Can someone suggest a good Android Nougat rom?

I've tried a few Oreo roms and have the same issue with all of them - no deep sleep, reboots, screen sometimes wont turn on etc. I'm going to wait for it to become stable.
What's a good, stable N rom to try? LineageOS will encrypt the phone so I want to pick something else maybe something based on it? What are some good stable rom+kernel options? I'm on Fi also.

Stock 7.1.1 is best. Lineage 14.1 is second. Resurrection Remix 7.1.2 is third
I've been using AICP 12.1 (7.1.2 Nougat) with EX Kernel with no issues. I then upgraded to AICP 13.1 (8.1.0). No reboots on AICP Oreo. I haven't noticed an issue with deep sleep. But, AICP 12.1 is very stable. Good luck on your search!
Edit: I haven't been successful with getting EX Kernel to work with AICP Oreo. I've been running stock AICP Oreo.

This x100, Pure Nexus and others were great, but kept coming back to Stock + Xposed
I think Pure Nexus is the best. I use it with Franco Kernel and get pretty good SOT and Standby.
BT and wifi on(all time)
No problem with my watch(connected all time)
With Xposed and V4A & greenify
RR 8.1 is best ROM for me
Stock 7.1.1 ,debloated,Xposed, magisk 16, gravitybox, ElementalX noop 1024 deep black, viper4droid, adaway, iYTBP, 1080x1920 on 420
Try Nitrogen OS Oreo rom. Great battery life.
I still see (on Oreo) that my phone doesn't go into deep sleep. Going to try latest builds of Nitrogen and RR with newest ElementalX.
Nitro rom. Love it

Best cutom ROMs for Santoni

Hi I just got a new Redmi 4x and finally managed to unlock it. What Custom ROMs are best in terms of battery life and stability? Oreo or otherwise?
I think best oreo roms are AOSP Extended 5.3 and Nitrogen OS
I'm aware of the latest Oreo roms and I know recently Xiaomi has released the source code for the santoni phone but still no rom is perfect, specially the Oreo ones, so I'm looking for the closest aosp/stock experience I can get with full compatibility, I think a nougat based rom will do fine but wich one?
I'm planning to install a rom, install greenify, have a good battery life, have more free space and still have full camera, gps and other compatibility with no issues.
Wich rom could you recommend me?
Thanks in advance.

Lineage is not updated. Use latest ROMs like Nos and pe
I had this same question when I bought my Redmi 4X.
I tried a bunch of the custom roms available and now I can say that the best is 8.1.0 Nitrogen OS
It's my daily driver and I have no complains about it
Xiaomi.eu rom
I tried every rom on nougat and oreo roms, and can guarantee that this build of Lineageos 14.1 is the fastest and battery also good, using that with nethunter kernel with enabled autosmp and it gives me 3 days of usage with 7-9 hours of screen usage

Oreo roms seems a lot buggy and not smooth as 7.1.2 roms, amd in 7.1.2 roms i prefer this
Link to kernel - https://yadi.sk/d/wGkzaIcp3U6gZv
Pixel experience
xiaomi.eu is by far more stable one.
In Oreo there a not 100% good roms yet, still on permissive SElinux.
And aosp Nougat based roms.. tried RR/AEX/LOS/crdroid and they are about perfect(rr is my prefered)
Go fr RR NOUGAT. No complaints here

Can't use Bluetooth and can't take screenshot

Sorry I'm still new here. I have a problem using the final resurrection remix in xiaomi redmi 4a. I can't use bluetooth, and can't take screenshots. There is always a Lineage OS pop up stopped working.
Please help me.
That Rom is kinda buggy. If you want another 8.0 or 9.0 rom, i recommend you havoc os or pixel experience or even aosp extended. Those are the best

nice
thank you bro
Gonna try this one as well. Devs have flooded some great roms recently. thanks to all.
Thank you for this rom, I think is the best rom posted recently.
Just one thing, and sorry for the noob question and my english, I feel that GSI roms are more faster than this device specific roms, I have the vendor partition, so, should I flash treble zip in vendor first?

Any trip reports on battery standby drain and screen on time?
Phone Call Audio
I installed this ROM and loved it (I've used RR in the past).
Everything worked fine but for one major thing: while I can place and receive calls I cannot hear or be heard on said calls.
From what I've read this is likely because I have the wrong modem installed, but I cannot for the life of me determine which I should be using, so:
if I have U variant, what bootstack and modem should I flash? Any help truly appreciated!

If you have the U model, you need the universal bootstack and the U modem

I have a U variant and I used

and

from https://androidfilehost.com/?w=files&flid=270519
I am able to hear and be heard on calls with those and this rom.
Thanks for your work, raystef66!

I appreciate you help identifying those files.
Now, however, I am getting an error when flashing RR everything flashes like normal, but at the end I get a red error:
"e2001: failed to update vendor image"
and then (obviously) a #7 error as result.
The only thing I can see that may be the cause is my device does not have a "Vendor" partition (though it didn't the first time I installed RR, either).
I'm in 3.2.1-8 by NFound then:
Flash A2017x_LineageOS15.1_UniversalBootstack_v2
Flash Modem
Flash RR
Then the error.
Any idea on how to fix this issue? I appreciate your help.

:cyclops: you're not late to the party at all. The rom development has got a huge boast now since we can rely on Orden's sources.
I'm on Pie ofc and not on Oreo anymore since this all is happening. Slim would be ok but get a taste of this all going from PE over RR, VIPER, Havoc, LOS16....and more in the pipeline
Choices enough. My preference till now is ViperOS PIE
So enjoy the ride

Great work. Please do not be deterred by the low interest in your pie roms thus far. I believe in time the interest will pick up. Please keep at it.
@raystef66
Thx for the ROM it's really nice. Booted on the first try. For now I have one issue though. Can't get VoLTE to work. On the lastest Liquid Remix with VoLTE MOD and Speedy vendor I have working VoLTE. I can call and receive calls. On latest Resurrection Remix, ViperOS, DotOS when I select LTE only I can't get any signal. I've tried flashing Oreo modem but that didn't help either. Without selecting this opition I can't get working VoLTE. What could be the problem here?

Thnx ! Afaik VoLTE works out-of-the-box on ViperOS. @Masterjuggler confirmed that to me.
On RR, DotOS I cannot confirm this. I cannot check this myself since my carrier doesn't provide this.
Also, the Volte Mod isn't suited for device specific roms like the ones mentioned above.
So try ViperOS first and see if you can get VoLTE working
EDIT : updating Viper to latest august sec patches now. So perhaps wait a little bit to flash again

First I tried all these ROMs without VoLTE Mod and then I tried with the Mod. When I choose LTE in IMS app I simply lose signal (No Service). It doesn't matter if it's RR, ViperOS or DotOS. Apart from this on ViperOS somehow Pixel Launcher was force closing.

Like ray said, I had it working fine for me. I even confirmed I had the ims LTE service registration in the phone hidden settings. Didn't have to change anything in the settings, worked on the first boot out of the box. I'm on a t-mobile based carrier for what it's worth.
