What about encryption:​

Flashable zip to enable encryption is in this post
How to enable encryption

I posted this in Telegram Channel :​

"One important thing is the encryption thing and I know the majority voted for it to be included but I'm truly sorry to go against the majority as encryption will make my development work much slower and there will be always a risk to lose data from my side which I can't afford. So no force encryption in arrow-12.1 and it won't work unless it was forced at boot(changed in fstab).​

​

However I'm planning to provide a flashable file that will enable encryption but it need further testing to make sure everything is working correctly.​

​

I hope everyone understand my decision and sorry again if you don't agree with it."​

​

It is already mentioned in the OP that , "samsung proprietary apps wont work" in any of the AOSP ROMs. That includes, Samsung Camera also which can not be ported to AOSP ROMs.

N960N can use this rom

 

[Aadil321]

Been using this rom for about 4 days now and I must say it's just perfect. So far I haven't encounter any bugs, the performance is great and the ui is stunning. Highly recommend it. Device - Note 9

 

[king1990]

Yes. make sure to flash your stock vendor if coming from noble rom

My apologies if this is the wrong forum thread. I saw the article below.

Samsung Galaxy S9 and Galaxy Note 9 can now run Android 12, unofficially

The Samsung Galaxy S9, S9 Plus, and Galaxy Note 9 have received unofficial ports of Android 12 through the ArrowOS custom ROM. Read on!

www.xda-developers.com

I have a "Verizon" Note 9. Is it possible for me to upgrade to Android 12 or is my phone locked? My understanding is that Verizon locks their Samsung phones.

 

[dyolal2]

I tried to install it, but it enters the download location and stays, can you help?

 

[sherry9oct]

I was installing this rom and was coming from noble rom. I did not do a proper wipe after which now the phone is dead. I am not seeing any thing. When I press power button i dont see any thing. Only force restart works (volume down and power button) but after that nothing happens. Any idea how to fix.

you need to unlock the bootloader first. I don't know if this is possible.

Flash your stock vendor. I will add vendors to the main post later today.

flash any oneui 2.5 then boot to system / reboot to twrp and follow the instructions

 

[BinukaSL]

Works perfectly! I feel like battery life also better than oneUI <3 Thank you for the great effort!
