Hi,

I just happened to google how to unlock Nokia 7 Plus' bootloader again and stumbled upon this site:


It was updated today with a free way to generate bootloader unlock keys for Nokia 7 Plus apparently. Now I can't test this myself at the moment (in a week at earliest), but do you think this is legit?

At least I can generate a code apparently, so this part is actually free.

I use my Nokia 7 Plus as primary phone as well, but I guess I'll just risk it :)

However, I can't promise anything here. Hopefully I will get around to it within the coming week.

I tried it yesterday and it work flawlessly.

Just follow the steps on the page, I had no issues unlocking the bootloader.

That being said, I nearly bricked my device when trying to flash Lineage OS onto it (because all TWRP and Lineage OS step by step guides seem to be out of date?), but this guide helped me get back to stock: https://forum.xda-developers.com/t/...m-flash-tool-nokia-7-plus-b2n_sprout.4023961/

Might keep it handy if you are like me :D

Thanks for the useful infos.
I suppose I will unlock my phone in the upcomming months but right now I just factory resetted it and it's working almost nicely.
I really want to unlock and flash a custom rom on my phone, because the stock rom it's buggy and tends to have some performance issues, but right now if I mess with it I can't afford to change the phone so I guess I'll have to wait.

Yeah, the tutorials seem to be a little outdated...

In general, follow this guide here (its from the same person that created the official twrp.me site I believe):


I wasn't sure if I have a OOB or POB device, but I haven't had any issues using both (currently using OOB since I'm pretty sure my Nokia 7 Plus is that old :D)

Secondly, what the instruction somehow failed to mention is how to get the install.zip. It is on their sourceforge page in a subfolder:

This is for the OOB variant, you can replace OOB at the end with POB to get the other files

You can verify, that I'm sending you the right link by following the links from the forum post to download the image to boot from. For example:


Now you can just remove the "twrp-3.4.0-0-B2N_sprout-POB-10.0-20200829.img/download" part of the URL and you get to the folder where all the other images are located. Download the latest "twrp-installer-*.zip" for your device and install it.

This is great, thank you so much! I can also boot from both OOB and POB, will try this out later today :)

EDIT: worked like a charm. Thanks again!

Hi @Znert, did you use TWRP for Android 10 or Android 11?

Another question: can I unlock the bootloader of a Nokia 7+ on Android 10?

Thank you again.
I use the Android 10 version, but I'm not sure what the difference is anyways (it's a bootloader, shouldn't that be OS independent?)

Regarding your second question, yes, I unlocked my bootloader with the latest official stock ROM (so Android 10).

Yes that's what I thought also... Maybe we need to use the Android 11 version to install a Android 11 ROM.
Now I see there is a new version of TWRP 3.5.2 on the official website.
