So cool, is this documented on Github? I'd love to hear more about it!
Well, I don't know exactly what libs are responsible for the live blur tbh. The S21FE system has them by default, that's why my ROM has the blur.
I've documented all the steps needed to use S21FE system here:
Basically I take S21FE stock system and pack it together with A52 stock odm, product and vendor to create a brand new super.img
Most hardware stuff is inside stock vendor, so most of the things will work out the gate.

Hello! Can you say, is there any changes in ROM related to ADB/USB stuff, that you did by yourself or just differs from a52?

I have a52 4g, android 12. I followed your instructions, flashing "Super" ok, but after i flashed "RayOS" I selected power up then answered all the questions, after that all red, access denied. I restarted and it went into boot loop.
I used recovery and recovered before falshing anything.
What did i do wrong when flashing?

edit: I flashed it again and it worked. I'm not sure why, but something went from when flasing last time.

    Ok so it seems a lot of people are becoming a bit nervous about this project being dead.
    First of all, I want to thank all of you for the interest in the ROM. It's nice to see that a lot of people like it and are looking forward to new versions of it.
    However, I have to make it clear that I'm not a big fan of monthly security updates.
    I think it's great for users who never root. Samsung releasing updates for this user base is fantastic and I'm happy for you, but for rooted users I think it's a bit unnecessary. Most of the time, security updates don't really add much if anything at all. My biggest issue with security updates is the fact that I have to make the same edits over and over again for every single month update (if you're curious as to what edits I make, you can easily check it out here:
    And while in theory the amount of work can be reduced by doing a comparison between both previous and newest month builds, I really don't want to spend time or the disk space on extracting two different months and checking folder by folder what's new and what's still the same when I may end up doing the exact changes anyway. I think people who are on Telegram know this about me but I just wanted to put it out there.

    Now, when it comes to OneUI5. I know it's around the corner and everyone's excited about it but I won't really work on it for a while. The point of my ROMs has always been to fix things Samsung likes to break for rooted users. This includes smart view, health, secure folder, etc... and I depend mostly on devs sharing fixes. Some fixes aren't available right away and I'm not skilled enough on figuring them out myself. I'm able to edit smali and follow the guides a lot of great devs like to share to fix some services but I'm not able to figure them out myself.
    Another potential issue that could pop up is that the kitchen I'm using no longer can create images based on newer Android versions. Unfortunately, SuperR's been very busy from what I've seen so if there's any issue on Android 13 images, then I won't even be able to make a ROM.

    That being said, I may work on a stock version of Android 13 with a few things modded just to test the waters. If that's successful then I'd try another S21FE port and start working from there. I may release it, I may not. Only time will tell. There's no October patch because there's nothing important in it, so I decided to skip it.

    TLDR; This project is not dead. I don't like monthly security updates. I won't work on OneUI 5 right away and if I do, I still don't know if I'll release it or not, all depends on how things progress.

    Here it is, a system port of S21 FE. It was easier than expected and works surprisingly well. This will be the definitive edition of RayOS moving forward. Take time to read the FAQ or else I will probably ignore you :)

    If you feel I missed you, please give me a PM so I can add you
    So far it looks like the OneUI 5 ROM may be a reality.
    Quickly made one with the Russia OUI5 Release and it's been pretty smooth
    I may publish it soon, just as a stock modified with a few added features.
    Sorry if I've been late on updates, been real busy lately.
    Just wanted to confirm that yes, August update is in the works
    My goal is to fix Single take and Gallery remaster in Gallery (been making great progress on both)
    I don't have an ETA but rest assured this is my priority so far
    Hopefully I can have it done soon
    After weeks of being busy and new developments happening, I should be able to finally release the September build this week

    The changelog so far in September is the following:
    - Attempt to fix wide angle camera on Pro video/camera mode, I don't remember if this is available in stock
    - Advanced Reboot Menu, allow you to add things like "Reboot to recovery" or "Reboot to Download Mode" to your power menu
    - Fix for Samsung Health. You will no longer need to download any patched version, you will be able to just download the app from Galaxy Store
    - Added Screenshot and VoLTE buttons in quick settings [CSC features, make sure to install them when asked in installer]

    And I think overall stability. I'm still on testing phase but hopefully a release should be available this week
    Thanks for being patient :)
