Interop-Unlocking is OS-related right ? The issue is to deploy it on some device, so why not apply it on the ROM itself and then flash this ROM to the device ?!
Most of us know that flashing our Nokia Lumia just needs Data Package Manager (or NaviFirm) to download a new ROM (to get the latest version, your country, operator variant...) and Product Support Tool For Store to flash it.
So my question is can't we apply the Interop-Unlock on these files and then flash them to the phone ?

from what i know my friend is that interop is phone side now way to do that like this ,maybe rom with a xap(exploit) onboard but it's good people come with ideas
more ideas more we can do.

Afaik you need an unlocked bootloader to install a custom rom
our bootloaders aren't unlocked
These ROMs are most likely signed. The phone checks most likely for a valid signature upon install of those ROM thus preventing us from Manipulation ist contents.

That was an idea... and I've seen it nowhere so I just wanted to bring it to you (because I have absolutely no idea of how to do it ).
Is there no way to remove the sig from the ROM, then edit the ROM with interop unlock and then sign the thing again with the same signature you remove?
The problem is re-signing it. Only Nokia has the means to sign a file in a way that the phone will accept it, and it's likely through a unique key generated by Nokia.

There is no way to get that unique key? Or to know how they specifically sign the ROM's?
can u tell me if sth is going to happen soon? 5 best devs got 5 fckn Lumias
and we got 2 months already passed i know that a human person has to eat ,**** and other stuff but lumia scene is currently dead for that moment .NOTHING HAPPENS ONLY **** IDEAS .

I believe that requires a level of reverse engineering that I'm not sure has ever been done on a windows phone. HTC phones are able to flash a custom ROM by bypassing the need for a signed key, rather than signing it through HTC's way. If developers focused on signing them rather than bypassing the signing development on phones would take ten times longer.

I see. And on Nokia phones, can't we find a way to bypass the sig check as well? Or something similar. I remember SSPL from my HD Mini. If I remember correctly, it didn't do anything to the bootloader, it just somehow managed to have a correct check (or maybe no check at all) for the sig and then I could flash whatever I wanted. Is SSPL for Lumia 800 an option?

All I've heard about Nokia Windows Phones is that they're harder to crack and bypass than HTC and Samsung's phones; not entirely sure what makes one harder over the other.
We can modify Symbian ROMs and flash them in Phoenix. Has anyone checked that WP7 ROMs wouldn't work the same way?
I flashed a new Lumia ROM in Phoenix and the files were deployed in the same way that they deploy on Nokia Symbian devices.
So, ... maybe the Symbian firmware tools would work (with slight modification?).
Lumia bootloader will block any unsigned rom, it doesn't work in a symbian way.

I'm pretty sure Symbian bootloader is locked down too and requires signed ROMs (at least the core needs to be signed, maybe not the UDA).
I think someone found a way around it which is why we have custom ROMs on Symbian. Do you think same thing could be done on WP7?

Maybe we could ask one of the Symbian devs to help us? To take a look?
I see post with info like 'the bootloader checks to see if the rom is signed correctly' and I agree to that because I have thought about it too and came to the same conclusion. It's just logical to assume since deploying cabs and using resources (registry editing and other high privileged actions) are so well protected by MS and Nokia. (Actually this holds for other OEMs as well these days, for example HTC; v2 drivers are as well protected as the ones of Nokia and therefore as of today not providing us with the exploits earlier versions deliverd to unlock our phones.)
We could blame them for that but in fact i think they are doing a very good job in keeping things safe. That's why I appreciate for example why Heatcliff is releasing the next Root Tools (unfortunately but understandably for already Interop Unlocked phones) with a meganism that allows the user to decide which apps may have the permissions they require and which don't (to prevent malware).
Going back to the roms, has anyone actually tried to alter a ROM with the required registry settings to enable Interop Unlock in the ROM itself? I believe it's only one key that's important: "\Software\Microsoft\DeviceReg\Install\MaxUnsignedApp" that needs to be set to a value of 300 or higer for the phone to be interop unlocked (AppHub and Chevron Labs set this value to 10, AppHub student to 3). There are also a few values to keep it from relocking, but MaxUnsignedApp is the key key ;-). See http://wiki.windowsphonehacker.com/wiki/Interop_unlock.
The reason why I ask this is because I haven't seen any tools around here that allow the ROM files to be editted. I know most of them are just zip files (rename them and you can look inside), but then you end up with other files that i do not see how to edit.
My point is: As long as we have not tried this approach we cannot confirm our (I admit most likely true hypothesis that the altered rom will be rejected by means of invalid signature).
Also, take note that there are two ways of flashing a rom that we know of:
* Refurbished flashing, which requires the phone to be 'alive', and
* Recovery flashing, which first gets the phone's bootloader in some sort of 'download' mode
This last recovery mode might seem the best way (as in least protected) to start with.
Note: I'm not an expert in this like HeathCliff and GoodDayToDie, I'm just trying to offer some ideas and give a summary for what is my understanding of the current situation by reading this forums.
Seems a good idea However, I doubt if the phone would accept the altered ROM, not mentioning HOW are we going to change it? My guess: the phone makes sort of hash from the ROM-file and if it's not allright, it rejects. Altering the registry key, would also alter the hash-code. (Or maybe it's just not working that way but I give the key to uncrackable ROM's). Whatever, just posting what comes to my mind...
I have an idea - we can install updates from cab. Update cab contains some new cabs and inside them we can find rgu files.
And here's my idea -> add registry settings for interop to the rgu and prepare a new cab with update.
Has anyone tried it yet?
I bought a used nokia lumia 800 yesterday and everything goes fine!!! Except one thing!
When i go to marketplace and try to download something it says that something goes wrong and i have to restart marketplace or mobile!
I have done it but nothing...
The error code is 805A0190!
I cannot solve it after many hours trying...
The mobile has bootloader and has some programs from the forum (WP7 tools, WM device center, winTT, file deployer, Ds supertool which i dont know and understand anyone of these programs) and i think the problem has to do with that,
I ask for help if anyone knows...Thanks!!

There is apparently a problem with the Marketplace at the moment (something to do with certificates) so maybe it's to do with that?

I had this issue using a custom cooked rom that used ultrashots full unlock and flashed it onto my lumia. Everything works ok as long I did not update to Tango.
After the helpful advice from ultrashot to change a file in the unlock-package and recook and reflash averything is ok. So your lumia one of the rare one's with a full unlock, cause you have WP7 Root Tools in it and functional.
this is what ultrashot recommends to change when cooking a full unlocked tango rom and it works in my case
Code:
Hi.
You must use uZMF_Serv.dll from Dynamics 1.21. I am not providing any packages - just get my rom and unpack it. Original file will lead to working Marketplace but not working XBLive games.
Next unlock won't need this patch.
If you never cooked a rom, send me a pm, I'll share my own. Then you'll have to flash it onto your device.
2. way, but not tested:
I'll never tried if it is possible to copy the file in question onto the correct folder, but I doubt, that it remains a reboot. If you do not know, what all this is for: sell your phone here to someone needing the unlockable version and buy a not unlockable phone, so your problem is solved, because it is caused by the unlock.
(I'll guess that the price earning while selling a so called qualcom-bootloader nokia lumia is higher then the falling prices for new lumias with dload-bootloader)

Thats the reason, because I advised you to sell it.
If you don't know how to flash your lumia to another custom rom or to a stock rom, you should read here or in the developer-forum . If you feeling able to do the mentioned steps to flash (and keeping in mind, that there is a ability to brick the phone, if you fail) I can support you with a functional rom, that remains the unlocked status of your phone. Theres no other way I see to overcome your error with marketplace as flashing another rom, cause there is a wrong library in the rom, your seller flashed before he sells the phone.

I had an android phone before that and i know about flashing roms and such things (basics) but with the new one wich has windows im not experienced ...
If u can plz show me one good rom for flashing and the ways...
thanks
Hi,
All,you need to know is written in the threads I mentioned in my last post. I prefer the Linux dd method, other like the Nokia care suite method, I think it depends on your Linux skills, which U use If you do not need the unlock, use navifirm to download a stock rom, you can open the largest .esco file with a unzipper and use the image file in it as your flash rom. Here at xda are several manuals and howto's about.
If you like to remain unlock, use some of the custom roms in the lumia 800 dev thread here at xda.

1. Looking at the Magisk guide, It says i need to flash vbmeta. Do I just use the stock version?
2. Do I need to do anything with vendor boot?
3. WIll this work without TWRP, as I am running android 12?
4. Is TWRP stable enough? I know it doesn't support 12, but would it still work?
1. Yes
2. No
3. Don't know, I don't use twrp.
4. Same as 3.
3. Yes, Rooting and Custom Recovery is 2 different situations.
4. Yes, if there's official build for ur device.
And again, pls consider to find out more before what u wanna do before take any further actions, since I think u r not yet clear about what u r doing!
I agree with the above member, please read, research, understand what you're about to attempt and do those again before trying any modifications on your device.

Problem with encrypted storage applies only to TWRP on Android 12
But for installing Magisk you don't need TWRP at all. Get informed about patching the boot img from Magisk app and flashing it through Fastboot - you see, there is no word about flashing anything through TWRP, hence no problem with Magisk on A12

If TWRP would boot (IDK, I did not want to upgrade to A12), you could then even use TWRP (for flashing something) but instead of putting the zip you want to flash to Internal memory, you would need to put it to OTG USB stick or to the SD card that you insert to the SIM2 slot.
Those storages are not encrypted, hence no problem for TWRP to read them

Huh, nice to know about the external storage. Sucks that I have both sim trays occupied right now, cause booting from an sd card is probably an infinitely better solution for right now.

I don't say that you boot from SD card. Just that you copy the zip file you want to flash in TWRP to SD card (or to OTG stick) - then you boot to TWRP, select SD card or mount and select OTG as your storage, then browse to find the zip file there and flash it

Find the subforum on XDA for your Nokia model and read and ask there. Unlocking BL, issues with TWRP and many other things are specific/different for different vendors, and in some cases even phone models and ROM versions
This is Xiaomi Mi 11 Lite 5G subforum and eg I never had a Nokia phone (wrong: I did have but ages ago when Nokia smartphones had Symbion OS, not Android) hence it would be totally meaningless to advice you anything about Nokia
Thanks for enlightening me, kindly drop me any links for Nokia forums about rooting and bls. Because am really need that knowledge. I can't forget say am totally fresh...... sorry.
Another thing which is not the same topic: if Nokia and everyone told me that my Nokia x10's bootloader can't be unlocked plus the device can't be rooted. Is it all false because there is some company called "MKOPA" this company provides these kind of phones on loan and Incase you run out of credit/payment expires the phone will automatically be locked by mkopa's app which is preinstalled in the device's software on start. Why am saying all of this is because I believe : If some unofficial company can modify the device's default software builds and rebuild it with their billing and auto lock software it means they are eventually able to unlock the bootloader because am sure there is no way they can install custom files if the device can't be unlocked.
Sorry for my poor English,am not good at it. And kindly help me with that info

Ah, that clears it up a bit more for me. So I can still use it, just not install it. Good to know.
Hi, i tried to install a custom rom in my device (y6 2018 ATU L21) and an error ocurred due to my ****ty usb cable, so now im in a big trouble because the phone is bricked.
I backup some partitions before the accident such as kernel, ramdisk but guess what, the most important (system.img) is corrupted and i can't do anything.
The phone boots and shows huawei logo and then black screen forever, i can't access TWRP nor Erecovery, im completly stuck.
I searched on "Huawei Firmware Finder" but any of the ROMs for ATUL21 works (some of them have missing partitions) so now i only depend on the community, if there is any good person that has this phone and wants to help me by sharing the partitions to me i will appreciate such act of generosity, if you want to help me you can follow those steps (Need to be root):
https://forum.xda-developers.com/t/guide-twrp-backup-current-partitions.3853831/
If you have any stock rom that works for this model im glad to accept it .
Have a good day.
I think I have this for you:
ATU-L21 BACKUP
Good luck!

which tool do i use to write this file
Hello, it's been a while since the post but I still need your help. I have the same problem as describe. I downloaded the file from the nice man. Tried to flash it with fastboot but the phone still has the same problem. maybe you can solve your problem and can help me.
I only have access to fastboot because the rest doesn't work. maybe you also have a custom ROM that works on the device, which doesn't necessarily have to be original software.
Thanks in advance

Hi, this is what i have done to recover the phone. First, there is one mistake that i made and it was trying to flash the files from fastboot, you can't do that because the phone is bricked, instead you need to download the firmware from "Huawei Firmware Finder" and then you need to dissasemble your phone to press the test point. look at this video for reference huawei test point once your PC is going to recognize your device as 'COM' on the device manager, and then you need to use a tool to flash the firmware, i can't share with you the tool since i have switched to Linux distro and i don't use Windows anymore. But if you were smart enough to flash your phone i think with a little bit of search you are gonna find.
Good Luck and have a good day.
Hello thanks for the answer, I have already downloaded stock roms from 2 different sites, both are the same.There are many subfolders in the file but after a long search you can find some .app files right? What should I do with the file exactly? Flash this directly? If so, do you happen to remember the name? Or did you extract the various files from this file, such as "Boot" or something else?
Hello out there,
it might be an easy question for some of you, so please be so kind and help me out: I highly appreciate your answers.

The Samsung Bootloader, which can't be changed due to the burning of the eFuse (yet I do not understand, why one can't use the same method of digitally signing an own bootloader and load it onto the flash without burning the eFuse) boots from a certain file on the flash, which should be Linux-Standard /boot/vmlinuz.
Why can't one backup the whole flash with Samsung Tools and install an own Linux System to boot from?
I now know that the kernel protection is based on a google development, where several virtual machines are loaded and one of those is then the Android System and Kernel, with a Platform where the Apps can be started from (Dalvik) and this virtual machine can be checked for manipulations - so to speak: Software protection = of no use for me or my choice to implement or program my own version of such a protection, but it has nothing to do with a hardware based (knox) protection. Is this correct?
(I do not want to blow the fuse, but use a custom rom. Any solution for this?)

I could analyse the open source code of Android and maybe able to initialize an update process, which might replace the whole file system, but doing so might be a bit dangerous if you don't know what you're doing.
Thanks for answering.

You have already received an answer in your previous threads.
So I don't understand why you keep asking the same thing.
Let me specify my question:
I asked the question in relation to a customization of the bootloader, but I didn't ask it in relation to probably existing Tools, maybe from Samsung (I don't know), which might backup the flash and may be able to put something onto the flash or is this not possible? Why should I change the bootloader (and blow the fuse) if I have all the functionality I need already on the phone? - That's the question.
I've heared something about "download mode" where you can communicate with the smartphone and I've watched a custom rom installation.
I think the installed bootloader is able to backup and restore. But will installation of a custom rom do anything that isn't reversible (like blowing the fuse)?
Or is it fully reversible if I some day re-install the backup I made prior to installing the custom rom?
Is it possible to directly mount the flash under Linux?
Is the bootloader itself directly in the knox-chip? How should the chip otherwise recognise that the bootloader changed?
(a brief overview would be nice)
As you can see: I am very careful and I don't want to do anything wrong, which I'd definitely repent later on. "Just go ahead" without careful planning is not my style. That's the reason why I want to know everything before I start.
I appreciate every answer.
