Hi, I’ve just bought a refurbished OnPlus Nord AC2003 and I was wondering if there’s some specific check to perform before attempting to install eos. The actual SW isAC2003_11_F. 24on Android 12. Thank you, Matteo
Regain your privacy! Adopt /e/OS the deGoogled mobile OS and online services
On the install page Install /e/OS on a OnePlus Nord - “avicii”
we see
Tip: Before installing /e/OS on the OnePlus Nord avicii for the first time, install the latest stock OS version 12 build on the device
You could perhaps check with Oxygen updater, https://oxygenupdater.com/, that you have “latest” to be more sure.
a16 official is expected available but the previous (recent, new) version was withdrawn. A new a16 should be available very soon.

Thank you for your kind suggestions. How do I fall into “official” instead of community build? Simply downloading the official build?
Be aware that it may take a long time before an OTA - upgrade will be available for the A14 based official version. Since most devices were sold with A12 on it.
Maybe a good idea to follow this thread for news on the 3.7.2 update:
I guess ideally you would choose early which of the Different Build Types you would opt for. If you change your mind later, realistically you would fresh install from the other build channel with Format data.
Thank you for replying, but isn’t 3.7.2 official already with A16 for OnePlus Nord?
Here it is declared A16 official:
So it was declared, withdrawn and now you have to check availability from the actual download links in Post #3 … oh, and from the weekly-updates link
Status: To be released
- ETA: 27 April
Done with 3.1.1 Official (3.7.2 ETA has been moved to next week)! A couple of infos missing in the tutorial: OnePlus Nord Avicii, by default, sets the usb connection to “charge mode” only, for this reason it’s necessary to force MTP transfer to have the phone detected. Moreover it’s better to use GIT bash installed version and not the portable one, since with portable there is no “open here” command on right click (clearly on windows). Now one last question: should I relock the bootloader? Or is it everything already set for future OTA? Thank you, Matteo.
Well locking bootloader does not appear in the install page … If locking was possible it is expected to show on install page
Regarding OTA, please observe how a14 was a one off build. Those who have installed it have had zero updates since August 2025.
If you avoid setting up too thoroughly then, I suggest, you could fresh install to a16 later.
I missed the information. Frankly speaking sometimes the news about version upgrade are a bit confusing. So what should I do? Reflash with A12 to wait for official OTA to A16?
Imho to go back to a12 and subject yourself to OTA Upgrade to a16 seems a little perverse. 
If there is no safety update on A14 since last summer and considering that the phone is for my wife, OTA updates are a must and recent security patches too. Am I going to encounter issues rolling back to A12?
Don’t know if you already made a move but I’ve updated my A14 install to A16 using sideload without issues; Off course erasing the data but I had no Wifi-issues like other users.
Since you are running A14 already, I think it won’t infect you as well..
I have the 3.7 image still on my laptop so I can share it with you. Without any waranty, of course. 
Version 3.7.3-a16 is now available for download.
It is possible to install this one over 3.1.1-a14 without triggering a factory reset if you download the correct non-IMG zip-file (just take the same download link only strip the 'IMG-'part) and sideload it from recovery.
