FAQ:

[(°_o)]

Known Issues:

• Lagginess ofc, due to our device being old
• Sometimes SystemUI gets killed due to low memory and we get Black Screen of Death

 

[(°_o)]

Install Instructions :

[WARNING]:
You must be already on at least Lollipop/Marshmallow ROM and have latest TWRP 3.1.1.
You must format /data as f2fs in TWRP.
Bootanimation is working since build #3.


You should already been familiar with flashing custom ROMs before.
And know how togo from gingerbread -> nougat.
Please check other threads for that..
If someone wants to contribute install instructions for this ROM.
I will be happy to add here and give credits.

Gapps
I havent tested GAPPS.. but I can guess the performance will be horrible with it.
However, I have included the patch for microG GmsCore signature spoofing. So you could try that.

Additional Info:

• Built from latest LineageOS 14.1 Sources.
• Latest kernel from @xc-racer99 aosp-7.1 branch
• Live wallpapers, LineageOS Updater, Weather Service removed for low memory footprint.

[RC02]

I'm delighted that there's still someone who is working on this device. I'll be appreciated to wait for a more stable version of nougat.

 

[MYEUHD]

The rom is indeed quite stable.
However, Webview doesn't seem to work. I think you should take a look here.
Also, built-in root with the Su-addon doesn't work.
And flashing a Magisk or SuperSu zip (made by @xc-racer99 ) resulted in a bootloop, but I was able to access the recovey.

Expect lot of stuffs dont work at the moment.. listed in Not working.
About webview I will try to replace it.

Magisk and SuperSu try to patch boot.img and ramdisk.. and our device uses a very hacky way to load ramdisks.
I will create a patched ramdisk with latest Magisk then..

 

[d.j.byrne.51201]

This has to be the fastest Nougat ROM I've flashed on this phone! Thanks for keeping this amazing phone alive. Can't wait to see it become more stable in the future

Full changelog: build #2

Fixed Audio/Video playback
I had to remove ffmpeg codecs as they were causing hardware decoding to not work.
Hardware decoding is working fine and 720p playback is smooth too..
I've tested without bigmem mode.. I havent implemented bigmem libs for 720p playback.
So please try without bigmem before reporting issues with it.


Fixed Webview
AOSP Webview was somehow not working on our device.. as pointed out by @MYEUHD
The solution he linked was to revert to older webview.
But that is outdated and unsafe so I tried with latest Android System Webview.
It seemed to work so I set it to default.
I havent tried but we can also use Chrome as our Webview..

Switched to OpenGL 2.0
We were stilling using OpenGL 1.4 for rendering.. this shouldnt affect much.. but animations should be smoother
Since we no longer get Shader errors with OpenGL 2.0
Let me know if you find any difference performance wise compared to build #1.

Downloads are in OP.

Status Update:

Project discontinued.
Status Update:
You can skip this paragraph if are not intrested in my long story cut short.

So I have been trying to fix stuffs which means.. rebuilding and flashing the ROM.
Wiping data .. getting logs.. testing if something works.. Repeat

I hadnt really used my Galaxy S1 phone.. It was just lying around a corner of my table getting dust.
Until one day I thought, let's build Oreo for this old time phone.. turns out the battery was RIP due
to not charging it for so long.. so I got a replacment battery then booted to see cm-14.1 build by
Coldwindofnowhere and missing IMEI which I sucessfully restored after creating a thread here.
Again thanks for that to @xc-racer99 and @MYEUHD

So I started out device trees and repos based on Coldwindofnowhere and xc-racer99
and made it compatabile with Oreo. And thanks to rInanD0 I was able to pick stuffs necessary on
kernel side.

Then me and @xc-racer99 discussed some stuff and I picked changes from Unlegacy-Android gerrit to properly do some stuff.. I fixed lots of stuffs.. but I couldnt get the display to initialize... so I decided
to wait for Unlegacy-Android for their take on Galaxy Nexus which shares same GPU as us to bring up Oreo first.

In the mean time, I thought again.. why not build Nougat for now.. so I again setup device tree and repos for
nougat. and we are here..

Okay so I havent really used my Galaxy S1 let alone this ROM.
This ROM does seem fast while moving around just after a first boot.
And really I hadnt installed or used any apps besides the one that came with LineageOS.

But today while trying to fix Camera, I had to actually take photos. Oh, and the reason camera was not working
was due to I had disabled building of Camera HAL in Oreo which stuck around... big derp

So camera preview was working now.. Snap camera wasnt savinf photos at first..
so I thought to install Open Camera.. I installed F-Droid.. then Open Camera..
Then I clicked some photos which seemed to be saved.
There were a lot of photos created so I decided to delete them.

But Files app wasnt deleting them.. must be a permission issue?
So i installed a file manager from F-Droid and deleted the photos.
Good enough.. then I thought I need to download these apps again after a data wipe..
Lets backup them.. so I installed an apk backup again from F-Droid.


While it was downloading.. BAM Screen went all BLACK.
I tried clicking home button but nothing.. then I clicked power button nothing.
Then I hold power button.. i got the options...
Now I was reminded of this bug which has been around since Lollipop? or Marshmallow days..

Screen going all black.. back then Coldwindofnowhere predicted it might due to out of memory issues..
And he is right.. I had adb running so I checked free memory and swap.. The swap file was and memory was nearly full.

I checked dmesg for logs... then I saw lowmemorykiller killing all kinds of stuff.. but there was only one time it killed this..

lowmemorykiller: Killing 'system:ui' (5642), adj 902,

And thats the reason for the black screen.. Now we all know this device doesnt have much memory.
So the option would be to not install many or any apps.. on this option..
Ofcourse I could try to get CMA working properly.. which adds just around 70-80mb I guess..
And we could just white list system ui to not get killed.. but then it would kill other important processes..

So I've decided to stop working on Nougat. I dont wanna give people false hope of *stable* nougat.
I will still upload a build with Camera fixed.. Well video recording still doesnt work.. Looking at logs.. i need to resurrect
the old way of video buffer. which got removed in Nougat.

And while Project Nougat is offically discontinued, Project Oreo is still alive just paused.
I will at least get Oreo bootanimation on this device.

Thanks for trying out this short lived nougat ROM.

Full changelog: build #3

Switched kernel from @Coldwindofnowhere to @xc-racer99
I think xc-racer99 kernel has better memory management. since the lowmemory killer doesnt kill many processes..
However I did make some changes to it.

• Disabled CMA
• Enabled and set zRAM to 1/4 of total memory
• Some kernel build optimizations.

Note that.. this kernel doesnt have BigMem Support so wer'e stuck with 383MiB ram for now.

Fixed Bootanimation
Yeah.. that was a my mistake.. err..
At least you know its booting now.. but since we use pre-odexed ROM first boot shall be done in 5 minutes now..

Fixed Camera
Taking pictures should work now. Video recording is broken.. It needs to updated for Nougat..

Added Magisk in ramdisk
Latest version 14.0. Just install magisk manager AND DONT TRY TO PATCH BOOT.IMG..
We use very differnet system for boot.img and ramdisks..
I will try to update Magisk to latest version.

Fixed a big mistake in updater
https://github.com/galaxys1-nougat/...mmit/a6f51178503a01f6b1e7b0c8222e875392af8a8e
Flashing boot.img would actually result in wiping it in some cases..
If you had troubles installing this ROM or any ROMs in the past.. this might be the case..

 

[laharl_22]

Error 7 is assert error... which I guess is coming from updater script..

You dont need to restore whole stock ROM..
I have built a twrp only recovery image... so you can just straight boot to recovery after Odin..

You can also flash recovery.img from heimdall .
