Dev-Unlocking 8.0 - Windows Phone 8 Q&A, Help & Troubleshooting

Since the certificate for Dev-Unlocking Windows Phone 8.0 expired in May, has anyone come up with an alternative way to dev-unlock without updating to 8.1?

8.1 is much better bruv it wud be a better idea to just grab the update imo , ainit ?

It's a more complicated matter in this instance. I need to remain on the 8.0 firmware to get 10 working smoothly on the Ativ SE, and I need to unlock it on 8.0 to keep that firmware without spoofing another firmware (which will ruin the chance of me updating to 10).

Aight I assume your phone have an SD card slot, you might be able to get it unlocked via a language pack update ( no hard reset involved) , now the problem here is that I don't know much about how to do this but I'm sure @djamol would be able to help you , check out his posts I think I've seen him talk about this before ,, unfortunately I don't remember much as I've been busy lately , but I'm sure it is possible ,, also I don't know why would having 8.1 update ruin your w10m upgrade? I heard most people are upgrading fine,,, also .. I think there's an interop unlock for w10m itself being released soon as w10m is released

developer unlock to full interop unlock ? possible after Tango ?

I've been running around in circles for hours, is it possible to go from a developer unlock to a full interop unlock -after- having updated to Tango 7.10.8773.98 ? I can load some XAP's, but root tools and wintt fail.
I had to format my PC and lost my backup.
I'm sort of in the same boat as you. I will be going to my local at&t device support center and getting my phone flashed. I'm hoping the guy there can use the oldest rom he has and or give me a copy of it. I'll post results.

no is the short answer if you have already got the newer firmware, the Windows build has little to do with it,although the tango builds do phone home to relock but that can be prevented
dev unlock is not interop unlock, which is needed to access high privileged functions
if you didn't update the firmware but you did let it relock then simply reapply the unlock and then apply the relock prevent xap, but I suspect you have already tried that suggesting you have the new firmware as well

perhaps ATT will flash the older ROM, I doubt it though and I doubt it even less that they would give you a flashable copy
but stranger things have happened so lets (hope) wait and see
Not what I really wanted to hear, but that's about what I figured/expected. I can't imagine going into AT&T & finding someone who had a clue about re-flashing a WP device.

change the device ID to a nokia
goto HKLM system platform
change OEMdevicename to Lumia 900
OemName to NOKIA ( that is case sensitive)
MODeviceName Lumia 900
that will stop the Samsung update notification and also let you use nokia apps
oh before you change them can you post what yours say? im curious about something

[Q] Downgrading from WP 8.1 to 8.0

Hi there, I've been an Android user for a couple of years now and I love tweking, modding, flashing and bricking (well, maybe not bricking, no ) my devices. Last week I also bought a Lumia 720, and I would really like to update to WP 8.1. I found out how to do it, doesn't look difficult.
Anyway, I couldn't find enough information about downgrading: will I be able to do it in case I need to?
Should I use Nokia Care Suit to download my current 8.0 firmware and then flash it back whenever I want to?
And what about warranty? Is it lost when I update to WP 8.1? Is it restored if I downgrade?
Sorry to bother you all, but I'm a real noob about Windows Phone...
You can downgrade with NCS, yes. Downgrade is not officially supported but there's no reason it shouldn't work and several people have reported trouble-free succes already.

I downgraded a 1020 with no issue, my 928 got bricked.... NCS crashed and now the 928 can't turn on. Just be careful is the bottom line.
I downgraded my 521 with ncs after my power button stopped working in 8.1. My power button still didn't work in 8.0 so I went back to 8.1 again. ? at least I can use double tap to wake my phone up or use the camera button.

Trying to get interop-unlocked

Ok, so I unfortunately never unlocked my phone before the official GDR3... But now am wanting to. Does anyone know of a way to roll back to GDR2 on the Ativ S Neo SPH-I800? I realize this is a long-shot, but am really needing a hotspot now, and don't want to pay Sprint for it. Suggestions? Note that I've also updated to 8.1 :/ I realize it was incredibly stupid to not do this stuff before updating.
Edit: note, I did get the diagnoses app before updating to GDR3, though I doubt that will help. Any code I could punch in to get me where the toast would?
I did the same exact thing with my t899m ativ s. I ended up flashing wolfs custom csc using his fake rom. Works perfect. Post in that thread since I'm pretty sure he's gonna have to make the csc file for your phone/sw version.
Only thing I had to do after reset was do the rpc unblock.

You can try to interop-unlock it with wolf's fake rom,
Read here (all the thread) and you'll be able to unlock it
http://forum.xda-developers.com/showthread.php?t=2480510
Unlocking GDR3 you would only need to create Non-Production Errors.txt to your phones documents folder and then you can unlock as with GDR2 (at least on the GT-I8750, I assume this works on your device also). Thread: http://forum.xda-developers.com/showthread.php?t=2573355
Since you are now on 8.1, that does not work anymore. For Ativ S (GT-I8750) there are solutions to unlock 8.1, see here: http://forum.xda-developers.com/showthread.php?t=2735495, but for SPH-I800 I dont know. Are there GDR3 roms around so you could flash it and unlock before updating to 8.1?
'Non-Production Errors.txt' will only interop-unlock a locked phone if it has the old version of Samsung's Diagnosis app installed. The Samsung firmware update that came with retail GDR3 has a new version of Diagnosis without the built-in registry editor.

UPDATE!

I live in turkey. My Cod c464. How do I upload the oreo update? Without Root or something like root
you'll have to keep waiting.. u can try using firmware finder, it doesnt use root, research about it.
but i've read from many users, even if it downloads the updated firmware, it wont install and will just occupy ur storage space
learn where to find the folder and delete the downloaded package, just in case if u try it...

Thank you. It's so complicated. Have you ever tried the Orero update? Better than the old versions?

I tried the Oreo update and I live in Turkey too. EMUI 8 is way better than EMUI 5, it's just that you can't install viper4android on EMUI 8 yet, so I don't use it. If you really want to try the Oreo I can help you with that.

The website that you get your unlock code from is no longer working. There are some people that got their code from huawei via e-mail but I don't know how they did it. Can't help you with that either sorry
I contacted them via their contact form asking for an unlock code to unlock my FRP.
You need to tell them your
- Model number
- IMEI1
- IMEI2
- Serial number
- Product ID
Response was very fast but they double checked if I really want to do this and told me about lost warranty and so on which stalled the process a bit.
To get your Bootloader unlocked you can tweet Huawei UK on Twitter and they'll reply to you.
Just mention them in a tweet saying that you need your unlock code after that they'll follow you back and DM you then you give them your information.
It took about 3 days to get mine.

So we can hope for the official bootloader soon.

Finally some good news!!! https://nokiapoweruser.com/hmd-announces-bootloader-unlock-for-nokia-8/
I doubt it. It's over a year old now and not likely to be the focus of their efforts, and those HMD guys seem like wankers anyway, giving us a Sophie's choice instead of bootloader unlock for all of their phones.
well, someone already tried to do the process in his nokia 5 ??
I tried but at the time of installing the apk I got an error, I think it's because I'm in the 7.1.2 firmware
it would be a matter of trying to update to 8.1 and see if it is feasible to unlock the bootloader

It's only for Nokia 8 for now. Why would you even try to do that without reading about it?
