Soory i am so late to answer but kernel codes for nokia 5.3 are now available on their official site....this can b3 used to unlock the bootloader

Hi, can you post a link and more info for this? I've seen that there is the GPL source code for some phones on the official nokia website, but I have no idea on how that can be used to unlock the bootloader. Maybe you can link to some guide available online?

I also need it to unlock the bootloader, and root, for the Nokia 2.2 (for which there is no source code on nokia's site, but maybe other phones' code could be useful instead).

Hi guys, doing some research

when trying

fastboot oem unlock


you'll get

FAILED (remote: 'Failed to unlock, decrypt failed!')

because you need first to do

fastboot flash unlock unlock.key

so you can then unlock the bootloader

fastboot oem unlock

So the main thing is to generate that key. Nokia officially unlocks the nokia 8 but not the 5.3. I'll start checking their kernel which is freely available at
http://nokiaphones-opensource.azureedge.net/download/phones/Nokia5.3_V1.120.tar.bz2 as @opasx said

A good place to start can be is the fact we know that the unlocking mechanism will look on the unlock partition

I'm on that now

good luck

I don't think there is really a "unlock" partition it is probably just a file system that is made by the bootloader , checking the kernel source code is going to be useless as the unlocking mechanism is controlled by the bootloader , maybe using QFIL in 9008 mode and then flashing a modded devinfo (Same thing used in the Lenovo tab 4 10 , due to the bootloader unlocking option being greyed out)
