Nokia 5.3 bootloader unlock

MadMaxFromKiev

Hello guys, let's talk about all of available bootloader unlock methods?

I tried standard ones from Nokia 4.2, Nokia 1 Plus and Nokia 7.2 - it didn't work, just say me "failed. Auth. needed". Maybe someone know about testpoints or smthg like that?

It will be great, if we found bootloader unlock method.

Still no idea?😕

I really do hope that someone finds a method for this. I really miss Havoc OS😟

Yeah, I'm really fed up with their delayed updates.

I managed to unlock my bootloader on Nokia 5.3

Just can't remember how

I think you're trolling

Then you definitely haven't unlocked the bootloader.

Yeah so am I. I've practically been spamming the check for updates button since March with no avail😅

I read somewhere HMD was out of the Android Developer Program and had to get back in, thus resulting in delays. But to be honest I wonder 1 thing: how?!

Hi guys, doing some research

when trying

fastboot oem unlock

you'll git

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

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

There will not be a unlock partition afaik. It just virtually hosts the file to pass it for decryption and verification against the public key.

I wish you a lot of luck. If it works or not doesn't matter. It's about the fact that at least some one is trying😁

Unlock key is tied to your IMEI

SnowLily

Correct. But I doubt HMD Global wouldn't take extra measures to make sure it isn't that simple. Afaik, just for advice, I think the flash file for our devices contain several images that make up the entire system. I don't have a ton of knowledge about this specifically, but maybe a flash file could be used to get more info on what is needed to make that specific key/unlock the bootloader. I also read somewhere on XDA that someone said the kernel source(which is openly published) can be convenient. Anyhow, good luck 😁

Sorry for the double about the Nokia kernel source. Only read through the posts twice just now and noticed someone else already said that😅

cool, thx

we need to find out how that happens to generate our unlock key, i found sites claiming to send you a valid unlock key, off course, paid

if anyone has any info about this, it'll be awesome, the idea is to build an unlock generator from your imei

if someone in HMD/Nokia hears this, please, help.

as a free software dev i think every one has the right to fully use the hardware we fully paid of. what's the point of not allowing to unlock the bootloader?

thx everyone here

if anyone has a nokia 8 imei we can get the unlock image from nokia [ https://www.nokia.com/phones/en_int/bootloader ] and analyze it, maybe we can find something useful

There is no way whatsoever to generate an unlock key for the Nokia 5.3 and any other new Nokia devices. Only old ones were supported.
