Hi,
Flashing a ROM without unlocking the bootloader isn't possible.

What do you mean ?
It's the case for all ROMs and all phones

i mean instead of flashing an android rom, to flash a linux rom.
but when you say its the same trouble with bootloader unlocking, then its senseless

Yes look at the roms own pages, all have their info about this.
Only stock custom roms are installable, Roms with custom kernels need you to unlock BL.

[Q] Custom ROM + Fully Rooted.

Hey,
I would like some help from you guys.
It's been a while since I put a custom rom on my previous phone.
So if possible I would like a comprehensive explanation.
Right now I have Emui 3.1 installed on my P7 L10.
I would like to install a custom rom but I'm not sure I got my bootloader unlocked.
If possible I would like to know how to unlock the bootloader and install a custom rom with full root.
I did some research already on the internet but all the explanations are so short.
The rom I want to have installed on my P7 L10 is the following:

I hope someone want to help me with this.

I'm afraid you will not be able to install that rom, since it is meant for emui 3.0 not 3.1
The only working custom ROM for lollipop is the Miui rom and that's it. All the other Roms are based on kitkat.

Isn't it possible to downgrade from 3.1 to 3.0?
And even if my bootloader is locked to 2.3??

It is possible and there are many guides out there which tell you how to unlock your bootloader. Just don't try to flash that rom while on lollipop.

I know, but I think the guides are not detailed enough of the download links are not working.
Just ignore that it says b805, because it works with all of lollipop firmwares.

Are Android One bootloaders unlocked already?

Hello everyone. I just wanted to know if Android One First-Gen phones have unlocked bootloaders cos I am going to root my QMobile A1 and install a recovery on it to flash a Nougat ROM later on. If it's locked then how can I unlock it? Thanks for helping!

International version - Should I flash official china ROM and relock the bootloader?

Hi all!
Loving my new device!
I bought it from Gearbest and it's the International version that came with an unlocked bootloader and the Official Global ROM installed (no idea how they unlocked the bootloader).
Just after I booted it for the first time I got the official update to MIUI 10 and everything went perfectly.
My question is: should I reflash the official China ROM and relock the bootloader just to be able to unlock it again on my own? What's the advantage of doing it since it's already unlocked and with an official ROM?
Is it safer? Can I be in trouble in the future if I don't do it?
Sorry for asking this basic question, but this is a new ecosystem for me.
Cheers!

A good question, and yes, if you want to have control of your phone, this is a good idea, but you will wait btw 15-20 days
