Source code: https://www.nokia.com/phones/en_int/opensource (version 1.150)
Full OTA: https://www.thecustomdroid.com/nokia-5-4...e-updates/ (version 1.150)

This device is built with the last generation of locked bootloaders with almost no recovery mode.

The only way to unlock the device or at least get root access is by building our own version of the full OTA with patched boot and recovery, disabled verifications, fake update timestamp, and a signed zip file with RSA private and x509 keys found in the source code so we can sideload it into the phone and bypass almost everything.

To be able to start this process from here: https://android.googlesource.com/platfor...t_files.py

I decided to learn android development as it looked simple at first. But now I don't even know how to use python and it seems like I need some general knowledge of different programming languages before getting into the first step.

If you are able to unlock the device yourselves or provide me any kind of help, I would be very thankful

Unlock the bootloader or at least bypass or disabled some of its functions like verity by getting root access which is easily done by patching boot.img or using the source code to at least be able to flash OTA without annoying verifications.

You need to unlock bootloader first before attempting to flash anything custom that includes empty vbmeta for disabling verity

But I have dev and private keys to sign everything out to pass through adb sideload

I think we even have the key that unlocks the bootloader like unlock.bin but since the bootloader is locked it won't even flash the file. We have to go in either through adb or edl

won't make any difference if bootloader isn't unlocked first

if so, then take a look at aboot from within the firmware using the guide @ https://www.hovatek.com/forum/thread-21403.html
it might shed more light as to how or which command one needs to unlock bootloader

Can't find aboot even in the source code and the full ota. I heard aboot.img has different names now maybe that's why

Yesterday my phone received the latest full OTA update v1.300 so I grabbed the link: https://android.googleapis.com/packages/...ab9477.zip

It's the same as 1.150
