all means, go ahead and poke at it - WP8 has surprised me before with weaknesses it has relative to WP7 - but don't expect this to work even if you get past the first issue (which *does* exist on WP8).

Did someone contact reker? We need to figure out how he did this. I can't tell if he succeeded into linking an app to the custom app page because when I click install, I get an error message : "This app is not available for your region", maybe I need to change my region to China and try again.
@GoodDayToDie : Won't the phone be tricked by the store installation, thinking it's an encrypted app? Does it matter whether the app is encrypted or not if someone manages to link an app to a custom app page, because Windows Phone app weren't always encrypted to my recollection (this may predate the WP8 era, if so we're screwed ). And if it matters, can we encrypt the app ourselves by using a encryption method like AES, SHA, MD5, ... ? Unlikely hypothesis, but if someone would succeed in doing all this, could the SamWP8 tool be used to increase the HKEY_Local_Machine\Software\Microsoft\DeviceReg\Install MaxUnsignedApp value beyond 300 to unlock interop capabilities? Are the EnableAllSideloading.xap and Bootstapper.xap also usable on other WP than Samsung or do they need to be recoded to work on WP of other manufacturers?

EnableAllSideloading.xap and Bootstapper.xap depends on Samsung diagnosis tool and it's RPC server that runs on LocalSystem account that has "unlimited" registry access, it's not available on other manufacturers.
Tonight I will start my experiments on it.

I was wondering how you could flash the bootloader of Android on the Ativ S as the Secure Boot made by Qualcomm is locked by a blown fuse (it's a hardware issue, not only a software issue you must deal with).

SecureBoot checks signature of the bootloader by a known public key, the case is that Samsumg uses the *same* key for android and wp8 bootloaders.

If this checks out, what does it mean, could we flash android on the Ativ S? Or could you even make a dual-boot scenario possible? Great find by the way, :good:.

Yes, it's the same hardware as SGS3 Snapdragon 4 version. But let go back to the topic, if you have some question about it send me a PM or post on my R&D thread

@bruce142: The store may or may not care about the DRM - that was in place by the time WP8 came out, but WP7 didn't have it for a long time - but it absolutely cares about the signatures. More accurately, actually, the XAP install code (which the store invokes) cares about the signatures. There's no "tricking" it; the signature is quite plainly there, or it's not. You don't exactly have to look hard to find it. The app launch code *also* cares about signatures. Non-sideloaded apps won't have ID_CAP_DEVELOPERUNLOCK, which is a special capability automatically added to sideloaded apps to allow them to launch even though they don't have signatures. Without that capability (or rather, without the SID which the token of an app with that capability gets at chamber creation), the kernel will refuse to load the unsigned executable binaries.

I understand, the app has to be signed before it can be uploaded to the store, but does the developer of an app not sign its app when he assembles it or does the store sign the app itself? I see no threshold here, as signing an app is not a problem, or is it? I still admire that reker managed to make an app page by using a proxy which isn't normally there and successfully linked an app to it, which I was able to download and it contained elevated capabilities, I thought the ID_CAP capabilities were all interop capabilities (correct me if I'm wrong). Could someone make the old version of the Samsung Diagnostic tool available this way which users with other WP than the Ativ S/Ativ S Neo might able to use to modify the MaxAppUnsigned value and unlock more capabilities, or is this impossible? If only we knew how reker did this, ...

ID_CAP's aren't all Interop capabilities, most of them are available for every app, and the ones you posted are, afaik, normal ones that don't need and Interop Unlock.

GoodDayToDie is right. His answer is very detail.
You may replace a xap with homebrew one in theory, but phone will never launch a store app without MS signature. Every single dll is signed by MS, and phone will check it.

Few questions and opinions:
The signature is used only for allowing the app to be installed on the device right?
Is the signature after added to the app a constant for the whole time or is it changing from time to time?
If the signature is used only for allowing an app to be installed, can we somehow make an virtual MS Server (Using FIddler for example), who can clone the real one and give us an offline signing of the app`s when installing them?
Can a signature be pulled off from an original installed app and the be put in to an another one?

The signature is checked when running the application, every PE image on the device should have a valid digital signature.
You don't seem to understand how it works, the signature is any kind of hash, let's say, SHA256, of the entire file. This signature is encrypted with the signee private key. If you change one single bit of the file, the hash will change, and so the signature will be invalid.
There are few ways to exploit this kind of security, like generating a hash collision or breaking the private key, both would take million of years.

I do really don't understand the whole process I was just giving some noob suggestions.
It's strange for me that after the app is installed it doesn't require an active network to start.So I am wondering if it could be possible to trick the app to start somehow?

While suggestions are always welcome, you really should read up on digital signatures and how they work. @greenboxal's explanation seems like it might have gone over your head a bit... The fact that you didn't understand about ID_CAP_* also means you've probably never looked at WP development, or even looked at the manifest of a WP app, either; you may want to do some of that. Until you do so, it would be only by the sheerest crazy luck that you managed to hit on a solution, because you don't even know what you're actually trying to accomplish!
For example, it's pretty obvious why there's no need for a network connection to start an app, once it's installed. There's a license on WP apps, which is checked when the app is installed (requires Internet access) and is then valid for some time (never checked how long exactly, probably years though). The signatures are different. When the app is installed, the signing certificate (which contains the public key, but not the private key, of the keypair used to sign the app) is extracted from the app and checked to see whether it is trusted by Microsoft (the phone has Microsoft's certificates embedded in the OS; it doesn't need a network connection for this). When you try to launch the app, it checks to see whether the signatures on each binary (which are, as greenboxal mentioned, created by taking the cryptographically secure hash of the binary and then applying something like encryption to it using the private key) are valid (it applies the public key to the signature to get the signing hash back, and checks whether that hash still matches). We (developers) can't fake store signatures ourselves, because we don't have Microsoft's private keys. Therefore the phone wouldn't trust our signatures (make sure you read up on the concept of a "chain of trust" and the concepts of public key cryptography and public key infrastructure in general too) and would refuse to load the binaries. The process of verifying signatures is just a bunch of math once you've already got the public keys, and those are, as I said, extracted from the app at install (for individual apps) and stored in WP8 itself (for the Store-wide signing key); no need to access the network.

Thanks guys for clearing this up for me.I know that it`s not that simple as i say.Anyway, just keep up the good work.We the Noobs depend from you.
If you are not those who you really are i personally know that i will never buy a Windows Phone again.You are the reason for the MS`s profit.
Sorry again for jumping in into this "battle".

This thread is becoming way out of hand, question is asked and answered : adding a app via proxy which may interop-unlock other WP is not possible. Locking thread now.
PS : yay, ten posts.

Brute Force Bootloader code

I am trying to develop a script that will brute force the unlock code for the boot loader. I just need some example codes, in order to find a pattern. (Also the length of the code). I have a prime exclusive so I cant get the code from Motorola.

You should try again. My understanding is that Amazon Prime dropped that stipulation and some people are getting their unlock code.
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
Make sure you use the scrub tool even if you know you have scrubbed it correctly yourself. It will make the e-mail unlock boot loader button appear.

I hope you get it, I'm on the same case with this amazon stuff... But you can check this:
https://github.com/pjobson/moto_z2_force_oem_brute_force_pfc
https://github.com/AProgCat/bruteforce-bootloader-unlock
So.. It's nearly impossible to get that code

is there away to port the key to hashcat to crack it?

this is something I theorized about doing, but never got too far into. I was trying for more of an exploitive way to give the code from the site and trying to find a way to bypass the check on the site to just give the code rather than bruteforce

How to Remove FRP Lock From Android Device ?​
The FRP feature is always enabled on your device as long as you have an active Google account. To disable FRP, you must remove your Google account.
To remove your Google account, follow these steps:
1 : From any Home screen, touch Apps > Settings.
2 : Touch Accounts > Google.
3 : Touch your Google account, and then touch MORE > Remove account.
Important: If you are sending your device in for service, selling your device, or giving it away, it is very important that you remove your Google account and reset your device.
Share it.

Have a look at my posts on this subject.
Currently I'm looking into whether I can side load some code via a FAT32 formatted SD card, and if possible, I need to locate where the flag is stored which sets this FRP. Now this could be stored on a rom chip of sorts and at this stage I dont want to break open the device to desolder chips, so this blog could be useful at giving clues into what needs to be looked at. Although the device is a Blink Mini camera, the technique can be applied on other devices, like smart phones.
Blink Mini RE, Part 3 -- Staring into the eye of the binary
If we stare at a binary for long enough, we will intimidate it into giving us its little secrets
astrid.tech
Ideally, I'd have a working device, dump the rom contents, then trigger the FRP and then dump the roms again to compare whats been changed, which would hilight areas for further investigation and maybe even the bit flag in question.
The other area of interest currently is Wireshark with the USB packet sniffer. Lenovo's/Motorola's Rescue and Smart Assist program aka LRMA can interrogate the device via a USB cable and detect the firmware. LRMA also suggests enabling the Developer mode/USB debugging which is enabled by clicking the build number seven times in the Google Android settings. So the question is can LRMA detect the FRP has been set? If it can, Ghidra https://ghidra-sre.org/ can be used to detect the FRP bit flag. I say bit Flag, it could be multiple bit flags in a variety of locations. Never under estimate your enemy.
I've used the Emergency Contact select a photo trick, to gain access to all apps, where I've gone straight for the Settings and Build number, tapped it 7 times as per LRMA's instructions but its not unhidden the developer mode and USB debugging options. This could be disabled once FRP is triggered, but its why I say it could be more than one bit flag which is set. Like you see with UEFI bios on some pc motherboards, there could actually be a two or more locations which could be used.
Like I said earlier, having a working device, dumping roms and then triggering FRP would be ideal, but when you dont have any money, it forces you to use your brain as you can't just step out and buy a new device mirrored in every way.
At this stage I dont know if this FRP flag can be undone. It might be like these RaspberryPi One Time Programmable switches as seen here, but I have been able to toggle some of those as well! https://github.com/raspberrypi/docu...asciidoc/computers/raspberry-pi/otp-bits.adoc
I've so far been unsuccessful in finding out if there is an equivalent of vcgencmd otp_dump for Android phones as this could be another way I might be able to find the FRP flag without having to dump the roms.
This is all new to me so I might be looking in the wrong area's as I'm just an unqualified out of work for decades boring old penniless windows programmer so I'm learning as I go along. But you might find what I've put is useful if you fancy a Thanksgiving, Xmas & New Year challenge for a change.

Unlocking Bootloader

Hi,
I have seen this posted a number of times and people keep saying "just Google" or "look at other threads" however I am confused as to what they mean because none of the stuff around seems valid anymore in 2021.
Right now:
There is no modern up to day process to unlock the bootloader that I can find in Google (even if only looking at the last 1 months sites)
I have found so far is telling me to get an unlock bootloader from Huawei which I can't do (they don't offer it any more)
I have found sites telling me to pay for the bootloader code from funkyhuawei, site that no longer offers them, someone posted about "Direct unlock with no code" but didn't go into details on how that is done, and then I found this on rootmygalaxy:
" Update 2021: All the bootloader unlocking methods have been blocked by Huawei. So none of the methods is working currently. Don’t try to unlock Huawei or Honor devices as of now. For full timeline of events read the story below. We will be updating the post once there is a valid way available. "
So, is that basically meaning that Huawei P20 cannot be unlocked; therefore you cannot root it? If it can be unlocked still can someone, please post a link to how because Google is failing to find anything that is, in fact, working or the information being shared isn't clear enough to explain what is possible.
I am trying to just get information as to if I am wasting my time trying to root this phone, or if it is, in fact, possible or not.

BTW - I have seen {Mod edit} however this only works on EMU 9 or lower. If you are EMU 10 you have to roll back, but it appears Huawei have prevented this (hiSuite doesn't offer the options any more).

Okay, this has been fixed - so I am doing the roll-back now. If that works, I will try the URL included in the port above and then report back, so if people want to know what is possible.

Okay ... um.... they need to remote onto your computer and do it.... that is totally unacceptable.
So basically, there is no way that I can see that allows "ME" to unlock the bootloader, and instead you are allowing people to access your computer, so they can do it.

Question What is the current state of unlocking fastboot?

Have decided to rejoin XDA after a while off to see what sort of response I get to this.
A browse of the forum tells me that there is no known way to unlock fastboot, I was wondering what methods had been explored in an attempt to do this?
More specifically there are 2 potential methods I'd like to ask about.
1: I have seen mentioned in a comment here a tool I stumbled across a few months ago while messing around with another device,
edl/README.md at master · bkerler/edl
Inofficial Qualcomm Firehose / Sahara / Streaming / Diag Tools :) - edl/README.md at master · bkerler/edl
github.com
There is one option in particular that I think is of interest,
edl modules oemunlock enable -> Unlocks OEM if partition "config" exists, fastboot oem unlock is still needed afterwards
2: After a quick browse of the disassembled Oppo deeptesting app I can see a number of references to a class that is only accessible via reflection 'android.engineer.OplusEngineerManager'
and it contains a method 'fastbootUnlock'. Has anyone tried to access this class and its methods at all?
Maybe none of these things will be of any use, but before I spend too much time exploring them, I was interested to hear if anyone else had explored these at all? If so what progress was or wasn't made?

A little update for anyone who is interested:
So I have spent a little bit of time this morning seeing what I can do with the 'OplusEngineerManager' class. I made very simple app to see what access I could get to this class. After adding a library to allow the use of reflection to access non sdk classes I was able to get a list methods from the class, but so far have not been successfully invoke any of them, despite there being no exceptions caught.

I took a look at the fastbootUnlock method itself (at /system/framework/oplus-framework.jar) and I believe that even if we could invoke it, it wouldn't work because it uses some sort of token (generated be Oppo?). I might be wrong though, I don't have much experience working with decompiled code, and the code I looked at was Realme one (I guess its same as Oppo).

Its great that someone else is looking at this! I hadn't posted another update as I haven't made a huge amount of progress, and I wasn't sure anybody would be interested.
The fastbootUnlock method returns a boolean and takes 2 parameters, a byte array and an int. From what I can see it is the only method of the OplusEngineerManager class that the deeptesting app calls. It contains 2 calls to the fastbootUnlock method. Once where it calls it with an empty byte array and the int is 1. I was actually able to invoke the method from my test app in this way and got a false return value (rather than just getting null like the other methods I tried to invoke). The second is contained within a method of the deeptesting app that takes a string as its parameter. It then converts this string to a byte array which it passes as the paramter for the fastbootUnlock method along with the int of 1.
Edit:
The second call to fastbootUnlock uses the length of the byte array as the int and not 1. Please forgive me it was late when I wrote this and I was not looking at the source.
Thats about as far as I am with it at the moment, the next task is to find out what that string it passes is exactly, and is it something that needs to be generated by Oppo.
I would imagine the realme framework woukd be similar, if you would like to compare I can provide the full list of methods from the OplusEngineerManager class?

Hey guys, I would be interested in helping you somehow.
I have no prior experience with unlocking a device. (besides actually doing it with the tools provided by anyone else).
But I own an oppo find x3 pro, if you need me to do some testing for you, let me know
Thank you for your reaserch and trying to unlock the fastboot!

Hi, thanks for your reply. At the moment there isn't too nuch to test, but if I do manage to find a way I will need plenty of testers, so thank you

A small update:
I have found that the method in the deep testing app which takes a string and then ends up invoking the reflected fastbootUnlock method is called by a handler associated with one of the app's activities.
The handler gets the string extra from the intent which starts the activity, and then passes that as the parameter when calling the method.
The next problem is that I cannot find anywhere in the deep testing app that starts this activity. I can see as part of, what I believe to be, the normal flow of the deep testing app that an activity in the startup wizard is called, so I wonder if the startup wizard then starts the activity of interest in the deep testing app. This will be the next thing I look into
Edit:
I have looked into this more and it turns out most of this is wrong. The activity is started from within the deeptesting app and not the startup wizard

Great, from my side I tried running the fastbootUnlock method as you did, and got the same result (false). I looked at the logs and there was a selinux denial for finding the engineering service as my app is an untrusted app, so our only way to run the fastbootUnlock method is through the deep testing app I guess.

Great, from my side I tried running the fastbootUnlock method as you did, and got the same result (false).

Do you mind if I see the logs? I have had no such denial that I can see.
How have you enabled access to hidden apis?
Have you used any of the permissions from the deeptesting app?

There are the logs. I enabled hidden apis, yes, didn't add any extra permissions though. By the way, did you use some specific keys for signing the app (platform keys for example)?

I had a closer look at the logs and I can see that sadly I am getting the same SELinux error.
I can't see much of a way around it at the moment.

I have made a thread in general should anyone wish to discuss this further. Most of this is applicable to all Oppo devices and there are people that have looked at this in different ways and found different things out when trying to unlock fastboot on other devices. I think it would be useful to have somewhere to discuss unlocking fastboot on Oppo devices in general.
[DISCUSSION] A thread to collate and share what is known about unlocking fastboot on Oppo devices
Admin: Please move/delete this thread if it is in the wrong place or against the rules. I wanted to create a thread to discuss unlocking fastboot mode on Oppo devices in general, rather than discussing it in terms of any one device in...
