I am currently on A2017U B29 Marshmallow 6.0.1 full Stock. I did not upgrade so far to Nougat, in fear of ZTE locking the bootloader, etc.
In future, I want to fully unlock the bootloader, install TWRP, and load Lineage OS.
If I upgrade my phone to the latest Stock Nougat, will I still be able to do the move to lineage - did ZTE mess up the bootloader any way in Nougat?
From what I read here, it is safe to do so and that I can always unlock the bootloader no matter what - but I need a quick confirmation.
Thanks.

You can always downgrade... you just have to get the Marshmallow update zip and install it with mifavor. totally legal and stuff
Hi there, im currently on the leaked oreo beta on my A2017G but since this month there should be the official oreo out i wish to rollback to stock. Do i just need to flash latest rom on it? Do i need to relock the bootloader and remove twrp to get new ota updates?

I bought an S8 with oreo. With oreo I can't use fingerprint to open apps without a secure lockscreen.
Can I downgrade my phone to nougat? How? Will I lose the warranty or have similar problems?

I have a G950F unrooted and with stock Pie. Is it possible to downgrade to Oreo ? Of course I'm keen to root and unblock the booloader

Depending on what firmware version you are on. Due to bootloader(binary) versions increasing you cannot downgrade to a previous version, only a previous version with the same bootloader number or a higher version.
Basically if you on version 5 (bootloader/binary) you won't be able to downgrade to Oreo.
The only way is if there is a custom rom that has an Oreo favour to it.
You can still root on pie.
