[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.

Force install Windows 10 Mobile

Hi everyone,
I have a HTC 8x (AT&T) with 8GB of storage. I was waiting patiently for the upgrade to Windows 10, but from the latest news I have come to understand that there is no such thing as a upgrade support to win10 for this particular phone.
Now I am trying to find some useful instructions here on how to upgrade this phone even though it is not supported on the list.
My question is: Has anyone tried this un-official way of upgrading this phone to win10 mobile, and if yes then how do you get further updates?
Greetings!

Unbrick P10 Selfie

Hi everyone, I need your help, I just bricked my CellPhone Huawei P10 Selfie.
BUILD NUMBER: BAC-L03C25B153
MODEL NUMBER: BAC-L03
PRODUCT ID: 26401324
SERIAL NUMBER: 6FCDU17929002623
I was trying to install oreo, I unlocked bootloader with any problem, but when I try to install TWRP it bricked.
When it try to boot it stop in the window that said Your device has been unlocked and can't be trusted to learn mor visit:.... and has a message your device is booting now... after a few minutes it automatic restart.
I can't use the bootloader, because I can't access to USB debuggin, eRecobery doesn't download, and when I try to install from SD Card with dload folder in root directory whith the os downloaded from hear "pro-teammt /firmware-database/ " using the vol+, vol- and on button, it start the process and when it has about 5% stop and return a message: software install failed.
What can I do?
Regards.

The P10 Selfie isn't a P10. This forum is just for the P10 VTR model.
You own a BAC which is completely different to the P10, and I really don't know why Huawei sells this in some regions as a P10 Selfie - it even doesn't look like a P10.
So, wrong forum for you - this is correct.

After see an image of Nova 2 plus I see they are very similar, I'm thinking if they are the same? Well I just unbricked the phone I will start a guide in the form you recommended.

Bootloader unlock / root / LineageOs on stock p8 Lite 2017 emui 8

Hello,
I've been searching for days for a way to unlock bootloader/root my p8 lite 2017 (PRA-LX1 with EMUI 8), I've tried a lot of things, read of lot of topics, and at this point, I don't know if it is even possible.
I read that it is possible to root my phone by downgrading it to android 5 so I tried, but I think I need to have android 6 since nothing really happens. I put the update files in the dload directory, my phone starts and shows the update screen, then it starts and nothing has changed.
I tried to reset to factory settings, hoping it would go back to a previous android version but it's still on EMUI 8.
I tried that dc unlock software, but since my phone uses android 8, it seems that the guy want 25€ to give the code...
I want to install Lineage Os and root my phone, that's all. Is there a way to perform that for me or do I have to forget the idea ?
Thank you for your time.

it seems my topic is not in the proper forum, sorry for the mistake...

All I found is that you should stay below B374 - Emui and Android 8.0.0 are fine ...
use dcUnlocker from playstore - pay a few Euro / $$ and you'll receive an unlock code for use in adb fastboot
